Background

The original physical property or chemical property of the pure water is changed after the pure water is used, and the pure water becomes wastewater containing different impurities. The chemical wastewater is the wastewater such as process wastewater, cooling water, waste washing water, equipment and site washing water and the like discharged in chemical production. If the waste water is discharged without treatment, the waste water can cause pollution of different properties and different degrees of water bodies, thereby harming human health and influencing industrial and agricultural production.

Domestic sewage is mainly from domestic water, and the largest source is washing and kitchen water. The rural domestic sewage is influenced by factors such as living habits and cultural traditions of residents, and has the characteristics of unstable water quality, dispersed discharge time, large difference of discharge amount in different seasons, uneven discharge in different regional environments and the like. Most rural areas in China do not have sewage drainage systems and treatment systems, and sewage is discharged to be directly dumped along rainwater ditches or road surfaces. Although water in the sewage can evaporate, most organic matters can be left on the surface of a soil layer to be washed with rainfall and finally return to rivers, lakes and the like to cause water pollution. Untreated sewage not only has a severe impact on the local environment, but also has a damage to the entire natural environment. In the manufacturing industry, such as clothing factories, cloth factories, paper factories, fertilizer factories, etc., the industrial wastewater contains a large amount of impurities, flock, etc.

If the sewage is directly discharged without being treated, the environment can be polluted, and simultaneously, underground water and surface water are polluted, and the life of human beings is finally influenced.
