In order to welcome the successful convening of the 20th National Congress of the Communist Party of China, we will further strengthen popular science knowledge publicity and improve the awareness of ecological and environmental protection among teachers and students in school. Recently, Putian Municipal Ecological Environment Bureau, Fujian Putian Environmental Monitoring Center Station and Putian College Students' Eleventh Party Branch jointly launched the theme practice activity of "Welcome the Twenty Top 20 Science Popularization to the Future", inviting more than 20 teachers and students to visit and learn and carry forward the Dongzhen spirit, and explore the mystery of the automatic water quality monitoring station.

First, the staff led the teachers and students to visit the Dongzhen Reservoir water quality automatic monitoring station. Under the explanation and guidance of the staff of the automatic monitoring room of the Putian Environmental Monitoring Center Station in Fujian Province, the teachers and students had "zero distance" contact with environmental protection facilities. The staff gave a detailed introduction to the functions and instruments of the laboratory through diverse forms such as theoretical explanations, operation demonstrations, and interactive communication. Everyone followed the staff's footsteps and asked questions from time to time. The staff patiently answered the demonstration operations one by one, and hoped that in today's digital era where everything is connected, students can maximize their professional advantages, use scientific and technological innovation to jointly promote green development, and contribute wisdom and strength to the construction of a beautiful China .

According to reports, the automatic monitoring station of Dongzhen Reservoir water quality is located at the exit of Putian "big water tank" Dongzhen Reservoir . It mainly monitors 12 parameters such as pH, dissolved oxygen, permanganate index, ammonia nitrogen, total phosphorus , and total nitrogen. It can realize uninterrupted and real-time automatic monitoring of the water quality of the reservoir's drinking water source every day. These indicators will be measured every four hours. These indicators can clearly reflect the physical characteristics of water quality and pollutants. In the past, most of them relied on manual detection of water quality in reservoirs, which was time-consuming and labor-consuming and efficient, and the data was not accurate enough. They introduced automatic water quality monitoring stations and applied big data analysis technologies such as the Internet of Things to automatically upload real-time monitoring data to the management platform, and built a smart early warning mechanism of "monitoring whistle blowing, management and maintenance reporting".

Afterwards, everyone went to the Dongzhen Spirit Exhibition Hall to carry out the Party Day activity of "Chasing the Party's Red Footprints and Welcome the 20th National Congress of the Communist Party of China" to further promote the education of party history in depth and practicality. "This is a great migration of selfless dedication, and it is also a hymn of the times without regrets..." The tour guide of the Dongzhen Spirit Exhibition Hall is carefully introducing the construction history of the Dongzhen Reservoir to everyone. The Dongzhen spirit of "unity, cooperation, hard work, and selfless dedication" carries the collective memory, local feelings and ideal vision of generations of Putian people. It is a true portrayal of the Party always thinking and working with the people, engraving a picture of the era in which the Party always has heart-to-heart, shared destiny, and made progress together.

This activity guides teachers and students in school to experience water quality monitoring work, understand the water quality monitoring process, further disseminate knowledge of ecological environment protection, stimulate teachers and students in school to participate in ecological environment protection, and actively participate in and support ecological environment protection practices.
