Large-scale recycling comprehensive treatment technology for livestock and poultry breeding liquid dung

Abstract

The invention discloses a large-scale recycling comprehensive treatment technology for livestock and poultry breeding liquid dung. The large-scale recycling comprehensive treatment technology is characterized by being a technical route consisting of a livestock and poultry farm, a dung collecting pipeline, a solid-liquid separator, a multistage sedimentation tank, an ABR anaerobic tank, a biogas slurry regulating tank, an acid hydrolysis pool, a first-stage facultative tank, a first-stage aerobic tank, a sedimentation tank 1, a second-stage facultative tank, a second-stage aerobic tank, a sedimentation tank 2, an MBR reaction tank, a disinfecting tank, an oxidation pond, an up-to-standard clear water reservoir and clear water returning to the livestock and poultry farm for recycling; the problem of pollution caused by large-scale livestock and poultry breeding liquid dung is thoroughly solved; the environment is purified and wastes are changed into valuables; economical benefits and social benefits of enterprises are realized, and coordinated and sustainable development of ecological agriculture and ecological aquaculture is greatly promoted; the large-scale recycling comprehensivetreatment technology accords with the treatment principles of reclamation, harmlessness and recycling of the liquid dung.

Description

technical field [0001] The invention relates to a comprehensive treatment process for resource utilization of large-scale livestock and poultry breeding dung and water, which belongs to the field of livestock and poultry breeding and environmental protection. Background technique [0002] With the development of my country's livestock and poultry breeding industry towards standardization and ultra-large scale, livestock and poultry breeding has formed a very large industry. While the livestock and poultry industry has developed rapidly, it has also brought great pressure to environmental protection, mainly because the excrement and water produced by livestock and poultry breeding are not properly treated. Insufficient awareness of the importance and weak awareness of environmental protection; the most important thing is that the process route for the treatment of livestock and poultry manure is not reasonable enough, comprehensive enough, and not systematic enough, and the c...

While the livestock and poultry industry has developed rapidly, it has also brought great pressure to environmental protection, mainly because the excrement and water produced by livestock and poultry breeding are not properly treated. Insufficient awareness of the importance and weak awareness of environmental protection; the most important thing is that the process route for the treatment of livestock and poultry manure is not reasonable enough, comprehensive enough, and not systematic enough, and the cost of treating manure from livestock and poultry farming is too high.
