摘　　要：长江南京段的水质虽能常年保持在Ⅱ～Ⅲ类，但原水中甲苯、三氯苯和邻二苯甲酸二丁酯等微量持久性有机物检出表明长江南京段的水源水已呈现微污染特征。该文以长江南京段原水作为研究对象，以提高出水水质为目标，研究了水源水持久性有机物的种类和特定有机污染物（阿特拉津和氯苯类化合物），考察强化滤池、活性炭滤池工艺去除水中污染物的效能。结果表明长江南京段水源水中检出持久性有机物为65种，其中以脂肪烃类有机物、芳香类有机物、酯类有机物、醇类有机物及酮类有机物为主，5类有机物的总量约占总的持久性有机物的90％以上；长江南京段水源水中未检出阿特拉津，检出1，2，4三氯苯，其含量为0．249μg／L。强化过滤和活性炭过滤工艺对原水中的持久性有机物都有较好的去除效果，其中活性炭工艺要优于强化过滤工艺。Although the water quality of the Yangtze River in Nanjing section can remain in class Ⅱ ~ Ⅲ, toluene, trichlorobenzene and dibutyl phthalate can be detected in the raw water;that is to say Nanjing section of the Yangtze River source water has been shown micro-polluted characteristics. In order to improve water quality,species of persistent organic pollutants and specific organic pollutants （atrazine and chlorobenzene compounds）were studied. At the same time the abilities of enhanced filter and carbon filter to remove biological pollutants in Yangtze River water were investigated. The results show that there＆#39;re 65 kinds of persistent organic compounds in Nanjing Yangtze River source water,most of which are aliphatic hydrocarbons,aromatic organic compounds,organic esters,alcohols and ketones. These 5 kinds of organic matter reach more than 90% of the total amount of persistent organic matter;atrazine is not detected in Nanjing section of the Yangtze River source water. However 1,2,4-trichlorobenzene is 0. 249 μg/L. Enhanced filter and activated carbon filter process both have good removal efficiency. Activated carbon process is superior to enhanced filter process.
