摘　　要：基于非线性水库模型和霍顿入渗模型,对合流制系统进行有限差分演算,实现合流制溢流的动态模拟。采用模块化原则进行有限差分算法设计,通过输入模块预设合流制汇水区水文属性、调蓄池设计参数、气象数据等,利用模拟综合模块模拟汇水区产汇流、调蓄池入流和排空、截流系统溢流,使用统计模块划分降雨场次,统计场次溢流事件和溢流量。利用优化模块对不同调蓄规模的合流制系统进行动态模拟,绘制成本效益曲线,得出拐点规模,结合控制目标,优化调蓄池规模,从而为合流制溢流污染削减方案提供辅助设计方法和工具。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.
