Public utilities such as water supply, gas supply, lighting, and drainage are closely related to residents' yearning for a better life and urban development. Over the past five years, Changzhou's urban utilities have developed steadily, helping the urban living environment to comprehensively optimize and the quality of residents' living, developing utilities, bravely serving as a benchmark demonstration, get up in the morning, turn on the faucet to enjoy clean tap water; at noon, turn on the gas to make a pot of delicious hot meals; drive after get off work, rows of LED street lights on the elevated road around the city are like brightly lit corridors, illuminating the way home; when going out on rainy days, don't worry about water filling up and wetting your trouser legs... This has become a common life for Changzhou citizens.
Beautiful light and shadow tell the story of Changzhou Canal
Water supply, gas supply, lighting, drainage and other public utilities are closely related to residents' yearning for a better life and urban development. During the 13th Five-Year Plan period, our city will focus on improving people's livelihood, vigorously develop public utilities, build a good business environment, and continuously meet the growing needs of residents.
provides guarantee for safe use of gas and creates a first-class business environment
, wearing protective clothing, goggles, masks, gloves, and carrying tool kits, Shan Yongqiang, a staff member of the Hong Kong Huahua Gas, came to Ms. Chen's home in Haojun Garden, to connect, detect leaks, debug and other work on the gas stove and water heater in her kitchen. For more than two hours, Master Dan climbed high and fell down and drilled the cabinet to install it. He was so busy that he was sweating profusely. After the installation, he guided Ms. Chen to turn it on and explained precautions such as safe use of gas.
This is a microcosm of the installation and debugging of gas facilities for the quarantined households in our city on February 25 this year. During the epidemic prevention and control period, in order to ensure the daily living, production and resumption of work of nearly 700,000 customers in Changzhou, the service positions of Honghua Gas installation, maintenance, emergency, hotline, dispatch, station, business processing, etc. have been maintained normally.
Changzhou Ganghua Qinglongmen Station LNG Release Station
As the earliest public enterprise to introduce Hong Kong capital in our city, Changzhou Ganghua Gas Co., Ltd. has always adhered to the tradition of respecting customers, is oriented towards customer needs, and continuously improved the management model to provide guarantees for gas customers' safe and secure use of gas. In order to better serve citizens and protect the safety of the pipeline network, in January this year, Changzhou Ganghua introduced two gas sniffing dogs, and in June this year, the vehicle-dog-linked leakage detection project was launched to find the leakage points of the pipeline network more efficiently and accurately. This is also the first pilot promotion of the project in the province.
In recent years, under the guidance and support of the Municipal “Decentralization, Supervision and Service” Reform Coordination Leading Group and the Municipal Housing and Urban-Rural Development Bureau, Changzhou Ganghua has invested no matter how to improve gas supply guarantee capabilities, make service methods more efficient, and strive to create a first-class business environment.
In May 2017, Changzhou Ganghua started construction of the third phase of natural gas utilization high-pressure pipe project, with a total investment of more than 40 million yuan. Gas high-pressure transmission and distribution pipelines were laid along Provincial Highway S239, Shanghai-Nanjing Expressway and Chunjiang Road. The entire line includes 14.4 kilometers of steel pipes with a diameter of 500 mm and 2.5 kilometers of Changzhou-Danyang Unicom pipes with a diameter of 400 mm, as well as 15 kilometers of high-pressure pipes for China Resources Zhonglou Power Project. After the natural gas is operated using the third phase high-pressure transmission and distribution pipeline, the gas source of the Ganghua Jintan gas storage can be transported to the Changzhou District through the Jintan and Danyang high-pressure pipeline networks, providing strong guarantees for peak gas use in winter and injecting strong new impetus into Changzhou's economic and social development.
In order to ensure winter gas supply, Changzhou Ganghua invested nearly 15 million yuan in 2018 and completed the construction of three temporary LNG release stations within one year, increasing the capacity of liquefied natural gas released in the city to 600,000 cubic meters every day. During the peak period of gas use, Changzhou Ganghua also actively contacted upstream companies and tried to obtain unplanned gas supply support; contacted and identified multiple LNG suppliers in advance, and purchased regardless of costs when the gas supply was tight, so as to minimize the gap in natural gas supply, so that enterprises can use gas with confidence in the cold winter.
From 2015 to the present, more than 140 industrial enterprises in Changzhou Port have implemented the "coal to gas" project, and provided support in terms of transformation costs, natural gas prices, etc., so that the total energy costs of these enterprises after "coal to gas" were effectively saved. In 2019 alone, the company reduced its gas use costs by more than 50 million yuan, and saved nearly 400 million yuan in total for the company over the years, so that industrial enterprises would not be bothered by costs and use gas happily.
ensures water safety and lets people drink "safe water"
On November 12, in the water and gas mutual service window of the Boai Road Customer Center of Changzhou Ganghua Gas Co., Ltd., in less than 10 minutes, Mr. Zhou, a citizen, completed the transfer, payment, and electronic invoice printing of tap water and gas. "Just go to one department and provide only one piece of information, you can handle water and gas business, which greatly saves time." Mr. Zhou said happily.
"Since March this year, General Water Department has launched a 'water and gas closure window' in the municipal government service center and gas window, and has opened a special window for the four main business halls in the city and gas inter-operation business. From January to October this year, users have paid more than 135,000 payments through online channels, completed more than 24,000 online transfers, vigorously developed smart water services, and pressed the fast forward button for services." A staff member of Changzhou General Water Company introduced that over the past five years, General Water Department has focused on people's livelihood hot spots, improved high-quality services, fully served Changzhou's economic and social development, and focused on building a new pattern of water services.
Water and gas closure window provides convenience for citizens, and can handle both water and gas services at one time.
Water quality safety is the core link in building a water supply safety guarantee system. In order to ensure water quality safety, in recent years, General Water Department has achieved the full process of controlling the water quality from the source to the faucet, established and improved a three-level water quality test system, and the passing rate of factory water and pipeline water quality has always reached 100%; for the first time in the country, the "same city, same network, same price" model of secondary water supply has been realized, which has better solved the problems in secondary water quality and other aspects. In 2016, the company invested 420 million yuan to build a full-scale deep treatment and transformation project of tap water produced by Xishiqiao Water Plant and Weicun Water Plant. It adopts the "ozone activated carbon" deep treatment process to minimize the possible impact of raw water quality fluctuations on the tap water production process and achieve a leap from "safe water" to "high-quality water".
htmlIn the past 2005, General Water Department has invested more than 10 million yuan each year to carry out overall renovation of water supply pipelines in old residential communities such as Baiyun New Village and Qinye Village. This year, more than 30 million yuan was invested to renovate 15 old communities including Wujiaochang East in Tianning District and Yangliuxiang Community in Zhonglou District, which effectively improved the impact of pipeline material on water quality. Now, the water supply pipeline renovation project for 1,425 households and corporate customers in May Day has been launched to win the battle of "agricultural water transformation". In order to effectively implement this people's heart project, the company has also formulated a short-term plan of 5-10 years and a long-term plan of 10-20 years, and established a long-term mechanism for pipeline maintenance and transformation.Weicun Water Plant
Scientific and technological innovation is also frequent highlights. The Changzhou urban water supply safety operation management platform has formed a multi-level water quality monitoring system such as raw water quality monitoring, water plant full-process water quality monitoring, pipeline network water quality monitoring and secondary water supply water quality monitoring. The goal is to realize the comprehensive informatization of secondary water supply pump rooms and operation and maintenance work by 2021, and realize "smart pump rooms and intelligent water supply".
In addition, General Water Corporation has also carried out technical research and development "100 Talent Plan" and management improvement "100 Talent Plan", and has obtained 25 software copyrights, 15 utility model patents and 2 invention patents, adopted a number of targeted and operational suggestions and strategies, and has issued and implemented relevant systems, solving many long-term management problems. As a water supply enterprise, General Water Department also took the lead in applying for the national "13th Five-Year Plan" water special research project "Changzhou Taihu Basin Water Source Drinking Water Safety Technology and Application Demonstration", forming 3 main research results, covering multiple innovative key technologies. After application, it will comprehensively improve the system refined operation and management level of Changzhou's water supply from the source to the leading.
takes lights as the meridian and humanities as the latitude to "tailor-tailored" the night view of the city
At night, the lights are like rainbows and training in the city elevated roads, high-speed rail stations, and civil aviation stations; the gymnasiums and the Grand Theater show the modern atmosphere; the Citizen Square and the Grand Canal are lit up, like brilliant stars... The people who light up the night view of the city are a group of illuminators. "Using lights as the meridians and humanities as the wefts, we tailored the city's lighting to become a city' evening dress that is 'time-oriented, matter-of-fact, and pleasant'."The staff of the Municipal Lighting Office introduced that over the past five years, Changzhou Lighting has continuously expanded and extended new achievements in green lighting, fully exerted the new driving force of smart lighting, and carefully forged a new soul of humanistic lighting. The Municipal Urban Lighting Management Office has just won the honorary title of the 6th National Civilized Unit , which is also the first national civilized unit in the urban lighting industry in our province.
In recent years, Changzhou Urban Lighting has proposed the concept of humanistic lighting in the industry to help the construction of beautiful and livable cities. By decorating the "urban living room" and outlining the nostalgic memory of Changzhou, let the lighting and the city "breathe together". The urban ring elevated building lighting project was launched in June this year, and it has been completed. Three elevated fast roads, including Longjiang Road, Longcheng Avenue, and Qingyang Road 66 331 buildings on both sides of the Speedway, Qinye Road and Xinggang Road have successively "beautiful" them, forming another "night view corridor" after the Grand Canal Landscape Belt.
The urban elevated building lighting project built this year has become another "night view corridor" in our city after the Grand Canal Landscape Belt.
When compiling the "Changzhou City Urban Lighting Special Plan", Changzhou Urban Lighting actively advocated integrated urban-rural lighting, gave functional lighting "urban furniture color", and created exclusive "color" for street lights to echo the surrounding appearance; in order to help the revival of the old city, it is beautiful "longcheng Night Weiyang", and this year explored "street lights on Luohan Road and Hongmei Road WiFi, under the background of implementing "new infrastructure", promotes the transformation of traditional infrastructure; the old canal is themed "Water shadow, color warm, light movement joyful" and spreads the canal culture through intelligent control of audio and projection lamp special effects, telling the story of Changzhou; the cultural square uses light to interpret Changzhou culture, actively helping to build a livable and beautiful Changzhou city, highlighting the theme of "teach me how to not miss her".
Changzhou City Lighting formed a "Little Orange Lantern" volunteer service team, went to the community and children's welfare home, and wrote the "Home Green Lighting Reader", popularizing the concept of green lighting to citizens in a picture-based and text-based way. In East Era 1 20 Landscape Tower, West Taihu Lanyue Bay has opened the "festive mode" of lighting, and carried out public welfare activities such as "helping the new crown fight against the epidemic", "One hour of the earth's lights off", "Focus on autistic children", and the United Nations Diabetes Day "Blue Light Action" in 2020. In 2020, the "Learn Lei Feng Demonstration Point" of the province. In the year since the completion of the "Longcheng Xiaoju Lantern" comprehensive space, it has actively built a civilized practice base, carried out more than 200 civilized practice activities, and was rated as the "3211 Party Member Education Practical Classroom", "Science Popularization Base" and "Social Science Base" in Changzhou.
In order to strengthen energy consumption management, Changzhou Urban Lighting continues to expand its energy-saving results and gradually extends the development experience of green lighting construction and development to villages and towns. 28,000 original facilities LEDs were successfully transformed in the urban area, and the single-light control platform developed simultaneously obtained software copyright. Since the 13th Five-Year Plan, the total power of the facilities under its jurisdiction has increased by 1.91% per year, and the annual average electricity bill expenditure has decreased by 5.73%. The green lighting work has achieved significant results.
As the "steward" of urban lighting, Changzhou Urban Lighting has also adhered to innovation and led by creating the second batch of "demonstration model workers in the city Innovation Studio, editor-in-chief of the editor-in-chief of 4 national standards and 2 industry standards in the past five years. The Jiangsu Province "Urban Lighting Gallery" edited by the editor won the first prize of the "Four Excellences" of the Provincial Science and Technology. During the 13th Five-Year Plan period, the "National Urban Lighting Information Management System" was officially awarded by the Urban Construction Department of the Ministry of Housing and Urban-Rural Development, and the "National Urban Lighting Information Management System" was settled in Changzhou, providing a data basis for urban lighting to play a role in supporting urban construction and developing decisions and participating in smart city construction. Since 2018, our city has successively carried out the use of multi-function street light poles on the Jinling section of the Rail Transit Line 1, and this year it has built the first set of "street lights in the city. 5G" facilities accelerate the transformation and development of traditional infrastructure.
As the "leader" in the drainage industry, Xucheng Yijiang, Chengji
Zhonglou District, Fan Yunxia, a staff member of the Taoyuan Community of Wuxing Street, Zhonglou District, often walks along the Cross River. The river in front of her once turned black and smelly every time she arrived in Huangmeitian. After rectification a few years ago, the river water is now clear and the water ecological environment is beautiful. "Now, when you walk into Five Star Park, you will see the clear Cross River reflecting the blue sky, and you are in a very happy mood. "Fan Yunxia said.
This is a microcosm of the scientific governance of the Municipal Drainage Management Office that paints the background of ecological development. Since the 13th Five-Year Plan, the Municipal Drainage Management Office has taken the attitude of "China's Leader in Urban Drainage" and actively played the demonstration role of a national civilized unit. With the goal of "leading within the province, first-class in the country, and advanced in the world", and has taken it as its mission to protect the clear water of Longcheng. Adhering to the original intention of "seeking cleanliness, seeking purity, seeking innovation, and seeking progress", the city is clear.
In order to promote urban drainage and sewage treatment with high quality, Changzhou drainage has gradually achieved "four full coverages", namely full coverage of planning, full coverage of urban and rural pipelines, full coverage of industry management, and full coverage of technological innovation, playing an important role in Changzhou's ecological civilization construction and improving the living environment.
Jiangbang sewage plant second sedimentation pool
A series of numbers highlight the huge innovation momentum of the Municipal Drainage Management Office: 237 projects including the fourth phase of the riverside sewage project have been implemented, more than 220 kilometers of new pipelines have been built, and more than 1,400 kilometers of digital inspection have been carried out. The capacity of the four sewage treatment plants operating reached 750,000 tons, an increase of 35.7% year-on-year from five years ago, and 100% of the effluent was better than the national strictest standards. Sludge is the first in the country to achieve full quantification, harmless and resource-based disposal. The integrated factory and network and integrated construction, management and maintenance management mechanism are the first in the country. The sewage source supervision model has set a precedent in the country. It is leading the country in the treatment of black and odorous water bodies, sewage treatment performance, pipeline quality improvement and efficiency improvement, and pump station low water level operation. In the past five years, 23 national drainage industry standards have been participated in the compilation of 23 various types of national drainage industry, and more than 120 batches of units have been received to study, becoming a benchmark in the national drainage industry.
The staff of the Municipal Drainage Department introduced that Changzhou's sewage facilities are at the forefront of the country. The Municipal Drainage Department has always adhered to the principle of "moderate advancement, equal emphasis on factory networks, pipeline networks first, high-standard construction, innovation and excellence, and favorable operation and maintenance", and carried out drainage facilities construction with high quality and low cost. The fourth phase of the Jiangbian Sewage Treatment Plant, which passed the completion acceptance not long ago, is the first research on carbon neutrality planning of sewage treatment plants in China. It is a green and low-carbon ecological sewage treatment plant carefully created using the latest domestic and foreign ecology, wisdom concepts and advanced technologies. We will also use the newly added plot on the north side to build an ecological wetland with a treatment scale of 40,000 tons per day. After the sewage treatment meets the standards, it will be deeply treated and purified by the ecological wetlands, give full play to the purification and restoration of the ecosystem, form an ecological buffer zone of the Yangtze River, promote the rest and recuperation of the Yangtze River ecosystem, and play an important role in the protection of the Yangtze River.
Changzhou is one of the earliest cities in the country to fully implement the "clean water project" water treatment in the main urban area. The "clean water project" includes environmental protection pollution control, urban construction pollution interception, and water conservancy living water. Among them, urban construction pollution interception is the fundamental solution, and Changzhou's work is leading the country. In 2016, the Ministry of Housing and Urban-Rural Development held a promotion meeting on the treatment of black and odorous water bodies in Changsha. Changzhou is the only city to be invited to introduce its governance experience. The Cross River (Five Star Park) black and odorous water body treatment project was selected as the 2018 case of urban black and odorous water body treatment of the Ministry of Housing and Urban-Rural Development. On the basis of the original good rain and sewage diversion in the main urban area, Changzhou adheres to scientific and systematic governance, adopts new applicable technologies, adapts to river conditions, and intercepts along the river. Adhere to the principles of "large diversion" of rain and sewage diversion and "small interception" of river sewage interception, effectively solve the problem of the root causes of black and odor on the shore of rivers, and lead the country in many technologies.
In addition, Changzhou has also promoted the comprehensive upgrade of recycling of recycled water. After urban sewage is treated by four sewage treatment plants, including Jiangbian, Chengbei, Qingtan, and Qishuyan, the water quality of the tail water is better than the national first-level A emission standard. In order to enhance the flow of rivers in the city and change the black and odor of rivers, the Municipal Drainage Management Office used tail water to replenish ecological water in multiple rivers such as Xinlong Ecological Forest and Baijiabang, injecting new vitality into the improvement of the river water environment. The tail water is also recycled and used for landscape greening, road washing, industrial cooling water, etc., to realize sewage resource utilization and water resource recycling.In 2020, the high-quality tailwater of the riverside sewage treatment plant serves as the energy source of the "water source heat pump" of the regional energy station of Xinlong International Business District, supporting the operation of regional energy facilities. At the same time, the water source after the heat energy is extracted is once again flowing as an ecological water source to the west high-speed rail ecological park to the Dongfeng Dagou and the west branch of the algae river, forming a "excellent water-source heat pump-live water wetland-natural river channel" with the "excellent water and multiple use, one water" tailwater resource utilization pattern, becoming a shining business card for ecological city construction.
