Problems solved by technology

The disadvantages of this method are: (1) the crushing process of sick and dead pigs increases the processing cost, which is prone to cross-infection and increases the risk of epidemic transmission; Waste water and waste gas have high treatment costs and are prone to secondary pollution: (3) Sick and dead pigs are rich in organic matter such as protein and fat, as well as large, neutral and trace elements and inorganic salts. Landfill treatment wastes resources, and the utilization rate of resources Low
[0007] Commodity feed is one of the main costs of livestock and poultry farming, and the cost of feeding only commercial feed is high. In some stages of breeding, only feeding with commercial feed will cause problems such as overweight of livestock and poultry, affecting growth and decreasing meat quality

Embodiment 1

[0121] A pollution ecological control method for pig farms based on the combination of breeding and breeding, including:

[0122] 1. Separation of the source of the barn and water saving: the source separation and water-saving barn 101 separates rain and drinking water, and the rain and drinking water are discharged to the ditch outside the barn instead of being mixed with feces and urine. Water-saving flushing is adopted And mechanical scraping or artificial dry cleaning of manure, so that rainwater and drinking water will not be mixed into pig manure and urine at the source of the barn, so as to minimize the amount of manure and urine. Cleaning barns uses high-pressure water guns or even high-pressure air. Mechanical The pig manure cleaned up by scraping manure or artificial dry manure is stacked in the dry manure shed 301, and then the manure shed 301 transports the manure to the solid high-temperature aerobic fermentation system 104 and the animal-derived feed factory 103 r...

Embodiment 2

[0156] A pollution ecological control method for pig farms based on the combination of breeding and breeding, including:

[0157] 1. Separation of the source of the barn and water saving: the source separation and water-saving barn 101 separates rain and drinking water, and the rain and drinking water are discharged to the ditch outside the barn instead of being mixed with feces and urine. Water-saving flushing is adopted And mechanical scraping or artificial dry cleaning of manure, so that rainwater and drinking water will not be mixed into pig manure and urine at the source of the barn, so as to minimize the amount of manure and urine. Cleaning barns uses high-pressure water guns or even high-pressure air. Mechanical The pig manure cleaned up by scraping manure or artificial dry manure is stacked in the dry manure shed 301, and then the manure shed 301 transports the manure to the solid high-temperature aerobic fermentation system 104 and the animal-derived feed factory 103 r...

Embodiment 3

[0190] An ecological control method for chicken farm pollution based on the combination of breeding and breeding, including:

[0191] 1. Separation of the source of the barn and water saving: the source separation water-saving barn 101 separates the rain and drinking water, and the rain and drinking water are discharged to the ditch outside the barn instead of being mixed into the feces, so that the feces can be reduced to the greatest extent. Quantification, the chicken manure cleaned by mechanical scraping or manual dry cleaning is stacked in the dry manure shed 301, and then the dry manure shed 301 transports the manure to the solid high-temperature aerobic fermentation system 104 and the animal-derived feed factory 103 respectively;

[0192] 2. Black soldier fly breeding: first adjust the moisture content of pig feces to an appropriate range, then inoculate an appropriate amount of black soldier fly larvae on the feces, and after a period of growth and reproduction, a mixtu...

Abstract

The invention relates to an ecological treatment system for pollution of a livestock and poultry farm based on combination of planting and breeding. The ecological treatment system comprises a source-separated water-saving fence house, a pollution control factory, a feed factory and a supporting planting land, wherein the pollution control factory and the feed factory are operated by professionalteams to carry out professional disposal on livestock and poultry manure; the pollution control factory consists of a solid high-temperature aerobic fermentation system, a liquid medium-temperature anaerobic fermentation system, a cracking and propagation system, a heating and heat balance system, a waste gas treatment system and a detection control system; and sensors of the detection control system are arranged in the above systems to set, detect and control each key parameter. The ecological treatment system provided by the invention comprehensively treats wastes such as excrement and urineand waste gases generated in a breeding process of a large-scale pig farm, realizes resource utilization, and has important significance for rural environmental protection, benign development of animal husbandry and implementation of an energy sustainable development strategy.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a livestock and poultry farm pollution ecological control system and method based on the combination of breeding and breeding. Background technique [0002] In recent years, the aquaculture industry has developed rapidly towards intensification and scale. While providing the market with rich and high-quality livestock and poultry products, it also brings a large amount of pollutants such as feces, urine, and dead livestock and poultry. If they are not disposed of in a timely and effective manner, It will cause serious pollution to the rural environment. In recent years, while vigorously supporting and promoting large-scale and intensive livestock and poultry farming, the state has also issued a series of standards and policies, such as "Technical Specifications for Biogas Fertilizer Application" (NT / T2065-2011). [0003] Aerobic fermentation (compost...
