分析了一种新型截流式城市污水系统的运行机理及相关因素 ,建立了系统最优控制模型。研究结果表明 ,可以运用线性规划方法求得系统各分流室各时段内的最优流量分配 ,从而确定相应的最优控制状态。算例结果显示 ,所有时段内各分流室的最优控制状态与其位置及相应的污染度系数显著相关。研究成果对现有的或在建的截流式污水系统的有效运行有指导意义。
The operating mechanism and related factors of a new type of intercepting urban sewage system are analyzed, and the optimal control model of the system is established. The results show that linear programming can be used to find the optimal flow distribution in each distribution chamber of the system in order to determine the optimal control state. The results of numerical examples show that the optimal control conditions of the diversion chambers in all the time periods are significantly related to their location and corresponding pollution degree coefficients. The research results are instructive for the effective operation of the existing or under construction of a closure sewerage system.
