高铁酸钾的合成及其处理低温低浊水源水

Synthesis of Potassium Ferrate and It's Performance to Treating Water Resource of Low Temperature and Low Turbidity

采用次氯酸盐氧化法制备高铁酸钾作为混凝剂处理低温低浊水源水。试验表明:高铁酸钾对浊度去除效果好于聚合氯化铝,其剩余浊度为0．2NTU;高铁酸钾具有消毒作用,经其处理的原水细菌总数降为10 CFU/mL,大肠菌群数降为0个/L;在本试验条件下经高铁酸钾处理后的水源水,其浊度和细菌学指标均能满足国家生活饮用水标准。

Hypochlorite oxidation method was used to synthesize potassium ferrate, which was used as coagulant totreat low temperature low turbidity water resoume. The results showed that： potassium felxate is better than polyaluminiumchloride to decrease turbidity value, which could reach 0.2NTU; total number of bacteria is 10 CFUhnL, and the numberof coliform group was 0/L by potassium ferrate disinfection; turbidity value and baeterlological pollution index could reachnational drinking water standard by potassium ferrate at the test condition.
