高锰酸钾投加量对联合工艺处理微污染水影响的试验研究

Study on Combined Process of Treating Slightly-polluted Water by Dosage of KMnO_4

以色度、浊度和耗氧量作为水质评价指标,重点考察了高锰酸钾标准溶液的投加量对粉末活性炭/高锰酸钾联合工艺处理微污染水效果的影响。结果表明：与常规混凝沉淀工艺相比,粉末活性炭/高锰酸钾联合工艺对微污染水色度、浊度和耗氧量具有比较好的去除效果。当联合工艺1L微污染原水中高锰酸钾标准溶液的投加量控制在0.60~0.80 mL时,处理后出水的色度、浊度和耗氧量测定值均完全达到国家生活饮用水卫生标准规定的限值要求。

In this paper,based on the water quality evaluation index of colority、turbidity and chemical-oxygen-demand,it was studied on powdered activated carbon /KMnO4 combined process of treating slightly-polluted water by the dosage of KMnO4 standard solution.The results showed that powdered activated carbon/KMnO4 combined process has better removal effect of colority 、turbidity and chemical oxygen demand,compared with conventional drinking water treatment process.The colority 、turbidity and chemical-oxygen-demand determination of effluent water can completely arrive at the limit values of standards for drinking water quality,when the dosage of KMnO4 standard solution was 0.60～0.80 mL in 1L slightly-polluted water.
