The invention discloses a technological method for degrading feces from livestock and poultry by using complex microbial communities, and relates to the technical field of environment-friendly biological treatment. The technological method comprises the steps that 1, the complex communities are put on stacked materials formed through the combination of sawdust, straw, rice husk and other agricultural wastes for even mixing, wherein the moisture is controlled to 30-35%, and the standing time is 12-24 hours; 2, the well-stirred feces from livestock and poultry are sprayed on the stacked materials in the first step, the mixture is fully and uniformly stirred, the water content is adjusted to 55-65%, and stacking fermentation is conducted for 24-48 hours, wherein the complex microbial communities include fecal alkali-producing bacteria, nitrification and denitrification bacteria, autotrophy sulfuration and deodorization bacteria, low-temperature heterotrophic bacteria, actinomycetes, thermophilic bacteria, cellulose decomposition bacteria and bacillus subtilis. By means of the technological method, the hazards of foul gas, sewage and excrement in the feces from livestock and poultry to the environment are solved fundamentally, zero release and zero pollution are achieved, no bad smell, no waste residue and no waste water are discharged, meanwhile, the residual stacked materials can be prepared into organic fertilizers, and waste materials are turned into wealth and recycled.
