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 mechanism 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.
