臭氧、高锰酸钾及复合预氧化处理微污染水效果对比研究

Research on the Ozone and Potassium Permanganate Combination Pre-oxidation of Slightly-polluted Water

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、COD‰、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是一种非常有效的水处理技术.

The research object is raw water from Xiaogan, Hubei. Through static experiments, the effects of ozone, potassium per- manganate, and the combination of both to remove the turbidity, color, CODMn, persistent toxic or harmful pollutants removal effi- ciency. Through comparison, the combination of ozone and permanganate is the most effective. With the coagulant 30 mg/L, per- manganate 2. 0 mg/L, and ozone 1.5~2.5 mg/L, all of the three substances achieve the best results. Respectively,turbidity, 90%, color 87. 4 %,COD Mn 82.1%, persistent toxic or harmful pollutants 73 %. The permanganate and ozone water treatment is a very ef- fective composite technology.
