摘要
通过分析昆明捞鱼河国家湿地公园水质情况,以期对有效控制水体污染、改善水质等问题,提供理论参考。依据HJ 495-2009规定,于枯水期、丰水期(2021年04月、07月)在捞鱼河湿地公园布设不同采样点,对水体理化指标(pH、高锰酸盐指数、总磷、总氮、氨氮、硝酸盐氮、亚硝酸盐氮)采用GB/T 11892-1989、GB/T 11894-1989、GB/T 11893-89等方法进行测定;依据GB 3838-2002(国家环境保护总局2002)水质标准进行评价,结果表明:采样点枯水期、丰水期两季水质情况存在一定差异,各指标结果大多超过地表水Ⅴ类标准。
According to the water quality analysis of the Laoyu river national wetland park in Kunming,reference to control water pollution effectively and improve water quality is provided.Based on the regulations of HJ 495-2009,different sampling points were set up in the Laoyuhe wetland park during the dry season and the wet season(April and July 2021).The indices of pH,CODMn,TP,TN,NH_(3)-N,NO_(3)-N,NO_(2)-N were measured by GB/T 11892-1989,GB/T 11894-1989,GB/T 11893-89etc.The water quality was evaluated based on the standard evaluation of GB 3838-2002.The results showed that the water quality of different sampling points had some certain differences between the dry season and the wet season,and most of them exceeded the class V standard of surface water.
