Automatic pig breeding farm waste treatment system and method

Abstract

The present invention discloses an automatic pig breeding farm waste treatment system and method. The system comprises inside-pigsty feces and urine separation mechanical manure scraping equipment, outside-pigsty manure automatic transporting equipment, manure fermentation equipment and sewage purification treatment equipment. According to the large-scale pig farm automatic waste treatment technology provided by the present invention, automatic control can be realized, and working efficiency of feeders is raised; with utilization of a mechanical manure scraper, water using amount of a large-scale pig farm is saved, and sewage treatment burdens are also reduced; and an electric transportation dung-cart is used for transporting the manure to a fermentation tank, and organic fertilizers obtained after the fermentation are applied to fields, thereby reducing the using amount of chemical fertilizers.

Description

technical field [0001] The invention belongs to the field of animal husbandry and breeding equipment, and relates to an automatic manure treatment system and method for pig farms. Background technique [0002] my country is a big pig raising country, and the intensification and automation of pig raising production has become an inevitable trend of my country's pig raising industry. At this stage, there are still some problems in large-scale pig raising in my country, such as unbalanced production development, large price fluctuations, low production efficiency, difficult manure treatment, and lack of front-line pig raising personnel. The most important and most difficult problem to solve is large-scale The manure of pig farms is difficult to deal with, which seriously pollutes the environment. [0003] At present, the main pig house manure cleaning processes in my country mainly include dry manure cleaning, water soaked manure, fermentation bed and mechanical manure scraping...

Problems solved by technology

At this stage, there are still some problems in large-scale pig raising in my country, such as unbalanced production development, large price fluctuations, low production efficiency, difficult manure treatment, and lack of front-line pig raising personnel. The most important and most difficult problem to solve is large-scale It is difficult to dispose of manure in pig farms, which seriously pollutes the environment

[0003] At present, the main pig house manure cleaning processes in my country mainly include dry manure cleaning, water soaked manure, fermentation bed and mechanical manure scraping board, etc. These manure cleaning processes have their own disadvantages: dry manure wastes labor; water soaked manure is easy to form anaerobic fermentation, resulting in A large amount of harmful gas and a large waste of water resources will cause troubles for subsequent sewage treatment; turning over the bedding in the fermentation bed is laborious and laborious, and mosquitoes are easy to produce in summer, and the temperature of the fermentation bed is high in summer, and pigs are unwilling to move on it; mechanical scraping of manure The board is currently an ideal pig house manure cleaning process, but it has the disadvantage of not cleaning the manure

[0004] At present, my country's pig manure resource utilization mainly includes biogas projects and aerobic composting to produce fertilizers. The disadvantages are that biogas fermentation is affected by seasonal temperatures, and biogas slurry treatment is difficult; Nitrogen loss

[0005] Therefore, it is necessary to find a new manure treatment process to solve the problem of difficult manure treatment in large-scale pig farms
