摘要
采用混凝法对高浓度合成洗涤剂生产废水进行预处理 ,去除废水中大量的 SS、油脂类物质及表面活性剂 ,出水与其他低浓度废水混合进行生物氧化处理。试验结果表明 ,混凝气浮法对 COD、SS及油脂类物质去除效果明显 ,COD去除率为 35 %～ 5 6 % ;在废水含盐量较高的情况下 ,生物氧化法仍有较高的处理效率 ,COD去除率达到 70 %～
High concentration detergent wastewater was pretreated by coagulation flotation to remove SS,oil substance and detergent.Then the effluent mixed with other low concentration wastewater was treated by biological oxidation.The results show that coagulation flotation is very effective for the removal of SS and oil substance and COD removal rate is 35%～56%;the efficiency of biological oxidation is still high (COD removal rate of 70%～95%) even when the wastewater saltness is relatively high.
