摘要
由于有机农药的过量施用使其成为水体介质中的重要污染物之一,对人类健康及环境构成了严重的威胁,因此水体中有机农药的降解备受关注,并且成为研究热点之一.本文分别对水体中的有机农药的生物降解、物理降解和化学降解等方面的研究进展进行综述,重点介绍了高级氧化技术中的光催化技术在农药降解领域的应用,概述了二氧化钛和溴氧化铋对有机农药光催化降解的基本原理,并展望了有机农药光催化降解研究趋势.
Organic pesticide became one of the most important contaminants in water due to their excessive application;and it has been widely attention for threat to environment and human health.This paper presents a review of the treatment technologies of pesticide in water,including biodegradation,physical degradation and chemical degradation.It is mainly summarized the application of photocatalysis in pesticide degradation,and summarized the basic principles of advanced oxidation technology using TiO2,bismuth oxide bromide photocatalystic system from pesticides degradation.Moreover,it is previewed the research tendency of photodegradation of pesticides.
