| 摘 要： | 为去除C市D江饮用水中的异嗅,研究了强化混凝/KMnO4预氧化、强化混凝/粉末活性炭吸附和臭氧/活性炭工艺对水中异嗅和CODMn的去除特性.结果表明,臭氧氧化是去除异嗅的关键工艺.强化混凝/高锰酸钾预氧化及强化混凝/活性炭吸附工艺对异嗅和CODMn均有一定的去除作用,需要根据水中致嗅物质的组成和有机物特性进行选择.但当硫醇硫醚类致嗅物质与土嗅素和2-MIB并存时,强化混凝组合工艺无法完全去除水中的嗅味.当进水嗅阈值<35、CODMn<8 mg/L时,臭氧/活性炭深度处理工艺可以完全去除D江水中的嗅味,并且对CODMn也有很好的去除效果,但在水质再恶化时需联合使用强化预处理等工艺方能达标.

| Abstract: | In order to remove odor of drinking water from D river in C City,China,a study was performed on the removal characters of odor and CODMn with enhanced coagulation/KMnO4 preoxidation,enhanced coagulation/powdered activated carbon adsorption and ozone/activated carbon processes.The results show that the ozonation is the key process to remove odor.The enhanced coagulation/KMnO4 preoxidation or enhanced coagulation/powdered activated carbon adsorption have certain removal effect on odor and CODMn.They should be... |
