摘要
对清溪河2014-2016年水环境进行调查与分析,单项水质参数评价为Ⅲ类,综合污染指数法评价为Ⅳ类。结果显示:清溪河入河污水509.71万t/a,入河COD 1707.17t/a,氨氮131.09t/a,总氮328.78t/a,总磷39.24t/a,其中COD、总磷主要来自畜禽养殖污染。最后,针对清溪河污染现状提出了治理建议。
The pollution sources of Qingxi river from 2014 to 2016 were investigated, indicating that 5.09×106 t/a of wastewater was discharged into this river, in which the COD, ammonia, TP were 1707.17 t/a, 131.09 t/a, 39.24 t/a, respectively. In addition, the COD and TP came primarily from livestock cultivation. The results showed that the water status were III class and IV class calculated by Single Water Quality Parameter Evaluation and Comprehensive Pollution Index Method Evaluation. Finally, some countermeasures were accordingly put forward based on the results.
