安宁河西昌段水质分析及评价

The Water Quality Analysis and Evaluation of the Anning River Xichang Segment

为了保障西昌市安宁河流域人民群众饮水安全和水资源可持续开发利用,了解安宁河西昌段水质污染程度及发展趋势,2009年对安宁河西昌段水质进行了统一标准监测,监测项目有BOD5、COD、PH、氨氮、色度、浊度、悬浮物、总硬度共8个项目。研究表明,安宁河西昌段的水质已由2005年的三类地表水环境质量变化为劣五类。总体上,该段内水质污染十分严重,并趋于上升,为保证安宁河整个流域的水质环境质量,提出了"地时制宜,健康发展,综合利用,资源共享"的综合措施。

To ensure the drinking water safety and the sustainable utilization of water resources for the people living along the Anning river of Xichang city,and to know the water pollution degree and its development trend of the Anning River Xichang segment,the united standard monitor was carried out to the Anning river Xichang segment in the year of 2009. The monitoring includes 8 projects-BOD5,COD,pH,NH3-N,colority,turbidity,suspended solid,total hardness. The experimental data proved the water quality of the Anning river Xichang segment has been worsened from the third class to the poor five class. Overall,the water of the segment is badly polluted and tends to get worsen. To ensure the water environment quality of the whole basin,the following comprehensive measures are put forward：Treatment in accordance with local and seasonal conditions,Healthy development,Comprehensive utilization,Resources sharing.
