Abstract

The invention discloses an urban surface runoff pollutant load calculation method. According to the land utilization property of a catchment area and the condition of an underlying surface, a calculation model of the characteristic area of a permeable area, the characteristic area of an impermeable area and the characteristic area is provided, and a calculation model of the urban surface runoff pollutant load is established, so that the pollution load of various pollutants under the surface runoff under different rainfall conditions can be quickly estimated.

Description

technical field [0001] The invention relates to the field of urban water system engineering, in particular to a method for calculating the pollutant load of urban surface runoff. Background technique [0002] Non-point source pollution from urban runoff is the main cause of urban water quality deterioration. Analyzing the total amount of surface runoff pollutants under different rainfall intensities can provide a scientific basis for surface runoff pollution control and urban water environment governance. [0003] There is still a lack of a scientific, rapid and efficient method for estimating the total amount of pollutants accumulated in different sub-catchments within an urban area. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a method for calculating the pollutant load of urban surface runoff, which solves the engineering problem of estimating the total amount of pollutants accumulated i...
