永川区卫星湖氨氮、化学需氧量污染现状与控制对策分析

The Analysis of Pollution and Control Measures about Ammonia Nitrogen and BOD in the Yongchuan Wei-Xing Lake

文章简要介绍了卫星湖的自然环境,根据功能分区,在卫星湖设置5个监测断面分别在3月、9月、12月就生化需氧量,氨氮两项水质指标进行了检测分析。分析结果表明生化需氧量,氨氮两项指标均超过地表水Ⅲ类标准,调查显示产生的主要原因是农业面源污染,并针对农业面源控制提出相关的控制对策。

The paper described the natural environment of Wei-Xing lake,according to functional areas,five monitoring sections were set up in the lake,the two water quality indicators about BOD and ammonia nitrogen were analyzed in March,September and December.Analysis showed that BOD and ammonia nitrogen exceed the Class Ⅲ standard of surface water,survey showed that the main causes was the agricultural non-point source pollution and provided measures for the agricultural non-point source pollution.
