Abstract

The invention discloses a plain city primary rainwater regulating storage tank design method based on pollutant characteristics. The time corresponding to the maximum pollutant accumulative rates in the pollutant accumulating processes of water catchment areas corresponding to plain city regulating storage tanks serves as the rainwater runoff interception time points of the regulating storage tanks, and the volumes of the regulating storage tanks are designed by combining the runoff volume accumulating processes produced in the water catchment areas corresponding to the regulating storage tanks. By adopting the primary rainwater regulating storage tanks designed by the invention, the rationality of the design method for the primary rainwater regulating storage tanks can be provided easily,the volumes of the regulating storage tanks can be designed by scientifically utilizing pollutant accumulating characteristics, the sewage interception rate is high, the economical efficiency is alsoimproved to a certain extent, and unnecessary wasting of manpower, materials and financial resources is avoided.

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...
