Urban sewage treatment is generally divided into three levels, which is usually treated with primary treatment as pretreatment, secondary treatment as the main body, and tertiary treatment is rarely used.The effluent from the general factory should be treated at least two levels.
Primary treatment, the application of physical treatment to remove insoluble pollutants and parasitic worm eggs in wastewater;
Secondary treatment, the application of biological treatment method to decompose various complex organic compounds in sewage into simple substances;
Tertiary treatment, the application of chemical precipitation, biochemistry, physical chemistry, etc., to remove phosphorus, nitrogen, refractory organics, inorganic salts, etc.
As to which level of treatment is more reasonable, it should be determined according to the processing requirements of the final effluent.
China's water resources per capita are small and spatial distribution is unbalanced.
With the acceleration of urbanization and industrialization in China, the demand gap of water resources is increasing. In this context, shandong well environmental new materials co. Ltd., as polyacrylamide manufacturer, is committed to contributing to the world's environmental protection industry.
