摘　　要：针对保定市清水河、护城河、一亩泉河等河流进行COD值测定。经过测定,发现整体数据体现出西高东低的特点,尤其是西部郊区数值比较高,污染明显。市区护城河的污染水平相对较高,一亩泉河和府河的水质相对较好。分析主要污染源是生活污水的排放,未见工业污染,农业污染较少。河水流速低不利于污染物扩散,相对于2017年治理力度下降等因素也是造成保定市内河污染水平偏高的主要原因。结合污染情况,及保定市实际情况对河水的治理提出了初步建议。The COD values of Qingshui River,Moat River and Yimuquan River in Baoding City were measured.After measurement,it is found that the overall data reflect the characteristics that it is high in the West and low in the east.Especially in the western suburbs,the values are relatively high and the pollution is obvious.The pollution level of urban moat is relatively high,and the water quality of Yimuquan River and Fuhe River is relatively good.The main source of pollution is the discharge of domestic sewage.There is no industrial pollution and less agricultural pollution.Low river flow velocity is not conducive to pollutant diffusion.Compared with 2017,the reduction of control efforts and other factors are also the main reasons for the high level of pollution in Baoding inland river.Combined with the pollution situation and the actual situation of Baoding City,some preliminary suggestions for river water treatment are put forward.
