Design of Full Underground Type of Initial Rainwater Storage Tank for a Drainage Pumping Station
With the continuous development of economy and society at home,the urban non-point source pollution load is increasing year by year,which has seriously threatened the water environment quality of regional rivers and lakes.It is an important measure to control runoff pollution and improve regional water environment to set initial rainwater storage tank at the end of drainage system.Combined with an example of the design of underground initial rainwater storage tank for a drainage pumping station in Shanghai City,the paper demonstrates and analyzes the land area,economic investment,management and maintenance,according to the construction type,operation mode,process selection,etc.The optimum design scheme of the main process parameters of the initial rainwater storage tank is introduced,which can provide reference for application of underground initial rainwater storage tank for a drainage pumping station.
