Description

Method for manufacturing bio compost using livestock manure {Methods for manufacturing bio compost using livestock manure}

The present invention relates to a method for producing biocompost using livestock manure, in detail, to separate the manure and urine of livestock manure, but the manure is converted into a resource as biocompost, and urine (尿) is purified with micro bubbles so that it can be used for drinking water, showering, and cleaning of livestock houses.

In general, livestock excretions are excretions of livestock such as cattle, pigs, and chickens, and as the demand for livestock increases, the amount of livestock manure generated in livestock facilities increases as the breeding scale of livestock increases.

On the other hand, livestock farms are being driven as the main culprit of environmental pollution and odors from livestock manure while serving as an excellent source of protein to the public. However, livestock manure is an inevitable occurrence when raising livestock. As livestock farmers are indispensable for a stable supply of livestock products, efforts to minimize problems rather than excessive regulation due to odor are necessary for both livestock farmers and the government.

Looking at the current status and causes of odors in livestock farms, in the past, it was thought that odors from livestock can occur normally when doing livestock industry.However, as rural areas become increasingly urban and there are more private houses around livestock farms, there is a problem that the odor cannot be overcome. done. Therefore, the government manages livestock manure and odor discharge facilities, which are the cause of odors, in various laws such as the'Act on the Management and Use of Livestock Manure','Rules on the Promotion of Resource and Use of Livestock Manure', and'The Odor Prevention Act'. Regulations have been established and implemented.

Meanwhile, the daily average amount of livestock manure generated by all domestic livestock farms was 185,069㎥ (as of 2018), which has continued to exceed 170,000㎥ since 2011, and in 2018, the 180,000㎥ wall was also broken. As such, the number of livestock farms is gradually decreasing, but as the scale of the livestock industry increases, the production of livestock manure is rather increasing, and about 40% of the production of livestock manure is known to occur in pig farms.

Accordingly, complaints about odor due to livestock manure are also increasing year by year. The number of livestock odor complaints compiled by the Ministry of Environment has continued to increase from 2838 in 2014 to 4323 in 2015, 6398 in 2016, 6112 in 2017, and 6718 in 2018.

In addition, while the amount of livestock manure is on the rise, marine dumping of livestock manure is expected to decrease due to the prohibition of marine dumping from 2012. Accordingly, an alternative to the treatment method of livestock manure is required, and marine dumping is prohibited. Interest and research on the anaerobic digestion treatment of livestock manure, which can solve the problem and obtain the effect of one stone and two groups of biogas production, are steadily progressing, but in the case of livestock manure, lignin among organic matter is difficult to be decomposed by microorganisms. Due to the slow hydrolysis rate of manure, the digestive system becomes bulky.

In addition, although livestock manure is the main cause of odor, it differs depending on the type of livestock and the manure treatment facility such as ventilation system. In other words, the degree of odor generation varies depending on the type of housing, breeding facility, ventilation system, etc. For example, in the case of pig farms with the greatest number of odor complaints, open pig houses, farms with dense breeding, farms with poor manure treatment and discharge due to insufficient manure treatment system, farms with poor ventilation systems, and narrow compost fields. Farms that are full of sea manure or where manure is spilled out of the compost are mainly identified as sources of odor.

The manure storage tank 2 is configured to obtain bio-compost by mixing bio-energy water or bio-energy water and clay powder.

The mixing ratio of the livestock manure and bio energy water may be 85 to 95:15 to 5 parts by weight.

1 to 5 parts by weight of clay powder may be further mixed with the livestock manure mixed with the bio-energy water.

The microbubble device 8 for purifying the urine separated by the solid-liquid separator 4 can be connected in series in two or three stages to treat the separated urine with a high degree of purification (purification). .

The microbubble device 8 is characterized by being destroyed and destroyed in water due to self-contraction and surface tension while floating very slowly in water because the bubble size is very small (a few microns). When the microbubbles extinguished in this way, when extinguished, a shock wave is generated and a large amount of anions is generated. The shock wave generated upon extinction generates heat, acts on organic/inorganic substances, promotes decomposition, destroys bacteria, and has the ability to sterilize. In addition, negative ions are attached to positive ions, which are pollutants, and as their volume increases, they rapidly rise to the water surface by buoyancy to remove pollutants. They are used for industrial wastewater treatment, and are also used as various sterilization devices. It is widely used as a bathing machine.

In addition, urine flowing into the microbubble device 8 is bubbled by the bubble generator and exploded by microbubbles and/or nano bubbles having very small size and buoyancy. Instantaneous high heat (about 5,500℃) is applied and very slowly and slowly floats, adsorbs to various pollutants in urine and floats, and pollutants (including foreign matter or residue) in the tank float completely. It becomes clear to turbidity. The contaminants are separated from water, purified, sterilized and cleaned by the amount of dissolved oxygen that is greatly increased by microbubbles, and thus urine is also purified, sterilized and cleaned. The urine purified water purified by the microbubble device 8 is supplied as drinking water for livestock such as pigs, or by washing the manure or foreign substances on the body by showering (bathing), and cleaning the floor of the house with water. The odor of (1) is greatly reduced, and the urine purified water used for showering and cleaning the floor flows into the manure storage tank (2) while naturally washing the floor of the livestock and is purified again.

At least one submersible pump is installed at the bottom of the aeration tank 3 to aerate livestock manure that has flowed to a certain level, and oxygen is supplied to the livestock manure by a bubbling device, increasing dissolved oxygen, and proliferating aerobic microorganisms. It deodorizes more than 90% of the odor while doing it. When the aeration time of the aeration tank 3 is sufficiently aerated for 10 to 40 hours depending on the type or condition of livestock manure, most of the odors are deodorized.

The spray nozzle 10 is equipped with a plurality of nozzle heads at predetermined intervals on the ceiling or rafters of the barn 1 like a sprinkler, and sprays them periodically or at any time to perform a shower of livestock and water cleaning of the barn (1) floor. Not only can the odor in livestock and livestock houses be greatly reduced, but also valuable resources can be saved. In addition, hygienic management of livestock and livestock houses by bathing and cleaning is possible. It has the effect of preventing the back and raising it healthy.

The drinking water of the livestock and the water used for showering and cleaning the floor of the barn (1) are recovered and stored in a manure storage tank (2), separated into aeration and urine as described above, and separated into a microbubble device (8). After being purified by water treatment, it is stored in the purified water storage tank 9 and reused for drinking water of livestock 1 and for cleaning the floor of the livestock and shower, so that valuable water resources can be saved.

The solid-liquid separator 4 separates solid component and liquid component urine from livestock manure discharged from the aeration tank 3. That is, the solid-liquid separator 4 is used to separate livestock manure in the form of a slurry in which solid and liquid are mixed into solid and water, and is divided into a centrifugal separator, a swash plate separator, a drum filter separator, etc. according to the separation method. , The centrifugal separator separates solids and moisture using centrifugal force, the swash plate separator separates solids and moisture by passing the slurry through an inclined filtration screen, and the drum filter separator supplies the slurry into the cylindrical drum filter, The solid content separated by water through the filter is separated by collecting it with high-pressure washing water or washing air.

The livestock manure (including manure wastewater, domestic sewage, etc.) contains a large amount of organic substances, and microorganisms that take in nutrients from such organic substances live and proliferate in large quantities, and these microorganisms are undegraded organic substances. Sludge is a mass that is a mixture of solids and moisture by aggregating together.

The first stirring drying furnace 5 and the second stirring drying furnace 6 are equipped with a stirring blade rotating by a motor and a hot air dryer or an electric heating heater to dry the livestock manure while agitating it, and the type or state of the livestock manure. It differs depending on the situation, but it is sufficiently dried for 10 to 40 hours to facilitate fermentation and drying of livestock manure to obtain a semi-dried or completely dried biocompost with a desired moisture content.

In the case of the first stirring and drying furnace (5), the mixture is sufficiently stirred and dried for 10 to 40 hours at a temperature of 60 to 80° C. to obtain semi-dried biocompost in the form of a semi-dried cake with a moisture content of 40 to 60%, and the second stirring and drying furnace Using (6), the mixture is sufficiently stirred and dried for 10 to 40 hours at a temperature of 60 to 80°C to obtain a biocompost with 8 to 15% moisture content or close to complete drying.

In the present invention, if necessary, the aerated livestock manure is stirred and dried using one stirring drying furnace with excellent stirring and drying efficiency, or the first stirring drying furnace 5 and the second stirring drying furnace 6 are stirred in one It can also be combined or integrated into a drying furnace.

The pellet processing unit 7 has excellent advantages in terms of storage, transportation, fertilization, etc. by extruding biocompost completely dried or close to dryness with a moisture content of 8 to 15% to pelletize. Since the pellet device is an apparatus and method used in other industrial fields, a detailed description thereof will be omitted in the present invention.

In the present invention, for convenience of explanation, pig house was described as an example, and when bio energy water is provided as drinking water while raising pigs, since bio energy water is included in livestock manure. A small amount of Bio Energy Water may be mixed in the aeration tank 3 or the mixing may be omitted.

The'Bio Energy Water', in order to facilitate the absorption of water that is beneficial to humans as well as animals and plants, primarily filters groundwater to pass elvan, and absorbs far-infrared rays emitted by heating of ceramic balls into the water. A water molecule (H2O) cluster is finely separated through magnetization treatment. A filtering device that removes impurities contained in water flowing from the tap water or groundwater, and the water filtered by the filtering device is supplied to A first activation treatment device for finely separating the clusters of water molecules, and a second activation treatment device for subtly separating the clusters of water molecules by radiating far-infrared rays into the water passing through the first activation treatment device, It may be configured to include a third activation treatment device for finely separating the clusters of water molecules by applying a magnetic field to the water passing through the second activation treatment device.

In the present invention, since bioenergy water is included in livestock manure, the odor of livestock manure (pig manure) is greatly deodorized.

In the present invention, when bio-energy water is included in livestock drinking water, the odor of livestock manure (pig manure) is greatly deodorized because bio-energy water is also included in livestock manure (pig manure).

By mixing the above drinking water with bio-energy water in an amount of 80 to 90: 10 to 20 parts by weight and supplying it to the pigs, more than 95% of the odor generated from the feces and urine excreted by the pigs is removed, greatly improving the pig house environment. And because the pollution of the surrounding environment, such as the surrounding air, is greatly improved, it is possible to escape from the odor of the pig house.

The bio-energy water increases dissolved oxygen in drinking water and has a high evaporation rate of ammonia in discharged urine.

In the present invention, more than 95% of the odor is removed by spraying the white clay powder on the bottom of the barn 1, and biocompost is made by the clay powder and/or bio energy water mixed with the pig manure.

In the present invention, when 1% clay powder is mixed with livestock manure, most of ammonia is removed and deodorized.

On the other hand, most minerals, animals, and plants have polarity, but white soil is non-polar, so it can be applied to most minerals, animals, and plants, and also has strong quantum energy at high and low temperatures ( Quantum Energy), far-infrared rays, and natural anions are radiated to improve immunity and vitality to animals and plants.

Since the clay is composed of minerals such as silica (SiO ₂ ), alumina, iron, calcium, magnesium, potassium, sodium, and titanium, and various enzymes, far-infrared rays and anions necessary for the growth and growth of animals and plants are radiated in large quantities. It is'the mineral of life in which ki is alive'.

In addition, clay is a honeycomb structure with a large surface area, and a large amount of far-infrared rays and anions are stored, and when heated, these far-infrared rays and anions are emitted to the outside, stimulating the molecular activities of surrounding objects to purify the natural environment. It is an important resource to promote human health.

In addition, the influence on the human body includes the increase of immunity and self-healing ability, improvement of blood flow, and the increase of α wave.The effects include maintenance of a healthy body, prevention of disease, recovery, improvement of comfort and concentration, etc. Can be lifted.

The biocompost of the present invention contains a large amount of nitrogen and potassium phosphate, making it an excellent compost.

In the present invention, since bio-energy water and/or clay powder are mixed, the odor of livestock manure is removed by more than 95%, so the surrounding environment including the livestock house (1) is greatly improved, and liquid urine separated by solid and liquid after aeration It can be used as bio-liquid fermentation (or bio-livestock manure fermentation liquid ratio), and can be prepared as bio-dried compost obtained by first and second stirring-dried powder, or bio-compressed compost obtained by pelletizing bio-dried compost.

The bio-liquid manure, bio-dried compost, and bio-compressed compost are made of biocompost with excellent nutrition, which greatly helps increase crop production or improve yield, and bio-compressed compost is easy to store, transport and store by pelletizing, It has the advantage of being able to fertilize as needed regardless of the season. In addition, it is possible to prevent unauthorized discharge or dumping of livestock manure into rivers or seas.

The biocompost of the present invention contains a large amount of three major fertilizer components such as nitrogen (N), phosphoric acid, and potassium, organic matter, and other various substances necessary for the growth of crops, and also plays the role of a soil conditioner to improve soil environment when used as a resource. And it is possible to promote eco-friendly agriculture with natural circulation.
