摘　　要：为有效了解和掌握供水管网余氯衰减变化,确保用户水质安全,以天津市某区供水管网为研究对象,构建余氯衰减动力学模型,模拟管网水余氯衰减趋势。通过由管网总余氯衰减系数、管网主体水余氯衰减系数及管壁水余氯衰减系数确定模型中余氯衰减反应系数,得出余氯衰减模型。该模型系数校核分为两个方面,一方面校核管网主体水反应系数,最终确定为0.265 d^(-1);另一方面校核管壁水余氯衰减系数,该校核通过粒子群算法与建模软件EPANET2.0相结合进行,最终得出当迭代次数为100,粒子规模为30时,水质模拟效果最好。通过建立该区供水管网余氯衰减模型,可以实时监测水余氯衰减趋势,以便供水企业进行管网水质运行现状评估和辅助调度等维护管理工作。In order to understand and master the variation of residual chlorine attenuation in water sup-ply network and ensure the safety of water quality,a dynamic model of residual chlorine attenuation was established to simulate the decay trend of residual chlorine in water supply network of a district in Tianjin.The decay reaction coefficient of residual chlorine in the model was determined by the decay coefficient of total residual chlorine in the pipe network,the decay coefficient of residual chlorine in the main water of the pipe network and the decay coefficient of residual chlorine in the pipe wall water.The checking of the model coefficients can be divided into two aspects.On the one hand,the main water reaction coefficient of the pipe network is checked and determined to be O.265d^(-1);on the other hand,the attenuation coefficient of residual chlorine in the pipe wall is checked.The checking is made by combining particle swarm optimization with the modeling software EPANET2.0,and the water quality model is finally determined when the iteration number is 100 and the particle size is 30.The effect is the best.Through the establishment of residual chlorine decay model of water supply network in this area,the decay trend of residual chlorine can be monitored in real time,so that water supply enterprises can carry out water quality evaluation and auxiliary dispatching maintenance and management work.
