Description

Technical Field

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

[0002] Wastewater refers to water bodies that have lost their original functions and are discharged during human activities. They contain pollutants (such as chemicals, organic matter, heavy metals, etc.) and need to be treated before they can be safely discharged or reused. Their sources cover domestic, industrial, agricultural and other fields. According to the degree of pollution, they can be divided into "black water" (high pollution) and "grey water" (low pollution). Wastewater mainly includes industrial wastewater, domestic wastewater and construction wastewater. Due to the large number of pollutants in wastewater, it cannot be discharged directly and needs to be treated using wastewater pretreatment equipment. However, the structure of this pretreatment equipment is usually too simple. Although it can play a certain filtering and clarification role, this pretreatment equipment will continue to produce suspended matter or sediment in the subsequent reaction and treatment process, resulting in floating matter, sediment and suspended matter in the effluent, affecting the normal wastewater discharge and subsequent possible further purification operations, resulting in low work and operation efficiency, and easily leading to uneven and incomplete treatment.

[0003] According to a continuous treatment system for domestic sewage with the announcement number CN211284087U, it includes a treatment tank body, which is divided into several sub-tanks. Adjacent sub-tanks are connected through overflow holes. The sub-tanks include at least a physical separation tank, an anaerobic treatment tank and an aerobic treatment tank arranged in sequence. A glass fiber reinforced plastic cylinder body is provided in the physical separation tank and the aerobic treatment tank. The upper part of the glass fiber reinforced plastic cylinder body is open and faces the overflow hole of the upper tank body. At the same time, a surface seal is provided on the side of the glass fiber reinforced plastic cylinder body through a multi-layer nylon polytetrafluoroethylene filter screen. The open side of the closed tank is provided with a filter grid assembly in the FRP cylinder of the physical separation tank, and a filler support is provided in the FRP cylinder of the aerobic treatment tank. During the physical / chemical / biological treatment of sewage, the sediment and suspended matter are filtered multiple times. The treated sewage can be discharged directly, used for irrigation, or sent to a domestic sewage treatment plant for further purification. When the water is sent to the water recovery pipeline of the domestic sewage treatment plant, the operating burden of related equipment can be effectively reduced to improve its operating stability, reliability and service life.

[0004] Regarding the above-mentioned related schemes, a submersible mixer is used to mix anaerobic sludge and wastewater so that the microorganisms in the anaerobic sludge can contact and degrade the pollutants. However, the submersible mixer can only form a circulation on the horizontal plane, resulting in a decrease in vertical mixing efficiency, insufficient sludge-water contact area, and the existence of a mixing dead zone. In addition, the fixed submersible mixer needs to be equipped with multiple independent motor drives, which increases the energy consumption cost. In addition, sludge is easily precipitated at the bottom of the anaerobic treatment tank. The sludge that has been precipitated for a long time will occupy the effective volume of the anaerobic treatment tank, reduce the contact area between the wastewater and the microorganisms, and lead to a decrease in the degradation rate of organic matter. Moreover, the sludge is difficult to separate after being muddied and compacted, which further hinders the decomposition of pollutants and easily deteriorates the water quality. At the same time, the long-term precipitation of sludge can easily lead to uneven flow in the anaerobic treatment tank, forming a dead zone or short flow, and reducing the utilization rate of the hydraulic retention time.

[0015] Preferably, guide grooves are symmetrically provided on the surface of the rotating shaft, and guide blocks forming a sliding structure with the guide grooves are symmetrically provided on the inner surface of the gear.

[0016] Preferably, a filter grid group and three nylon polytetrafluoroethylene filter screens are sequentially arranged on the inner side of the glass cylinder from back to front, the two perforated glass cylinders are staggered, and the filler bracket inside the perforated glass cylinder is filled with a composite filler.

[0017] A continuous wastewater treatment method comprises the following steps:

[0018] S1, coarsely filter the wastewater through the solid-liquid separation structure connected to the front end of the physical separation tank;

[0019] S2, then the water that has been coarsely filtered in the solid-liquid separation structure is fed into the glass cylinder through the liquid inlet at one end of the physical separation tank, and the water that has been finely filtered through the filter grid group and the three-layer nylon polytetrafluoroethylene filter in the glass cylinder enters the physical separation tank;

[0020] S3. Simultaneously, the physical separation tank is continuously aerated by the aeration assembly at the bottom of the physical separation tank to oxygenate the water, so that the separated water in the physical separation tank undergoes an initial aerobic pre-reaction;

[0021] S4. The treated water enters the anaerobic treatment tank and flocculation sedimentation tank in sequence through the overflow tank for corresponding treatment. The anaerobic sludge and water are fully stirred and mixed by the displacement mechanism, and the precipitated sludge is turned over by the anti-caking mechanism to prevent caking.

[0022] S5. The water then flows through the overflow trough into the perforated glass cylinder at the top of the first aerobic treatment tank. When the water flows through the composite filler 1 in the filler holder, it fully contacts and degrades the microbial film attached to the composite filler 1. The water then flows through the overflow trough between the first and second aerobic treatment tanks into the perforated glass cylinder at the top of the second aerobic treatment tank. When the water flows through the composite filler 2 in the filler holder, it again fully contacts and degrades the microbial film attached to the composite filler 2. Both aerobic tanks are equipped with adjustable aeration assemblies.

[0023] S6. The final treated water is discharged from the outlet of the second aerobic treatment tank in compliance with the standards.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention drives a multi-mechanism linkage system through a single motor, drives the displacement plate to move back and forth laterally through a threaded rod, and cooperates with the transmission of the toothed disc-rack-guide rod one to realize the three-dimensional compound movement of the stirring rod, that is, lateral displacement + rotation + longitudinal movement, so that the mixing plate forms a dynamic stirring path, effectively eliminating the stirring dead zone and improving the mixing efficiency; the transmission of the gear-toothed plate-guide rod two realizes the rotation and lateral movement of the flip plate, and the symmetrically spaced flip plates slowly flip the bottom sludge in a low-resistance mode, effectively preventing caking and improving the microbial activity retention rate; the wastewater continuous treatment equipment has a streamlined and efficient structure, and a single motor drive replaces multiple power sources, significantly reducing system complexity and energy consumption, and replacing electronic collaborative control with mechanical linkage can eliminate the risk of multi-motor timing error, thereby enhancing operational reliability, while extending service life and reducing maintenance costs.

[0025] 1. When the drive motor of this continuous wastewater treatment equipment is working, the output end of the drive motor drives the threaded rod to reciprocate forward and reverse, causing the displacement plate to make a lateral reciprocating movement, while causing the gear disk and the support shaft to rotate together. Under the action of the pulley group, the symmetrically arranged guide cylinder 1, the stirring rod, and the mixing plate are rotated together through the support shaft, thereby facilitating large-scale rapid mixing of wastewater and anaerobic sludge through the lateral displacement and rotation of the stirring rod and mixing plate. During the rotation process, the stirring rod and the mixing plate make a longitudinal reciprocating movement through the cooperation of the guide member 1 and the guide rod 1, thereby achieving full coverage mixing in the three-dimensional space of the pool. By dynamically adjusting the stirring path, the dead zone problem caused by traditional fixed stirring is reduced, the mixing efficiency and effect of anaerobic sludge and wastewater are improved, and the effective contact area is greatly increased to ensure efficient contact and degradation of microorganisms and pollutants. Compared with traditional multi-motor systems, energy consumption is reduced and equipment operation noise is reduced. In addition, the modular design shortens the replacement time of key components and reduces annual maintenance costs.

[0026] 2. In the continuous wastewater treatment equipment, when the support frame and the flip plate move horizontally back and forth along with the guide cylinder 2, the gear, the rotating shaft and the flip plate rotate together, thereby realizing the slow flipping of the settled sludge, preventing the long-term sedimentation and compaction of the sludge at the bottom from affecting the treatment effect and efficiency of domestic wastewater. The disc drives the rotating shaft and the flip plate to move horizontally left and right while rotating through the cooperation of the limit member 2 and the guide rod 2, thereby realizing the comprehensive and slow flipping of the settled sludge, so as to improve the flipping efficiency and effect, thereby ensuring the treatment effect of domestic wastewater, and the symmetrically arranged multiple flip plates are arranged at intervals, so that the resistance during flipping can be reduced, energy consumption can be saved, and movement and flipping can be more labor-saving. In addition, the horizontal front and back and left and right displacement and rotation of the flip plate can also achieve the purpose of rapid mixing of wastewater and anaerobic sludge.

[0027] 3. The present invention drives the displacement plate and the support frame to move horizontally back and forth through a single drive motor, and the horizontal back and forth movement of the displacement plate and the support frame causes the toothed disc and the stirring rod, the gear and the rotating shaft to rotate back and forth, the stirring rod to move longitudinally back and forth, and the flip plate to move horizontally left and right, so that the anaerobic sludge and wastewater can be fully mixed and the precipitated sludge can be slowly flipped, thereby improving the mixing uniformity, and preventing the precipitated sludge from clumping through slow flipping, maintaining the activity of microorganisms, and having a streamlined and efficient structure, and significantly reducing the system complexity and energy consumption. Mechanical linkage replaces electronic collaborative control, which can eliminate the risk of multi-motor timing errors, enhance operational reliability, extend service life, and reduce maintenance costs.

[0040] A water inlet is provided at the top of one side of the physical separation tank 1, and an ultrasonic flowmeter and a multi-parameter water quality analyzer are installed at the water inlet end to collect data such as water volume, water temperature, flow rate, ORP, and DO in real time. The anaerobic treatment tank 2 is equipped with a volatile fatty acid sensor and a biogas composition analyzer. Aerobic tanks 4 / 5 are equipped with MLSS and nitrate nitrogen online monitoring modules.

A water outlet is provided at the top of one side of the second aerobic treatment tank 5. Aerobic tanks 4 / 5 use microporous aerators, and the supporting photovoltaic energy storage system reduces the consumption of purchased electricity by 30%.

[0041] See Figure 1 and Figure 2It can be seen that the front end of the physical separation tank 1 is connected to a solid-liquid separation structure for treating wastewater, and the water body that has been coarsely filtered in the solid-liquid separation structure is fed into the glass cylinder 8 through the liquid inlet at one end of the physical separation tank 1, so that the water body that has been finely filtered by the filter grid group 9 and the three-layer nylon polytetrafluoroethylene filter screen 14 in the glass cylinder 8 enters the physical separation tank 1, and at the same time, the physical separation tank 1 is continuously aerated by the aeration assembly 12 at the bottom of the physical separation tank 1 to oxygenate the water body, thereby performing initial aeration on the water body after separation in the physical separation tank 1. After aerobic pre-reaction, the treated water enters the anaerobic treatment tank 2 and the flocculation sedimentation tank 3 in sequence through the overflow trough 11, and then enters the two-stage aerobic treatment unit in an upflow manner. The perforated glass cylinder 10 at the top of the first aerobic treatment tank 4 and the second aerobic treatment tank 5, when the water flows through the combined filler 1 / 2 in the filler bracket, it fully contacts and degrades with the microbial film attached to the combined filler 1 / 2. Both the two-stage aerobic tanks are equipped with an adjustable aeration assembly 12. Finally, the treated water is discharged from the outlet of the second aerobic treatment tank 5 in compliance with the standards, thereby completing the continuous treatment of wastewater.

[0042] See Figures 1-8 It can be seen that a displacement mechanism 6 is provided on the inner side of the anaerobic treatment tank 2. The displacement mechanism 6 includes a displacement plate 603 movably connected to the anaerobic treatment tank 2, a movable frame 611 and a rack 606 welded to the anaerobic treatment tank 2, and the inner side of the movable frame 611 is connected to a stirring rod 609 through a bearing, and a mixing plate 610 is provided at an equal angle on the outer side of the stirring rod 609. The two ends of the stirring rod 609 are respectively slidably connected to a guide cylinder 1 607 and a guide cylinder 2 608. One side of the top of the displacement plate 603 is rotatably connected to a support shaft 604 through a bearing. The outer surface of the support shaft 604 is provided with a gear disc 605 meshing with the rack 606, and the gear disc 605 is used to drive the support shaft 604 to rotate. A pulley group 61 is connected between the support shaft 604 and the guide cylinder 1 607 and between the two guide cylinders 1 607. 4, and the pulley group 614 is used to make the guide cylinder 607 rotate synchronously with the support shaft 604, and the guide cylinder 607 is rotatably connected to the displacement plate 603 through a bearing. The interior of the anaerobic treatment tank 2 is provided with a guide rod 613 on both sides of the movable frame 611, and a limit member 612 is provided on both sides of the movable frame 611. The limit member 612 and the anaerobic treatment tank 2 form a sliding structure through the guide rod 613, and the guide rod 613 is set to a wavy structure. The guide rod 613 is used to make the movable frame 611 perform longitudinal reciprocating motion. A driving motor 601 is installed in the mounting frame at the front end of the anaerobic treatment tank 2. The output end of the driving motor 601 is connected to a threaded rod 602 rotatably connected to the anaerobic treatment tank 2 through a bearing through a coupling, and the threaded rod 602 is threadedly connected to the displacement plate 603;

[0043] See Figures 1-8It can be seen that when the driving motor 601 is working, the output end of the driving motor 601 drives the threaded rod 602 to reciprocate forward and reverse. Since the threaded rod 602 is threadedly connected to the displacement plate 603, the displacement plate 603 makes a horizontal reciprocating movement. Since the toothed disc 605 is meshed with the rack 606, the toothed disc 605 and the support shaft 604 rotate together, and under the action of the pulley group 614, the symmetrically arranged guide cylinder 607 and the stirring rod 609 and the mixing plate 610 are rotated together through the support shaft 604, thereby facilitating the large-scale rapid mixing of wastewater and anaerobic sludge by the lateral displacement and rotation of the stirring rod 609 and the mixing plate 610. Pool 2 is slidably connected by guide piece 1 and guide rod 1 613, and the stirring rod 609 is slidably connected to guide cylinder 1 607 and guide cylinder 2 608, so that the stirring rod 609 and the mixing plate 610 make longitudinal reciprocating movements during the rotation, thereby achieving full coverage stirring in the three-dimensional space of the pool. By dynamically adjusting the stirring path, the dead zone problem caused by traditional fixed stirring is reduced, the mixing efficiency and effect of anaerobic sludge and wastewater are improved, and the effective contact area is greatly increased to ensure efficient contact and degradation of microorganisms and pollutants. Compared with traditional multi-motor systems, energy consumption is reduced and equipment operation noise is reduced. In addition, the modular design shortens the replacement time of key components and reduces annual maintenance costs.

[0044] See Figure 1 、 Figure 2 and Figure 7-Figure 9 It can be seen that the inner side of the anaerobic treatment tank 2 is provided with an anti-knotting plate mechanism 7 at the bottom end of the guide cylinder 2 608. The anti-knotting plate mechanism 7 includes a support frame 701 connected to the guide cylinder 2 608 through a bearing, a tooth plate member 705 welded to the anaerobic treatment tank 2, and a guide rod 2 708. The inner side of the support frame 701 is movably connected with a rotating shaft 702. The surface of the rotating shaft 702 is symmetrically provided with a flip plate 703. The surface of the rotating shaft 702 is located on both sides of the support frame 701. Gears 704 meshing with the tooth plate member 705 are provided. The tooth plate member 705 consists of a tooth plate and a side guard bar. The side guard bar can limit the gear 704 so that it is always in contact with the tooth plate member 7 05 is in a meshing state, with discs 706 provided on both sides of the rotating shaft 702, and a second limiter 707 which forms a sliding structure with a second guide rod 708 provided on the side of the disc 706 away from the gear 704, and the second guide rod 708 is used to make the flip plate 703 move horizontally left and right during the process of horizontal forward and backward movement and rotation, and guide grooves 709 are symmetrically provided on the surface of the rotating shaft 702, and guide blocks 710 which form a sliding structure with the guide grooves 709 are symmetrically provided on the inner surface of the gear 704, so that the position and operating state of the gear 704 will not be affected when the rotating shaft 702 moves horizontally left and right;

[0045] See Figure 1 、 Figure 2 and Figure 7-Figure 9 It can be seen that since the symmetrically arranged guide cylinder 2 608 is connected to the support frame 701 through a bearing, the support frame 701 and the flip plate 703 move horizontally forward and backward together with the guide cylinder 2 608. Since the gear 704 is meshed with the tooth plate 705, the gear 704, the rotating shaft 702 and the flip plate 703 rotate together, thereby realizing the slow flipping of the settled sludge, preventing the long-term sedimentation and hardening of the sludge at the bottom from affecting the treatment effect and efficiency of domestic wastewater. Since the disc 706 is connected to the anaerobic treatment tank 2, the gear 704 and the rotating shaft 702 are respectively connected by the limiter 2 707, the guide rod 2 708, and the guide block 71 0. The guide groove 709 is slidably connected, and the rotating shaft 702 is connected to the disc 706 through a bearing, so that the disc 706 drives the rotating shaft 702 and the flip plate 703 to move horizontally in the left and right directions while rotating, thereby achieving comprehensive and slow flipping of the settled sludge, so as to improve the flipping efficiency and effect, thereby ensuring the treatment effect of domestic wastewater, and the symmetrically arranged multiple flip plates 703 are arranged at intervals, so that the resistance during flipping can be reduced, energy consumption is saved, and movement and flipping are more labor-saving. In addition, the lateral front and back and left and right displacements and rotations of the flip plate 703 can also achieve the purpose of quickly mixing the wastewater and anaerobic sludge.

[0046] See Figure 1-Figure 3 It can be seen that a support rod 13 that passes through the displacement plate 603 is provided on one side of the threaded rod 602 at the top end of the inner side of the anaerobic treatment tank 2. The displacement plate 603 and the anaerobic treatment tank 2 form a sliding structure through the support rod 13, which can support and limit the displacement plate 603, so that the displacement plate 603 only moves in the horizontal forward and backward directions to prevent tilting.

[0047] A continuous wastewater treatment method comprises the following steps:

[0048] S1, coarsely filtering the wastewater through the solid-liquid separation structure connected to the front end of the physical separation tank 1;

[0049] S2, then the water that has been coarsely filtered in the solid-liquid separation structure is fed into the glass cylinder 8 through the liquid inlet at one end of the physical separation tank 1, and the water that has been finely filtered by the filter grid group 9 and the three-layer nylon polytetrafluoroethylene filter 14 in the glass cylinder 8 enters the physical separation tank 1;

[0050] S3, while continuously aerating the physical separation tank 1 through the aeration assembly 12 at the bottom of the physical separation tank 1 to oxygenate the water, so that the water separated in the physical separation tank 1 undergoes an initial aerobic pre-reaction;

[0051] S4, the treated water enters the anaerobic treatment tank 2 and the flocculation sedimentation tank 3 in sequence through the overflow tank 11 for corresponding treatment;

[0052] S5. The water then flows through the overflow trough 11 into the perforated glass cylinder 10 at the top of the first aerobic treatment tank 4. When the water flows through the composite filler 1 in the filler holder, it fully contacts and degrades the microbial film attached to the composite filler 1. The water then flows through the overflow trough 11 between the first aerobic treatment tank 4 and the second aerobic treatment tank 5 into the perforated glass cylinder 10 at the top of the second aerobic treatment tank 5. When the water flows through the composite filler 2 in the filler holder, it again fully contacts and degrades the microbial film attached to the composite filler 2. Both aerobic tanks are equipped with an adjustable aeration assembly 12, which allows oxygen to be added to the tanks to provide environmental conditions for aerobic microorganisms in the tanks.

[0053] S6, the final treated water is discharged from the outlet of the second aerobic treatment tank 5 in compliance with the standards;

[0054] During this process, the drive motor 601 is started at a fixed time, so that the output end of the drive motor 601 drives the threaded rod 602 to reciprocate forward and reverse. Through the threaded action of the threaded rod 602 and the displacement plate 603, the displacement plate 603 is caused to reciprocate laterally. Through the meshing action of the toothed disc 605 and the rack 606, the toothed disc 605 and the support shaft 604 are rotated together. Under the action of the pulley group 614, the symmetrically arranged guide cylinder 1 607 and the stirring rod 609, the mixing plate 610, and the guide cylinder 2 608 are rotated together through the support shaft 604, thereby facilitating large-scale rapid mixing of wastewater and anaerobic sludge through the stirring rod 609 and the mixing plate 610 that are displaced back and forth laterally and rotated. Through the sliding action of the movable frame 611 and the anaerobic treatment tank 2, the stirring rod 609 and the mixing plate 610 are caused to reciprocate longitudinally during the rotation process, thereby achieving full coverage stirring in the three-dimensional space of the tank, so as to improve the mixing efficiency and effect of the anaerobic sludge and wastewater.

[0055] At the same time, the support frame 701 and the flip plate 703 move horizontally back and forth along with the guide cylinder 2 608. The meshing action of the gear 704 and the tooth plate 705 causes the gear 704, the rotating shaft 702, and the flip plate 703 to rotate together, thereby achieving slow flipping of the settled sludge, preventing the long-term sedimentation and hardening of the sludge at the bottom from affecting the treatment effect and efficiency of domestic wastewater. In addition, the sliding action of the disc 706 and the anaerobic treatment tank 2 causes the disc 706 to drive the rotating shaft 702 and the flip plate 703 to move horizontally in the left and right directions while rotating, thereby achieving comprehensive and slow flipping of the settled sludge, so as to ensure the treatment effect of domestic wastewater.
