高锰酸钾/次氯酸钠氧化去除山地农村微污染水源水有机污染试验研究

Experimental Study on Removal of Organic Pollutants from Micro-polluted Water Source in Mountainous Countryside by Potassium Permanganate or Sodium Hypochlorite Oxidation

目前,中国大部分水厂使用传统工艺对水进行净化处理,其处理微污染水源水时,对水体中有机污染物的去除效果较差。主要研究前处理单元的工艺参数,以重庆地区山地农村水源水为基础,选取该地区内水库水为研究对象,研究氧化剂:高锰酸钾、次氯酸钠对水体中有机污染物的去除效果及分析去除机理,试验结果表明高锰酸钾最佳工况:投加量为1.2 mg/L,氧化10 min,次氯酸钠最佳工况:投加量为1.0 mg/L,氧化10 min。

At present,most of the waterworks in China adopt the traditional process to purify water.The purification efficiency for organic pollutants in micro-polluted water by conventional process is poor.This paper mainly studied the process parameters of the pretreatment unit.Based on the mountainous countryside water source in Chongqing,we selected the river water,reservoir water and seisensui as research objects,and we studied the removal effect and mechanism of oxidant(such as potassium permanganate and sodium hypochlorite) on organic pollutants in water bodies.The results showed that the optimum conditions of potassium permanganate were 1.2 mg/L for 10 min preoxidation,and the optimum conditions of sodium hypochlorite were 1.0 mg/L for 10 min preoxidation.
