通过自组装油烟装置模拟产生餐饮油烟，并利用颗粒活性炭进行油烟吸附，吸附量为700 mg/g。利用GC-MS、元素分析和红外光谱等确认活性炭吸附有机物主要成分为小分子烷烃、烯烃和羰基化合物等。分别用臭氧、芬顿试剂和加热3种方法对吸附油烟后的活性炭进行再生。结果表明，臭氧法和芬顿试剂法再生后，活性炭的碘吸附值和COD值接近新鲜活性炭。从四氯化碳吸附率来看，芬顿试剂法的再生效果最好，再生率为81.3%。

Granule activated carbon (GAC) is used to adsorb simulated catering fume that is produced in a self-made fume device, and the adsorption capacity is 700 mg·g^-1.Main components of the fume adsorbed on the GAC are confirmed by GC-MS, elemental analysis and infrared spectroscopy, which compose of small molecular alkanes, alkenes and carbonyl compounds.Ozone, Fenton reagent and heating methods are respectively used to regenerate the GAC after adsorbing catering fume.Results show that the iodine adsorption value and COD value of GAC regenerated by ozone method and Fenton reagent method are close to that of fresh activated carbon.From the perspective of adsorption rate of the regenerated GAC to carbon tetrachloride, Fenton reagent method has the best regeneration effect, with a regeneration rate of 81.3%.
