Its technical solution includes: an integrated filter assembly, a sedimentation tank installed on the top of the integrated filter assembly, a large impurity filter assembly installed on the top of the sedimentation tank, and a positioning filter assembly installed inside the integrated filter assembly.

Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an integrated sewage treatment device and a treatment method. Background Art

[0002] Integrated sewage treatment equipment is a sewage treatment equipment that integrates sewage treatment, sedimentation, aeration, filtration and other treatment processes. Its main purpose is to treat urban domestic sewage, industrial wastewater, rural sewage, etc. to meet the discharge standards or achieve reuse

[0003] In the patent document with the publication number CN115571962B, an integrated sewage treatment device is disclosed, including a bottom plate, a liquid storage tank is arranged on the bottom plate, and a mixing mechanism and a pressurizing mechanism; the mixing mechanism includes a liquid outlet pipe evenly distributed at the bottom of the side wall of the liquid storage tank, a liquid inlet pipe matching the liquid outlet pipe evenly distributed on the top of the side wall of the liquid storage tank, and the liquid outlet pipe is connected to the liquid inlet pipe through a liquid guide pipe; the pressurizing mechanism includes a piston plate slidably connected to the inner wall of the liquid storage tank, the piston plate is located between the liquid inlet pipe and the liquid outlet pipe, the outer side of the piston plate is evenly distributed with a one-way filtering component that allows the liquid to flow only toward the bottom of the liquid storage tank, and a fixed pressure push-pull component that pushes the piston plate to move is arranged on the bottom plate. Then, through the up and down movement of the piston plate, the sewage flows between the top and bottom of the liquid storage tank via the liquid guide pipe, thereby improving the mixing effect of the sewage and the effect of the sewage and the reaction between the reagent.

[0004] When the above device is in use, the piston plate is used to perform piston movement inside the sewage treatment tank, so that part of the sewage at the bottom is squeezed and circulated upward. However, the sewage at the bottom of the sewage cannot be turned upward to fully contact the chemicals due to the limitation of the piston plate on the filter ball and other mechanisms and the water pressure. Therefore, the purification effect of the water flow is poor. At the same time, many types of chemicals are solid, which are easy to sink to the bottom of the water. Even if they are turned up, they cannot quickly react with the sewage far away, so the efficiency of the use of the chemicals is low.

[0005] Therefore, the present application proposes an integrated sewage treatment device and treatment method. Summary of the invention

[0020] On the other hand, the present application provides: an integrated sewage treatment method, comprising the following steps:

[0021] S1: When sewage enters the equipment, it first passes through the filter grid, and uses the filter grid holes on the filter grid to filter out large particles, and then enters the sedimentation tank, where the suspended matter in the sewage is settled to the bottom of the sedimentation tank by gravity sedimentation;

[0022] S2: In the sedimentation tank, oxygen is added through the aeration device in the sedimentation tank to promote the decomposition of organic matter in the sewage. Then the water flows through the valves on multiple flow-conducting long pipes and flows into the integrated filter tank. In this process, the organic matter in the sewage is further decomposed through the action of the biofilm on the flow-conducting long pipes;

[0023] S3: As the relevant filtered water agent is put into the dosing assembly, a hollow conduit rod is driven to rotate by the first flip motor, and the hollow conduit rod drives the second one-way filter plate to rotate through the auxiliary load-bearing block to stir the sewage and the agent located above, and then the second forward and reverse motor connected to another hollow rotating rod drives the first one-way filter plate to move toward one side of the two-way threaded rod, and then the second one-way filter plate and the first one-way filter plate synchronously stir the sewage, so that the sewage is in an active state;

[0024] S4: As the two hollow conduit rods move to the middle position of the bidirectional threaded rod, the lower limiting guide block and the upper limiting guide block rotate to fit on the upper and lower sides of the fixed guide block, and the floccules generated by sewage treatment are fully adhered to the multiple attachment ropes due to the impact of water flow;

[0025] S5: After the integrated filter tank carries out the final step of accelerating the dirt precipitation on the sewage entering the interior, the valve assembly is opened to cause the filtered water to flow through the solid-liquid separation net between the final collection tank and the integrated filter tank, filtering out the remaining suspended matter and microorganisms, and finally obtaining effluent that meets the emission standards.

[0026] Compared with the prior art, the present invention has the following beneficial technical effects:

[0027] 1. Since the threads at both ends of the two-way threaded rod are opposite, the two hollow rotating rods drive the first one-way filter plate and the second one-way filter plate to move toward one side of the two-way threaded rod. The second one-way filter plate pushes the sewage above, causing the medicine in the dosing assembly above to diffuse rapidly toward the sewage below. The sewage below is pushed and stirred by the first one-way filter plate, causing the dirt particles at the bottom to float upward and fully contact and react with the medicine, thereby improving the purification effect of the medicine and preventing the dirt from settling to the bottom and failing to be completely purified.

[0028] 2. A plurality of fan-shaped areas are formed by the lower limiting guide block, the fixed guide block and the upper limiting guide block. When the water flow pushed by the first one-way filter plate and the second one-way filter plate impacts up and down, the flocs generated by the sewage treatment are fully adhered to the plurality of attachment ropes due to the impact of the water flow. At the same time, the filter floating ball rotates along the guidance of the water flow, which can better adhere to the flocs floating in the sewage;

[0029] 3. While the guide screw is stirring, it slides along the auxiliary chute block through the limiting sleeve ring, guiding and pushing the water flow horizontally, so that the particles adhering to the integrated filter tank are dropped by the water pressure and are in an active state, so as to prevent the particles from adhering to the inside of the integrated filter tank and being difficult to clean later, so that the dirt particles can be uniformly collected in the solid-liquid separation net at the bottom of the integrated filter tank by gravity later;

[0030] 4. With the spring force of the vertical spring and the transverse springs on the upper and lower sides, the filter grid can vibrate in all directions within the range connected to the corresponding placement block, causing large particles that may cover the filter grid holes to shake and displace or jump a distance from the filter grid, thereby preventing the filter assembly from reducing the filtration output of sewage due to clogging of the filter holes.

DETAILED DESCRIPTION

[0042] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] Example 1

[0044] like Figure 5-Figure 9 As shown, an integrated sewage treatment device proposed by the present invention comprises an integrated filter assembly 1, a sedimentation tank 3 installed on the top of the integrated filter assembly 1, a large impurity filter assembly 2 installed on the top of the sedimentation tank 3, and a positioning filter assembly 4 installed inside the integrated filter assembly 1;

[0045] The integrated filter assembly 1 includes an integrated filter tank 101, and a detachable solid-liquid separation net is installed at the bottom of the integrated filter tank 101. As the last step of solid-liquid separation of the water flow, a plurality of flow-conducting long tubes 103 are fixedly connected to the outside of the integrated filter tank 101, and the plurality of flow-conducting long tubes 103 are arranged in a ring state with respect to the outside of the integrated filter tank 101. After the sewage in the sedimentation tank 3 is precipitated, oxygen is added through the aeration assembly inside the sedimentation tank 3 to promote the decomposition of organic matter in the sewage. The valves connected to the plurality of flow-conducting long tubes 103 are opened to allow the sewage to flow along the flow-conducting long tubes 103 to the integrated filter tank 101, and a replaceable biofilm is installed on one side of the flow-conducting long tube 103 located inside the sedimentation tank 3 to further decompose the organic matter in the sewage through the action of the biofilm.

[0046] In this embodiment, the positioning filter assembly 4 includes a bidirectional threaded rod 416, six fixed guide blocks 411 are fixedly connected to the outer side of the bidirectional threaded rod 416, and the multiple fixed guide blocks 411 are arranged in a ring-shaped distribution state with respect to the inner wall of the integrated filter tank 101, and the upper and lower sides of the bidirectional threaded rod 416 are threadedly connected to two hollow conduit rods 402, and the two hollow conduit rods 402 are fixedly connected to two auxiliary bearing blocks 404, the bottom of one auxiliary bearing block 404 is fixedly connected to the first one-way filter plate 401, and the top of the other auxiliary bearing block 404 is fixedly connected to the second one-way filter plate 403, the internal threads of the two hollow conduit rods 402 are connected to the bidirectional threaded rod 416 with the upper and lower surfaces arranged in an opposite thread state, and the outer side of the bidirectional threaded rod 416 is fixedly connected to multiple fixed guide blocks 411 arranged in a ring-shaped distribution with respect to the inner wall of the integrated filter tank 101, and the multiple fixed guide blocks 411 are fixedly installed on the inner wall of the integrated filter tank 101;

[0047] The two hollow catheter rods 402 are internally slidably connected with the same number of guide positioning columns 421, and the outer sides of the two guide positioning columns 421 are fixedly connected with a plurality of auxiliary arc blocks 415. The outer sides of the two guide positioning columns 421 are slidably connected with hollow rotating rods 412 through a plurality of auxiliary arc blocks 415, and one hollow rotating rod 412 is fixedly installed at the bottom of the integrated filter tank 101, and the other hollow rotating rod 412 is fixedly installed at the top of the integrated filter tank 101. The top of the integrated filter tank 101 is fixedly installed with a dosing assembly 414. The relevant filtered water medicine is put into the medicine component 414, and the hollow conduit rod 402 located at the top of the integrated filter tank 101 is fixedly connected to the first forward and reverse rotation motor. The first flip motor drives a hollow conduit rod 402 to rotate, and the hollow conduit rod 402 drives the second one-way filter plate 403 to rotate through the auxiliary bearing block 404 to stir the sewage and the medicine located above. The hollow conduit rod 402 is guided by the threads of the bidirectional threaded rod 416, and the bidirectional threaded rod 416 is fixed by the fixed guide block 411 and is positioned immovably, so that the hollow conduit rod 40 The side away from the bidirectional threaded rod 416 drives the guide positioning column 421 to slide through the multiple auxiliary arc blocks 415 in the limit position in the hollow rotating rod 412, so that the first one-way filter plate 401 above slides toward the direction of the bidirectional threaded rod 416. Similarly, the other hollow guide rod 402 located below the integrated filter tank 101 drives the first one-way filter plate 401 to rotate. Since the threads at both ends of the bidirectional threaded rod 416 are opposite, the second forward and reverse motor connected to the other hollow rotating rod 412 drives the first one-way filter plate 401 to the bidirectional threaded rod 416. One side of the threaded rod 416 moves, and then the second one-way filter plate 403 and the first one-way filter plate 401 synchronously stir the sewage, so that the sewage is in an active state. At the same time, the second one-way filter plate 403 pushes the sewage above, causing the medicine in the dosing assembly 414 located above to quickly diffuse toward the sewage below, and the sewage located below is pushed and stirred by the first one-way filter plate 401, causing the dirt particles at the bottom to float upward and fully contact and react with the medicine, thereby improving the purification effect of the medicine and preventing the dirt from sinking to the bottom and not being able to be completely purified.

[0048] Example 2

[0049] like Figure 1-Figure 10As shown, based on Example 1, the outer sides of the two auxiliary load-bearing blocks 404 are connected with two groups of bolt connecting rods 406 by bolts, one side of the bolt connecting rod 406 is fixedly connected with an auxiliary slide block 413, one side of the auxiliary slide block 413 is slidably connected with a limited collar 405, the inner rotation of the limited collar 405 is connected with a guide screw 417, the guide screw 417 is slidably connected to the auxiliary slide block 413 through the limited collar 405, and as the first one-way filter plate 401 and the second one-way filter plate 403 rotate, the guide screw 417 is slidably connected to the auxiliary slide block 413 through the bolt connecting rod 406 and the auxiliary slide. Block 413 drives the guide screw 417 to rotate together. At the same time, the guide screw 417 rotates along the limiting collar 405 due to the guidance of the water flow, and the threads on the surface of the guide screw 417 further guide the water flow to stir in one direction. In this case, as the sewage is stirred along the guide screw 417, some particles inside it are generated into small particles as the reagents react. During the rotation of the guide screw 417, the centrifugal force causes the particles to adhere to the integrated filter tank 101, avoiding sinking to the bottom of the integrated filter tank 101 again and affecting the next step of filtration.

[0050] Example 3

[0051] like Figure 6 and Fig.10 As shown, based on the above-mentioned embodiment 1 or 2, a plurality of lower limiting guide blocks 410 are fixedly connected to the outer side of a hollow conduit rod 402, and the plurality of lower limiting guide blocks 410 are arranged in a ring-shaped distribution with respect to the inner wall of the integrated filter tank 101, and a plurality of upper limiting guide blocks 407 are fixedly connected to the outer side of another hollow conduit rod 402, and the plurality of upper limiting guide blocks 407 are arranged in a ring-shaped distribution with respect to the inner wall of the integrated filter tank 101, and a plurality of attachment ropes 408 of different lengths are fixedly connected to both sides of the plurality of upper limiting guide blocks 407, the lower limiting guide blocks 410 and the fixed guide blocks 411, and a plurality of filter floating balls 408 are rotatably connected to the surface of each attachment rope 408. 9. As the two hollow conduit rods 402 move to the middle position of the bidirectional threaded rod 416, the lower limiting guide block 410 and the upper limiting guide block 407 rotate to fit on the upper and lower sides of the fixed guide block 411, and the lower limiting guide block 410, the fixed guide block 411 and the upper limiting guide block 407 form a plurality of fan-shaped areas. When the water flow pushed by the first one-way filter plate 401 and the second one-way filter plate 403 impacts up and down, the flocs generated by the sewage treatment are fully adhered to the plurality of attachment ropes 408 due to the impact of the water flow, and at the same time, the filter floating ball 409 rotates along the guidance of the water flow, which can better adhere to the flocs floating in the sewage.

[0052] In this embodiment, the internal rotation of the guide screw 417 is connected to the plug-in positioning rod 418, and the top of the plug-in positioning rod 418 is hinged with a tilting rod 419. One side of the tilting rod 419 is hinged with a hinged slider 420, and the number of the hinged sliders 420 is two groups, one group of hinged sliders 420 is fixedly connected to the upper limit guide block 407, and the other group of hinged sliders 420 is fixedly connected to the lower limit guide block 410. When the plurality of guide screws 417 move toward the direction of the bidirectional threaded rod 416 along the first one-way filter plate 401 and the second one-way filter plate 403, the tilting rod 419 moves along the upper limit guide block 407 and the lower limit guide block. When the filter element 410 is pressed downward between the upper and lower limit guide blocks 407 and 410, the inclined rod 419 is limitedly bent in the upper limit guide block 407 and the lower limit guide block 410 through the hinged slider 420 and the inserted positioning rod 418, so that the guide screw 417 slides along the auxiliary slide block 413 through the limiting collar 405 while stirring, and guides and pushes the water flow laterally, so that the particles adhering to the integrated filter tank 101 are caused to fall into an active state by the water pressure, so as to avoid the particles adhering to the inside of the integrated filter tank 101 and being difficult to clean later, so that the dirt particles can be uniformly collected in the solid-liquid separation net at the bottom of the integrated filter tank 101 by gravity in the later stage.

[0053] Example 4

[0054] like Figure 1-Figure 3 As shown, based on the above-mentioned embodiment 1 or 3, the integrated filter component 1 also includes a final collecting tank 102, and a valve component for controlling the water output is installed on the final collecting tank 102. The final collecting tank 102 is installed at the bottom of the integrated filter tank 101. After the integrated filter tank 101 performs the final step of chemical acceleration of dirt precipitation on the sewage entering the interior, the valve component is opened to cause the filtered water to pass through the filter net between the final collecting tank 102 and the integrated filter tank 101, and the residual suspended matter and microorganisms are filtered out, and finally the effluent that meets the emission standards is obtained. At this point, all the various treatment processes are completed together, reducing the equipment footprint and reducing consumption costs.

[0055] In this embodiment, the large impurity filtering assembly 2 includes a large impurity filtering box 201, which is fixedly installed on the top of the integrated filtering tank 101. Two auxiliary guide rods 206 are fixedly installed inside the large impurity filtering box 201. The top ends of the two auxiliary guide rods 206 are fixedly connected to auxiliary blocking plates 208. The bottom ends of the auxiliary blocking plates 208 are fixedly connected to hydraulic conduits 207. The bottom of the hydraulic conduits 207 is fixedly connected to a positioning support rod 205. The bottom end of the positioning support rod 205 is fixedly connected to a filter grid 204. A plurality of filter grid holes 209 are opened on the filter grid 204. A corresponding placement block 202 is installed on the outer side of the filter grid 204. The corresponding placement block 202 is slidably installed on the two auxiliary guide rods 206. When the sewage enters the equipment, it first passes through the filter grid 204, and the large particulate matter is filtered out by using the filter grid holes 209 on the filter grid 204. Then it enters the sedimentation tank 3, and the suspended matter in the sewage is precipitated to the bottom by gravity sedimentation. In the sedimentation tank 3, oxygen is added through the aeration device in the sedimentation tank 3 to promote the decomposition of organic matter in the sewage, and then the water flows through the valves on the multiple flow-conducting long pipes 103 to flow into the integrated filter tank 101;

[0056] When a single sewage is treated in the sedimentation tank 3 and then transferred to the integrated filter tank 101, the hydraulic conduit 207 drives the positioning support rod 205 to move upward through hydraulic drive, and at the same time, the positioning support rod 205 brings the filter mesh 204 and the corresponding placement block 202 to move upward along the surface of the auxiliary guide rod 206 to the uppermost end. Then, the staff can use cleaning tools to clean the inside of the sedimentation tank 3.

[0057] Example 5

[0058] like Figure 1-Figure 4 As shown, based on the above-mentioned embodiment 1 or 4, the surface of the corresponding placement block 202 is provided with an arc-shaped guide plate 203. When the sewage flows from the upper water inlet to the filter screen 204, the sewage can be gathered on the filter screen 204 along the slope of the arc-shaped guide plate 203 for filtration. The filter screen 204 is located inside the corresponding placement block 202 and is fixedly connected with transverse springs 210 on both upper and lower sides. A vertical spring 211 is fixedly connected between the filter screen 204 and the corresponding placement block 202. As the sewage impacts the filter screen 204, the filter screen 204 is The net 204 is impacted by the external water flow and shakes along the guidance of the water flow under the internal limit of the corresponding placement block 202. With the spring force of the vertical spring 211 and the transverse springs 210 on the upper and lower sides, the filter mesh 204 can vibrate in all directions within the range connected to the corresponding placement block 202, causing large particles that may cover the filter mesh holes 209 to shake and displace or jump a distance from the filter mesh 204, thereby avoiding the filter assembly from reducing the filtration output of sewage due to the clogging of the filter holes.

[0059] On the other hand, the present application provides: an integrated sewage treatment method, comprising the following steps:

[0060] S1: When the sewage enters the equipment, it first passes through the filter grid 204, and the large particles are filtered out by the filter grid holes 209 on the filter grid 204, and then enters the sedimentation tank 3, and the suspended matter in the sewage is settled to the bottom of the sedimentation tank 3 by gravity sedimentation;

[0061] S2: In the sedimentation tank 3, oxygen is added through the aeration device in the sedimentation tank 3 to promote the decomposition of organic matter in the sewage, and then the water flows through the valves on the multiple flow-conducting long pipes 103 to flow into the integrated filter tank 101. In this process, the organic matter in the sewage is further decomposed by the action of the biofilm on the flow-conducting long pipes 103;
