Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a green building and its sewage treatment system. Background Art

[0002] A green building refers to a high-quality building that can save resources, protect the environment, reduce pollution, provide people with healthy, applicable, and efficient living spaces, and maximize the harmonious coexistence between humans and nature during its service life. Green buildings focus on energy conservation, environmental protection, economy, and efficiency, and are an effective means to achieve sustainable development. Among them, sewage treatment is one of the important links. Sewage treatment is to separate the impurities from the water in the sewage. For example, domestic sewage, industrial wastewater, and agricultural sewage all need to be treated before discharge. There are many methods for sewage treatment, which can generally be divided into physical treatment, chemical treatment, and biological treatment. Physical treatment uses the method of static sedimentation. First, the sewage is allowed to stand still, and then the impurities in the sewage are separated from the water, and then discharged after meeting the sewage treatment standards.

[0003] However, the separation efficiency of traditional sewage treatment systems is relatively low, and when the sewage contains a large amount of sludge, the sewage treatment effect is poor. Summary of the Invention

[0004] Based on this, in view of the problems existing in the current traditional sewage treatment system with relatively low separation efficiency and poor sewage treatment effect, it is necessary to provide a sewage treatment system for green buildings.

[0005] The above object is achieved by the following technical solutions:

[0010] Expansion filter plates, there are several of the expansion filter plates, the expansion filter plates are arranged in the first chamber and the second chamber, several filter holes are formed in the expansion filter plates, the expansion direction of the expansion end of the expansion filter plates is consistent with the sliding direction of the moving plate, the expansion filter plates can move along the sliding direction of the moving plate to disengage from or enter the first chamber or the second chamber, when the expansion filter plates disengage from the first chamber or the second chamber, the first opening of the first chamber or the second opening of the second chamber is opened;

[0012] Further, the clamping component includes a first clamping block arranged on the expansion end of the expansion filter plate and a first clamping groove formed on the moving plate. When the first clamping block cooperates with the first clamping groove, the expansion filter plate is clamped with the moving plate so that the expansion end of the expansion filter plate can move synchronously with the moving plate. When the moving plate moves to a preset position, the first clamping block disengages from the first clamping groove so that the expansion end of the expansion filter plate disengages from the moving plate.

[0013] Further, vertical grooves are formed at positions corresponding to the expansion ends of the expansion filter plates on both side surfaces of the moving plate. When the expansion end of the expansion filter plate is connected to the moving plate, the expansion end of the expansion filter plate is located in the vertical groove.

[0014] Further, a first driving component is further included. The first driving component includes a synchronous plate, a first hydraulic cylinder and an elastic member. The synchronous plate connects the fixed ends of several expansion filter plates. One end of the elastic member is connected inside the machine shell, and the other end of the elastic member is connected to the synchronous plate. The fixed end of the first hydraulic cylinder is arranged inside the machine shell, and the extending direction of the extending end of the first hydraulic cylinder points to the synchronous plate;

[0015] Initially, the elastic member is in a stretched state, the elastic member can drive the expansion filter plate to move away from the moving plate, and the telescopic end of the first hydraulic cylinder can abut against the synchronous plate to drive the expansion filter plate to move closer to the moving plate.

[0016] Further, the inclination directions of the bottoms of the first chamber and the second chamber are opposite. The bottoms of the first chamber and the second chamber are both telescopic bottom plates. The telescopic ends of the two telescopic bottom plates are fixedly connected to both side surfaces of the moving plate. The telescopic end of the telescopic baffle is telescoped by a second driving component;

[0017] On the side of the telescopic bottom plate with a higher position in the first chamber, a first sieve hole is provided, and the first sieve hole is located below the telescopic bottom plate; on the side of the telescopic bottom plate with a higher position in the second chamber, a second sieve hole is provided, and the second sieve hole is located below the telescopic bottom plate;

[0018] On the outside of the first sieve hole and the outside of the second sieve hole, telescopic baffles are provided, and sludge discharge outlets are provided below the two telescopic baffles. The two telescopic baffles are horizontally arranged to block the sludge discharge outlets;

[0019] Initially, the telescopic ends of the telescopic baffles extend, and the sewage in the first chamber flows through the telescopic baffles and is discharged through the second sieve hole, and the sewage in the second chamber flows through the telescopic baffles and is discharged through the first sieve hole;

[0020] When the moving plate moves to a preset position in the first chamber or the second chamber, the telescopic ends of the telescopic baffles shorten, the sludge discharge outlets are opened, and the sludge in the first chamber or the second chamber falls into the sludge discharge outlets.

[0022] On the telescopic baffle, a second clamping assembly is provided. The second clamping assembly includes a second clamping block and a second clamping groove. The second clamping block is arranged on the telescopic end of the telescopic baffle, the second clamping groove is opened on the fixed end of the telescopic baffle, and a tension spring is arranged inside the telescopic baffle;

[0023] After the telescopic end of the telescopic baffle extends under the action of the second hydraulic cylinder against the tension of the tension spring, the second clamping block and the second clamping groove cooperate to limit the retraction of the telescopic end of the telescopic baffle.

[0024] Further, on the lower end of the telescopic bottom plate, and on the telescopic end of the telescopic bottom plate, a convex block is provided. The convex block moves synchronously with the telescopic end of the telescopic bottom plate. When the moving plate moves to the preset position, the convex block contacts the second clamping block, so that the second clamping block is disengaged from the second clamping groove, and the telescopic end of the telescopic baffle retracts.

[0025] Further, a third driving assembly is further included. The third driving assembly can drive the moving plate to slide. The third driving assembly includes a driving motor and a rack. The rack is fixedly arranged on the moving plate, and the gear of the driving motor meshes with the rack, and the driving motor drives the moving plate to move.

[0026] Further, it further includes a bracket, the bracket is arranged at the bottom of the casing, and the bracket can support the casing.

[0027] A green building includes a sewage treatment system for a green building.

[0028] The beneficial effects of the present invention are:

[0029] The present invention provides a green building and its sewage treatment system, wherein the sewage treatment system includes a casing, a moving plate is slidably arranged in the casing, the moving plate divides the casing into a first chamber and a second chamber, and when the moving plate moves in the casing, it can change the volumes of the first chamber and the second chamber. A plurality of telescopic filter plates are arranged in both the first chamber and the second chamber, and a first clamping component is arranged between the telescopic filter plates and the moving plate. The first clamping component connects one end of the telescopic filter plate to the moving plate. Through the reciprocating movement of the moving plate, the volume of the first chamber or the second chamber becomes smaller, thereby squeezing the sludge and further separating the sewage in the sludge, improving the sewage treatment effect. The sewage treatment efficiency is also improved by the setting of the alternating operation of the two chambers.

[0030] In the present invention, a vertical groove is opened on the moving plate, and when the telescopic filter plate is connected to the moving plate, it is located in the vertical groove, so that when the telescopic filter plate squeezes the sludge, both ends of the telescopic filter plate are evenly stressed, improving stability.

[0031] In the present invention, by setting the inclination directions of the inner bottom plates of the first chamber and the second chamber to be opposite, the discharge directions of the sludge and sewage in the first chamber and the second chamber are opposite, improving the discharge efficiency of the sewage and sludge and avoiding blockage.

[0051] Refer to Figures 1 - 10 to describe a sewage treatment system for a green building provided by an embodiment of the present application.

[0052] A sewage treatment system for a green building is used to treat sewage, including a housing 100. An accommodation tank is arranged inside the housing 100. The accommodation tank is open at the top and inclined at the bottom. A moving plate 400 is slidably arranged inside the accommodation tank. The moving plate 400 divides the accommodation tank into a first chamber and a second chamber. A first water inlet 101 is opened at a position on the housing 100 corresponding to the first chamber, and a second water inlet 102 is opened at a position on the housing 100 corresponding to the second chamber. Sewage enters the first chamber and the second chamber through the first water inlet 101 and the second water inlet 102. A number of telescopic filter plates 300 are arranged in both the first chamber and the second chamber. A number of filter holes are opened on the telescopic filter plates 300. The filter holes can only allow sewage to pass through and cannot allow sludge to pass through. A number of telescopic filter plates 300 are slidably inserted into the first chamber and the second chamber, further dividing the first chamber and the second chamber into multiple chambers. A first opening is opened on the side surface of the first chamber that contacts the lower end of the inclined bottom, that is, one of the telescopic filter plates 300 among the multiple telescopic filter plates 300 forms this side surface. When the telescopic filter plate 300 is separated from the first chamber, one side surface of the first chamber is opened to form the first opening; the second opening of the second chamber is the same as the first opening of the first chamber and will not be elaborated further. Sewage enters each chamber through the first water inlet 101 and the second water inlet 102. Since the bottom of the accommodation tank is inclined, the sewage in each chamber is discharged through the filter holes on the telescopic filter plates 300, while the sludge stays in each chamber. The telescopic filter plate 300 is separated from the first chamber or the second chamber to open the first opening of the first chamber or the second opening of the second chamber to discharge the sludge.

[0053] A first clamping component 301 is arranged between the telescopic end of the telescopic filter plate 300 and the moving plate 400. The first clamping component 301 clamps the telescopic end of the telescopic filter plate 300 and the moving plate 400 together. When the moving plate 400 slides, it can drive the telescopic end of the telescopic filter plate 300 to expand and contract. When the moving plate 400 moves inside the accommodation tank, it can change the volume in the first chamber and the second chamber to squeeze the sludge, squeezing out the sewage in the sludge and improving the separation effect of sludge and sewage in the sewage.

[0054] Specifically, such as Figure 5 and Figure 9As shown, the first clamping component 301 includes a first clamping block 307 provided at the telescopic end of the telescopic filter plate 300 and a first clamping groove 308 provided on the moving plate 400. A clamping groove is formed at a position on the upper end surface of the telescopic end of the telescopic filter plate 300 away from the fixed end. The first clamping block 307 is located in the clamping groove and can slide in the clamping groove in a guiding manner. A compression spring (not shown in the figure) is provided at the bottom of the first clamping block 307, and the compression spring causes a part of the first clamping block 307 to protrude from the clamping groove. The first clamping groove 308 is formed at a position on the moving plate 400 corresponding to the first clamping block 307 at the telescopic end of the telescopic filter plate 300. The first clamping block 307 can be inserted into the first clamping groove 308, and a closed rectangular groove is formed above the first clamping groove 308. Two protrusions are fixedly provided on the upper surface of the first clamping block 307. The side surfaces of the two protrusions away from each other are inclined surfaces, and the side surfaces close to each other are vertical surfaces. One end of the first clamping block 307 is inserted into the first clamping groove 308, and the inclined surface of the protrusion is in sliding contact with the first clamping groove 308, causing the first clamping block 307 to move downward. When the protrusion is located in the closed rectangular groove on the first clamping groove 308, the first clamping block 307 moves upward under the action of the compression spring, and the vertical surface of the protrusion of the first clamping block 307 contacts one end of the rectangular groove for limiting, thereby connecting the telescopic end of the telescopic filter plate 300 to the moving plate 400; when the inclined surface of another protrusion on the first clamping block 307 is in sliding contact with the fixed end of the telescopic filter plate 300, the first clamping block 307 moves downward, and the protrusion of the first clamping block 307 located in the rectangular groove on the first clamping groove 308 disengages, thereby disconnecting the telescopic end of the telescopic filter plate 300 from the moving plate 400.

[0055] Initially, the moving plate 400 is located in the middle of the accommodating box. The volumes of the first chamber and the second chamber are the same. One end of the first clamping block 307 is inserted into the first clamping groove 308 so that the telescopic end of the telescopic filter plate 300 is connected to the moving plate 400. When the moving plate 400 moves, it can drive the telescopic end of the telescopic filter plate 300 to expand and contract, that is, the volume of the chamber between every two adjacent telescopic filter plates 300 changes. When the moving plate 400 moves towards the first chamber, the volume of the first chamber becomes smaller, and the volume of the second chamber becomes larger. The sludge in the first chamber is squeezed, further separating the sludge from the sewage. When the moving plate 400 moves to the preset position (the preset position is that the telescopic end of the telescopic filter plate 300 is all located within the fixed end), it stops moving. The first clamping block 307 is pressed into the card slot by the fixed end of the telescopic filter plate 300, causing the first clamping block 307 to disengage from the first clamping groove 308. The telescopic filter plate 300 moves away from the moving plate 400 in the direction driven by the first driving assembly to leave the first chamber, opening the opening in the first chamber. Since the bottom surface of the first chamber is inclined and the telescopic filter plate 300 leaves the first chamber, the sludge is no longer blocked by the telescopic filter plate 300 and is discharged from the first chamber under the action of gravity. After the sludge is discharged, the telescopic filter plate 300 enters the first chamber again under the action of the first driving assembly. The first clamping block 307 on the telescopic filter plate 300 cooperates with the first clamping groove 308 to reconnect the telescopic end of the telescopic filter plate 300 to the moving plate 400. The moving plate 400 drives the telescopic end of the telescopic filter plate 300 to move towards the second chamber to reset. At this time, the sewage treatment in the first chamber is completed; the moving plate 400 moves towards the second chamber to start squeezing the sludge in the second chamber. This process is the same as that of the first chamber and will not be elaborated here.

[0056] Specifically, such as Figure 4 and Figure 5As shown in the figure, the first driving component includes a synchronous plate 302, a first hydraulic cylinder 103, and an elastic member 200. The fixed ends of all the telescopic filter plates 300 in the first chamber or the second chamber are connected to the side surface of the synchronous plate 302, so that the telescopic filter plates 300 can move synchronously. One end of the elastic member 200 is fixedly arranged in the housing 100, and the other end of the elastic member 200 is connected to the other side surface of the synchronous plate 302. Initially, the elastic member 200 is in a stretched state. When the moving plate 400 moves to a preset position, the first clamping block 307 and the first clamping groove 308 are disengaged. Under the pulling force of the elastic member 200, the synchronous plate 302 moves away from the moving plate 400 to disengage from the first chamber. The fixed end of the first hydraulic cylinder 103 is fixedly arranged in the housing 100, and the extending direction of the extending end of the first hydraulic cylinder 103 points to the moving plate 400. Initially, the extending end of the first hydraulic cylinder 103 retracts. When the synchronous plate 302 drives the telescopic filter plates 300 to disengage from the first chamber or the second chamber and the sludge is discharged, the extending end of the first hydraulic cylinder 103 extends and abuts against the synchronous plate 302, and then drives the synchronous plate 302 to move towards the moving plate 400 to reset.

[0057] Through the sliding setting of the moving plate 400 and the setting of the telescopic filter plates 300, the volumes of the first chamber and the second chamber can change. When the sewage stands in the first chamber and the second chamber for a period of time, the sludge in the sewage is separated from the sewage. Then, by moving the moving plate 400, the volume of the first chamber or the second chamber becomes smaller, thereby squeezing the sludge, and further separating the sewage in the sludge, improving the sewage treatment effect. The sewage treatment efficiency is also improved by the alternating operation of the two chambers.

[0058] In a further embodiment, a plurality of vertical grooves 303 are formed on the moving plate 400. When the telescopic end of the telescopic filter plate 300 enters the vertical grooves 303, the first clamping block 307 on the telescopic filter plate 300 cooperates with the first clamping groove 308. Through the cooperation of the first clamping block 307 and the first clamping groove 308, one end of the telescopic filter plate 300 is clamped in the vertical grooves 303. The setting of the vertical grooves 303 enables the telescopic end of the telescopic filter plate 300 to be reliably connected to the moving plate 400, so that when the volume of the first chamber or the second chamber becomes smaller to squeeze the sludge, both ends of the telescopic filter plate 300 can be evenly stressed, thereby improving the stability of the sewage treatment system of the green building during operation.

[0059] In a further embodiment, the bottom plates in both the first chamber and the second chamber are telescopic bottom plates. For the convenience of description, the telescopic bottom plate in the first chamber is named the first telescopic bottom plate 304, and the telescopic bottom plate in the second chamber is named the second telescopic bottom plate 305. The tilting directions of the first telescopic bottom plate 304 and the second telescopic bottom plate 305 are opposite, so that the discharging directions of the sewage and sludge in the first chamber are opposite to those in the second chamber, thereby separating the sewage outlets of the first chamber and the second chamber and avoiding the blockage phenomenon caused by the two chambers sharing a sewage outlet.

[0060] Specifically, the telescopic ends of the first telescopic bottom plate 304 and the second telescopic bottom plate 305 are respectively connected to both side surfaces of the moving plate 400. When the moving plate 400 moves, the telescopic ends of the first telescopic bottom plate 304 and the second telescopic bottom plate 305 move synchronously with the moving plate 400. That is, when the moving plate 400 moves towards the direction close to the first chamber, the telescopic end of the first telescopic bottom plate 304 retracts, and the telescopic end of the second telescopic bottom plate 305 extends. The higher end of the first telescopic bottom plate 304 is connected to one side surface of the first chamber. A number of first sieve holes 309 are provided on this side surface. The first sieve holes 309 are used to discharge the sewage in the second chamber. The first sieve holes 309 are located below the position where this side surface is connected to the first telescopic bottom plate 304. A telescopic baffle 500 is provided outside this side surface. The telescopic baffle 500 is horizontally arranged, that is, the telescopic baffle 500 is perpendicular to this side surface. The fixed end of the telescopic baffle 500 is located below the first sieve holes 309, and the telescopic end of the telescopic baffle 500 is located below the second opening of the second chamber; the higher end of the second telescopic bottom plate 305 is connected to one side surface of the second chamber. A second sieve hole 310 is provided on this side surface. The second sieve hole 310 is used to discharge the sewage in the first chamber. The second sieve holes 310 are all located below the position where this side surface is connected to the second telescopic bottom plate 305. A telescopic baffle 500 is also provided outside this side surface. The telescopic baffle 500 is horizontally arranged, that is, the telescopic baffle 500 is perpendicular to this side surface. The fixed end of the telescopic baffle 500 is located below the second sieve holes 310, and the telescopic end of the telescopic baffle 500 is located below the first opening of the first chamber.

[0061] A sludge discharge port 107 is provided below the telescopic baffle 500. Initially, the telescopic end of the telescopic baffle 500 extends. A tension spring (not shown in the figure) is provided inside the telescopic baffle 500. The tension spring makes the telescopic end of the telescopic baffle 500 tend to move towards the fixed end. The telescopic end of the telescopic baffle 500 is kept in the extended state through the second clamping assembly to block the sludge discharge port 107, thereby preventing sewage from flowing out through the sludge discharge port 107. When the moving plate 400 moves to a preset position, the second clamping assembly no longer restricts the telescopic end of the telescopic baffle 500. The telescopic end of the telescopic baffle 500 retracts under the action of the tension spring, so that the sludge discharge port 107 is opened, and the sludge in the first chamber or the second chamber is discharged from the machine housing 100 under the action of gravity through the sludge discharge port 107.

[0062] Specifically, the second clamping assembly includes a second clamping block 501 provided at the telescopic end of the telescopic baffle 500 and a second clamping groove 502 opened at the fixed end of the telescopic baffle 500. The second clamping block 501 is guidingly arranged on the telescopic end of the telescopic baffle 500. A compression spring (not shown in the figure) is provided below the second clamping block 501. The upper part of the second clamping block 501 is a wedge block. When the telescopic end of the telescopic baffle 500 retracts into the fixed end, the second clamping block 501 retracts into the telescopic end of the telescopic baffle 500. When the telescopic end of the telescopic baffle 500 extends to the limit position (the limit position refers to the longest position where the telescopic end extends), the second clamping block 501 extends out of the telescopic end of the telescopic baffle 500 and is located in the second clamping groove 502 to restrict the telescopic movement of the telescopic end. That is, when the telescopic end of the telescopic baffle 500 is at the limit position, the tension spring inside the telescopic baffle 500 is in a stretched state. At this time, under the action of the second clamping block 501 and the second clamping groove 502, the telescopic end of the telescopic baffle 500 is kept in the extended state. When the second clamping block 501 and the second clamping groove 502 are disengaged, the telescopic end of the telescopic baffle 500 shortens under the action of the tension spring.

[0063] It should be noted that when the moving plate 400 does not move to the preset position, the sewage in the first chamber flows through the filter holes on the telescopic filter plate 300, flows through the upper surface of the telescopic baffle 500, and is discharged into the water outlet 108 through the second sieve holes 310; the sewage in the second chamber flows through the filter holes on the telescopic filter plate 300, flows through the upper surface of the telescopic baffle 500, and is discharged into the water outlet 108 through the first sieve holes 309; when the moving plate 400 moves to the preset position, the telescopic end of the telescopic baffle 500 retracts to open the sludge discharge port 107, so that the sludge in the first chamber or the second chamber is discharged into the sludge discharge port 107. After the sludge is discharged, the telescopic end of the telescopic baffle 500 extends under the action of the second driving assembly to reset.

[0064] Specifically, the second driving component includes a second hydraulic cylinder 104. The fixed end of the second hydraulic cylinder 104 is fixedly arranged inside the machine housing 100, and the extending end of the second hydraulic cylinder 104 is connected to the telescopic end of the telescopic baffle 500. Initially, the extending end of the second hydraulic cylinder 104 shortens, and the telescopic end of the telescopic baffle 500 extends. When the telescopic end of the telescopic baffle 500 shortens under the action of the tension spring, the extending end of the second hydraulic cylinder 104 extends. After the sludge in the first chamber or the second chamber is discharged, the shortening of the extending end of the second hydraulic cylinder 104 drives the telescopic end of the telescopic baffle 500 to extend so that the second engaging block 501 and the second engaging groove 502 cooperate, thereby keeping the telescopic end of the telescopic baffle 500 in an extended state to block the sludge discharge port 107.

[0065] Specifically, in order to enable the second engaging block 501 to disengage from the second engaging groove 502 when the moving plate 400 moves to a preset position, a convex block 306 is arranged at the lower end of the telescopic bottom plate and on the telescopic end of the telescopic bottom plate. The convex block 306 moves synchronously with the telescopic end of the telescopic bottom plate. When the moving plate 400 moves to the preset position, the convex block 306 can contact the second engaging block 501 on the telescopic end of the telescopic baffle 500. Since the upper part of the second engaging block 501 is a wedge-shaped block, the sliding contact between the convex block 306 and the inclined surface of the wedge-shaped block causes the second engaging block 501 to move downward, and the second engaging block 501 disengages from the second engaging groove 502 on the telescopic baffle 500 and no longer restricts the telescopic end of the telescopic baffle 500. The telescopic end of the telescopic baffle 500 shortens under the action of the tension spring, opening the sludge discharge port 107, and the sludge in the first chamber or the second chamber falls into the sludge discharge port 107.

[0066] Specifically, in order to enable the moving plate 400 to slide in the receiving box, the sewage treatment system of the green building further includes a third driving component. The third driving component includes a driving motor 106 and a rack 401. The rack 401 is fixedly arranged on the moving plate 400, the driving motor 106 is fixedly arranged on the machine housing 100, and the gear of the driving motor 106 meshes with the rack 401. The driving motor 106 drives the rack 401 to move, thereby driving the moving plate 400 to move in the receiving box. The reciprocating movement of the moving plate 400 causes the volumes of the first chamber and the second chamber to change repeatedly, thereby squeezing the sludge in the first chamber and the second chamber.

[0067] In a further embodiment, the sewage treatment system of the green building further includes a bracket 105. The bracket 105 is arranged at the bottom of the machine housing 100. The bracket 105 can support the machine housing 100 so that the sewage treatment system of the green building can work stably, improving the stability of the sewage treatment system of the green building.

[0068] Combined with the above embodiments, the specific working process of the sewage treatment system of the green building provided by an embodiment of the present application is described as follows:

[0069] Initial state:

[0070] The moving plate 400 is located in the middle of the accommodating box. The volumes of the first chamber and the second chamber are the same. The first clamping block 307 is located in the first clamping groove 308 to connect the telescopic end of the telescopic filter plate 300 to the moving plate 400. The second clamping block 501 is located in the second clamping groove 502 to make the telescopic end of the telescopic baffle 500 located at the limit position to block the sludge discharge port 107.

[0071] Start working:

[0072] Sewage containing a large amount of sludge is introduced into the first water inlet 101 and the second water inlet 102. The sewage enters the first chamber through the first water inlet 101, and the sewage enters the second chamber through the second water inlet 102.

[0073] Sewage containing a large amount of sludge enters the first chamber and the second chamber through the first water inlet 101 and the second water inlet 102. The sewage is discharged through the filter holes of the telescopic filter plate 300 in the first chamber and the second chamber. Specifically, the sewage in the first chamber passes through the upper surface of the telescopic baffle 500 and then is discharged into the water outlet 108 through the second sieve hole 310. The sewage in the second chamber passes through the upper surface of the telescopic baffle 500 and then is discharged into the water outlet 108 through the first sieve hole 309. After a period of time, a large amount of sludge accumulates in the first chamber or the second chamber and is not discharged.

[0074] Sewage discharge from the first chamber:

[0075] Starting the drive motor 106 causes the moving plate 400 to move in the direction close to the first chamber. During the movement of the moving plate 400, the telescopic end of the telescopic filter plate 300 in the first chamber synchronously shortens as the moving plate 400 moves, reducing the volume of the first chamber and thus squeezing the sludge in the first chamber. The sewage generated after the sludge is squeezed passes through the filter holes on the telescopic filter plate 300. Since the bottom of the first chamber is inclined, the sewage flows through the upper surface of the telescopic baffle 500 under the action of gravity and then is discharged into the water outlet 108 through the second sieve holes 310. All the water in the first chamber is discharged from the water outlet 108 out of the housing 100. As the moving plate 400 continues to move in the direction close to the first chamber, when the moving plate 400 moves to a preset position, the first clamping block 307 on the telescopic filter plate 300 disengages from the first clamping groove 308 on the moving plate 400. After the disengagement, the synchronous plate 302 drives the telescopic filter plate 300 to move away from the moving plate 400 under the action of the elastic member 200 until the telescopic filter plate 300 completely leaves the first chamber, so that the sludge in the first chamber is no longer blocked by the telescopic filter plate 300. At the same time, the convex block 306 contacts the second clamping block 501 on the telescopic end of the telescopic baffle 500, causing the second clamping block 501 to disengage from the second clamping groove 502. After the disengagement, the telescopic end of the telescopic baffle 500 shortens under the action of the tension spring to open the sludge discharge port 107. Since the bottom of the first chamber is inclined and the squeezed sludge is not blocked by the telescopic filter plate 300, the sludge is discharged from the sludge discharge port 107 under the action of gravity. After the sludge is discharged, the extending end of the first hydraulic cylinder 103 extends to drive the synchronous plate 302 to move in the direction close to the moving plate 400 until one end of the telescopic filter plate 300 on the moving plate 400 is clamped with the moving plate 400 and then stops. The extending end of the second hydraulic cylinder 104 shortens, so that the telescopic end of the telescopic baffle 500 extends. After extending to the limit position, the second clamping block 501 and the second clamping groove 502 cooperate so that the telescopic end of the telescopic baffle 500 does not retract under the action of the tension spring. Thereafter, the moving plate 400 drives the telescopic filter plate 300 to move in the direction close to the second chamber.

[0076] Sewage discharge from the second chamber:

[0077] After the moving plate 400 is reset, the moving plate 400 moves in the direction close to the second chamber. The treatment process of the sewage and sludge in the second chamber is the same as that of the sewage and sludge in the first chamber, so it will not be elaborated here.

[0078] In another embodiment of the present invention, a green building is provided, and the green building includes the sewage treatment system of the above-mentioned green building. The green building using this sewage treatment system can effectively treat domestic sewage, making the sewage meet the discharge requirements after treatment and being environmentally friendly.

[0079] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope described in this specification.

[0080] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
