摘要
三卤甲烷生成势(THMFP)随着氯化消毒的广泛使用成为人们普遍关心的新问题.由于THMFP主要由天然有机物(NOM)成分组成,因而常规水处理工艺难于将其有效的去除.臭氧生物活性炭技术不仅具有臭氧氧化、提高溶解氧的优点,而且协同了活性炭的吸附作用和强化微生物的生物降解作用.研究了经该工艺处理后水质参数THMFP与溶解性有机炭(DOC)之间的关系,以及pH.对它们相互关系的影响.结果表明:生物活性炭工艺可以长期稳定去除50.2～59.3%的THMFP.
The trihalomethane formation potential （THMFP） has become a new issue as a result of the popularization of chlorine disinfection. Conventional water treatment was presented with a puzzle that it could not been easily remove because its major components contained primarily natural organic matter （NOM）. Ozone biological activated carbon combined the advantages of ozone oxidation, high DO, adsorption function, and biological degradation of activated carbon. This paper states the correlation of THMFP and dissolved organic carbon （DOC） affected by pH value after treatment by ozone biological activated carbon. After a long period of operation, the technique could remove 50.2 - 59.3% THMFP.
