辽宁省太子河水质现状及影响因素研究

对2015—2020年辽宁省太子河干流断面水质状况进行了统计分析,以氨氮、COD、总磷3项指标分析了太子河水质的沿程变化情况,结果表明,太子河中下游水质整体较差,且主要污染指标为氨氮。结合太子河流域的自然社会属性,支流河水质较差及农业农村污染较重导致这种水质状况,并在此基础上提出了太子河流域水质改善的措施建议。

The water quality of the main stream cross-section of the Taizihe River in Liaoning Province from 2015 to2020 was analyzed.The changes along the main stream of Taizihe River were analyzed by using ammonia nitrogen,COD and total phosphorus as the key analytical indicators.The results show that the water quality of the middle and lower reaches of the Taizihe River is relatively poor.The main pollution indicator is ammonia nitrogen.Combined with the natural and social attributes of the Taizihe river basin,the poor quality of water in tributary rivers and the heavy pollution in agriculture and rural areas are the main reasons.Based on these,suggestions and measures for improving the water quality of the Taizihe river basin are presented.
