| 摘 要： | 以城市污水处理厂二级出水为试验水样，观察了氯、氯胺单独消毒工艺以及高锰酸钾与氯胺协同消毒工艺的消毒效能，同时比较了投药总量相同条件下单独氯胺消毒工艺及高锰酸钾与氯胺协同消毒工艺的消毒效能以及对THMs生成的影响。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，而高锰酸钾与氯胺协同消毒工艺的消毒性能明显优于单独氯胺消毒工艺，并且能够进一步降低THMs的生成量。因此，高锰酸钾与氯胺协同消毒工艺可以使处理后水质从微生物安全性到化学安全性两方面均得到提高。

| Abstract: | In this paper, the disinfection effect of chlorine, chloramine and potassium permanganate combined with chloramine with secondary effluent of a wastwater treatment plant used as the rawwater was investigated, and the disintection effect of chloramine alone and that of potassium permanganate combined with chloramine and the amount of THMs produced at the same dosage were compared. The results indicated that when heavily polluted water with high centents of organic matters and ammonia, disinfection effect of chloramine is more or less better than chlorine whereas the synergic disinfection effect of KMnO4 and chloramine obviously better than that of chloramine and furthermore, the amount of produced THMs decreased, therefore the microbiological and chemical safety of water improved. |
