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CODMn和UV254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。
Coagulation sedimentation/powdered activated carbon （PAC） adsorption/ultra：filtration process was used to treat the reservoir raw water in the lower reaches of Yellow River in winter. The ex- perimental 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 con- trol 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 CODMn and UV254 by 12% and 15% and alleviate irre- versible membrane fouling, but the alleviation extent is limited.
