不同氧化剂对水中微囊藻毒素 LR（MC LR）释放及降解的效果
Effect of Release and Degradation of Microcystin-LR (MC LR)in Water by Different Oxidants
摘要
Abstract
The degradation of microcystin-LR by three different kinds of chemical oxidants (ozone,potassium permanganate and sodium hypochlorite)was discussed in this paper. Meanwhile,both effects of oxidants on release and degradation characteristics of microcystin-LR were also elaborated in algae removal process. The results show that three kinds of oxidants can effectively remove microcystin-LR. When ozone feed rate is 0. 41 mg / L·min and reaction time is 5 min or when dosage of potassium permanganate is 2 mg / L and reaction time is 5 ~ 8 min during the oxidation treatment process of microcystis aeruginosa,microcystin-LR in water can be completely removed. In addition,when three kinds of oxidants treat water containing algae,a certain amount of intracellular microcystins releases into the water,and sodium hypochlorite can seriously damage the cells of algae,resulting in generating a large amount of extracellular dissolved microcystin-LR that is removed ineffectively by conventional water treatment processes and causes security risks of drinking water.关键词
