多水源供水管网余氯浓度优化调度

Optimal Operation of Chlorine concentration in Multi-Source water distribution system

摘要:

供水管网中的余氯浓度指示了供水管网的安全状况，城镇供水管网上的在线余氯监测仪器数目很有限,无法反映整个管网中余氯浓度的分布情况。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供水水厂出厂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，得出在满足供水管网余氯浓度要求上的各水厂的优化余氯出厂浓度。将该模型应用于实际管网，为实际管网的水质调度提供了依据。

Abstract：The concentration of residual chlorine is an important factor indicates the water quality in drinking water distribution system. The monitoring equipments of the residual chlorine on the water distribution system are limited, so the general operational situation of the network can’t be reflected effectively. At present, the water quality model is static which is based on the hydraulic model. In the model, it assumes that the decay parameters of the residual chlorine of the pipes are assumed to be constant, so it is not fit for the multi-sources water distribution system whose chlorine decay parameters are different. In this paper, a new water quality model is established which corresponds with the real network more, solved by the Genetic Algorithm, and optimization result which satisfies the requirement of the residual chlorine concentration at each junction is obtained. The model is applied on the real network to obtain the valuable information on the water quality operation.
