Waste comprehensive utilization process of large-scale beef cattle farms

Abstract

The invention belongs to the technical field of waste comprehensive utilization of beef cattle farms, and discloses a waste comprehensive utilization process of the large-scale beef cattle farms. The process is characterized by comprising the following steps that (1), cattle feed crop raw materials from farmland are used for preparing organic feed for cattle, and the organic feed is used for cattle farming; (2), cattle dung, urine and flushing water are generated during cattle farming and are collected; 10-90% of cattle dung is used for planting agaricus bisporus, and mushroom dregs generated in the planting process of the agaricus bisporus are used for producing organic fertilizers; the rest of cattle dung, the urine and the flushing water are used for producing biogas and biogas slurry at a biogas station, biogas residues are used for producing organic fertilizers, the biogas slurry is used for farmland irrigation, and the organic fertilizers are used for farmland fertilization. The process not only solves the environmental pollution problem, but also improves the rural energy structure, the mushroom dregs generated in the planting process of the agaricus bisporus and the biogas residues generated by a biogas digester are used for manufacturing the organic fertilizers, the yield of crops is improved obviously, the use number of the fertilizers is reduced, and auxiliary non-point source pollution is relieved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of waste in beef cattle farms, and in particular relates to a process for comprehensive utilization of waste in large-scale beef cattle farms. Background technique [0002] Agaricus bisporus belongs to the subphylum Basidiomycotina, and the flesh is fat and tender, delicious, nutritious, and has certain medicinal value. my country's artificial cultivation began in 1935. At present, the Agaricus bisporus cultivated in my country is a white variety, which is mainly suitable for selling fresh products or processing them into cans. [0003] In recent years, my country's livestock and poultry breeding industry has rapidly developed from courtyard breeding to intensive, large-scale, and commercialization. Especially around cities, there are more and more livestock and poultry farms with larger scales. Intensive, large-scale livestock The economic benefits of poultry farming are obvious...

Problems solved by technology

[0012] The object of the present invention is to provide a process for comprehensive utilization of waste from large-scale beef cattle farms. This process not only solves the problem of environmental pollution, but also improves the rural energy structure. Biogas residues can be used to make organic fertilizers, which can not only significantly increase the yield of crops, but also reduce the use of chemical fertilizers and reduce pollution from non-point sources
