五种预氧化工艺处理污染原水的消毒性能比较

观察了水中腐殖酸和乳糖蛋白胨培养液的含量变化对高锰酸钾、氯、氯胺单独处理工艺及高锰酸钾与氯或氯胺联用工艺消毒效果的影响．结果表明，有机物浓度越高，高锰酸钾与氯或氯胺联用工艺与单独氯或氯胺工艺消毒效能相比所占优势越明显，尤其是当水中含有大量有机氮化合物时，采取高锰酸钾与氯或氯胺联用能更有效提高预处理时消毒效能．对有机污染严重的水源水进行预处理时，高锰酸钾与氯或氯胺联用预氧化能够减少有机物对消毒效果的影响，发挥预处理工艺对致病微生物的多级屏障作用，保障供水安全。

Study on inactivation performance comparison of five preoxidation treatment processes with polluted raw water

The inactivation effects of humic acid and lactose peptone culture solution content are inspected with individual application process of chlorine, chloramines and potassium permanganate, and with combined application process of potassium permanganate with chlorine or chloramines. A pretreatment process is approached with better adaptability to polluted water. The results showed that the advantage of combined application processes of potassium permanganate with chlorine or chloramines are more superior with the contents of organic matters increased, compared with the individual application process of chlorine, chloramines and potassium permanganate. The inactivation efficacy of pretreatment is more effectively improved with the combined application processes of potassium permanganate with chlorine or chloramines, especially a great quantity of organic nitrogen compound are existed. Therefore, the influence of organic matters to inactivation efficacy can be reduced with the pre-oxidation processes of combined application of potassium permanganate with chlorine or chloramines in raw water pretreatment process with serious organic pollution. The multi-protection action to pathogenic microbe is enhanced in the pretreatment process.
