This paper introduces experimental researches on the treatment of anaerobic effluent of highly concentrated organic wasterwater by coagulator—floculation process. The optimal coagulator and optimal processing conditions are determined by experiments. The results show that the dosage and cost of their triturated cogulator are the lowest, COD removal rate is over 86%, SS removal rate is over 90%,and the end effluent meets the discharge standard.The floc formed has better sedimentation property, and easily be separated from water.After the highly concentrated organic wastewater having been treated by anaerobic treatment,the chemical coagulation can be carried through directly.The aerobic treatment is omitted.This makes the technique simpler and the cost lower.
