The invention discloses a preparation method of a composite bacterial agent for sludge composting and application thereof. The preparation method comprises the following steps: separately culturing bacillus altitudinis, purple streptomyces variabilis, bacillus stearothermophilus, bacillus subtilis and bacillus licheniformis, then mixing according to a volume ratio of bacterial liquid to obtain mixed bacterial liquid, then inoculating a fermentation medium with the mixed bacterial liquid, and performing enlargement culture to obtain the composite bacterial agent for sludge composting. The composite bacterial agent is mainly applied to high-temperature sludge composting, raises the fermentation temperature fast, maintains high temperature for a long time, can shorten the composting time, reduces the moisture content of a composted material, is low in production cost, environmentally friendly, pollution-free, excellent in performance and high in efficiency, and has relatively good economic benefits and social be
