Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decomposition agent for treating garbage and a method for treating garbage using the decomposition agent.

[0002]

2. Description of the Related Art A large amount of garbage such as leftovers, marine and livestock waste, vegetable and vegetable waste, and food processing waste is discharged from facilities such as homes, restaurants, and food processing facilities. This decomposition treatment is a problem, and one of them is a method of decomposing these by predation of microorganisms. However, all the conventional microbial treatments are aerobic decomposition by aerobic bacteria. Therefore, garbage is stirred or garbage is forcibly fed (heated) to the garbage. Always keep in contact with air. However, even if this is done thoroughly, there are always places where the stirrer does not act or where air does not enter, and such places create an anaerobic environment.

[0003]

When garbage is under anaerobic conditions, aerobic bacteria cannot propagate, and emits off-flavors such as ammonia odor and offensive odors. For this reason, in the conventional garbage processing machine, it is essential to equip a deodorizing device, but at present, there is no deodorizing device for completely removing this bad smell. The present invention is to disintegrate garbage under anaerobic conditions by breeding anaerobic bacteria and anaerobic bacteria in harmony with the bacterial bed for garbage treatment.
It does not give off a bad smell.

[0004]

SUMMARY OF THE INVENTION Under the above-mentioned problems, the present invention provides a base material comprising rice bran as a main component, to which rice husk, bone phosphorus, fishmeal, and rapeseed oil cake are added, in which aerobic bacteria and anaerobic bacteria harmonize. Provided is a decomposition treatment agent for treating garbage, which is obtained by mixing a decomposition agent fermented by useful microorganisms propagated and a fermentation accelerating / moisture adjusting agent obtained by drying beans and grains. The decomposition agent constituting the present invention, rice bran as a main component, rice husk, bone phosphorus, fish meal,
Since a base material to which rapeseed oil cake is added is used, when aerobic bacteria and anaerobic bacteria are inoculated on the base material, each grows in harmony.
Therefore, when the garbage is eaten by these, the garbage is decomposed without emitting a bad odor even under anaerobic conditions. Further, at this time, the fermentation accelerating / moisture adjusting agent obtained by drying the beans and cereals absorbs (adjusts) the water content of the garbage to accelerate the decomposition.

Among the useful microorganisms mentioned above, there are those such as photosynthetic bacteria, lactic acid bacteria, yeast, gram-positive actinomycetes and enzymatic actinomycetes (these are classified into aerobic bacteria and anaerobic bacteria. Lactic acid bacteria belong to anaerobic bacteria, yeast,
Gram-positive actinomycetes belong to aerobic bacteria, which are already known). Each of them has the property of easily breeding under aerobic and anaerobic conditions. In addition, if the fermentation promoting and moisture controlling agent is obtained by carbonizing coffee grounds, the porous property exhibits a favorable aerobic condition and has a sufficient water absorbing power.

[0006]

Embodiments of the present invention will be described below. The decomposition treatment agent for treating garbage according to the present invention (hereinafter, referred to as
Decomposition agent) is a rice bran as a main component, rice hulls, bone phosphorus, fish meal, rapeseed oil lees base material fermented by useful microorganisms aerobic bacteria and anaerobic bacteria harmoniously propagated, Beans and grains (although coffee grains are commonly used)
Is mixed with a dried fermentation promoter / moisture regulator (hereinafter referred to as a promoter). In this case, each member constituting the base material is appropriately pulverized or the like so as to be easily used by microorganisms, and when the useful microorganisms described above are mixed and aged for about 45 days, the base material ferments.

FIG. 1 is an explanatory view showing an example of a garbage disposer for decomposing garbage using the decomposition agent.
This garbage disposer comprises a box-shaped decomposition tank 1 and a decomposition tank 1.
And a drive control unit 2 adjacent to. A stirrer 5 having a stirrer rod 4 protruding from a stirrer shaft 3 is provided in the decomposition tank 1. The stirrer shaft 3 is rotated by a motor (not shown) provided in the drive control unit 2. Can be Furthermore, decomposition tank 1
Is provided with a heater 6 and a pipe 8 for sending out hot air from an air outlet 7. Note that a heat source for the heater 6, a blower for sending air to the pipe 8, and the like are also provided in the drive control unit 2 (not shown). In addition, the decomposition tank 1 has an intake port 9 and an exhaust port 10 and an input port 11 for garbage.
And an outlet 12 are also formed.

When the above-mentioned decomposing agent and accelerator are put into the decomposition tank and stirred for 1 to 2 minutes with a stirrer, a decomposition treating agent is completed. In this case, the mixing ratio of the decomposer and the accelerator is in the range of 20 to 80% for the decomposer and 80 to 80% for the accelerator.
A range of 20% is suitable. The mixing ratio varies depending on the type of garbage (the more proteins such as meat and fish, the higher the ratio of the decomposing agent).
Suitably 40% decomposer and 60% accelerator. The garbage is decomposed by putting garbage on the decomposition agent, stirring the garbage with a stirrer, appropriately heating with a heater, and sending out hot air from an air blowing port. At this time, the decomposing agent has a direct role of aerobic bacteria and anaerobic bacteria contained therein acting on garbage to decompose, and the promoting agent has an indirect role of adjusting the moisture and accelerating the decomposition. Fulfill.

In this case, the amount of raw garbage to be charged is 1/8 to 1/12, preferably 1/10 of the decomposition treatment agent. If the amount is more than this, it takes a long time to decompose and the decomposition may be insufficient. The stirring in this case is
It is sufficient to rotate the stirring shaft at a low speed of about 1 to 20 rpm. Therefore, it is possible to expect a secondary effect that is required to suppress noise and reduce abrasion of the stirring rod. Further, the heating by the heater is sufficient if the temperature of the garbage is heated to about 40 ° C.
However, heating is sufficient until the garbage starts to ferment, and once fermented, fermentation heat is generated, so that heating is not required.

The garbage is decomposed as described above. In order to carry out this treatment efficiently, the processing temperature is 40 to 55 ° C., the humidity is 20 to 40%, and the
H is suitably maintained at 5 to 6. By the way, the garbage is not sufficiently decomposed by the decomposing agent while the garbage is being stirred. Therefore, the stirrer is operated intermittently to provide a pause. For example, if the stirrer is operated for 10 minutes, a cycle of stopping for a certain time is taken, and this is repeated. This pause time depends on the amount of water in the garbage, and if it exceeds 30%, it is 30 minutes.
A downtime of 1 hour is taken if it is 30% or less, and 2 hours is taken if it is 20% or less. In addition, of the 10-minute operation time, forward and reverse rotations such as forward rotation for 9 minutes and reverse rotation for 1 minute are performed to prevent garbage from being biased in the decomposition tank.

When the garbage is decomposed in this way, 2
Within 4 hours, the garbage is decomposed into water and carbon dioxide gas. During this time, aerobic bacteria and anaerobic bacteria grow in harmony and do not emit odor. Decomposition of the garbage into water and carbon dioxide means elimination of the garbage, and the content of the decomposition treatment agent after decomposition and the garbage-dissipated component hardly increases. However, since the decomposition processing agent absorbs the garbage processing component and the hardly decomposable substance adheres,
The apparent specific gravity increases (about twice in two months).

The following table shows the results of analysis of odor components after 24 hours in the case of processing the leftovers from the kitchen using the above-mentioned decomposition treatment agent. From this, it can be seen that all the odor components are less than the extent that they emit odor.

By the way, the period during which the above-mentioned decomposition treatment agent can continue its decomposition ability is finite, and generally about 3 months. This is because both aerobic bacteria and anaerobic bacteria are exhausted after this period, and their reproductive ability is reduced. Therefore, after this period, the decomposition treatment agent must be appropriately updated. For this update, the entire amount may be exchanged, or after an appropriate period (generally two months), about 2/3 may be replenished with about 1/3 remaining. In the latter case, fermentation is promoted by using the remaining decomposition treatment agent as a seed agent, so this is preferred.

The taken-out decomposition agent contains an effective fertilizer component in a well-balanced manner and can be recycled as compost. However, when a large amount of vegetable waste that has been sprayed with pesticides contains a large amount of heavy noble metals that are harmful to the soil, in this case, it is harmless if a secondary treatment is performed to complete fermentation together with cow dung, etc. Can be recycled into fertilizer.

[0015]

As described above, if garbage is treated with the decomposition treatment agent according to the present invention, the decomposition treatment agent can propagate aerobic bacteria and anaerobic bacteria in harmony and can be placed under anaerobic conditions. Garbage is also effectively decomposed and does not give off odor during this time. Therefore, the cost of the garbage processing machine can be reduced without the need for a deodorizing device or the like. In addition, since the used decomposition treatment agent becomes high-quality compost, it can be returned to farmland and recycled.
