Description

Technical Field

[0001] The invention belongs to the technical field of drainage, and in particular relates to a sewage treatment device. Background Art

[0002] The urban pipe network is divided into a combined sewer system and a separate sewer system, which are used to discharge sewage (such as domestic sewage) within the unit area. In the existing discharge process, the sewage in the unit area is first transported to the septic tank through the sewage branch pipe for collection and chemical treatment (such as chemical decomposition in the septic tank), so that the treated upper layer liquid flows into the municipal pipeline through the sewage pipe for subsequent treatment.

[0003] However, this discharge method means that when sewage is discharged, the sewage output from the septic tank directly enters the sewage pipe and mixes with rainwater. If the mixed water of rainwater and sewage is discharged directly into natural water bodies on rainy days, it is very easy to cause serious pollution to the receiving water bodies. If it is discharged directly into sewage treatment facilities for treatment, a large amount of relatively clean rainwater on rainy days will enter the sewage treatment facilities for unnecessary treatment, resulting in a waste of resources.

[0049] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention; the "and / or" keyword involved in this implementation represents both and, or. In other words, A and / or B mentioned in the embodiments of this specification represent both A and B, and A or B, and describe the three states of A and B. For example, A and / or B means: only A is included but not B; only B is included but not A; A and B are included.

[0050] At the same time, in the embodiments of this specification, when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in the embodiments of this specification are for illustrative purposes only and are not intended to limit the present invention.

[0051] It should be noted that, in order to explain this specification in more detail so that those skilled in the art can understand this specification more clearly and understandably, and further support the technical problems to be solved by this specification and the corresponding technical effects that can be achieved, the following explanations are made for the terminology involved before introducing this specification:

[0052] "Unit area" refers to the area where sewage exists, such as residential areas, schools, office buildings, shopping malls, etc.; sewage branch pipes, "sewage pipes", are pipes used to transport rainwater, sewage, or mixed water of rainwater and sewage in the unit area pipeline; "first treatment area" refers to the sewage transported by the sewage branch pipes in the unit area. It can be a tank structure with treatment functions such as a septic tank; "bottom elevation" refers to the elevation value of the lowest layer of a certain part or component. "Top elevation" refers to the elevation value of the top layer of a certain part or component.

[0053] When the sewage treatment device provided in the embodiment of this specification is applied to the specific application scenario of the drainage system, the sewage treatment device can realize the regulation of sewage based on the air pressure input by the air source and the self-gravity of the sewage, that is, the discharge and storage of sewage. The drainage system may include sewage branch pipes, sewage pipes, municipal pipes, etc., and the sewage in the unit area is centrally transported to the sewage branch pipes.

[0054] Embodiment 1

[0055] For details, please refer to the attached Figure 1-2 In the implementation manner of the sewage treatment device, the sewage treatment device at least includes a flexible intercepting mechanism 10, a first treatment area 20 and a second treatment area 40.

[0056] The first treatment area 20 and the second treatment area 40 are two independent areas of the sewage treatment unit. It can be understood that the first treatment area 20 is Figure 1 In the left part, the second processing area 40 is Figure 1In the right part of the figure, the first treatment area 20 has a storage space 101 for storing sewage, and is connected to the second treatment area 40 and the sewage pipe 30 respectively; the size and volume of the storage space 101 are not limited by the present invention, and can be flexibly designed according to actual operation requirements. Similarly, the second treatment area 40 also has a storage space 401 for storing the above-mentioned sewage, and is connected to the storage space 101; the size and volume of the storage space 401 are not limited by the present invention, and can be flexibly designed according to actual operation requirements. Among them, the bottom elevation of the part where the second treatment area 40 is connected to the first treatment area 20 is lower than the bottom elevation of the part where the first treatment area 20 is connected to the sewage pipe 30; here, the part where the second treatment area 40 is connected to the first treatment area 20 can refer to the part where sewage is transported from the second treatment area 40 to the first treatment area 20 or from the first treatment area 20 to the second treatment area 40. The second treatment area 40 can be connected to an external air source. The air source is a device that fills compressed gas into the second treatment area 40 to form air pressure in the second treatment area 40, thereby squeezing the sewage in the second treatment area 40 to flow toward the first treatment area 20. That is, the gas pressure formed by the air pressure filled in by the air source can be understood as the driving force described in this specification.

[0057] As an implementation mode of the gas source, an exhaust pipe can be started at the top of the second treatment area 40, and a first valve and a second valve can be arranged in parallel at the exhaust pipe; and the gas source and the second treatment area 40 are connected through the first valve, and the second treatment area 40 is connected to the external atmospheric pressure through the second valve, so that when the second treatment area 40 needs to take in water, the first valve is closed and the second valve is opened, so that the sewage in the first treatment area 20 flows into the second treatment area 40 under the action of gravity, and when the second treatment area 40 needs to discharge water, the first valve is opened and the second valve is closed, and the gas source fills the second treatment area 40 with compressed gas to form air pressure in the second treatment area 40, thereby squeezing the sewage in the second treatment area 40 into the storage space 101, and discharged from the sewage pipe 30. Among them, in order to enable the sewage transported from the first treatment area to flow smoothly into the second treatment area through the intercepting portion under the action of gravity when water enters the second treatment area, with respect to the first valve and the second valve, in the embodiment of the present invention, a two-position three-way solenoid valve can also be used to replace the first valve and the second valve, that is, the vacuum pump is connected to the second treatment area 40 through the two-position three-way solenoid valve, so that the functions of vacuuming and connecting with atmospheric pressure can be realized through the two-position three-way solenoid valve.

[0058] As an application environment of the embodiments of this specification, for the "sewage that needs to be regulated" mentioned above, the regulation node can be set according to the situation of whether there is rainfall or not. For example, when it rains, if the sewage output from the first treatment area directly enters the sewage pipe and mixes with rainwater, then when the mixed water of rainwater and sewage is directly discharged into the natural water body, it is very easy to cause serious pollution to the receiving water body. If it is directly discharged into the sewage treatment facility for treatment, a large amount of relatively clean rainwater on rainy days will enter the sewage treatment facility for unnecessary treatment, resulting in a waste of resources. Therefore, at this time, when it rains, the sewage output from the first treatment area 20 can be regulated by the sewage treatment device provided in the embodiments of this specification, and the sewage regulation can be stopped when there is no rainfall, that is, the sewage output from the first treatment area 20 is directly input into the sewage pipe 30;

[0059] That is, when sewage needs to be stored during rainfall, the sewage output from the first treatment area 20 only needs to flow into the second treatment area 40 by gravity for storage, so that only rainwater exists in the sewage pipe 30. When sewage needs to be discharged on sunny days, the sewage stored in the second treatment area 40 only needs to flow into the sewage pipe 30 through the first treatment area. This effectively avoids the technical defects in the prior art that the sewage input from the first treatment area 20 directly enters the sewage pipe for output, which is very likely to cause serious pollution of natural water bodies on rainy days, or the sewage treatment facility has excessive treatment pressure and waste of resources. It can achieve the technical effect of storing sewage when sewage discharge is not needed, and has the characteristics of simple structure, convenient operation and wide applicability.

[0060] As another application environment of the embodiments of this specification, for the above-mentioned "sewage that needs to be regulated and stored", the regulation node can be set according to the amount of rainfall for regulation and storage. For example, when the rainfall is relatively large, if the sewage output from the first treatment area directly enters the sewage pipe and mixes with rainwater, then when the mixed water of rainwater and sewage is directly discharged into the natural water body, it is very easy to cause serious pollution to the receiving water body. If it is directly discharged into the sewage treatment facility for treatment, a large amount of relatively clean rainwater on rainy days will enter the sewage treatment facility for unnecessary treatment, resulting in a waste of resources. Therefore, at this time, when the rainfall is relatively large, the sewage output from the first treatment area 20 can be regulated and stored by the sewage treatment device provided in the embodiments of this specification, and the sewage regulation and storage can be stopped when the rainfall is relatively small, that is, at this time, the sewage output from the first treatment area 20 is directly input into the sewage pipe 30.

[0061] That is, when it is necessary to regulate and store sewage, the sewage output from the first treatment area 20 only needs to flow into the second treatment area 40 by gravity for storage, so that only rainwater exists in the sewage pipe 30, and when sewage needs to be discharged, the sewage stored in the second treatment area 40 only needs to flow into the sewage pipe 30 through the first treatment area 20. This effectively avoids the technical defects in the prior art that the sewage input from the first treatment area 20 directly enters the sewage pipe for output, which easily causes serious pollution of natural water bodies on rainy days, or the sewage treatment facility has excessive treatment pressure and waste of resources. It can achieve the technical effect of regulating and storing sewage when sewage discharge is not needed, and has the characteristics of simple structure, convenient operation and wide applicability.

[0062] Those skilled in the art will appreciate that the present invention does not limit the amount of rainfall, and the rainfall parameter threshold can be set according to actual operational requirements.

[0063] As another application environment of the embodiments of this specification, for the above-mentioned "sewage that needs to be regulated", it can be based on the liquid level height in the second treatment area 40, by pre-setting the liquid level interval threshold, and real-time monitoring the liquid level height in the second treatment area 40, so that when the liquid level height is lower than the minimum value of the interval threshold, it is considered that the sewage needs to be regulated, that is, at this time, the sewage output from the first treatment area 20 flows into the second treatment area 40 for storage. When the liquid level height is higher than the maximum value of the interval threshold, the sewage regulation can be stopped, that is, at this time, the sewage output from the first treatment area 20 is directly input into the sewage pipe 30.

[0064] That is, when it is necessary to regulate and store sewage, the sewage output from the first treatment area 20 only needs to flow into the second treatment area 40 by gravity for storage, so that only rainwater exists in the sewage pipe 30, and when sewage needs to be discharged, the sewage stored in the second treatment area 40 only needs to flow into the sewage pipe 30 through the first treatment area and the sewage outlet 170. This effectively avoids the technical defects in the prior art that the structural design of the sewage input from the first treatment area 20 directly enters the sewage pipe for output on rainy days, which is very likely to cause serious pollution of natural water bodies, or excessive treatment pressure and waste of resources in sewage treatment facilities. It can achieve the technical effect of regulating and storing sewage when sewage discharge is not needed, and has the characteristics of simple structure, convenient operation and wide applicability.

[0065] As another application environment of the embodiments of the present specification, the regulating and storage nodes can be set for regulation according to whether the sewage treatment plant has surplus capacity. For example, when the sewage treatment plant does not have surplus capacity, if the sewage output from the first treatment area directly enters the sewage pipe, it is directly transported to the sewage treatment plant during non-rainy periods, or is mixed with rainwater during rainy periods and then transported to the sewage treatment plant. At this time, too much treated water will enter the sewage treatment plant and reach the treatment upper limit of the sewage treatment plant, which is very likely to overflow. Therefore, at this time, the sewage output from the first treatment area 20 can be regulated and stored by the sewage treatment device provided in the embodiments of the present specification, and the sewage regulation and storage can be stopped when the sewage treatment plant has surplus capacity, that is, the sewage output from the first treatment area 20 is directly input into the sewage pipe 30.

[0066] It should be noted that the description of the above four application environments of the sewage treatment device provided in the embodiment of this specification in the drainage system is only an example of the actual application of the sewage treatment device, and does not constitute a use restriction. Those skilled in the art can also understand that the sewage treatment device provided in the embodiment of this specification can also be applied to the drainage system in addition to the above four application environments, other application environments that need to be used for storing and regulating sewage, or a combination of the above four application environments, including other application scenarios other than the specific application scenario of the drainage system, and the present invention does not limit this. In other words, as long as it is an application environment or application scenario that can realize the storage of sewage and achieve the technical effect of regulating and storing sewage, it is applicable to the present invention and is within the protection scope of the present invention.

[0067] As an implementation method in the examples of this specification, the first treatment area 20 is a septic tank; the second treatment area 40 is one of a storage tank, a box culvert, and a pipe culvert, and the two are independent of each other.

[0068] As an implementation method of controlling the flow of sewage in the embodiment of this specification, the sewage treatment device further includes: a flexible intercepting mechanism 10 disposed at the connection portion between the sewage pipe 30 and the first treatment area 20 .

[0069] For details, please continue to refer to Figure 3-10 The flexible intercepting mechanism 10 may include: a flexible sleeve 12 and a valve body 15. The flexible sleeve 12 has a chamber 11 for filling a filler; the valve body 15 has a flow channel 151 connected to the sewage pipe 30, and a slide groove 152 for the flexible sleeve 12 to slide up and down in the valve body 15; the flexible sleeve 12 is arranged in the slide groove 152 and is sealed with the valve body 15. The slide groove 152 is connected to the flow channel 151.

[0070] In the implementation of the flexible intercepting mechanism 10, the circulation channel 151 can be understood as a channel for sewage circulation after it is connected to the sewage pipe 30, and the flexible sleeve 12 can be a flexible airbag with contraction and expansion functions, and the expansion of the airbag is achieved by filling the chamber 11 inside the flexible sleeve 12 with fillers, or the contraction of the airbag is achieved by discharging the fillers from the chamber 11 inside the flexible sleeve 12. At the same time, the flexible sleeve 12 in the process of expansion or contraction can slide up and down in the slide groove 152 shown, that is, when the flexible sleeve 12 is expanded, it slides downward from the slide groove 152 to the circulation channel 151, and fits with the bottom of the circulation channel 151, then interception is achieved; and when the flexible sleeve 12 is contracted, it slides upward from the circulation channel 151 to the slide groove 152, and when the flexible sleeve 12 is contracted, it slides upward from the circulation channel 151 to the slide groove 152, and when the flexible sleeve 12 is contracted, it slides up and down in ... When it slides upward to be separated from the bottom of the circulation channel 151, the circulation channel 151 is gradually opened. Those skilled in the art will understand that such a structural design does not require the flexible sleeve 12 to be mounted on the outside of the steel outer cover as in the prior art, nor does it require the flexible sleeve 12 to envelop the entire steel outer cover. Instead, the flexible sleeve 12 only needs to slide in the slide groove 152 of the valve body 15 by expansion or contraction, which greatly reduces the fitting area between the flexible sleeve 12 and the circulation channel 151. Since the expansion or contraction movement area of ​​the flexible sleeve 12 moves longitudinally relative to the circulation channel 151 and does not occupy lateral space, when it is used in a diversion well, it does not need to be installed entirely horizontally in the well, and has the characteristic of occupying extremely small space.

[0071] In addition, in the process of achieving interception, since the flexible sleeve 12 slides downward from the slide groove 152 to the circulation channel 151 and fits with the bottom of the circulation channel 151 when expanding, the contact seal between the flexible sleeve 12 and the bottom of the circulation channel 151 is surface contact, which can achieve a better sealing effect compared with the point contact in the prior art, that is, to achieve a better interception effect. In order to ensure that the flexible sleeve 12 maintains a good seal during the expansion process and can expand for a long time in the expanded state, the flexible sleeve 12 arranged in the slide groove 152 in this embodiment is sealed and connected to the valve body 15.

[0072] As for the flexible sleeve 12, it can be a chamber 11 with an open port 121, and the open port 121 extends inward to form a closed structure. The open port 121 is adapted to the notch of the slide 152, and is sealed and connected to the notch of the slide 152 through the open port 121. Specifically, the open port 121 of the flexible sleeve 12 can be understood as an inlet for filling the chamber 11 with fillers, and the fillers enter the closed structure chamber 11 through the open port 121 and expand inside the chamber. When the fillers need to be discharged, they are also discharged from the open port 121. Those skilled in the art can understand that the open port 121 is adapted to the notch of the slide 152, that is, the size and shape correspond, so that the notch of the slide 152 can be sealed and connected through the open port 121.

[0073] It should be noted that in the embodiment of the present application, the flexible sleeve 12 is adapted to the shape of the slide groove 152 and fits with the inner wall of the slide groove 152. The inner wall of the slide groove 152 is inclined inwardly from one end of the groove toward the other end of the slide groove 152, that is, it is inclined inwardly in the vertical direction, and the port diameter of the groove is larger than the port diameter at the other end. It can be understood that at this time the flexible sleeve 12 is a prefabricated flexible sleeve 12, which is adapted to the shape of the slide groove 152, and the inner wall of the slide groove 152 is inclined inwardly from one end of the groove toward the other end of the slide groove 152, so that the interface of the slide groove 152 has a certain taper, so that the flexible sleeve 12 with a prefabricated shape can quickly expand to the bottom of the circulation channel and fit with it during the process of filling with filler, thereby improving the efficiency of interception.

[0074] Furthermore, in the embodiment of the flexible shut-off mechanism 10, the flexible shut-off mechanism 10 further includes: a pressure cap 13, which is fixed on the notch to seal the open port 121 and the notch; a through port 131 is provided on the pressure cap 13, through which the filler can be filled into or discharged from the chamber 11. In order to achieve a better sealing effect between the open port 121 and the slide groove 152, the notch is bent outwardly in a direction perpendicular to the sliding direction of the flexible sleeve 12, so that the two opposite side interfaces of the notch are L-shaped, and the open port 121 of the flexible sleeve 12 is extended outwardly in accordance with the bent portion of the notch, so that the pressure cap 13 is in accordance with the open port 121 extending outward, and is bolted to the bent portion of the slide groove 152 (such as screw connection, bolt connection, etc.). In this way, the open port 121 of the flexible sleeve 12 is completely sealed with the notch by the pressure cap 13 when the notch of the slide groove 152 is in the notch. At the same time, in order to enhance the fastening, a reinforcing rib plate 153 is provided at the bending position.

[0075] Of course, a flange can also be provided on the notch; and a flange connection portion adapted to the flange is provided on the open port 121; wherein the pressure cover 13 is attached to the flange connection portion and is flange-connected to the flange, and a reinforcing rib plate 153 is provided between the flange and the notch.

[0076] Those skilled in the art will understand that the sealing connection between the slot of the slide groove and the flexible sleeve can be a bolt connection of the above-mentioned L-shaped bending structure or a flange connection of the above-mentioned flange structure. The embodiments of the present application are not limited thereto. As long as the connection method can achieve a relatively sealed connection between the slot of the slide groove and the flexible sleeve, it is applicable to the present invention.

[0077] Among them, as for the distribution mode of the circulation channel 151 and the slide groove 152, the circulation channel 151 is distributed horizontally in the valve body 15, and the slide groove 152 is distributed longitudinally in the valve body 15, that is, the circulation channel 151 and the slide groove 152 are perpendicular to each other, and in order to strengthen the tightness, a reinforcing rib plate 153 is provided at the vertical intersection of the circulation channel 151 and the slide groove 152. Of course, those skilled in the art can understand that for the positional relationship between the circulation channel 151 and the slide groove 152, their mutually perpendicular distribution is not absolute. In the equivalent replacement embodiment, when the slide groove 152 has a certain deviation in the vertical direction relative to the circulation channel 151, or is directly inclined, it is equivalent to the expansion or contraction of the flexible sleeve 12. The moving area moves longitudinally or nearly longitudinally relative to the circulation channel 151, and does not occupy the lateral space. It can also be achieved that when it is applied to the diversion well, it does not need to be installed in the well in the horizontal direction, and has the characteristic of occupying very small space. Therefore, the structural position distribution relationship between the circulation channel 151 and the slide groove 152 is applicable in all embodiments of the present application and is also within the protection scope of the present invention.

[0078] Furthermore, in order to facilitate the quick installation between the circulation channel 151 and the pipeline, in the embodiment of the present application, two interfaces for externally connected pipelines are correspondingly provided at both ends of the circulation channel 151, and the two interfaces extend outward in the circulation direction of the circulation channel 151 (i.e., the transverse direction shown in the figure), and are correspondingly distributed on both sides of the slide groove 152. In this way, the two corresponding interfaces can be connected with the external pipeline bolts through the two corresponding interfaces, or directly inserted into the external pipeline and clamped therewith.

[0079] As another embodiment of the flexible intercepting mechanism 10, it may include: a flexible sleeve 12, a gate plate 14 and a valve body 15. The flexible sleeve 12 has a chamber 11 for filling a filler; the valve body 15 has a flow channel 151 for an external pipeline (such as the first water inlet or the first water outlet of the diversion well), and a slide groove 152 for the flexible sleeve 12 to slide up and down in the valve body 15; the gate plate 14 and the flexible sleeve 12 are both arranged in the slide groove 152; the gate plate 14 is fixedly connected to the flexible sleeve 12, and the flexible sleeve 12 is sealedly connected to the valve body 15; the slide groove 152 is connected to the flow channel 151.

[0080] Similarly, the circulation channel 151 can be understood as a channel for sewage circulation after it is connected to the pipe opening of the sewage pipe 30. The flexible sleeve 12 can be a flexible airbag with contraction and expansion functions, and the expansion of the airbag is achieved by filling the chamber 11 inside the flexible sleeve 12 with fillers, or the contraction of the airbag is achieved by discharging the fillers from the chamber 11 inside the flexible sleeve 12. At the same time, the flexible sleeve 12 in the process of expansion or contraction can slide up and down in the slide groove 152, and since the gate plate 14 is fixedly connected to the flexible sleeve 12, that is, when the flexible sleeve 12 expands, it drives the gate plate 14 to slide downward from the slide groove 152 to the circulation channel 151, and when the gate plate 14 fits with the bottom of the circulation channel 151, the flow is intercepted; and when the flexible sleeve 12 contracts, it drives the gate plate 14 to slide upward from the circulation channel 151 to the slide groove 152. In the process, when the gate plate 14 slides upward to separate from the bottom of the circulation channel 151, the circulation channel 151 is gradually opened; those skilled in the art can understand that such a structural design does not require the flexible sleeve 12 to be sleeved on the outside of the steel outer cover as in the prior art, nor does it require the flexible sleeve 12 to envelop the entire steel outer cover, but only requires the flexible sleeve 12 to slide in the slide groove 152 of the valve body 15 by expansion or contraction, which greatly reduces the fitting area between the flexible sleeve 12 and the circulation channel 151. Since the expansion or contraction movement area of ​​the flexible sleeve 12 moves longitudinally relative to the circulation channel 151 and does not occupy lateral space, when it is applied to the diversion well, it does not need to be installed in the well in its entirety horizontally, and has the characteristic of occupying very little space.

[0081] In addition, in the process of realizing interception, since the flexible sleeve 12 drives the gate plate 14 to slide downward from the slide groove 152 to the circulation channel 151 and fits with the bottom of the circulation channel 151 when expanding, the contact seal between the gate plate 14 and the bottom of the circulation channel 151 is surface contact, which can achieve better sealing effect compared with the point contact in the prior art, that is, to achieve better interception effect. In order to ensure that the flexible sleeve 12 maintains a good seal during the expansion process and can expand for a long time in the expanded state, the flexible sleeve 12 arranged in the slide groove 152 in this embodiment is sealed and connected to the valve body 15.

[0082] Similarly, the flexible sleeve 12 has an open port 121, and the open port 121 extends inward to form a closed structure chamber 11, the open port 121 is adapted to the notch of the slide 152, and is sealed and connected to the notch of the slide 152 through the open port 121. The top of the gate 14 is fixed to the other end of the flexible sleeve 12 opposite to the open port 121. Specifically, the open port 121 of the flexible sleeve 12 can be understood as an inlet for filling the chamber 11 with filler, the filler enters the closed structure chamber 11 through the open port 121, and expands inside the chamber, and when the filler needs to be discharged, it is also discharged from the open port 121. Those skilled in the art can understand that the open port 121 is adapted to the notch of the slide 152, that is, the size and shape correspond, so that the notch of the slide 152 can be sealed and connected through the open port 121.

[0083] Furthermore, in the embodiment of the flexible shut-off mechanism, it also includes: a pressure cap 13, which is fixed on the notch to seal the open port 121 and the notch; a through port 131 is provided on the pressure cap 13, through which the filling material can be filled into or discharged from the chamber 11. In order to achieve a better sealing effect between the open port 121 and the slide groove 152, the notch is bent outwardly in a direction perpendicular to the sliding direction of the flexible sleeve 12, so that the two opposite side interfaces of the notch are L-shaped, and the open port 121 of the flexible sleeve 12 is extended outwardly in accordance with the bent portion of the notch, so that the pressure cap 13 is in accordance with the open port 121 extending outward, and is bolted to the bent portion of the slide groove 152 (such as screw connection, bolt connection, etc.). In this way, the open port 121 of the flexible sleeve 12 is completely sealed with the notch by the pressure cap 13 when the notch of the slide groove 152 is in the notch. At the same time, in order to enhance the fastening, a reinforcing rib plate 153 is provided at the bending position.

[0084] In the implementation of this flexible intercepting mechanism, the circulation channel 151 is horizontally distributed in the valve body 15, and the chute 152 is longitudinally distributed in the valve body 15, that is, the circulation channel 151 and the chute 152 are perpendicular to each other, and in order to strengthen the tightness, a reinforcing rib plate 153 is provided at the vertical intersection of the circulation channel 151 and the chute 152. Of course, those skilled in the art can understand that the positional relationship between the circulation channel 151 and the chute 152 is not absolutely perpendicular to each other. In the equivalent replacement implementation, when the chute 152 has a certain deviation in the vertical direction relative to the circulation channel 151, or is directly inclined, it is equivalent to the expansion or contraction of the flexible sleeve 12. The moving area moves longitudinally or close to the longitudinal direction relative to the circulation channel 151 and does not occupy the lateral space. It can also be achieved that when it is applied to the diversion well, it does not need to be installed in the well in the horizontal direction, and has the characteristic of occupying very little space. Therefore, this structural position distribution relationship between the circulation channel 151 and the chute 152 is applicable in each embodiment of the present application and is also within the protection scope of the present invention.

[0085] Furthermore, in an embodiment of the flexible shut-off mechanism 10, in order to enable the flexible sleeve 12 to better drive the gate plate 14 to move during expansion or contraction, it also includes a pressure plate 16, which is fixed in the chamber 11 and located at the bottom of the chamber 11 to fit the top of the gate plate 14 and fixedly connected to the top of the gate plate 14, such as by bolts or screws.

[0086] As a working state of an embodiment of the present application, when the chamber 11 is filled with filler, the flexible sleeve 12 begins to expand until the bottom of the flexible sleeve 12 fits the bottom of the circulation channel 151 and seamlessly connects with the bottom of the circulation channel 151, thereby realizing the interception of the circulation channel 151.

[0087] As another working state of the embodiment of the present application, when the filling material is discharged from the chamber 11 , the flexible sleeve 12 begins to shrink until the bottom of the flexible sleeve 12 is located at the top of the circulation channel 151 , thereby achieving full conduction of the circulation channel 151 .

[0088] That is, in the embodiment of the present application, the expansion of the airbag is achieved by filling the chamber 11 inside the flexible sleeve 12 with fillers, or the contraction of the airbag is achieved by discharging the fillers from the chamber 11 inside the flexible sleeve 12. At the same time, the flexible sleeve 12 in the process of expansion or contraction can slide up and down in the slide groove 152, that is, when the flexible sleeve 12 is expanded, it slides downward from the slide groove 152 to the circulation channel 151, or drives the gate plate 14 to slide downward from the slide groove 152 to the circulation channel 151, and fits with the bottom of the circulation channel 151, thereby achieving flow interception; and when the flexible sleeve 12 is contracted, it slides upward from the circulation channel 151 to the slide groove 152, and when the flexible sleeve 12 slides upward to separate from the bottom of the circulation channel 151, or drives the gate plate 14 to slide upward to fit with the bottom of the circulation channel When the bottom of 151 is separated, the flow channel 151 is gradually connected; and such a structural design makes it unnecessary to put the flexible sleeve on the outside of the steel outer cover as in the prior art, nor does it require the flexible sleeve to wrap the entire steel outer cover, but only requires the flexible sleeve to slide in the slide groove of the valve body by expansion or contraction, which greatly reduces the fitting area between the flexible sleeve and the flow channel. When installing it in a diversion facility such as a diversion well, it only needs to be connected to any one of the pipe openings (water inlet pipe or water outlet pipe), and it does not need to be installed horizontally in the well, so it occupies very little space.

[0089] In addition, in the embodiment of the present application, the flexible intercepting mechanism 10 can be fixed to the pipe mouth of the sewage pipe in a flange-mounted manner through the valve body 15. The flexible intercepting mechanism 10 can also be fixed to the pipe mouth of the sewage pipe in a wall-mounted manner through the valve body 15, and the specific installation method of the flange-mounted or wall-mounted manner can be adopted in the prior art, which will not be described in detail in this embodiment.

[0090] Finally, it should be added that the filler in the embodiment of the present application can be gas (such as air, nitrogen, inert gas, etc.) or liquid (such as hydraulic oil, water, etc.). As a preference, the filler can be selected as gas, which can achieve the characteristics of rapid filling or rapid discharge, so that the flexible sleeve 12 can be expanded or contracted quickly, thereby achieving the technical effect of rapid interception or passage.

[0091] In the embodiments of the present specification, the entire sewage treatment unit can be a tank structure, and the first treatment area 20 and the second treatment area 40 are two independent areas of the tank structure (such as the first treatment area 20 on the left and the second treatment area 40 on the right). In the first treatment area 20, a plurality of partitions 70 can be provided to further divide the first treatment area 20 into a plurality of treatment sub-areas, and each partition 70 is provided with a water hole 60 for water to circulate between the plurality of treatment sub-areas through the water hole 60.

[0092] In this embodiment, the sewage treatment device includes a conducting pipe 50, which is arranged in the second treatment area 40; the conducting pipe 50 includes a first conducting port 501 and a second conducting port 502. The conducting pipe 50 is connected to the first treatment area 20 through the first conducting port 501; and the pipe mouth elevation of the first conducting port 501 is higher than the bottom elevation of the sewage pipe 30; the second conducting port 502 is located at the bottom of the second treatment area 40. It should be noted that in this embodiment, when water storage is required, the first valve is closed and the second valve is opened, and the flexible intercepting mechanism 10 is closed at the same time. As the liquid level of the water in the first treatment area continues to rise, when it just reaches the pipe mouth elevation of the first conducting port 501, the water in the first treatment area flows into the second treatment area 40 through the conducting pipe 50 under the action of gravity. Since the pipe mouth elevation of the first conducting port 501 is higher than the bottom elevation of the sewage pipe 30, there is no need to perform additional control on the conducting pipe 50 when the water in the first treatment area 20 is discharged normally. When the water level in the first treatment area reaches the height of the sewage pipe 30, it is directly discharged from the sewage pipe 30; and when it is necessary to discharge the water in the second treatment area, the first valve is opened and the second valve is closed, and the air source fills the second treatment area 40 with compressed gas to form air pressure in the second treatment area 40, thereby squeezing the water in the second treatment area 40 to flow into the first treatment area 20 through the conducting pipe 50, so as to achieve the technical effect of regulating and storing sewage when sewage discharge is not needed, and has the characteristics of simple structure, convenient operation and wide applicability.

[0093] For the conducting tube 50, it can be an "L"-shaped structure. Those skilled in the art can understand that the L-shaped structure is only one structural form of the conducting tube 50. In actual processes, simple deformations made according to actual conditions are also applicable to the present invention, such as an arc shape, or an arc shape at the corner of the L-shape, etc.

[0094] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
