Abstract

The invention discloses a method for designing an initial rainwater storage tank in a plain city based on the characteristics of pollutants. The time corresponding to the maximum value of the pollutant accumulation rate in the pollutant accumulation process in the water catchment area corresponding to the plain urban storage tank is used as the time for the storage tank. The volume of the storage tank is designed based on the time point of interception of rainwater runoff and the process of cumulative runoff generated by the storage tank corresponding to the catchment area. Adopting the present invention to design the initial rainwater storage tank helps to provide the rationality of the design method of the initial rainwater storage tank, and can scientifically utilize the pollutant accumulation characteristics to design the volume of the storage tank, with a high interception rate and a certain increase Economical, to avoid unnecessary waste of manpower, material and financial resources.

Description

technical field [0001] The invention relates to the design field of initial rainwater storage tanks, in particular to a design method for initial rainwater storage tanks in plain cities based on the characteristics of pollutants. Background technique [0002] The non-point source pollution caused by urban rainwater runoff is the main reason for the deterioration of urban water quality. Setting up initial rainwater storage tanks is one of the most economical and effective means to solve rainwater runoff pollution. The initial rainwater is collected in the storage tank, and after the rainy season, it is discharged into the sewage treatment plant for treatment, and after the treatment reaches the standard, it is discharged into the nearby river. [0003] In urban areas, multiple initial rainwater storage tanks are usually set up according to land use patterns, drainage pipe network layout, location of sewage treatment plants and other conditions. The size of the initial rainw...
