脱墨废水的混凝——活性污泥的处理

Coagulation and Activated Sludge Treatment of Deinking Waste Water

对脱墨废水采用混凝—活性污泥处理效果进行了研究，结果表明：脱墨废水经过混凝处理，可使BOD5、CODcr和SS的去除率达到64.44%、72.21%和73.93%，混凝后的脱墨废水再经活性污泥处理，其BOD5和 CODcr的去除率达到89%和60%。处理后的废水可循环回用并完全达到国家GWPB2—1999所规定的排放要求。

：An effect of coagulation and activated sludge of deinking waste water is studied.The removed rates of BOD5、CODcr and SS of deinking waste water treated by coagulation are up to 64.44%，72.21% and 73.39%. After being coagulated , The removed rates of BOD5 and CODcr of deinking waste water by activated sludge are up to 89% and 60%.The treated waste water can be up to the standard of GWPB2-1999 and be a recycle utilization.
