细菌源追踪技术在杨家河水域枯水期的应用

The Application of Bacterial Source Tracing Technology in Yangjia River During Dry Season

随着各国政府对点源污染控制的重视,点源污染在许多国家已经得到了较好的控制和治理,而非点源污染由于涉及范围广,控制难度大,目前已成为影响水体环境质量的重要污染源。病原体(如粪大肠菌群、总大肠菌群)作为非点源污染的主要控制指标之一,具有非点源排放的显著特点。论文选取南四湖流域光府河支流杨家河段为研究对象,对研究对象枯水期进行取样分析,研究水体中大肠杆菌的种类与周边污染物的关系。

With the attention paid by many governments to point source pollution control, point source pollution has been well controlled in many countries. However, non-point source pollution has become an important source of pollution affecting the environmental quality of water bodies because it involves a wide range and is difficult to control. As one of the main control indicators of non-point source pollution, pathogens(such as fecal coliforms, total coliforms) have significant characteristics of non-point source emissions. Taking the section of Yangjia River, the branch of Guangfu River in Nansi Lake basin as the research object, this paper makes an analysis of the relationship between the species of escherichia coli in water and the surrounding pollutants through samples.
