摘要
为了落实“十四五规划”对地表水环境质量的要求,为该河段今后的水环境管理提供理论依据和数据支撑,基于自动监测和手工采样监测数据,探讨河北某一河段水质现状,并结合河段周边污染源资料,进一步对该河段可能存在污染汇入的工业点源、农业面源进行排查,并对进入河道的主要污染源的污染负荷进行定量评估,通过核算河段污染物排放总量,进一步溯源解析了河段的污染物来源。结果表明:该河段COD和总氮均存在超标情况,该河段有污染物汇入的风险;主要污染来源为上游的污水处理厂排水。
In order to implement the requirements of the 14th Five-Year Plan for the environmental quality of surface water,aim to provide theoretical basis and data support for the future water environment management of the river section.Based on automatic monitoring and manual sampling monitoring data,the current situation of water quality in a certain section of Hebei was discussed,and combines the pollution source data around the river section,the industrial point sources and agricultural surface sources was further investigatedthat may have pollution in the river section,and the pollution load of the main pollution sources entering the river was quantitatively evaluated through the total amount of pollutant discharge in the river section was calculated,and the source of pollutants in the river section was further traced and analyzed.The results show that both COD and total nitrogen in the river section exceed the standard,and there is a risk of pollutant in the river section;the main source of pollution is the drainage of the upstream sewage treatment plant.
