臭氧和高锰酸钾处理微污染水的比较研究

Study on the Ozone and Potassium Permanganate Oxidation of Slightlypolluted Water

采用静态试验,分别研究了臭氧、高锰酸钾投加量与高锰酸盐指数、浊度、色度去除的关系。试验结果表明,对于低温微污染水源水,臭氧、高锰酸钾预氧化加常规处理能有效地去除有机物。臭氧预投加量为2 mg/L时混凝后高锰酸盐指数、浊度和色度都有较好的去除效果,混凝后去除率分别为24.6%、96.8%和83.3%;高锰酸钾投加量在0.6 mg/L时混凝后高锰酸盐指数去除率为23.6%。但高锰酸钾会引起水中色度升高和锰离子浓度增加。

Studies are conducted on the relation between the dosage of oxone and potassium permanganate and the removal of COD,turbidity and color by beaker static test.The result shows that oxone and potassium permanganate per-oxidation treatment on slightly polluted water at low temperature could effectively remove some part of organic.When the dose is 2 mg/L and oxidation time is 10mins,the COD,turbidity and color of water after precipitation decrease 24.6%,96.8% and 83.3% respectively.When the dose is 2mg/L and oxidation time is 10 mins,COD of water after precipitation decreases 23.6%,but KMnO4 can increase color and manganese ion of water.
