Abstract: To study the effect of inoculating thermophilic bacteria into the chicken manure on the high temperature aerobic composting, two kinds of treatments, i.e.control experiment (CK, no bacteria added), and inoculation of three thermophilic bacterial strains culture mixture into the chicken manure, were designed, and the fermentation temperature, compost water content, pH value, NH₄⁺-N and organic matter amount were studied at different fermentation time. The results indicated that, compared with CK, the disposal inoculated with the mixed thermophilic bacteria raised the fermentation temperature quickly, with the highest temperature reaching 69℃; promoted the water vaporizing and accelerated the organic matter decomposing. At the same time, the compost pH value was 0.2 lower or more than that of the control. Furthermore, the seed germination index achieved 80.1% on the 17th day, which indicated that the compost reached the maturity state. The results showed that inoculation of thermophilic bacteria could deodorize the odor and prevent the NH3 from volatilization, and its concentration of NH₄⁺-N was 12.1% higher than that of CK.
