Co-coagulation flotation -bio-contact oxidation for treating the oily wastewater

摘要：

The co-coagulation flotation and bio-contact oxidation processes are applied to treat oily wastewater in this paper. The COD, SS, animal and vegetable oil, NH4 + -N and TP in oily wastewater were 4000 mg/L, 1000 mg/L, 200 mg/L, 50 mg/L and 200 mg/L, respectively. In effluent they were 14.4 mg/L, 13.3 mg/L, almost 0, almost 0 and 1.72mg/L respectively,And the mean removal efficiency were 98.7%, 99.8%, 100%, 100%, 95%, respectively.
