摘      要：Biostabilization is a cost-effective method for the beneficial utilization of sewage ***,during the operation of sludge biostabilization,some microbial species could be released into the atmospheric environment from the solid-phase of sludge easily and present a high risk to human *** study aimed to evaluate the risk of bioaerosol during sludge *** found a total of nine bacterial phyla,one archaeal phylum,and two fungal phyla in the bioaerosol *** them,Proteobacteria,Actinobacteria,Bacteroidetes,and Ascomycota were the dominant *** addition,the bioaerosolization indexes(BI)of prokaryotic phyla and flingal phyla ranged 0-45 and 0-487,*** ilia y Pseudarthrobacter,Pseudomonas,Tremellales spp.,and Fusarium were the preferentially aerosolized microbial genera with maximum bioaerosolization indexes of 19962,10360,1802,3055,and *** bioaerosol concentration during the biostabilization ranged from 160 to 1440 cell/m^(3),and we identified species such as Stenotrophomonas rhizophila and Fusarium graminerum with high bioaerosolization indexes that could be threats to human ***,which belongs to archaeal phyla,had the highest biostabilization index in our *** also found that Pseudarthrobacter was the easiest to aerosolize during the sludge biostabilization process.
