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 by the sewage storage facility 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 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 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 sewage containing facility 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 sunny 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 serious pollution of natural water caused by the structural design that the sewage input by the sewage containing facility 20 directly enters the confluence pipe for output in rainy days in the prior art, 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.

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 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 regulation and storage of the sewage are needed, only the sewage output by the sewage containing facility 20 flows into the buffer part 40 through the buffer port 402 for storage, only the rainwater with large rainfall exists in the merging pipe 30, and when the sewage is needed to be output in a clear day or with small rainfall, only the sewage stored in the buffer part 40 flows into the merging pipe 30 through the buffer port 402 and the first outflow port 103, so that the serious pollution of the natural water body caused by the structural design that the sewage input by the sewage containing facility 20 directly enters the merging pipe for output in a large rainfall is effectively avoided, 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.

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.

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 cut-off inlet 102 of the cut-off part 10 is communicated with the water outlet of the sewage storage facility 20 in the unit area, so that the sewage in the sewage storage facility 20 firstly enters the cut-off part 10 before entering the confluence pipe, and the cut-off 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, and 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 storage facility 20 only needs to flow into the buffer part 40 through the buffer port 402 for storage, so that 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 is about to overflow, and 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 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 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.
