Description

Technical Field

[0001] This invention belongs to the field of oxidation ditch technology, and specifically relates to a sewage oxidation ditch system. Background Technology

[0002] An oxidation ditch is an activated sludge treatment system. Its aeration tank is a closed ditch, so its hydraulic flow pattern differs from the traditional activated sludge process. It is a circulating aeration ditch with interconnected ends, also known as a circulating aeration tank. The earliest oxidation ditches were not built of reinforced concrete, but were earthen ditches with slope protection, using intermittent water inflow and intermittent aeration. In this sense, the oxidation ditch was originally a batch process technology for treating wastewater. The oxidation ditch process is a variation of the activated sludge process, belonging to the extended aeration activated sludge process. In 1954, the Netherlands built the world's first oxidation ditch wastewater treatment plant. Its prototype was an intermittently operating reaction tank with a ring-shaped racetrack-like sloping wall, used as an aeration tank during the day and a sedimentation tank at night. Its biochemical oxygen demand (BOD) removal rate could reach 97%. Due to its simple structure and good treatment effect, it attracted widespread interest and attention from countries around the world.

[0003] In existing wastewater oxidation ditches, air is injected into the wastewater through a water pump to oxygenate it. The wastewater is then discharged from the oxidation ditch into a sedimentation tank for sedimentation. However, because impurities in the wastewater are prone to deposition, when the wastewater undergoes oxidation in the oxidation ditch, these impurities settle at the bottom of the ditch, resulting in a large accumulation of impurities and reducing the storage capacity of the wastewater in the oxidation ditch.

[0004] Therefore, a wastewater oxidation ditch system is needed to solve the problem in existing technologies where impurities in wastewater easily accumulate in the oxidation ditch, reducing the amount of wastewater stored in the oxidation ditch. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater oxidation ditch system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater oxidation ditch system, comprising an oxidation ditch body, wherein a first rotating rod is rotatably connected to the inner side wall of the oxidation ditch body at the middle position of one side close to each other, a water distribution column is fixed to the outer side wall of the first rotating rod, and a plurality of circumferentially distributed water collection troughs are opened on the outer side wall of the water distribution column, and symmetrically distributed fixed rods are fixed on both sides of the top surface of the oxidation ditch body, a side block is fixed to one side of the top surface of the fixed rod, and a threaded rod is rotatably connected between the side block and the fixed rod at one side close to each other, a limiting port is opened on the top surface of the fixed rod, a movable rod is movably engaged in the limiting port, the top of the movable rod is movably connected to the outer side wall of the threaded rod, a push plate is fixed to one side adjacent to the movable rod, and a flushing assembly is provided on the top surface of the oxidation ditch body.

[0007] Furthermore, the rinsing assembly includes a top bar, which is fixed at the middle of the top surface of the oxidation ditch body. A water pump is fixed at the middle of the top surface of the top bar. A water pipe is connected to the input end of the water pump, and a connecting pipe is connected to the output end of the water pump. A drain pipe is connected through the bottom surface of the connecting pipe, and the drain pipe is fixed to the bottom of one side of the inner wall of the oxidation ditch body.

[0008] Furthermore, symmetrically distributed side rods are fixed to the top of the opposite two sides of the outer wall of the oxidation ditch body. A second rotating rod is rotatably connected between adjacent side rods that are close to each other on one side. A second bevel gear is fixed to both sides of the outer wall of the second rotating rod, and the second bevel gear meshes with the first bevel gear.

[0009] Furthermore, fixing plates are fixed on both sides of the top of one side of the outer wall of the oxidation ditch body, and a servo motor is fixed on the top surface of the fixing plate. The output end of the servo motor is fixed to one end of the second rotating rod.

[0010] Furthermore, a first gear is fixed to one end of the outer wall of the first rotating rod, an external motor is fixed to one side of the outer wall of the oxidation ditch body, and a second gear is fixed to the output end of the external motor, the second gear meshing with the first gear.

[0011] Furthermore, a water outlet pipe is connected through the bottom of one side of the outer wall of the oxidation ditch body, and a first valve is provided on the outer wall of the water outlet pipe.

[0012] Furthermore, a water inlet pipe is connected to the top of the other side of the outer wall of the oxidation ditch body, and a second valve is provided on the outer wall of the water inlet pipe.

[0013] Compared with the prior art, the wastewater oxidation ditch system provided by the present invention has at least the following beneficial effects:

[0014] (1) By setting the second rotating rod, the second bevel gear and the first bevel gear, the threaded rod can be reciprocated, thereby causing the push plate to move back and forth to push the sewage, thus avoiding the sedimentation of impurities in the sewage. By setting the water distribution column and water collection tank, the sewage on one side of the oxidation ditch body can be transferred to the other side, thereby stirring the sewage at the top of the oxidation ditch body, further avoiding the sedimentation of impurities in the sewage, and increasing the oxygen content in the sewage. Thus, the sewage at the top and bottom of the oxidation ditch body can be stirred separately, avoiding the sedimentation of impurities in the sewage in the oxidation ditch body, thus reducing the storage capacity of sewage in the oxidation ditch body.

[0015] (2) By setting up a water pump, the sewage in the oxidation ditch body can be injected into the connecting pipe and then discharged from the drain pipe, so that the bottom of the oxidation ditch body can be flushed, and the impurities in the sewage at the bottom of the oxidation ditch body will not settle in the oxidation ditch body when the sewage is discharged, and the storage capacity of sewage in the oxidation ditch body will be further avoided.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] The applicant's research found that existing technologies suffer from the problem of impurities in wastewater easily accumulating in the oxidation ditch, reducing the amount of wastewater that can be stored in the ditch. Therefore, Example 1 proposes a wastewater oxidation ditch system, such as... Figure 1-5 As shown, the wastewater oxidation ditch system includes an oxidation ditch body 100. A first rotating rod 101 is rotatably connected to the inner side wall of the oxidation ditch body 100 at the middle of one side. A water distribution column 102 is fixed to the outer side wall of the first rotating rod 101. Several circumferentially distributed water collection troughs 103 are opened on the outer side wall of the water distribution column 102. Fixed rods 300 are symmetrically distributed on both sides of the top surface of the oxidation ditch body 100. A side block 302 is fixed to one side of the top surface of the fixed rod 300. A threaded rod 301 is rotatably connected between the side block 302 and the fixed rod 300 at one side. A limiting port 306 is opened on the top surface of the fixed rod 300. A movable rod 304 is movably engaged in the limiting port 306. The top of the movable rod 304 is movably connected to the outer side wall of the threaded rod 301. A push plate 305 is fixed to one side of the adjacent movable rod 304. A flushing assembly is provided on the top surface of the oxidation ditch body 100.

[0031] As a further embodiment of the present invention, the rinsing assembly includes a top bar 500, which is fixed at the middle position of the top surface of the oxidation ditch body 100. A water pump 501 is fixed at the middle of the top surface of the top bar 500. A water pipe 502 is connected to the input end of the water pump 501, and a connecting pipe 503 is connected to the output end of the water pump 501. A drain pipe 504 is connected through the bottom surface of the connecting pipe 503, and the drain pipe 504 is fixed to the bottom of one side of the inner wall of the oxidation ditch body 100.

[0032] The water pump 501 allows the sewage inside the oxidation ditch body 100 to be pumped into the connecting pipe 503, and then into the discharge pipe 504. The sewage is then discharged from the discharge pipe 504 to the bottom of the oxidation ditch body 100, thereby pushing the sewage at the bottom of the oxidation ditch body 100 and preventing impurities in the sewage from settling.

[0033] As a further embodiment of the present invention, the top of the opposite two sides of the outer side wall of the oxidation ditch body 100 is respectively fixed with symmetrically distributed side rods 400, and a second rotating rod 401 is rotatably connected between adjacent side rods 400 and one side of each other. A second bevel gear 402 is fixed on both sides of the outer side wall of the second rotating rod 401, and the second bevel gear 402 meshes with the first bevel gear 303.

[0034] The second rotating rod 401 and the second bevel gear 402 enable the first bevel gear 303 to rotate, which in turn drives the threaded rod 301 to rotate, causing the push plate 305 to move and push the sewage in the oxidation ditch body 100, further preventing impurities from settling.

[0035] As a further embodiment of the present invention, fixing plates 403 are respectively fixed on both sides of the top of one side of the outer wall of the oxidation ditch body 100, and a servo motor 404 is fixed on the top surface of the fixing plate 403. The output end of the servo motor 404 is fixed to one end of the second rotating rod 401.

[0036] The servo motor 404 enables the second rotating rod 401 to reciprocate, which in turn enables the threaded rod 301 to reciprocate, allowing the push plate 305 to reciprocate within the oxidation ditch body 100, thus pushing the wastewater within the oxidation ditch body 100 and further preventing the sedimentation of impurities in the wastewater.

[0037] This solution has the following working process: When treating the sewage in the oxidation ditch body 100 to prevent sedimentation, two servo motors 404 are started. The servo motors 404 reciprocate, driving the second rotating rod 401 to reciprocate. The second rotating rod 401 reciprocates, driving the second bevel gear 402 to reciprocate. The second bevel gear 402 reciprocates, driving the first bevel gear 303 to reciprocate, which in turn causes the threaded rod 301 to reciprocate. The threaded rod 301 reciprocates, driving the moving rod 304 to move back and forth, ultimately driving the push plate 305 to move back and forth, thus pushing the sewage. An external motor 201 is started, driving the second gear 202 to rotate. The second gear 202 rotates, driving the first gear 200 to rotate. The first gear 200 rotates, driving the first rotating rod 101 to rotate. The first rotating rod 101 rotates, driving the water distribution column 102 to rotate. The water collection tank 103 transfers the sewage from one side of the oxidation ditch body 100 to the other side, further pushing the sewage and increasing the oxygen content in the sewage.

[0038] When discharging wastewater, the first valve 602 is opened, and the external motor 201 and servo motor 404 are turned off. Wastewater is discharged from the outlet pipe 601 into the sedimentation tank. When the amount of water in the wastewater decreases to the preset water level, the water pump 501 is started. The water pump 501 pumps the wastewater into the connecting pipe 503 and discharges it from the outlet pipe 504. This flushes and pushes the wastewater at the bottom of the oxidation ditch body 100, so that the wastewater at the bottom is still in a turbulent state when it is discharged, thus preventing impurities from settling at the bottom of the oxidation ditch body 100 when the wastewater is discharged.

[0039] As can be seen from the above working process: the second rotating rod 401, the second bevel gear 402 and the first bevel gear 303 enable the threaded rod 301 to reciprocate, thereby causing the push plate 305 to reciprocate and push the sewage, thus preventing the sedimentation of impurities in the sewage. The water distribution column 102 and the water collection tank 103 enable the sewage on one side of the oxidation ditch body 100 to be transferred to the other side, thereby stirring the sewage at the top of the oxidation ditch body 100, further preventing the sedimentation of impurities in the sewage, and increasing the oxygen content in the sewage. This allows the sewage at the top and bottom of the oxidation ditch body 100 to be stirred separately, preventing impurities in the sewage from settling in the oxidation ditch body 100 and reducing the storage capacity of sewage in the oxidation ditch body 100.

[0040] By using the water pump 501, the sewage in the oxidation ditch body 100 can be injected into the connecting pipe 503 and then discharged from the drain pipe 504, thereby flushing the bottom of the oxidation ditch body 100. This prevents impurities in the sewage from settling in the oxidation ditch body 100 when the sewage is discharged, and further prevents the amount of sewage stored in the oxidation ditch body 100 from decreasing.

[0041] As a further embodiment of the present invention, a first gear 200 is fixed to one end of the outer wall of the first rotating rod 101, an external motor 201 is fixed to one side of the outer wall of the oxidation ditch body 100, and a second gear 202 is fixed to the output end of the external motor 201, the second gear 202 meshing with the first gear 200.

[0042] The first rotating rod 101 can rotate by the first gear 200, the second gear 202 and the external motor 201, thereby driving the water distribution column 102 to rotate, transferring the sewage from one side to the other side of the oxidation ditch body 100, and increasing the oxygen content in the sewage.

[0043] As a further embodiment of the present invention, a water outlet pipe 601 is connected to the bottom of one side of the outer wall of the oxidation ditch body 100. The water outlet pipe 601 is connected to the sedimentation tank, and a first valve 602 is provided on the outer wall of the water outlet pipe 601.

[0044] The wastewater after oxidation treatment can be discharged into the sedimentation tank through the outlet pipe 601.

[0045] As a further embodiment of the present invention, an inlet pipe 600 is connected to the top of the other side of the outer wall of the oxidation ditch body 100, and a second valve 603 is provided on the outer wall of the inlet pipe 600.

[0046] The wastewater can enter the oxidation ditch body 100 through the inlet pipe 600.

[0047] In summary: When treating the wastewater in the oxidation ditch body 100 to prevent sedimentation, two servo motors 404 are activated. The servo motors 404 reciprocate, driving the second rotating rod 401 to reciprocate. The second rotating rod 401 reciprocates, driving the second bevel gear 402 to reciprocate. The second bevel gear 402 reciprocates, driving the first bevel gear 303 to reciprocate, which in turn causes the threaded rod 301 to reciprocate. The threaded rod 301 reciprocates, driving the moving rod 304 to reciprocate, which in turn drives the push plate 305 to reciprocate, thus pushing the wastewater. An external motor 201 is activated, driving the second gear 202 to rotate. The second gear 202 rotates, driving the first gear 200 to rotate. The first gear 200 rotates, driving the first rotating rod 101 to rotate. The first rotating rod 101 rotates, driving the water distribution column 102 to rotate. The water collection tank 103 transfers the wastewater from one side of the oxidation ditch body 100 to the other side, further pushing the wastewater and increasing the oxygen content in the wastewater.

[0048] When discharging wastewater, the first valve 602 is opened, and the external motor 201 and servo motor 404 are turned off. Wastewater is discharged from the outlet pipe 601 into the sedimentation tank. When the amount of water in the wastewater decreases to the preset water level, the water pump 501 is started. The water pump 501 pumps the wastewater into the connecting pipe 503 and discharges it from the outlet pipe 504. This flushes and pushes the wastewater at the bottom of the oxidation ditch body 100, so that the wastewater at the bottom is still in a turbulent state when it is discharged, thus preventing impurities from settling at the bottom of the oxidation ditch body 100 when the wastewater is discharged.

[0049] The oxidation ditch body 100, external motor 201, servo motor 404 and water pump 501 can be purchased from the market. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in the specification.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
