浑河各河段水质随季节变化趋势及影响因素研究

以COD和氨氮为污染物浓度指标,分析浑河上游、大伙房水库库区、工业用水区、农业用水区等各河段污染物浓度随季节变化的趋势,探讨浑河水质的影响因素。其中,各河段普遍受河流季节水文变化特征影响,不同用水区还受污染物排放量、农业生产等因素影响。

Taking COD and ammonia nitrogen as pollutant concentration indexes,this paper analyzes the trend of pollutant concentration along with the seasons in the upper reaches of Hunhe River,Dahuofang reservoir area,industrial water use area,agricultural water use area and so on,and studies the influencing factors of Hunhe River water quality.Among them,each river section is generally affected by the characteristics of seasonal hydrological changes of rivers,and different water-using areas are also affected by pollutants discharge,agricultural production and other factors.
