摘　　要：供水管网中的余氯浓度指示供水管网水质安全状况,手动或者在线仪表检测余氯浓度,都不能全面地动态地反应整个管网余氯的变化规律.在供水管网数字化水力模型基础上,运用拉格朗日动态水质算法对中国南方某市管网余氯量进行了仿真计算,并采用分布式并行遗传算法对水质模型参数进行了校核,最后模拟的结果和现场实测结果非常吻合.这表明,经过校核的水质模型具有一定的工程应用价值.Residual chlorine concentration is an important criteria to indicate the water quality safe condition in WDN(water distribution networks).Detection of residual chlorine concentration by manual and on-line meters can't generally and dynamically indicate the reaction rule of residual chlorine in the whole WDN.Lagrange dynamic algorithm is used to simulate the residual chlorine concentration in the WDN of a city in south China.The distributed parallel GA algorithm is taken to calibrate the water quality model.The result is in accordance with the field test result.It proves that the calibrated water quality model is a useful tool to large-scale application.
