Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a merger processing apparatus.
[0002]
[Prior art]
The purification process of manure is performed using a single treatment septic tank.
[0003]
FIG. 4 is a longitudinal sectional side view showing a single processing septic tank of a conventional separation contact aeration method. In the single treatment septic tank 1, manure is allowed to flow from the inlet 2 into the precipitation separation chamber 3 to perform solid-liquid separation and anaerobic treatment, and then transferred to the contact aeration chamber 4. In the contact aeration chamber 4, the treated water agitated is agitated by the bubbles of air diffused from the diffuser tube 7 and brought into contact with the contact material 8, and the nutrient substrate is oxidized and gradually removed. If the contact material 8 is continuously stirred, the biofilm accumulates thickly and closes. Therefore, the biofilm is peeled from the contact material 8 by periodically discharging air bubbles from the backwash tube 9. The treated water that has passed through the contact aeration chamber 4 is subjected to precipitation separation of solids in the sedimentation chamber 5, sterilized by transferring the supernatant liquid to the disinfection tank 6, and discharged from the outlet 10. In addition, 11 is a disinfectant container.
[0004]
[Problems to be solved by the invention]
In this single treatment septic tank, the type of sewage to be treated is limited to manure, and there is a problem that domestic wastewater such as kitchen wastewater, laundry wastewater, bathroom wastewater and bathtub wastewater cannot be treated.
[0005]
This problem can be solved by removing the existing single processing septic tank and installing a new merged processing septic tank, but not only the construction cost is high, but many single processing septic tanks are made of FRP. Therefore, a new problem also arises regarding the disposal of the single processing septic tank that has become unnecessary.
[0006]
Moreover, if the single treatment septic tank is buried without being dug up, there is a problem that the land cannot be effectively used although the problem of waste disposal does not occur.
[0007]
An object of the present invention is to propose a merger processing apparatus capable of effectively utilizing an existing single processing septic tank and realizing a merged processing septic tank.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
The single treatment septic tank that constitutes the merger treatment septic tank by connecting the merger treatment apparatus of the present invention is required to have at least an anaerobic treatment chamber or a sedimentation separation chamber, and a disinfection chamber. As described in the prior art, it is preferable to have an inlet and an outlet, and a precipitation separation chamber, a contact aeration chamber, a precipitation chamber, and a disinfection tank from the upstream side.
[0011]
The merger processing apparatus of this invention should just be provided with the filtration part which filters the biological reaction part for performing an aerobic process, and treated water at least.
[0012]
More specifically, the biological reaction section and the filtration section are described. As an example, a tank is filled with a carrier to form a carrier layer, and a diffuser pipe is provided at the bottom and inside of the carrier tank. The aerobic treatment is mainly performed by the carrier layer above the installed diffuser tube, and the filtration is mainly performed by the carrier layer below the diffuser tube installed inside the carrier layer. As another example, an upper and lower two-stage carrier layer partitioned by a water flow plate is formed, and an aeration tube is installed at the lower part of each carrier layer. The downstream carrier layer is configured as a filtration part.
[0013]
Since the carrier used in the biological reaction part can hold many microorganisms, it is made of synthetic resin such as a net-like cylindrical shape, a skeleton-like spherical shape, a square shape, a small cylindrical shape, a corrugated plate shape, a tube shape, or a fiber entangled shape. An inorganic body such as a molded body, a molded body made of a synthetic resin having closed cells or open cells, anthracite (anthracite), silica sand, and ceramic can be preferably used.

As the carrier (filter medium) used in the filtration part, a carrier using a carrier can be suitably used as in the biological reaction part. The carrier to be used may be the same form as that used in the biological reaction part or a different form. The air diffuser arranged at the bottom of the filtration unit does not discharge air bubbles in the normal state, and maintains an environment in which the carrier can be easily filtered while maintaining a stationary state. In order to peel the biofilm deposited thickly, air bubbles are discharged periodically and the carrier is stirred to peel the biofilm from the carrier. The peeled biofilm is preferably transferred to the anaerobic treatment chamber or the precipitation separation chamber of the single treatment septic tank by a washing drainage transfer pipe.
[0015]
The advection pipe transfers the treated water from the single treatment septic tank to the biological reaction section, and the treated water from the single treatment septic tank is treated water immediately before flowing into the disinfection chamber. Specifically, it is preferable to remove the treated water from the contact aeration chamber or settling chamber of the single treatment septic tank and transfer it to the biological reaction section. When a flow rate adjustment tank is provided upstream of the biological reaction unit, the treated water from the single treatment purification tank is once transferred to the flow rate adjustment tank and then transferred to the biological reaction unit.

[0040]
Furthermore, if the bathtub drainage is configured to be discharged directly out of the system without passing through the existing single treatment septic tank, sludge can be prevented from flowing out without increasing the capacity of the existing single treatment septic tank. At the same time, since the biological filtration treatment can be performed efficiently, the capacity of the biological filtration tank can be made compact, and the entire system can be miniaturized.
[0041]
Furthermore, when the flow control tank is provided in the merger processing apparatus, stable purification treatment can be performed. In particular, if the merger processing apparatus and the flow control tank are separated and connected by piping, the merger Construction cost can be reduced by installing the processing equipment on the ground.
[0042]
Moreover, since this invention can also newly establish a merged process septic tank using a new single process septic tank and a merger processing apparatus, the production efficiency of a single process septic tank and a merged process septic tank can be improved.
