摘要
采用膜过滤法对某江水、生物滤池出水和常规处理出水进行了分子量分析 ,考察了 2个单元对不同分子量区间有机物的去除率。结果表明 :原水中分子量小于 1K的有机物占总DOC的 80 % ;生物滤池对分子量小于 0 .5K、0 .5～ 1K及 >60K的有机物去除率分别为 2 7.2 %、2 6 .9%和 1 6 .3% ;常规处理对以上分子量区间有机物的去除率分别为 39.2 %、30 .3 %和 2 9.6 %。
Two units were investigated to assess removal efficiency of organic matter in various molecular amounts by membrane filtration analysis of river water, outlet water of biologic filter and regular tail water. Results showed that organic matters with molecular amount less than 1K in raw water account for 80% of DOC, removal efficiency was 27.2%, 26.9% and 16.3% respectively for organic matters with molecular amount less than 0.5K, 0.5～1K and more than 60K by biological filter, while removal efficiency was up to 39.22%, 30.3% and 29.6% respectively by traditional treatment.
