Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a combined treatment apparatus for simultaneously treating manure and household wastewater such as kitchen wastewater, laundry wastewater, wash surface, and bathroom wastewater.
[0002]
[Prior art]
Conventionally, a single treatment septic tank has been used as a device for purifying manure.
FIG. 9 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. If the contact material 8 continues stirring, the biofilm accumulates thickly and closes. Therefore, 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 solid separation in the sedimentation chamber 5, and then the separated supernatant is transferred to the disinfection chamber 6, sterilized, and then from the outlet 10. It is released.

[0006]
DETAILED DESCRIPTION OF THE INVENTION
The merger treatment apparatus of the present invention has a configuration in which a second treatment purification device is connected to a single treatment purification device (tank) by piping.
The single treatment septic tank to which the second treatment purification device is connected is not particularly limited as long as it has an anaerobic treatment unit and / or an aerobic treatment unit and a disinfection chamber. Specifically, as described in the prior art, 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 is preferably used. be able to.
[0007]
The second treatment purification apparatus used in the present invention is not particularly limited as long as it has at least a contact aeration tank and a precipitation tank for performing aerobic treatment. Preferably, the contact aeration tank is aerobic. A filter medium (contact material) is used, and a diffuser pipe and a backwash pipe are arranged at the bottom.
[0008]
The contact aeration tank of the second treatment purification apparatus is a part that performs aerobic treatment by stirring the treated water transferred from the single treatment purification tank with air bubbles discharged from an air diffuser arranged at the bottom. The stirred treated water comes into contact with the biofilm formed on the contact material provided in the contact aeration tank, and the organic matter is decomposed and ammonia is nitrified by aerobic microorganisms. If stirring with air bubbles discharged from the air diffuser is continued, the biofilm formed on the surface of the contact material will be deposited thickly and clogged, so the air bubbles discharged from the backwash tube provided at the bottom of the contact material will periodically The biofilm is peeled off. The peeled biofilm is returned to the anaerobic treatment section of the single treatment septic tank or released out of the system.
[0009]
The advection pipe used in the present invention transfers waste water from the single treatment purification tank to the contact aeration tank of the second treatment purification apparatus, and includes a settling chamber or a contact release chamber of the single treatment purification apparatus, It connects with the inflow port of a process purification apparatus. That is, the waste water flowing into the second treatment purification device from the single treatment purification tank is the waste water immediately before flowing into the disinfection chamber of the single treatment purification device. Specifically, it is preferable to drain the waste water from the contact chamber or settling chamber of the single processing septic tank and transfer it to the contact aeration tank of the second processing and purification device.
[0010]
The return pipe used in the present invention is disposed by connecting the sedimentation tank of the second treatment purification apparatus and the disinfection chamber of the single treatment purification tank. The waste water from the sedimentation tank of the second treatment purification device is returned to the disinfection chamber of the single treatment purification tank, and the returned waste water is sterilized and discharged from the outlet to the outside of the system. .
[0011]
When the cleaning wastewater transfer pipe is provided in the combined treatment apparatus of the present invention, the cleaning wastewater transfer pipe is disposed by connecting the contact aeration tank of the second treatment purification device and the immediately after the inlet of the single treatment purification tank, The waste water from which the contact material in the second treatment purification apparatus is washed is transferred immediately after the inlet of the single treatment purification tank. That is, the washing drainage transfer pipe transfers wastewater containing a large amount of biofilm separated from the contact material of the contact aeration tank.
In addition, the waste water after washing the contact tank may be directly discharged out of the system, and in this case, no washing waste water transfer pipe is provided.
[0012]
In the present invention, a pipe for conveying manure other than bathroom wastewater, kitchen wastewater, laundry wastewater and the like is connected to the inlet of the single treatment septic tank. The reason why the bathroom wastewater is not connected to the inlet of the single treatment septic tank is that the bathroom wastewater is less contaminated and more in volume than other domestic wastewater, so the single treatment septic tank and the second treatment purification device are This is because it may be discharged directly outside the system without passing through.
[0013]
Moreover, in this invention, it is good also as a structure which connects the bathroom drainage piping for bathroom drainage separately from other drainage piping, and flows directly into a 2nd process purification apparatus. Further, as a configuration in which the bathroom drain pipe is directly flowed into the sterilization chamber of the single treatment septic tank, it may be sterilized and then discharged out of the system. Furthermore, by providing a dedicated pipe for washing drainage and connecting it in the middle of the bathroom drainage pipe, the same treatment as the bathroom drainage may be performed and discharged outside the system. This is because laundry wastewater is less contaminated and larger than kitchen wastewater and manure.
[0014]
In the present invention, it is preferable to provide a flow rate adjustment valve in the bathroom drain pipe. The flow control valve adjusts the amount of drainage transported through the bathroom drainage pipe, and reduces the fluctuation in the amount of bathroom drainage flowing into the second treatment purification device, thereby improving the efficiency of the contact aeration tank. Achievement of air treatment and efficient sterilization of water that has flowed into the disinfection tank are performed by reducing fluctuations in the amount of water flowing when passing through the disinfection chamber of the single treatment septic tank.
However, when the laundry drainage pipe is connected, the flow rate adjusting valve is preferably provided upstream of the connection part of the laundry drainage pipe. This is because the waste water is discharged at every washing, rinsing, and dehydration process of the washing machine, so that the waste water is quickly flowed into the contact aeration tank or the disinfection chamber at any time without using the flow control valve.
[0015]
In the merger treatment apparatus of the present invention, a flow rate adjustment tank is provided upstream of the contact aeration tank of the second treatment purification apparatus, and the wastewater flowing into the second treatment purification apparatus is once stored in the flow adjustment tank, from there Stable wastewater treatment is achieved by flowing into the contact aeration tank.
