摘要
以受污染湖水为研究对象,通过小试和生产试验,考察了预氯化／粉末活性炭(Cl2/PAC)与高 锰酸盐复合刑(PPC)预氧化对水中有机污染物,藻类以及由其引起的臭、味的去除效能．通过色质联 机分析,探讨了2种工艺的除污染特性．结果表明,由于PPC兼具氧化,吸附和架桥作用,PPC预氧化 能够显著的提高对有机物,藻类及臭味的去除效率,处理效果明显优于Cl2／PAC工艺．
Laboratory and full-scale experiments were conducted for enhancing organic pollutants and algae removal of polluted lake water by pre-chlorination combined with powdered activated carbon （Cl2/PAC） and potassium permanganate composite （PPC） pre-oxidation, respectively. GC/MS analysis was carried out to discuss the characteristics of pollutants removal by using the two pre-treatment techniques. The results indicated that PPC pre-oxidation enhanced algae and organic pollutants removal owing to the oxidation capacity of potassium permanganate, the adsorption by manganese dioxide produced in situ and the increased association of algae both with manganese dioxide and with each other. The results also showed that Cl2/PAC process have limited effectiveness for organic pollutants removal.
