The size and volume of the overflow water inlet area 202 and the overflow water outlet area 201 are not limited in the present invention, and can be flexibly designed according to actual operation requirements.

As an implementation manner of the embodiment of the present invention, please refer to fig. 1-2, the sewage storage apparatus further includes: a first through pipe 203, the first through pipe 203 communicating the overflow water inlet area 202 with the cut-off part 10. The cut-off portion 10 may then comprise: the system comprises a cut-off inlet 102, a first cut-off outlet 103 and a second cut-off outlet 104, wherein the cut-off inlet 102 is used for being communicated with the overflow water outlet area 201, the first cut-off outlet 103 is used for being connected with a confluence pipe and used for providing an output interface for sewage needing to be regulated, and the second cut-off outlet 104 is communicated with a first straight pipe 203.

As an implementation manner for controlling the circulation of the sewage in the embodiment of the present specification, the sewage storage device further includes: a first switch 121 disposed at the first cutoff outlet 103; a second switch 122 disposed at the second shut-off outlet 104. The first switch 121 and the second switch 122 may be any one of a gate, a weir gate, a valve, a gate valve, an air bag, an air pillow, a pipe clamp valve, or a flexible shutoff device, and the present invention is not limited thereto, and any mechanism capable of turning on or off an inlet and an outlet is suitable for the present invention and is within the protection scope of the present invention.

As an application environment of the embodiment of the present specification, for the above-mentioned sewage, a regulation node may be set according to the situations of rainfall and no rainfall for regulation, for example, if the sewage output from the unit area directly enters the flow mixing pipe and then is mixed with the rainwater in the presence of rainfall, the mixed water of the rainwater and the sewage is easily polluted seriously when being directly discharged into the natural water body, and if being directly discharged into the sewage treatment facility for treatment, a large amount of clean rainwater in rainy days enters the sewage treatment facility for unnecessary treatment, which results in resource waste. Therefore, the sewage output by the unit area can be regulated and stored by the sewage regulation and storage device provided by the embodiment of the specification when rainfall occurs, and the sewage regulation and storage can be stopped when no rainfall occurs, namely, the sewage output by the unit area is directly input to the flow merging pipe 30;

that is, when the rainfall needs to regulate and store the sewage, the first switch 121 is turned off, and certainly, the second switch can be turned off synchronously, at this time, the overflow water outlet area 201 is connected with the sewage outlet of the unit area, so that the sewage in the unit area firstly flows into the overflow water outlet area 201, the water level in the overflow water outlet area 201 continuously rises along with the continuous inflow of the sewage until the water level exceeds the maximum capacity liquid level of the overflow water outlet area 201, and the overflow water inlet area 202 receives and stores the overflow sewage, thereby achieving the purpose of storing the sewage in the rainy day; when sewage does not need to be regulated and stored in fine days, the first switch and the second switch are opened at the moment, only the sewage passes through the first straight pipe 203 under the action of self gravity, the overflow water inlet area 202 flows into the cut-off part 10 through the first straight pipe 203 and finally flows out through the flow merging pipe 30, the technical defects that the sewage input by the sewage containing facility 20 in the prior art directly enters the flow merging pipe to be output in rainy days, the natural water body is extremely easy to cause serious pollution, the sewage treatment facility has overlarge treatment pressure, the resource waste and the like are effectively overcome, the technical effect of regulating and storing the sewage when the sewage is not required to be discharged is achieved, and the sewage treatment device has the characteristics of simple structure, convenience in operation and wide applicability.

As another application environment of the embodiment of the present specification, for the above-mentioned sewage, a regulation node may be set according to the size of rainfall for regulation, for example, when the rainfall is relatively large, if the sewage output from the unit area directly enters the flow mixing pipe and then is mixed with the rainwater, the mixed water of the rainwater and the sewage is easily polluted seriously when being directly discharged into the natural water body, and if being directly discharged into the sewage treatment facility for treatment, a large amount of relatively clean rainwater in rainy days enters the sewage treatment facility for unnecessary treatment, which results in resource waste. Therefore, at this time, the sewage output from the unit area can be regulated by the sewage regulation and storage device provided in the embodiment of the present specification when the rainfall is relatively large, and the sewage regulation and storage can be stopped when the rainfall is relatively small, that is, the sewage output from the unit area is directly input to the flow merging pipe 30 at this time.

That is, when the sewage needs to be regulated, the first switch 121 is turned off, and certainly, the second switch can be turned off synchronously, at this time, the overflow water outlet area 201 is connected with the sewage outlet of the unit area, so that the sewage in the unit area firstly flows into the overflow water outlet area 201, the water level in the overflow water outlet area 201 continuously rises along with the continuous inflow of the sewage until the water level exceeds the maximum capacity liquid level of the overflow water outlet area 201, and the overflow water inlet area 202 receives and stores the overflow sewage, thereby achieving the purpose of storing the sewage when the rainfall is relatively large; and when rainfall ratio need not carry out the regulation to sewage, open first switch and second switch this moment, only need sewage through first straight-through pipe 203 under self action of gravity, by the regional 202 warp of overflow intaking first straight-through pipe 203 flows in the damming portion 10 to finally flow out by the confluence pipe 30, effectually avoided among the prior art to the sewage of acceping facility 20 input by sewage directly get into the structural design place that the confluence pipe exported and very easily cause natural water serious pollution when the rainy day, perhaps sewage treatment facility treatment pressure is too big, technical defect such as wasting of resources, can reach the technological effect of carrying out the regulation to sewage when not needing sewage discharge, have simple structure, convenient operation and extensive applicability's characteristics.

Those skilled in the art can understand that, regarding the magnitude and the size of the rainfall, the present invention is not limited, and the rainfall parameter threshold may be set according to the actual operation requirement for defining.

As another application environment of the embodiment of the present specification, for the above-mentioned sewage, a liquid level interval threshold is preset according to a liquid level height in an overflow water inlet area, and the liquid level height in the overflow water inlet area is monitored in real time, so that when the liquid level height is lower than a minimum value of the interval threshold, it is determined that the sewage needs to be regulated, that is, the sewage output by the unit area flows into the overflow water inlet area to be stored. When the liquid level is higher than the maximum value of the threshold value of the interval, the sewage storage can be stopped, namely, the sewage output by the unit area is directly input into the flow merging pipe 30 at the moment.

That is, when the sewage needs to be regulated, the first switch 121 is turned off, and of course, the second switch can be turned off synchronously, at this time, the overflow outlet area 201 is connected with the sewage outlet of the unit area, so that the sewage in the unit area firstly flows into the overflow outlet area 201, as the sewage continues to flow in, the water level in the overflow outlet area 201 continuously rises until the water level exceeds the maximum capacity liquid level of the overflow outlet area 201, overflow occurs, and the overflow inlet area 202 receives and stores the overflow sewage, so that when the liquid level is lower than the minimum value of the interval threshold value, the storage space of the overflow inlet area is large at this time, and the sewage is stored in order to reduce the delivery pressure of the flow merging pipe, the treatment pressure of the sewage treatment facility and the like; the technical defects of high conveying pressure of the confluence pipe, excessive treatment pressure of a sewage treatment facility, resource waste and the like are effectively overcome.

As another application environment of the embodiment of the present specification, a regulation node may be set to regulate according to whether a sewage treatment plant has spare capacity, for example, if the sewage from the unit area directly enters the confluence pipe when the sewage treatment plant has no spare capacity, the treated water is directly conveyed to a sewage treatment plant in the non-rainfall period or is mixed with rainwater and then conveyed to the sewage treatment plant in the rainfall period, so that the treated water entering the sewage treatment plant is excessive to reach the upper treatment limit of the sewage treatment plant, overflow is easy to occur, therefore, the sewage output by the sewage housing facility 20 can be regulated by the sewage regulating and storing device provided in the embodiment of the present specification, when the sewage treatment plant has a surplus capacity, the sewage storage can be stopped, that is, the sewage output from the sewage storage facility 20 is directly input into the confluence pipe 30.

It should be noted that the above description of the four application environments of the sewage storage device in the drainage system provided in the embodiment of the present disclosure is only an example of the practical application of the sewage storage device, and is not a limitation to the use, and those skilled in the art can also understand that the sewage storage device provided in the embodiment of the present disclosure may also be applied to other application environments that need to store and store sewage, or a combination of the four application environments, besides the above four application environments, in the drainage system, including other application scenarios that can also be applied to a specific application scenario other than the drainage system, and the present disclosure is not limited thereto. In other words, any application environment or application scenario that can store and adjust the sewage is suitable for the present invention and is within the scope of the present invention.

As another implementation manner of the embodiment of the present invention, referring to fig. 3 to 4, the sewage storage and regulation device may further include: a pump 205 disposed in the overflow inlet area 202 to pump sewage in the overflow inlet area 202 to the cut-off portion 10. The cut-off portion 10 may then comprise: the intercepting inlet 102 and the first intercepting outlet 103 are arranged, the intercepting inlet 102 is used for being communicated with the overflow water outlet area 201, and the first intercepting outlet 103 is used for being connected with a confluence pipe and providing an output interface for sewage needing to be regulated. As an embodiment for controlling the circulation of the sewage in this kind of embodiment, the sewage storage apparatus further includes: a first switch 121 disposed at the first cutoff outlet 103. The first switch 121 may be any one of a gate, a weir gate, a valve, a gate valve, an air bag, an air pillow, a pipe clamp valve, or a flexible cut-off device, and the present invention is not limited thereto, and any mechanism capable of turning on or off the inlet and the outlet is suitable for the present invention and is within the protection scope of the present invention.

It should be noted that, regarding the working principle and mode of the embodiment in the above four application environments are basically the same, and are not described herein again, but the difference is that in the embodiment, when the overflow water inlet area 202 is required to drain water, the sewage is pumped into the cut-off portion 10 only by a pump, so as to achieve the purpose of omitting the first through pipe 203.

As another implementation manner of the embodiment of the present invention, referring to fig. 5 to 6, the sewage storage apparatus may further include: a flap valve 205, which is arranged at a position where the overflow water inlet area 202 is separated from the overflow water outlet area 201, wherein the sewage in the overflow water inlet area 202 flows into the overflow water outlet area 201 from the overflow water inlet area 202 through the flap valve under the action of gravity; a second through pipe 204 connecting the overflow outlet area 201 and the cut-off part 10, wherein the sewage in the overflow outlet area 201 flows into the cut-off part 10 from the overflow outlet area 20 through the second through pipe 204 under the action of gravity. The cut-off portion 10 may then comprise: the system comprises a cut-off inlet 102, a first cut-off outlet 103 and a second cut-off outlet 104, wherein the cut-off inlet 102 is used for being communicated with the overflow water outlet area 201, the first cut-off outlet 103 is used for being connected with a confluence pipe and used for providing an output interface for sewage needing to be regulated, and the second cut-off outlet 104 is communicated with a second straight-through pipe 204. As an embodiment for controlling the circulation of the sewage in this kind of embodiment, the sewage storage apparatus further includes: a first switch 121 disposed at the first intercepting outlet 103, and a second switch 122 disposed at the second intercepting outlet 104. The first switch 121 may be any one of a gate, a weir gate, a valve, a gate valve, an air bag, an air pillow, a pipe clamp valve, or a flexible cut-off device, and the present invention is not limited thereto, and any mechanism capable of turning on or off the inlet and the outlet is suitable for the present invention and is within the protection scope of the present invention.

It should be noted that, regardless of the above-mentioned one embodiment of the sewage storage apparatus shown in fig. 1-2, the other embodiment of the sewage storage apparatus shown in fig. 3-4, or the other embodiment of the sewage storage apparatus shown in fig. 5-6, the first switch 121 only limits whether the sewage in the cut-off portion 10 flows into the downstream pipeline through the flow merging pipe, and does not limit the storage function of the sewage in the septic tank in the embodiment of the present disclosure, so those skilled in the art can understand that, in the actual operation process, in order to simplify the structure of the apparatus, the technical solution of removing the first switch 121 is also applicable to the present disclosure, and should not be different from the present disclosure in that the first switch 121 is removed. In addition, when the sewage in the overflow water inlet area 202 is discharged to the cut-off part 10, in order to prevent the water discharged to the cut-off part 10 from flowing backward to the overflow water outlet area 201 and being unable to be discharged normally, in this embodiment of the present disclosure, a third switch 123 (an embodiment of the sewage storage device shown in fig. 7-8) may be disposed at the cut-off inlet 102 at a position where the overflow water outlet area 201 communicates with the cut-off part 10, and when the water in the overflow water inlet area 202 needs to be discharged, the third switch 123 is closed, and when the overflow water inlet area 202 needs to be stored, or when the sewage or the rainwater or the mixed water of the sewage and the rainwater is normally discharged from the overflow water outlet area 201 to the flow closing pipe through the cut-off part 10, the third switch 123 may be opened; similarly, the third switch 123 may be any one of a gate, a weir gate, a valve, a gate valve, an air bag, an air pillow, a pipe clamp valve, or a flexible cut-off device, and the present invention is not limited thereto, and any mechanism capable of turning on or off the inlet and the outlet is suitable for the present invention and is within the protection scope of the present invention.

Of course, as another implementation manner, it is also possible to provide a fixed weir in the cut-off portion 10 near the cut-off inlet 102, and the top elevation of the fixed weir is higher than the bottom elevation of the cut-off inlet 102, so as to prevent the water discharged into the cut-off portion 10 from flowing back into the overflow outlet area 201 and being unable to be discharged normally by using the fixed weir instead of the third switch 123. For the fixed weir, any one of the prior art that can realize the function of blocking water flow may be used, and the invention is not limited.

It should be noted that, in this embodiment, when the overflow water inlet area 202 is required to perform drainage, the flap valve in the overflow water inlet area is firstly passed through, the overflow water inlet area 202 flows into the overflow water outlet area 201 through the flap valve, and then the sewage in the overflow water outlet area 201 flows into the cut-off portion 10 through the second straight pipe 204 from the overflow water outlet area 20 under the action of gravity. Preferably, the height of the second shut-off outlet 104 is lower than the height of the bottom of the shut-off inlet 102, so that the sewage overflowing the water outlet area 20 can smoothly flow into the shut-off portion 10 under the action of gravity.

if the liquid level data is less than or equal to the minimum liquid level value of the interval, controlling the first switch to be closed;

and if the liquid level data is greater than or equal to the maximum interval liquid level value, controlling the first switch to be turned on.

In this embodiment, that is, when the sewage needs to be regulated, the first switch 121 is turned off, and the second switch is also turned off synchronously, at this time, the overflow outlet area 201 is connected to the outlet of the unit area for discharging sewage, so that the sewage in the unit area flows into the overflow outlet area 201 first, as the sewage continues to flow in, the water level in the overflow outlet area 201 rises continuously until the water level exceeds the maximum capacity liquid level of the overflow outlet area 201, and the overflow outlet area 202 receives and stores the overflow sewage, thereby achieving the purpose that when the liquid level is lower than the minimum value of the interval threshold value, the storage space of the overflow inlet area is large at this time, and the sewage is stored for reducing the delivery pressure of the confluence pipe, the treatment pressure of the sewage treatment facility, and the like; the technical defects of high conveying pressure of the confluence pipe, excessive treatment pressure of a sewage treatment facility, resource waste and the like are effectively overcome.
