摘　　要：应用多介质逸度模型(LevelⅢ)研究点源排放的五氯酚在水环境中的迁移转化规律,选择的水体为天津市污灌区。使用Metlab软件计算出五氯酚排放量为200.5 mol/h的点源,五氯酚在大气、水、土壤和沉积物的平衡浓度分别为:0.007 5 ng/L、0.092μg/L、25.30μg/kg、25.30μg/kg。结果表明,五氯酚绝大部分存在于土壤和沉积物中,这与五氯酚在环境中迁移的趋势一致,绝大部分存在于土壤和沉积物,水占很少一部分,大气中基本没有。Multi - Medium Fugacity Model is used to study the transfer and transformation principle of Pentachlorophenol of point source emission in water. Wastewaterirrigated area in Tianjin is selected as a fugacity model. Metlab software is used to calculate the balanced concentration of pentachlorophenol in the environmental phase, including four main phases of air, water, soil and sediment, which are respectively 0. 007 5 ng/L, 0. 092μg/L, 25.30 μg/kg and 25.30 μg/kg. It is found that the majority of pentachlorophenol exists in soil and sediment. Some cases are cited to testify the result.
