北海市冯家江水质监测与评价
|
摘要
为了解冯家江水质状况,通过对溶解氧、氨氮、pH、高锰酸盐指数、五日生化需氧量、水温等指标监测,并以《地表水环境质量标准》(GB3838-2002)为依据,采用单项污染指数法和综合污染指数法对其污染程度进行评价。结果表明,从单因子污染指数评价可知冯家江水体污染严重,特别是氨氮和五日生化需氧量严重超出Ⅲ类地表水水质限值,从综合污染指数等级也可知冯家江水体污染严重,从污染程度看上游大于下游,应重视上游污染源监测与防治,以改善水质。
In order to understand Fengjia jiang water quality, the dissolved oxygen, ammonia nitrogen, pH, permanganate index,BOD five, water temperature and other indicators for monitoring, and the "environmental quality standards for surface water(GB3838> 2002) as the basis, to assess the degree of pollution by using the single pollution index and comprehensive pollution index method.The surface, from the single factor pollution index shows that Feng Jia Jiang serious water pollution, especially ammonia nitrogen and BOD five seriously exceeded the class III of surface water quality limits, from the level of comprehensive pollution index also shows the degree of pollution on the tour more than Feng Jia Jiang downstream, should pay attention to the monitoring and control of the upstream sources of pollution, to improve water quality.
