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. The aluminum-based inorganic-organic composite flocculant (PAC-JY01) was used to fortify and coagulate the simulated water samples containing humic acid and kaolin. The coagulated effluent was subjected to ultrafiltration. The effluent quality before and after ultrafiltration and ultrafiltration membrane The results showed that the optimal dosage of PAC-JY01 was 3mg / L and the optimum pH was 6 in the coagulation-ultrafiltration combined process. Under the optimal conditions, the removal rates of UV254 and turbidity reached 79.30% and 99.70% respectively. Under the experimental operating conditions, the larger flocs easily deposited on the membrane surface and caused membrane fouling.
