研究了我国某海岛地区以淡化水与地表水联合供水时,城市管网的水质变化情况,对比分析了淡化水与地表水的化学稳定性情况,考察了浊度、Cl-和总铁含量等主要参数在管网内的变化规律。结果表明,虽然淡化水其化学稳定性较差,但在优质管网中完全能够满足城市供水水质要求;联合供水地区城市管网水质与管道属性和停留时间存在较大关系,这与普通供水地区城市管网情况基本类似。
The water quality of urban pipe network was analyzed when the water supply of desalinated water and surface water was combined in an island region of China. The chemical stability of desalinated water and surface water was compared and analyzed. The turbidity, Cl- and total iron content The main parameters in the pipe network changes. The results show that although desalinated water has poor chemical stability, it can fully satisfy the urban water quality requirements in the high-quality pipe network. The water quality of urban pipe network in the joint water supply area has a great relationship with the pipe properties and the residence time, Urban pipe network situation is similar.
