城乡统筹供水管网水质控制优化调度研究

Research on optimal control of water quality in urban and rural integrated water supply system

结合实验室数据校核得出适合研究区域内的城乡统筹供水管网水质模型,基于水质模型建立并求解了余氯优化调度模型,开发了在线水质模拟和优化调度管理平台。通过水质优化调度研究,在保障管网中各节点余氯量满足国家规范要求下,相比人工氯投加量下降了20.5%;最后从工程性措施提出了乡镇管网水质改善的建议。

The urban and rural water quality models for pilot city,including residual chlorine and disinfection by-products,are built and calibrated combined with laboratory data,and the residual chlorine optimal control model is established based on water quality model,and the online water quality simulation and optimal control management platform is developed.Through this research,under the requirements of residual chlorine of national regulations,the amount of chlorine injection to network is reduced by 20.5% compared with original chlorine injection.Finally,the suggestions for improving water quality in rural water distribution system are proposed from the aspect of engineering measures.
