Treatment method of livestock manure using cheonmaeam {TREATMENT PROCESS FOR LIVESTOCK EXCRETIONS USING PHYLLITE}

The present invention relates to a method for treating livestock manure using cheonmaeuk powder and the manufacture of compost using the same, and in detail, the manure is mixed with a manure treatment agent composed mainly of cheonmaeuk powder to treat manure, and also using the same It relates to the technology to manufacture.

The livestock industry has developed as the consumption of meat has soared due to the progress of the industrial society, and the discharge of manure has increased due to the development of the livestock industry. Livestock manure is a complex of chemicals composed of organic, inorganic, and trace elements, which has the property of fertilizer, which is a nutrient for crops, but is in the form of a mixture of solids and liquids. It is neglected or dumped at sea due to its high economical cost because it is not economical, and even when it is processed, it has become a big problem due to the imperfection of treatment and excessive cost, and it is the main cause of soil pollution and water pollution. It has been recognized. In addition, the disposal of land wastes, such as livestock manure and sewage sludge in 2012, is completely prohibited, so their treatment is recognized as a more urgent problem.

As a method of treating livestock manure, a method of preparing compost by using livestock manure has been proposed, but even in this case, most of the livestock manure is separated into a solid phase and a liquid phase by pretreatment such as dehydration, and the compost is removed using solid content. As a result, the problem of the treatment of the liquid manure generated during the dehydration process is still not solved.

That is, the patent registration No. 10-068074 is a pellet compost manufacturing apparatus and a pellet compost manufacturing method using livestock manure compost, as shown in Figure 2, through the sawdust at the same time mixing the sawdust to livestock manure compost to be treated An aerobic fermentation step of fermenting and ripening the livestock manure compost in which the water content is controlled in a fermentation and post-aging bath to have a water content of 50% to 55%; A first sorting step of separating and sorting the lumped livestock manure compost in which a certain amount of water is removed through the aerobic fermentation step according to the particle size; A grinding step of pulverizing compost having a predetermined particle size or less selected through the first sorting process; A second sorting step of separating and sorting the livestock manure compost finely crushed through the grinding process according to the particle size; A drying step of drying the livestock manure compost below a predetermined particle size selected through the secondary screening process in a dryer under a condition of maintaining a temperature of 110 ° C. to 140 ° C. such that a water content becomes 35% to 45%; A mixing step of mixing and stirring the livestock manure compost 100% by weight, the additives 3 to 5% by weight, and the binder 10 to 20% by weight, respectively, through the drying process; Pellet forming step of molding the mixture in the form of a solid in which the additives and the binder are quantitatively mixed through the mixing step into pellets having a uniform particle size through a pellet molding machine; A dry cooling step of rapidly cooling and drying to obtain pellet compost which is a final product in order to prevent deterioration of the pellet-type livestock manure compost prepared through the pellet molding process; And a weighing and packaging step of finally weighing and packing the pellet granules in the form of pellets solidified through the drying and cooling processes, so that the livestock manure is controlled using a livestock manure compost. As a method of treatment, it still requires a pretreatment, and this pretreatment is the most difficult and expensive process, so it is difficult to solve it, but it does not provide a solution.

In view of the above circumstances, an apparatus for regenerating livestock waste such as livestock manure using dry air to recover organic fertilizer has been proposed, but the dryer according to the related art has a large amount of moisture, like livestock waste. There is an inadequate problem to treat contained waste. That is, since the waste for animal husbandry contains a large amount of waste water, such as urine, when drying without separating the water contained in the waste, the drying time becomes very long, and when it is dried, there is a problem in that the treatment cost is excessive.

Accordingly, the present inventors have completed the present invention as a result of continuing the research to treat livestock manure efficiently and at low cost without the process of solid-liquid separation of livestock manure.

Therefore, the first object of the present invention is to provide a method for treating livestock manure, which effectively treats livestock manure without the solid-liquid separation process using Aphrodite powder.

A second object of the present invention is to provide a compost produced by the treatment of livestock manure according to the first object of the present invention described above.

According to a preferred aspect of the present invention for achieving the above object of the present invention, 100 parts by weight of manure treatment agent and livestock manure 40 ~ in the manure treatment tank maintained at 40 ~ 45 ℃ 50 parts by weight is mixed and stirred, and the mixture is continuously supplied with livestock manure at a rate of 4 to 6 parts by weight based on 100 parts by weight of the manure treatment agent, or additionally mixed and stirred with livestock manure every 1 to 4 hours at the ratio. Livestock manure treatment method is characterized in that the treatment for 21 to 24 hours. In this case, the continuous supply means continuous supply by continuously flowing at a rate of 4 to 6 parts by weight / hour, and additionally supplying livestock manure every 1 to 4 hours may supply 4 to 6 parts by weight every 1 hour or 2 It means supplying 8 to 12 parts by weight every hour, 12 to 18 parts by weight every three hours, or 16 to 24 parts by weight every four hours.

In this case, to remove the evaporated water it is preferable to blow dry hot air to the upper part of the manure treatment tank to perform forced exhaust. The spawn can be used as long as it is suitable for fermentation of organic matter contained in the manure in the manure treatment tank maintained at 40 ~ 45 ℃, preferably agarie bacteria which is a kind of actinomycetes may be used.

The manure treatment agent may be used alone or in addition to the spawn treatment agent, and the at least one mineral powder selected from the group consisting of zeolite, illite, bentonite and vermiculite may be used. In addition, it can be used by additionally mixing coconut block, deodorant or deodorant bacteria as a moisture control agent. Preferably, the weight rock powder: mineral powder: moisture regulator: spawn, deodorant or deodorant may be used in a ratio of 65 to 85: 9.5 to 25.5: 3 to 7: 2.5.

The manure and manure treatment mixture, which is a by-product produced by 21 to 24 hours of treatment by the above method, is made to have a manure treatment because its water content is lowered to 25% or less, and the treatment time according to the above method is 140 to 240 hours. When the fermentation and drying is repeated, the organic content is high and suitable for use as compost. The manure treatment product may be used as a compost after further ripening process.

In the present invention, by using the properties of cheonmaeam properly, by using a combination of physical and biological methods to directly treat livestock manure without pretreatment of livestock manure, leaving no separate treatment of the manure stock solution, the swelling agent required for manufacturing organic compost Since it is possible to manufacture organic compost without excessive use, it is economical because manure processing costs and compost production costs are reduced.

The manure treatment agent of the present invention is composed of aphrodite rock. Phyllite is a metamorphic rock having intermediate properties between slate rock and crystalline schist rock in view of rock tissue and structure. (片 理) stands out. Sometimes it shows a stripe structure created by the modified recrystallization action, and when viewed from the side of convenience, the stripe resulting from the difference in color can be seen. It is usually black that originates from clay or heterogeneous sedimentary rocks, and it is composed of quartz, feldspar, dolomite, chlorite, calcite, quartz, etc., and contains many of the original sedimentary rocks. On the other hand, there are also greens that have tuffs as primary rocks, and they are made of quartz, feldspar, green stone, sulolite, calcite, and the like. Also in this case, the original rock, ore, is contained as a residual mineral. In general, metamorphic rocks originating from dysentery are tissues changed into slate rock, schizophrenic gneiss and gneiss as the metamorphic temperature increases. The natural stone is known to contain approximately 4.88% Fe ₂ O ₃ , 0.31% CaO, 6.60% MgO, 0.04% P, 1.03% K, 0.47% organic matter, and the like.

Aphrodite is pulverized and manufactured in powder form. Aphrodite has the advantage of being very easy to be powdered due to the characteristics of the ore. Aphrodite, a fine porous mineral, has excellent physical adsorptive power and chemical cation substitution, so it can easily absorb and store moisture and fertilizer, and also evaporate easily, supplying plants when necessary and activating soil to increase soil power. It also plays a role in improving.

The manure treatment agent of the present invention, which comprises cheonmaeam as a main component, is porous and has excellent water retention, greatly reducing the water content of manure during manure treatment, and can be used as a substitute for sawdust having a high cost in the production of compost. In addition, compost production removes gas, regulates acidity, and acts as a fermentation promoter, enabling the production of prematurely compost.

The characteristic of the manure treatment method of the present invention is to treat the manure while additionally mixing the manure every fixed time with the manure treatment agent instead of treating the livestock manure at once in a predetermined period. The manure treatment method of the present invention is mixed and stirred in the manure treatment tank maintained at 40 ~ 45 ℃ 100 parts by weight of manure treatment powder and spawn and mixed 40 to 50 parts by weight livestock manure, the livestock manure in the mixture to the manure treatment 100 It is continuously supplied at a rate of 4 to 6 parts by weight relative to parts by weight or additionally mixed and stirred livestock manure at every 1 to 4 hours at the above ratio, characterized in that the treatment for 21 to 24 hours. That is, initially, only 40 to 50 parts by weight of livestock manure is treated with respect to 100 parts by weight of manure treatment agent, and livestock manure at a rate of 4 to 6 parts by weight per hour based on 100 parts by weight of manure treatment agent continuously or every 1 to 4 hours. It is further mixed and treated. If the addition of livestock manure is added at a ratio of 4 to 6 parts by weight / hour, the same parts by weight continuously added after the initial mixing, or 4 to 6 parts by weight every hour, or 2 hours have elapsed It is also possible to add 8 to 12 parts by weight every time, 12 to 18 parts by weight every 3 hours or 16 to 24 parts by weight every 4 hours. The livestock manure in the manure treatment tank reduces the water content by the porous manure treatment agent, and the livestock manure is processed by fermentation by the spawn, which adds livestock manure as much as the amount of livestock manure is treated every certain time. I want to increase. By doing so, the efficiency of the manure treatment is increased, and since the manure does not need to be mixed at once, it is possible to reduce the amount of equipment. After mixing livestock manure, it is important to induce uniform mixing of the manure treatment agent and livestock manure through sufficient agitation and increase contact with air.

The manure treatment agent of the present invention includes any seed for fermentation of the manure organic material, and any one can be used as long as it has an activity in the manure treatment tank maintained at a temperature of 40 to 45 ° C. For example, agarie, a type of actinomycetes, may be cultured and used.

In addition, in the present invention, minerals such as zeolite, illite, bentonite, or vermiculite powder can be used together with the natural rock powder. These silicate minerals are composed of fine porous materials, which have excellent physical adsorption power and chemical cation substitution action, and thus have excellent ammonia and hydrogen sulfide. Since it absorbs up to 20 times of harmful gases, it can be used as a raw material for nitrogen fertilizers.

Odor odor is inevitably generated during the treatment of livestock manure, which can be solved by adding deodorant such as activated carbon or deodorant such as acetic acid bacteria to the manure treatment agent for deodorization.

In order to be used for composting, the water content is preferably about 25% by weight, and the organic content should be 25% by weight or more. The manure treatment agent of the present invention has a high water retention capacity and facilitates the absorption and evaporation of water, thereby activating the evaporation of water contained in the manure, and the organic components decomposed by the spawn are adsorbed on the natural rock powder. The amount of manure added every certain time is the same as the treatment rate, and the amount of the manure is not changed.Internally, evaporation of water and decomposition adsorption of organic substances are repeated. The content is increased to make it suitable for use as compost. According to the present invention, since the water content is maintained at 25% by weight or less by a small time treatment of 21 to 24 hours, the manure treatment is made, and the fermentation drying is repeated with the treatment time of the method as 140 to 240 hours. Is suitable for use as compost because a product having an organic matter content of at least 25% by weight is obtained. The treatment time depends on the organic matter content of the livestock manure.
