摘　　要：选择5种复合发酵菌剂添加到城市污泥中进行好氧发酵试验。结果表明:除添加菌剂1外的其它发酵物料温度保持在55℃以上的时间都满足堆肥国家卫生标准要求;接种复合菌剂的物料升温速率和温度最高值均大于未接种菌剂的处理,接种复合菌剂有利于加快堆体水分散失率,加快物料有机质降解速度,其中以菌剂2表现得最为明显。The effects of 5 microbial inoculants on aeration composting of sewage sludge were conducted. The results showed that the duration of high temperature above 55 ℃ almost conformed to the sanitary standard of the aerobic composting,except the microbial inoculant 2. The temperatures of those treatments with inoculation were higher than that of the treatment without inoculation and the inoculation treatments was proved to be effective in the reduction of the moisture,accelerating the decomposition of organic matters,decreasing the nitrogen loss and improvement of the composting maturity. Through the composting,we can find that the microbial inoculant 2 may be one of the best candidates as microbe inoculants.
