本文把水库、河流与污水处理厂科学地合并为一个水污染控制的大系统,建立了水库和污水处理厂系统的多目标决策模型;通过把递阶分析与多目标优化相结合,用递阶动态规划求解;得出了水库峰荷发电量与污水处理费用、电力系统补充发电容量与污水处理费用的非劣解集;并求出了水库和污水处理厂系统在各非劣解下的运用过程。理论分析和实例验算证明了模型及其分析方法的可行性和通用性;为现有水利工程的合理利用和水环境保护提供了切实可行的分析途径。
In this paper, reservoirs, rivers and sewage treatment plants are scientifically integrated into a large-scale system of water pollution control and a multi-objective decision-making model for reservoirs and sewage treatment plant systems is established. By combining hierarchical analysis with multi-objective optimization, Dynamic planning and solving; obtained peak load power generation and sewage treatment costs, power generation capacity and sewage treatment fee non-defective solution set; and obtained the reservoir and sewage treatment plant system in each non-inferior solution process. Theoretical analysis and case verification prove the feasibility and universality of the model and its analytical methods. It provides a feasible analytical approach for the rational utilization of existing water conservancy projects and water environment protection.
