As another implementation manner of the first embodiment of this specification, please refer to fig. 3, in which the sewage treatment apparatus further includes; the conducting pipe 50 is arranged in the first processing area 20, and the conducting pipe 50 specifically comprises a first conducting opening 501 and a second conducting opening 502.

Specifically, in this embodiment, the second switch 122 disposed at the gravity port 160 can be eliminated because the gravity port 160 is disposed at the bottom of the first treatment region or the second treatment region before the conducting pipe 50 is not disposed, so that the water can flow between the first treatment region and the second treatment region, and when the water in the first treatment region or the second treatment region is sewage, the residue or other contaminants with high concentration in the sewage can easily settle at the bottom, which can easily cause the blockage of the gravity port 160, and even if the gravity port 160 is not blocked, when the water in the second treatment region enters the first treatment region from the gravity port 160 under the action of air pressure, the bottom of the first treatment region can be "stirred", which is not favorable for the biochemical and discharge of the contaminants in the water in the first treatment region.

Therefore, in this embodiment, the conduction pipe 50 is additionally provided, and the conduction pipe 50 is communicated with the gravity port 160 through the second conduction port 502, and the pipe orifice level of the first conduction port 501 is higher than the bottom level of the sewage drain 170. Therefore, when water needs to be stored, the first valve 406 is closed and the second valve 407 is opened, and the first switch 121 at the sewage outlet 170 is closed, so that along with the continuous rise of the liquid level of the water in the first treatment area, when the water just reaches the pipe orifice elevation of the first conduction port 501, the water in the first treatment area flows into the second treatment area through the conduction pipe 50 under the action of gravity. The pipe orifice of the first conduction port 501 is higher than the bottom elevation of the sewage outlet 170, so that when water in the first treatment area is normally discharged, the conduction pipe 50 does not need to be additionally controlled, the liquid level of the water in the first treatment area is directly discharged from the sewage discharge pipeline 30 when reaching the height of the sewage outlet 170, and therefore the technical defects that residues or other pollutants with higher concentration in the sewage in the first treatment area or the second treatment area are easy to settle at the bottom to cause the blockage of the gravity port 160, or even if the gravity port 160 does not cause certain stirring to the bottom of the first treatment area under the blockage condition, the biochemical treatment and the discharge of the pollutants in the water in the first treatment area are not facilitated are effectively overcome; when the water in the second treatment area needs to be discharged, the first valve 406 is opened and the second valve 407 is closed, the air source 120 charges compressed air into the second treatment area 40 to form air pressure in the second treatment area 40, and further, the water in the second treatment area 40 is extruded to flow into the first treatment area through the conduction pipe 50, so that the technical effect of regulating and storing the sewage when the sewage is not required to be discharged is achieved, and the device has the characteristics of simple structure, convenience in operation and wide applicability.

As another embodiment of the first embodiment of the present specification, please refer to fig. 4, which corresponds to the embodiment shown in fig. 3, except that a second switch 122 is added at the position of the gravity port 160, at this time, since the second switch 122 can control the flow of the conducting tube 50, the elevation of the tube orifice of the first conducting port 501 may not be limited in this embodiment, and may be any elevation higher than the top elevation of the gravity port 160. Similarly, when water storage is needed, the first valve 406 is closed and the second valve 407 is opened, the first switch 121 at the sewage outlet 170 is closed, the second switch 122 is opened, and as the liquid level of the water in the first treatment area rises continuously, the water in the first treatment area flows into the second treatment area through the conduction pipe 50 under the action of gravity when the water just reaches the pipe orifice level of the first conduction port 501. And because the pipe orifice elevation of first conduction mouth 501 is higher than the bottom elevation of drain 170, when normally carrying out the emission of first treatment zone internal water, also need not carry out additional control to conduction pipe 50 like this, the liquid level of the water in the first treatment zone directly is discharged by sewage pipes 30 when reaching the height of drain 170, it settles easily at the bottom to have solved effectively to this residue or other higher pollutants of concentration in the sewage in first treatment zone or second treatment zone, and lead to the jam of gravity mouth 160, or even gravity mouth 160 causes certain "stirring" to the bottom of first treatment zone under the circumstances of not blockking up, be unfavorable for the technical defect of the biochemistry of aquatic pollutant in the first treatment zone and emission. When the water in the second treatment area needs to be discharged, the first valve 406 is opened and the second valve 407 is closed, the air source 120 charges compressed air into the second treatment area 40 to form air pressure in the second treatment area 40, and further, the water in the second treatment area 40 is extruded to flow into the first treatment area through the conduction pipe 50, so that the technical effect of regulating and storing the sewage when the sewage is not required to be discharged is achieved, and the device has the characteristics of simple structure, convenience in operation and wide applicability.

Wherein the conduction pipe 50 is communicated with the first processing area 20 through the first conduction opening 501; the pipe orifice of the first conduction port 501 is higher than the bottom elevation of the sewage draining exit 170; a second via 502 is located at the bottom of the second processing region 40. It should be noted that, in the embodiment shown in fig. 5-7, the first switch 121 may be an air bag which can be inflated and exhausted through the air pipe 1211, the sewage outlet 170 may be a bent inlet, that is, one end of the sewage conduit 30 connected to the first processing region is bent, so that the opening of the sewage outlet 170 faces downward, and an elastic region for elastically expanding the air bag is disposed in the inner space of the sewage outlet 170, which may be understood as when the air bag is filled with air, the air bag expands to fill the entire elastic region, at this time, the "conducting function" of the sewage outlet 170 is turned off, and when the air bag exhausts air, the elastic region starts conducting, at this time, the "conducting function" of the sewage outlet 170 is turned on. Similarly, when water storage is needed, the first valve 406 is closed and the second valve 407 is opened, and the first switch 121 at the sewage outlet 170 is closed, so that as the liquid level of the water in the first treatment area rises, the water in the first treatment area flows into the second treatment area through the conduction pipe 50 under the action of gravity when the water just reaches the pipe orifice level of the first conduction port 501. Since the pipe orifice of the first conduction port 501 is higher than the bottom elevation of the sewage outlet 170, the conduction pipe 50 does not need to be additionally controlled when water in the first treatment area is normally discharged, and the liquid level of the water in the first treatment area is directly discharged from the sewage discharge pipeline 30 when the liquid level reaches the height of the sewage outlet 170; when the water in the second treatment area needs to be discharged, the first valve 406 is opened and the second valve 407 is closed, the air source 120 charges compressed air into the second treatment area 40 to form air pressure in the second treatment area 40, and further, the water in the second treatment area 40 is extruded to flow into the first treatment area through the conduction pipe 50, so that the technical effect of regulating and storing the sewage when the sewage is not required to be discharged is achieved, and the device has the characteristics of simple structure, convenience in operation and wide applicability.

For the conduction pipe 50 in any one of the embodiments of fig. 3, fig. 4, or fig. 5-7, it may be an "L" structure, and those skilled in the art will understand that the L-shaped structure is only one structural form of the conduction pipe 50, and simple modifications made in the actual process according to actual situations are also applicable to the present invention, such as the arc shape, or the arc shape at the corner of the L-shaped structure, etc.

For the first switch 121 and/or the second switch 122 in fig. 3, or fig. 4, or any one of the embodiments of fig. 5 to 7, it may be any one of a gate, a weir gate, a valve, a gate valve, an airbag, a gas pillow, a pipe clamp valve, or a flexible cut-off device, the present invention is not limited, as long as the mechanism for switching on or off the conduction pipe can be implemented, and the present invention is also within the protection scope of the present invention.
