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

1, 6, and 9, the organic fertilizer and rye soil production system according to the present invention includes organic wastes divided into aged copper 100, agitated copper 120 and pack copper 140, 200, The aged copper 100 and the agitated copper 120 are each provided with an independent closed structure surrounded by a floor 1, a side wall 2 and a roof 3 as shown in Figs. 2 and 7, An air injection device 20, a malodor reduction device 110, and at least one fermenter 4, 5, 6 in the space.

Here, the air injecting apparatus has a structure in which the bottom 1 of the fermenter 4, 5, 6 is provided with a predetermined depth, a width, and a predetermined depth at regular intervals, as shown in FIGS. 1, 2, 6, A plurality of elongated grooves (10) crisscrossed and open at an upper portion in the longitudinal direction; A plurality of air supply pipes 24 arranged in the plurality of long grooves and exposed to the pores 26 formed on the side surface and penetrating the bottom of the fermenter to protrude out of the aged copper 100 or the stirring copper 120, ; An air distribution pipe (22) for distributing air by connecting the plurality of air supply pipes (24) from outside of the aged copper (100) or the stirring copper (120); And an air injector 21 connected to one end of the air distribution pipe 22 to supply compressed air.

The plurality of elongated grooves 10 may be formed in a trench shape when the cement is positive on the cement bottom 1 and are smaller than the lengths of the side walls of the side walls of the fermentation tanks 4 and 5 The depth of the groove 10 is 3.5 to 3/4 times larger than the outer diameter of the air supply pipe 24 and the width of the long groove 10 is 4/3 to 5/3 times larger than the outer diameter of the air supply pipe 24 .

By doing so, the leachate generated in the sediment can be stored in the grooves 10, and the leachate, which is supplied from the air injector 21 and impregnated into the grooves 10 and the air supply pipe 24, The fine sediments S such as rice hulls entered into the elongated grooves 10 are discharged from the elongated grooves 10 along with the leachate so as to be discharged to the lower portion of the sediment S .

The plurality of pores 26 may be irregularly formed around the entire surface of the air supply pipe 24 and may be formed to have a size of 1 to 3 mm so that the fine sediment S does not enter the pores 26.

When the depth of the grooves 10 is less than 3.5 / 3 times the outer diameter of the air supply pipe 24, there is a possibility that the air supply pipe 24 is damaged when the heavy equipment is passed. However, if it is 4/3 times, There is a problem that it becomes difficult to discharge the leached water and the fine sediments S which have entered the long groove 10 by the compressed air of the air injector 21 to the outside of the long groove 10 because a lot of fine sediments S are piled up inside the long groove 10.

If the width of the long groove 10 is less than 4/3 of the outer diameter of the air supply pipe 24, it is difficult to store sufficient leachate in the long groove 10 and the side wall of the long groove 10 and the air supply pipe 24, There is a problem that it is difficult to smoothly discharge the fine sediments S that have entered under the long grooves 10 to the compressed air through the pores 26 out of the long grooves 10.

Thus, when a plurality of grooves 10 are formed on the cement floor 1, a plurality of metal plates 12, which are bent in a 'C' shape during the course of cement growing, can be arranged and inserted at regular intervals. There is an advantage that the leakage of leachate through the long groove 10 as well as the problem of breakage of the long groove 10 due to the movement of heavy equipment can be solved.

2, it is preferable that the air distribution pipe 22 is connected at a predetermined height higher than the plurality of air supply pipes 24. By doing so, the leachate leaking into the air supply pipe 24 is discharged to the air distribution pipe 22).

Next, a malodor reduction device 110 is installed on each roof 3 of the fermentation copper 100, the stirring copper 120, and the packaging copper loading chamber 140 surrounding the fermentation tanks 4, 5 and 6, In this case, the leachate discharged from the fermentation tank is evaporated through the malodor reduction apparatus 110 and is discharged to the outside together with the malodorous gas, which can fundamentally solve the problem of polluting the environment caused by the discharge of leachate .

As described above, when the line mixer 70 according to the present invention is provided between the injection nozzle 54 and the exhaust device 60 in the gas discharge pipe 40, chlorine dioxide and odor gas (S-shaped rotation), and by repeating the division and mixing (stirring), the deodorizing effect can be enhanced by sufficiently stirring and reacting with each other while passing through the gas discharge pipe 40.

Also, since the line mixer 70 has a configuration in which a plurality of 180-degree twisted pretensioner plates are rotated at a predetermined angle (for example, 90 degrees) and connected in series, the equipment costs for odor reduction It also has the advantage of dramatically reducing operating costs.

2 or 5, the line mixer 70 is connected to the front end 42 of the gas discharge pipe 40 at a position adjacent to the injection nozzle 54, And the gas mixture discharged from the S-shaped rotation is continuously passed through the remaining gas discharge pipe 40. However, the gas mixture may be divided into two or more gas discharge pipes 40 and provided inside the gas discharge pipe 40. [

The exhaust device 60 is installed at the rear side 46 of the gas discharge pipe 40 and forces the odor gas in the closed spaces 100, 120 and 140 to be discharged to the outside through the gas discharge pipe 40. Therefore, An exhaust fan 62 provided inside the exhaust pipe 40, a motor for driving the exhaust fan 62, and a control unit 64.
