The invention relates to the technical field of microbial fermentation, and specifically discloses a sludge aerobic composting compound bacterial agent and a preparation method and application thereof. The compound bacterial agent includes Paenibacillus barrenii TZ-1, Bacillus licheniformis TD-4 and Geobacillus thermodenitrifying HX-4. The sludge aerobic composting compound bacterial agent provided by the present invention is used for sludge composting, and has the advantages of fast heating rate, long maintenance time in high temperature period, high fermentation temperature, fast decomposing rate, high organic matter degradation rate, fast decrease of water content and high seed germination index. It can significantly shorten the composting cycle and improve the composting quality. |
