Preparation method of livestock and poultry manure base material based on dry-wet separation and microbial deodorization and curing

Abstract

The invention discloses a preparation method of a livestock and poultry manure base material based on dry-wet separation and microbial deodorization and curing. The preparation method mainly comprisesthe following steps: firstly, collecting manure; secondly, carrying out disinfection pretreatment on the manure; thirdly, carrying out solid-liquid separation; fourthly, culturing microorganisms; fifthly, carrying out curing operation; sixthly, packaging a base material; seventhly, carrying out wastewater treatment. According to the preparation method disclosed by the invention, by washing a livestock and poultry breeding place and collecting the manure, the hygienic environment of the breeding place can be ensured and the manure can be collected; manure residues are prepared into the base material through the dry-wet separation; the wastewater is treated and reused, so that the effects of environment friendliness and reuse are realized.

Description

Technical field [0001] The invention belongs to the technical field of livestock and poultry manure treatment, and specifically relates to a method for preparing a base material for livestock manure based on dry and wet separation and microbial deodorization and maturation. Background technique [0002] my country produces up to 3 billion tons of livestock manure each year, and the high cellulose content in livestock manure is an important part of renewable resources. The maturation speed of natural composting poultry manure is slow, and it is not easy to rise temperature, which does not meet the harmless treatment standards of my country's composting. Adding fermentative inoculants to the compost can promote the maturation process of the compost and improve the quality of the compost. The principle of action is to use the decomposition of microorganisms to promote the fermentation and decomposing of livestock manure into excellent green organic fertilizer. Poultry manure is a w...

Problems solved by technology

[0003] However, at the beginning of composting of poultry manure, the inoculated degrading bacteria need to adapt to the composting environment, which is called the lag period. The degrading bacteria generally do not start to reproduce immediately, but readjust their composition of small molecules and macromolecules, including enzymes and cells. Structural components, ready for cell division, and degrading bacteria in the lag phase have weak resistance to external physical and chemical factors (such as salinity, heat, ultraviolet rays, X-rays, etc.), the proliferation rate of degrading bacteria is equal to the mortality rate, and the number of bacteria is almost If it does not increase, the enzyme production efficiency will be low, and the maturing speed at the beginning stage of poultry manure composting will be slow, prolonging the composting time of poultry manure, which is not conducive to large-scale, multi-batch continuous treatment of poultry manure
