摘　　要：给水安全输配是保障饮用水水质的重要环节,对管网水质变化规律进行研究可为改善管网水质、建立水质模型提供基础数据。以天津市的给水管网为研究对象,沿水流路径开启消火栓放水进行测试,考察了余氯、浊度、TOC和三卤甲烷等主要水质参数在管网中的变化规律。结果表明,管道属性对水质有较大影响,并呈现出明显的规律性;为防止水质恶化,应定期排放管网末梢的死水。Water quality of the water distribution system is vital for maintaining safe drinking water. A research on the variation of water quality in water distribution system can improve drinking water quality, and provide data for building water quality model. The water quality of the Tianjin water distribution system was investigated by opening hydrants along the water flow path. Important water quality parameters including residual ehorine, turbidity, TOC and THMs are analyzed. The results show that the pipeline attribute has a significant effect on the water quality with obvious regularity. To prevent deterioration of water quality, remaining stagnant water in the pipeline system should be discharged periodically.
