Naturally flowing down and stored in the liquid storage tank installed in the; The liquid fertilizer stored in the liquid fertilizer storage tank is a method of manufacturing energy and composting (liquid fertilizer) of organic waste consisting of a submersible aeration pump installed in the liquid fermentation tank to remove odors by aerobic method and then producing high quality liquid fertilizer and utilizing them in organic farming It is about.

Today, organic waste muffles use energy in a variety of ways, using biogas generated from high concentrations of organic materials with high organic content due to changing times.

Recycling of food waste includes fueling, feeding, and composting, but it is difficult to separate foods. Perishable. Concerns about the development of pathogens. Livestock damage due to foreign objects. There are difficulties due to the imbalance of nutrients, fuelization is a substantial investment and reprocessing facilities must be parallel for complete treatment, there was a problem that requires a high operating technology.

As a means to dispose of food wastes with these problems, composting has been carried out using conventional techniques. As a result, most food wastes have been concentrated on the increase in throughput or treatment efficiency rather than the quality of the final product and its use. The compost used was produced as an uncomposed compost and was not used in farmland, but rather caused secondary environmental pollution.

In particular, food waste has a high salinity and high moisture content compared to other compost raw materials, and is mixed with other compost raw materials rather than direct composting.

In the present invention, by improving the security of these problems by treating the basic principle and form-specific technology according to the composting (liquid) production for alternative energy production and environmentally friendly agriculture using food waste in the anaerobic method has the following advantages.

Methane Production (Electricity Production / Boiler Use)

Low excess sludge generation (5-20% of exhalation process)

High-quality liquid fertilizer production

High rate treatment of high concentration organic matter (5-10 times)

Low investment cost / low running cost

No oxygen supply

Low Nutrient Requirements (N.P)

Low site requirements

Biodegradation of non-degradable materials under aerobic conditions

Degradable of Chlorindted / Halohenated Organics

The outstanding effect of creating ecological and economic benefits from energy conservation is obtained.

The present invention has been proposed to supplement and improve the conventional problems. When the organic wastes are anaerobicly matured, it is necessary to maintain the density of acid-producing bacteria and methane-producing bacteria in the first step, but methane-producing bacteria have weak environmental adaptability compared to anaerobic acid-producing bacteria. Therefore, if the methane bacteria are not inoculated, only acid production is promoted and anaerobic decomposition does not proceed. Therefore, after the digestion tank is installed, the first step is to start the anaerobic maturation. About 20% of the volume should be put into the digester and operated as mother liquor. Actually, the anaerobic digester is not widely available, so it takes a lot of time and economic loss to receive the mother's fluid.

In the present invention, in order to improve such a problem, as a useful microbial group for producing an antioxidant substance, ASK fermenter, which is a photosynthetic bacterium of yeast, lactic acid bacteria, actinomycetes, and filamentous bacteria, is used as a mother liquor by blending ASK per kg of organic matter in a screw-type grinding step , In order to prevent the high viscosity of the organic matter in the anaerobic decay tank, the formation of a layer to reduce the decomposition efficiency of the solution in the digestion tank is required in the present invention 15 days ASK fermentation agent in the screw grinding step without a separate stirring device When ASK 5kg per 1㎥ of organic matter is added to the digester, methane production is increased and organic decomposition rate is accelerated, and the housing period is generally 20 ~ 25 days at 55 ℃ and shortened to 15 days. To minimize the installation area of the digester by reducing the volume of anaerobic digester You can get an expulsive effect.

In addition, by installing a dual fuel boiler using biogas generated from anaerobic digester, it is used as a heating means for the digester, and a fuel required for operating the digester facility by connecting a dual fuel biogas engine that can simultaneously obtain electricity and heat to the cogeneration plant. When composting (liquid) of the waste liquid treated by the anaerobic method and generating economic benefits that can handle the electricity itself and electricity, many kinds of odors such as lower volatile fatty acids and sulfur compounds are generated.

In the present invention, by increasing the amount of dissolved oxygen in the aerobic storage tank as a means to remove the odor to promote decomposition of organic matter and to remove the odor, and to suppress the precipitation and scum formation of solids by installing an underwater aeration pump in the liquid aeration tank 55 ℃ Continuous supply of 1 ~ 5㎥ of air per hour based on the liquid ratio of 1㎥ at the temperature of can remove odors.The odor emitted to the outside is installed with a deodorizer to prevent secondary environmental pollution to produce good liquid ratio. It is about the technology used in organic farming.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing the overall configuration of the method for producing an energy and liquid ratio of the organic waste described in accordance with an embodiment of the present invention,

When food waste is brought into the treatment plant, foreign substances such as bottles of vinyl metal bottles are sorted on the screen (2), and the particle size is crushed to 1.5 mm or less in the screw crusher (3), and 10 kg of ASK fermentation agent is added per 1 ㎥ of food waste. By the conveying conveyor (4) is introduced into the inlet (5) of the anaerobic digester body (1).

The injected food waste is stored in the liquid rain storage tank 22 through a hydrolysis tank 6, an acid formation tank 7, a methane formation tank 8, and finally, a liquid feed pipe 20 separately installed outside the digestion tank.

Biogas generated in the anaerobic digester body (1) is collected in the biogas storage tank (25), a dual fuel boiler (29) is installed using the biogas and used as a heating means of the digester, and cogeneration (26) By connecting Dual Fuel Biogas engine which can get electricity (27) and heat (28) at the same time, it can process fuel and electricity necessary for the operation of digester by itself, and the odor of waste liquid (liquid ratio) generated after anaerobic fermentation By installing a submersible aeration pump 21 in the liquid storage tank 22 as a means for removing the odor to remove the odor is a method of producing a good liquid ratio (24).

The outline of the anaerobic digester according to the present invention is as follows.

{Example}

Outline (10㎥ / day standard)

Configuration Underground type / reinforced concrete tank Digester specification   13000 (L) × 9000 (W) × 3500 (H) Digestion tank total capacity (㎥)   410 (in 40 days) Effective Volume (㎥)   150 (15 days) HRT   15 days Daily throughput   10㎥ / day Digester type   3-stage system + liquor reservoir Operating temperature   55 ℃ ± 1 Agitation method   ASK Fermenter 15 days / 1 time Use bio gas   Boiler / CHP (Cogeneration) Gas storage tank   Dry type (100㎥) Generator capacity   37Kw Heat exchange method   Dual Fuel type OLR   0.7 to 3.5 kg VS / ㎥.d Food injection method   2-4 times / day Liquid yield   5㎥ / day

In the present invention, the main body 1 of the anaerobic digester is installed with a reinforced concrete tank in the basement with a standard of 13000 (L) × 9000 (W) × 3500 (H), and the total volume of 410㎥ is effective as a daily treatment capacity of 10㎥ / day. The volume is set to 150㎥, the inside of which is divided into a hydrolysis tank (6), acid-forming decomposition tank (7), methane production tank (8) will be described in more detail for each configuration step as follows.

The specification of the hydrolysis tank 6 according to the present invention is composed of 4000 (L) × 9000 (W) × 3500 (H), and 3000 from the top to the bottom between the hydrolysis tank 6 and the acid-forming tank (7) A barrier rib of ㎜ is installed and the lower end portion has a conveyance passage 10 of 500 mm so that the organic material is transferred to the acid forming tank (7).

In the hydrolysis tank (6), the first step of anaerobic digestion, many organic compounds (carbohydrates, proteins, lipids) are decomposed by the hydrolytic enzymes of hydrolyzed bacteria and fermented bacteria. Polysaccharides, carbohydrates, and protein fat lignin Complex Organies such as cellulose are decomposed into monomers or oligomers such as soluble sugars, alcohols, fatty acids, amino acids, and polypeptides. After the input of the waste liquid or sewage sludge of the anaerobic digester, there was a problem that a certain amount of food waste should be operated every day after about 30 days.

In the present invention, when 10 kg of ASK fermentation agent is added per 1 m 3 of food waste in the shredding step (3), the fermentation proceeds after 72 hours, and a certain amount of food waste is added daily to operate normally. There is an advantage.

The acid formation decomposition tank 7 is composed of 4000 (L) x 9000 (W) x 3500 (H), and is formed from the top to the bottom between the acid formation decomposition tank (7) and the methane forming tank (8). 2000 mm bulkheads 9 are installed in the wall, and 1000 mm bulkheads 11 are installed between the lower end and the upper end, and the remaining space part 500 mm is composed of the transport passages 12 of the organic waste.

In anaerobic digestion, the acid formation step is Acid Bacterate which decomposes the dissolved low-molecular substance produced by the hydrolysis step by acid producing bacteria into Prpoionate Butyrate, and the microorganism that decomposes the organic acid produced by these microorganisms with acetic acid is Acetoneic Bacteria. to be.

Acid-producing bacteria have faster growth rate and substrate utilization rate than methane-producing bacteria and are more stable to environmental changes.

The acid formation step is divided into hydrolysis-produced monosaccharides to propionic acid or butyric acid, followed by acetic acid, which is finally degraded to acetic acid using propionic acid.

In this process, the substrate generated during the acid formation process is decomposed to produce hydrogen acetate gas and carbon dioxide, which are methane-producing substrates.

Acetogenic reactions occur only at very low conditions, such as 10 ^-4 to 10 ^-5 atm, which is possible because the hydroenophilic methanogenic Bacteria family consumes hydrogen. That is, the microorganisms at all stages are required to agitate the solution in the acid formation step in the acid formation step, in the present invention, the fermentation agent ASK per 1㎥ of food waste in the food waste shredding step (3) without the need for a separate stirring device of the solution If 5kg is added once every 15 days, the decomposition rate is accelerated at the temperature of 55 ℃ to increase the amount of methane generated and the housing period is shortened to 15 days, which reduces the volume of anaerobic digester, thereby minimizing the installation area of digester. Phosphorus effect can also be obtained.

The size of the methane forming tank 8 consists of 5000 (L) × 9000 (W) × 3500 (H), and the liquid ratio generated daily by connecting ø100 PVC pipe to the middle point of the methane producing tank 8 is natural. To flow into the liquid storage tank 22 to be stored.

In addition, the intermediate passage adjacent to the acid-forming decomposition tank (7) and the hawk generation tank (8) has an access passage (16) of 5000 (L) × 2000 (W) × 3500 (H) and 1500 (L) × 1500 (W). By attaching the transparent glass 14 to the naked eye to check the formation process, and if the oxidized fiber and foreign substances accumulated in the food waste is a obstacle to the production of methane as a means for discharging the foreign matter to the outside A drain valve 15 of Ø150 is attached to the bottom of the methane forming tank 8.

In the present invention, when the temperature of the digestion tank is maintained at 55 ℃, in the crushing step by the crushing (3) when 5kg of ASK fermenter per 1㎥ of food waste is periodically added once every 15 days, the experimental results generally methane forming tank Biogas is 0.4-2.9 kg VS / m3.d in (8), but 0.7-3.5 kg VS / m <3> when ASK fermentation agent is added. d has a characteristic of increasing the amount of coal generation.

In addition, the liquid storage tank 22 is made of a high-density polyethylene-based PE synthetic resin (PDF), and the wall is made of a synthetic resin having a high resistance to harmful gases generated from food wastes treated by anaerobic methods. Reinforce the construction of the C-shaped steel plated on the outside of the synthetic resin wall to withstand the pressure.

The structure of the storage tank 22 is coated and sealed with a thick PE sheet to prevent leakage of the liquid rain, and the galvanized iron plate on the outside to prevent deterioration of the plastic by solar ultraviolet rays.

The liquid storage means is a method of connecting the Ø 100 PVC pipe to the liquid storage tank 22 at the upper and middle portions of the methane forming tank 8 so that the liquid rain 24 generated daily flows naturally.

When organic wastes are fermented anaerobicly, many kinds of odorous components such as lower volatile fatty acids and sulfur compounds are generated in the waste liquid (liquid ratio) .In the present invention, the amount of dissolved oxygen is increased in the liquid storage tank 22 by aerobic method as a means for removing odors. In order to promote decomposition of organic matter, remove odors, and suppress solid matter precipitation and scum formation, an aeration pump 21 is installed in the liquid rain storage tank 22. The continuous supply of 1 to 5 m 3 of air has the effect of completely removing the odor. At this time, the odor generated during the underwater aeration treatment is to prevent the secondary environmental pollution by installing a deodorizer (23).

In the biogas storage tank 25, since the amount of gas generated in the anaerobic digester varies greatly, in order to use digestion gas as a fuel, a digestion gas storage system is required to control supply and demand.

General gas storage capacity is suitable for 25 to 35% of daily gas generation. Biogas storage and use facilities always maintain a positive pressure to prevent the formation of explosive gases due to inflow of air to the outside.

In the present invention is easy to maintain and in particular in winter, the water for sealing does not freeze so that the up and down movement of the gas holder is easy to use dry type.

Example 1 Biogas Storage Tank Design Factors

Item value Kinds Dry type Gas storage capacity 25 ~ 35% (6 ~ 8hrs) of daily gas generation Gas holder internal pressure 150 ~ 250mmAq Anticorrosive coating hot-dipped gavanizing / fusion bonded epoxy Monitoring equipment Manometer, Water Level Meter, Gas Analyzer Pressure safety device pressure / vaccum relief valve (200 ~ 250mmAq setting) Gas Stabilizer Flame trap & Arresters

On the other hand, the most commonly used heat source in the anaerobic digestion tank is a boiler 29 using digestion gas, and the deterioration yield is 70 to 80%.

Digestive gases, depending on their quality, need to be cleaned before the boiler combusts in the engine.

If hydrogen sulfide (H ₂ S) is more than 100ppm in the extinguishing gas, it will seriously damage the boiler or engine.To prevent corrosion, clean H ₂ S before combustion or maintain the boiler water temperature at 100 ° C. It should be kept at 177 ~ 204 ° C to prevent acid concentration.

In the present invention, the dual fuel type biogas boiler is heated accordingly.

In the present invention, the heat exchanger 31 uses an external heating method for exchanging heat between the substrate and hot water by double contact with the outside of the digester.

That is, hot water passes through the waste water in the inner tube and heat exchanges in the outer tube. At this time, in order to maximize the heat exchange rate, it must flow in the opposite direction.

The hot water and waste water infusion pump uses an accelerator pipe that can be used semi-permanently on both side walls and the bottom of the anaerobic digester main body 1 and interlocks with the heat exchanger so that the heat exchange circulation pipe 32 operates at the same time when the hot water infusion pump operates. Configure.

In cogeneration 26 according to the present invention, a dual fuel diesel engine for electric power generation is a Mechenical-Injection diesel engine settled in a gas mixing device or an air inlet, instead of simply being injected with air. Compressed inside the cylinder, a small amount of diesel oil is injected and ignited. Diesel fuel injected from the calorie side consumes 5-10% of the total engine power.

In the present invention, in order to maximize energy recovery rate, cogeneration 26 is used to obtain electricity 27 and heat 28 at the same time.

In the present invention, the status of the type of substrate, applied load, pH, alkyrido, toxic substance and influence factors of biogas generation, digestion temperature, residence time, C / N ratio solid concentration, etc. are frequently checked in the present invention. In order to control the influence factor by remote monitoring 33 to build a PLC monitoring system to perform unattended / automatic operation.

Referring to the function and role of the soil when using the liquid fertilizer 24 in the present invention is as follows.

(1) Effect as a source of plant nutrients

Soil corrosion has the function of supplying macro and trace elements. And the effect is different from chemical fertilizers, so it is slow and feeds the crop. In particular, during the decomposition process, carbon dioxide is released, which promotes photosynthesis of plants and supplies growth promoting substances to crops.

(2) Improvement of Physicochemical Properties of Soil

Soil corrosion has the function of supplying macro and trace elements. And the effect is different from chemical fertilizers, so it is slow and feeds the crop. In particular, during the decomposition process, carbon dioxide is released, which promotes photosynthesis of plants and supplies growth promoting substances to crops.

(2) Improvement of Physicochemical Properties of Soil

Soil corrosion has the effect of improving soil physics to prevent soil erosion by rainfall by increasing soil pore distribution by increasing soil particle size and improving permeability, water retention and breathability.

Soil corrosion has a higher cation substitution capacity than soil clay, so humus soils have a higher CEC, which improves buffering capacity. Corrosion, on the other hand, acts as a chelating agent, thus inhibiting the formation of active aluminum in the soil, preventing phosphate fixation, and promoting soil phosphate.

(3) Maintenance and promotion of biologicality and activity in soil

Increasing the amount of corrosion in the soil increases the number of small and medium organisms and microorganisms in the soil, increasing species diversity and stabilizing the biomass.

As a result, the material circulation capacity is increased, thereby enhancing biological soil circular function. In addition, the number and activity of soil microorganisms are increased to increase the ability to decompose, remove and stabilize harmful substances.

Illustrating the accumulation phenomenon of the foreign matter in the anaerobic digestion tank 1 according to the embodiment, 10 ㎥ × 365 days = 3650 ㎥ (year) is added to the digester when 10 m ³ / day of food waste.

Since 85% of food waste is water, 15% is pure organic matter and 15% of organic matter is indigestible fiber, pure organic matter is 3650m ³ × 15% = 548m ³ (year) × 15% (fiber) = 82m ³ (year ) Is accumulated in the digester for one year, and 82m ³ (year) of fiber, which is about 2.3% of the effective volume of 3650m ³ (year), accumulates in the digester and becomes an obstacle to digestion.

In the present invention, in order to improve and supplement these problems, the hydraulic switch (17) and (18) of 1000mm × 1000mm standard are installed on the top of the hydrolysis tank (6) and the acid forming tank (7), respectively, to pile up the fiber or foreign matter. Part of the accumulation of the most foreign matter including fibers in the anaerobic digestion process occurs in the step of transferring the organic material from the acid forming tank (7) to the methane forming tank (8).

As a means for improving and supplementing these problems, a 1000 mm barrier rib 9 is installed between the lower end and the upper end of the acid forming tank 7 so that foreign substances including fibers are accumulated in this part to remove the accumulated foreign substances. The sludge transfer pipe 19 of φ300 is installed between the upper end and the lower end of the acid formation tank 7 to be discharged to the outside by the circulation pump to operate the anaerobic digestion tank 1 normally.

Therefore, the present invention does not use the mother liquor, which is an essential condition when treating organic wastes by anaerobic method, as waste liquid or sewage sludge. The speed is increased, methane production is increased, and the volume of the digester is reduced, thereby minimizing the installation area of the digester, and the biogas generated from the anaerobic digester is used to match the boiler installation and the cogeneration plant. Generates high-quality liquid fertilizer after removing odor by aerobic method by installing underwater aeration pump in liquid storage tank for odor generated from waste liquid treated by economic analytic method and anaerobic method that can process necessary fuel and electricity by itself. It is effective to utilize.
