多水源供水管网余氯浓度优化调度

Optimal Operation of Residual Chlorine Concentration in Multi-Source Water Distribution System

目前建立的基于管网水力模型的水质计算模型都是静态的,即假定管网中各传输单元的余氯衰减系数固定不变,这对多水源管网且各水厂出水余氯浓度差异较大的管网系统是不适用的.通过建立符合实际工况的多水源水质计算模型,运用遗传算法求解,得到在满足供水管网余氯浓度要求的前提下各水厂出水的优化余氯浓度值.将该模型应用于实际管网,为实际管网的水质调度提供了重要依据.

So far, the water quality model based on the hydraulic model is static which assumes that the decay parameters of the residual chlorine of the pipes to be constant. Therefore, the model is not fit for the multi-sources water distribution system whose chlorine decay parameters are different. This paper presents a new water quality model adaptable to the real network more, which is solved by the genetic algorithm, and the optimized result which satisfies the requirement of the residual chlorine concentration at each junction is obtained. The model is applied to the real network and obtains the valuable information on the water quality operation.
