沉淀-气浮处理再生浆造纸污水

A Treatment Sedimentation-Air Flotation for Wastewater of Paper Making with Recycling Pulp

采用沉淀 气浮处理再生浆造纸污水 ,处理水量 2 0 0 0m3 d。沉淀池进水COD 15 0 0mg L ,气浮池进水COD 936mg L ,出水COD 181mg L ,总去除率 88% ,达到GWPB 2— 1999《造纸工业水污染物排放标准》。

Adopt sedimentation air floatation to treat paper making wastewater making with recycling pulp.It is designed to treat 2 000 m 3 wastewater per day.The content of COD is 1 500 mg/L when the wastewater flows in the sedimentation pool,940 mg/L in the air flotation pool.The final effluent COD is reduced to 181 mg/L.The total remove rate of COD is 88%.That obtain the Discharge standard of water pollutions for paper industry(GWPB 2-1999).
