建立最优化的数学模型是污水处理系统规划的主要课题。本文开发了一个试探法与微分算法相结合的规划模型。该模型适用于由线性约束条件与非线性目标函数组成的污水处理系统——均匀处理、最优化处理与区域处理系统——的规划。相应的计算机程序可以输出水质约束方程的系数矩阵、污水处理与输送的费用,以及水体的水质参数。 本文通过算例说明了上述方法的应用,并对模型的灵敏度作出了分析。
The establishment of the optimal mathematical model is the main topic of the sewage treatment system planning. This paper develops a planning model that combines heuristic method and differential algorithm. The model is suitable for the planning of wastewater treatment systems consisting of linear constraints and non-linear objective functions - uniform treatment, optimization treatment and regional treatment system. The corresponding computer program can output the coefficient matrix of the water quality constraint equation, the cost of wastewater treatment and delivery, and the water quality parameters of the water body. In this paper, an example is given to illustrate the application of the above method and the sensitivity of the model is analyzed.
