Description

BMP System for Organic Waste Landfill

The present invention relates to a Biological Mechanical Pretreatment (BMP) system for waste treatment, and more particularly, to provide a landfill digester in the form of a container so that organic waste is effectively decomposed, and the interior of the landfill digester is controlled by external air. By constructing to have an aerobic decomposition environment, it is possible to prevent the generation of harmful gases to the human body and the environment, and to quickly decompose high-concentration organic waste, which is the basic concept of BMP, to shorten the recycling cycle of the landfill digester, thereby reducing the number of landfills The present invention relates to a non-MPP system for efficient treatment of organic waste, which enables a large amount of organic waste to be decomposed into a digester.

In general, food waste is a representative high concentration organic waste among household waste.

The process of decomposing organic waste into inorganic substances is roughly classified into physicochemical decomposition (hydrolysis, dissolution, precipitation, adsorption) and biological decomposition (anaerobic, aerobic decomposition by microorganisms).

Biological degradation is the most commonly used, especially composting is the final target, and many researches and field applications have been conducted. Recently, pretreatment of organic waste as BMP (Biological Mechanical Pretreatment) has been of interest. .

Domestic household wastes totaled 46,438 tons / day as of 2000, and 27,676 (60%) tons of combustible (organic) waste and 11,434 tons of food waste accounted for 25% of the total household waste.

Among the household wastes, 80% of the household wastes except 19,167 tons of recycled land are disposed of in landfills, and food waste brought into landfills is estimated to be about 4,000 to 6,000 tons / day considering incineration and recycling.

The problem caused by landfilling such food waste directly into landfill is very serious. In other words, food waste has a high content of organic matter and energy, causing various environmental problems even after landfill disposal.In particular, high concentrations of organic matter embedded in landfills deteriorate leachate properties due to its decomposition products. There is a problem that causes an environmental burden due to landfill gas such as methane gas, which is a greenhouse material. In addition, because landfills are difficult to control as in the unit of a general environmental facility due to the characteristics of enlargement and diversification of structures according to the shape of the site, there is a problem that it is difficult to properly control organic waste in the landfill. will be.

In other words, direct landfilling of food waste, despite efforts to stabilize waste, has caused enormous environmental and economic losses, and the government has issued a ban on direct landfilling since 2005.

In order to solve the problems of the conventional landfill, the applicant of the present application has been registered in the patent 283209 'garbage landfill system and its processing method' configured as shown in FIG.

That is, referring to Figure 1, the applicant's patent 'garbage landfill system and its treatment method' includes a landfill digester 10, a plurality of leachate collection pipe 20, leachate discharge pipe 25 and leachate treatment and gas utilization portion It is configured by.

The buried fire extinguishing tank 10 is a sealed container shape, the lid 12 is provided in the inlet (10a) formed on the upper surface, the discharge door which is opened and closed along the guide groove (10c) in the opening (10b) formed on one wall surface. (14) is combined. Reference numeral 13 denotes a hook, and reference numeral 15 denotes an inclined surface.

A plurality of leachate collection pipes 20 are installed at the bottom of the landfill digester 10 to collect leachate generated from garbage embedded in the landfill digester 10, and the leachate installed through the landfill digester 10. The discharge pipe 25 is connected to one end of each of the leachate collection pipe 20 is configured to discharge the leachate collected by the leachate collection pipe 20 to the outside.

In addition, the leachate treatment and gas utilization unit, to separate the landfill gas from the leachate discharged through the leachate discharge pipe 25, the leachate is returned to the landfill digester 10 and the landfill gas is stored so that it can be used as energy It is configured to.

In this way, by disposing the organic waste in a landfill digester made in the form of a sealed container and then disposing the organic material, the landfill digester can not only prevent the environmental and economic loss due to the organic landfill being directly buried in the landfill. The reclamation of the landfill was achieved through repeated reuse of new landfills, which had the advantage of reducing the landfill space.

However, the waste landfill system and its treatment method are anaerobic decomposition methods without oxygen supply, which not only generate gas harmful to the human body and the environment, but also undergo a complicated chain reaction of several stages, and thus the decomposition process is not stable. The reaction rate is very slow, and accordingly, it takes a long time for the waste to stabilize, so that the recycling cycle of the landfill digester is too long to secure a large number of landfill digesters.

That is, in the case of anaerobic digestion of organic substances

C _a H _b O _c N _d S _e + ((4a-b-2c + 3d + 2e) / 4) H ₂ O →

((4a + b-2c-3d-2e) / 8) CH ₄ + ((4a-b + 2c + 3d + 2e) / 8) H ₂ O + dNH ₃ + eH ₂ S

to be.

Of these by-products, CH ₄ is valued as energy, but largely influenced by the economies of scale (Scale Merit), making it less valuable as a resource in small and medium sized landfills and having a significant impact on global warming and potential risks of explosion or fire. There was a problem.

In addition, as shown in the following scheme,

C ₆ H ₁₂ O ₆ → 2C ₂ H ₅ OH + 2CO ₂ + 2ATP

Anaerobic digestion of glucose metabolism undergoes a complex chain reaction of several stages, which leads to unstable decomposition and slow reaction rate, as well as very low production of ATP (Adenosine Tri Phosphate) per unit substrate. There are many problems with enzymes that are disadvantageous for organic matter treatment.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, by embedding the waste in the landfill digester made in the form of a container, the external air is supplied to the landfill digester to create an aerobic decomposition environment, It prevents the generation of harmful gases to the environment and the environment, and it is possible to shorten the recycling cycle of the landfill digester by quickly decomposing the high concentration organic waste which is the basic concept of BMP. Its main purpose is to provide a BMP system for efficient disposal of organic waste that can be decomposed and disposed of.

And gas discharge means configured to discharge gas generated from the waste in the landfill digester by the operation of the exhaust fan to the outside through the exhausting porous pipes and the gas discharge pipe.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of a non-MP system for the efficient treatment of organic waste according to the present invention will be described in detail.

Figure 2 is a block diagram showing an embodiment of a non-MPP system for the efficient treatment of organic waste according to the present invention, Figure 3 is a perspective view of the air inlet means and the gas discharge means of Figure 2, as shown, The invention comprises a landfill digester 50 made in a large container shape so as to store trash, an air inflow means and a gas discharge means.

The air inlet means, as a means for forming an aerobic decomposition environment in the landfill digester 50, the air inlet pipe 72 and a plurality of air inlet for introducing external air into the waste embedded in the landfill digester 50 It is configured to include a porous pipe for inflow (73).

That is, the air inlet pipe 72 is installed to penetrate one surface of the buried digestion tank 50, the plurality of inflow porous pipes 73 are branched from the air inlet pipe 72, respectively, buried digestion tank 50 By being installed to extend in the interior, the outside air is configured to be introduced into the landfill digester 50 through the air inlet pipe 72 and the inlet porous pipe 73, and thus the landfill digester 50 Waste air embedded in the outside air penetrates to create an aerobic decomposition environment.

The gas discharge means is a means for discharging the landfill gas generated from the waste in the landfill digester 50, and includes an exhaust fan 61, a gas discharge pipe 62, and a plurality of porous pipes 63 for discharge. It is configured by.

That is, the gas discharge pipe 62 is installed through the other surface of the landfill digester 50, and the plurality of exhaust porous pipes 63 are branched from one end of the gas discharge pipe 62, respectively, to the landfill digester ( 50 is installed to extend in the interior, the exhaust fan 61 is installed at the other end of the gas discharge pipe (62). Accordingly, when the exhaust fan 61 is operated, the landfill gas generated from the waste in the landfill digester 50 is discharged to the outside through the discharge porous pipes 63 and the gas discharge pipe 62. .

By the above-described configuration, after the waste is buried in the landfill digester 50 and the exhaust fan 61 is operated, the landfill gas generated from the landfill waste is discharged from the plurality of porous pipes 63 for discharge. And it is to be discharged to the outside through the gas discharge pipe 62, through this process, by forming a negative pressure inside the waste, the outside air to the air inlet pipe 72 and a plurality of inlet porous pipe 73 Through the landfill digestion tank 50 is introduced into the waste, thus, the aerobic decomposition environment is continuously maintained in the waste in the landfill digester 50.

This aerobic digestion takes place in the form of the following reaction.

C _a H _b O _c N _d + ((4a + b + 6c-2d) / 2) O ₂ → aCO ₂ + b / 2H ₂ O + NO ₃ ⁻

In other words, when organic matter is aerobic, no harmful gases such as CH ₄ , NH ₃ , H ₂ , H ₂ S, Mercaptanes, and aromatic hydrocarbons are generated, and the reaction process is simpler, so it reacts much faster than anaerobic decomposition. This is what happens.

In addition, aerobic metabolism of glucose, as shown in the following scheme,

C ₆ H ₁₂ O ₆ + 24 O ₂ → 6CO ₂ + 6H ₂ O + 38 ATP

High production rate of Adenosine Tri Phosphate (ATP) per unit substrate and low energy residue of the final product can be digested into a stable final treatment in nature.

On the other hand, the air inlet means, as shown, the air inlet pipe 72 is installed so as to extend along the inner bottom through the buried digestion tank 50, the inlet porous pipes 73 Branched from the air inlet pipe 72 may be installed vertically spaced apart from each other in the landfill digester (50).

In such a configuration, the outside air flows into the landfill digestion tank 50 to the upper layer portion inside the air inflow pipe 72 and penetrates into the waste through the inflow porous pipe 73, and at the same time, the air inflow pipe The waste leachate collected through the inflow porous pipes 73 is discharged to the outside to the lower part of the interior, thereby effectively achieving the effect of external air inflow and the leachate discharge. Instead of this configuration, the landfill digester 50 may be configured to provide a separate leachate discharge means to discharge the leachate generated from the waste inside the landfill digester 50.

In addition, in the case where the respective inflow porous pipes 73 are installed vertically in this way, the lower side of the height at which the waste is embedded in the landfill digester 50 from the branching point of the inflow porous pipes 73. Only the site consists of the perforated surface (73a), and the portion extending upward through the landfilled waste consists of a non-porous surface (73b) of which the upper end is blocked, so that all the outside flowing through each of the inflow porous pipe (73) It would be desirable to configure the air to penetrate into the waste.

In addition, by forming the upper and lower branch pipes (71a) (71b) by branching the outer end of the air inlet pipe (72) located outside the landfill digester (50), the outside of the upper branch pipe (71a) Air may be introduced into the landfill digester 50, and the leachate flowing through the lower portion of the air inlet pipe 72 may be discharged to the lower branch pipe 71b.

In addition, a leachate reservoir 81 is installed below the end of the lower branch pipe 71b, and a leachate spray tube 84 having a plurality of nozzles 84a is installed at an upper portion of the buried digester 50. A hose 83 is connected and installed between the leachate reservoir 81 and the leachate injection pipe 84, and a pump 82 is installed at one side of the hose 83 so that the leachate is operated when the pump 82 is operated. The leachate collected in the reservoir 81 may be configured to be returned to the waste inside the landfill digester 50 through the hose 83 and the leachate injection pipe 84. In this way, the means for returning the leachate generated from the waste back into the trash serves to suppress the external discharge of the leachate, which causes environmental pollution, and to keep the moisture necessary for garbage decomposition. Reference numeral 71c denotes a valve, and reference numeral 71b denotes a flexible pipe.

On the other hand, in the configuration according to the present invention, the required oxygen amount in the aerobic digestion reaction equation is obtained as follows.

If you first calculate the equivalent,

Waste: Oxygen (O ₂ ) = 180g: 768g

Here, the amount of landfill per unit cell is

3m ^W × 3m ^L × 4m ^H = 36㎥

Assuming apparent specific gravity of 0.6, 36㎥ × 0.6 = about 22 tons [garbage]

Assuming that the amount of organic matter in the waste to be treated is 60%

22 tons x 0.6 = about 13 tons [organic substance].

Where the required oxygen is

13 tons: oxygen demand = 180: 768,

Oxygen demand is 55 tons / digestion tank,

0.02243 m 3: 0.000032 ton = X: 55. The amount of oxygen is 38,500 m 3.

Therefore, the amount of air is 38,500 m 3 /0.21 = about 183,000 m 3,

When the oxygen utilization rate is 20%, 183,100㎥ / 0.2 = 915,000㎥.

A very large amount of air is required for complete digestion. However, complete digestion of organic substances is impossible and almost 60% of the total mineralization is considered to be technical limit. Therefore, the actual amount of air to be introduced is about 549,000㎥, which is 60% of 915,000㎥.

Therefore, if the residence time of BMP is 30 days and it is operated for 24 hours, the required air per unit digestion tank is

549,000 m 3 ÷ 30 ÷ 24 hours ÷ 60 minutes = approximately 13 m 3 / min.

The air supply amount may be achieved only by the amount of air introduced into the landfill digester 50 through the air inlet means by the negative pressure inside the landfill digester 50 formed by the operation of the exhaust fan 61. When the amount of inlet air is insufficient, an intake fan 70 may be installed in the upper branch pipe 71a, and the intake fan 70 may be configured to continuously supply forced air in an amount required to form an aerobic decomposition environment. will be.

On the other hand, the gas discharge means, as shown, one end of the gas discharge pipe 62 is installed to extend to the upper portion of the landfill digester 50, a plurality of exhaust porous pipes 63 are the gas discharge pipe 62 Branches are branched from one end and vertically installed in the landfill digester 50 so as to be spaced apart from each other, and each of the plurality of exhaust pipes 63 passes through the garbage surface from the branch point of the gas discharge pipe 62. It may be configured to have a perforated surface 63a up to a lower portion of the waste surface embedded in the landfill digester 50 and having a non-perforated surface 63b up to the portion.

In such a configuration, the negative pressure generated by the exhaust fan 61 is evenly transmitted to the inside of the garbage embedded in the landfill digester 50, so that the landfill gas generated from the garbage can be discharged quickly, and the air inflow means At the same time, the inflow of air is smoothly introduced, and the introduced air is uniformly infiltrated into the waste, thereby providing a better aerobic decomposition environment for the waste embedded in the landfill digester 50.

In addition, one side of the gas discharge pipe 62 is installed with a backwashing pipe 64, the backwashing pipe 64 is provided with a backwashing auxiliary fan 65, and a branching point of the backwashing pipe 64 A selection valve 66 for installing one of the two pipes 62 and 64 connected to the auxiliary fan 65 and the exhaust fan 61 to communicate with the exhaust porous pipes 63 is provided. Can be.

In this configuration, when the exhaust fan 61 is operated, normal operation is performed by adjusting the selector valve 66 so that the operation of the exhaust fan 61 is applied to the exhaust porous pipes 63. When the auxiliary fan 65 is operated, the auxiliary fan 65 is adjusted by adjusting the selector valve 66 so that the air pressure of the auxiliary fan 65 is applied to the exhaust pipes 63 for discharge. By applying the air pressure applied to the outer surface of each of the exhaust pipes 63 for the discharge is to operate to float the garbage blocking the hole, accordingly, when the exhaust fan 61 during the operation The sales of landfill gas through the mission (63) will be made smoothly. At this time, the operation of the exhaust fan 61 and the auxiliary fan 65, of course, should be made alternately, the auxiliary fan 65 will be enough to operate for several minutes every few hours.

In addition, it is possible to prevent foreign matters such as garbage embedded in the landfill digester 50 from being caught in the holes of each of the exhaust pipes 63 and the inflow pipes 73, thereby preventing the landfill gas and air flow. As shown in FIG. 4, it may be desirable to couple the air filters 68 and 78 to the outer surfaces of the respective porous tubes 63 and 73, respectively. Reference numerals 69 and 79 denote fastening bands for fixing the air filters 68 and 78.

On the other hand, the landfill digester 50 may be composed of a body portion and a lid portion. That is, the body portion is formed in a container shape having a waste inlet formed on the upper surface, and the lid portion is detachably coupled to the inlet, and after the filling of the waste in the body portion, the lid portion is coupled to the inlet of the body portion to the inside It may be configured to seal. In this configuration, the inside of the landfill digester 50 is tightly sealed to effectively prevent the outflow of landfill gas generated from garbage.

In the configuration according to the present invention, since the gas discharge means for forcibly sucking and discharging the landfill gas generated in the landfill digester 50 is provided, even when the top surface of the landfill digester 50 is opened It is discharged through the gas discharge means. Therefore, the configuration of the landfill digester 50 according to the present invention may be made of only the body portion without the lid portion.

Therefore, the stabilized waste can be easily discharged. At this time, the waste of the lower part is completely decomposed, and the upper part of the waste may be in progress and may perform a continuous processing function of discharging waste from the upper part and simultaneously discharging waste of the lower part. Since the configuration of the discharge door and the conveyor device is a conventional technology, those skilled in the art will be able to install and use in various shapes and structures.

In addition, in the configuration of the discharge door and the conveyor device as described above, by configuring the lower portion of the buried digestion tank 50 to the inclined surface becomes narrower toward the bottom, the conveyor having a narrower width than the width of the landfill digester 50 It will be desirable to configure so that all the waste inside the landfill digester 50 can be discharged.
