针对常规工艺难以去除微污染水库水源水中嗅味、有机物的问题,采用化学预氧化法作为处理工艺,考察投加二氧化氯、高锰酸钾、单过硫酸氢钾和紫外/单过硫酸氢钾这4种方式对嗅味、有机物等指标的去除情况,分析对嗅味和有机污染物的去除效果。试验结果表明:与常规工艺相比,4种预氧化方式对嗅味和有机物均有较好的去除效能,在一定范围内,嗅味、有机物等指标的去除率随着氧化剂投量的增加而增大,继而趋于稳定;比较4种预氧化方式的去除效能,紫外/单过硫酸氢钾、单过硫酸氢钾最好,高锰酸钾其次,二氧化氯较差。
Aiming at the problem that it is difficult to remove the odor and organic matter in the micro-polluted reservoir water by the conventional process, the chemical pre-oxidation method is adopted as the treatment process, and the effects of adding chlorine dioxide, potassium permanganate, potassium monopersulfate and ultraviolet / Potassium, the four ways to smell, organic matter and other indicators of removal, analysis of odor and organic pollutants removal effect. The results showed that: compared with the conventional process, the four pre-oxidation methods have good removal efficiency on the smell and organic matter. Within a certain range, the removal rate of odor and organic matter and other indicators with the increase of the amount of oxidant Increase, and then tend to be stable; Compare the removal efficiency of four kinds of pre-oxidation method, UV / monopersulfate, monopersulfate is the best, followed by potassium permanganate, chlorine dioxide is poor.
