摘要
卤代苯醌(HBQs)作为一类未受到管控的新兴消毒副产物,其浓度虽在ng/L级别,但细胞毒性和遗传毒性远高于常规的消毒副产物,水中HBQs类消毒副产物的控制对于保证饮用水水质安全具有重大意义。阐述了水体中HBQs类消毒副产物的浓度水平,综述了HBQs在水中的生成与转化,从前体物控制、过程控制、末端控制三个方面探讨了对HBQs的控制策略。提出了当前研究存在的不足,展望了未来对HBQs类消毒副产物研究的新方向和新思路。
As an emerging type of uncontrolled disinfection by-products,halobenzoquinones(HBQs)are more cytotoxic and genotoxic than conventional disinfection by-products at the ng/L level.The control of HBQs disinfection by-products is of great importance to ensure the safety of drinking water quality.The concentration levels of HBQs in water were described,the generation and transformation of HBQs were reviewed,and the control strategies for HBQs were discussed from three points of precursor control,process control and end-of-pipe control.The shortcomings of the current study were presented,the new directions and ideas for future research on HBQs disinfection by-products were foreseen.
