BACKGROUND OF THE INVENTION
The present invention relates to a merger processing apparatus that enables purification treatment of human wastewater and household wastewater such as kitchen wastewater, laundry wastewater, wash surface / bathroom wastewater and the like.
[0002]
[Prior art]
Conventionally, a single treatment septic tank has been used as a device for purifying manure. FIG. 3 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 40. It becomes the composition which is done. In addition, although the contact aeration method was shown as an aerobic treatment method, there is also an aeration method in which air bubbles are diffused and only air agitation is used.

(Example)
Embodiments of the present invention will be described below with reference to the drawings.
1 and 2 are explanatory views of the configuration of a merger processing apparatus 100 according to an embodiment of the present invention. FIG. 1 is a schematic side sectional view and FIG. 2 is a schematic plan view.
[0012]
The merger processing apparatus 100 is configured by connecting a first processing tank 10, a second processing tank 20, and a third processing tank (existing single processing septic tank) 30 by piping. Here, the 1st processing tank 10 and the 2nd processing tank 20 perform the pre-process of the waste_water | drain which flows into the single process purification tank 30. FIG.
The first treatment tank 10 connects the inlet 11 to the pipe 51. The outflow port 13 is connected to the inflow port 21 of the second treatment tank 20 through the first connection pipe 55. The 1st processing tank 10 performs anaerobic processing.
The second treatment tank 20 is provided with a pump 25. And the inflow port 21 and the outflow port 23 of sewage are provided. Further, the second treatment tank 20 is provided with an air diffuser 24 and aerobic treatment is performed in the second treatment tank 20 by performing preliminary aeration, so that a third treatment tank (existing) is provided. The single processing septic tank) is reduced.
[0013]
In addition, a bathroom drain pipe 53 that transports the bathroom drain b is connected to the first connection pipe 55 that connects the first treatment tank 10 and the second treatment tank 20.
The waste water pumped up by the pump 25 flows into the third treatment tank (existing single treatment purification tank) 30 from the second connection pipe 59 connected to the outlet 23 of the second treatment tank.
[0014]
The single processing septic tank 30 uses the existing one. The internal structure is provided with, for example, an inlet 31, a sediment separation chamber 32, a contact aeration chamber 33, a sedimentation chamber 34, a disinfection chamber 35, and an outlet 36 from the upstream side.
[0015]
Next, the flow of water will be described.
The manure, kitchen wastewater, laundry wastewater, and bathroom wastewater a discharged from the home flows into the first treatment tank 10 from the pipe 51. Therefore, it is anaerobically treated and flows into the second treatment tank 20 through the first connection pipe 55. On the other hand, the bathroom drain b flows into the first connection pipe 55 from the bathroom drain pipe 53 and into the second treatment tank 20.
[0016]
Wastewater a such as manure, kitchen wastewater, laundry wastewater, wash water drainage, and bathroom wastewater b flowing into the second treatment tank 20 is pumped up by the pump 25 and transferred from the second connection pipe 59 into the single treatment septic tank 30. The
In the second treatment tank 20, the amount of outflow to the single treatment purification tank 30 can be adjusted by the pump 25.
[0017]
The wastewater that flows into the precipitation separation chamber 32 from the inlet 31 of the single treatment septic tank 30 after the inflow amount is adjusted is subjected to solid-liquid separation and anaerobic treatment in the precipitation separation chamber 32. Then, the nutrient substrate is oxidized and removed in the contact aeration chamber 33.
