摘　　要：以一亩泉河分支--保定市护城河为研究对象,通过分析其河段水质COD的各个采样点的变化规律,研究COD的变化对周围城市环境极其居民住宅的影响,检验城市臭水沟排放及周边城市环境对水质的影响。探究护城河水体的COD,采用重铬酸钾法国家标准构建方法模型并进行试验操作。根据护城河水质COD的数据分析为改善水质环境提供建议。In this paper,Baoding moat,a branch of the Yimuquan River,is taken as the research object.Through analyzing the change law of COD in each sampling point of its reach,the change of COD and the influence of surrounding urban environment and residential buildings are studied,and the influence of urban drainage ditch discharge and surrounding urban environment on water quality is examined.The COD of moat water was investigated,and the national standard potassium dichromate method was used to build the method model and carry out the experimental operation.According to the data analysis of water quality COD in moat,suggestions are provided for improving water quality env ironment.
