摘要
采用强化混凝与粉末活性炭吸附组合工艺去除饮用水中的百菌清。结果表明,针对原水中不同浓度百菌清(65.55、212.81、316.89、396.06、543.35μg/L),调节PAC投量(10、20、30、40、50mg/L),吸附30min后,再投加10mg/L聚合氯化铝,混凝沉淀出水中百菌清浓度分别为3.34、2.50、2.58、2.60、2.92μg/L,满足《生活饮用水卫生标准》(GB5749-2006)要求。此方法操作方便、经济有效,可作为水厂应急预案。
The combination of enhanced coagulation and powdered activated carbon was used to remove chlorothalonil in drinking water. The results showed that according to different original concentrations of chlorothalonil （65.55, 212.81,316.89, 396.06, 543.35ug/L）, adjusting PAC dose （ 10, 20, 30, 40, 50mg/L） and adding 10mg/L polyaluminium chloride after adsorption for 30min could make the concentrations of chlorothalonil in effluent of coagulation precipitate meet the ＂Sanitary Standard for drinking water＂ （GB5749-2006）, which were 3.34, 2.50, 2.58, 2.60 and 2.92ug/L respectively. This method is effective, convenient and couldbe the economical operation as emergency preplans for waterworks.
