The invention relates to the field of microbial technology and environmental engineering, and discloses a novel kitchen waste high-temperature composting process assisted by a complex enzyme preparation and ochrobactrum. The preservation number of the Ochrobactrum anthropi is CGMCC No.19230, and the microorganism is named as Ochrobactrum sp. The complex enzyme preparation and the bacterial strain of the invention can be used for high-temperature aerobic composting treatment of various organic matters such as kitchen garbage, agricultural product tailings, slaughterhouse wastes and the like by matching with a high-temperature composting process, so that the organic matters are completely humified, dehydrated and dried, and reduced by 70-92%, and finally the organic fertilizer with excellent quality is formed. The novel high-temperature composting process also relates to special pretreatment means such as physical cutting, enzymatic hydrolysis, rapid heat generation of bacterial strain metabolism and the like, so that the compost can be rapidly heated to above 70 ℃ within 8 hours, the high-temperature stage of composting is rapidly entered, various high-temperature strains are rapidly changed into absolute dominant strains in a compost system, and on the basis of the absolute dominant strains, the semi-continuous composting fermentation process capable of feeding and discharging materials every day is realized. |
