Description

technical field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a wastewater treatment system. Background technique

[0002] With the development of the economy and the advancement of urbanization, the discharge of industrial sewage and domestic sewage is also increasing year by year. Generally, there are many enterprises around the rivers in the city, including leather factories, waste engine oil processing factories, electroplating factories and other heavily polluting industries. These enterprises are basically heavy polluting enterprises, such as leather wastewater, with large fluctuations in water quality and quantity, high concentration of suspended solids, easy corruption, large amount of pollution, and wastewater containing toxic compounds such as nitrogen, phosphorus, sulfide and cadmium. The oil spill from the waste engine oil factory also pollutes the water very seriously. Basically, every 1L of engine oil ...
