A kitchen waste enterprise adopting bio-chemical processor treatment in Shanghai was selected as the research object. The odor pollution characteristics and key influencing factors of kitchen waste enterprises adopting aerobic biochemical processor treatment were deeply analyzed by screening the key test substances of the kitchen wastes, monitoring VOCs and odorous substances from the exhaust outlets of all treatment processes and the fugitive emission of factory area and boundary, and identifying typical odorous substances based on the evaluation of their odor activity value (OAV). The results showed that the concentration of VOCs and odorous substances was sorted as pretreatment workshop, biochemical workshop, and deep processing workshop from high to low, and the emission components were mainly organic substances such as alcohols, carbonyls, sulfides and aromatic hydrocarbons. The major odorous substances were sulfides such as ethyl mercaptan, butyl mercaptan, methyl mercaptan and ethyl sulfide. The wastewater treatment facilities were the main potential sources of odor, including the leakage of biogas in the anaerobic wastewater tank and the escape of fugitive odor from wastewater treatment facilities, etc. The surrounding odor pollution of the kitchen waste enterprise adopting aerobic biochemical treatment had a significant relationship with their production processes. It was suggested that enterprises of the same type could alleviate the odor pollution problem by reducing fugitive odor emission links, establishing regular biogas leakage detection and emergency management system, and improving the operation effect of deodorization devices.
