摘　　要：二氧化碳液投加系统是一种高效且环保的水处理解决方案,它通过将预反应生成的碳酸直接注入待处理的水中,利用碳酸与碱的迅速化学反应,有效降低水的pH值。根据二氧化碳投加系统的核心原理和特点,对其应用于净水工艺中强化混凝、控制消毒副产物、再矿化等进行描述,并对实际应用案例中,碳酸溶液投加系统、液态气体储罐液态转气态进行了说明介绍。The CO_(2)solution dosage system is an efficient and environmentally friendly water treat-ment solution.It involves injecting carbonic acid generated from a pre-reaction directly into the water to be treated,utilizing the rapid chemical reaction between carbonic acid and alkali to effectively lower the pH of the water.Describing the core principles and characteristics of the carbon dioxide injection system,this text discusses its application in water purification processes such as enhancing coagulation,control-ling disinfection by-products,and remineralization.It also explains the application of the carbonic acid solution injection system and the conversion of liquid gas from storage tanks to gas in practical case stud-ies.
