Description

Technical Field

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

[0002] Wastewater refers to water bodies that have lost their original functions during human activities, containing pollutants (such as chemical substances, organic matters, heavy metals, etc.), which need to be treated before being safely discharged or reused. Its sources cover fields such as life, industry, and agriculture. According to the degree of pollution, it can be divided into "black water" (high pollution) and "grey water" (low pollution). Wastewater mainly includes industrial wastewater, domestic wastewater, and construction wastewater. Since there are many pollutants in the wastewater, it cannot be directly discharged and requires the use of wastewater pretreatment equipment for treatment. However, the structure of this pretreatment equipment is usually too simple. Although it can play a certain role in filtering and clarification, this pretreatment equipment will still continuously generate suspended solids or precipitates during subsequent reactions and treatments, resulting in the presence of floating substances, precipitates, and suspended solids in the effluent, affecting normal wastewater discharge and subsequent possible further purification operations, causing low work and operation efficiency, and being prone to uneven and incomplete treatment.

[0003] According to a continuous treatment system for domestic sewage with the publication number CN211284087U, it includes a treatment tank body, which is divided into several sub-tank bodies. Adjacent sub-tank bodies are connected through overflow holes. The sub-tank bodies at least include a physical separation tank, an anaerobic treatment tank, and an aerobic treatment tank arranged in sequence. There are fiberglass cylinders in the physical separation tank and the aerobic treatment tank. The upper part of the fiberglass cylinder is open and faces the overflow hole of the upper-level tank body. At the same time, an open side surface closed by a multi-layer nylon polytetrafluoroethylene filter screen is also arranged on the side of the fiberglass cylinder. A filter grille assembly is arranged in the fiberglass cylinder of the physical separation tank, and a filler support is arranged in the fiberglass cylinder of the aerobic treatment tank. During the physical / chemical / biological treatment of sewage, sediment residues and suspended solids are filtered multiple times. The treated sewage can be directly discharged, or can be used for irrigation or sent to a domestic sewage treatment plant for further purification treatment, and can effectively reduce the operation burden of relevant equipment when entering the water recovery pipeline of the domestic sewage treatment plant to improve its operation stability, reliability, and service life.

[0004] Regarding the above - mentioned related solutions, a submersible mixer is used to mix anaerobic sludge and wastewater, so that the microorganisms in the anaerobic sludge can contact and degrade pollutants. However, the submersible mixer can only form a circulating flow on the horizontal plane, resulting in a decrease in the mixing efficiency in the vertical direction, insufficient contact area between the sludge and the water body, the existence of a stirring dead - zone space, and the need to configure multiple independent motors to drive the fixed - type submersible mixer, increasing the energy - consumption cost. In addition, sludge is likely to precipitate at the bottom of the anaerobic treatment tank. The long - term precipitated sludge will occupy the effective volume of the anaerobic treatment tank, reduce the contact area between the wastewater and the microorganisms, resulting in a decrease in the organic matter degradation rate, and it is difficult to separate the sludge after it becomes muddy and caked, further hindering the decomposition of pollutants, easily deteriorating the water quality. At the same time, the long - term precipitation of sludge easily leads to uneven flow patterns in the anaerobic treatment tank, forming dead zones or short - circuits, reducing the utilization rate of the hydraulic retention time.

The first guide rod is used to make the movable frame perform longitudinal reciprocating motion.

[0010] Preferably, a support rod passing through the displacement plate is arranged on one side of the threaded rod at the top end inside the anaerobic treatment tank. The displacement plate and the anaerobic treatment tank form a sliding structure through the support rod.

[0012] Preferably, discs are arranged on both sides of the rotating shaft. A limit member II which forms a sliding structure with the second guide rod is arranged on the side of the disc away from the gear, and the second guide rod is used to make the turning plate perform lateral left - right movement during the process of moving back and forth and rotating horizontally.

[0014] Preferably, a filter grille group and three nylon polytetrafluoroethylene filter meshes are sequentially arranged in the glass cylinder body from back to front.

[0015] A continuous wastewater treatment method includes the following treatment steps: S1. Coarsely filter the wastewater through the solid - liquid separation structure connected to the front end of the physical separation tank; S2. Then send the water body coarsely filtered in the solid - liquid separation structure into the glass cylinder body through the liquid inlet at one end of the physical separation tank, and the water body finely filtered by the filter grille group and the three - layer nylon polytetrafluoroethylene filter meshes in the glass cylinder body enters the physical separation tank; S3.

The treated water enters the anaerobic treatment tank and the flocculation sedimentation tank in sequence through the overflow trough for corresponding treatment. The displacement mechanism is used to fully stir and mix the anaerobic sludge and water, and the anti-caking plate mechanism is used to turn the precipitated sludge to prevent caking. S5. Subsequently, it enters the perforated glass cylinder at the top of the first aerobic treatment tank through the overflow trough. When the water flows through the combined packing one in the packing support, it fully contacts and degrades with the microbial film attached to the combined packing one, and enters the perforated glass cylinder at the top of the second aerobic treatment tank through the overflow trough between the first aerobic treatment tank and the second aerobic treatment tank. When the water flows through the combined packing two in the packing support, it fully contacts and degrades with the microbial film attached to the combined packing two again. Adjustable aeration assemblies are provided in both two-stage aerobic tanks. S6. The finally treated water is discharged up to standard from the water outlet of the second aerobic treatment tank.

[0016] 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. The threaded rod drives the displacement plate to move horizontally back and forth, and the three-dimensional composite movement of the stirring rod is realized by the transmission of the gear disc-rack-guide rod one, that is, horizontal displacement + rotation + vertical 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-rack-guide rod two realizes the rotation and horizontal movement of the turning plate, and the symmetrically spaced turning plates slowly turn the bottom sludge in a low-resistance mode, effectively preventing caking and increasing the microbial activity retention rate; the continuous wastewater treatment equipment has a simple and efficient structure, a single motor drive replaces multiple power sources, the system complexity and energy consumption are significantly reduced, and the mechanical linkage replaces the electronic collaborative control, which can eliminate the risk of multi-motor timing error, enhance the operation reliability, extend the service life and reduce the maintenance cost at the same time.

[0017] 1. In the continuous wastewater treatment equipment, when the driving motor works, the output end of the driving motor drives the threaded rod to rotate forward and backward reciprocally, so that the displacement plate makes a horizontal reciprocating movement. At the same time, the gear disc and the support shaft rotate together, and under the action of the pulley group, the symmetrically arranged guide cylinder one, the stirring rod and the mixing plate rotate together through the support shaft, so as to facilitate the large-area and rapid mixing of the wastewater and the anaerobic sludge through the horizontally displaced and rotating stirring rod and mixing plate. During the rotation of the stirring rod and the mixing plate, they make a longitudinal reciprocating movement through the cooperation of the guide member one and the guide rod one, so as to realize the full-coverage stirring in the three-dimensional space of the tank. By dynamically adjusting the stirring path, the dead zone problem caused by traditional fixed stirring is reduced, the mixing efficiency and effect of the anaerobic sludge and the wastewater are improved, the effective contact area is greatly increased, so as to ensure the efficient contact and degradation of microorganisms and pollutants. In addition, compared with the traditional multi-motor system, the energy consumption is reduced, the equipment operation noise is reduced, and the modular design shortens the replacement time of key components and reduces the annual maintenance cost.

[0018] 2. When the continuous wastewater treatment equipment makes the support frame and the turning plate move horizontally back and forth together with the guide cylinder II, the gear, the rotating shaft and the turning plate rotate together, so as to realize the slow turning of the precipitated sludge, prevent the long-term precipitation and caking of the bottom sludge from affecting the treatment effect and efficiency of domestic wastewater. The disc drives the rotating shaft and the turning plate to make a horizontal movement in the left-right direction while rotating through the cooperation of the limiting member II and the guide rod II, so as to realize the comprehensive and slow turning of the precipitated sludge, improve the turning efficiency and effect, ensure the treatment effect of domestic wastewater, and the multiple symmetrically arranged turning plates are arranged at intervals, so that the resistance during turning can be reduced, energy consumption can be saved, and both the movement and turning are relatively labor-saving. In addition, the horizontal back-and-forth and left-right displacements and rotations of the turning plate can also serve the purpose of quickly mixing the wastewater and the anaerobic sludge.

[0019] 3. The present invention drives the displacement plate and the support frame to move horizontally back and forth together by a single driving motor, and through the horizontal back-and-forth movement of the displacement plate and the support frame, the tooth disc and the stirring rod, the gear and the rotating shaft perform reciprocating forward and reverse rotations, the stirring rod makes a longitudinal reciprocating movement, and the turning plate makes a horizontal left-right movement, so that the comprehensive mixing of the anaerobic sludge and the wastewater and the comprehensive and slow turning of the precipitated sludge can be realized, thereby improving the mixing uniformity, avoiding the caking of the precipitated sludge through slow turning, maintaining the microbial activity, and having a simple and efficient structure, significantly reducing the system complexity and energy consumption. And through mechanical linkage to replace electronic collaborative control, the risk of multi-motor timing error can be eliminated, the operation reliability is enhanced, the service life is extended, and the maintenance cost is reduced.

At the top of one side of the second aerobic treatment tank 5, there is a water outlet. The aerobic tanks 4 / 5 use microporous aerators, and are equipped with a photovoltaic energy storage system to reduce the external power consumption by 30%; Refer to Figure 1 and Figure 2 It 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 roughly filtered in the solid-liquid separation structure is sent 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 grille group 9 and the three-layer nylon polytetrafluoroethylene filter screen 14 in the glass cylinder 8 enters the physical separation tank 1. At the same time, the physical separation tank 1 is continuously aerated through the aeration assembly 12 at the bottom of the physical separation tank 1 to oxygenate the water body, so as to carry out an initial aerobic pre-reaction on the separated water body in the physical separation tank 1. The treated water body enters the anaerobic treatment tank 2 and the flocculation sedimentation tank 3 in sequence through the overflow tank 11, and then enters the two-stage aerobic treatment unit in an up-flow manner. The perforated glass cylinders 10 at the tops of the first aerobic treatment tank 4 and the second aerobic treatment tank 5. When the water body flows through the combined packing one / two in the packing support, it fully contacts and degrades with the microbial film attached to the combined packing one / two. Both two-stage aerobic tanks are equipped with adjustable aeration assemblies 12. The final treated water is discharged up to standard from the water outlet of the second aerobic treatment tank 5, thus completing the continuous treatment of wastewater.

[0024] Refer to Figures 1-8It can be seen that a displacement mechanism 6 is arranged through the inside 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. A stirring rod 609 is connected to the inside of the movable frame 611 through a bearing. Mixing plates 610 are arranged at equal angles on the outer side of the stirring rod 609. Guide cylinders one 607 and guide cylinders two 608 are respectively slidably connected to both ends of the stirring rod 609. One side of the top end of the displacement plate 603 is rotatably connected to a support shaft 604 through a bearing. A gear disk 605 engaged with the rack 606 is sleeved on the outer surface of the support shaft 604, and the gear disk 605 is used to drive the support shaft 604 to rotate. Pulley groups 614 are connected between the support shaft 604 and the guide cylinder one 607 and between two guide cylinders one 607, and the pulley groups 614 are used to make the guide cylinder one 607 rotate synchronously with the support shaft 604. The guide cylinder one 607 is rotatably connected to the displacement plate 603 through a bearing. Guide rods one 613 are arranged on both sides of the inside of the anaerobic treatment tank 2 where the movable frame 611 is located. Limit members one 612 are arranged on both sides of the movable frame 611. The limit members one 612 and the anaerobic treatment tank 2 form a sliding structure through the guide rods one 613, and the guide rods one 613 are arranged in a wavy structure. The guide rods one 613 are 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 coupling, and the threaded rod 602 is threadedly connected to the displacement plate 603; Refer to Figures 1-8It can be known that when the drive motor 601 works, the output end of the drive motor 601 drives the threaded rod 602 to perform reciprocating forward and reverse rotation. Since the threaded rod 602 is threadedly connected to the displacement plate 603, the displacement plate 603 makes a transverse reciprocating movement. Since the gear disk 605 is meshed and connected to the rack 606, the gear disk 605 and the support shaft 604 rotate together, and under the action of the pulley group 614, the symmetrically arranged guide cylinder one 607, the stirring rod 609, and the mixing plate 610 rotate together through the support shaft 604, so as to facilitate the large-area and rapid mixing of the wastewater and the anaerobic sludge through the transversely displaced and rotating stirring rod 609 and mixing plate 610. Since the movable frame 611 is slidably connected to the anaerobic treatment tank 2 through the guide member one and the guide rod one 613, and the stirring rod 609 is slidably connected to both the guide cylinder one 607 and the guide cylinder two 608, the stirring rod 609 and the mixing plate 610 make longitudinal reciprocating movements during the rotation process, so as to realize the full-coverage stirring in the three-dimensional space of the tank. By dynamically adjusting the stirring path, the dead zone problem caused by traditional fixed stirring is reduced, the mixing efficiency and effect of the anaerobic sludge and the wastewater are improved, and the effective contact area is greatly increased, so as to ensure the efficient contact and degradation of microorganisms and pollutants. Moreover, compared with the traditional multi-motor system, the energy consumption is reduced, and the operating noise of the equipment is reduced. In addition, the modular design shortens the replacement time of key components and reduces the annual maintenance cost.

[0025] Refer to Figure 1 、 Figure 2 and Figures 7-9 It can be known that a anti-caking plate mechanism 7 is arranged at the bottom end of the guide cylinder two 608 on the inner side of the anaerobic treatment tank 2. The anti-caking plate mechanism 7 includes a support frame 701 connected to the guide cylinder two 608 through a bearing, a toothed plate member 705 welded to the anaerobic treatment tank 2, and a guide rod two 708. A rotating shaft 702 is movably connected to the inner side of the support frame 701. Turning plates 703 are symmetrically arranged on the surface of the rotating shaft 702. Gears 704 meshed with the toothed plate member 705 are arranged on both sides of the support frame 701 on the surface of the rotating shaft 702. The toothed plate member 705 is composed of a toothed plate and side retaining strips. The side retaining strips can limit the gears 704 so that they are always in a meshed state with the toothed plate member 705. Discs 706 are arranged on both sides of the rotating shaft 702. A limiting member two 707 which forms a sliding structure with the guide rod two 708 is arranged on the side of the disc 706 away from the gear 704. The guide rod two 708 is used to make the turning plate 703 move left and right horizontally during the process of moving back and forth and rotating horizontally. Guide grooves 709 are symmetrically opened on the surface of the rotating shaft 702. Guide blocks 710 which form a sliding structure with the guide grooves 709 are symmetrically arranged on the inner surface of the gear 704. Through the cooperation of the guide grooves 709 and the guide blocks 710, the position and operating state of the gear 704 will not be affected when the rotating shaft 702 moves left and right horizontally; Refer to Figure 1 、Figure 2 and Figures 7-9 It can be seen that since the second guiding cylinder 608 and the support frame 701 which are symmetrically arranged are connected by bearings, the support frame 701 and the turning plate 703 move horizontally back and forth together with the second guiding cylinder 608. Since the gear 704 and the toothed plate member 705 are meshed and connected, the gear 704, the rotating shaft 702 and the turning plate 703 rotate together, so as to realize the slow turning of the precipitated sludge, prevent the long-term precipitation and caking of the bottom sludge from affecting the treatment effect and efficiency of domestic wastewater. Since the disc 706 and the anaerobic treatment tank 2, and the gear 704 and the rotating shaft 702 are respectively connected by sliding through the second limiting member 707, the second guiding rod 708, the guiding block 710 and the guiding groove 709, and the rotating shaft 702 and the disc 706 are connected by bearings, the disc 706 drives the rotating shaft 702 and the turning plate 703 to move horizontally in the left and right directions while rotating, so as to realize the comprehensive and slow turning of the precipitated sludge, so as to improve the turning efficiency and effect, and thus ensure the treatment effect of domestic wastewater. Moreover, the multiple turning plates 703 which are symmetrically arranged are arranged at intervals, so that the resistance during turning can be reduced, the energy consumption can be saved, and the movement and turning are relatively labor-saving. In addition, the horizontal back-and-forth and left-and-right displacements and rotations of the turning plate 703 can also serve the purpose of quickly mixing the wastewater and the anaerobic sludge.

[0026] Refer to Figures 1-3 It can be seen that a support rod 13 penetrating the displacement plate 603 is arranged on one side of the threaded rod 602 at the top end inside 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 play a role in supporting and limiting the displacement plate 603, so that the displacement plate 603 only moves horizontally in the front and back directions and prevents tilting.

[0027] A continuous wastewater treatment method includes the following treatment steps: S1. Coarsely filter the wastewater through the solid-liquid separation structure connected to the front end of the physical separation tank 1; S2. Then, send the water body coarsely filtered in the solid-liquid separation structure into the glass cylinder 8 through the liquid inlet at one end of the physical separation tank 1, and let the water body finely filtered by the filter grid group 9 and the three-layer nylon polytetrafluoroethylene filter screen 14 in the glass cylinder 8 enter the physical separation tank 1; S3. At the same time, continuously aerate the physical separation tank 1 through the aeration assembly 12 at the bottom of the physical separation tank 1 to oxygenate the water body, so that the water body separated in the physical separation tank 1 undergoes an initial aerobic pre-reaction; S4. The treated water body enters the anaerobic treatment tank 2 and the flocculation sedimentation tank 3 in sequence through the overflow tank 11 for corresponding treatment; S5. Subsequently, it enters the perforated glass cylinder 10 at the top of the first aerobic treatment tank 4 through the overflow tank 11. When the water body flows through the combined packing one in the packing support, it fully contacts and degrades with the microbial film attached to the combined packing one, and then enters the perforated glass cylinder 10 at the top of the second aerobic treatment tank 5 through the overflow tank 11 between the first aerobic treatment tank 4 and the second aerobic treatment tank 5. When the water body flows through the combined packing two in the packing support, it fully contacts and degrades with the microbial film attached to the combined packing two again. Adjustable aeration assemblies 12 are provided in both aerobic tanks, enabling oxygen to be filled into the tanks to provide environmental conditions for aerobic microorganisms in the tanks. S6. The finally treated water is discharged up to standard from the water outlet of the second aerobic treatment tank 5. During this process, the driving motor 601 is started regularly, so that the output end of the driving motor 601 drives the threaded rod 602 to perform reciprocating forward and reverse rotations. Through the threaded action of the threaded rod 602 and the displacement plate 603, the displacement plate 603 makes a transverse reciprocating movement. Through the meshing action of the gear disk 605 and the rack 606, the gear disk 605 and the support shaft 604 rotate together, and under the action of the pulley group 614, the symmetrically arranged guide cylinder one 607, the stirring rod 609, the mixing plate 610, and the guide cylinder two 608 rotate together through the support shaft 604, thus facilitating the large-area and rapid mixing of the wastewater and the anaerobic sludge through the horizontally moving back and forth and rotating stirring rod 609 and mixing plate 610. Through the sliding action of the movable frame 611 and the anaerobic treatment tank 2, the stirring rod 609 and the mixing plate 610 make a longitudinal reciprocating movement during rotation, thus realizing the 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 the wastewater. Meanwhile, the support frame 701 and the turning plate 703 move horizontally back and forth following the guide cylinder two 608. Through the meshing action of the gear 704 and the toothed plate part 705, the gear 704, the rotating shaft 702, and the turning plate 703 rotate together, thus realizing the slow turning of the precipitated sludge to prevent the long-term sedimentation and caking of the bottom sludge from affecting the treatment effect and efficiency of domestic wastewater. And through the sliding action of the disk 706 and the anaerobic treatment tank 2, the disk 706 drives the rotating shaft 702 and the turning plate 703 to make a lateral movement in the left and right directions while rotating, thus realizing the full and slow turning of the precipitated sludge to ensure the treatment effect of domestic wastewater. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
