摘　　要：针对现行的饮用水处理工艺存在的问题,讨论了饮用水绿色处理工艺的概念,并提出超滤-臭氧活性炭和超滤-纳滤的绿色工艺,并对太湖水开展中试。通过考察超滤-臭氧活性炭以及超滤一纳滤对各种污染物、消毒副产物前体物、氨基酸、AOC以及双酚A的去除,并比较常规-臭氧活性炭的相应表现,试验结果表明,臭氧会增加污染物并影响后续工艺的处理;将超滤前置于工艺不仅避免了额外污染物的产生,还可有效提升臭氧生物活性炭的处理效果。试验的两种绿色工艺的去除效果均优于常规-臭氧活性炭。In this study,problems existing in current drinking water treatment process were discussed,and the concept of green drinking water treatment process was also raised,and ultrafiltration-ozonation-activated carbon(UF-O_(3)-BAC)and ultrafiltration-nanofiltration(UF-NF)of green process were proposed.To implement the green process,experiments of pilot scale with Taihu Lake were carried out.Through investigating removal of different pollutants,disinfection by-product precursors,aminos,assimilable organic carbon(AOC)and bisphenol A by two green processes proposed and comparing corresponding performance for convention-ozonation-activated carbon(convention-O_(3)-BAC),the results showed that pre-ozonation could produce pollutants that affected the subsequent treatment process,and placing ultrafiltration at the front of the treatment process could not only avoid the generation of additional pollutants,but also effectively enhance the treatment efficiency of O_(3)-BAC.The removal efficiency of two green processed was all superior to that of convention-O_(3)-BAC process.
