How to deal with scouring wastewater?

At present, China's scouring is mainly to clean wool, which contains lanolin, sheep sweat, sheep urine, sheep manure, grass clippings, sediment and other impurities. There are also parasite eggs and bacteria.

Characteristics of fine wool wastewater: rich in oil and fat, large concentration of organic matter, brown turbidity of wastewater, high content of COD, BOD and SS, belonging to high concentration organic wastewater.

In view of the characteristics of scouring wastewater, the air flotation method or coagulation sedimentation method is mainly used to treat wastewater.

Regardless of which method is used to treat the scouring wastewater, depending on the characteristics of the wastewater, a flocculant, polyacrylamide, is required. The scouring wastewater is an organic wastewater. The use of cationic polyacrylamide can effectively remove suspended solids from wastewater, reduce wastewater cod95%, and reduce BOD by 80%. The treated wastewater can meet national first-level discharge standards.
