Description

Technical Field

[0001] The invention belongs to the technical field of building water supply and drainage, and specifically relates to an energy-saving building water supply and drainage device and a working method thereof. Background Art

[0002] Building water supply and drainage is a general term for building water supply (connecting the tap water network to the indoor area to ensure living and production water supply) and drainage (providing discharge, drainage and filtration for the living, production and fire-fighting water generated by the building). For energy-saving building water supply and drainage devices, the domestic and production sewage generated during the drainage process will generally be filtered and treated, and returned to the flushing system of toilets and other places. This requires that the device be given an efficient and synchronous sewage treatment function, while also avoiding excessive waste of domestic water supply. The energy-saving building water supply and drainage devices in the existing technology generally perform physical treatment on the recycled sewage (gravity Sedimentation) and chemical treatment (flocculation and sedimentation), and the sewage tank used to receive sewage is not perfect enough. The source of some sewage from building drainage is unstable, with peak and off-peak periods. The amount of sewage is large during the peak period and small during the off-peak period. Therefore, the volume of the container for receiving sewage in the existing technology is fixed, which does not conform to the efficient concept of sewage treatment. The design of the sewage tank is mainly based on the overflow mode of fixed volume. When facing a small flow of sewage, the overflow speed is low, which is not conducive to the rapid recovery of sewage. When facing a large flow of sewage, it is overloaded and cannot be met. Therefore, it is urgent to design a new energy-saving building water supply and drainage device. Summary of the invention

[0005] As a preferred solution of the present invention, the sewage pipe 1 is installed on the left side of the sewage tank, and the sewage pipe 2 is installed on the right side of the sewage tank. The sewage pipe 1 is connected to the sedimentation chamber, and the sewage pipe 2 is connected to the precipitation chamber.

[0006] As a preferred solution of the present invention, the water inlet pipe and the drain pipe are respectively fixedly installed on the left and right sides of the top of the cover plate, a limiting ring is fixedly installed on the bottom of the inner wall of the water inlet pipe, the inner wall sealing sleeve of the water inlet pipe and the limiting ring is provided with a guide pipe, the outer surface of the guide pipe is movably sleeved with a spring 1, the two ends of the spring 1 are elastically connected to the limiting ring and the guide pipe respectively, and the bottom end of the guide pipe extends into the sedimentation chamber.

[0007] As a preferred solution of the present invention, the overflow pipe one and the overflow pipe two are both "U" shaped, the highest point of the overflow pipe two is higher than the highest point of the overflow pipe one, the left end axes of the overflow pipe one and the overflow pipe two are aligned front to back, and the right end axis of the overflow pipe two is located to the right of the right end axis of the overflow pipe one.

[0008] As a preferred solution of the present invention, a connecting groove is provided on the left side of the partition, and sealing grooves are provided around the partition. The internal sealing of the sealing groove is clamped with a rubber ring, the connecting groove is connected with the sealing groove, and the outer peripheral surface of the partition is respectively in contact with the bottom of the cover plate and the inner wall of the sedimentation chamber, and forms a seal with the cover plate and the inner wall of the sedimentation chamber through the rubber ring.

[0009] As a preferred solution of the present invention, the total volume value of the sedimentation chamber and the precipitation chamber is a fixed value, and the top of the rubber ring and the partition plate are both sealed and abutted against the bottom of the cover plate.

[0010] As a preferred solution of the present invention, the cover plate is fixedly connected to the other end of the telescopic column, the second spring is located in the inner cavity of the sealing cylinder, the two ends of the second spring are elastically connected to the sealing block and the sealing cylinder respectively, and the outer surface of the sealing cylinder is provided with multiple groups of through holes.

[0011] As a preferred solution of the present invention, the sealing cylinders are arranged in two groups and are symmetrically distributed on the front and rear sides of the inner wall of the sedimentation chamber. A protective block connected to the inner wall of the sedimentation chamber is fixedly installed on the outer side of the sedimentation chamber, and the radial cross-section of the protective block is an isosceles obtuse triangle.

[0012] A working method of an energy-saving building water supply and drainage device comprises the following steps:

[0013] S1. Close the sewage pipe 1 and sewage pipe 2, seal the bottom of the sedimentation chamber and the sedimentation chamber, connect the water inlet pipe to the drainage pipe, and connect the drainage pipe to the recovery pipe;

[0014] S2. The sewage in the drainage pipe flows into the sedimentation chamber through the water inlet pipe, and gradually raises the sewage liquid level in the sedimentation chamber for gravity sedimentation. Over time, gravity sedimentation removes turbid impurities in the sewage, and the liquid level begins to stratify up and down, and is clarified at the upper layer of the liquid surface;

[0015] S3. The clarified upper sewage overflows into the sedimentation chamber through the overflow hole, and the flocculant is put into the top opening of the feeding pipe, and is dispersed into the sedimentation chamber through the top of the support column and the outer surface of the dispersion block. The flocculant contacts the sewage and produces flocculation precipitation, which sinks to the bottom of the sedimentation chamber;

[0016] S4. When the liquid level in the limit ring is higher than the dispersion block, the dispersion block moves upward under the action of buoyancy and finally abuts against the cover plate, blocking the bottom opening of the feeding pipe, so that the sewage does not enter the feeding pipe, and the treated sewage that has been clarified by flocculation and sedimentation overflows along the drain pipe, completing the sewage recovery process;

[0017] S5. When there are a lot of impurities and flocculation sediments in the sedimentation chamber and the settling chamber, they can be discharged regularly by opening the sewage pipe 1 and sewage pipe 2;

[0018] S6. When the sewage discharge is at a low peak, the amount of sewage passing through the water inlet pipe and the diversion pipe is low and cannot fill them. At this time, the pressure on the partition comes from the sewage in the inner cavity of the sedimentation chamber, and the telescopic column, the telescopic column, and the sealing block are pushed to the right, and the spring 2 is compressed, so that the partition is connected between the two sets of overflow holes 1 to maintain the high water level in the sedimentation chamber;

[0019] S7. When sewage discharge is at its peak, the amount of sewage passing through the inlet pipe and the diversion pipe is high and completely fills them. At this time, the pressure on the partition comes from the sewage in the sedimentation chamber, the diversion pipe and the inner cavity of the inlet pipe. The depth of the sewage doubles, causing the partition to be continuously pushed to the right until the partition is completely located on the right side of the two sets of overflow holes.

[0020] S8. At this time, the volume of the sedimentation chamber becomes larger, and the volume of the precipitation chamber becomes smaller, and the treated sewage that has been clarified by flocculation and sedimentation is discharged quickly. The amount of sewage treated in the inner cavity of the sedimentation chamber doubles, and the sewage that has undergone preliminary gravity sedimentation overflows into the sedimentation chamber through overflow pipe 2 at a higher overflow height.

[0021] The beneficial effects of the present invention are as follows:

[0022] The device has been redesigned to improve the utilization efficiency of the device. The volume of the sedimentation chamber and the sedimentation chamber is dynamically changed by designing a freely movable partition. The movement of the partition is determined by the liquid level of the sewage in the sedimentation chamber. When the sewage rushes into the sedimentation chamber along the water inlet pipe and the diversion pipe, the liquid level at the left side of the partition increases, and the pressure on the left side of the partition increases, thereby pushing it to the right. The movement of the partition to the right will compress the spring 2 through the telescopic column and the sealing block to obtain the rebound force to move to the left. When the amount of sewage in the sedimentation chamber decreases, the elastic force of the spring 2 is greater than the water pressure on the partition, which can push the partition to return to the left to cope with the different treatment needs of sewage during peak and off-peak periods. By providing a sealing cylinder to accommodate the telescopic column, the sealing block and the spring 2, when the sewage enters the sedimentation chamber, the gradually increasing pressure of the sewage on the partition is converted into Spring 2 is compressed by the telescopic column, sealing block and partition to generate elastic potential energy. When the sewage discharge is at low peak, the inner cavity of the sedimentation chamber needs to reduce its capacity to ensure that the sewage treated by gravity sedimentation can overflow and be discharged as soon as possible. When the sewage discharge is at peak, the inner cavities of the water inlet pipe and the diversion pipe are full of sewage. At this time, the sewage pressure on the partition is doubled, and it has no time to overflow quickly along the overflow hole 1, so it can only continue to push the partition to the right. At this time, the volume of the sedimentation chamber increases and the liquid level of the sewage in the inner cavity of the sedimentation chamber is reduced in disguise. At the same time, the partition moves to the right to the right side of the overflow hole 1, and the overflow pipe 2 performs the overflow function. This design synchronously changes the volume of the sedimentation chamber by coordinating the sewage pressure sensed by the partition and the elastic potential energy of spring 2, and realizes the maximum efficient sewage treatment volume of the sedimentation chamber per unit time.

[0023] Note: In theory, the free movement of the baffle changes the volume of the inner cavity of the sedimentation chamber located on the left side of the baffle (i.e., the bottom area), thereby dynamically adapting to the sedimentation and settling degree of sewage with different flow rates. Moreover, the baffle does not stir the water in the sedimentation chamber when moving, so turbidity will not occur.

[0024] The device is also provided with a limit ring, a guide pipe and a spring, which are automatically adapted according to the flow rate of the sewage, so that when the amount of sewage is large, it is subjected to high water pressure and moves downward, so that the bottom of the guide pipe will be closer to the bottom of the sedimentation chamber. When the sewage discharge is at its peak, the sewage flow through the water inlet pipe and the guide pipe increases sharply, and a huge impact force is generated. The impact force of the sewage is converted into its own downward displacement by providing an outer edge at the top of the guide pipe, and the guide pipe can be automatically reset by compressing the spring. During the downward movement of the guide pipe, the sewage discharged by the guide pipe will be closer to the impurities settled at the bottom of the sedimentation chamber, thereby giving a thrust to the clarified sewage on the upper layer, avoiding the peak sewage from polluting the clarified treated sewage, and helping to improve the sewage treatment effect of the device.

[0025] The device has also made further optimization and improvement to the partition, by opening a sealing groove around the partition, and sealing and clamping the inside of the sealing groove, and then abutting against the inner wall of the cover plate and the sewage tank to provide a sealing function, and then opening a connecting groove connected to the sealing groove on the left side of the partition, the sewage entering the sedimentation chamber is introduced into the sealing groove. As the sewage liquid level in the sedimentation chamber rises, the pressure on the rubber ring begins to gradually increase, and is squeezed between the sealing groove and the sewage tank and the cover plate, providing a more reliable seal for the partition, and when the liquid level drops, the pressure on the rubber ring will decrease, so that the rubber ring cannot be in a state of long-term pressure, effectively extending the service life of the rubber ring.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 9 As shown, an embodiment of the present invention provides an energy-saving building water supply and drainage device, including a sewage tank 1, a sewage pipe 1 8 and a sewage pipe 2 9, a drainage hole 17 is opened on the right side of the top of the sewage tank, a cover plate 2 is pressed and installed on the top of the sewage tank 1, a water inlet pipe 3, a feeding pipe 6 and a drainage pipe 7 are fixedly installed on the top of the cover plate 2, a partition plate 27 is slidably installed on the inner cavity of the sewage tank 1, and the interior of the sewage tank 1 is divided into a sedimentation chamber 10 and a precipitation chamber 11 by the partition plate 27, a sealing cylinder 22 is fixedly installed inside the sedimentation chamber 11, and the internal sealing sleeve of the sealing cylinder 22 is connected with a telescopic column 24, a sealing block 25 and a spring 26, and the telescopic column 24, a sealing block 25 and a spring 26 are connected to the sealing cylinder 22. One end of the shrink column 24 is fixedly connected to the partition 27, and multiple groups of overflow pipes 1 4 and overflow pipes 2 5 located between the water inlet pipe 3 and the feeding pipe 6 are fixedly installed on the top of the sewage tank 1. Two groups of overflow holes 15 connected to the overflow pipe 1 4 are opened on the top of the sewage tank 1. Two groups of overflow holes 16 connected to the overflow pipe 2 5 are also opened on the top of the sewage tank 1. The two groups of overflow holes 15 and overflow holes 2 16 are respectively located on both sides of the partition 27. A mounting frame 18 is fixedly installed on the inner wall of the feeding pipe 6. A support column 19 is movably sleeved inside the mounting frame 18, and a dispersion block 20 is fixedly installed at the bottom of the support column 19;

[0038] The device has been redesigned to improve the utilization efficiency of the device. The volume of the sedimentation chamber and the sedimentation chamber is dynamically changed by designing a freely movable partition. The movement of the partition 27 is determined by the liquid level of the sewage in the sedimentation chamber 10. When the sewage rushes into the sedimentation chamber 10 along the water inlet pipe 3 and the guide pipe 13, the liquid level at the left side of the partition 27 increases, and the pressure on the left side of the partition 27 increases, thereby pushing it to move to the right. The movement of the partition 27 to the right will compress the spring 26 through the telescopic column 24 and the sealing block 25 to obtain a rebound force to move to the left. When the amount of sewage in the sedimentation chamber 10 decreases, the elastic force of the spring 26 is greater than the water pressure on the partition 27, which can push the partition 27 to return to the left to cope with the different treatment needs of sewage during peak and off-peak periods. By providing a sealing cylinder 22 to accommodate the telescopic column 24, the sealing block 25 and the spring 26, when the sewage enters the sedimentation chamber 10, the gradually increasing pressure of the sewage on the partition 27 The elastic potential energy generated by the compression of the spring 26 by the telescopic column 24, the sealing block 25 and the partition 27 is converted into the elastic potential energy. When the sewage discharge is at a low peak, the inner cavity of the sedimentation chamber 10 needs to reduce the capacity to ensure that the sewage treated by gravity sedimentation is discharged as soon as possible. When the sewage discharge is at a peak, the inner cavities of the water inlet pipe 3 and the guide pipe 13 are full of sewage. At this time, the sewage pressure on the partition 27 is doubled, and it is too late to quickly overflow along the overflow hole 15. The partition 27 can only be pushed to the right continuously. At this time, the volume of the sedimentation chamber 10 increases, and the liquid level of the sewage in the inner cavity of the sedimentation chamber 10 is reduced in disguise. At the same time, the partition 27 moves to the right to the right side of the overflow hole 15, and the overflow pipe 2 5 performs the overflow function. This design synchronously changes the volume of the sedimentation chamber 10 by coordinating the sewage pressure sensed by the partition 27 and the elastic potential energy of the spring 2 26, and realizes the sedimentation chamber 10 to achieve the maximum efficient sewage treatment volume per unit time.

[0039] Among them, the sewage pipe 1 8 is installed on the left side of the sewage tank 1, and the sewage pipe 2 9 is installed on the right side of the sewage tank 1. The sewage pipe 1 8 is connected to the sedimentation chamber 10, and the sewage pipe 2 9 is connected to the sedimentation chamber 11;

[0040] There are valves inside the sewage pipe 1 8 and the sewage pipe 2 9. The valves are usually closed. When more and more sediment and impurities are accumulated in the inner cavity of the sedimentation chamber 10 and the precipitation chamber 11, the valves of the sewage pipe 1 8 and the sewage pipe 2 9 are opened to discharge the impurities, sludge and sediment, thereby maintaining the space for the device to accumulate impurities.

[0041] Among them, the water inlet pipe 3 and the drainage pipe 7 are fixedly installed on the left and right sides of the top of the cover plate 2 respectively, and a limit ring 12 is fixedly installed on the bottom of the inner wall of the water inlet pipe 3. The inner wall sealing sleeve of the water inlet pipe 3 and the limit ring 12 is provided with a guide pipe 13, and the outer surface of the guide pipe 13 is movably sleeved with a spring 14, and the two ends of the spring 14 are elastically connected to the limit ring 12 and the guide pipe 13 respectively, and the bottom end of the guide pipe 13 extends into the sedimentation chamber 10;

[0042] The device is also designed with a limit ring 12, a guide tube 13 and a spring 14 to automatically adapt the downward displacement of the guide tube 13 according to the flow rate of the sewage, so that when the amount of sewage is large, it is subjected to a large water pressure and moves downward, so that the bottom of the guide tube 13 will be closer to the bottom of the sedimentation chamber 10. When the sewage discharge is at its peak, the sewage flow through the water inlet pipe 3 and the guide tube 13 increases sharply, and a huge impact force is generated. The impact force of the sewage is converted into its own downward displacement by providing an outer edge at the top of the guide tube 13, and the guide tube 13 can be automatically reset by compressing the spring 14. During the downward movement of the guide tube 13, the sewage discharged by it will be closer to the impurities settled at the bottom of the sedimentation chamber 10, thereby giving a thrust to the clarified sewage on the upper layer, avoiding the peak sewage from polluting the clarified treated sewage, and helping to improve the sewage treatment effect of the device.

[0043] Among them, the overflow pipe 1 4 and the overflow pipe 2 5 are both in a "U" shape, the highest point of the overflow pipe 2 5 is higher than the highest point of the overflow pipe 1 4, the left end axes of the overflow pipe 1 4 and the overflow pipe 2 5 are aligned front and back, and the right end axis of the overflow pipe 2 5 is located to the right of the right end axis of the overflow pipe 1 4;

[0044] Overflow pipe 1 4 and overflow pipe 2 5 are respectively adapted to the sewage discharge conditions during the off-peak period and the peak period:

[0045] During the off-peak period: the sewage in the water inlet pipe 3 and the guide pipe 13 cannot generate additional pressure on the partition 27. The partition 27 is supported by the telescopic column 24, the sealing block 25 and the spring 26 to maintain the position between the two groups of overflow holes 15, and the sewage in the sedimentation chamber 10 overflows quickly through the overflow hole 15;

[0046] During peak hours: sewage fills the water inlet pipe 3 and the guide pipe 13, and generates additional pressure on the partition 27, so that the partition 27 overcomes the elastic force from the spring 26 and moves rightward to the right side of the overflow hole 15, so that the volume of the sedimentation chamber 10 increases, thereby accommodating more sewage at the same time and improving the sewage treatment efficiency.

[0047] A connecting groove 28 is provided on the left side of the partition 27, and sealing grooves 29 are provided around the partition 27. A rubber ring 30 is sealed and clamped inside the sealing groove 29. The connecting groove 28 is connected to the sealing groove 29. The outer peripheral surface of the partition 27 abuts against the bottom of the cover plate 2 and the inner wall of the sedimentation chamber 10, and forms a seal with the cover plate 2 and the inner wall of the sedimentation chamber 10 through the rubber ring 30.

[0048] The device further optimizes and improves the partition 27 by opening a sealing groove 29 around the partition 27, sealing and clamping the sealing groove 29 inside, and then abutting against the inner wall of the cover plate 2 and the sewage tank 1 to provide a sealing function, and then opening a connecting groove 28 connected to the sealing groove 29 on the left side of the partition 27 to introduce the sewage entering the sedimentation chamber 10 into the sealing groove 29. As the sewage liquid level in the sedimentation chamber 10 rises, the pressure on the rubber ring 30 begins to gradually increase, and is squeezed between the sealing groove 29 and the sewage tank 1 and the cover plate 2, providing a more reliable seal for the partition 27. When the liquid level drops, the pressure on the rubber ring 30 will decrease, so that the rubber ring 30 cannot be in a state of long-term pressure, effectively extending the service life of the rubber ring 30.

[0049] The total volume of the sedimentation chamber 10 and the precipitation chamber 11 is a fixed value, and the top of the rubber ring 30 and the partition plate 27 are both sealed against the bottom of the cover plate 2;

[0050] The settling chamber 10 and the sedimentation chamber 11 are separated by a partition 27 and dynamically sealed. The volume change of the settling chamber 10 helps to automatically and reasonably adapt according to the sewage discharge volume, thereby improving the sewage treatment efficiency of the device.

[0051] The cover plate 2 is fixedly connected to the other end of the telescopic column 24, the second spring 26 is located in the inner cavity of the sealing cylinder 22, the two ends of the second spring 26 are elastically connected to the sealing block 25 and the sealing cylinder 22 respectively, and the outer surface of the sealing cylinder 22 is provided with multiple groups of through holes 23;

[0052] Spring 26 is responsible for converting the displacement generated by the partition 27 into elastic potential energy that changes with the change, so as to assist the partition 27 in automatically switching the overflow pipe 1 4 and the overflow pipe 2 5 for sewage discharge during high and low peak periods. The through hole 23 is used to generate negative pressure when the telescopic column 24 drives the sealing block 25 to move to the right, thereby assisting the sedimentation chamber 11 to absorb the sewage from the sedimentation chamber 10, thereby improving the efficiency of sewage overflow discharge.

[0053] The sealing cylinders 22 are arranged in two groups and are symmetrically distributed on the front and rear sides of the inner wall of the sedimentation chamber 11. A protective block 21 connected to the inner wall of the sedimentation chamber 11 is fixedly installed on the outer side of the sedimentation chamber 11. The radial cross section of the protective block 21 is an isosceles obtuse triangle.

[0054] The triangular design of the protection block 21 prevents flocculation sediment from remaining on its inclined surface, which helps the flocculation, sedimentation and clarification operation of sewage.

[0055] A working method of an energy-saving building water supply and drainage device comprises the following steps:

[0056] S1. Close the drain pipe 8, drain pipe 2 9, so that the sedimentation chamber 10, the bottom of the sedimentation chamber 11 is sealed, the inlet pipe 3 is connected to the drainage pipe, the drain pipe 7 is connected to the recovery pipe;

[0057] S2. The sewage in the drainage pipe flows into the sedimentation chamber 10 through the water inlet pipe 3, and gradually increases the sewage liquid level in the sedimentation chamber 10 for gravity sedimentation. Over time, gravity sedimentation removes turbid impurities in the sewage, and the liquid level begins to stratify up and down, and is clarified at the upper layer of the liquid surface;

[0058] S3. The clarified upper sewage overflows into the sedimentation chamber 11 through the overflow hole 15, and the flocculant is put into the top opening of the feeding pipe 6, and is dispersed through the top of the support column 19 and the outer surface of the dispersion block 20, and is dispersed into the sedimentation chamber 11. The flocculant contacts the sewage and produces flocculation precipitation, which sinks to the bottom of the sedimentation chamber 11;

[0059] S4. When the liquid level in the limit ring 12 is higher than the dispersion block 20, the dispersion block 20 moves upward under the action of buoyancy and finally abuts against the cover plate 2, blocking the bottom opening of the feeding pipe 6, so that the sewage does not enter the feeding pipe 6, and the treated sewage clarified by flocculation and sedimentation overflows along the drain pipe 7, completing the sewage recovery process;

[0060] S5. When there are many impurities and flocculation precipitation in the sedimentation chamber 10 and the sedimentation chamber 11, the sewage pipe 8 and the sewage pipe 9 can be opened and discharged regularly;

[0061] S6. When the sewage discharge is at a low peak, the amount of sewage passing through the water inlet pipe 3 and the guide pipe 13 is low and cannot fill them. At this time, the pressure on the partition 27 comes from the sewage located in the inner cavity of the sedimentation chamber 10, and pushes the telescopic column 24, the telescopic column 24, and the sealing block 25 to the right, compressing the spring 26, so that the partition 27 is connected between the two sets of overflow holes 15, maintaining the high water level in the sedimentation chamber 10;

[0062] S7. When the sewage discharge is at its peak, the amount of sewage passing through the water inlet pipe 3 and the guide pipe 13 is high and completely fills them. At this time, the pressure on the partition 27 comes from the sewage located in the sedimentation chamber 10, the guide pipe 13 and the inner cavity of the water inlet pipe 3. The depth of the sewage doubles, so that the partition 27 is continuously pushed to the right until the partition 27 is completely located on the right side of the two sets of overflow holes 15;

[0063] S8. At this time, the volume of the sedimentation chamber 10 becomes larger, the volume of the precipitation chamber 11 becomes smaller, and the treated sewage that has been clarified by flocculation and sedimentation is quickly discharged. The amount of sewage treated in the inner cavity of the sedimentation chamber 10 doubles, and the sewage that has undergone preliminary gravity sedimentation overflows to the sedimentation chamber 11 through the overflow pipe 25 at a higher overflow height.

6. The working method of an energy-saving building water supply and drainage device according to claim 5, characterized in that: The following steps are involved: S1. Close the sewage pipe 1 (8) and sewage pipe 2 (9), seal the bottom of the sedimentation chamber (10) and the sedimentation chamber (11), connect the water inlet pipe (3) to the drainage pipe, and connect the drainage pipe (7) to the recovery pipe; S2. The sewage in the drainage pipe flows into the sedimentation chamber (10) through the water inlet pipe (3), and gradually raises the sewage liquid level in the sedimentation chamber (10) for gravity sedimentation. Over time, gravity sedimentation removes turbid impurities in the sewage, and the liquid level begins to separate into upper and lower layers, and clarification is performed at the upper layer of the liquid level. S3. The clarified upper sewage overflows into the sedimentation chamber (11) through the overflow hole 1 (15), and the flocculant is put into the top opening of the feeding pipe (6), and is dispersed through the top of the support column (19) and the outer surface of the dispersion block (20), and then dispersed into the sedimentation chamber (11). The flocculant contacts the sewage and produces flocculation precipitation, which sinks to the bottom of the sedimentation chamber (11); S4. When the liquid level in the limit ring (12) is higher than the dispersion block (20), the dispersion block (20) moves upward under the action of buoyancy and finally abuts against the cover plate (2), thereby blocking the bottom opening of the feeding pipe (6) and preventing the sewage from entering the feeding pipe (6). The treated sewage clarified by flocculation and sedimentation overflows along the drain pipe (7), thereby completing the sewage recovery and treatment process; S5. When there are many impurities and flocculated sediments in the sedimentation chamber (10) and the sedimentation chamber (11), they can be discharged regularly by opening the sewage pipe 1 (8) and the sewage pipe 2 (9); S6. When the sewage discharge is at a low peak, the amount of sewage passing through the water inlet pipe (3) and the guide pipe (13) is low and cannot fill them. At this time, the pressure on the partition (27) comes from the sewage in the inner cavity of the sedimentation chamber (10), and pushes the telescopic column (24), the telescopic column (24), and the sealing block (25) to the right, compressing the spring 2 (26), so that the partition (27) is connected between the two sets of overflow holes 1 (15), maintaining the high water level in the sedimentation chamber (10); S7. When the sewage discharge is at its peak, the amount of sewage passing through the water inlet pipe (3) and the diversion pipe (13) is high and completely fills them. At this time, the pressure on the partition (27) comes from the sewage located in the sedimentation chamber (10), the diversion pipe (13) and the inner cavity of the water inlet pipe (3). The depth of the sewage doubles, causing the partition (27) to be continuously pushed to the right until the partition (27) is completely located on the right side of the two sets of overflow holes (15); S8. At this time, the volume of the sedimentation chamber (10) increases, the volume of the settling chamber (11) decreases, and the treated sewage that has been clarified by flocculation and sedimentation is quickly discharged. The amount of sewage treated in the inner cavity of the sedimentation chamber (10) doubles, and the sewage that has undergone preliminary gravity sedimentation overflows into the sedimentation chamber (11) through the overflow pipe 2 (5) at a higher overflow height.
