摘　　要：基于水体中的溶解氧(DO)会因为紫外光的存在参与到反应中并且产生1O2,O2.-和H2O2等活性物种(ROS),从而间接敏化提高废水处理效率。据此建立起紫外光协同次氯酸钠氧化法降解双甘膦废水中亚氨基二乙腈的方法。考察了次氯酸钠用量,pH,氧化照射时间,原料投加方式及不同光源对双甘膦废水处理效率的影响。结果表明利用紫外光协同次氯酸钠氧化法,亚氨基二乙腈的降解率达到95.1%,进一步可见有必要广泛推广,并在实用中进一步完善,以保持社会经济可持续发展的良性循环。Dissolved oxygen in the water which can produce reactive oxygen species such as IO2, 025 and H202 is able to sensitize and improve efficiency of treating wastewater. Based on this fact, a new oxidation technique of sodium chlorate and UV is introduced for degrading iminodiacetic nitrile in the N-（Phosphonomethyl）iminodiacetic Acid wastewater. The amount of NaCIO, pH of the solution, time of oxidation, ways of adding raw and different light on the degradation efficiency were investigated. The results showed that the degradation efficiency of this way is up to 95.1%.
