It is preferable to configure by filling. More preferably, the anaerobic filter material is irregularly packed. This is because in the anaerobic treatment method in which the air is not forcibly stirred, the treatment water is more easily diffused in the case of the irregular filling, and the room can be used more effectively.

The aeration tube installed in the contact aeration chamber may be removed, and if an aerobic filter medium (contact material) is installed in the contact aeration chamber, it may be removed, but it is preferably used as it is as an anaerobic filter medium I do. More preferably, it is replaced with an anaerobic filter medium of irregular filling. This is because, in many cases, the aerobic filter medium is regularly filled, and the anaerobic treatment method that does not forcibly agitate with air can be used effectively and irregularly, because the treated water is more likely to diffuse and the room can be used more effectively. Because you can.

The treated water comes in contact with the biofilm formed on the contact material provided in the contact aeration chamber by being stirred, and the aerobic microorganisms decompose organic substances and nitrify ammonia. If the stirring is continued, the biofilm generated on the surface of the contact material is thickly deposited and closed, so that the biofilm is periodically peeled off by air bubbles discharged from a backwash tube provided below the contact material. The detached biofilm is returned to the anaerobic treatment section of the single treatment septic tank.

放流するようにしても良い。[0014] The pipe connection between the single treatment septic tank and the merged treatment device connects the immediately before the disinfecting chamber of the single treatment septic tank with the inlet of the merged treatment device, and connects with the outlet of the merged treatment device. This is performed by connecting the disinfection chamber of the single treatment septic tank. At the inlet of the single treatment septic tank, there is provided a pipe through which human waste, kitchen wastewater, washing wastewater and the like other than the bathtub wastewater flow. This is because the bath tub drainage is less contaminated and larger in volume than other household wastewater, and may be discharged directly out of the system without passing through the single treatment septic tank and the combined treatment equipment. is there. More preferably, a bathtub drainage pipe for bathtub drainage is separately provided, and only the bathtub drainage is directly flowed into the combined treatment device for treatment, or is passed through a disinfection room of a single treatment septic tank to be disinfected and sterilized before being removed from the system. You may make it discharge to.

の時間を少しでも短くするためである。By the way, washing wastewater has a larger amount of dirt than bathtub wastewater, but less than kitchen wastewater. Therefore,
It is preferable that the washing drainage also flows into the bathtub drainage pipe for the bathtub drainage and does not pass through the existing single treatment septic tank like the bathtub drainage, but instead flows into the combined treatment device for treatment, or is sterilized and discharged. Is preferred. However, when the washing drainage flows into the bathtub drainage pipe, the flow control valve is installed upstream of the position where the washing drainage flows into the bathtub drainage pipe so that the washing drainage does not pass through the flow control valve. Is preferred. The reason for this is that the amount of water in the washing drainage is small enough to adjust the flow rate, the drainage is performed quickly, and the time for washing having a plurality of steps such as washing, rinsing, and dehydrating is shortened as much as possible.
