Hereinafter, a process and system for integrated treatment of food waste according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 7, the integrated treatment process proposed by the present invention is a process capable of treating drinking water and food waste in a single process.

That is, the integrated treatment process includes a first step (1) of mixing food waste containing solids and drinking water and ultra-high temperature microorganisms (YM medium); A second step (3) of fermenting food waste and YM medium in a fermentation tank (6); A third step (5) of stirring and completing the fermented product; A fourth step (7) of deodorizing the odor generated in the fermentation tank (6); It includes a fifth step (9) of sorting and packaging the final fermented product.

In more detail,

In the first step (1), in the fermentation tank 6, food waste water or food waste mixed with solids are mixed with each other. At this time, organic wastes such as sewage sludge, livestock manure, and alcoholic sludge are mixed as well as food waste.

This fermentation tank 6 is divided into a plurality of partitions 11 as shown in FIGS. 2 and 3 to store and mix food waste. In addition, fermentation can be carried out more efficiently by arranging the diffuser 13 at the bottom of the fermentation tank 6.

At this time, the diffuser 13 may be disposed in various forms, and thus may be disposed in a vertical line shape. Of course, it is also possible in a zigzag or horizontal shape in order to increase the aeration efficiency.

In this way, after storing food waste in the fermentation tank 6, YM bacteria, which are ultra-high temperature microorganisms, are added and mixed.

YM bacteria is named Hyperthermophile in English, and is also called as hyperthermophile (極好熱菌) or archaebacteria in Korean.

The YM bacteria are aerobic super thermophilic bacteria that act and move under ultra-high aerobic conditions of 85 to 110°C, and hygienically and quickly ferment and decompose all organic wastes such as food waste, sewage sludge, livestock manure, alcoholic sludge.

In the fermentation and decomposition process, heat-resistant enzymes such as protease, collagenase, and lipase produced by ultra-high temperature microorganisms rapidly decompose non-degradable proteins and lipids, which are non-degradable organic substances that general aerobic microorganisms such as keratin of livestock carcasses cannot decompose.

The growth temperature of YM bacteria is around 85~110℃, which is significantly different from the growth temperature of general aerobic fermentation bacteria around 55℃. Due to this high temperature, the decomposition effect of food waste is excellent and the reduction rate is excellent. The killing effect of pathogenic bacteria and viruses is also excellent. In particular, it is a permanent resource circulation system that has excellent odor removal, reduces waste by more than 85%, and recycles 100% of the final product.

The ultra-high temperature microorganisms used in the present invention do not proliferate below 50°C, and are super thermophilic bacteria belonging to the genus Caldothrix that can proliferate above 80°C. Preferably it belongs to the Cardtrix Satsumae (Caldothrix Satsumae), most preferably belongs to the Cardtrix Satsumae (Caldothrix Satsumae) YM081 (FERM BP-8233) strain.

Details of the Cardothrix Satsumae YM081 (FERM BP-8233) are described in Patent No. 10-0702258.

Specifically, a bacterium named caldothrix satsumae, YM081 bacterium in Kardtrix Satsumae was deposited with the Patent Biological Deposit Center of the Institute for Industrial Technology Research, an independent administrative agency, and the accession number FERM P-18598 was given. Then, after that, it was transferred to the international deposit, and the accession number FERM BP-8233 was assigned.

In addition, an example of an infectious nucleotide sequence based on the nucleotide sequence of 16Sr DNA of Cardothrix Satsumae YM081 (FERM BP-8233) is described by sequence number 1 in the following sequence table.

In this way, after mixing food waste in which food waste water or solid content is mixed with each other, YM bacteria, which is an ultra-high temperature microorganism, are added and mixed.

Then, after the first step (1) is completed, the second step (3) proceeds.

In the second step (3), the food waste and YM bacteria are mixed in the fermentation tank 6 and fermented for a certain period in a static state.

At this time, there are various methods of mixing and fermenting YM bacteria into food waste, and fermentation proceeds by mixing food waste and YM bacteria in a fermentation tank 6 divided by a plurality of partitions 11 and storing them for a certain time.

At this time, if necessary, fermentation can be carried out more effectively by injecting a certain amount of air through the air diffuser 13.

In this way, after the second step (3) is completed, the third step (5) proceeds, and the mixture being fermented in the fermentation tank 6 is stirred.

The method of stirring the mixture may be carried out by transferring the mixture stored in the partition structure several times using various bars and heavy equipment such as a payloader.

Of course, in addition to this method, a stirrer may be used.

A conventional stirrer has a structure in which stirring blades are disposed on the upper side of the fermentation tank 6 and rotated by a motor.

Therefore, while the stirring blade rotates, fermentation proceeds more effectively by mixing food waste and YM bacteria for a certain period of time.

After the third step (5) is completed, the fourth step (7) proceeds. In this step, the odor generated in the fermentation tank 6 is deodorized and removed.

That is, the malodor is removed by inhaling the malodor inside the fermentation vessel 6 by the deodorizing unit 10 connected to the fermentation vessel 6 and deodorizing it.

This deodorization unit 10, the base 12 and; A first condenser 14 disposed on one side of the base 12 to form a swirling flow of gas sucked through the intake pipe L1 to perform primary solid-liquid separation; A second condenser (16) for performing secondary solid-liquid separation by forming a swirling flow in the gas discharged from the first condenser (14); A cyclone unit 19 disposed between the first condenser 14 and the second condenser 16 to rotate the gas discharged from the first condenser 14 and supply it to the second condenser 16; A deodorizing tower 18 for removing odors by sequentially passing the gas that has passed through the second condenser 16 through the multi-layered filter layers 30, 32, and 34; It includes a blower 20 disposed between the second condenser 16 and the deodorizing tower 18 to supply the gas discharged from the condenser to the deodorizing tower 18.

In the deodorization unit 10 having such a structure,

The first condenser 14 is provided with an intake fan f at the top, and the intake fan f is connected to the fermentation tank 6 through an intake pipe L1. Accordingly, when the intake fan f is driven, the gas containing odor from the fermentation tank 6 may be sucked into the first condenser 14 through the intake pipe L1.

In addition, the gas flowing into the first condenser 14 contains water vapor and odor components, and the odor components flow downward and reach the first barrier plate 26 provided at the bottom.

The first barrier plate 26 has a propeller shape and is rotatable by a motor.

Accordingly, when the first barrier plate 26 is driven, dust and moisture contained in the gas are discharged to the outside through the lower first outlet 27, and the gas containing the remaining components rises.

At this time, the first outer pipe 28 connected to the lower portion of the cyclone unit 19 is disposed on the lower outer side of the first condenser 14 to surround the outside of the first condenser 14, and the first outer pipe ( 28), a flow path through which gas flows is formed.

Accordingly, the gas rising from the first barrier plate 26 forms a swirling flow along the flow path and rises to reach the cyclone portion 19.

At this time, when the gas forms a swirling flow and rises, the high density foreign matter is pushed outward and falls along the inner wall surface of the first outer pipe 28, and only the relatively low density gas rises.

In addition, the cyclone unit 19 is connected to the first condenser 14, the first cyclone pipe 21 for first applying a centrifugal force to the gas rising from the first obstruction plate 26; A second cyclone tube 22 connected to the second condenser 16 and secondly applying a centrifugal force to the gas discharged from the first cyclone tube 21 to discharge it into the second condenser 16; It includes a connection pipe 23 connecting the first and second cyclone pipes 21 and 22.

The first cyclone tube 21 surrounds the outside of the first condenser 14 and has a circular structure. Accordingly, the gas raised from the first barrier plate 26 is rotated to generate a centrifugal force and discharged to the second cyclone tube 22 through the connection tube 23.

The second cyclone tube 22 has the same structure as the first cyclone tube 21, and has a circular structure surrounding the outside of the second condenser 16, thus, in the first cyclone tube 21 The discharged gas collides with the inner wall of the second cyclone tube 22, and in this process, a swirling flow is formed to go downward along the inside of the second outer tube 25 provided outside the second condenser 16. Flow.

A second barrier plate 31 is provided under the second outer tube 25, and the second barrier plate 31 has the same structure as the first barrier plate 26, and has a propeller shape.

Therefore, when the second barrier plate 31 is driven, dust and moisture contained in the gas flowing to the inner bottom of the second condenser 16 are discharged to the outside through the second outlet 24 at the bottom, and the remaining components This contained gas rises along the inside of the second condenser (16).

The second condenser 16 has one side of the discharge pipe L2 connected to the top, and the other side of the discharge pipe L2 is connected to the blower 20.

Accordingly, the gas that has risen along the inside of the second condenser 16 may be supplied to the blower 20 through the discharge pipe L2.

The blower 20 is disposed on the duct 29 connecting the second condenser 16 and the lower portion of the deodorization tower 18 to supply the gas discharged from the second condenser 16 to the deodorization tower 18.

Accordingly, the gas discharged by the blower 20 flows into the lower portion of the deodorization tower 18 and rises to undergo a deodorization process.

The deodorization tower 18 removes malodorous components of the introduced gas by having at least one filter layer 30, 32, and 34 disposed therein.

This deodorizing tower 18 includes a main body 17; A duct 29 disposed under the main body 17 and through which gas injected by the blower 20 is introduced; It includes at least one filter layer (30, 32, 34) stacked inside the body 17 to remove odor components.

The gas supplied through the duct 29 rises from the inner bottom of the main body 17, and in this process, odor components may be removed in the process of sequentially passing through the filter layers 30, 32, and 34.

These filter layers 30, 32, 34 can be composed of various materials capable of removing odor components, for example, YM bacteria layer, rice husk layer, activated carbon layer, charcoal layer, adsorbent layer, zeolite layer, silica gel layer, alumina layer , Clay layer, diatomaceous earth, may be composed of bentonite.

As described above, the YM bacteria layer is also called extremely thermophilic bacteria or archaebacteria, and acts and moves under ultra-high temperature aerobic conditions of 85~110℃, and all organic wastes such as food waste, sewage sludge, livestock manure, alcoholic sludge, etc. Can be disassembled. Therefore, the gas containing the odor can be rapidly decomposed by passing through the YM bacteria layer, thereby removing the odor.

The rice husk layer is a filter layer formed from the husk of rice, and odors contained in the gas can be removed while the gas passes through the rice husk layer.

The active carbon layer (active carbon) is a material with strong adsorption and most of its constituent materials are carbonaceous, and is used as an adsorbent to absorb gas or moisture, or as a decolorizing agent.

Charcoal refers to a solid product formed when wood is heated by cutting off the supply of air or heating it with very little air.

The adsorbent (吸着劑) is a solid material with a large surface that molecules can adsorb, which is a component necessary for adsorption, a phenomenon in which gas or liquid molecules adhere to the solid surface.

The zeolite layer refers to a mineral in which an alkali metal and an alkaline earth metal are combined with an anion produced by the combination of aluminum oxide and silicic acid oxide. These zeolites have a molecular sieve effect of selectively adsorbing polar substances or unsaturated hydrocarbons by cations located in the crystal structure, and because they have pores of a certain size, they selectively pass through smaller molecules than these.

The alumina layer is a compound of aluminum and oxygen, and is industrially referred to as alumina. Formula Al2O3. The molecular weight is 101.96. Used as an antacid and adsorbent.

The size of the particles is generally about 10-200 μm, and may be coarse depending on the particle size, and may have a low density when the pores are large. The general chemical composition of dried diatomaceous earth is about 80-90% of silica, about 2-4% of alumina, and about 0.5-2% of iron oxide.

Bentonite refers to clay mainly containing montmorillonite, a mineral belonging to the monoclinic system having a crystal structure like mica.

At least one or more of these filter layers 30, 32, and 34 may be stacked, or two or a plurality of filter layers 30, 32, and 34 may be stacked in any combination.

In addition, the gas supplied to the interior of the deodorization tower 18 through the duct 29 may remove odor components contained in the gas in the process of sequentially passing through the filter layers 30, 32, and 34 from the bottom.

In addition, this odor removal process may be performed only once, but may be repeated multiple times. That is, the gas discharged from the deodorization tower 18 is injected into the deodorization tower 18 again to sequentially pass through the filter layers 30, 32, and 34 to further remove odor components.

On the other hand, after the fourth step (7) is completed, the fifth step (9) of selecting and packaging the final fermented product proceeds.

In the above step, the final fermented product is used as a functional compost or used as a fueled fermented material.

On the other hand, as a result of testing whether or not odor substances were detected in the final fermented product according to the present invention, it was as follows.

As shown in Table 1, in the case of the complex odor, when the inflow value of the deodorizer is 448, the outflow value is 208, which is less than the reference value of 500, so that the odor is effectively removed. At this time, the site boundary value is 5.

In addition, 12 components designated as malodorous substances were also analyzed.

In the case of sulfur compounds, the sample air collected by the indirect collection box is analyzed using TD/GC/FPD. In the same way, a calibration curve is prepared by injecting a sulfur compound standard gas, and the area of the analysis data of each sample is converted into the formula, and the final concentration of the sample is determined using the area injected into the device. If the concentration of the sample is too high, dilute and repeat the analysis. If the concentration of the sample is too low, increase the injection volume to make a peak of a certain size appear to fall within the concentration range of the standard gas.

In the case of an aldehyde compound, a certain amount of atmospheric sample from the collected sample bag is adsorbed onto a DNPH cartridge, and the adsorbed atmospheric sample is eluted and analyzed using an HPLC instrument.

In the case of styrene, the collected atmospheric sample is adsorbed on an adsorption tube and analyzed using TD/GC/MS. The standard sample is analyzed by the same method, and the concentration is obtained by a predetermined method by substituting the volume of the sample adsorbed on the obtained calibration curve and the area obtained by instrument analysis.

In the case of ammonia, the sample is taken at a rate of 10 L/min with an absorbent solution in the field to determine the concentration. The ammonia collected in the absorbent solution is brought to the analysis chamber and the absorbance is measured using ultraviolet (UV) light. Measure the absorbance of the standard substance in the same way to obtain a calibration curve, substitute the absorbance of the sample into the obtained calibration curve, and convert the volume of the collected sample into the standard volume according to temperature and air pressure, and calculate the concentration in a certain way.

In the case of TMA, samples are collected in the same way as ammonia in the absorbent liquid at the site. The collected sample is analyzed using GC/FID using SPME, and the concentration of the sample is calculated using the calibration curve of TMA obtained by the same analysis method.

Meanwhile, the physical properties of the final fermented product treated in this integrated treatment fusion system were analyzed physicochemically as follows.

In FIG. 8, a graph of fermentation temperature is shown, and fermentation temperatures during a process of fermenting food waste and YM medium in a fermentation tank 6 were measured.

The growth temperature of YM bacteria is around 85~110℃, and as a result of measuring every year, the lowest temperature was 95℃ and the highest temperature was 109℃. Considering that the fermentation temperature of general aerobic fermentation bacteria is 55℃, it can be seen that the fermentation temperature is quite high.
