The invention relates to the technical field of microbial agent sewage treatment, and discloses a fermentation microbial agent for urban domestic sludge fermentation deodorization and heavy metal passivation and a preparation method thereof.The fermentation microbial agent is prepared from, by mass, 8-15 parts of alcaligenes faecalis bacterial powder, 10-16 parts of halomonas bacterial powder, 20-40 parts of paracoccus faecalis bacterial powder, 20-30 parts of staphylococcus amber bacterial powder and 40-60 parts of carriers; and 2-5 parts of urea. According to the scheme, multiple microorganisms are used in a combined mode, odor substances generated in the urban domestic sludge fermentation process and heavy metal existing in the sludge are conveniently removed, the surrounding environment of an urban sewage plant is improved, the heavy metal can be effectively passivated, and green treatment of the sludge is achieved. 本发明涉及微生物菌剂污水处理技术领域，公开了一种用于城市生活污泥发酵除臭、重金属钝化的发酵菌剂及其制备方法，包括如下质量份数的原料：粪产碱杆菌菌粉8～15份，盐单胞菌菌粉10～16
