摘　　要： 以GAC-NF组合工艺对以太湖水为水源的某水厂出厂水进行深度处理试验研究。结果表明,工艺对TOC的去除率大于90%,其中NF的去除率占49%。NF对阳离子的去除率与离子浓度大小成正比;对阴离子SO2-4的去除率高于一价阴离子(Cl-、F-、NO-3)的去除率。GAC吸附对移码型的致突变物的去除率为49.6%,对碱基置换型致突变物的去除率为20.2%。NF对两种致突变物的去除率分别为94.6%和37.2%,可保证出水Ames试验结果呈阴性。 The investigation with GAC-NF processe on the deep treatment of the water from a drinking water works whese source water comes from Taihu Lake was made. The results showed:(1)Over 90% of TOC in the water was removed, in which 49% is achieved by NF process.(2)The removal rate for cation in the water by NF process is positive proportional to the ion concentration, removal rate of SO2-4 is higher than that of one valent anions(Cl-, F-, NO-3).(3)49.6% removal for TA98 and 20.2% removal for TA100 are reached by GAC adsorption. For the two types of mutagens, 94.6% and 37.2% removal can be reached respectively by NF process. The application of GAC-NF processes can ensure the Ames Tests of the finished water to be negative.
