基于废活性炭纤维(activated carbon fiber,ACF)会对环境造成二次污染的问题,对介质阻挡放电(dielectric barrier discharge, DBD)臭氧发生器产生的臭氧(O3)处理负载对硝基苯酚(p-nitrophenol, PNP)的ACF进行了研究.考察了PNP负载量、废ACF湿基水的质量分数、O3质量浓度和处理时间对PNP降解率和臭氧利用效率的影响.结果表明,在PNP负载量为220.0 mg/g,废ACF湿基水的质量分数为15%,O3质量浓度为7.4 mg/L,处理时间60 min的实验条件下,PNP降解率高达88.8%.旨在探索一种经济高效的废ACF处理方法,以期为废ACF处理技术提供新思路和新方法.
