摘　　要：以多环芳烃和有机氯农药作为有机物评价指标,对某自来水厂常规处理加深度处理工艺,即混凝-沉淀-过滤-炭吸附处理工艺的去除效果评价,并对几种深度处理技术展望。结果表明,检出多环芳烃和有机氯农药均未超出生活饮用水标准(2006)的限值。在研究的净水工艺中,深度处理工艺炭滤对多环芳烃和有机氯农药的去除效果较为理想。强化混凝、臭氧+活性炭和纳滤膜技术是水厂未来经济可行的处理工艺。Removal efficiency of conventional treatment plus advanced treatment in a municipal waterworks and their remainder were discussed using PAHs and organic chlorine pesticides （OCPs） as the organic compounds evaluation index, and some advanced treatments are prospected. The results showed that concentrations of PAHs and OCPs detected in the waterworks were under the relative limit of water supply industry standard in China （2006）. The activated carbon technique is the most efficient treatment for removal. Enhanced caogulation, oxyen ＋ activated carbon and nanofihration are economic and feasible treatment in future.
