- 摘要:由于农药的环境持久性及毒性,饮用水源中的农药微污染日益受到水处理行业的关注.在众多水处理工艺中,紫外光及基于紫外光的高级氧化工艺因其灭菌效率高、产生消毒副产物少等特点受到广泛关注.本文综述了紫外光及其相关高级氧化工艺对多类广泛使用的农药(包括有机氯、有机磷、氨基甲酸酯、氯乙酰胺和三嗪等)的降解效果,详细讨论了农药的降解效率、反应动力学、降解副产物的分析鉴定及可能的反应途径,并评估了降解副产物的毒性.
- Abstract:The micro-contamination of drinking water resources with pesticides is of great concern nowadays due to their persistence in the aquatic environment and potential adverse effects to human health. Among various water treatment processes,UVand UV-based advanced oxidation processes (AOPs) have gained great attention due to their effectiveness in bacteria inactivation and low yield of disinfection byproducts. This work reviews,in a comprehensive manner,the degradation of several classes of pesticides including organochlorines,organophosphates,carbamates,chloroacetamides and triazines by UVand UV-based AOPs. The degree of pesticide removal,reaction kinetics,degradation byproduct identification and possible degradation pathways,and evaluation of toxicity of degradation byproducts are covered and discussed.
