| 摘 要： | 采用铝基无机有机复合絮凝剂(PAC-JY01)对含有腐殖酸与高岭土的模拟水样进行强化混凝处理,取混凝后出水进行超滤,通过测定超滤前后出水水质以及超滤膜运行状况,探讨PAC-JY01对超滤膜工艺效能的影响.结果表明,在强化混凝-超滤联用工艺中PAC-JY01的最佳投加量为3mg/L,最佳pH=6.在最佳条件下,UV254和浊度的去除率分别达到79.30%、99.70%;在实验运行条件下,较大的絮体容易在膜表面沉积而造成膜污染.

| Abstract: | The composite flocculants made of polyaluminium chloride and polydimethyldiallyammonium chloride (PAC-JY01) were used to treat the humic acid-kaolin simulation of water simples by enhanced coagulation.The effluent from coagulation continued to be treated by ultrafiltration.The objective of this research is to identify the mechanism of coagulation affecting UF due to different treated water quality and operational status of UF. The research shows that, in the coagulation-ultrafiltration (UF) hybrid process, the optimum coagulant dosage and pH value are 3mg/L and pH = 6, respectively. At the optimum condition, the removal efficiency of UV254 and turbidity are 79.30%, 99.70%, respectively. In test conditions, the larger flocs are easy to deposit on the membrane surface causing membrane fouling. |
