摘要： The influence of bulking agents on odor production in sludge composts was investigated. Three mixtures were composted over a 23-day period in aerobic composting tank using the same sludge with different bulking agent mixtures. Parameters monitored over this period included O-2, NH3, H2S, as well as VOCs. All mixtures had reached the faeces harmless standard by the bulking amount used. The type of bulking agent had little influence on NH3(p>0.05) and H2S(p=0.945) production. However, significant effect on VOCs concentration were found in the mixtures using different bulking agentsduringaerobic composting (p=0.006). VOCs production in Twcwas significantly higher than that of inTcs and Twc+cs, and no significant difference in Tcs and Twc+csmixtures(p=0.697). The sawdust and corn stalk using mixed would be the best bulking agent.
