摘　　要：通过模拟垃圾焚烧电厂内垃圾坑的实际条件,针对厌氧及好氧2种发酵方式进行了生活垃圾的生物干燥实验研究。结果表明:厌氧方式对生活垃圾的生物干燥效果不明显,自然厌氧发酵、接种厌氧发酵的垃圾脱水率均不超过5%;好氧方式对生活垃圾的生物干燥效果明显优于厌氧方式,在所研究条件下,通风量3.3×10-8m3/(s.kg)、发酵时间80 h的垃圾好氧生物干燥效果最佳,水分脱除率可达15.3%。Through simulating actual conditions of waste pit in waste incineration plants, aiming at anaerobic and aerobic fermentation, the bio-drying experimental study of domestic waste was carried out. The result showed that the anaerobic bio- drying effect of domestic waste is not obvious, waste dehydration rate is less than 5% by natural anaerobic fermentation and inoculating anaerobic fermentation. Aerobic bio-drying effect of domestic waste is obviously better than that of the anaerobic way. Under the research condition, dehydration rate of waste can reach 15. 3% with ventilation quantity of 3.3 × 10^-8 m^3/（s·kg） and fermentation time of 80 hours.
