- Abstract:
- Based on the nonlinear reservoir model and Horton infiltration model, the combined sewer overflow was simulated dynamically by using finite-difference algorithm for the combined system. The modular principle was adopted to design the finite-difference algorithm. Through the input module, the parameters were preset, including the catchment hydrological attributes, the design parameters of storage tank, meteorological data, etc. The integrated module was used to simulate the runoff of the catchment, the inflow and emptying of the storage tank, and the overflow of the intercepting system. The statistical module was used to divide the rainfall events and obtain the overflow events and overflows. By using the optimization module, the combined system with different storage volume was simulated dynamically. The cost-benefit curves were drawn. The volume at the inflection point was obtained, and the storage volume was optimized combined with the control objectives. Thus, it can provide an aided design method and tool for developing the reduction scheme of pollution resulted from the combined sewer overflow.
