摘要
评估了广东省某河流上游入河排污口河水的水质,并给出SWOT分析和建议。监测的河流区域长80 km,在8个入河排污口采样点对河流水质进行监测和观察,采用污染指数法(IP)进行水质分析。根据对采样点BOD,COD和DO参数的实地测量,采样点的BOD,COD和DO都有超过地表水环境质量标准Ⅱ类水质标准的。同时,河流断面的IP值结果在4.93~5.0之间,处于轻度污染状态。在水污染防治方面,建议加强污水入河监测,开展水污染源头清查,确定污染负荷承载能力。
The main purpose of this study is to evaluate the water quality of effluent outfalls in the upper reaches of a river in Guangdong Province,and give a SWOT analysis and suggestions.The study area of the monitored river was 80 km long,and the river water quality was monitored and observed at 8 sampling points of the river outfalls.The pollution index method(IP)was used to analyze the river water quality.According to the field measurements of BOD,COD and DO parameters at the sampling points,the BOD,COD and DO of some sampling points exceeded the class II water quality standards of the Environmental Quality Standard for Surface Water.At the same time,the IP value of the river section is between 4.93 and 5.0,which is in a slightly polluted state.It is suggested to strengthen the monitoring of sewage into the river,carry out the source of water pollution inventory,and determine the carrying capacity of pollution load for prevention and control of water pollution.
