Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater treatment equipment, and relates to an enhanced treatment device for dyeing and printing wastewater. Background Technology

[0002] Dyeing and printing wastewater treatment is a process for purifying high-concentration, high-color, and recalcitrant wastewater generated by the textile dyeing and printing industry. It mainly uses chemical methods (such as coagulation and advanced oxidation), physical methods (such as membrane separation), and biological methods to remove pollutants, thereby promoting water reuse and achieving compliant discharge.

[0003] Early treatment primarily relied on coagulation, removing suspended solids and color by adding inorganic or composite coagulants. With increasingly stringent environmental standards, membrane separation technologies (ultrafiltration, nanofiltration, reverse osmosis) have been applied to combined processes due to their high efficiency, such as sand filtration + UF + RO / NF. Processes like MBR and MCR combine biological treatment with membrane separation, optimizing sludge treatment processes.

[0004] Existing technologies often employ a series layout, which occupies a large area and is difficult to cope with water quality fluctuations. Furthermore, each unit operates independently, and wastewater passes through each unit in a fixed order. All wastewater is treated in one unit before being discharged into the next unit. This may result in large molecular dyes (such as sulfur black) entering the biological unit directly before being fully degraded during the oxidation stage, inhibiting microbial activity. Meanwhile, small molecular organic matter (such as acetic acid) is over-mineralized during the oxidation stage, wasting oxidant. Utility Model Content

[0005] The purpose of this invention is to provide an enhanced treatment device for dyeing and printing wastewater, in order to solve the problem that in existing equipment, macromolecular dyes directly enter the biological unit when they are not completely degraded during the oxidation stage, while small molecule organic matter is over-mineralized.

[0006] To achieve the above objectives, the basic solution of this utility model is: a dyeing and printing wastewater enhanced treatment device, including a shell, a partition plate and a flow guiding mechanism;

[0007] The outer shell is divided into an oxide layer, a biological layer and a self-cleaning membrane separation layer from top to bottom. The separator is installed horizontally at the connection of each layer. The separator has nano-sized drainage holes arranged on it, and the diameter of the drainage holes increases sequentially along the arrangement direction.

[0008] The flow guiding mechanism includes automatically retractable flow guiding plates, which are respectively disposed in the oxide layer and the biological layer, and located on the side of the large drainage hole on the partition plate. The flow guiding plates are vertically arranged, and the top of the flow guiding plates is rotatably connected to the inner wall of the outer shell. A power source for controlling the swing of the flow guiding plates is connected to the connection between the flow guiding plates and the inner wall of the outer shell. The bottom of the flow guiding plates is always in contact with the upper surface of the corresponding partition plate, and the two side walls of the flow guiding plates are in contact with the opposite inner side walls of the outer shell.

[0009] The working principle and beneficial effects of this basic scheme are as follows: This technical scheme adopts a vertical layered structure, which allows wastewater to flow naturally through each unit under the action of gravity. Compared with the traditional series process, it can reduce the energy consumption of water pumps.

[0010] By using a partition plate combined with a flow guiding mechanism, the drainage holes on the partition plate have different diameters. Small-diameter drainage holes can pass through small-molecule organic matter, while large-diameter drainage holes can pass through treated macromolecular dyes.

[0011] In the initial state, the power source controls the guide plate to swing towards the side where the small-diameter drainage hole is located, so that the bottom of the guide plate can abut against the edge of the partition plate on that side. At this time, the entire partition plate is located below the guide plate.

[0012] At this point, the dyeing and printing wastewater to be treated is discharged into the oxidation layer. The wastewater undergoes an oxidation reaction in the space above the guide plate. After a short reaction time, the power source can be activated to control the guide plate to move a certain distance to the side where the large-diameter drainage hole is located. At this time, some of the small-diameter drainage holes on the partition plate are exposed on the outside of the guide plate. The small-molecule organic matter after oxidation treatment enters the biological layer through the small-diameter drainage holes on the partition plate, preventing the small-molecule organic matter from being over-oxidized.

[0013] At this point, the large-molecule dye cannot be discharged from the small-diameter drainage holes on the separator plate. The large-molecule dye remains inside the oxide layer and continues to undergo oxidation for a more thorough oxidation process. After a period of time, the guide plate is moved towards the side where the large-diameter drainage holes are located, exposing the large-diameter drainage holes to the outside of the guide plate, thus discharging the large-molecule dye from the oxide layer.

[0014] The separator and flow guiding structure separating the biological layer and the self-cleaning membrane separation layer also perform the above operations to meet the time processing requirements of different substances, discharge them in stages, control the small molecule organic matter in each layer to enter the next layer more quickly, and allow the large molecule dyes to stay for a longer time, so that the large molecule dyes are degraded more fully and the small molecule organic matter is avoided from being over-mineralized.

[0015] Furthermore, the guide plate includes a main board and an extension plate. The top of the main board is rotatably connected to the inner wall of the outer casing, and the bottom of the main board is provided with a groove with openings on both sides.

[0016] The extension plate is slidably connected to the groove, and an elastic element is provided between the inner end of the groove and the extension plate. The elastic element is always in a compressed state. The bottom of the extension plate abuts against the upper surface of the corresponding partition plate, and the width of the extension plate is equal to the width of the main plate.

[0017] The extension plate slides within the groove of the main board, enabling the extension and retraction of the guide plate. When the guide plate swings towards the side with the small-diameter drain hole, it needs to extend to ensure its bottom abuts against the partition plate. Under the action of the elastic element, the extension plate is pushed out of the groove, thus extending. Conversely, when the guide plate moves towards the side with the large-diameter drain hole, the bottom of the extension plate abuts against the partition plate. As the guide plate moves as a whole, the partition plate applies a thrust to the extension plate, pushing it into the groove and causing it to retract.

[0018] Furthermore, it also includes a pollution concentration sensor and a display module, wherein the pollution concentration sensor is respectively installed on the inner wall of the outer shell of the corresponding oxide layer, biological layer and self-cleaning membrane separation layer;

[0019] The display module is mounted on the outer wall of the housing or in the control room of the staff. The input end of the display module is connected to the output end of the pollution concentration sensor through a wireless transmission module.

[0020] The pollution concentration sensor can collect pollution data of waste in the corresponding layer and transmit it to the display module for easy viewing by staff, and also to help staff control the wastewater treatment in each layer inside the casing.

[0021] Furthermore, it also includes a limiting mechanism, which includes a groove and a slider;

[0022] The slide groove is provided on the inner wall of the outer shell on one or both sides of the partition plate, and the slide groove is arranged horizontally;

[0023] The slider is installed on the bottom side of the extension plate and is slidably connected to the groove.

[0024] A limiting mechanism is set up so that the slider on the extension plate always slides along the groove, ensuring that the bottom of the extension plate always abuts against the upper surface of the partition plate when the guide plate swings.

[0025] Furthermore, it also includes a protective layer, which is disposed on the outer wall where the guide plate contacts the inner wall of the outer casing.

[0026] A protective layer is installed to protect the contact surface between the guide plate and the inner wall of the outer shell.

[0027] Furthermore, it also includes multiple control buttons, each of which is connected to the control terminal of the corresponding power source. The control buttons are installed on the outer wall of the housing or located in the operator's control room.

[0028] A control button is provided, allowing staff to manually control the power source and thus the oscillation of the deflector. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0034] This utility model discloses an enhanced treatment device for dyeing and printing wastewater, such as Figure 1 As shown, it includes an outer shell 1, a partition plate 5, and a flow guiding mechanism. The outer shell 1 can be made of materials such as stainless steel, PP board (polypropylene), fiberglass, or concrete with anti-corrosion lining.

[0035] The outer casing 1 is divided from top to bottom into an oxidation layer 2 (chemical method), a biological layer 3, and a self-cleaning membrane separation layer 4. The oxidation layer 2, biological layer 3 (biological method), and self-cleaning membrane separation layer 4 (physical method; membrane separation technology refers to the selective separation of a mixture of molecules of different particle sizes at the molecular level when passing through a semi-permeable membrane, also known as a separation membrane or filter membrane, whose walls are covered with small pores. Based on pore size, they can be classified as microfiltration membranes (MF), ultrafiltration membranes (UF), nanofiltration membranes (NF), reverse osmosis membranes (RO), etc. Membrane separation uses cross-flow filtration or dead-end filtration methods) all utilize existing wastewater treatment units. Pipes can be installed at the bottom of the outer casing 1 to connect to other equipment or containers for discharging treated wastewater.

[0036] Ozone (1.0-1.5 g / L) and a catalyst (such as supported TiO2) are added to oxide layer 2 (e.g., by connecting a container and switch to the side wall of oxide layer 2 for addition). 20-50 μm bubbles are generated through a microporous aeration disc, with a contact time ≥30 min (a timer can be set). A UV-LED array (wavelength 254 nm + 365 nm) can also be installed (e.g., by bonding, welding) on ​​the inner wall of oxide layer 2, with a light intensity ≥80 mW / cm². This is similar to the ozone oxidation operation described in patent CN101638286B.

[0037] The biological layer 3 can be inoculated with highly efficient decolorizing bacteria (such as white-rot fungi + denitrifying bacteria), and the self-cleaning membrane separation layer 4 can be equipped with a hollow fiber ultrafiltration membrane and a piezoelectric ceramic to drive the membrane fibers to vibrate. As mentioned in patent CN101633541B, this involves operations such as biological filtration, ozone oxidation, air flotation, and membrane separation. Each layer can be connected to external treatment equipment, and a sealing valve can be provided on the side wall of the outer shell 1. The interior can be cleaned through this valve when cleaning is required. Windows can also be opened on the side wall to allow the addition of oxidants and other materials.

[0038] The partition plate 5 is installed horizontally (it can be glued, welded, riveted, snap-fitted, etc.) at the joints of each layer. The partition plate 5 has nano-sized drainage holes 7 arranged on it, and the diameter of the drainage holes 7 increases sequentially along the arrangement direction. Figure 1 The diameters of the drain holes 7 in the middle increase sequentially from right to left. Figure 1 The larger diameter of the drainage hole 7 is an enlargement operation performed to facilitate the display of the structure.

[0039] The separator 5 can be made of anodized aluminum oxide (AAO template), porous silicon carbide (SiC) ceramic, nano-titanium (Ti) metal film (electron beam lithography + electrochemical etching), graphene composite film, etc. Existing filter membrane structures can be used, with matching drainage holes set during manufacturing. Alternatively, filter membranes with different pore sizes can be used, and multiple filter membranes can be sequentially spliced ​​together (e.g., laser micro-welding, nano-silver brazing, 3D printed transition layer connection, biomimetic interlocking structure splicing, polymer thermal fusion composite, modular clamp sealing, etc.) to form a single separator 5.

[0040] The flow guiding mechanism includes an automatically retractable flow guiding plate 6, which is respectively installed in the oxide layer 2 and the biological layer 3, and located on the side of the large drainage hole 7 on the partition plate 5. The flow guiding plate 6 is vertically arranged, and its top is rotatably connected to the inner wall of the outer shell 1. A power source (such as a bidirectional motor) is connected to the connection between the flow guiding plate 6 and the inner wall of the outer shell 1 to control the swing of the flow guiding plate 6. For example, a horizontal rotating shaft 8 is fixedly connected to the top of the flow guiding plate 6, and an installation groove is provided on the inner wall of the outer shell 1. The power source is fixedly installed (e.g., by welding, bonding, riveting, etc.) in the installation groove, and the rotating shaft 8 is connected to the output shaft of the power source (e.g., by welding, bonding, pin connection, etc.). When the power source is started, it can drive the rotating shaft 8 to rotate, thereby realizing the swing of the flow guiding plate 6.

[0041] The bottom of the flow guide plate 6 always abuts against the upper surface of the corresponding partition plate 5, and the two side walls of the flow guide plate 6 are in contact with the inner side walls of the outer shell 1. In this way, the side walls, bottom and contact surfaces of the flow guide plate 6 form a sealed structure, which can divide the corresponding oxide layer 2 or biological layer 3 into left and right spaces, and achieve flow guidance by the tilt angle of the flow guide plate 6.

[0042] This invention adopts a vertical layered structure, which allows wastewater to flow naturally through each unit under the action of gravity. Compared with the traditional series process, it can reduce the energy consumption of water pumps.

[0043] By using the partition plate 5 in combination with the flow guiding mechanism, the drainage holes 7 on the partition plate 5 have different diameters. The small-diameter drainage holes 7 can pass through small molecule organic matter, while the large-diameter drainage holes 7 can pass through the treated macromolecular dyes.

[0044] In the initial state, the guide plate 6 is swung towards the side where the small-diameter drainage hole 7 is located by using the power source, so that the bottom of the guide plate 6 can abut against the edge of the partition plate 5 on that side. At this time, the partition plate 5 is located entirely below the guide plate 6.

[0045] At this time, the dyeing and printing wastewater to be treated is discharged into the oxidation layer 2 (such as a structure that connects to a drainage pipe at the top of the outer shell 1). The wastewater undergoes an oxidation reaction in the space above the guide plate 6. After a short reaction time, the power source can be started to control the guide plate 6 to move a certain distance to the side where the large-diameter drainage hole 7 is located. At this time, some of the small-diameter drainage holes 7 on the partition plate 5 are exposed on the outside of the guide plate 6. The small-molecule organic matter after oxidation treatment enters the biological layer 3 through the small-diameter drainage holes 7 on the partition plate 5 to prevent the small-molecule organic matter from being over-oxidized.

[0046] At this point, the macromolecular dye cannot be discharged from the small-diameter drainage hole 7 on the separator plate 5. The macromolecular dye remains in the oxide layer 2 and continues to undergo oxidation treatment for a more thorough oxidation process. After a period of time, the guide plate 6 is moved towards the side where the large-diameter drainage hole 7 is located, exposing the large-diameter drainage hole 7 to the outside of the guide plate 6, thus discharging the macromolecular dye from the oxide layer 2.

[0047] The separator 5 and the flow guiding structure that separate the biological layer 3 from the self-cleaning membrane separation layer 4 also perform the above operations to meet the time processing requirements of different substances, discharge them in stages, control the small molecule organic matter in each layer to enter the next layer faster, and allow the large molecule dyes to stay for a longer time, so that the large molecule dyes are degraded more fully and the small molecule organic matter is avoided from being over-mineralized.

[0048] Multiple timers can be set as needed, and the existing structure of the timers can be used to control the power source, thereby controlling the swing angle of the guide plate 6 each time, so as to discharge small molecules, medium molecules, and large molecules in different time periods.

[0049] Alternatively, the dyeing and printing wastewater intensified treatment device may also include multiple control buttons 16. Each control button 16 is electrically connected to the control terminal of its corresponding power source. The control buttons 16 are installed (e.g., glued, welded, riveted, etc.) on the outer wall of the housing 1 or located in the operator's control room. The control buttons 16 can be categorized into primary swing control buttons 16, secondary swing control buttons 16, or more secondary swing control buttons 16, each electrically connected to a primary swing control terminal of the power source, a secondary swing control terminal, and so on. Different control terminals of the power source correspond to the swing angle of the guide plate 6 as it moves towards the side containing the large-diameter drainage hole 7. Operators can press different control buttons 16 according to a preset time to control the swing of the guide plate 6.

[0050] In a preferred embodiment of this utility model, the guide plate 6 includes a main board 9 and an extension plate 10. The top of the main board 9 is rotatably connected to the inner wall of the outer shell 1, and the bottom of the main board 9 is provided with a groove 11 with openings on both sides.

[0051] The extension plate 10 is slidably connected to the groove 11. An elastic element 12 is provided between the inner end of the groove 11 and the extension plate 10. The elastic element 12 can be a device such as a returnable spring with good elasticity. One end of the elastic element 12 is connected to the inner end of the groove 11 (e.g., by welding, bonding, snap-fitting, etc.), and the other end is connected to the end of the extension plate 10 (e.g., by welding, bonding, snap-fitting, etc.). The elastic element 12 is always in a compressed state. The bottom of the extension plate 10 abuts against the upper surface of the corresponding partition plate 5. The width of the extension plate 10 is equal to the width of the main plate 9.

[0052] The extension plate 10 slides within the groove 11 of the main plate 9, enabling the extension and retraction of the guide plate 6. When the guide plate 6 swings towards the side where the small-diameter drain hole 7 is located, the guide plate 6 needs to extend to ensure that its bottom abuts against the partition plate 5. Under the action of the elastic element 12, the extension plate 10 is pushed outward from the groove 11, thus extending. When the guide plate 6 moves towards the side where the large-diameter drain hole 7 is located, the bottom of the extension plate 10 abuts against the partition plate 5. As the guide plate 6 moves as a whole, the partition plate 5 can apply a pushing force to the extension plate 10, pushing the extension plate 10 into the groove 11, causing the extension plate 10 to retract into the groove 11.

[0053] In a preferred embodiment of this utility model, the dyeing and printing wastewater enhanced treatment device further includes a pollutant concentration sensor 13 (such as an oxidation layer 2 monitoring sensor: COD online analyzer: HACH CODmax II, WTW VARIO COD, etc.; ozone concentration sensor: ATIQ45H, ProMinent ORP-290, etc.; biolayer 3 monitoring sensor: BOD5 rapid analyzer: LOVIBONDBOD Trak II, etc.; ammonia nitrogen / nitrate nitrogen sensor: YSI EXO2NH4, HACH Amtax sc, etc.; membrane separation layer monitoring sensor: turbidity / suspended solids sensor: HACH Sol itaxsc, E+H Turbimax CUS51 D, etc.; a multi-parameter spectrometer probe and an electrochemical multi-parameter instrument (METTLER TOLEDO InPro8000) can also be set) and a display module 14.

[0054] Pollution concentration sensors 13 are installed (e.g., by bonding, welding, embedding, etc.) on the inner wall of the outer shell 1 of the corresponding oxide layer 2, biological layer 3 and self-cleaning membrane separation layer 4. For example, the oxide layer 2 sensor can be installed in the vertical pipe section of the inlet 0.3-0.5m away from the liquid surface of the oxide layer 2. The installation position can be adjusted as needed.

[0055] The display module 14 can be an existing smart display screen, monitor, etc. The display module 14 is set (e.g., glued, welded, riveted, etc.) on the outer wall of the housing 1 or in the control room of the staff. The input end of the display module 14 is electrically connected to the output end of the pollution concentration sensor 13 through a wireless transmission module (e.g., 5G network, WIFI, Bluetooth, etc.).

[0056] The pollution concentration sensor 13 can collect pollution data of waste in the corresponding layer and transmit it to the display module 14 for easy viewing by staff and to facilitate staff control of wastewater treatment in each layer inside the housing 1.

[0057] In a preferred embodiment of this utility model, the dyeing and printing wastewater enhanced treatment device further includes a limiting mechanism, which comprises a chute 15 and a slider. The chute 15 is disposed on the inner wall of the outer shell 1 corresponding to one or both sides of the partition plate 5, and the chute 15 is arranged laterally. The slider is installed (e.g., by bonding, welding, etc.) on the bottom side of the extension plate 10, and the slider is slidably connected to the chute 15.

[0058] A limiting mechanism is set up so that the slider on the extension plate 10 always slides along the slide groove 15, ensuring that the bottom of the extension plate 10 always abuts against the upper surface of the partition plate 5 when the guide plate 6 swings.

[0059] In a preferred embodiment of this utility model, the dyeing and printing wastewater enhanced treatment device further includes a protective layer, which is disposed on the outer wall of the guide plate 6 in contact with the inner wall of the outer shell 1. The guide plate 6 can be made of stainless steel or other materials, and the protective layer can be made of a PTFE bottom layer (0.2-0.5mm) and a graphene top layer to protect the contact surface between the guide plate 6 and the inner wall of the outer shell 1 and also increase the sealing of the contact area.
