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.
