摘要
在国内外相关研究基础上,利用输出系数模型估算了2006-2009年赣江下游流域非点源污染负荷及各类非点源污染源的贡献率。结果表明,畜禽养殖、农业人口和耕地是赣江下游地区非点源污染负荷的主要来源,在TN贡献率方面畜禽养殖>耕地>农业人口,在TP贡献率方面畜禽养殖>农业人口>耕地。针对估算结果,分析了赣江下游地区畜禽养殖、农业人口和耕地形成非点源污染流失的原因,并据此提出建造化粪池等小型污水处理设施和人工湿地等相应的控制措施。
Based on the relevant researches at home and abroad,output coefficient model is used to estimate load and contribution of non-point source pollution in Ganjiang downstream from 2006 to 2009.The results show that,the livestock,the agricultural population and cultivated land is the main source of Ganjiang downstream nonpoint source pollution.TN contribution of livestock farming is greater than that of cultivated land which is greater than that of agricultural population.According to the estimation results,various causes of non-point pollution loss in Ganjiang downstream are analyzed,and corresponding control measures of building small-scale sewage treatment facilities and artificial wetland are put forward.
