摘　　要：自行设计Fenton试剂法降解还原性气体异味的反应器,研究了Fenton试剂法处理餐厨垃圾异味主要成分(苯、乙酸乙酯、苯乙烯)的降解效果。以苯为典型代表物,优化得出该实验的最佳反应条件为:pH=3,FeSO4.7H2O投加量为1 g/L液相,30%H2O2投加量为10 mL/L液相,紫外光源辅助。结果证明,Fenton试剂法处理单一异味气体的效果较理想,在前180 min内能达到90%以上,该法在处理气态异味污染物方面具有广阔的应用前景。In order to reduce the odor in food waste facilities with the major components of benzene, ethyl acetate,styrene, Fenton reagent reactor was utilized in this process and corresponding parameters were optimized by single factor experiment. Benzene was chosen as the representative of food waste odor, and the parameters were determined as follows： pH of 3, the input amount of FeSO4 · 7H2O of 1 g/L liquid,the addition for 30% H2O2of I0 mL/L liquid,and the UV assisted as well. The results demonstrated that Fenton reagent method cou｜d reach a better effect on the degradation of a single odor with a removal efficiency more than 90% in the first 180 min. The method could have better prospects in dealing with the gaseous odor pollutants.
