Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, and in particular to a high-efficiency integrated sewage treatment device. BACKGROUND

[0002] With the acceleration of urbanization and the improvement of environmental protection requirements, sewage treatment has become an important part of environmental protection. The existing high-efficiency integrated treatment equipment includes sedimentation treatment, microbial treatment, chemical treatment, anaerobic treatment, and pH value treatment. Among them, anaerobic treatment, as a high-efficiency sewage treatment technology, has the advantages of low energy consumption, low sludge production, energy recovery, and is widely used in the field of sewage treatment.

[0003] At present, the anaerobic treatment equipment is a traditional anaerobic reactor, which includes an upflow anaerobic sludge bed and an anaerobic filter. The upflow anaerobic sludge bed is most commonly used, which includes a water inlet system, a sludge bed, a three-phase separator, a water outlet system, and a biogas collection system. The sewage is evenly distributed to the reactor through the water inlet system at the bottom and is subjected to anaerobic degradation by the sludge layer.

[0004] The existing reactor adopts bottom water distribution, and the water distribution direction is fixed. The uneven distribution of the sludge layer leads to a decrease in anaerobic treatment efficiency and incomplete treatment. Therefore, as disclosed in CN115583725B, a vertical anaerobic reactor for sewage treatment is disclosed, which includes a vertical tank body and a mud-water inlet, a sewage inlet, an internal circulation cylinder and a gas outlet arranged from bottom to top along the vertical tank body. The upper part of the internal circulation cylinder is a conical section with a large upper end and a small lower end, and the lower part is a straight cylinder section. The internal circulation cylinder is fixedly connected with the inner wall of the vertical tank body by the conical section. The conical section is provided with an overflow hole, the bottom of the straight cylinder section is closed, and the sidewall of the bottom of the straight cylinder section is provided with a circulating port. The sidewall of the straight cylinder section above the circulating port is provided with a water outlet, and the water outlet is provided with a water outlet pipe extending out of the vertical tank body. A filter screen is arranged in front of the water outlet in the straight cylinder section. The circulating port and the mud-water inlet are connected by a circulating pipeline arranged outside the vertical tank body, and the circulating pipeline is provided with a circulating pump.

[0005] The above-mentioned vertical anaerobic reactor, by arranging the internal circulation cylinder and the circulating pipeline, the upwardly rising mud-water mixture enters the internal circulation cylinder, realizing the recycling of the sludge and the adjustable and controllable internal circulation amount. The internal circulation cylinder is provided with a reinforced separation element, which effectively drives the floating sludge downward, breaks the material layering caused by the floating sludge, and realizes the continuous stirring of the sludge at the bottom of the vertical tank body through the sewage distribution pipe, forming a good fluidization effect, promoting the recycling of anaerobic bacteria, and improving the mass transfer and degradation efficiency.

[0006] The vertical anaerobic reactor mixes the sludge anaerobic layer in a form of overturning to make the sludge layer uniformly distributed, which can solve the problem of uneven distribution of the sludge anaerobic layer to a certain extent, but the overturning mode is single, the sludge layer redistribution efficiency is low, and the sewage treated by anaerobic treatment in the upper layer is brought down by the up-down overturning, which collides with the original sewage not treated by anaerobic treatment, thereby hindering the normal rising of the sewage and affecting the normal anaerobic treatment of the sewage, and reducing the anaerobic treatment efficiency.

[0007] Therefore, a new type of high-efficiency integrated sewage treatment device can be used to solve the problems of the prior art. SUMMARY

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0051] Embodiment one: refer to Figures 1-2 A high-efficiency integrated sewage treatment device, comprising a support, further comprising a sedimentation filter unit 1, an anaerobic treatment unit 2, a microbial treatment unit 3, a chemical treatment unit 4 and a pH adjustment unit 5 fixedly installed on the support;

[0052] The sedimentation filter unit 1 is used for treating large-particle suspended matter in sewage, the anaerobic treatment unit 2 is used for treating organic matter in sewage by anaerobic bacteria, the microbial treatment unit 3 is used for treating harmful nitrogen and phosphorus substances in sewage, the chemical treatment unit 4 is used for treating harmful heavy metal substances in sewage, and the pH adjustment unit 5 is used for adjusting the pH value of sewage after a series of treatments.

[0053] The sedimentation filter unit 1, the anaerobic treatment unit 2, the microbial treatment unit 3, the chemical treatment unit 4 and the pH adjustment unit 5 are connected through the water supply and drainage system 6.

[0054] The sedimentation filter unit 1 is mainly used for removing suspended matter, particulate matter and part of colloidal matter in sewage, providing pretreatment for subsequent treatment, and making suspended solids in sewage settle to the bottom by gravity, and further removing fine particles and colloidal matter by filtering through a filter screen, filter material or a multi-medium filter;

[0055] Microbial treatment unit 3 utilizes the metabolic activity of aerobic microorganisms to degrade pollutants such as nitrogen and phosphorus in wastewater. Nitrogen is removed through nitrification and denitrification, while phosphorus-accumulating bacteria absorb phosphorus under aerobic conditions and remove it through sludge discharge.

[0056] Chemical treatment unit 4 removes pollutants that are difficult to biodegrade in sewage by adding chemical agents, or enhances the treatment effect. It adds coagulants to aggregate colloidal particles into larger flocs for easier sedimentation, and removes refractory organic matter or heavy metals by using oxidants or reducing agents.

[0057] The pH regulating unit 5 adjusts the pH value of the sewage to make it suitable for the operating conditions of subsequent treatment or to meet the discharge standards by adding acid or alkali to adjust the pH value of the sewage.

[0058] Example 2: This example differs from the example 1 in that: Figures 3-19 The anaerobic treatment unit 2 is composed of an anaerobic reactor 7 and a water distribution assembly 10 installed in the anaerobic reactor 7. The water distribution assembly 10 includes a fixing frame 17, a water distribution box 32 fixedly installed on the fixing frame 17, a first motor 12 fixedly installed at the bottom of the anaerobic reactor 7, multiple first water distribution mechanisms 15 and a second water distribution mechanism 16. The water distribution box 32 is equipped with a water guide structure that cooperates with the multiple first water distribution mechanisms 15.

[0059] Reference Figures 4-7 The anaerobic reactor 7 is provided with a water outlet pipe 8 on the top and a water inlet pipe 9 fixedly provided on the bottom. The water inlet pipe 9 is rotatably connected to a water guide pipe 11, which is fixedly connected to a water distribution box 32. The water guide pipe 11 is driven by a transmission belt between the water guide pipe 11 and the first motor 12. The rotation of the driving end of the first motor 12 drives the water guide pipe 11 to rotate through the transmission belt. The rotation of the water guide pipe 11 drives the water distribution box 32 to rotate, thereby driving the fixed frame 17 to rotate. The rotation of the fixed frame 17 drives the first water distribution mechanism 15 and the second water distribution mechanism 16 to rotate.

[0060] A partition 14 is fixedly installed at the bottom of the fixing frame 17, and the partition 14 is rotatably connected to the water pipe 11 to isolate the sludge and water in the anaerobic reactor 7 to prevent the first motor 12 from being affected. The water pipe 11 and the partition 14 are connected by a mechanical seal rotation method. This connection structure is a common existing structure and will not be elaborated here. Its main function is to avoid leakage in the anaerobic reactor 7.

[0061] The water guide structure comprises a plurality of water distribution pipes 18 fixedly installed on the fixed frame 17, each of which is annular in different sizes, a water distribution box 32 is connected with the plurality of water distribution pipes 18 through a communication pipe 27, a plurality of electric control valves matched with the corresponding communication pipes 27 are installed in the water distribution box 32, and a baffle 13 is fixedly installed on the plurality of water distribution pipes 18; each first water distribution mechanism 15 is rotatably installed on the baffle 13;

[0062] The baffle 13 is used to separate the water distribution pipes 18, so that the sewage is on the upper part of the baffle 13, thereby avoiding the situation that the sludge layer is deposited and gathered;

[0063] The anaerobic reactor 7 is provided with a concentration sensor matched with the electric control valve, the concentration sensor senses the sludge concentration in the anaerobic reactor 7, and then controls the communication pipe 27 through the electric control valve, so that the water sprayed by different water distribution pipes 18 is different, thereby disturbing and dispersing the sludge layer in the anaerobic reactor 7, and making the sludge layer more uniformly dispersed.

[0064] Referring to Figures 8-11 The first water distribution mechanism 15 comprises a frame body 23 fixedly installed on the baffle 13, a rotating pipe 28 rotatably installed on the frame body 23, a guide pipe 24 fixedly and communicatively connected to each end of the rotating pipe 28, two guide pipes 24 each being in communication with a corresponding water distribution pipe 18, and a spray head 22 fixedly and communicatively connected to the rotating pipe 28;

[0065] The sewage in the water distribution box 32 enters the guide pipe 24 through the water distribution pipe 18, the sewage in the guide pipe 24 enters the spray head 22 through the rotating pipe 28, and the sewage column is sprayed into the anaerobic reactor 7 through the spray head 22, so that the sewage column contacts the sludge layer in the anaerobic reactor 7, the anaerobic bacteria in the sludge layer decomposes the organic matter in the sewage, and the sewage anaerobic treatment is completed.

[0066] A Venturi tube 31 is fixedly installed in the spray head 22, and a spiral blade 29 is fixedly installed outside the Venturi tube 31 and extends out of the spray head 22;

[0067] The Venturi tube 31 is used to increase the flow rate of the water column sprayed by the spray head 22, thereby increasing the impact force between the sewage and the sludge layer, and the spiral blade 29 is used to make the water column sprayed in the spray head 22 rise in a spiral shape, so that the contact area between the water column and the sludge is larger and the contact is more sufficient, the sewage anaerobic treatment efficiency is higher, and the effect is better.

[0068] A plurality of spray pipes 30 are fixedly and communicatively connected to the bottom of the spray head 22, adjacent two spray heads 22 are connected through a bevel gear set 25, the rotation axis of the bevel gear in the bevel gear set 25 is the same as the rotation axis of the corresponding rotating pipe 28, and an angle adjusting structure matched with the outermost spray head 22 is installed on the anaerobic reactor 7.

[0069] The rotation of the spray head 22 at the outermost layer will drive the spray head 22 at the adjacent layer through the bevel gear set 25, but the rotation directions of the spray heads 22 at the adjacent two layers are opposite, the water column sprayed by the spray head 22 is inclined to spray, which will drive the sludge layer to rotate, and since the angles of the spray heads 22 at the adjacent layers are opposite, the sludge layer will be disturbed to be more uniformly distributed.

[0070] The angle adjusting structure comprises a first fixed ring 19 fixedly installed on the inner wall of the anaerobic reaction kettle 7, a plurality of first elastic expansion rods fixedly installed on the first fixed ring 19, a first rubber ring 20 fixedly installed at the expansion ends of the first elastic expansion rods, a second motor 21 fixedly installed on the anaerobic reaction kettle 7, a cam fixedly installed at the driving end of the second motor 21 and matched with the first rubber ring 20, and a rubber plate 26 fixedly installed on the spray head 22 and matched with the first rubber ring 20 and rotating in an arc shape with the axis of the rotating pipe 28 as the center.

[0071] The rotation of the above-mentioned water distribution box 32 will drive the spray head 22 to make a circumferential rotation around the central axis of the anaerobic reaction kettle 7, at this time, the second motor 21 is started, the driving end of the second motor 21 drives the cam to rotate, the rotation of the cam will press the first rubber ring 20 to move, when the first rubber ring 20 moves to abut against the rubber plate 26, the rubber plate 26 makes a circumferential motion, and the first rubber ring 20 will organize the rubber plate 26 to make a circumferential motion, so that the rubber plate 26 rotates around the rotating pipe 28 as the axis, thereby driving the spray head 22 to rotate around the rotating pipe 28, changing the angle of the spray head 22 on the rotating pipe 28, after the angle is changed, the driving end of the second motor 21 is reversed to separate the first rubber ring 20 from the rubber plate 26, at this time, the angle of the spray head 22 is fixedly unchanged (the damping rotation connection between the rotating pipe 28 and the frame 23 is such that the spray head 22 will not automatically reset after the angle of the spray head 22 is changed).

[0072] Referring to Figures 11-19 , the second water distribution mechanism 16 comprises a fixed pipe 42 fixedly installed on the water distribution box 32, the fixed pipe 42 is communicated with the water distribution box 32, a rotating box 33 is rotatably installed on the fixed pipe 42, a plurality of water outlets are formed at the top of the rotating box 33, a one-way pipe is fixedly installed in each water outlet, a plurality of mixing pipes 34 are fixedly and communicatively connected to the side of the rotating box 33, and a locking structure is installed between each spray head 22 at the innermost layer and the rotating box 33;

[0073] A turbine 43 is rotatably installed in the fixed pipe 42, an axis is fixedly installed at the central axis position of the turbine 43, and the axis is fixedly connected between the rotating box 33;

[0074] The water in the water distribution box 32 enters the rotating box 33 through the fixed pipe 42, and the sewage passes through the turbine 43 during the process. The turbine 43 rotates under the action of water pressure, thereby driving and rotating the box 33 through the shaft. The rotating box 33 has two modes, one is rotation for mixing, and the other is fixed for vertical water distribution. The water column is small, and the sewage and sludge layer are more fully contacted. The switching between the two modes is completed by the locking structure (the angle change of the nozzle 22 switches to the mixing mode, and the angle reset of the nozzle 22 enters the small water column water distribution mode).

[0075] The locking structure includes a bracket fixedly installed on the nozzle 22, a rubber block 38 and a roller 37 fixedly installed on the bracket, a second rubber ring 35 fixedly installed on the rotating box 33 and matched with the rubber block 38, a second fixed ring 39 fixedly installed on the rotating box 33, a plurality of second elastic expansion rods fixedly installed on the second fixed ring 39, and a sliding ring 40 fixedly installed at the extension end of the second elastic expansion rods. The sliding ring 40 is sleeved outside the rotating box 33, and a sliding frame 36 matched with the roller 37 is fixedly installed on the sliding ring 40.

[0076] When the angle of the nozzle 22 changes, the rotation of the nozzle 22 drives the bracket to rotate, which makes the rubber block 38 disengage from the second rubber ring 35. At this time, the roller 37 abuts against the sliding frame 36, and the second rubber ring 35 loses the obstruction of the rubber block 38, so that the turbine 43 drives the rotating box 33 to rotate. Conversely, when the second rubber ring 35 abuts against the rubber block 38, the rotating box 33 is not driven to rotate by the turbine 43, thereby achieving the locking of the rotating box 33.

[0077] The rotating box 33 is provided with a plugging structure matched with the mixing pipe 34 and the water outlet hole;

[0078] The plugging structure includes a plugging plate 45 fixedly installed on the shaft, the plugging plate 45 being smaller in size than the inner diameter of the rotating box 33 and not being attached to the inner top of the rotating box 33. A sliding cover 44 matched with the mixing pipe 34 and the plugging plate 45 is slidingly installed in the rotating box 33. The sliding cover 44 is provided with a water passage hole at the top, and the diameter of the water passage hole is smaller than that of the plugging plate 45. The sliding cover 44 is provided with a water drainage hole matched with the mixing pipe 34 at the side wall. A transmission component is installed between the sliding ring 40 and the sliding cover 44.

[0079] The transmission component includes a linkage gear set 41, which is composed of two racks and a gear. One of the racks is fixedly installed on the sliding ring 40, and the other rack is fixedly installed on the sliding cover 44 through a support. The gear is rotatably installed outside the rotating box 33 and is engaged with the two racks.

[0080] When the rotating box 33 rotates, the roller 37 abuts against the sliding frame 36 at this time, so that the sliding frame 36 drives the sliding ring 40 to move, the sliding ring 40 drives the rack fixedly connected thereto to move, cooperates with the gear, drives the rack on the sliding cover 44 to move reversely, thereby driving the sliding cover 44 to move upward, when the sliding cover 44 moves upward, the top of the sliding cover 44 abuts against the blocking plate 45, at this time, the hydrophobic hole is communicated with the mixing pipe 34, the sewage in the rotating box 33 cannot be discharged from the water outlet on the top of the rotating box 33 through the water passage, but is sprayed out from the mixing pipe 34 through the hydrophobic hole, and a vertical upward water column is formed in the anaerobic reactor 7, at this time, the water column rotates with the rotating box 33, thereby stirring and mixing the sludge layer in the anaerobic reactor 7;

[0081] When the rotating box 33 does not rotate, the sliding ring 40 resets at this time, the hydrophobic hole on the sliding cover 44 is misaligned with the mixing pipe 34, the sewage in the rotating box 33 cannot enter the mixing pipe 34, but is sprayed out from the water outlet on the top of the rotating box 33 through the water passage, since the water outlet has a small diameter, the sprayed water column is thin, which can effectively increase the contact area of the sewage and the sludge layer, so that the sewage and the sludge layer are more fully contacted.

[0082] The fixed pipe 42 is internally provided with a pulse component matched with the hydrophobic hole, the pulse component comprises a support plate fixedly installed on the inner wall of the fixed pipe 42, and a telescopic water baffle 46 fixedly installed on the support plate and matched with the hydrophobic hole.

[0083] When the rotating box 33 rotates, the nozzle 22 is inclined at this time, and a water column is also sprayed out from the mixing pipe 34, but since the telescopic water baffle 46 does not rotate, the telescopic water baffle 46 intermittently blocks the hydrophobic hole, the sewage in the mixing pipe 34 is intermittently sprayed out, so as to form a pulse, which has the purpose of improving the dispersion efficiency of the sludge layer, and can effectively improve the contact frequency of the sewage and the sludge layer, thereby improving the anaerobic treatment efficiency of the sewage.

[0084] The specific operation steps of the device are as follows:

[0085] Firstly, the sewage is discharged into the sedimentation and filtration unit 1 to treat the large-particle suspended matter in the sewage, then the treated sewage enters the anaerobic treatment unit 2 through the water supply and drainage system 6 to treat the organic matter in the sewage by anaerobic bacteria, then the treated sewage enters the microbial treatment unit 3 through the water supply and drainage system 6 to treat the harmful nitrogen and phosphorus substances in the sewage, then the treated sewage enters the chemical treatment unit 4 through the water supply and drainage system 6 to treat the harmful heavy metal substances in the sewage, and finally the sewage enters the acid-base degree adjusting unit 5 through the water supply and drainage system 6 to adjust the pH value of the sewage after a series of treatments;

[0086] In the anaerobic treatment unit 2, the following operations are performed:

[0087] The first mode: the concentration sensor senses that the sludge layer concentration in the anaerobic reactor 7 is uniform, the angle of the spray head 22 is vertical upward, the first motor 12 drives the rotation of the driving end to drive the water guide pipe 11 to rotate, the water guide pipe 11 drives the rotation of the water distribution box 32, thereby driving the rotation of the fixed frame 17, the fixed frame 17 drives the rotation of the water distribution assembly 10, and the water is distributed in rotation, so that the sludge in the anaerobic reactor 7 rotates, and the sludge layer is dispersed;

[0088] The second mode: the concentration sensor senses that the sludge layer concentration in the anaerobic reactor 7 is not uniform, at this time, the angle of the spray head 22 needs to be changed, and the water quantity sprayed by the spray head 22 is controlled by the electric control valve to disturb and mix the sludge layer uniformly;

[0089] Change the angle of the spray head 22: start the second motor 21, the driving end of the second motor 21 rotates to drive the cam to rotate, the cam rotates to press the first rubber ring 20 to move, when the first rubber ring 20 moves to abut against the rubber plate 26, the rubber plate 26 moves in a circular motion, and the first rubber ring 20 drives the rubber plate 26 to move in a circular motion, so that the rubber plate 26 rotates around the rotation pipe 28 as an axis, thereby driving the spray head 22 to rotate around the rotation pipe 28, changing the angle of the spray head 22 on the rotation pipe 28, after the angle is changed, the driving end of the second motor 21 reverses to separate the first rubber ring 20 from the rubber plate 26, at this time, the angle of the spray head 22 is fixed and unchanged;

[0090] When the angle of the spray head 22 is changed, the rotation of the spray head 22 drives the rotation of the support, the rotation of the support drives the rubber block 38 to separate from the second rubber ring 35, at this time, the roller 37 abuts against the sliding frame 36, the second rubber ring 35 is hindered by the rubber block 38, so the turbine 43 drives the rotation of the rotating box 33, conversely, when the second rubber ring 35 abuts against the rubber block 38, the rotating box 33 is not driven to rotate by the turbine 43, and the rotating box 33 is locked;

[0091] When the rotating box 33 rotates, at this time, the roller 37 abuts against the sliding frame 36, the sliding frame 36 drives the sliding ring 40 to move, the sliding ring 40 drives the rack fixedly connected thereto to move, cooperates with the gear, drives the rack on the sliding cover 44 to move reversely, thereby driving the sliding cover 44 to move upward, when the sliding cover 44 moves upward, the top of the sliding cover 44 abuts against the blocking plate 45, at this time, the drain hole is communicated with the mixing pipe 34, the sewage in the rotating box 33 is not discharged from the water outlet on the top of the rotating box 33 through the water inlet, but is sprayed from the mixing pipe 34, and a vertical upward water column is formed in the anaerobic reactor 7, at this time, the water column rotates with the rotating box 33, thereby stirring and mixing the sludge layer in the anaerobic reactor 7;

[0092] When the rotating box 33 does not rotate, the sliding ring 40 is reset, the hydrophobic hole on the sliding cover 44 is misaligned with the mixing pipe 34, and the sewage in the rotating box 33 cannot enter the mixing pipe 34, but is sprayed out from the water outlet on the top of the rotating box 33 through the water passage.

[0093] When the rotating box 33 rotates, the angle of the spray head 22 is inclined, and water column is also sprayed out from the mixing pipe 34, but the telescopic water baffle 46 does not rotate, so the telescopic water baffle 46 intermittently blocks the hydrophobic hole, the sewage in the mixing pipe 34 is intermittently sprayed out, so as to form pulse.

[0094] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
