地表水厂高锰酸钾预氧化效果研究

Studies on effect of purple salt preoxidization in surface water plant

当地表水厂原水中的有机物含量较高时 ,采用预氯化措施易生成致癌、致畸、致突变的“三致物质” ,其中以卤代副产物居多。为了降低卤代副产物的含量 ,提高地表水厂出水水质的毒理学安全性 ,提出了用高锰酸钾预氧化代替预氯化的方法 ,对预氧化的效果和高锰酸钾的最佳用量进行了研究 。

When the content of organic substance in raw water in surface water plant reaches a higher degree,taking prechlorination measures easily produces poisonous substances, which usually results in cancer,deformity and accident.Most of them belong to the byproducts of halogeno.In order to reduce the content of halogeno byproducts.and improve the toxicologic safety of water quality from surface water plant,a new method is pointed out,which is to replace prechlorination with purple salt preoxidization .The effect of preoxidization and the best amount of purple salt are studied,and the economic benefits are analyzed.
