Abstract

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.

Description

technical field [0001] The invention relates to the technical field of environmental protection biological treatment, in particular to a process method for degrading livestock and poultry manure by using microbial composite flora. Background technique [0002] With the rapid development of my country's livestock and poultry breeding industry, the pollution of farms and their surroundings has become increasingly prominent. A large amount of nitrogen, phosphorus, mineral elements and the odorous gases such as ammonia and hydrogen sulfide in untreated livestock and poultry manure, It not only brings olfactory discomfort to the residents around the farm, but also seriously deteriorates the quality of air, water and soil, and destroys the ecological balance; effectively dealing with the pollution of the surrounding environment by livestock and poultry manure is the key to building a new socialist countryside. important prerequisite. At present, the treatment methods of livestock a...
