Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and in particular to a wastewater treatment device. Background Technology

[0002] In the petrochemical industry, conventional wastewater treatment equipment includes a regulating unit, an oil removal unit, a biochemical unit, and an ozone oxidation unit. These units are basically constructed using reinforced concrete structures to build the outer shell of the equipment. Due to this construction method, various units can only be constructed on-site, resulting in a significant time commitment when building the wastewater treatment system. Summary of the Invention

[0003] In order to shorten the time required to build a wastewater treatment system, this application provides a wastewater treatment device.

[0004] This application provides a wastewater treatment equipment with the following technical solution:

[0005] A wastewater treatment plant includes, in sequence, a regulating tank, a rapid oil separator, a high-efficiency circular flotation unit, a biological fluidized bed, a multi-effect sedimentation reactor, an ozone fluidized bed, a buffer tank, a homogenizing filter, and a product water tank. The outer shell of each unit is made of steel.

[0006] Wastewater enters the regulating tank, and the outlet of each device is connected to the inlet of the next device. The outlet of the product water tank is connected to the inlet of the water reuse system.

[0007] Wastewater treatment equipment also includes a wastewater tank, the outer shell of which is also made of steel. The wastewater outlet of the homogenizing filter is connected to the inlet of the wastewater tank, and the outlet of the wastewater tank is connected to the inlet of the multi-effect sedimentation reactor.

[0008] By adopting the above technical solution, since the shells of each device are made of steel, each device can be manufactured in the factory, then transported to the installation site for installation, and finally connected to adjacent devices by pipelines, realizing the modular installation of the sewage treatment system. There is no need to use steel bars and concrete to pour the shells of each device on site, avoiding the situation where the shells of each device need to be poured sequentially when using the pouring method. This allows operators to choose the installation order of each device as needed, shortens the time required to build the sewage treatment system, and makes the construction of the sewage treatment system more flexible.

[0009] Optionally, the wastewater tank is located above the product water tank, and the homogenizing filter is located above the wastewater tank.

[0010] By adopting the above technical solutions, the footprint of the sewage treatment system is reduced, and the cost of the sewage treatment system is saved.

[0011] Optionally, the inlet end of the wastewater pool is higher than the outlet end, and the inlet end and outlet end are distributed on both sides of the wastewater pool. A rectangular discharge hopper is fixedly connected to one side of the wastewater pool. The discharge hopper is higher than the outlet end of the wastewater pool and higher than the water surface in the wastewater pool. The length direction of the discharge hopper is set along the width direction of the wastewater pool, and the size of the discharge hopper gradually decreases in the direction away from the wastewater pool.

[0012] The bottom of the wastewater tank is slidably connected to a filter plate that slides along its height direction. The filter plate is lower than the discharge hopper. The wastewater tank is also equipped with a drive assembly that drives the filter plate to move upward and rotate. The rotation of the filter plate causes the impurities above it to slide into the discharge hopper.

[0013] By adopting the above technical solution, in the initial state, the drive assembly positions the filter plate at the bottom of the wastewater tank, and the filter plate is horizontal, higher than the outlet end of the wastewater tank. At this time, the filter plate filters the wastewater flowing into the wastewater tank, and the impurities in the wastewater remain above the filter plate, reducing the impurity content in the wastewater flowing into the multi-effect sedimentation reactor. To prevent impurities from clogging the filter plate, after a period of time, the operator controls the drive assembly to move the filter plate upward until it floats above the wastewater, and the filter plate moves to the discharge hopper. During this process, the drive assembly also rotates the filter plate, and the side of the filter plate away from the discharge hopper tilts upward, allowing the impurities on the filter plate to slide into the discharge hopper and be discharged from the wastewater tank. After the filter plate has tilted for a period of time, the operator controls the drive assembly to move the filter plate back to its original position.

[0014] Optionally, the drive assembly includes a ring frame slidably connected in the wastewater tank, the filter plate is hinged to the upper surface of the ring frame on the side near the discharge hopper, the filter plate overlaps the ring frame, the sliding direction of the ring frame is set along the height direction of the wastewater tank, and a plurality of support springs are fixedly connected to the ring frame, the lower end of the support springs is fixed to the inner bottom wall of the wastewater tank.

[0015] A crossbar is provided below the ring frame. The crossbar is slidably connected to the wastewater tank. The sliding direction of the crossbar is set along the length of the wastewater tank, and the sliding trajectory of the crossbar gradually tilts upward along the direction close to the discharge hopper. A telescopic rod with a retractable length is connected to the crossbar, and the telescopic rod is located in the ring frame.

[0016] The filter plate is slidably connected with protrusions that correspond one-to-one with the telescopic rods. The sliding direction of the protrusions is set along the length of the wastewater pool. The length of the sliding trajectory of the protrusions is less than the length of the filter plate. A limiting spring is fixedly connected to the protrusions, and the telescopic direction is set along the length of the wastewater pool. The limiting spring is fixed to the filter plate. A pull rod is hinged to the protrusions. The limiting spring causes the end of the pull rod near the protrusions to tilt away from the telescopic rods, and the end of the pull rod away from the protrusions to tilt upwards and be hinged to the telescopic end of the telescopic rods.

[0017] The drive assembly also includes a drive component that drives the telescopic rod to reciprocate along the length of the wastewater pool.

[0018] By adopting the above technical solution, in the initial state, the driving component works, causing the crossbar to be located at the lower end of the mating groove. The support spring keeps the ring frame and filter plate at the bottom of the wastewater tank. The pull rod and the protrusion cooperate to make the filter plate fit against the ring frame. When it is necessary to clean the debris on the filter plate, the driving component is controlled to work, causing the telescopic rod to move towards the discharge hopper. The telescopic rod drives the crossbar to move, and while the crossbar slides, it pushes the ring frame and filter plate upward. The movement of the telescopic rod also drives the pull rod and the protrusion to move, while compressing the limit spring. When the limit spring is compressed to its limit, as the telescopic rod continues to move, the ring frame and aluminum plate continue to move upward. The telescopic end of the telescopic rod moves upward and pulls the pull rod to rotate, causing the pull rod to pull the protrusion to move, thereby pulling the end of the filter plate away from the discharge hopper to rotate upward, causing the filter plate to rotate and tilt, allowing the debris on the filter plate to enter the discharge hopper.

[0019] After the filter plate remains tilted for a period of time, the control drive works, causing the telescopic rod to move away from the discharge hopper and reset. At the same time, the crossbar and the pull rod also move with the telescopic rod. The support spring returns to its original deformation and pulls the ring frame and filter plate downward. The limit spring returns to its original deformation, causing the protrusion to move. The protrusion cooperates with the pull rod to make the filter plate rotate downward and reset. When the mounting rod moves to the initial position, the ring frame, filter plate, telescopic rod and pull rod all return to their initial positions, and the limit spring and support spring also return to their initial state.

[0020] Optionally, the driving component includes a lead screw rotatably connected in the wastewater tank, a motor driving the lead screw to rotate, and a guide rod fixedly connected in the wastewater tank. The length directions of the lead screw and the guide rod are both arranged along the length direction of the wastewater tank. An installation rod is fixedly connected to the upper end of the telescopic rod. The lead screw passes through the installation rod and is threadedly connected to the installation rod. The guide rod passes through the installation rod and is slidably inserted into it.

[0021] By adopting the above technical solution, the lead screw and guide rod cooperate to drive the installation rod to move along the length of the wastewater pool. The movement of the installation rod can drive the telescopic rod to move. By changing the rotation direction of the motor output shaft, the movement direction of the installation rod can be changed.

[0022] Optionally, the wastewater tank is also equipped with a rinsing assembly for rinsing the filter plates.

[0023] By adopting the above technical solution, the flushing component flushes the debris on the filter plate, thereby flushing the debris to the discharge hopper, so that the debris on the filter plate can be discharged better.

[0024] Optionally, the flushing assembly includes an upper ring sleeve located below the inlet of the wastewater tank, with the opening of the upper ring sleeve facing downwards, and a bottom cylinder slidably inserted into the upper ring sleeve;

[0025] Both the lead screw and the guide rod pass through the upper ring sleeve, wherein the lead screw is threaded into the upper ring sleeve, and the guide rod is slidably inserted into the upper ring sleeve.

[0026] The bottom surface of the bottom cylinder is provided with a flushing hole, and a sealing plate is provided in the bottom cylinder to seal the flushing hole. A vertical rod is fixedly connected to the sealing plate, and a horizontal rod is fixedly connected to the vertical rod. The horizontal rod is fixed to the upper ring.

[0027] Sliding blocks are fixedly connected to the two short side walls of the bottom cylinder. The sliding blocks are slidably connected to the wastewater tank. The sliding trajectory of the sliding blocks is horizontal in the part away from the discharge hopper, and the sliding trajectory is inclined downward in the direction of the discharge hopper in the direction of the discharge hopper.

[0028] By adopting the above technical solution, in the initial state, the bottom cylinder and the upper ring sleeve are located below the inlet end of the wastewater tank. The horizontal and vertical rods cooperate with the sealing plate to close the flushing hole, and the wastewater flows into the upper ring sleeve and the bottom cylinder for storage. When the wastewater fills the bottom cylinder and the upper ring sleeve, the wastewater flows into the bottom of the wastewater tank. During the operation of the motor, the lead screw and the guide rod cooperate to move the upper ring sleeve and the bottom cylinder closer to the discharge hopper. When the sliding block moves downward, the sliding block drives the bottom cylinder to move downward, so that the bottom cylinder and the sealing plate gradually separate, the flushing hole opens, and the water in the bottom cylinder and the upper ring sleeve flows out through the flushing hole, thereby flushing the filter plate. When the output shaft of the motor rotates in the opposite direction, the lead screw and the guide rod cooperate to move the upper ring sleeve and the bottom cylinder back to the initial position. The inner bottom wall of the bottom cylinder gradually approaches the sealing plate. When the upper ring sleeve and the bottom cylinder move to the initial position, the sealing plate seals the flushing hole.

[0029] Optionally, the discharge hopper is inclined, and the discharge hopper gradually tilts downwards in the direction away from the wastewater pool.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By incorporating a regulating tank with a steel shell, a rapid oil separator, a high-efficiency circular air flotation system, a biological fluidized bed, a multi-effect sedimentation reactor, an ozone fluidized bed, a buffer tank, a homogenizing filter, and a product water tank, the time required to build a wastewater treatment system is shortened.

[0032] 2. By setting filter plates, ring frames, telescopic rods, crossbars, tie rods, protrusions, support springs, and limit springs, debris in the wastewater pool can be cleaned into the discharge hopper, reducing the occurrence of filter plate clogging;

[0033] 3. By setting up an upper ring sleeve, bottom cylinder, sliding block, flushing hole and sealing plate, the debris on the filter plate can enter the discharge hopper better. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0043] This application discloses a wastewater treatment equipment. It includes a regulating tank 1, a rapid oil separator 2, a high-efficiency circular flotation unit 3, a biological fluidized bed 4, a multi-effect sedimentation reactor 5, an ozone fluidized bed 6, a buffer tank 61, a homogenizing filter 7, and a product water tank 8, arranged in sequence. The outer shell of each device is made of steel.

[0044] Wastewater enters regulating tank 1. The outlet of regulating tank 1 is connected to the inlet of rapid oil separator 2 via a pipe. The outlet of rapid oil separator 2 is connected to the inlet of high-efficiency circular air flotation 3. The outlet of high-efficiency circular air flotation 3 is connected to the inlet of biological fluidized bed 4. The outlet of biological fluidized bed 4 is connected to the inlet of multi-effect sedimentation reactor 5. The outlet of multi-effect sedimentation reactor 5 is connected to the inlet of ozone fluidized bed 6. The outlet of ozone fluidized bed 6 is connected to the inlet of buffer tank 61. The outlet of buffer tank 61 is connected to the inlet of homogenizing filter 7. The outlet of homogenizing filter 7 is connected to the inlet of product water tank 8. The outlet of product water tank 8 is connected to the inlet of water reuse system. In this embodiment, the outlet of rapid oil separator 2 is pressurized, which can pressurize the wastewater to high-efficiency circular air flotation 3. There is no need to install a wastewater lifting device at the outlet of rapid oil separator 2, which reduces equipment costs.

[0045] The wastewater treatment system also includes a wastewater tank 9, whose outer shell is also made of steel. The wastewater outlet of the homogenizing filter 7 is connected to the inlet of the wastewater tank 9, and the outlet of the wastewater tank 9 is connected to the inlet of the multi-effect sedimentation reactor 5. With this setup, because the casing of the system is made of steel, each unit can be manufactured in the factory, transported to the installation site, and then connected to adjacent units via pipelines. This modular installation of the wastewater treatment system eliminates the need for on-site steel reinforcement and concrete pouring to construct the casing, thus shortening the time required to build the wastewater treatment system.

[0046] To reduce the footprint of the wastewater treatment system, wastewater tank 9 is installed above product water tank 8, and homogenization filter 7 is installed above wastewater tank 9. Since the wastewater flowing into wastewater tank 9 contains impurities, the wastewater containing impurities re-enters the multi-effect sedimentation reactor 5 for sedimentation, thereby removing the impurities from the water. In order to reduce the amount of impurities in the wastewater entering the multi-effect sedimentation reactor 5, wastewater tank 9 is equipped with a mechanism for preliminary cleaning of impurities in the water.

[0047] The inlet and outlet of the wastewater tank 9 are located on the two short side walls of the wastewater tank 9. The outlet of the wastewater tank 9 is fixedly connected to the discharge hopper 91. The length of the discharge hopper 91 is set along the width of the wastewater tank 9. The size of the discharge hopper 91 gradually decreases in the direction away from the wastewater tank 9, and the discharge hopper 91 gradually tilts downward in the direction away from the wastewater tank 9. The horizontal plane inside the wastewater tank 9 is always lower than the discharge hopper 91.

[0048] Wastewater tank 9 is provided with filter plate 92 for filtering impurities, and drive assembly 93 for supporting and controlling the movement of filter plate 92. Drive assembly 93 includes a ring frame 931 disposed below aluminum plate. Each outer wall of ring frame 931 is attached to the corresponding inner wall of wastewater tank 9. The side of filter plate 92 near discharge hopper 91 is hinged to the upper surface of ring frame 931, and the hinge point of filter plate 92 is located on the side of ring frame 931 near discharge hopper 91. The rotation axis of filter plate 92 is set along the width direction of wastewater tank 9.

[0049] Slider 9311 is fixedly connected to the two opposite side walls of the ring frame 931. The wastewater tank 9 has a groove 932 that corresponds to the slider 9311. The length of the groove 932 is set along the height of the wastewater tank 9. Each slider 9311 is slidably inserted into the corresponding groove 932. A support spring 933 is fixedly connected to the lower surface of the slider 9311. The lower end of the support spring 933 is fixedly connected to the bottom wall of the groove 932. The support spring 933 supports the ring frame 931 and the filter plate 92, so that the filter plate 92 and the ring frame 931 are located below the discharge hopper 91.

[0050] The drive assembly 93 includes a crossbar 934 disposed below the ring frame 931. The length of the crossbar 934 is arranged along the width of the wastewater tank 9. The inner sidewalls of the two long sides of the wastewater tank 9 are provided with mating grooves 935 adapted to the crossbar 934. Both ends of the crossbar 934 are inserted into the corresponding mating grooves 935. The end of the mating groove 935 away from the discharge hopper 91 is inclined downward, and the end of the mating groove 935 near the discharge hopper 91 is inclined upward, and the upper end of the mating groove 935 is close to the discharge hopper 91.

[0051] Both ends of the upper surface of the crossbar 934 are fixedly connected to telescopic rods 936 perpendicular to the crossbar 934. Both telescopic rods 936 are located in the ring frame 931. The telescopic rod 936 includes a support rod 9362 fixed to the crossbar 934. The upper end of the support rod 9362 is slidably sleeved with a sleeve 9361. The upper pull member also includes a protrusion 9371 slidably connected to the upper surface of the filter plate 92. The protrusion 9371 corresponds one-to-one with the telescopic rod 936. The cross section of the protrusion 9371 is T-shaped. The upper surface of the filter plate 92 is provided with a groove 921 corresponding to the protrusion 9371. The length direction of the groove 921 is set along the length direction of the wastewater pool 9. The end of the groove 921 near the discharge hopper 91 is at a distance from the hinge point of the filter plate 92.

[0052] A limiting spring 938 is fixedly connected to the side wall of the protrusion 9371 near the discharge hopper 91. The end of the limiting spring 938 away from the protrusion 9371 is fixed to the groove wall of the groove 921 near the discharge hopper 91. The limiting spring 938 limits the protrusion 9371 so that the protrusion 9371 is located at the end of the telescopic rod 936 away from the discharge hopper 91. A pull rod 937 is hinged to the protrusion 9371. The upper end of the pull rod 937 is inclined towards the telescopic rod 936. The upper end of the pull rod 937 is hinged to the corresponding support rod 9362. A through hole for the pull rod 937 to slide is opened on the side wall of the sleeve 9361. The length direction of the through hole is set along the length direction of the sleeve 9361.

[0053] The drive assembly 93 also includes a drive component 939 that drives the telescopic rod 936 to reciprocate along the length of the wastewater tank 9; the drive component 939 includes a lead screw 9391 rotatably connected in the tank body and a guide rod 9392 fixedly connected in the wastewater tank 9. The length directions of the lead screw 9391 and the guide rod 9392 are both arranged along the length direction of the wastewater tank 9, and the lead screw 9391 and the guide rod 9392 are arranged along the width direction of the wastewater tank 9. Both are located at the top of the wastewater tank 9. A motor 9393 that drives the lead screw 9391 to rotate is also installed on the outer wall of the wastewater tank 9.

[0054] The drive unit 939 also includes a mounting rod 9394, which is horizontally positioned and fixedly connected to the top of the two sleeves 9361. The lead screw 9391 and the guide rod 9392 both pass through the mounting rod 9394. The lead screw 9391 and the mounting rod 9394 are threaded together, and the guide rod 9392 and the mounting rod 9394 are slidably inserted into each other.

[0055] In the initial state, the filter plate 92 and the ring frame 931 are located at the bottom of the wastewater tank, and the filter plate 92 is higher than the outlet end of the wastewater tank. The wastewater in the homogenizing filter 7 enters the wastewater tank, and the impurities in the wastewater tank accumulate on the filter plate 92. After a period of time, the operator needs to clean the debris on the filter plate 92 to prevent the filter plate 92 from becoming clogged.

[0056] When cleaning debris from the filter plate 92, the operator controls the motor 9393 to rotate the lead screw 9391. The lead screw 9391 engages with the guide rod 9392, causing the mounting rod 9394 to move closer to the discharge hopper 91. The mounting rod 9394 drives the telescopic rod 936 and the crossbar 934 to move. The crossbar 934 engages with the mating groove 935, causing it to push the ring frame 931 and the filter plate 92 upwards, gradually moving the filter plate 92 to the water surface and closer to the discharge hopper 91. Simultaneously, the support spring 933 is stretched. When the ring frame 931 and the filter plate 92 move upwards to their limit position, the filter plate... The lower side of 92 is aligned with the discharge hopper 91; the telescopic rod 936 moves, causing the protrusion 9371 to move, and at the same time compressing the limit spring 938. When the limit spring 938 is compressed to its limit, as the telescopic rod 936 continues to move, the support rod 9362 pulls the pull rod 937 to rotate. The pull rod 937 pulls the side of the filter plate 92 away from the discharge hopper 91 to rotate upward. The filter plate 92 gradually tilts, causing the debris on the filter plate 92 to slide towards the discharge hopper 91. The discharge end of the discharge hopper 91 is equipped with a collection box for collecting debris. The debris can be discharged from the wastewater pool 9 through the discharge hopper 91, reducing the debris content in the wastewater.

[0057] In order to allow the debris on the filter plate 92 to enter the discharge hopper 91 better, the wastewater pool 9 is also provided with a rinsing assembly 94 for rinsing the debris on the filter plate 92; the rinsing assembly 94 includes a bottom cylinder 941 with a rectangular cross section, the length of the bottom cylinder 941 is set along the width of the wastewater pool 9, and an upper ring sleeve 942 is slidably sleeved on the top of the side wall of the bottom cylinder 941. The bottom cylinder 941 and the upper ring sleeve 942 are both located on the side of the mounting rod 9394 away from the discharge hopper 91.

[0058] Both the lead screw 9391 and the guide rod 9392 pass through the upper ring sleeve 942. The lead screw 9391 and the upper ring sleeve 942 are threaded together, and the guide rod 9392 and the upper ring sleeve 942 are slidably inserted into each other. Sliding blocks 943 are fixedly connected to the two short side walls of the bottom cylinder 941. Sliding grooves 944 that are adapted to the sliding blocks 943 are opened on the two long side inner walls of the wastewater tank 9. The part of the sliding groove 944 away from the discharge hopper 91 is horizontal, and the part of the sliding groove 944 near the discharge hopper 91 gradually slopes downward in the direction of approaching the discharge hopper 91. Each sliding block 943 is slidably inserted into the corresponding sliding groove 944. When the bottom cylinder 941 is located at the end of the lead screw 9391 away from the discharge hopper 91, the bottom cylinder 941 is located directly below the water inlet end of the wastewater tank 9.

[0059] A flushing hole 9411 is provided on the bottom wall of the bottom cylinder 941. The length direction of the flushing hole 9411 is set along the length direction of the bottom cylinder 941. A sealing plate 945 is also provided in the bottom cylinder 941 to block the flushing hole 9411. Several vertical rods 946 are fixedly connected to the upper surface of the sealing plate 945. A top rod 947 is fixedly connected to the upper end of all the vertical rods 946. The length direction of the top rod 947 is set along the width direction of the bottom cylinder 941. Both ends of the top rod 947 are fixed to the inner side wall of the upper ring sleeve 942. When the sliding block 943 is located in the horizontal part of the sliding groove 944, the top rod 947, the vertical rods 946 and the sealing plate 945 cooperate to block the flushing hole 9411, and the water in the bottom cylinder 941 and the upper ring sleeve 942 can be accumulated in both.

[0060] When the motor 9393 is not working, wastewater enters the wastewater pool 9 and falls into the bottom cylinder 941 and upper ring sleeve 942 for accumulation. After the bottom cylinder 941 and upper ring sleeve 942 are full, the wastewater continues to flow into the wastewater pool 9. During the operation of the motor 9393, the side of the filter plate 92 away from the discharge hopper 91 gradually rotates and tilts upward. The upper ring sleeve 942 and the bottom cylinder 941 move together with the mounting rod 9394 towards the discharge hopper 91. The movement of the bottom cylinder 941 drives the sliding block 943 to move. When the sliding block 943 moves to the sliding groove 94... When the bottom cylinder 941 and the upper ring sleeve 942 are located above the lower side of the filter plate 92 in the inclined section 4, as the bottom cylinder 941, the upper ring sleeve 942 and the sliding block 943 continue to move, the bottom cylinder 941 moves downward relative to the upper ring sleeve 942, the sealing plate 945 gradually separates from the bottom cylinder 941, and the water in the bottom cylinder 941 and the upper ring sleeve 942 flows out through the flushing hole 9411 and flushes the filter plate 92, thereby flushing the debris remaining on the filter plate 92 into the discharge hopper 91, so that the debris on the filter plate 92 can enter the discharge hopper 91 better.

[0061] When the operator controls the motor 9393 to work and causes the lead screw 9391 to reverse, the mounting rod 9394, the upper ring sleeve 942, and the bottom cylinder 941 move to their initial positions. The movement of the mounting rod 9394 drives the telescopic rod 936 and the pull rod 937 to move. The telescopic rod 936 drives the crossbar 934 to move. The crossbar 934 engages with the mating groove 935, causing the crossbar 934 to move downward. At the same time, the support spring 933 returns to its original deformation and pulls the ring frame 931 and the filter plate 92 downward to reset. The pull rod 937 drives the protrusion 9371 to move. At the same time, the limit spring 938 returns to its original deformation. The protrusion 9371 engages with the pull rod 937, causing the higher side of the filter plate 92 to gradually rotate downward to reset.

[0062] Simultaneously, the bottom cylinder 941 drives the sliding block 943 to move. The sliding block 943 cooperates with the sliding groove 944, causing the bottom cylinder 941 to move upward relative to the upper ring sleeve 942. The sealing plate 945 gradually seals the flushing hole 9411. When the upper ring sleeve 942, the bottom cylinder 941, and the mounting rod 9394 move to the initial position, the flushing hole 9411 is completely sealed by the sealing plate 945. At this time, water continues to accumulate in the upper ring sleeve 942 and the bottom cylinder 941.

[0063] The implementation principle of a wastewater treatment device according to an embodiment of this application is as follows: Various pre-fabricated devices are transported to the installation site for installation and fixation, and adjacent devices are connected by pipelines. During installation, the wastewater tank 9 is installed above the product water tank 8, and the homogenizing filter 7 is installed above the wastewater tank 9. When treating wastewater, the wastewater flows sequentially through each device for filtration. When the wastewater flows into the wastewater tank 9, it accumulates in the discharge hopper 91 and then falls into the wastewater tank 9. After a period of time, the operator controls the motor 9393 to work, causing the ring frame 931 and filter plate 92 to move upwards. The material gradually emerges from the water and moves to below the discharge hopper 91. At the same time, the filter plate 92 rotates upward. When the filter plate 92 rotates to a certain angle, the flushing hole 9411 opens, and the water in the bottom cylinder 941 and the upper ring sleeve 942 flows out, washing the debris on the filter plate 92 into the discharge hopper 91. The debris is discharged from the wastewater pool 9 through the discharge hopper 91. After a period of time, the operator controls the motor 9393 to work, causing the upper ring sleeve 942, the bottom cylinder 941, the ring frame 931, and the filter plate 92 to move and reset. After the upper ring sleeve 942, the bottom cylinder 941, the ring frame 931, and the filter plate 92 have all reset, the motor 9393 is turned off.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
