摘要
烯啶虫胺作为一种新烟碱类杀虫剂使用越来越广泛,其危害性和生态安全风险也逐渐被重视.研究表明,施用的烯啶虫胺会进入土壤污染地下水,进入水体后在鱼类和贝类体内蓄积危害人类健康,存在遗传毒性,对蜜蜂、家蚕、蚯蚓等危害较大.虽然烯啶虫胺在自然水体中能够发生水解和光解,存在时间较短,但是降解产物的毒性和环境稳定性高于烯啶虫胺,可能引发更严重的水污染问题.因此,学者开始关注水中烯啶虫胺的处理方法研究,已有微生物处理法、树脂吸附法、电化学氧化法、光解法、生态处理法等被报道.其中,好氧微生物处理法效果差,树脂吸附法产生二次污染,生态处理法受到自然因素影响大,电化学氧化法不但处理效果好,而且可控性强,在实际的烯啶虫胺等杀虫剂废水的处理中具有广阔的应用前景.
Nitenpyram has been more and more widely used as a new kind of neonicotinoid insecticides,so that its harmfulness and the ecological safety risk is being increasingly considered.Research has shown that its widespread application can contaminate the soil and groundwater,which will be accumulated in the body of the fish and shellfish and harm to human health,have genetic toxicity to bees,silkworm,earthworms.Although its persistance is poor in the natural water because of hydrolysis and photolysis,but the toxicity and environmental stability of the degradation product is higher than itself.In fact,its natural degradation could lead to more serious water pollution.Therefore,more and more scholars begin to pay closely attention to the research of Nitenpyram contaminative water treatment.Many methods were reported such as aerobic microbial treatment,resin adsorption method,electrochemical oxidation,photolysis method,ecological treatment method.All of them,the treatment effect of aerobic microbial is poor,resin adsorption method produce secondary pollution,and ecological process is easily affected by natural factors.However,electrochemical oxidation treatment effect and controllability are better than others,which has shown potential applications in pesticide wastewater treatment.
