Description

Nature-friendly non-powered high-speed fermentation method for organic matters

The present invention relates to a nature-friendly high-speed fermentation method for organic matter without power, and more particularly, to a method for high-speed fermentation of organic matter without power, which can facilitate aerobic fermentation even in the absence of power.

In today's world, rapid industrialization and population growth are causing mass production and mass consumption, which in turn generates a large amount of organic waste that exceeds the self-cleaning capacity of natural ecosystems. These organic wastes are sewage sludge and food waste. Livestock manure, slaughtering by-products, agricultural and fishery and forestry waste, etc., are mostly loaded with organic matter, which has a huge adverse effect on the environment.

Due to this seriousness, countries around the world are making efforts to build a resource circulation type system that focuses on recycling, breaking away from the existing treatment methods such as ocean dumping, land reclamation, and incineration. Among these efforts to protect the natural environment, various types of technology development and research are being attempted to recycle organic waste into processed food, livestock feed, and crop compost.

In order to recycle organic waste, a digestion process that ferments and decomposes organic matter into stable substances by microorganisms is inevitable. Currently, technology development for anaerobic digestion process has been largely carried out at the policy level, showing tangible results in securing new and renewable energy, which is an alternative energy, centering on large-scale business sites that process sewage sludge and food waste.

Technological development for the aerobic digestion process has also made a lot of progress, but there is a limit to its application from the perspective of small agricultural and livestock industry workers because a considerable amount of equipment and capital are required. Due to this, in many small-scale agricultural and livestock industries where organic waste is generated the most, untreated organic waste continues to cause environmental pollution such as odor.

The 'vertically sealed high-speed fermenter' of Korean Patent Registration No. 10-1190186 (October 5, 2012) relates to a vertically sealed high-speed fermenter that ferments livestock manure to produce organic fertilizer. Since it has a drive device, an impeller, an air supply device, a machine room, etc., there is a disadvantage that expensive equipment and excessive maintenance costs such as power use are required.

The 'closed circulation type high-speed organic matter fermentation apparatus' of Korean Patent Registration Publication No. 10-1801910 (2017.11.21) stirs and ferments fermented materials such as food waste and livestock manure, purifies polluted air, and supplies purified air at a certain temperature It is related to the high-speed fermentation of organic materials, such as agitating device, blower, dust removal device, odor removal device, etc. inside. This also has the disadvantage of requiring excessive maintenance costs such as expensive equipment and power use.

Korean Patent Registration No. 10-1794611 (2017.11.01), 'Upright stirring high-speed fermenter with externally managed fermentation air supply system' is an air supply device, stirring device, and compressed air tank for fermentation of organic matter. Since it is in the form of having a lamp, this also has the disadvantage of requiring excessive maintenance costs such as expensive equipment and power use.

As described above, most of the prior art for recycling organic waste through an aerobic digestion process have disadvantages in that expensive equipment and excessive maintenance costs are required, which are difficult to introduce in small businesses regardless of performance and effectiveness.

In addition, with the conventional method, organic wastes are stored for a long time in a natural environment after providing suitable conditions such as carbon-to-nitrogen ratio (C/N ratio), pH (hydrogen ion concentration), and moisture content necessary for the fermentation of microorganisms. Or, for rapid aerobic fermentation, repeated flipping for air inflow, or inducing natural ventilation by burying a porous tube in the compost heap, etc. It has the disadvantage of unavoidable environmental pollution such as odor generation.

Therefore, for the aerobic digestion process of organic waste, even without any mechanical system that requires power such as agitator, blower, warm air, motor, etc., the air required for aerobic fermentation is smoothly supplied, There is an urgent need for an apparatus and method with a low-cost and high-efficiency structure that can ferment and dry organic matter at high speed while maintaining

In one embodiment of the present invention, the plurality of double-tube structure vertical pipe (DP) and the plurality of horizontal pipe (P) can be formed to have the same diameter, for example, when the installation interval is 30 ~ 200cm , the diameter may be 2 to 40 cm, preferably 3 to 20 cm. In addition, for example, when the installation interval of the pipe is 50 ~ 180cm, the diameter may be 3 ~ 36cm, preferably 5 ~ 18cm. Also, for example, when the installation interval of the pipe is 80 to 120 cm, the diameter may be 5 to 24 cm, preferably 8 to 12 cm.

In one embodiment of the present invention, the installation interval of the plurality of horizontal pipes of the lowermost layer directly connected to the inner pipe of the plurality of double pipe structure vertical pipe (DP) and the plurality of horizontal pipes (P) of the upper layer is the plurality of the upper layer In consideration of the smooth flow of air supplied to organic matter from a plurality of branch holes installed downward in the horizontal pipe of

For example, when the diameter of the branch hole is 0.8 to 1.2 cm, it may be 12 to 24 cm, preferably 4 to 6 cm. In addition, in order to minimize clogging of the vents with accumulated organic matter, a vent pipe is coupled to all vent holes, and the vent pipe has a shape with or without a bent portion, and the distal end may be oriented toward the bottom of the fermenter.

In one embodiment of the present invention, a cap (C) is provided at the upper end of the vertical pipe (DP) of the double pipe structure as shown in FIGS. 2 to 5, and the cap (C) is the vertical pipe. It performs a function of distributing the air supplied through the inner pipe (DPI) to the outside of the external pipe (DPO) of the vertical pipe and the lower external part of the cap. In addition, the cap also functions to prevent the inflow of organic matter deposited in the fermenter (R).

The shape of the cap (C) is not particularly limited, but as shown in FIGS. 3 and 4 , a shape in which the diameter gradually increases from the top to the bottom may be preferable. The shape of such a cap may be, for example, a hollow hemispherical shape. This type of cap allows organic matter supplied from the top of the fermenter to naturally flow down through the inclined surface of the cap.

In addition, the lower end of the cap (C), as shown in Figure 9, by having a larger diameter than the diameter of the outer diameter (DPO) of the vertical pipe (DP) of the double pipe structure, the inner pipe of the double pipe structure ( The external air introduced through the DPI) can be naturally supplied to the upper organic part through the space formed between the cap (C) and the exterior (DPO).

In one embodiment of the present invention, at least one venturi pipe structure for improving the inflow rate of external air is provided in the vertical pipe (DP) inner pipe (DPI) of the double pipe structure, as shown in FIG. 10 . can In addition, the inner pipe of the vertical pipe (DP) of the double pipe structure is formed in a closed structure with no divergence on the outer wall so that a vertical upward airflow is formed by a stack effect up to the uppermost layer where the high temperature is maintained due to the oxidation heat of aerobic fermentation. do. In addition, one or more venturi tube structures may be provided inside the inner tube.

Aerobic fermentation carried out in the fermenter (R) of the unpowered organic material high-speed fermentation device of the present invention generates heat of oxidation, and when aerobic fermentation reaches its peak, the temperature inside the fermenter (R) rises to 60 ~ 75 ℃. As such, the high temperature is formed in the upper air due to the heat of oxidation of the organic matter accommodated in the fermenter (R). Therefore, the inner pipe (DP1) of the vertical pipe of the fermenter (R) has a temperature difference between the air at the upper part and the external air flowing in from the lower part. occurs Therefore, due to this temperature difference, as shown in FIG. 8, external air is naturally introduced through the horizontal pipe (P) of the lowest layer, and the external air introduced in this way is the vertical pipe (DP) of the double pipe structure. It rides on the inner tube (DPI) and forms an updraft as it rises. As shown in FIG. 9 , this upward airflow is blocked by the cap (C) installed at the upper end of the double structure and turns downward to flow downward along the vertical pipe exterior (DPO) of the double pipe structure. . In addition, a portion of the updraft may be uniformly supplied to the organic matter accommodated in the fermenter through a branch hole formed between the cap (C) and the exterior (DPO) of the vertical pipe.

Specifically, as the temperature of the air inside the fermenter R rises due to oxidation heat generated during aerobic fermentation, a temperature difference is formed with the outside air introduced through the inner pipe DP1 of the vertical pipe. At this time, due to the stack effect, etc., external air at room temperature of 15 to 25 ° C. through the inner tube of the double structure vertical pipe quickly forms an upward airflow to the uppermost part where the high temperature of 60 to 75 ° C is maintained. In addition, a venturi tube formed in the inner tube accelerates the flow of the updraft to promote the inflow of air.

In the non-powered high-speed fermentation apparatus of the present invention, the no-power state without a power unit means a state in which any mechanical system requiring power, such as a stirrer, a blower, a warm air machine, and a motor, is not equipped. As described above, in spite of the non-powered high-speed fermentation apparatus of the present invention, the smooth supply of air required for aerobic fermentation is possible, and organic matter is fermented at high speed while preserving the oxidation heat generated in the fermentation household and maintaining proper moisture. In addition, it is possible to dry and transport organic matter that is being fermented at high speed.

In addition, the high-speed fermentation method of the organic material of the present invention is

(a) an organic material pretreatment step of preparing an organic material having conditions suitable for aerobic fermentation in carbon nitrogen ratio (C/N ratio), pH, and water content;

(b) adding the pre-treated organic material to the fermenter of the unpowered organic material high-speed fermentation apparatus;

(c) fermenting organic matter by sunlight supplied by the transparent sidewall and transparent upper cover of the high-speed fermentation apparatus for unpowered organic matter, and oxygen supplied by natural air circulation by vertical and horizontal piping; and

(d) dismantling the high-speed non-powered organic material fermentation apparatus for the organic material on which the fermentation has been completed, or discharging the organic material to the outside of the fermenter by opening the bottom surface.

In the (a) pretreatment step, the carbon content ratio (C / N ratio) means the ratio of organic carbon (C) to total nitrogen (N), and microorganisms use carbon (C) as an energy source in fermentation activity, Nitrogen (N) is used as a nutrient source. The carbon content of organic matter best for the fermentation activity of microorganisms is 20~25, the average carbon content of microorganisms is about 8~12, and the average carbon content of organic matter after aerobic fermentation and decomposition activity is completed is 8~ the same as the average carbon content of microorganisms. about 12. Therefore, mixing organic matter with a carbon content suitable for aerobic fermentation is also the most important pre-treatment process for high-speed fermentation.

The pH range suitable for the fermentation activity of microorganisms in the pretreatment step (a) is 5.5 to 8.5. In general, weak acidity is maintained in the initial stage of aerobic fermentation, and as the fermentation proceeds actively with sufficient oxygen supply, ammonia (NH ₃ ) gas is generated in the nitrogen component of organic matter, and ammonium ions (NH ₄ ⁺ ) remain and become weakly alkaline. In addition, when the carbon content of the organic material is higher than the appropriate level, anaerobic fermentation occurs due to a lack of nitrogen, and the pH may maintain weak acidity due to the production of organic acid. Therefore, the pH change due to the aerobic fermentation of organic matter can be used as an indicator whether the carbon nitrogen ratio and oxygen supply suitable for aerobic fermentation of organic matter are being properly supplied.

In the pre-treatment step (a), the moisture content of organic matter is very important in order for microorganisms to actively perform aerobic fermentation. If the moisture content in the organic matter is less than 30%, the activity of microorganisms is low due to lack of fluidity. Therefore, the moisture content of organic matter should be 55~65% to maximize the activity of microorganisms in the optimal state.

In one embodiment of the present invention, in step (b), the soil microbial culture solution may be further added in an amount of 1 to 10 parts by weight based on 100 parts by weight of the organic matter.

In the high-speed fermentation method of organic matter, the photosynthetic bacteria participating in the fermentation family are bacteria that receive solar energy and photosynthesize to make carbohydrates and live on their own. plays a role In addition, it can grow in both aerobic and anaerobic conditions, and because it grows using odorous substances such as carbon dioxide (CO ₂ ) and ammonia (NH ₃ ) gas as food, it has an excellent effect in removing odors generated by fermentation of organic matter. It has a physiological function to purify the growth environment of

Hereinafter, the present invention will be described in more detail through examples. However, the following examples are provided to explain the present invention in more detail, and the scope of the present invention is not limited by the following examples. The following examples can be appropriately modified and changed by those skilled in the art within the scope of the present invention.

Here, the sensory test of the entire aerobic fermentation process and the real-time test values such as C/N ratio, pH, and temperature were calculated as the average value of five points, including four points on the upper, lower, left, and right edges of the inside of the fermenter and one point in the deep part.

In addition, in order to verify the completion of fermenting, both of the internationally used mechanical measurement methods were applied in accordance with the judgment standards set by the Act on the Management and Use of Livestock Manure to measure the fermenting degree throughout the aerobic fermentation process.
