Abstract

The invention discloses a calculation method for simulating river water quality parameters based on an SWMM model, and the method comprises the steps: building a river network model, and setting the transition section form of a river reach; inputting water quantity and water quality parameters into the corresponding modes for fitting; and characterizing the results of the water quantity and the water quality through the characteristics of the mode. According to the invention, the change degree of water quality in different time periods in a river channel can be simulated, and the water qualitysimulation module can be carried out through the synergistic effect of different pollutants; the water quality of inflow rivers in different areas can be simulated, the comprehensive sewage quality of the inflow riverway under the rain-sewage confluence situation can be simulated, and the rainwater quality of the inflow riverway under the rain-sewage diversion situation can also be simulated.

Description

technical field [0001] The invention relates to a calculation method for simulating river water quality parameters based on a SWMM model, which is suitable for the field of river water quality control in river basins and the field of river water quality simulation. Background technique [0002] SWMM is a powerful urban stormwater quantity, water quality, hydraulic prediction and management simulation model developed by the US Environmental Protection Agency (Environment Protection Agency, EPA) in Cincinnati, Ohio, in the 1970s. with forecasting software. [0003] The SWMM model is often used in the planning of urban rain and sewage pipe network, the design of urban flood control facilities, the design of natural channels, the application of LID facilities and sponge city measures in urban rainwater, and the calculation of urban non-point source pollution. [0004] In the process of treating black and odorous water bodies in my country, due to the hydraulic module and water ...
