摘要: 建立以EDTA钠铁作为催化剂的改进型Fenton氧化体系，研究改进型Fenton氧化处理含高浓度苯酚危险废物的影响因素、处理效果和控制参数。研究结果表明，针对含苯酚污染土壤的自配样，当EDTA钠铁投加量为2 μmol/g，15%H2O2投加量为0.1 mL/g，体系含水率为33%左右，反应时间60 min时，苯酚（含量为2 mg/g）的氧化降解率可达90%以上，反应后的体系pH约为5.7，便于直接进行固化稳定化等后续处理。该处理过程较传统型Fenton体系温和、安全，且适用于中性pH的体系，可应用于高苯酚含量且以固相无机质为主体的危险废物的快速应急处理。

Abstract: A modified Fenton reagent system was founded with sodium iron EDTA as a catalyzer, and influencing factors, effects and control parameters of decontamination of soil containing phenol by this modified Fenton reagent were studied. The results showed that the removal efficiency of phenol (initial content is 2 mg/g) in soil was over 90% under optimal operating conditions: 30% H2O2 of 0.05 mg/g, sodium iron EDTA of 2 μmol/g,system moisture content of 33%, and reaction time of 1 h. The ending pH value of soil was about 5.70. It makes the later treatment much easier. The process could oxidize high content of phenol contained in hazardous waste quickly, safely and efficiently.
