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

that is, the interception inlet 102 of the interception part 10 is communicated with the water outlet of the biochemical part 20, so that the sewage in the biochemical part 20 firstly enters the interception part 10 before entering the confluence pipe, and the interception part 10 is communicated with the buffer part 40, therefore, when the sewage needs to be regulated and stored in rainfall, the sewage output by the biochemical part 20 only needs to flow into the buffer part 40 through the buffer port 402 for storage, so that only rainwater exists in the confluence pipe 30, and when the sewage needs to be output in fine days, the sewage stored in the buffer part 40 only needs to flow into the confluence pipe 30 through the buffer port 402 and the first interception outlet 103, thereby effectively avoiding the technical defects that the sewage input by the biochemical part 20 directly enters the confluence pipe for output in rainy days, such as serious pollution of natural water body, overlarge treatment pressure of sewage treatment facilities, resource waste and the like, can reach the technical effect of regulation and storage to sewage when not needing sewage discharge, have simple structure, convenient operation and extensive applicability's characteristics.

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, when the rainfall is relatively large, if the sewage output by the biochemical part directly enters the flow mixing pipe and then is mixed with 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, when the rainfall is relatively large, the sewage outputted from the biochemical part 20 can be regulated by the sewage regulation and storage device provided in the embodiment of the present specification, and when the rainfall is relatively small, the sewage regulation and storage can be stopped, that is, the sewage outputted from the biochemical part 20 is directly inputted to the confluence pipe 30.

That is, the interception inlet 102 of the interception part 10 is communicated with the water outlet of the biochemical part 20, so that the sewage in the biochemical part 20 firstly enters the interception part 10 before entering the merging pipe, and the interception part 10 is communicated with the buffer part 40 through the buffer port 402 of the buffer part 40, therefore, when the rainfall is large and the sewage needs to be regulated and stored, only the sewage output by the biochemical part 20 flows into the buffer part 40 through the buffer port 402 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 fine days or with small rainfall, the sewage stored in the buffer part 40 only needs to flow into the merging pipe 30 through the buffer port 402 and the first interception outlet 103, thereby effectively avoiding the problem that the sewage input by the biochemical part 20 directly enters the merging pipe to be output, and easily causes natural and serious pollution to the water body when the rainfall is large, or the technical defects of overlarge treatment pressure, resource waste and the like of the sewage treatment facility can achieve the technical effect of regulating and storing the sewage when the sewage is not required to be discharged, and the sewage treatment facility has the characteristics of simple structure, convenience in operation and wide applicability.

When the liquid level is higher than the maximum value of the threshold value of the interval, the regulation and storage of the sewage can be stopped, that is, the sewage output by the biochemical part 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 biochemical part 20, so that the sewage in the biochemical part 20 firstly enters the intercepting part 10 before entering the confluence pipe, and the intercepting part 10 is communicated with the buffer part 40 through the buffer port 402 of the buffer part 40, so that when the liquid level 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, only the sewage output by the biochemical part 20 needs to flow into the buffer part 40 through the buffer port 402 for storage, the sewage is stored when the liquid level of the buffer part 40 is low, and when the liquid level is higher than the maximum value of the interval threshold, the sewage stored in the buffer part 10 at the moment is about to overflow, at the moment, the sewage stored in the buffer part 40 only needs to sequentially pass through the buffer port 402, The first cutoff outlet 103 may flow into the confluence pipe 30, so that technical defects such as the delivery pressure of the confluence pipe, the excessive treatment pressure of the sewage treatment facility, resource waste and the like are effectively reduced, and the overflow of the sewage in the buffer part 40 can be effectively prevented, thereby having the characteristic of high safety.

As another application environment of the embodiment of the present specification, a regulation node may be set according to whether there is surplus capacity in a sewage treatment plant for regulation, for example, when there is no surplus capacity in the sewage treatment plant, if the sewage output from the biochemical part directly enters the flow merging pipe and then is directly delivered to the sewage treatment plant in a non-rainfall period, or if the sewage is mixed with rainwater in a rainfall period and then is delivered to the sewage treatment plant, the treated water entering the sewage treatment plant is too much to reach the upper limit of the treatment of the sewage treatment plant, and overflow is likely to occur, so that at this time, the sewage output from the biochemical part 20 may be regulated by the sewage regulation device provided in the embodiment of the present specification, and when there is surplus capacity in the sewage treatment plant, the sewage regulation may be stopped, that is, at this time, the sewage output from the biochemical part 20 is directly input to the flow merging 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 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 invention is not limited thereto.

When the buffer part 40 needs to be filled with water, the sewage conveyed to the cut-off part 10 by the biochemical part 20 flows into the buffer part 40 under the action of self gravity to be stored; when the buffer 40 needs to discharge water, the gas source 120 charges compressed gas into the buffer 40 to form gas pressure in the buffer 40, so as to press the sewage flow in the buffer 40 to flow into the receiving space 101 and be discharged from the junction pipe 30. It is particularly emphasized that the level of the bottom of the buffer port 402 is lower than the level of the bottom of the first shut-off opening 103, and that the closer the buffer port 402 is to its bottom in the shut-off portion 10 the better,

The principle of sewage inflow and discharge from the buffer is connected to the principle of the split structure shown in fig. 1, and will not be described herein, in this embodiment, the same buffer port 402 has a lower bottom level than the first cut-off outlet 103, and the buffer port 402 is preferably closer to the bottom of the cut-off portion 10, so that enough sewage flows into the buffer 40 under gravity in the cut-off portion.

As still another implementation manner in the embodiments of the present disclosure, the biochemical portion 20 and the cut-off portion 10 may be an integrated structure as shown in fig. 4. The buffer part 40 and the integrated structure are distributed in a split mode. It is understood that the biochemical portion 20 at this time has 2 regions shown in FIG. 4, the left region of which is the biochemical portion 20 and the right region of which is the cut-off portion 10, which are independent of each other and communicate with each other through the cut-off inlet. The principle of the inflow and discharge of sewage into and from the buffer is connected to the principle in the above-described construction according to fig. 1-3, and will not be described in detail here, in which embodiment the same buffer opening 402 has a lower bottom level than the first cut-off opening 103, and the buffer opening 402 is preferably located as close as possible in the cut-off portion 10 to the bottom thereof, so that sufficient sewage flows into the buffer 40 in the cut-off portion under the influence of gravity.

As still another implementation manner in the embodiments of the present disclosure, the buffering portion 40 and the intercepting portion 10 may be an integrated structure as shown in fig. 5 to 6, the biochemical portion 20 is a septic tank, and the buffering portion 40 and the intercepting portion 10 are two separate areas in the biochemical portion 20, both of which are inside the biochemical portion 20. The left area is the biochemical part 20, the right area is the cut-off part 10, the middle area is the buffer part 40, the three parts are independent, the sewage flows into the buffer part and is discharged from the buffer part, the principle mode is communicated with the principle mode in the structure shown in the above-mentioned figures 1-3, the details are not repeated, in the embodiment, the bottom elevation of the same buffer port 402 is lower than the bottom elevation of the first cut-off outlet 103, and the closer the buffer port 402 is to the bottom of the cut-off part 10, the better, the more the sewage in the cut-off part can flow into the buffer part 40 under the gravity.
