Description

Multi-Stage Long-term Stay Organic Waste Disposal Recycling System {APPARATUS OF CLARIFYING AND RECLAMATING ORGANIC WASTE WITH PROLONGED STAY PROCEDURE}

The present invention relates to an organic waste dissipation recycling apparatus for recycling organic waste such as animal waste or food waste.

Conventionally, organic waste including food waste, livestock manure, and other wastes, such as industrial wastes, have been dumped or incinerated at sea, but landfills have been discontinued since 2005 due to difficulties in securing landfills and social requests for preservation of the natural environment. Direct landfilling has been banned entirely.

As a result, organic waste such as food waste is processed through a separate treatment process by dumping the waste liquid into the East Sea or the West Sea, which generates hundreds of thousands of tons of waste liquid per year.

However, the disposal cost of waste liquids not only reaches billions per year, but also destroys the marine ecosystem by dumping high concentrations of acidic waste liquids with a pH of 3 to 4 into the ocean, and the government establishes the land priority treatment principle of land wastes. In order to protect the marine environment and the marine environment, the General Measures for Land Waste Marine Dumping Management was established, and since 2012, it has completely banned land dumping of land waste.

Therefore, it is urgent to develop a method for treating organic waste that does not generate waste liquid.

On the other hand, organic wastes can obtain biogas (methane) in the process of fermentation, and its resources are attracting attention from the viewpoint of environmental conservation and renewable energy sources.

However, the anaerobic digester for the recycling of such organic waste not only requires enormous construction costs, but also requires highly skilled professionals and has to have a separate waste liquid treatment facility to treat the generated desorbent. In addition, the current environmental law is difficult to treat the waste liquid within the effluent discharge allowance standards, which is not a realistic alternative.

Therefore, there is an urgent need for the development of a resource recycling method of organic waste that can be easily maintained and operated at low cost.

In particular, it is possible to secure alternatives to the ban on organic dumping of organic waste and land reclamation, which will take effect from 2012, and to secure carbon emission rights for clean development system (CDM) by reducing warming gas.

In addition, the organic waste is decomposed over a long period of time without additional management, and there is almost no residue, so the maintenance is easy.

Therefore, high economic feasibility, resource recycling and environmental conservation can be achieved at the same time, resulting in innovation of the environmental industry.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the multi-stage long-term residence type organic waste extinguishing resource treatment apparatus according to the present invention.

1 is a perspective view illustrating an external appearance of a multi-stage long-term residence type organic waste extinguishing resource treatment apparatus installed in accordance with the present invention, and FIG. 2 illustrates a structure of the multi-stage long-term residence type organic waste extinguishing resource treatment apparatus shown in FIG. 1. 3 is an enlarged view of the stirring vessel 100 illustrated in FIG. 2, and FIG. 4 is a conceptual diagram illustrating an operation process of the multi-stage long-term stay organic waste extinguishing resource treatment apparatus illustrated in FIG. 1.

First, as shown in FIG. 1, the multi-stage long-term residence type organic waste extinction recycling apparatus according to the present invention is embedded in the ground so that only the upper end is exposed as an indicator.

Components exposed by the indicators include an organic waste inlet 110 and a microbial inlet 120 at the lower left of FIG. 1, and a liquid inhaler 410 is installed thereon.

Meanwhile, a gas discharge valve 220, a water separator 240, and a gas cooling filler 250 are provided at an upper end of FIG. 1, and an inspection window 310 is provided at a lower end thereof.

On the other hand, as shown in Figure 2 is a multi-stage long-term residence type organic waste extinguishing resource treatment apparatus according to the present invention, the stirring tank 100, the reaction tank 200, the liquid ratio generating tank 300 and the sediment storage tank 400 sequentially It is connected to the structure, it is connected by the moving path to the right downward from the lower right of the stirring tank 100 to the lower left of the liquid rain generating tank 300.

The agitator tank 100 has an inlet 110 for injecting organic waste and an inlet 120 for injecting microorganisms, respectively, on an upper surface thereof.

At this time, the adjacent surfaces of the stirring tank 100, the reaction tank 200 and the liquid rain generating tank 300 is blocked by the partition wall except for the lower end, the sealed state is maintained for anaerobic digestion as described below. However, only the stirring tank 100 releases the sealed state when opening and closing the inlets 110 and 120. As will be described later, in the stirring tank 100, acid fermentation is mainly performed by hydrolysis and through anaerobic bacteria, and high concentration of organic matter. Since it is added, the oxygen introduced during the input is completely consumed by the anaerobic bacteria. Therefore, it does not affect the methane bacteria of the reaction tank 200 and the liquid ratio generating tank 300.

In the state buried in the ground as shown in Figure 1, the manager fills the water to a predetermined height in the stirring tank 100, reaction tank 200, the liquid ratio generating tank 300 and the sediment storage tank (400). At this time, the water level of the stirring tank 100, the reaction tank 200 and the liquid ratio generating tank 300 is naturally equal.

Thereafter, microorganisms containing strains for hydrolysis, acid fermentation and methane fermentation are added and cultured.

When microorganisms begin to be cultured, organic waste may be treated in earnest, and the manager inputs organic waste such as livestock manure, sewage sludge, and food waste into the inlet 110.

On the other hand, the organic waste is decomposed by hydrolysis and acid-fermenting bacteria, etc. without a separate stirring action, the physical properties are changed such that the viscosity is lowered, and gradually gradually downwards due to water level change and gravity triggered by the reaction tank 200 as described later. Organic waste and microorganisms introduced during the movement are naturally stirred.

At this time, it may be further provided with a separate stirring screw 130 to help the stirring process to trigger a more rapid biochemical reaction.

As shown in FIG. 2, the stirring screw 130 stirs the microorganisms and the large amount of organic waste introduced by the rotational movement and sends them down.

According to FIG. 3, the stirring vessel 100 is illustrated in more detail. The stirring screw 130 is driven by the DC motor 160, and the DC motor 160 is located in an area where power supply is not easy. It is driven by solar due to the nature of the equipment to be buried.

In FIG. 3, the solar cell array 140 is illustrated as being installed on the upper surface of the stirring vessel 100, but does not necessarily need to be the upper surface of the stirring vessel 100. It is desirable to enable this. By slightly adjusting the direction and angle of each season, it is possible to improve the light collection efficiency slightly.

Meanwhile, in order to enable driving of the motor 160 after sunset, the solar energy collected through the solar cell array 140 is converted into electrical energy and then charged with the battery 150. At this time, the battery 150 is preferably a lithium ion (Lithum Ion) or a lithium polymer (Lithum Polymer) battery due to the nature of charging and discharging every day.

The DC motor 160 rotates the stirring screw 130 by receiving power from the battery 150, and according to the existing technology of the solar cell, the DC motor 160 can directly bear the weight of the stirring screw and the weight of organic waste. Since the driving of the high-output motor is somewhat difficult, by lowering the number of revolutions of the stirring screw 130 through a separate gear box (not shown) to enable a comfortable operation. Fortunately, the stirring screw 130 does not need to rotate at high speed, and was tested with a commercially available DC motor.

On the other hand, the DC motor 160 may be manually operated by a manager by a switch not shown, but preferably, organic waste is introduced through an infrared sensor (not shown) provided in the stirring vessel 100. If the height rises above a certain height, it can be automatically driven. In this case, when the height of the injected organic waste drops below a certain height, the driving stops.

On the other hand, the injected organic waste is mixed with water, causing biochemical reactions with the microorganisms previously cultured. In the agitation tank 100, hydrolysis and acid fermentation are performed by the action of microorganisms. The pre-cultivated microorganisms are fats in organic wastes, proteins are lower fats and amino acids, and carbohydrates are substituted with monosaccharides to form hydrogen, acetic acid and lower fatty acids. And organic acids are produced. During the decomposition, a large amount of heat of fermentation is generated, which causes a considerable amount of moisture to evaporate.

By insulating the outer wall of the stirring vessel 100, it becomes possible to preserve the heat of reaction, thus further accelerating the hydrolysis and acid fermentation. At this time, it may be provided with a separate heating device (not shown) for heating the stirring tank 100 to facilitate the initial test reaction. On the other hand, it is possible to promote the fermentation and digestion reaction by supplementing the heat source by such a heating device in normal operation.

Returning to Figure 2, the reaction tank 200 is connected to the lower left side of the agitator 100 along the right downward movement path from the lower right, the lower right side of the liquid fertilizer generation tank 300 along the right downward movement path It can be seen that the connection to.

On the other hand, the bottom is provided with a concave-convex reactor 210, the concave-convex reactor 210 is made of a corrosion-resistant metal material, has a pattern in which the irregularities of the height difference is about 10mm to 20m repeatedly. Meanwhile, as shown in FIG. 2, the uneven reaction furnace 210 is inclined downward in the right direction, so that the unevenness is closer to the 'b' shape than the '∧' shape.

According to Figure 2 is connected along the moving path to the lower right from the lower right of the stirring tank 100 to the lower left of the liquid rain generating tank 300, the organic waste was stirred slowly in the stirring tank 100 by the reaction tank 200 by gravity Some move to. (However, the basic principle of moving the organic waste to the reaction tank 200 is a change in the water level according to the change in the gas pressure as described later, a significant portion is sucked into the reaction tank 200 when the water level changes.)

The uneven reactor 210 serves to keep the organic waste 1 from flowing down at a time, and the organic waste 1 stays in the uneven reactor 210 section for a long time and causes a biochemical reaction.

Monosaccharides, hydrogen, acetic acid, lower fatty acids and organic acids produced in the stirring tank 100 are decomposed into carbon dioxide, water, methane gas, etc. by methane fermentation bacteria. In the reaction tank 200, the reaction is performed for a long time by methane, thermophilic high temperature bacteria, and basophilic bacteria. Unlike in the stirring tank 100, high heat of fermentation is not generated, but a large amount of CO ₂ and CH ₄ is generated.

4 is a state in which the internal gas pressure is increased by discharging a large amount of biogas as a result of methane fermentation occurring inside the reactor 200.

The gas discharge valve 220 does not discharge the gas until it reaches a predetermined gas pressure or more. When the gas layer inside the reaction tank 200 expands, the organic waste on the uneven reactor 210 is pressurized and stirred by the gas pressure. It works.

On the other hand, when the gas pressure rises in this way, the water level inside the reaction tank 200 is lowered, and conversely, the water level of the agitation tank 100 and the liquid ratio storage tank 300 is increased, but when the gas pressure is higher than a predetermined gas pressure (for example, 300 g / cm ² ). The gas discharge valve 220 provided on the upper surface of the reaction tank 200 is discharged so as to be lowered below a predetermined gas pressure (for example, 1.033 g / cm ² ). This can be achieved by implementing the gas discharge valve 220 using an automatic pressure valve.

On the other hand, it is possible to achieve the equilibrium of the water level as shown at the bottom of Figure 4 by the gas discharge.

After the gas is discharged, as the anaerobic digestion reaction is performed in the reaction tank 200, the gas pressure is gradually increased and the gas is discharged again. The expansion rate and emission frequency of the gas is proportional to the concentration and input of the organic waste, and the anaerobic digestion is further promoted by increasing the contact efficiency between the organic waste and the microorganism due to the change in the water level due to the gas discharge.

On the other hand, the view shown in the lower portion of FIG. 4 is a state in which the organic waste 1 is sucked from the stirring tank 100 while the water level inside the reaction tank 200 rises when the gas is discharged by the gas discharge valve 220. It is shown.

That is, when the water level rises due to the gas discharge, the water 2 and the organic waste 1 are simultaneously sucked from the stirring vessel 100 by the volume thereof. The sucked organic waste 1 is again subjected to a biochemical reaction in the reactor 200.

On the other hand, the methane gas purification device 230 is provided below the gas discharge valve 220. Biogas due to anaerobic decomposition is mainly composed of methane gas and carbon dioxide, but in addition to a small amount of toxic and corrosive emulsified gas and ammonia is discharged by the methane gas purification device 230 to remove it.

Adsorption of hydrogen emulsion is possible by passing through a filter filled with activated carbon and slaked lime. On the other hand, carbon dioxide can be removed by membrane filtration or zeolite adsorption.

Experimental results showed that heavy adsorption of 60 ~ 70% purity was produced when hydrogen sulfide was adsorbed, which corresponds to the level that can be used as fuel for heating or power generation. Meanwhile, carbon dioxide and other impurities must be removed in order to be used as a vehicle fuel and liquefied natural gas alternative fuel, and by removing carbon dioxide and ammonia, the methane content can be purified to more than 97%.

As a result, the gas discharge valve 220 may discharge high-purity methane gas from which emulsion gas is adsorbed and carbon dioxide is removed.

Meanwhile, as shown in FIG. 2, the gas discharge valve 220 is connected to the water separator 240 again, and the water separator 240 removes moisture from the discharged methane gas. Thereafter, the methane gas from which the water is removed is cooled to -80 ° C by the gas cooling filler 250. Meanwhile, the gas cooling filler 250 compresses the cooled methane gas by pressurizing and driving a cylinder, and then fills a separate container along a conduit. At this time, the gas cooling filler 250 is provided with a sensor for measuring the amount of methane gas and the concentration of methane gas filled in the container, so that the administrator can check how much filling is made. When filling is sufficient, the manager removes the filled container and connects the empty container to the gas cooled filler 250.

On the other hand, the liquid rain generating tank 300 is connected along the movement path to the right downward from the lower right of the reaction tank (200).

After the anaerobic digestion takes place sufficiently in the reactor 200 for a long time, water (fermentation liquid) 2 containing the inorganic substance and some organic substances is introduced into the liquid fertilization tank 300.

Residues, such as insoluble inorganic substances introduced into the liquid fertilizer generating tank 300 is precipitated and sinks, the precipitate 4 is deposited through the sediment discharge port 320 provided on the bottom of the liquid fertilizer generating tank 300. Dropping into the storage tank (400).

As shown in FIG. 4, the remaining fermentation broth 2 in which the precipitate 4 is dropped is left in the liquor generating tank 300, and the fermentation broth 2 is rich in minerals as a result of anaerobic digestion made in the reactor 200. It contains a small amount of scum (SCUM) component of the low specific gravity is going up. These scum components are decomposed and extinguished through a long residence period in the liquid fertilizer generating tank 300, and the high specific gravity shellfish, sand, etc. sink down. As such, water with high organic content is fermented and decomposed over a long period of time, and gradually becomes suitable as a liquid fertilizer (3).

Typically, organic waste having a BOD of 100,000 ppm to 200,000 ppm or more is added to the anaerobic digestion through the reactor 200, and lowers to 10,000 ppm. Thereafter, the BOD is lowered to several thousand ppm or less by moving to the liquid fertilizer generating tank 300 in a liquid state, and the organic waste, which is weak and strongly acidic in the stirring tank 100, passes through an acid fermentation and methane-balancing effected liquid fertilizer generating tank 300. ), It shows weak alkalinity.

On the other hand, the sediment storage tank 400 has a "b" shaped cross section as shown in Figures 2 and 4, and forms a depression in which the sediment discharge port 320 of the liquid rain generating tank 300 is recessed.

The depressions accumulated through the precipitate inlet 320 accumulate in the depression. As a result of the biochemical reaction in the reactor 200, since most organic matters are decomposed, only a small amount of residues remain, and only inorganic matters such as soil, sand, and shellfish remain.

The liquid fermentation 3 fermented over a long period of time in the liquid fertilization tank 300 is gradually moved downward according to its concentration, the remaining space except the depression of the sediment storage tank 400 is located so that the liquid fermentation fermentation (3) is the longest do.

The liquid inhaler 410 sucks out such a high concentration of liquid ratio 3 and draws it out to the outside. Preferably, the liquid ratio 3 extracts the liquid ratio 3 from the opposite point of the furthest distance from the depression on the sediment storage tank 400. This is because the point of depression is farthest from the organic waste inlet 110 as shown in Figs. 2 and 4 and thus can extract the liquid fertilization 3 from which the long-term fermentation has taken place.

As the liquid fertilizer 3 is drawn out, the liquid level of the liquid fertilizer generating tank 300 is lowered, and the manager checks the generation state and the level of the liquid fertilizer 3 through the inspection window 310 formed on the upper surface of the liquid fertilizer generating tank 300. If it is determined that the water level is low so that the organic waste or water into the organic waste inlet 100 of the stirring tank 100 to maintain the appropriate level.

On the other hand, by installing a separate CCTV (Closed Circuit Television), temperature sensor, water level sensor and the like in the predetermined position above and below the check window 310, it is possible to monitor the gas pressure, water level inside the liquid rain generating tank 300 from a remote location.

Typically, the organic wastes injected are anaerobic digested in the reactor 200 over a period of nearly one month. Usually, it is effective to maintain HRT for more than 30 days, but since the actual HRT becomes very long due to water evaporation by the heat of reaction, when the organic matter such as carbohydrate is fermented and decomposed, it hardly remains when it is moved to the liquid fertilization tank 300. . Therefore, when the multi-stage long-term residence type organic waste extinguishing resource treatment apparatus according to the present invention is manufactured in a large size of several meters each in width and length, residues do not greatly accumulate even after many years of use. It becomes possible.

Water is evaporated by fermentation heat, and carbohydrate components of organic waste are decomposed into methane gas and carbon dioxide gas during fermentation, and are discharged into gas, and trace amounts of carbohydrate, nitrogen, and phosphoric acid components are sucked into the liquid ratio (3). As mentioned above, the hydraulic residence time (HRT) becomes very long as a result of water evaporation, so most organic matters are completely degraded by microorganisms.

However, since some of the insoluble inorganic material mixed with the organic waste is precipitated and accumulated, a sediment discharge pump 420 may be provided, if necessary, to discharge the precipitate accumulated in the depression.

Meanwhile, in the above, the inlet 110 for the input of the organic waste and the inlet 120 for the microorganism are separately described, but may be implemented by combining them into one inlet as necessary.

On the other hand, with reference to Figure 5 will be described in detail the organic waste dissipation resource processing method according to the present invention. However, descriptions of matters overlapping with those described above will be omitted.

5 is a flowchart showing in time series the organic waste dissipation resource processing method according to the present invention.

First, water is filled in the stirring tank 100, the reaction tank 200, the liquid ratio generating tank 300, and the sediment storage tank 400 at predetermined water levels. The stirring tank 100, the reaction tank 200, the liquid ratio generating tank 300 and the precipitate storage tank 400 are connected as shown in FIG. 4 to achieve the same water level.

Thereafter, microorganisms containing strains for hydrolysis, acid fermentation and methane fermentation are added to pre-filled water and cultured (S110).

After the microorganism is cultured, the organic waste is input through the inlet 110 formed on the upper surface of the stirring tank 100 (S120).

After stirring the organic waste introduced into the stirring tank 100, the organic waste is hydrolyzed and acid fermented by the pre-cultured microorganisms (S130).

When the hydrolyzed and acid-fermented organic waste is moved to the reactor 200, anaerobic digestion is carried out by microorganisms pre-cultured in a sealed state (S140).

As a result of the anaerobic digestion in the reactor 200, a large amount of gas is generated, whereby the water level inside the reactor 200 is lowered (S151). On the other hand, when the gas pressure inside the reaction tank 200 reaches the threshold value, the gas is discharged (S152). As a result of the gas discharge, the water level inside the reaction tank 200 rises, and when the water level rises, the organic waste is sucked from the stirring tank 100 (S153).

In this case, as the organic waste is periodically input, the steps S120 to S153 are repeatedly performed.

On the other hand, the fermentation broth completed anaerobic digestion is moved to the liquid fertilizer generating tank 300, the liquid fertilizer generating tank 300 to decompose scum by staying in the fermentation broth for a long time (S160).

Inorganic matter contained in the fermentation broth is precipitated in the sediment storage tank (400) (S170).

Although the present invention has been described in detail with reference to some embodiments, the present invention is not limited to these embodiments and can be freely modified and practiced within the scope of the technical idea described in the claims.
