摘要:

针对给水管网余氯质量浓度分布不均对管网水质造成较大的影响等问题,提出给水管网二次加氯2级优化动态模型,第1级是以满足管网余氯覆盖条件下加氯点数最少(即加氯点建设投资最少)为优化目标的加氯点选址优化模型,用余氯覆盖集表示加氯点对监测结点的水质影响程度.第2级提出基于理想余氯质量浓度的加氯速率优化模型,并结合算例对模型进行验证和分析.结果表明,该模型能够得到合理的加氯点选址方案和周期性加氯速率方案.二次加氯优化模型可以使管网余氯时空分布更为均匀且接近理想余氯质量浓度,同时可降低消毒剂投加量,从整体上改善管网水质.

Abstract:

An optimization model with two stages was proposed for the dynamic schedule of booster chlorination in a water distribution network(WDN)in order to decrease the variability of chlorine residuals. The first stage located the minimum number of booster stations (minimum construction cost) to supply enough chlorine residuals within a WDN, and the residual coverage set represented the impact of booster stations on monitoring nodes. Then the second stage determined the optimal chlorine injection rates based on the desired chlorine residual mass concentration. Numerical results show that the model can effectively obtain the reasonable locations of booster stations and the injection rate schedule. The model can decrease the variability of chlorine residuals and allow a lower chlorination dose, which improves the water quality in WDN.
