The experiment of thermophilic aerobic fermentation of dead pigs was carried out with dead pigs as fermentation raw materials，maize stovers （T1），rape stovers （T2），sawdust （T3） and rice bran （T4） as additives，and dead pigs was fermented alone （CK） as control to explore the effects of different fermentation additives on the emission of main odor pollutants and the total odor intensity of main odor pollutants.In each experiment，totally 14 times sampling would be performed according to a fixed interval.The intervals were 3 hours and 6 hours from 0 to 6th hour and from 6th hour to 72th hour，respectively.Each sample was analyzed for odor pollutants and their concentrations were determined，along with the concentrations of ammonia and carbon dioxide.And multiple comparisons of total odor intensity of different treatments were conducted to determine the effects of additive types on total odor intensity during the thermophilic aerobic fermentation of dead pigs.Finally，the results showed：（1） A total of 40 odor pollutants were detected in 5 thermophilic aerobic fermentation tests for dead pig，18 of which could be accurately detected qualitatively and quantitatively，including 3 sulfur compounds，1 alkane compound，12 aromatic hydrocarbon compounds，1 phenolic compound and 1 inorganic compound.Among them，7 odor pollutants were identified as the main source of odor，including 3-ethyltoluene，4-ethyltoluene，p-cresol，methanethiol，dimethyl sulfide，dimethyl disulfide and ammonia.（2） Maize stovers，rape stovers and sawdust accelerated the process of thermophilic aerobic fermentation of dead pigs.Maize stovers increased the carbon dioxide emission，while rape stovers and sawdust reduced the carbon dioxide emission.（3） After adding different additives，the detected total odor intensity of emitted gas was different and the order of increase of the total odour intensity was T3，T2，T1，T4 and CK，suggesting that the use of additives could inhibit the odor emission to some extent，while sawdust had the best effect with the total odor intensity of 4 241.08.The above results showed that sawdust was the best additive for thermophilic aerobic fermentation of dead pigs.
