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. 6 is a schematic cross-sectional view showing a single processing septic tank using 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 separated from the solid in the sedimentation 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 a tank in which an anaerobic treatment is performed, and specifically, as described in the prior art. It is possible to suitably use 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.
[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 filter medium layer is formed by filling a tank with a filter medium, and a diffuser pipe is provided below and inside the filter medium layer, and inside the filter medium layer. The aerobic treatment is mainly performed in the upper filter medium layer from the installed diffuser pipe, and the filtration is mainly performed in the filter medium layer below the diffuser pipe installed in the filter medium layer. Further, as another example, a filter medium layer formed by two upper and lower stages partitioned by a water flow plate and a diffuser pipe installed at the lower part of each filter medium layer, the filter medium layer on the upstream side when water is passed through Can be used as the biological reaction part, and the filter medium layer on the downstream side can be used as the filtration part.
[0008]
Since the filter medium 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 filter medium used in the filtration part, the same filter medium 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 filter medium remains stationary and easy to filter. Since the biofilm accumulates thickly on the filter medium, the air filter is periodically discharged to stir the filter medium, and the biofilm is peeled off from the filter medium. The peeled biofilm is preferably transferred to the anaerobic treatment section of the single treatment septic tank through 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 unit, and connects one end to the outlet of the single treatment septic tank and connects the other end to the combined treatment apparatus. The connection location on the merger processing apparatus side may be directly transferred to the biological reaction unit, or may be transferred once to the flow rate adjusting tank and then transferred to the biological reaction unit. Moreover, when the disinfection tank is provided in the upstream of the outflow port of the single processing septic tank, the disinfectant in the disinfection tank is extracted.
[0011]
The washing drainage transfer pipe used in the present invention is for transferring wastewater that has been washed by the filtration unit of the combined treatment apparatus to the anaerobic treatment unit of the single treatment septic tank. Transfer the membrane.
[0012]
The bathtub drainage pipe used in the present invention is a pipe that allows drainage from the bathtub and bathroom to flow into the disinfection tank attached to the combined treatment apparatus. The drainage generated in the bathtub and bathroom is less contaminated with water and can be discharged only by sterilization. Such treatment is performed on waste water with less dirt, and washing waste water and the like can be used in addition to waste water from a bathtub and a bathroom.
