Recycling pig raising system for large-sized pig farm

Abstract

The invention discloses a recycling pig raising system for a large-sized pig farm and relates to the technical field of pig raising. Cultivating land is arranged at the periphery of the pig farm; a pig manure collecting and recycling system is arranged in the pig farm and comprises a methane fermentation pool; a methane collecting and utilizing system and a fermented residue collecting pool are arranged in the methane fermentation pool; the methane collecting and utilizing system is electrically connected with a house power supply system; a plurality of pipelines are arranged on the fermented residue collecting pool and are communicated with the cultivating land at the periphery. The recycling pig raising system disclosed by the invention has the beneficial effects that pig manure is collected and repeatedly recycled by the pig manure collecting and recycling system, so that electric bills are saved for pig farmers, and the feeding environment of the pig farm is improved.

Description

technical field [0001] The invention relates to the technical field of pig raising, in particular to a recycling pig raising system in a large pig farm. Background technique [0002] With the rapid development of China's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. Usually, pig farms first discharge the pig manure into the cesspit around the pig farm. , and then after a certain period of time, a special person will take it away and sell it, but this will cause the surrounding air to be stinky during the backlog period, which not only affects the lives of people around, but also is very unfavorable to the pigs themselves. It is extremely easy to cause the occurrence of infectious diseases; if a large amount of pig manure and urine wastewater is not handled properly, the first is to affect the water quality, because the pig manure and urine contain a large amount of organic matter and org...

Problems solved by technology

[0002] With the rapid development of China's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. Usually, pig farms first discharge the pig manure into the cesspit around the pig farm. , and then after a certain period of time, a special person will take it away and sell it, but this will cause the surrounding air to be stinky during the backlog period, which not only affects the lives of people around, but also is very unfavorable to the pigs themselves. It is extremely easy to cause the occurrence of infectious diseases; if a large amount of pig manure and urine wastewater is not handled properly, the first is to affect the water quality, because the pig manure and urine contain a large amount of organic matter and organisms, which consume dissolved oxygen in the water when decomposed, and then destroy the ecological balance, such as tap water When the water source is polluted by pig feces and urine wastewater, the water will have a foul smell, which will affect people's drinking; second, it will hinder environmental sanitation, because pig feces and urine will emit a pungent smell, and it is easy to breed mosquitoes and flies, seriously affecting the environment. The quality of the living environment in neighboring communities is harmful to health. Third, it is easy to cause disease transmission. Since pig manure and urine often contain a large number of pathogenic bacteria, if they are not treated and directly used for crop irrigation or directly discharged into rivers, there will be extreme dangers. major disease transmission hazard

On the other hand, in the process of raising live pigs, in order to increase lean meat and prevent and control diseases, antibiotics, bacteriocins, hormones and other drugs are mostly used. Although the pork production has been increased, the pork eaten by consumers may still be There are a large amount of undecomposed antibiotics remaining, and the "table pollution" caused by drug residues in pork will cause great harm to the human body and directly affect people's health
