Further, for the convenience of maintenance, a manhole is provided on the sewage storage area 2, and an air pipe is provided on the manhole, so that the sewage storage area 2 communicates with the first air source 3 through the air pipe. And, the sewage treatment zone 1 is provided with a manhole 10 in the third direction 93 of the elbow pipe 9, and the first air pipe 42 is provided in the manhole 10. It will be appreciated by those skilled in the art that the arrangement of the manhole 10 in the third direction 93 of the elbow 9 and the arrangement of the first air tube 42 in the manhole 10 facilitates replacement or repair of the air bag 41.
Furthermore, in the embodiment of the present specification, the sewage treatment area 1 is externally connected with a second air source 7; the sewage treatment area 1 is connected with a conduction pipe 8, the conduction pipe 8 comprises a transverse water inlet end 81 and a longitudinal water outlet end 82, the longitudinal water outlet end 82 is arranged in the sewage treatment area 1, and the opening direction of the longitudinal water outlet end 82 faces the bottom direction of the sewage treatment area 1. In the actual operation process, sewage in the unit area flows in through the transverse water inlet end 81 of the conduction pipe 8 and flows out to the sewage treatment area 1 from the longitudinal water outlet end 82, and the sewage treatment area 1 is externally connected with the second air source 7, so that in the pre-emptying process before rainfall occurs, compressed air can be filled into the sewage treatment area 1 through the second air source 7, the sewage in the sewage treatment area 1 is extruded to flow into the sewage discharge pipeline 5 through the on-off mechanism 4 to be discharged, and more volume space is reserved for the first sewage treatment 1 to contain the sewage. Of course, it will be understood by those skilled in the art that, in order to discharge more sewage in the sewage treatment area 1 in advance, the elevation of the water through holes 12 is preferably higher than the elevation of the pipe orifice of the longitudinal water outlet end 82 and/or the elevation of the pipe orifice of the elbow pipe 9 in the first communication direction 91.
It should be noted that, in this specification embodiment, sewage treatment region 1 and sewage regulation and storage region 2 can be 2 independent regions in the same cell body structure, also can correspond two cell body structures respectively, sewage treatment region 1 is a cell body structure promptly, sewage regulation and storage region 2 is a cell body structure, and when sewage treatment region 1 and sewage regulation and storage region 2 are two cell body structures, although can solve domestic sewage's regulation and storage problem, two sewage regulation and storage region separate designs, and the cost is higher, and area is also great, and many old cities do not have the local construction.
Therefore, as an optimal scheme, in the embodiment of the specification, the sewage treatment area 1 and the sewage storage area 2 are designed into 2 independent areas in the same tank body structure, so that the problem of domestic sewage storage and regulation is solved, the problem of occupied space is effectively solved, the cost is reduced, and in addition, all the structures are integrated in one tank body, so that the field installation and debugging are also very convenient. In addition, in order to further reduce the space of the sewage buffer tank and further reduce the occupied area, the septic part is adopted for pre-emptying before rainfall, so that the volume of the sewage buffer tank can be indirectly reduced.
As an application environment of the embodiment of the present specification, the sewage that needs to be regulated and stored may be regulated and stored by setting a regulation node according to the presence of rainfall, that is, the rainfall and the rainfall ending condition, for example:
when the rainfall is about to occur (the rainfall is not started), the on-off mechanism 4 can be controlled to be in an on state, meanwhile, the longitudinal water outlet end 82 of the on-off pipe 8 and the pipe orifice in the first communication direction 91 of the elbow pipe 9 are both submerged below the liquid level of the sewage, so that the whole sewage treatment area 1 is a sealed area, at the moment, the second air source 7 is used for filling compressed air into the sewage treatment area 1 to extrude the sewage in the sewage treatment area 1 to flow into the sewage discharge pipeline 5 through the on-off mechanism 4 for discharging, and because the height of the longitudinal water outlet end 82 in the sewage treatment area 1 is lower than the height of the pipe orifice in the first communication direction 91 of the elbow pipe 9, the extrusion process can be continued until the liquid level of the sewage in the sewage treatment area 1 just reaches the height of the pipe orifice in the first communication direction 91 of the elbow pipe 9, so as to realize the pre-emptying of the sewage treatment area 1, more volume space is made available for the sewage treatment zone 1 to accommodate sewage.
When raining, the second connection mechanism 4 is controlled to be in a connection state, so that after the domestic sewage in the unit area flows into the sewage treatment area 1 through the connection pipe 8, the liquid level of the domestic sewage in the sewage treatment area 1 continuously rises, and when the domestic sewage reaches the liquid level height of the first emptying port 61 of the emptying pipe 6, the domestic sewage automatically flows into the second storage area 2 through the first emptying port 61 under the action of self gravity to be stored.
After rainfall, the on-off mechanism 4 can be controlled to be in a conducting state, sewage in the sewage regulation and storage area 2 is sequentially discharged into the sewage treatment area 1 through the second emptying port 62 and the first emptying port 61 under the extrusion action of compressed air filled from the first air source 3, and is discharged into the sewage discharge pipeline 5 through the on-off mechanism 4 in the sewage treatment area 1, and finally is discharged into a downstream pipeline.
