摘　　要：针对南方某市地表水出现pH规律性升高而导致水厂出厂水中铝接近超标的问题,探索采用CO_(2)投加技术控制原水pH,使出厂水的铝含量符合GB 5749—2022《生活饮用水卫生标准》要求。相比传统投加化学试剂调节pH的方法,该方法更加安全、有效,符合水厂绿色、低碳的发展趋势。In response to the problem of the regularly rising pH of surface water in a southern city,which led to aluminum approaching the standard in the effluent of a water plant,we explored the use of CO2 addition technology to control the pH of raw water,so that the aluminum content in the effluent met the requirements of GB 5749—2022“Standards for drinking water quality”.Compared with traditional chemical reagent adjustment of pH,the method was more safer and effective,which accorded with the development trend of green and low-carbon in waterworks.
