The traditional technique, preozonation technique, granular activated carbon adsorption technique and ozone-biological activated carbon technique were compared on its removal efficiency of organic matter and the THMs formation potential (THMFP) as well. It was found that, as compared with the former two techniques, the last two were more effective in organic matter removal, and the efficiency reached 75% - 90%, while the former only at 50% - 60%. The waterworks that adopted the Grade II source raw water were suggested to use the conventional techniques and seasonal preozonation techniques, while the others were suggested to alternatively select GAC or BAC technique to meet the request of new water quality criterion.
对传统工艺、预臭氧工艺、颗粒活性炭吸附工艺和臭氧 - 生物活性炭工艺去除有机物的效率及其三卤甲烷生成势（THMFP）进行了比较。结果发现，与前两种工艺相比，后两种工艺在去除有机物方面更有效，去除效率达到75% - 90%，而前两种工艺仅为50% - 60%。建议采用二级水源原水的自来水厂使用常规工艺和季节性预臭氧工艺，而其他自来水厂则建议交替选择颗粒活性炭（GAC）或生物活性炭（BAC）工艺，以满足新的水质标准要求。
