| 摘 要： | 以两种典型内分泌干扰物(ECDs)——壬基酚(NP)和17α-乙炔基雌二醇(EE2)为目标物,运用GC/MS检测方法,对其在臭氧、臭氧/过氧化氢、臭氧/超声三种工艺中的去除特性进行了研究,并初步研究了臭氧降解的反应动力学。结果表明:联合工艺显著提高了目标物的去除效率,NP和EE2的去除率分别提高9.6%～17.7%和14.6%～23.4%。目标物去除率随臭氧投加量和pH值的增大而增大;随H2O2/O3摩尔比的增加先增大后减小,摩尔比为0.6时,去除率均达到最大;超声强化了臭氧氧化效率,但超声(US)强度(60～240 W)的变化对联合工艺去除目标物效果影响不明显。臭氧氧化两种目标物都遵循假一级反应动力学,碱性条件下的反应速率常数要大于酸性及加入叔丁醇条件下的反应速率常数。
