里下河平原集聚式农村地表水特征污染物的时间和空间分布

Temporal and spatial distribution of characteristic pollutants in rural surface water of Lixiahe plain

以里下河平原某一典型性聚集式农村为例,通过对农村特征污染物总磷、氨氮、化学需氧量指标的分析研究,获取其在节假日期间和闲暇时间的污染状况水平以及经过该村落的主要河流的不同断面的水质状况。通过对其时间和空间的水质状况的调查为其提供其特征污染物控制的数据来源,并以此来推进新农村新形势下的农村污染防控。

At the present stage,taking a typical rural area of Lixia river plain as an example,through the analysis and study of the indexes of total phosphorus,ammonia nitrogen and chemical oxygen demand of rural characteristic pollutants,the pollution levels during holidays and leisure time and the water quality of the main rivers passing through the village in different sections are obtained.Through the investigation of its water quality in time and space,the data source of its characteristic pollutant control is provided to promote the prevention and control of rural pollution under the new rural situation.
