| 中文摘要 |
| 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0.5～1.0 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2～3次投加Fenton试剂，药剂投加完后继续反应30 min.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. |
| 英文摘要 |
| The catalytic oxidation of aniline was evaluated to provide the foundation for risk-based treatment of aniline-contaminated solid-waste using Fenton reagent (catalyzed hydrogen peroxide). The operating conditions of Fenton reaction were investigated and the factors of the chemical treatment were analyzed. The optimal conditions were following: 1.1 mL H２Ｏ２ per gram of dried solid waste, V(H２Ｏ２) 0.5～1.0 mL·min-1, addition of Fenton reagent twice or three times at pH=3.0 in 50 grams of waste, and the aniline removal rate is over 99.86% for 30 min reaction after reagent addition. Furthermore, mechanisms of affecting factors in solid-waste were analyzed; the key and controlling steps of reactions were expounded in the system, which provided safeguard for further treatment ranging from stabilization and solidification to landfill. |
