摘要
选取2010年武烈河6个监测断面的水质监测数据作为研究对象,采用贝叶斯公式对其水质进行综合分析评价,结果表明:各监测断面水质评价均在Ⅲ类以上,总体水质结果较好,符合水功能区划要求;66.7%的断面达到Ⅰ类,包括高寺台上游、双峰寺水库坝址、雹神庙和污水处理厂出水口下游4个断面;高寺台下游断面只达到Ⅲ级,主要是由于高寺台镇及其矿区生活污水和农业退水未经处理直接排入河道造成的。为保障双峰寺水库运行后的流域水环境质量和供水安全,需从水源地建设、点源治理和面源治理3个方面采取水环境保护措施。
The Bayes method is used to analyze and evaluate the water quality of the Wulie River based on the observed data at six monitoring sections in 2010. The result shows that the water quality for all sections is above Class III, resulting in an overall good water quality which meets the requirement for the water function zoning. Furthermore, 66. 7% of all the sections have the water quality reaching Class I, including the upstream of Gaositai, the Shuangfengsi reservoir dam site, the Baoshenmiao,and the downstream of sewage treatment works outlet. The water quality at the downstream of Gaositai only reaches Class III, which is due to the effects of domestic wastewater from Gaositai town and its mining area, and the agricultural drainage water discharged into the river without treatment. In order to ensure the water quality and water supply in the river basin after the Shuangfengsi reservoir operation, it is necessary to employ the waterenvironment protection measures from three aspects, including water re source construction,control on point source pollution,and control on nonpoint source pollution.
