摘要
以A市受污染水源水为研究对象,通过烧杯试验考察了高锰酸钾复合药剂(PPC)预氧化工艺的效能.结果表明,PPC预氧化能够明显降低沉后以及滤后水浊度、提高对UV254、CODMn指标的去除效果,提高对致病微生物灭活作用,同时降低氯化消毒副产物前体物.并认为PPC优异的除污染作用是由于高锰酸钾氧化作用、新生态水合二氧化锰的吸附及催化作用以及PPC各组分间的协同效应等多种因素共同作用的结果.
effects of pre-oxidation process with potassium permanganate composite （PPC） are studied in laboratory scale, with polluted raw water sample of A city. The results showed that the turbidity of settled water and filtered water are clearly reduced, the removal effect of UV254 and CODMn index are improved, the inactivation effects to pathogenic microbe am improved, and prectusors of chlorination disinfection by-products are reduced by pie-oxidation of PPC. It is considered that the outstanding effects on pollution removal of PPC are the results of combined actions between multiple factors of oxidation action of potassium permanganate, adsorption and catalysis effects of newly-formed hydrated tmanganese dioxide, and synergistic effect between the components of PPC.
