| 摘 要： | 采用混凝沉淀/粉末活性炭吸附/超滤工艺(简称PAC-UF工艺)处理黄河下游引黄水库冬季原水,中试结果表明:当处理冬季低温低浊水时,聚合氯化铝的最佳投量为6 mg/L,粉末活性炭的最佳投量为20 mg/L;PAC-UF工艺可以将出水的浊度控制在0.1 NTU以下,去除率达98%以上;投加20 mg/L的粉末活性炭能使混凝沉淀/UF工艺对COD_(Mn)和UV_(254)的平均去除率分别提高12%和15%;同时,投加粉末活性炭还能够缓解超滤膜的不可逆污染,但缓解的程度有限.

| Abstract: | Coagulation sedimentation/powdered activated carbon (PAC) adsorption/uhrafiltration process was used to treat the reservoir raw water in the lower reaches of Yellow River in winter. The experimental results show that the optimal dosage of polyaluminium chloride and PAC is 6 mg/L and 20 mg/L respectively when treating low temperature and low turbidity water. The combined process can control the effluent turbidity at less than 0.1 NTU with the removal rate of more than 98%. Adding PAC of 20 mg/L can increase the average removal rate of COD_(Mn). and UV_(254) by 12% and 15% and alleviate irreversible membrane fouling, but the alleviation extent is limited. |
