摘要
该文考察了高锰酸钾预氧化对高藻水源水中污染物的去除效果,结果表明高锰酸钾预氧化-混凝沉淀工艺对高藻水中污染物的去除效果比单独混凝沉淀工艺更好。高锰酸钾预氧化工艺的优化结果表明当高锰酸钾最优投加量为1.0 mg/L、混凝剂聚合氯化铝投加量为30 mg/L时,该组合工艺对藻类、藻毒素、嗅味、UV254、DOC及三卤甲烷生成势的去除率分别为83.57%、87.89%、100%、44.3%、45.45%和64.4%。
The removal effect of KMnO4 pre-oxidation for water with high-algae was investigated in this paper. The results show the removal effect of KMnO4 pre-oxidation/coagulation-sedimentation process on pollutant in water with high-algae is better than that of coagulation-sedimentation process. The results of optimization of KMnO4 pre-oxidation show when KMnO4 dosage is 1.0 mg/L and poly aluminum chloride (PAC) dosage is 30 rag/L, the removal rate of algae, microcystin, odor, UV~,~ DOC and trihalomethane forma- tion potential are 83.57 %, 87.89 %, 100 %, 44.3 %, 45.45 % and 64.4 %, respectively.
