Wherein, the cut-off part 10 is internally provided with a containing space 101 for containing sewage and is respectively communicated with the sewage containing facility 20 and the confluence pipe 30; this size, the volume of collecting space 101 the utility model discloses do not restrict, can be according to the nimble design of actual operation demand can. Similarly, the buffer part 40 also has a storage space 401 for storing the above-mentioned sewage therein, and is communicated with the cut-off part 10; this storage space 401's size, volume the utility model discloses do not restrict, can be according to the nimble design of actual operation demand can. The intercepting part 10 is internally provided with a containing space 101 for containing sewage and is respectively communicated with the sewage containing facility and the confluence pipe; wherein, the bottom elevation of the communicating part of the buffering part 40 and the cut-off part 10 is lower than that of the communicating part of the cut-off part 10 and the confluence pipe 30; the portion where the buffering portion 40 communicates with the cut-off portion 10 may refer to a portion where the sewage is delivered from the buffering portion 40 to the cut-off portion 10 or from the cut-off portion 10 to the buffering portion 40. The gas source 120 is a device for charging the cut-off portion 10 with gas.

When the buffer part 40 needs to be filled with water, the air source 120 fills air into the cut-off part 10, so that sewage in the cut-off part 10 in a sealed state is extruded to the buffer part 40 to be stored through air pressure acting force; when the buffer part 40 needs to discharge water, since the sewage in the cut-off part 10 is continuously lowered along with the discharge of the flow-joining pipe 30, the sewage in the storage space 401 flows into the receiving space 101 by gravity and is discharged by the flow-joining pipe 30.

As an embodiment of the cut-off portion 10, it may include: the sewage treatment 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 connected with a sewage containing facility and providing an input interface for sewage to be regulated, the first cut-off outlet 103 is used for being connected with the confluence pipe 30 and providing an output interface for the sewage to be regulated, and the second cut-off outlet 104 is connected with the buffer part 40 and is used for conveying the sewage input by the cut-off inlet 102 to the buffer part 40 through the second cut-off outlet 104 for storage.

As an embodiment of the buffer portion 40, it may include: the bottom level of the buffer port 402 is lower than the bottom level of the first cutoff outlet 103, so that when the sewage input by the sewage input mechanism needs to be regulated, the sewage in the cutoff part 10 flows into the buffer part 40 through the second cutoff outlet 104 and the buffer port 402 in sequence for storage, and when the sewage in the buffer part 40 needs to be discharged, the sewage stored in the buffer part 40 only needs to flow into the cutoff part 10 through the buffer port 402 and the second cutoff outlet 104 in sequence, and is discharged into the confluence pipe 30 through the first cutoff outlet 103.

It should be noted that, to the above-mentioned import 102, first shut off export 103, second shut off export 104, buffering mouth 402 that dams, the utility model discloses do not limit to its bore size, the position of seting up on its carrier separately, can the nimble design of actual operation demand can, as long as can realize sewage accept

facility

As an application environment of the embodiment of the present specification, the "sewage requiring regulation" may be regulated by setting a regulation node according to the situations of rainfall and no rainfall, for example, if the sewage output by the sewage storage facility directly enters the flow mixing pipe and then is mixed with the rainwater, the mixed water of the rainwater and the sewage is easily seriously polluted when being directly discharged into the natural water body, and if the mixed water is 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 sewage storage facility 20 can be stored by the sewage storage device provided in the embodiment of the present specification when there is rainfall, and the sewage storage can be stopped when there is no rainfall, that is, the sewage output by the sewage storage facility 20 is directly input to the confluence pipe 30;

that is, the interception inlet 102 of the interception part 10 is communicated with the water outlet of the sewage containing facility 20 in the unit area, so that the sewage in the sewage containing facility 20 firstly enters the interception part 10 before entering the confluence pipe, and is communicated with the second interception outlet 104 through the buffer port 402 of the buffer part 40, so as to realize the communication between the interception part 10 and the buffer part 40, therefore, when the sewage needs to be regulated and stored in rainfall, the sewage output by the sewage containing facility 20 only needs to flow into the buffer part 40 through the second interception outlet 104 and the buffer port 402 in sequence, so that only the rainwater exists in the confluence pipe 30, and when the sewage is required to be output in sunny days, the sewage stored in the buffer part 40 only needs to flow into the confluence pipe 30 through the buffer port 402, the second interception outlet 104 and the first interception outlet 103 in sequence, thereby effectively avoiding the structural design existing in the prior art that the sewage input by the sewage containing facility 20 directly enters the confluence pipe to be output in rainy days and is very easy to be output in rainy days The sewage treatment system has the advantages of causing serious pollution to natural water bodies or having technical defects of overlarge treatment pressure of sewage treatment facilities, resource waste and the like, achieving the technical effect of regulating and storing the sewage when the sewage is not required to be discharged, and having the characteristics of simple structure, convenient operation and wide applicability.

As another application environment of the embodiment of the present specification, for the above-mentioned "sewage requiring regulation", a regulation node may be set according to the magnitude of rainfall for regulation, for example, if the rainfall is relatively large, if the sewage output by the sewage storage facility directly enters the flow mixing pipe and then is mixed with the rainwater, the mixed water of the rainwater and the sewage is discharged directly into the natural water body, which is very likely to cause serious pollution to the received water body, and if the sewage is discharged directly 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 discharged from the sewage storage facility 20 may be stored by the sewage storage device provided in the embodiment of the present specification when the rainfall is relatively large, and the sewage storage may be stopped when the rainfall is relatively small, that is, the sewage discharged from the sewage storage facility 20 may be directly input to the confluence pipe 30.

That is, the interception inlet 102 of the interception part 10 is communicated with the water outlet of the sewage containing facility 20 in the unit area, so that the sewage in the sewage containing facility 20 firstly enters the interception part 10 before entering the merging pipe, and is communicated with the second interception outlet 104 through the buffer port 402 of the buffer part 40 to realize the communication between the interception part 10 and the buffer part 40, thus when the rainfall is large and the sewage needs to be regulated, only the sewage output by the sewage containing facility 20 sequentially passes through the second interception outlet 104 and the buffer port 402 to flow into the buffer part 40 for storage, so that only the rainwater with large rainfall exists in the merging pipe 30, and when the sewage is needed to be output in sunny days or with small rainfall, only the sewage stored in the buffer part 40 sequentially passes through the interception buffer port 402, the second interception outlet 104 and the first interception outlet 103 to flow into the merging pipe 30, the technical defects that the sewage input by the sewage containing facility 20 directly enters the confluence pipe to be output by a structural design, when the rainfall is large, the natural water body is extremely easy to cause serious pollution, or the sewage treatment facility has overlarge treatment pressure, resource waste and the like are effectively avoided, the technical effect of regulating and storing the sewage when the sewage is not required to be discharged can be achieved, and the sewage treatment device has the characteristics of simple structure, convenience in operation and wide applicability.

Those skilled in the art can understand that, for the size of the rainfall, the utility model discloses do not do the restriction, can set for the rainfall parameter threshold according to the actual operation demand and define can.

As another application environment of the embodiment of the present specification, the "sewage requiring regulation" may be that a liquid level interval threshold is preset according to the liquid level height in the buffer unit 40, and the liquid level height in the buffer unit 40 is monitored in real time, so that when the liquid level height is lower than the minimum value of the interval threshold, it is determined that the sewage needs to be regulated, that is, the sewage output by the sewage storage facility 20 at this time flows into the buffer unit 40 to be stored. When the liquid level is higher than the maximum value of the threshold value of the interval, the adjustment and storage of the sewage can be stopped, that is, the sewage output by the sewage containing facility 20 is directly input into the confluence pipe 30.

That is, the intercepting inlet 102 of the intercepting part 10 is communicated with the water outlet of the sewage containing facility 20 in the unit area, so that the sewage in the sewage containing facility 20 firstly enters the intercepting part 10 before entering the confluence pipe, and is communicated with the second intercepting outlet 104 through the buffer port 402 of the buffer part 40 to realize the communication between the intercepting part 10 and the buffer part 40, so that when the liquid level height is lower than the minimum value of the interval threshold, the storage space of the buffer part 10 is large at the moment, in order to reduce the conveying pressure of the confluence pipe, the treatment pressure of the sewage treatment facility and the like, the sewage output by the sewage containing facility 20 only needs to flow into the buffer part 40 through the second intercepting outlet 104 and the buffer port 402 in sequence to be stored, the sewage is stored when the liquid level of the buffer part 40 is relatively low, and when the liquid level height is higher than the maximum value of the interval threshold, the sewage stored in the buffer part 10 is about to overflow at the moment, at this time, only the sewage stored in the buffer part 40 sequentially passes through the buffer port 402, the second intercepting outlet 104 and the first intercepting outlet 103 and flows into the confluence pipe 30, so that the technical defects of the confluence pipe, overlarge treatment pressure of a sewage treatment facility, resource waste and the like are effectively reduced, the overflow of the sewage in the buffer part 40 can be effectively prevented, and the buffer part has the characteristic of high safety.

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, when the sewage treatment plant has no spare capacity, if the sewage output by the sewage storage facility directly enters the confluence pipe, 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 specification is only an example of the practical application of the sewage storage device, and does not constitute 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 specification can also be applied to other application environments that need to store and store sewage, or a combination of the three application environments, besides the above three 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 invention is not limited thereto.
