Abstract

The invention discloses a rural non-point source pollution simulation method based on an SWMM, and belongs to the field of non-point source pollution simulation. The method comprises the following steps: S1, data collection, S2, sub catchment area division and pipe network generalization, S3, underlying surface information acquisition, S4, model establishment and parameter selection, S5, water collecting well external inflow estimation and parameter setting, and S6, simulation execution, simulation result display and analysis. The rural non-point source pollution simulation method based on theSWMM is more scientific and reasonable. A new method for simulating non-point source pollution in rural areas is provided. The method is based on the actual demand of rural area non-point source pollution control and the demand of non-point source pollution simulation research development. The developed research on rural area non-point source pollution simulation has multiple meanings, the simulation result can provide a scientific basis for formulation of a pollution control strategy, and sufficient pollution emission information is provided for selection of production and living activitiesin the area.

Description

technical field [0001] The invention relates to the field of non-point source pollution simulation, in particular to a rural non-point source pollution simulation method based on SWMM. Background technique [0002] At present, the penetration rate of the pipe network in most rural areas is not high, and the random discharge of agricultural sewage and domestic sewage has caused the pollution of the surrounding water bodies. It poses a serious threat to the safety of people's lives and property. Therefore, the simulation and control of rural non-point source pollution is not only the inevitable result of the development of environmental science, but also an urgent need for social security. The SWMM model is the Storm Water Management Model, which comprehensively considers the various hydrological processes of runoff formation, and can simultaneously simulate the hydraulic and water quality conditions of surface runoff, and has been widely used in the field of runoff simulatio...
