河道水环境容量及污染负荷削减量的核算

Calculation of River Water Environment Capacity and Reduction Amount of Pollution Load

要治理河道污染,除掌握河道污染现状和污染源等基本信息外,还须明确河道的水环境容量,进而确定污染负荷削减量。本文结合实际案例,采用零维水质模型对河道水环境容量进行核算分析,最终确定了水环境容量和污染负荷削减量,并根据现状污染负荷数据分析了河道污染源、污染物结构类型。在科学构建模型和合理选择参数前提下,可计算得到合理的水环境容量及污染物负荷削减量,为河道治理提出针对性建议,也为下一步河道的工程治理提供数据支撑。

In order to control the pollution of river channel, in addition to basic information such as riverpollution status and pollution sources, the water environment capacity of river channel must be clearly de-fined to determine the reduction amount of pollution load. In this paper, based on the actual case, thezero-dimensional water quality model is used to calculate and analyze the river water environment capaci-ty, and finally the water environment capacity and the pollution load reduction amount are determined.Based on the current pollution load data, the river pollution sources and pollutant structure types are ana-lyzed. Under the premise of scientific model construction and reasonable parameters selection , the idealwater environment capacity and reduction amount of pollution load can be calculated, it not only providesthe targeted recommendations for river management, but also provides the data support for the next step ofriver engineering governance.
