摘要
阐述水中卤乙酸(HAAs)去除方法。水中HAAs的去除方法包括物理、化学和生化方法。常规自来水处理工艺采用预氯化可以去除一定量的HAAs前体物质,但对预氯化产生的HAAs没有明显的去除效果。活性炭技术与生物降解技术是去除水中HAAs的重要手段。化学氧化方法(特别是涉及羟基自由基参与的高级氧化)是去除水中HAAs的一种可能途径。双金属协同与电化学的还原脱卤方法能够将HAAs脱卤生成不含卤素原子的乙酸,环境友好,可控性强,是一种很有应用前景的方法。
Various methods of haloacetic acids （HAAs） removal from drinking water were reviewed. The treatment methods of HAAs include the physical,chemical and biological approaches. The routine treatment process of tap water with prechlorination can remove some HAAs precursors,but little HAAs. Both activated carbon and biodegradation technology are important methods for the removal of HAAs. Chemical oxidation,especially the advanced oxidation processes characterized by the generation of hydroxyl radicals,is a potential method to HAAs removal. Reductive dehalogenation,including bimetallic synergy and electrochemical process,can change HAAs into acetic acid,and is a promising method for HAAs removal with controllable and environmentally desirable process.
