Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture wastewater treatment, in particular to an aquaculture wastewater advanced treatment integrated device. BACKGROUND

[0002] The integrated treatment device for aquaculture wastewater is mostly designed with fixed process chain integration, and the treatment units (such as grating filtration, anaerobic treatment, aerobic treatment, etc.) are rigidly connected by welding or bolts. For the treatment of different aquaculture wastewater, different treatment units need to be designed according to the ammonia nitrogen and high organic matter load of the aquaculture wastewater. For example, pig wastewater generally presents high ammonia nitrogen (800-2200 mg / L) and high organic matter (CODcr 13000-17000 mg / L) load. When treating pig wastewater, in addition to anaerobic and aerobic treatment units, a strengthened anoxic unit is needed to achieve nitrification and denitrification for nitrogen removal. For example, chicken wastewater needs to be set with high-efficiency solid-liquid separation and deep disinfection modules due to high concentration of suspended solids and pathogenic bacteria. For example, fish wastewater has low organic matter concentration (CODcr 500-2000 mg / L) but high dissolved oxygen demand, and there are residual antibiotics and feed additives, so an oxidation unit is needed to degrade antibiotics and additives, and an ecological wetland unit is also needed to absorb nitrogen and phosphorus by using aquatic plants in the ecological wetland unit.

[0003] The treatment devices of the prior art are all designed for specific wastewater conditions. For example, the pig breeding wastewater advanced treatment integrated device disclosed in Chinese patent CN117185589B has anoxic treatment tank, aerobic treatment tank, flocculation sedimentation tank, ultraviolet disinfection tank, filtration and adsorption tank, and ecological wetland tank arranged in sequence on the two liquid outlets of the anaerobic treatment unit according to the water flow direction. This device realizes the effects of short-cut nitrification and denitrification, simultaneous nitrification and denitrification, and biological phosphorus removal, and makes the finally discharged wastewater meet the standards. For example, the livestock and poultry breeding wastewater integrated treatment device disclosed in Chinese patent CN206512062U has a red mud adsorption device for wastewater with high heavy metal content, which uses active components such as iron oxide and calcium oxide to treat heavy metals in wastewater.

[0004] In the above-mentioned wastewater advanced treatment devices, although the finally discharged wastewater can meet the standards, each treatment device can only treat specific aquaculture wastewater, and cannot dynamically adjust the process chain according to the differences in breeding types. To solve this problem, the applicant has invented an aquaculture wastewater advanced treatment integrated device which can adjust the treatment process according to the specific conditions of the aquaculture wastewater.

[0044] Referring to Figures 1-11 , a preferred embodiment provided by the present application is shown.

[0045] Embodiment 1: an integrated device for deep treatment of aquaculture wastewater, as shown in Figures 1-4 , comprising a vertically installed pretreatment unit, the function of the pretreatment unit is to filter large particle impurities in aquaculture wastewater, the embodiment adopts a centrifugal method to achieve the filtering effect. As shown in Figure 1 , the pretreatment unit mainly consists of a pressurizing cylinder 1, a separation cylinder 8, a screw 20 and a driving mechanism, the pressurizing cylinder 1 and the separation cylinder 8 are vertically installed, the separation cylinder 8 is located in the pressurizing cylinder 1, a plurality of filter holes 9 are opened on the side wall of the separation cylinder 8, the side wall of the separation cylinder 8 is in sealing rotary contact with the bottom surface of the pressurizing cylinder 1, the bottom of the separation cylinder 8 is connected with a wastewater pipe 12, the wastewater pipe 12 is taken as a part of the device in the embodiment, in order to make the separation cylinder 8 rotate normally, the wastewater pipe 12 is set in rotary connection with the initial pipeline in the embodiment, if the initial pipeline does not have a pressurizing device, paddle blades can also be arranged in the wastewater pipe 12 or the separation cylinder 8, so that the wastewater in the initial pipeline can be pressurized into the separation cylinder 8 when the separation cylinder 8 rotates. The screw 20 is fixedly installed on the separation cylinder 8, so that the screw 20 can pressurize the filtered aquaculture wastewater into the anaerobic treatment unit.

[0046] In the embodiment, the driving mechanism, as shown in Figure 1 , mainly consists of a driving motor 10, two rotating wheels 11 and a power transmission belt 13; the driving motor 10 is fixedly installed at the bottom of the pressurizing cylinder, the two rotating wheels 11 are respectively sleeved on the output end of the driving motor 10 and the wastewater pipe 12, and the power transmission belt 13 is sleeved on the two rotating wheels 11 at the same time.

[0047] The anaerobic treatment unit of the embodiment mainly consists of an anaerobic treatment tank 3, a reflux tank 2, a three-phase separator 4, a water outlet weir 6 and a gas permeation pipe 5. The bottom of the anaerobic treatment tank 3 is connected with the top of the pressurizing cylinder 1, so that the pretreated wastewater enters the anaerobic treatment tank 3 from the bottom of the anaerobic treatment tank 3 under the action of the pressurizing of the screw 20 and reacts with the sludge bed zone in the anaerobic treatment tank 3. In order to enable the wastewater to fully perform the anaerobic reaction, the reflux tank 2 is fixedly sleeved on the outer side wall of the anaerobic treatment tank 3 in the embodiment, the bottom of the reflux tank 2 is connected with the bottom of the anaerobic treatment tank 3 through a pipeline, and the top of the reflux tank 2 and the top of the anaerobic treatment tank 3 are open and have flush top surfaces. In this way, part of the reacted wastewater enters the reflux tank 2. In order to enable part of the wastewater to flow out of the anaerobic treatment unit, the water outlet weir 6 is fixedly sleeved on the top of the reflux tank 2 in the embodiment, the three-phase separator 4 is a separator with an open bottom and a reverse conical shape, the bottom surface of the three-phase separator 4 is in contact with the water outlet weir 6 and has a gap, and the gas permeation pipe 5 is fixedly connected with the top of the three-phase separator 4. In this way, the generated biogas is discharged through the gas permeation pipe 5, and the anaerobically treated wastewater enters the pipeline through the water outlet weir 6.

[0048] In order to improve the wastewater purification efficiency, modular treatment process chains are arranged around the pressurizing cylinder 1, and four groups of the modular treatment process chains are arranged in the embodiment in the manner of Figure 4 Modular treatment process chains are composed of multiple treatment devices, and, as shown in Figure 1 For example, the breeding wastewater of a pig farm is taken as an example, an anoxic treatment unit 19, an aerobic treatment unit 18, a flocculation and sedimentation unit 17, an ultraviolet disinfection unit 16, a filtration and adsorption unit 15 and an ecological wetland unit 14 are arranged, and the six treatment units are sequentially installed from top to bottom. In the present application, each treatment unit adopts the prior art, and the specific internal structure is not described in detail, and the staff only needs to select different treatment units according to the specific conditions of the breeding wastewater. As shown in Figure 3 The liquid inlet end (close to the top) and the liquid outlet end (located at the bottom) of the treatment unit are connected with a flow guide mechanism. The pipeline mainly consists of one main pipe 7, six liquid inlet pipes 24, six external connection pipes 30 and six liquid outlet pipes 32. The top end of the main pipe 7 is connected with the water outlet weir 6, and the bottom end of the main pipe 7 is detachably connected with the liquid inlet pipe 24 corresponding to the aerobic treatment unit 18. The liquid outlet pipe 32 corresponding to the aerobic treatment unit 18 is detachably connected with the liquid inlet pipe 24 corresponding to the next-stage treatment unit, so that the treatment units can be sequentially connected. In order to enable the equipment to be overhauled and the internal purification substances to be replaced without stopping operation, the external connection pipe 30 is fixedly installed between the two flow guide mechanisms.

[0049] As shown in Figure 3As shown, the flow guiding mechanism mainly consists of a spherical shell 28 and a sphere 33. The sphere 33 is located inside the spherical shell 28, and an L-shaped channel 39 is opened inside the sphere 33. The flow guiding mechanism is connected to the liquid inlet end of the treatment unit. The other two ends of its spherical shell 28 are connected to the liquid inlet pipe 24 and the external pipe 30, respectively. One end of the L-shaped channel 39 is always connected to the liquid inlet pipe 24, and the other end can be connected to the liquid inlet end of the treatment unit and the external pipe 30, respectively, when the sphere 33 rotates. The flow guiding mechanism is connected to the liquid outlet end of the treatment unit. The other two ends of its spherical shell 28 are connected to the liquid outlet pipe 32 and the external pipe 30, respectively. One end of the L-shaped channel 39 is always connected to the liquid outlet pipe 32, and the other end can be connected to the liquid inlet end of the treatment unit and the external pipe 30, respectively, when the sphere 33 rotates. When the treatment unit is needed to purify wastewater, the L-shaped channels 39 of the two flow guiding mechanisms are connected to the liquid inlet end and the liquid outlet end of the treatment unit, respectively. Figure 3 (as shown in the diagram). When the treatment unit needs maintenance or internal purification material needs to be replaced, simply connect the L-shaped channels 39 of the two flow guiding mechanisms to the external pipe 30. In this way, the wastewater flows directly from the inlet pipe 24 through the external pipe 30 to the outlet pipe 32, and then directly enters the next stage of the treatment unit.

[0050] To enable simultaneous reversal of the L-shaped channels 39 of the two flow guiding mechanisms, a drive unit is provided between the two flow guiding mechanisms in this embodiment. The drive unit mainly consists of a servo motor 35, a transmission shaft 38, two bevel gears 34, two bevel gears 29, and two transmission gears 37. The shafts of the two bevel gears 34 are fixedly connected to the ends of the transmission shaft 38 and the output end of the servo motor 35, respectively. The two bevel gears 34 mesh with the two bevel gears 29, respectively. The two transmission gears 37 are fixedly sleeved on the output shafts of the transmission shaft 38 and the servo motor 35, respectively, and are also meshed. In this way, when the servo motor 35 rotates, the direction of the L-shaped channels 39 of the two flow guiding mechanisms can be adjusted simultaneously. To protect the drive unit, a waterproof box 31 is fixedly installed on the outer wall of each processing unit in this embodiment. The entire drive unit is housed in the waterproof box 31, and the central shafts of the two bevel gears 29 are in sealed contact with the waterproof box 31.

[0051] Regarding the drive unit, it should be emphasized that, regardless of whether electric or manual adjustment is used, as long as a single drive unit can simultaneously rotate the spheres 33 of the two flow guiding mechanisms and achieve the effect of connecting the L-shaped channel 39 to the external pipe 30 or the processing unit at the same time, such a drive unit structure is within the protection scope of this application.

[0052] To ensure more stable installation of each treatment unit, this embodiment also includes a slider 36 with a protruding end on the aerobic treatment unit 18. A groove (not shown in the figure) matching the size of the slider 36 is formed on the outer wall of the pressurized cylinder 1. There is a certain amount of damping between the slider 36 and the groove. The bottom of the groove allows the slider 36 to be inserted. When the slider 36 moves upward, it is subject to a limiting effect. Figure 1 (As shown).

[0053] In this embodiment, if the quality of the aquaculture wastewater changes significantly and requires replacement with a different treatment unit, the connection between the inlet pipe 24 and the outlet pipe 32 can be directly removed, and the entire unit can be replaced. Figure 3 This part can be replaced.

[0054] In this embodiment, the connection method between the inlet pipe 24 and the main pipe 7 / outlet pipe 32 is as follows: Figure 2 As shown, an annular groove 27 is formed on the outer wall of the connection between the outlet pipe 32 and the main pipe 7. A spring 21 and a limiting ring 22 are sleeved in the annular groove 27. The two ends of the flow-through spring 21 are fixedly connected to the end of the annular groove 27 and the limiting ring 22, respectively. Multiple through grooves 26 are also formed on the side wall of the connection between the main pipe 7 and the outlet pipe 32. Each through groove 26 is provided with a limiting ball 25. The outer diameter of the connection of the inlet pipe 24 matches the inner diameter of the connection of the outlet pipe 32. A limiting groove 23 corresponding to the through groove 26 is formed on the outer wall of the inlet pipe 24. When the inlet pipe 24 is connected to the outlet pipe 32, the limiting ball 25 is simultaneously located in the through groove 26 and the limiting groove 23, and the inner wall of the limiting ring 22 contacts the limiting ball 25. However, when disassembly is required, the staff should hold the limiting ring 22 and lift it upward to expose the limiting ball 25, and then pull the inlet pipe 24 downward. The limiting ball 25 will leave the limiting groove 23, and the inlet pipe 24 can be removed.

[0055] Working principle: when the device is needed, install the pressurized cylinder 1 in the appropriate position, let the waste water pipe 12 connect with the initial pipe, according to the content of ammonia nitrogen, CODcr and other content in aquaculture wastewater to determine which processing unit to use, after selection, install in turn, let the corresponding liquid inlet pipe 24 of each processing unit connect with the liquid outlet pipe 32 of the previous processing unit. The first stage processing unit is connected with the main pipe 7. In normal equipment operation, the driving motor 10 drives the rotating wheel 11 to rotate, and the waste water pipe 12 is driven to rotate through the power transmission belt 13, and the waste water pipe 12 drives the separation cylinder 8 to rotate, at this time, the waste water in the separation cylinder 8 is thrown out to the pressurized cylinder 1 under the action of centrifugal force. Since the spiral device 20 is also rotating at the same time, the spiral device 20 pressurizes the filtered waste water into the anaerobic treatment unit, and the treated waste water enters the liquid inlet pipe 24 through the main pipe 7, and then enters the treatment unit through the L-shaped channel 39, and after the treatment, it enters the liquid outlet pipe 32 through another L-shaped channel 39 of the flow guide mechanism, and then enters the next stage processing unit. If it is necessary to overhaul or replace the purification material in the processing unit, the staff rotates the servo motor 35, which drives the bevel gear 1 and the bevel gear 2 29 to rotate, thereby driving the ball 33 to rotate, and the two flow guide mechanisms are synchronous, so that the free end of the L-shaped channel 39 is in communication with the external pipe 30 at the same time. In this way, after the aquaculture wastewater flows through the liquid inlet pipe 1, it directly flows into the liquid outlet pipe 32 through the external pipe 30, and then enters the next stage processing unit.

[0056] Example 2: an integrated aquaculture wastewater advanced treatment device, the main difference between this embodiment and example 1 is that the disassembly position of the treatment device is different, in order to reduce the detachable parts, this embodiment is to form a whole pipeline with the liquid inlet pipe 1, the liquid outlet pipe 2, the main pipe 7 and the flow guide mechanism, the liquid inlet end and the liquid outlet end of the processing unit are connected with the spherical shell 28 of the two flow guide mechanisms in a detachable way, the specific connection way is the same as the connection way between the liquid inlet pipe 1 and the liquid outlet pipe 2 in example 1. At the same time, the waterproof box 31 is fixedly installed on the external pipe 30, in addition, the slider 36 is cancelled. In this way, the staff only needs to take down the processing unit when disassembling.

[0057] In the design of the product, the internal structure and size of each processing unit are determined according to the actual situation, only need to match the size of the liquid inlet end and the liquid outlet end of the processing unit with the port size of the flow guide mechanism, then the installation can be carried out smoothly.

[0058] Example 3: an integrated aquaculture wastewater advanced treatment device, the main difference between this embodiment and example 1 is that the connection way of the processing device and the pipeline is different. As Figures 8-10As shown, in this embodiment, the pipeline is composed of a main pipe two 40, a plurality of connecting pipes one 43 and a plurality of connecting pipes two 49. The connecting pipes one 43 and the connecting pipes two 49 are connected perpendicularly to the main pipe two 40, and the connecting pipes one 43 and the connecting pipes two 49 are arranged alternately. The cross section of the main pipe two 40 in this embodiment is rectangular. A sealing unit is installed at the connection between the connecting pipes one 43 and the connecting pipes two 49 and the main pipe two 40; the sealing unit is mainly composed of a spring two 45 and a sealing plate 48, one end of the spring two 45 is fixedly connected to the inner wall of the connecting pipes one 43 or the connecting pipes two 49, and the other end is fixedly connected to the sealing plate 48; when the treatment device is not installed, the sealing plate 48 is attached to the end of the connecting pipes one 43 or the connecting pipes two 49 under the action of the spring two 45 and realizes sealing.

[0059] In addition, as Figure 9 shown, a baffle 47 is also slidably arranged on the outer side wall of the connecting pipes one 43, the top surface of the baffle 47 matches the inner diameter of the main pipe two 40, and is fixedly connected to the bottom of the sealing plate 48. As Figure 6 shown, when the sealing plate 48 is attached to the inner wall of the main pipe two 40, most of the area of the baffle 47 is inside the main pipe two 40, and the main pipe two 40 is blocked.

[0060] The entire treatment device of this embodiment is also different from that of embodiment 1, the treatment device of this embodiment is mainly composed of a treatment unit, a liquid inlet pipe two 42 and a liquid outlet pipe two 41, the liquid inlet pipe two 42 and the liquid outlet pipe two 41 are respectively fixedly connected to the liquid inlet end and the liquid outlet end of the treatment unit, and the connection between the liquid inlet pipe two 42 and the liquid outlet pipe two 41 matches the connection between the connecting pipes one 43 and the connecting pipes two 49. As Figure 6 shown, in order to stably install the treatment device, matching threads are arranged on the connecting pipes one 43, the connecting pipes two 49, the liquid inlet pipe two 42 and the liquid outlet pipe two 41 in this embodiment, a fixing ring 44 is arranged on the threads, the fixing ring 44 is sleeved on the threaded section of the connecting pipes one 43 and the connecting pipes two 49, when the liquid inlet pipe two 42 and the liquid outlet pipe two 41 are connected to the connecting pipes one 43 and the connecting pipes two 49 respectively, only need to rotate the fixing ring 44 to the position of the connection of the pipes, and then the fixing can be realized. Meanwhile, a jacking rod 46 is fixedly installed at the end of the liquid inlet pipe two 42 and the liquid outlet pipe two 41, when the liquid inlet pipe two 42 and the liquid outlet pipe two 41 are installed, the jacking rod 46 can just push the sealing plate 48 to attach to the inner wall of the main pipe two 40 (as Figure 6 and Figure 7 shown), at this time, the baffle 47 also just blocks the main pipe two 40, so that the aquaculture wastewater can only flow into the installed treatment unit.

[0061] Since the distance between the connecting pipe one 43 and the connecting pipe two 49 is fixed, in order to enable different processing units to be installed on the connecting pipe one 43 and the connecting pipe two 49, the vertical section of the liquid outlet pipe two 41 is arranged as an extendable pipe.

[0062] In order to enable the main pipe two 40 to be more stable, the fixed frame 50 is fixedly installed on the outer side wall of the pressurized cylinder body 1, and the fixed frame 50 is fixedly sleeved on the main pipe two 40 in a sleeve ring manner.

[0063] Compared with the scheme of the embodiment 1, the embodiment can automatically enable the wastewater to enter the processing unit by installing the processing device, and a flow guide mechanism does not need to be designed separately, and when the processing device is removed, the aquaculture wastewater can also normally flow into the next stage processing unit.

[0064] It needs to be highlighted that the entire processing device can be detachably installed on the pipeline according to the requirements, and when the internal purification substances are overhauled or replaced, the equipment does not need to be shut down, and such a pipeline and the processing device are within the protection scope of the application.

[0065] Working principle: when the processing device is installed on the connecting pipe one 43 and the connecting pipe two 49, the liquid inlet pipe two 42 and the liquid outlet pipe two 41 are connected with the two connecting pipes, the fixed ring 44 is sleeved on the two threaded sections, the top rod 46 is used to top the sealing plate 48 to the inner wall of the main pipe two 40, and the baffle 47 is used to block the main pipe two 40, at this time, the aquaculture wastewater enters the processing unit, and then flows out from the liquid outlet pipe two 41. When the processing unit needs to be dynamically adjusted, the fixed ring 44 is loosened, and then the processing device is removed, the sealing plate 48 is blocked by the spring two 45, at this time, the baffle 47 is moved to the outside of the main pipe two 40, and the aquaculture wastewater directly flows into the next stage processing unit.

[0066] The above only describes the preferred embodiments of the application, and is not used to limit the application, and any modification, equivalent replacement and improvement within the spirit and principle of the application should be included in the protection scope of the application.
