摘　　要：为了研究镇江合流制管网受纳水体污染状况,对古运河市区段5个主要断面进行监测,在水环境评价预测的基础上,利用单因子评价法,以对水体环境质量影响较大的CODCr、BOD5、TP、NH3-N作为评价因子,以地表水环境质量标准为依据,研究受纳水体污染程度,对地表水环境质量予以分级。结果显示,镇江市古运河监测断面在平水期、丰水期和枯水期水体均为V类,主要污染物为CODCr、BOD5、TP和NH3-N。To research pollution condition of receiving waterbody for Combined Sewer System in ZhenJiang.Five main spots along the ancient canal cross the city are monitored.on the base of water environment evaluation,single factor assessment is used to evaluate water environment.This paper selects CODCr,BOD5,TP,NH3-N as evaluation factors,which have greater influence on the environment,according to the category gradation of environmental quality standard,We can carry out environmental quality and pollution degree.The evaluation results show that the water quality of the five spots is level V,no matter during dry period,wet period and level period.The main polluants are CODCr,BOD5,TP and NH3-N.
