Deodorizing System for livestock facility

The present invention relates to a odor treatment system for livestock facilities, and more particularly, to a microbial active liquid decomposed and activated by aerobic microorganisms in a liquefaction facility that produces livestock manure from a livestock barn (pig). The present invention relates to a livestock facility odor treatment system that can increase the odor removal efficiency as well as achieve an environment-friendly livestock environment by circulating and recycling the circulating water of the odor prevention facility to remove the wastewater.

Odor generated in the barn consists mainly of odorous substances produced by anaerobic decomposition of manure, and livestock manure contains organic substances and nutrients that are used as energy sources of naturally occurring microorganisms.

When these livestock manure is decomposed by microorganisms, it generates various gases and volatile substances. When anaerobic decomposition of livestock manure occurs anaerobicly, these gases and constituents odor, whereas aerobic decomposition of livestock manure produces mainly carbon dioxide, water and small amounts of ammonia, and carbohydrates are metabolized by alcohol. Decomposes into aldehydes, ketones and organic acids.

In addition, the organic material in livestock manure is mainly composed of proteins, carbohydrates and fats, and anaerobic decomposition of proteins produces ammonia and volatile organic acids. And amino acids containing sulfur components are broken down into sulfides and mercaptans, which are harmful to the human body.

It is known that there are about 200 kinds of odor generating substances in the barn, among which the most odorous components are volatile fatty acids (VFA, Volatile Fatty Acids), hydrogen sulfide, p-cresol, insole, Sketole, Diacetyl and Ammonia.

Hydrogen sulfide is typically a colorless flammable gas and smells like rotten eggs even at low concentrations. Since it has a higher specific gravity than air, it remains on the ground and accumulates in poorly ventilated houses. Chronic inhalation of these hydrogen sulfides can cause fatal diseases in the eyes, respiratory tract and nervous system, as well as in humans and animals.

In addition, ammonia is a colorless gas at room temperature and normal pressure, which causes irritating and unpleasant odors such as snoring at concentrations of 0.7 ppm and above, and can cause diseases of the nose and respiratory system at a concentration of 4 ppm.

These odors are generated from livestock manure facilities such as barn floors, feeders, and livestock bodies, and manure temporarily stored inside the barn, and odor-causing substances are combined with dust particles floating in the air or sinking to the bottom of the barn. Spread out.

In addition, since most of the odor gas and dust generated in the barn act as a hazard to both pigs and managers, it is necessary to properly treat manure and dust to remove odors.

Therefore, in recent years, among the various odor removal methods, carbon dioxide, water, and mineral salts are activated using a liquefaction facility that activates aerobic microorganisms of livestock manure and induces liquid liquefaction, and microorganisms attached to the carrier with gas and dust having the odor collected from the barn. Research and investment using microorganisms, such as microbial deodorization method to convert to the has been actively made.

However, in the conventional biofilter using the microorganism deodorization method, as shown in FIG. 6, the odor is sucked into the biofilter in which the carrier is contained, and a predetermined water made of water, a pH adjuster, and a nutrient agent. The odor is purified through the microorganisms in the carrier sprayed and is configured to discharge it into the atmosphere through the purification outlet.

Here, PH regulator and nutrient used to cultivate aerobic microorganisms have to be purchased separately and mixed with water to be provided in the carrier steadily, there was a problem in that the drug costs and labor accordingly.

In addition, in order to remove the odor of the barn, not only the treatment of livestock manure and dust, but also the inside facilities of the livestock, the bottom of the house, the wall, etc. are cleaned, and the manure pit is washed with recycled water at regular intervals or There was a problem in that the recycled water flows through the manure pit to maintain cleanliness, resulting in a lot of maintenance costs.

Therefore, there is an urgent need for a odor treatment system capable of effectively removing odors from livestock houses while greatly reducing labor costs, chemical costs, maintenance costs, and the like.

Accordingly, the present invention has been made to solve the fundamental problems of the prior art,

An object of the present invention is to produce livestock manure produced in a barn (pighouse) as a high-quality organic liquid fertilizer from which odorous substances have been removed, and the microbial active liquid decomposed and activated by aerobic microorganisms in the course of producing the liquid fertilizer is the stench of a pig (pig). Livestock facility odors to effectively control the odor of the whole house by circulating and recycling it with the circulating water of the odor prevention facility to remove the To provide a treatment system.

The present invention for achieving the above object is a collection tank for collecting livestock manure discharged from the barn, odor collection duct for collecting the odor exhausted from the barn, and odor collected in the odor collection duct by using aerobic microorganisms In a livestock facility equipped with a biofilter; A liquid liquefaction facility comprising a solid-liquid separator for solid-liquid separation of livestock manure collected in the sump into manure and solids; and a liquid liquefaction tank for producing the separated manure as a liquid by using aerobic microorganisms; A pretreatment facility section for filtering the liquid mixture of the liquefaction tank to be separated into a concentrated liquid and a microbial active liquid; A microbial active liquid supply pipe installed to supply or spray the microbial active liquid filtered through the pretreatment unit; Characterized in that consisting of a distribution tube installed to supply the microbial active liquid supplied to the microbial active liquid supply pipe to the upper portion of the biofilter.

Here, the pretreatment facility is to filter the manure and sludge (microbial mass) contained in the liquid mixture of the liquefaction tank and to utilize the microbial active liquid containing only useful microorganisms as the circulating water and cleaning water, the configuration is a plurality of membranes are built-in The housing is provided, the mixed solution inlet and the concentrate outlet is provided in the housing, characterized in that the microbial active liquid outlet through which the microbial active liquid filtered through the separator is connected to the microbial active liquid supply pipe.

In addition, between the pretreatment facility and the microbial active liquid supply pipe is characterized in that the microbial culture medium further comprises a microbial culture to further increase the useful microorganisms of the microbial active solution by putting a microbial culture medium.

Production of livestock manure from pig barns with high-quality organic liquid fertilizer from which odorous substances have been removed to remove odor generated from manure, prevent the discharge of wastewater due to manure, and also produce aerobic microorganisms in the process of producing the liquid fertilizer. By using the microbial active liquid decomposed and activated by the circulating water in the odor prevention facility to remove odors from the livestock house (pig), there is no need to purchase additional drugs such as PH regulators and nutrients used to cultivate aerobic microorganisms. And maintenance costs are reduced.

In addition, the microbial activator is recycled and recycled into the scavenger's clean water to wash the house's internal facilities and manure pit such as the bottom and wall of the shed at regular intervals or to ensure that a constant amount of microbial activator flows through the manure pit. It can reduce the occurrence of odorous substances in (Dongsa) and prevent the occurrence of various diseases, which significantly protects livestock or managers, saves the cost of water and electricity used in pigs, and improves the internal environment of livestock facilities. And it is effective to improve the state of health.
