高锰酸钾预氧化辅助氯消毒工艺处理黄浦江原水

Chlorine Disinfection of Huangpu River Raw Water Assisted by Permanganate Pre-oxidation

目前国内大部分净水处理厂都是采用预加氯消毒工艺,但在预氯化的过程中易生成致癌、致畸、致突变的“三致”物质,降低了出厂水的安全性。文章以上海石化水厂微污染水源水为对象,针对折点预加氯工艺的不足,研究了采用高锰酸钾预氧化作为辅助手段的消毒效果。试验结果表明,高锰酸钾预氧化辅助氯消毒工艺比单独预氯化具有更好的处理效果,并能有效保障饮用水的生物安全性。最后对其进行了经济效益分析。

This paper describes an experiment concerning chlorine disinfection of raw water samples from the micro-polluted branches of Huangpu River in Shanghai in order to investigate the effect of permanganate addition for pre-oxidation in place of the conventional pre-chlorination. The effect of THMs control and phenol removal was studied, cost-effectiveness of the method evaluated as well.
