摘要
Abstract
[Objective]It is in order to solve the non-poit source pollution casyed by initial rainwater to the rivers.[Methods]This paper takes the initial rainwater regulation and storage project of Moshui River in Jimo District as the research object,selected the appropriate collection and treatment mode starting from the initial rainwater's accurate separation and storage,analyzed the distribution rain pattern of the design storm course with the Chicago rain pattern,and systematically studied the initial rainwater's interception quantity and flow.The key technical points of the initial rainwater collection and treatment system,such as the process flow,initial rainwater separation device design,storage tank design and operation mode state,were introduced in order to provide reference experience and technical support for similar projects.[Results]The effect on the initial rainwater interception is obvious after the implementation of the project,chemical oxygen demand mass concentration reaches 300～800 mg/L,total nitrogen mass concentration reaches 2～8 mg/L,suspended solid mass concentration reaches 200～500 mg/L.[Conclusion]The project plays an important role in improving the water quality of the Moshui River from class Ⅴ to class Ⅳ.关键词
