摘要
通过分析工业区面源污染的来源和污染特征,针对工业区下垫面的特点,在分布式水文模型的基础上建立了工业区降雨径流面源污染模型.模型考虑了工业区大气降尘和地表污染物累积、地表污染物冲刷迁移转化、地表产流和径流挟带污染物在排雨水系统中的运移和汇流等面源产生、迁移主要过程.将建立的模型应用于某钢铁项目的厂区面源过程研究,取得了较好的效果.该模型可为工业区水环境规划、面源控制和管理研究提供科学手段.
Based on analyzing characteristics of the deposition flux and the ground surface,a distributed non-point source pollution model for industrial zones is developed.The model consists of the module of airborne dust deposition and accumulation,the module of rainfall-runoff,the module of runoff wash-off and the module of contaminated rainfall transport and convergence in the industrial drainage network.The model is applied to simulate the processes of rainfall run-off and non-point source generation in a typical iron and steel works.The study can provide the technique support for the water environmental planning,non-point source pollution control and management of industrial zones.
