Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a livestock excrement treating apparatus for decomposing feces of livestock such as cows, lids and chickens by the action of microorganisms, and a livestock excrement treating method using the treatment apparatus.

[0002]

2. Description of the Related Art Decomposition of livestock excrement by the action of microorganisms has been performed for a long time. In this type of treatment, it is usual that feces and urine are separated (solid-liquid separation), and solid is decomposed into solid and liquid is decomposed into liquid separately. In this case, both components are pretreated so that they are easily utilized by microorganisms and decomposed by the action of microorganisms. still,
When these excrements are decomposed by anaerobic bacteria, they decompose and generate a bad odor, etc. Therefore, decomposition by aerobic bacteria is suitable.

[0003]

Therefore, in the conventional processing apparatus of this kind, what effective pretreatment or how to maintain the aerobic environment is the key to success or failure. Was there. The present invention is intended to solve such a problem and to enhance the growth environment of aerobic microorganisms and enhance their decomposing power when the solid-liquid separated liquid component is decomposed by the action of microorganisms.

[0004]

Under the above problems, the present invention provides a livestock excrement treating apparatus for solid-liquid separating livestock excrement according to claim 1 and decomposing the same by the action of microorganisms. A plurality of decomposition tanks for decomposing treatment are provided, a first aeration tank to which the bioactive liquid containing minerals is added is provided on the upstream side of the decomposition tank, and a finishing tank in which a polished oyster shell is immersed is provided on the downstream side. The present invention provides an apparatus for treating livestock manure characterized by the above.

The present invention also provides a livestock excrement treating method using a livestock excrement treating apparatus for solid-liquid separating livestock excrement and decomposing it by the action of microorganisms.
A plurality of decomposition tanks for decomposing liquid components are provided, and a bioactive liquid containing minerals is added to the first aeration tank on the upstream side of the decomposition tank to activate microbial action, and the surface is added to the finishing tank on the downstream side. Provided is a method for treating livestock excrement by a livestock excrement treating apparatus, which comprises immersing a polished oyster shell in a microbial growth bed.

When a biologically active liquid containing minerals is added in the aeration process of the liquid content, the mineral content suppresses the activity of anaerobic bacteria and makes the liquid content less prone to decay, and also propagates as nutrients for aerobic bacteria. Encourage. Further, it is said that this mineral component absorbs wave energy in the air to activate the liquid component. Furthermore, when the oyster shell with a polished surface is immersed in a finishing tank constituting the downstream side of the decomposition tank, the micropores formed in the oyster shell serve as a perfect growth bed for microorganisms, promoting their growth and promoting decomposition.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a layout and flow diagram of a decomposition treatment apparatus showing an example of the present invention. Manure discharged from a livestock barn is temporarily stored by adding water to an underground tank 1 or the like. This is pumped up by the pump 2 and sent to the solid-liquid separator 3, where it is separated into a solid content 4 and a liquid content 5. Of these, the solid content 4 is made into compost, which is sent to the compost house 7 by the conveyor 6 or the like and appropriately turned by the shovel 8 or the like to ferment it.
The fermented compost 9 is transported to a desired farm by a truck 10 or the like, or stored in the stockyard 11.

On the other hand, the liquid content 5 is once stored in the storage tank 1.
2 and collect them in the underwater mixer 13 with appropriate stirring. This is sent to the decomposition tank 15 by the pump 14 and decomposed here. The decomposition tank 15 in this example is
From the upstream side, the first aeration tank 16, the second aeration tank 17, the precipitation tank 1
8 and finishing tank 19. Decomposition by the first and second aeration tanks 16 and 17 is carried out by sending air through the blower 20 to bring the liquid component 5 into contact with air and performing decomposition by the action of aerobic bacteria.

One of the features of the present invention is that the first decomposition tank 15 is used.
The bioactive liquid 2 containing minerals in the first aeration tank 16
Is to add 1. By adding this mineral content,
The activity of the anaerobic bacteria is suppressed to make the liquid content 5 less likely to rot, and this serves as a nutrient for the aerobic bacteria to promote reproduction. Furthermore, it is said that this mineral component absorbs wave energy in the air to activate the liquid component 5.

The liquid component 5 decomposed in the first aeration tank 16 is
It is moved to the second aeration tank 17 and is moved to the precipitation tank 18 while continuing to be decomposed here. The transfer may be natural transfer by overflow or downflow, or forced transfer by pressurizing with a pump or the like. The liquid content 5 transferred to the settling tank 18 is
Since the sludge component collects at the bottom, it is returned to the first aeration tank 16 by the pump 22, and the decomposition is repeated.

The liquid component 5 in the settling tank 18 is transferred to a finishing tank 19 where it is finished. This finishing process also
The blower 20 sends air into the finishing tank 19 (23 is a filter) for aerobic decomposition by aerobic bacteria. In the present invention, the oyster shell 24 is immersed in the finishing tank 19 to accelerate the decomposition. Of.

FIG. 2 is a perspective view of the oyster shell 24. It is essential that the surface (front and back) of the oyster shell 24 used here is polished to completely remove seaweed and mud attached to the surface. Is. Many micropores are formed on the surface of the oyster shell 24, and this serves as a growth bed for microorganisms. However, if seaweed or mud remains, the pores will be blocked and the growth bed effect will not be sufficiently exerted. Because.

FIG. 3 is an explanatory view showing how the oyster shells 24 are immersed, but the above oyster shells 24 may be housed in a suitable net bag 25 and hung in the finishing tank 19. The amount of the oyster shells 24 used at this time may be arbitrary, but the larger the number, the more the growth bed and the more active the microorganisms. In addition, oyster shell 2
4 is mainly composed of calcium carbonate, which is dissolved by the activity of microorganisms and its amount is reduced, so that it is sufficient to supplement the reduced amount appropriately.

When such decomposition is continued, the liquid content 5 is finally decomposed into detoxified carbon dioxide gas and water. Therefore, the water content is pumped up by the pump 26 and returned to farmland or the like. do it. Further, it may be returned to the first underground tank 1 and used as a filler or substitute for water to be added.

[0015]

As described above, according to the present invention, the aerobic decomposition is completed more completely in a short time by adding the bioactive water and using the oyster shell when treating the liquid content of livestock excrement. Therefore, it is not necessary to make the equipment large, and the cost can be reduced and the space can be saved.
