BACKGROUND OF THE INVENTION
The present invention relates to a merger processing apparatus.
[0002]
[Prior art]
Conventionally, a single treatment septic tank has been used as a device for purifying manure. FIG. 5 is a schematic cross-sectional view showing a single processing septic tank of a separation contact aeration method. The manure flows from the inlet 2 into the precipitation separation chamber 3, undergoes solid-liquid separation and anaerobic treatment, and is transferred to the contact aeration chamber 4. In the contact aeration chamber 4, the advected water is agitated by the air bubbles diffused from the diffuser tube 7 and comes into contact with the contact material 8, whereby the nutrient substrate is gradually oxidized and removed. Since the biofilm accumulates thickly and closes when the contact material 8 is continuously stirred, the biofilm is peeled off by periodically discharging air bubbles from the backwash tube 9. The water that has passed through the contact aeration chamber 4 is subjected to precipitation separation of solids in the precipitation chamber 5, and then the separated supernatant is transferred to the disinfection chamber 6, sterilized, and then discharged from the outlet 10. Is done.

[Problems to be solved by the invention]
However, the single-treatment septic tank has a problem that the type of water to be treated is limited to manure, and it cannot treat household wastewater such as kitchen wastewater, laundry wastewater, bathroom wastewater, and bathtub wastewater. Such problems 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 is generated with respect to the disposal of the single processing septic tank that has become unnecessary. In addition, if the single treatment septic tank is buried without being dug up, a problem regarding disposal will not occur, but another problem will occur that the land cannot be used effectively.
[0004]
The present invention has been made in view of the problems as described above. By effectively utilizing the existing single-treatment septic tank, the problem of disposal of the single-treatment septic tank can be solved, and a new merged septic tank can be purchased. Another object of the present invention is to provide a merger treatment apparatus capable of treating domestic wastewater at a low cost.

DETAILED DESCRIPTION OF THE INVENTION
The single treatment septic tank for pipe connection of the merger treatment apparatus of the present invention is not particularly limited as long as it has at least an anaerobic treatment section or a sedimentation separation chamber, and a disinfection chamber. As described in the above, an apparatus having an inlet and an outlet and provided with a precipitation separation chamber, a contact aeration chamber, a precipitation chamber, and a disinfection chamber from the upstream side can be suitably used.
[0007]
The merger treatment apparatus used in the present invention is not particularly limited as long as it has at least a biological reaction part that performs aerobic treatment and a filtration part that filters wastewater. 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 diffusion tube is provided below and inside the carrier layer. The aerobic treatment is mainly performed in the carrier layer above the installed diffuser tube, and the filtration is mainly performed in the carrier layer below the diffuser tube installed inside the carrier layer. Further, as another example, a carrier layer which is formed upstream and bottom when partitioned by a water flow plate and an aeration pipe is installed below each carrier layer to allow water to flow through. Can be used as a biological reaction part, and a downstream carrier layer can be used as a filtration part.
[0008]
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 suitably used.
[0009]
As the carrier (filter medium) used in the filtration part, the same carrier as that used in the biological reaction part can be preferably used, but it may be different. The air diffuser placed at the bottom of the part to be filtered does not continuously discharge air bubbles in the normal state and maintains the environment in which the carrier is stationary and easy to filter. Since the biofilm is deposited thickly on the carrier, the carrier is stirred by periodically discharging air bubbles to peel off the biofilm from the carrier. The biofilm peeled off by washing the carrier is preferably transferred to the anaerobic treatment section or precipitation separation chamber of the single treatment septic tank by a washing drainage transfer pipe.
[0010]
The advection pipe used in the present invention transfers waste water from the single treatment septic tank to the biological reaction section, and the waste water from the single treatment septic tank is drained immediately before flowing into the disinfection chamber. Specifically, it is preferable to drain the waste water from the contact 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 waste water from the single treatment septic tank is once transferred to the flow rate adjustment tank and then transferred to the biological reaction unit.
[0011]
The washing drainage transfer pipe used in the present invention is for transferring the wastewater that has washed the filtration part of the combined treatment apparatus to the anaerobic treatment part or precipitation separation chamber of the single treatment septic tank, mainly from the carrier of the filtration part. Transport wastewater containing a lot of exfoliated biofilm.
[0012]
The return pipe used in the present invention returns the waste water on the downstream side of the filtration unit to the sterilization chamber of the single treatment septic tank, and the returned waste water is sterilized and discharged outside the system.
[0013]
The bathtub drainage pipe used in the present invention allows wastewater from the bathtub and bathroom to flow into the biological reaction part, and even if the wastewater from the bathtub and bathroom directly flows into the biological reaction part, it once flows into the flow rate adjustment tank. Then, it may be allowed to flow into the biological reaction part. Moreover, the waste_water | drain passing through bathtub drainage piping contains the waste_water | drain of a bathtub and a bathroom at least, You may flow the washing waste_water | drain with a low grade of dirt other than bathtub drainage.
[0014]
The bathtub drain pipe, Ru provided flow control valve. By doing in this way, the waste_water | drain of the bathtub and bathroom which generate | occur | produce in large quantities at once can be made to flow gradually into a biological reaction part, and a stable process can be performed now now. Also, instead of providing a flow control valve, a flow control tank is provided upstream of the biological reaction section so that the wastewater flowing into the merger treatment apparatus is temporarily stored in the flow control tank and then flows into the biological reaction section from there. It is also preferable to perform stable wastewater treatment.
