【摘要】 供水管网管壁铁不稳定引起的"黄水"问题是水务企业面临的运营难题之一,尤其是多水源切换及应用非常规水源水的情况下最为突出。供水管网"黄水"发生机理复杂,控制技术繁多。鉴于此,着重从铁稳定性的角度分析了"黄水"发生的机理,对比了各类机理的作用过程;考察了"黄水"发生的影响因素,并对各类因素的影响对象及影响浓度水平做了总结;调研了"黄水"控制技术,提出了各类技术的适用性,并对未来重点研究方向做了展望,为水务企业应对供水管网突发性"黄水"问题提供理论和技术参考。更多还原

【Abstract】 Red water release resulted from iron stability is a serious problem during the operation of drinking water distribution system. It was paid more attention in surroundings that the proportions of non-conventional and switching water sources are increasing. In the paper,emergency mechanisms and occurring processes of red water release were summarized. Additionally,the cause and influence parameters were analyzed by compare of the concentration levels. Moreover,measures for controlling red water were investigation and the application conditions of measures were discussed. Finally,to conduct the research on red water release was proposed.更多还原
