LI Duo-song

Abstract

A coagulation-anaerobic hydrolysis-biological aerated filter process used for washing and bleaching effluent advanced treatment was studied.The result showed that the process can remove COD and color of the effluent efficiently.The treated effluent with average CODCr 60.2mg/L and color 55 can meet the national regulation.This simple process has high efficiency and stability.
