三种氧化剂预处理有机物、氨氮和锰复合原水的比较研究

针对中国水源水污染严重，多呈复合污染的问题，因此，对常用的氧化剂氧化复合污染的原水进行了研究。主要包括三种水处理药剂臭氧、高锰酸钾和氯对有机物、氨氮和锰的处理效能及抗污染负荷的研究，并进一步从安全性进行了比较。研究结果表明，高锰酸钾可以部分去除水中消毒副产物前驱物，适合复合污染水体；若利用臭氧预氧化，更适用尤以有机物污染严重的水质；预氯化将导致水中消毒副产物生成量增加。

Comparative Study on Raw Water Pretreatment with Three Oxidants

This study focuses on the oxidants commonly used in oxidizing polluted raw water to address China＇s problem of se- rious and compound water pollution. It discussed the treatment efficiency and pollution load of three kinds of water treatment chemicals, namely, ozone, organic compounds mixed with potassium permanganate and chlorine, and ammonia nitrogen and man- ganese, in an attempt to compare the security of them. The research results show that potassium permanganate can remove precur- sors of water disinfection byproducts, applicable to composite polluted water bodies. Ozone is more suitable for treating waters se- riously polluted by organic matters and pre -chlorination will increases disinfection byproducts.
