摘　　要：以城市污水处理厂二级出水为试验水样,采用烧杯实验法,考察氯、氯胺、高锰酸钾单独预处理工艺以及高锰酸钾与氯或氯胺联用预处理工艺的消毒效能及对THMs形成的控制性能.结果表明,对于污染严重,尤其是耗氯物质含量较高的污水,氯消毒效果受到极大影响,氯胺消毒的效果要略好于氯消毒的效果,而高锰酸钾与氯或氯胺联用预处理工艺的消毒性能明显优于单独氯或氯胺工艺,并且能够进一步降低THMs的生成量.高锰酸钾与氯或氯胺联用预处理工艺是提高污水回用水水质的一种十分有效的方法.Water samples of secondary effluent from an urban wastewater treatment plant are applied with laboratory experimental method. The efficacy of disinfection and control performance of trihalomethane production are investigated in the pretreatment process with individual application of chlorine, chloramines and potassium permanganate, and with combined application of potassium permanganate with chlorine or chloramines. The results show that the effectiveness of chlorine disinfection is extremely affected by seriously polluted water, especially the wastewater with high contents of chlorine - consumed matters. The effect of chloramines disinfection is better than that of chlorine disinfection. The effect of combined application of potassium permanganate with chlorine or chloramines is clearly better than that of individual chlorine or chloramines disinfection, and the production of trihalomethane is reduced additionally. Therefore, the pretreatment process of combined application of potassium permanganate with chlorine or chloramines is an effective method of improving water quality of wastewater reuse.
