用CO2代替酸是中和各种碱性水的安全、有效和经济的方法。CO2在水中溶解时，发生了一系列的化学反应，减小了pH值。CO2使用在水处理的许多领域中，其中包括废水处理、工艺水pH值控制和饮用水的二次增碳。当用于控制州值大小时，省去了现场的酸的存储和运输，CO2有效地降低了设 The use of CO2 instead of acid is a safe, effective, and economical method of neutralizing various alkaline waters. When CO2 is dissolved in water, a series of chemical reactions take place and the pH is reduced. CO2 is used in many areas of water treatment, including wastewater treatment, pH control of process water, and secondary carbon addition of drinking water. When used to control the size of the state, the on-site storage and transportation of acid is eliminated, and CO2 is effectively reduced
