臭氧、高锰酸钾及复合预氧化处理微污染水效果对比研究

以孝感市府河水为研究对象，采用静态试验，分别研究了臭氧、高锰酸钾及两者复合对浊度、色度、CODMN、持久性有毒有害污染物的去除效果。通过对比分析，发现臭氧高锰酸钾复合药剂对各项的预氧化效果尤为明显。并在混凝剂投加量为30 mg/L，高锰酸钾投加量为2.0 mg/L，臭氧投加量为1.5~2.5 mg/L之间时，各项的去除效果最佳，分别为：浊度90%、色度87.4%、CODMN82.1%、持久性有毒有害污染物73%。说明高锰酸钾与臭氧复合一种非常有效的水处理技术。

Study on the Ozone and Potassium Permanganate Combination Pre-oxidation of Slightly-Polluted Water

The research object is raw water from Xiao gan, Hubei. Through static experiments, the effects of ozone, Potassium permanganate, and the combination of both to remove the turbidity, color, CODMN, Persistent toxic or harmful pollutants removal efficiency. Through comparison, the combination of ozone and permanganate is the most effective; with the coagulant 30 mg/L, permanganate 2.0 mg/L, and ozone 1.5~2.5 mg/L, all of the three substance achieve the best result. Respectively,turbidity,90%、color87.4%、CODMN82.1%、Persistent toxic or harmful pollutants73%, The permanganate and ozone water treatment is a very effective composite technology.
