Decomposition treatment method of livestock and poultry breeding waste and application of decomposition treatment method

Abstract

The invention relates to the technical field of livestock and poultry breeding waste treatment, in particular to a decomposition treatment method of livestock and poultry breeding waste and an application of the decomposition treatment method. The decomposition treatment method comprises the steps of (1) performing solid-liquid separation on the livestock and poultry breeding waste through a biomass carbon filter layer to obtain separation liquor and separation residues, disinfecting the separation residues, and performing drying and crushing; (2) mixing fermentation liquor obtained through fermenting morchella esculenta with a PDA culture medium containing nitrogen and sulfur doped fluorescence carbon dots, with clostridium butyricum and streptomycete to prepare a microorganism fermentation agent, adding the microorganism fermentation agent and auxiliary materials to the separation residues to obtain fermentation raw materials, and performing malposition fermentation treatment on thefermentation raw materials in an external electric field to obtain fertilizer; and (3) enabling the separation liquor to be made into plant nutrition liquor. According to the method, the malposition fermentation treatment is performed on the livestock and poultry breeding waste in the external electric field with the microorganism fermentation agent based on morchella esculenta fermentation liquorto prepare the fertilizer, high-efficiency fermentation is realized, besides, the content of heavy metal ions in the livestock and poultry waste can be significantly reduced, and good diminishing effects on antibiotics, antibiotic medicine resistant bacteria and antibiotic resistant genes in the livestock and poultry breeding waste can be achieved.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding waste treatment, in particular to a livestock and poultry breeding waste digestion and treatment method and its application. Background technique [0002] With the rapid development of large-scale livestock and poultry breeding industry in my country, the problem of environmental pollution caused by livestock and poultry manure is becoming more and more serious. According to the data of the "First National Pollution Source Census Bulletin", among the three major pollutant emissions from agricultural non-point sources, domestic sources and industrial sources, agricultural non-point source COD and total nitrogen emissions account for 43.7% and 57.2% of national emissions, respectively. %, and the main pollution of agricultural non-point sources comes from livestock and poultry breeding industry. At present, livestock and poultry breeding in my country produces 3.8 billion tons ...

[0003] Poor resource utilization channels for livestock and poultry farming waste not only creates environmental pressure, but also affects the development of animal husbandry production

Relevant departments found that due to the lack of taxation in the breeding industry, the rich people are not rich in counties, and the difficulty in handling livestock and poultry manure, some places have insufficient understanding of the development of animal husbandry production and the resource utilization of livestock and poultry manure. ", unreasonable setting of breeding limits, simple closure of farms, discouragement and support for resource utilization of livestock and poultry manure, many biogas projects are idle, not only is not conducive to solving the problem of livestock and poultry breeding manure, but also has a negative impact on local livestock and poultry manure. The stable supply of products has caused a certain impact
