摘要：

研究了Fenton催化氧化法对工业固体废渣中苯胺的去除效能,优化了其在固相处理体系中的反应条件,并分析了各影响因子的作用机理和综合反应机理及应用的关键控制步骤.结果表明,在固相反应体系中,采用Fenton催化氧化法处理工业固体废渣中苯胺的最佳反应条件为:pH值3.0,50 g渣样中H2O2流加速率为0.51.0 mL.min-1,30%H2O2投加量为1.1 mL.g-1(以干渣计,下同),Fe2+的投加量为0.012 mmol.g-1(以干渣计,下同),分23次投加Fenton试剂,药剂投加完后继续反应30min.在此条件下固体废物中苯胺的去除率达99.86%,从而为后续的稳定化及固化处理和进入安全填埋场进行安全填埋处理提供了前提保障.
