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 x 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.
对苯胺的催化氧化进行了评估，为基于风险的使用芬顿试剂（催化过氧化氢）处理苯胺污染固体废物提供依据。研究了芬顿反应的操作条件，并分析了化学处理的影响因素。最佳条件如下：每克干燥固体废物加入1.1 mL过氧化氢，过氧化氢流速为0.5 - 1.0 mL·min⁻¹，在50克废物中于pH = 3.0时添加芬顿试剂两到三次，添加试剂后反应30分钟，苯胺去除率超过99.86%。此外，分析了固体废物中影响因素的作用机制；阐述了系统中反应的关键和控制步骤，为从稳定化、固化到填埋的进一步处理提供了保障。
