Sewage treatment workers refer to engineering personnel who specialize in using various methods to separate pollutants contained in sewage or convert them into harmless substances, thereby purifying sewage. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. A method for treating industrial sewage belongs to the technical field of sewage treatment. The method is to lead the sewage to the water collection tank, adjust the pH of the last cell of the water collection tank, use a first-level dissolved air water pump to lift it to a first-level pressure dissolved air tank, and at the same time inhale air and condensed decolorizing agent, which will be in the first-level pressure dissolved air tank. The first-level saturated gas-dissolved water in the first-level air flotation tank is suddenly released to the first-level air flotation tank to form the first-level treated water. Related systems, sewage treatment process , discharge outlets and various discharge indicators, sewage sources and water quality changes, drainage water quality standards , various sewage treatment technologies, basic knowledge and technical parameters of the main equipment of the system, commonly used sewage treatment Basic knowledge of instruments and electricians, knowledge of cleaner production and circular economy construction, etc.
The current water pollution situation in our country is "partly better, but generally worse". With the industrial transfer of enterprises, the pollution has spread to rural areas, causing surface water in rural areas to be seriously polluted, making it difficult for people to drink water. Water pollution has also caused large areas of my country's lakes to become nutrient-dense and their area has shrunk rapidly. In addition, red tides have frequently occurred in coastal waters and algae have grown wildly, and the wildly growing algae can also block the water pipes of water plants. Therefore, it is urgent for to protect water resources and .
