该文研究了闵行水厂三期和四期的臭氧生物活性炭工艺对水中有机物的去除效果、炭滤池中活性炭的吸附性能及对无脊椎动物的泄漏控制效果。结果表明三期和四期的出水CODMn基本维持在2．5 mg ／ L，出水氨氮维持在0．4 mg ／ L，以上均能满足《生活饮用水卫生标准》（GB 5749—2006）的相关要求；三期活性炭前置导致炭滤池运行周期短，反冲洗频繁，对有机物去除效果较四期差；由于在砂滤之前进行加氯消毒的工艺，闵行三期处理系统对无脊椎动物的年平均去除率为94．0％，略高于四期。

Effects of ozone biologically activated carbon of phase 3 and phase 4 project in Minhang Waterworks on removal of organics, adsorption of activated carbon in activated carbon filter and leakage of invertebrates were studied. The results show than CODMn and ammonia nitrogen of the finished water are 2. 5 and 0. 4 mg / L,respectively,which can meet the requirements of Standards for Drinking Water Quality (GB 5749—2006). In phase 3 project,pre-activated carbon filter makes operation period short and backwashing frequent,and the removal effect of organics is worse than that in phase 4 project;because of chloriniation disinfection before san filtration in phase 3 project,the removal reate of invertebrates is 94. 0%,which is a little higher than that in phase 4 project.
