The invention discloses a rural household livestock and poultry manure composting technology mainly used in a low-temperature environment, and belongs to the technical field of environmental engineering. A technical treatment core is invention of a low-temperature livestock and poultry manure fermenting tank and composting compound bacteria. The low-temperature fermentation tank comprehensively considers functional requirements in the whole process from feeding of a composted material to final thoroughly decomposing, and has several main functions of sealing, preserving heat, heating, ventilating, stirring, discharging a leachate and discharging; the compound bacteria are microbial compound bacteria obtained by activating selected four cultures of bacillus subtilis, protease, pseudomonas and actinomycetes in a laboratory and blending according to a certain ratio. 本发明是，主要用于低温环境下农村家庭畜禽粪便堆肥技术，属于环境工程技术领域。技术处理核心是畜禽粪便低温发酵罐和堆肥复合菌的发明。低温发酵罐综合考虑从堆肥物料进料到最终腐熟整个过程功能要求，具备密闭、保温、加热、通风、搅拌、渗滤液排除、出料几项主要功能。复合菌在实验室内对选定的枯草芽孢菌、蛋白酶、
