Example one

Specifically, referring to fig. 1 to 3, in an embodiment of the sewage storage apparatus, the sewage storage apparatus at least includes a regulating portion 10, a buffering portion 40 and a vacuum pump 130.

Wherein, the adjusting part 10 is internally provided with an adjusting space for accommodating sewage and is respectively communicated with the sewage outlet of the unit area and the confluence pipe 30; the size and volume of the adjusting part 10 are not limited in the invention, and can be flexibly designed according to actual operation requirements. Similarly, the buffer part 40 also has a storage space 401 for storing the above-mentioned sewage therein, and is communicated with the adjusting part 10; the size and volume of the storage space 401 are not limited in the present invention, and may be flexibly designed according to actual operation requirements. Therefore, the buffer part 40 and the adjusting part 10 constitute a dual-region structure of the storage device, wherein the bottom elevation of the part where the buffer part 40 and the adjusting part 10 are communicated can be lower than the bottom elevation of the part where the adjusting part 10 and the confluence pipe 30 are communicated; here, the portion where the buffer portion 40 communicates with the adjustment portion 10 may refer to a portion where the sewage is supplied from the buffer portion 40 to the adjustment portion 10 or the sewage is supplied from the adjustment portion 10 to the buffer portion 40. The vacuum pump 130 is a device for pumping the gas in the buffer 40 to form a vacuum-tight chamber in the buffer 40 and to form a gas pressure difference between the adjustment unit 10 and the buffer 40.

When the buffer part 40 needs to be filled with water, the vacuum pump 130 pumps the gas in the buffer part 40 to form a vacuum tight chamber in the buffer part 40, so that a gas pressure difference is formed between the adjusting part 10 and the buffer part 40, and the sewage in the adjusting part 10 is extruded to the buffer part 40 to be stored under the action of the gas pressure under the action of the pressure difference; the buffering part 40 is arranged above the adjusting part 10, so that a height difference, namely a gravity difference, is formed between the buffering part and the adjusting part, when the buffering part 40 needs to discharge water, the pressure difference disappears when the buffering part is communicated with the external atmospheric pressure, so that the sewage in the storage space 401 flows into the adjusting part 10 under the action of gravity and is discharged by the confluence pipe 30.

As an embodiment of the adjusting portion 10, it may include: the sewage treatment system comprises a regulation inlet 102, a first regulation outlet 103 and a second regulation outlet 104, wherein the regulation inlet 102 is used for being connected with a sewage outlet of a unit area and providing an input interface for sewage needing to be regulated, the first regulation outlet 103 is used for being connected with a confluence pipe 30 and providing an output interface for the sewage needing to be regulated, and the second regulation outlet 104 is connected with a buffer part 40.

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

As an embodiment of the vacuum pump 130, it may start a vacuum port 405 at the top of the buffer portion 40, and arrange a first valve 406 and a second valve 407 in parallel at the vacuum port 405; the vacuum pump 130 is communicated with the buffer part 40 through the first valve 406, the buffer part 40 is communicated with the external atmosphere through the second valve 407, so that when the buffer part needs to be filled with water, the first valve 406 is opened, the second valve 407 is closed, the buffer part 40 is vacuumized through the vacuum pump 130, a pressure difference is formed between the adjusting part and the buffer part, when the buffer part needs to be drained, the second valve 407 is opened, the buffer part 40 is communicated with the external atmosphere to recover the atmospheric pressure, and therefore the sewage stored in the buffer part 40 can flow into the adjusting part under the action of gravity. For the first valve 406 and the second valve 407 disposed at the vacuum port 405, in the embodiment of the present invention, the first valve 406 and the second valve 407 may be replaced by a two-position three-way electromagnetic valve, that is, the vacuum pump is communicated with the buffer portion 40 through the two-position three-way electromagnetic valve, so that the functions of vacuum pumping and communication with the atmospheric pressure are realized through the two-position three-way electromagnetic valve.

It should be noted that, for the above-mentioned adjusting inlet 102, first adjusting outlet 103, second adjusting outlet 104, and buffer ports 402, the aperture size and the respective orientations of the adjusting inlet, the first adjusting outlet 103, the second adjusting outlet 104, and the buffer ports 402 are not limited, and the present invention can be flexibly designed according to the actual operation requirements as long as the sewage can be communicated among the adjusting portion 10, and the buffer portion 40, and similarly, the number of the buffer portions 40 and the corresponding number of the buffer ports 402 are not limited in the embodiments of the present specification, and can be flexibly designed according to the actual water storage amount, and the present invention is not considered to be within the protection scope of the present invention because the aperture size, the orientations of the adjusting inlet, the adjusting outlet, the second adjusting outlet 104, and the buffer ports 402 are different.

As an 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 situations of rainfall and no rainfall for regulation, for example, if the sewage output by the regulation unit 10 directly enters the flow mixing pipe and then is mixed with the rainwater, when there is rainfall, 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, at this time, the sewage output by the adjusting part 10 can be adjusted by the sewage adjusting and storing device provided in the embodiment of the present specification when there is rainfall, and the sewage adjusting and storing can be stopped when there is no rainfall, that is, at this time, the sewage output by the adjusting part 10 is directly input to the confluence pipe 30;

that is, the adjusting inlet 102 of the adjusting part 10 is communicated with the sewage outlet in the unit area, and the adjusting part 10 is communicated with the buffering part 40, so that when the sewage needs to be adjusted and stored in the rainfall, the sewage output by the adjusting part 10 only needs to flow into the buffering part 40 through the buffering opening 402 for storage, so that only the rainwater exists in the flow combining pipe 30, and when the sewage needs to be output in the sunny day, the sewage stored in the buffering part 40 only needs to flow into the flow combining pipe 30 through the buffering opening 402 and the first adjusting outlet 103 in sequence, thereby effectively avoiding the technical defects that the sewage input by the adjusting part 10 directly enters the flow combining pipe to be output in the structural design of the rain day and the natural water body is easily seriously polluted, or the sewage treatment facility has overlarge treatment pressure, resource waste and the like in the prior art, and achieving the technical effect of adjusting and storing the sewage when the sewage does not need to be discharged, has 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, when the rainfall is relatively large, if the sewage output by the sewage branch pipe 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 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 regulating part 10 can be regulated by the sewage regulating and storing 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 regulating part 10 is directly inputted to the flow merging pipe 30 at this time.

That is, the adjusting inlet 102 of the adjusting part 10 is communicated with the water outlet in the unit area, and the adjusting part 10 is communicated with the buffering part 40, so that when the rainfall is large and the sewage needs to be adjusted and stored, only the sewage output by the adjusting part 10 flows into the buffering part 40 through the buffering opening 402 to be stored, so that only the rainwater with the large rainfall exists in the flow-combining pipe 30, and when the sewage needs to be output in fine days or with small rainfall, only the sewage stored in the buffering part 40 flows into the flow-combining pipe 30 through the buffering opening 402 and the first adjusting outlet 103, thereby effectively avoiding the technical defects that the sewage input by the adjusting part 10 directly enters the flow-combining pipe to be output in the structural design that the rainfall is large and the serious pollution of natural water is easily caused, or the technical defects of large treatment pressure of the sewage treatment facility, resource waste and the like, and being capable of adjusting and storing the sewage when the sewage does not need to be discharged, has the characteristics of simple structure, convenient operation and wide applicability.

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 requiring regulation", a liquid level interval threshold value is preset according to a liquid level height in the buffer portion 40, and the liquid level height in the buffer portion 40 is monitored in real time, so that when the liquid level height is lower than a minimum value of the interval threshold value, it is determined that the sewage requires regulation, that is, the sewage output by the regulating portion 10 at this time flows into the buffer portion 40 to be stored. When the liquid level is higher than the maximum value of the threshold value of the interval, the adjustment of the sewage can be stopped, that is, the sewage output by the adjusting part 10 is directly input into the flow merging pipe 30.

That is, the regulation inlet 102 of the regulation part 10 is communicated with the water outlet in the unit area, and the regulation part 10 is communicated with the buffer part 40, so that when the liquid level is lower than the minimum value of the interval threshold, it means that the storage space of the buffer part 10 is large at this time, and in order to reduce the transport pressure of the merging pipe, the treatment pressure of the sewage treatment facility, and the like, it is only necessary that the sewage output from the regulation part 10 flows into the buffer part 40 through the buffer port 402 for storage, when the liquid level of the buffer part 40 is relatively low, the sewage is stored, and when the liquid level is higher than the maximum value of the interval threshold, it means that the sewage stored in the buffer part 10 is about to overflow, and at this time, 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 regulation outlet 103 in sequence, and when the transport pressure of the merging pipe is effectively reduced, or the treatment pressure of the sewage, The condition that sewage overflows in the buffer part 40 can be effectively prevented while the technical defects such as resource waste and the like, and the safety is high.

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 sewage storage facility directly enters the flow merging pipe and is then directly transported to the sewage treatment plant in a non-rainfall period, or if the sewage is mixed with rainwater and is then transported to the sewage treatment plant in a rainfall period, the treated water entering the sewage treatment plant is too much to reach the upper limit of treatment in the sewage treatment plant, and overflow is likely to occur, so that the sewage output from the regulation unit 10 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, the sewage output from the regulation unit 10 may be 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 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.
