摘　　要：以上海市两座不同水源的典型水厂为研究对象,分析了可生物降解有机物(BOM)和总有机物(以DOC表征)在水厂常规净水工艺中的变化规律。结果表明,水厂常规工艺对AOC、BDOC与DOC的去除能力均不高,且受水温影响明显,两水厂出水均为生物不稳定性饮用水;DOC主要在沉淀单元被去除,BDOC在沉淀、砂滤单元都有去除,AOC则主要在砂滤单元被去除;加氯可造成DOC(或BDOC)向AOC的转化,使出厂水AOC浓度增加,要确保出厂水的生物稳定性,必须同步削减水中BOM与总有机物的浓度。Variations of biodegradable organic matters (BOM) and total organic matters in two different conventional water treatment plants were investigated in Shanghai. The results show that the removals of AOC,BDOC and DOC by conventional water treatment processes are not efficient,and effected by temperature significantly. The treated water from two plants is biologically instable. DOC is reduced chiefly by sedimentation,BDOC is removed by both sedimentation and filtration,and AOC is decreased by filtration. The a...
