根据《化工建设项目环境保护工程设计标准》等相关标准规范的要求,化工厂区污染区域初期雨水需进行收集处理,防止通过企业雨水管网直接外排污染受纳水体。结合湖北省内化工项目实例,就初期雨水收集原则、收集方式、收集措施、初期雨水池容积计算、初期雨水池切换控制方式等方面,对化工厂区污染区域初期雨水收集系统的设计进行探讨,为相关实际工程设计提供参考。

Abstract:
According to relevant codes and standards such as Design Standards for Environmental protection Engineering of chemical construc- tion projects , initial rainwater in contaminated areas of chemical plants should be collected and treated to prevent direct discharge of polluted wa- ter through rainwater pipe network of chemical plants. Taking the case of chemical engineering projects in Hubei province as an eXample , the de- sign of initial rainwater collection system in polluted areas of chemical plantsis discussed in terms of initial rainwater collection principles , collec- tion methods , collection measures , volume calculation and control mode switching of primary rainwater pond and soon. It could provide reference for related practical engineering design.
