摘要
以西充河流域(西充县境内)的23个乡镇为例,采用输出系数法,从各个污染源和不同乡镇的角度出发,对西充县境内的农村面源污染进行了综合评价,并提出相应的防治措施。结果表明:研究区内的主要污染为农村面源污染:183.3%的污染负荷来源于为化肥污染、农村居民生活污水和散养畜禽;2虹溪河支流与龙滩河相比,污染较严重;3污染最严重的乡镇为晋城镇。根据评估结果,本文提出了相应的面源污染综合治理的工程及非工程措施和建议。
Taking for example the 23 towns,in Xichong River Basin(Xi-chong territory),the output coefficient method is used to evaluate the rural non-point source pollution comprehensively from the perspective of the various sources and different towns and put forward some corresponding control measures.The results show that the main pollution in the research area is the rural non-point source pollution:183.3% of the pollution load comes from chemical fertilizer pollution,rural residents living sewage and backyard poultry;2The pollution in Hong-xi River is more serious than Longtan River;3The most polluted village is Jin-cheng Town.According to the results of this evaluation,this paper puts forward the corresponding comprehensive control of non-point source pollution in engineering and non-engineering measures and suggestions.
