摘要
通过对绛溪河简阳段水污染源调查评价,找出主要的污染源,并在水环境容量计算的基础上,提出水污染控制措施。调查结果表明:绛溪河流域简阳段最主要的污染源是场镇生活污染源,其次是农村生活污染源和农田径流,其等标污染负荷比分别为45.7%、28.7%和22.6%;该段COD_(cr)和氨氮的水环境容量分别为1 354 t/a和43 t/a,剩余环境容量分别为227 t/a和-149 t/a。因此,应加强污水处理设施和生态河道的建设,大力发展生态农业。
Based on investigation of the water pollution sources in Jianyang section of Jiangxi River basin, main water pollution sources were found out. One - dimensional water quality model was used to calculate the water environmental capacity and control measures of water pollution were put forward. The results showed that the main water pollution sources were township domestic sewage, rural domestic sewage and farm runoff. Their equivalent standard pollution loading ratio was 45.7% , 28.7% and 22.6% , respective- ly. The water environmental capacity of CODor and NH3 - N was 1354 t/a and 43 t/a, respectively. And the surplus water environmen- tal capacity of CODer and NH3 - N was 227 t/a and - 149 t/a. Therefore, construction of municipal sewage treatment facilities and ec- ological river should be enhanced and ecological agriculture should be developed vigorously.
