摘要
管网安全供水是指在出厂水质合格并具有足够水量和压力的前提下以尽可能低的造价,同时满足用户在水质、水量及水压三方面的要求。符合水质标准的出厂水,经管网输送给用户后,水质常常会发生恶化。该文主要从出厂水水质、管网管材、二次供水设施、管网水力运行情况及加氯消毒等方面分析了造成水质恶化的原因,并有针对性地提出了改善管网水质的多项措施和方法。
The safety water supply distribution system means that the finished water can meet the users’ need from the water quality,water quantity and water pressure at the same time.However,the finished water which has accorded with the water quality calibration is deteriorated after transiting through the water distribution system. In this text,it analysed the reasons of water quality deterioration in water distribution networks from finished water quality,pipe material,secondary water supply estabishment,hydraulic operation and chlorine disinfection.At last some corresponding methods and measures were proposed to improve the distribution system water quality.
