摘要
采用混凝沉淀-超滤组合工艺进行了城市二级出水深度处理的试验。结果表明,超滤膜对浊度、UV254、COD、PO43--P的平均去除率分别为100%、21.2%、28.36%、31.5%,超滤膜分离系统的产水率为84.6%。超滤前加混凝沉淀预处理,可以提高水中有机物的去除率,同时减轻了膜污染。
Experiment on advanced treatment of the municipal secondary effluent by combined coagulation-sedimentation and ultrafiltration （UF） process was carried out. The results show the average removal rate of turbidity, UV~, COD and PO43--P are 100%, 21.2%, 28.36% and 31.5%, respectively. The water production rate of the combined UF system is 84.6%. The pretreatment of coagulation-sedimentation before ultrafiltration could improve the organics removal and alleviate membrane fouling.
