摘　　要：碳酸氢根(HCO-3)是水中最常见的阴离子之一,能直接影响饮用水的水质,并对饮用水的典型净化工艺的效能和处理出水的水质稳定性产生影响。论文总结了天然水体中HCO-3的来源和存在形式,系统分析了其含量对管道寿命、饮用水水质稳定性、舒适健康性的意义,以及对混凝、消毒等水处理工艺净化过程和出水水质的影响,在此基础上进一步探讨了饮用水处理过程中HCO-3的适宜控制目标。论文内容可为水厂及供水管网中HCO-3的合理控制、供水安全的保障提供一定的参考。Bicarbonate radical(HCO-3)is one of the most common anions in water,which directly affects the water quality of drinking water.At the same time,it also affects the efficiency of the typical purification process and the water quality stability of the evolved effluent.Paper summarizes the origin and existence form of HCO-3 in natural water bodies,systematic analysis of its content on the pipeline life,the significance of drinking water quality stability,comfort,health,and for water treatment processes such as coagulation,disinfection purification process and the influence of water quality.On this basis,the suitable control target of HCO-3 in the process of water treatment is discussed.The content of this paper can provide some reference for the reasonable control of HCO-3 and the guarantee of water supply safety in water treatment plant and water supply network.
