摘　　要： 为去除饮用水中有机物和Ames致突变物,以臭氧化-活性炭与膜工艺对某地自来水进行深度处理,结果表明:原水高锰酸盐指数由2.78 mg/L降至0.96 mg/L,去除率为65.4％,A254由0.096降为0.012,去除率为87.5％,DOC由2 421.3μg/L降为1 136.3μg/L,去除率为53.1％;Ames试验TA98+S9和TA98-S9的MR值由原水的8.450和8.065降为出厂水的1.600和1.550,说明该工艺具有良好的去除有机物和Ames致突变物的能力。O3氧化去除了较多的Ames致突变物,活性炭单元Ames致突变物的去除负荷较低。 Drinking water was treated using both O3 + AC process and membrane technology with permanganate reduced from 2. 78 mg/L to 0. 96 mg/L at a removal efficiency of 65. 4% , A254 reduced from 0. 096 to 0. 012 at a removal efficiency of 87. 5% ,DOC reduced from 2 421. 3μg/L to 1 136. 3μg/L at a removal efficiency of 53. 1 %. The MR values of TA98 + S9 and TA98 - S9 were reduced from 8. 450 and 8. 065 to 1. 600 and 1. 550 respectively, and this shows that the advanced purification system is fairly effective for removal of organic substances and mutagens from drinking water and for this particular water quality, O3 removed more Ames mutagens than AC. The Ames mutagens removal lord by AC is comparatively low for the high removal efficiency by O3. The removal of organic substances and Ames mutagens at each treatment unit is discussed as well.
