Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and more specifically, to a novel pollutant membrane separation water treatment device. Background Technology

[0002] The field of wastewater treatment technology, especially for treating water bodies containing new pollutants, has always faced numerous challenges. With industrial development and the widespread use of new chemicals, new pollutants such as antibiotics and endocrine disruptors are constantly emerging, and these pollutants are difficult to remove effectively using traditional wastewater treatment processes. Existing integrated wastewater treatment devices mostly employ biochemical treatment processes, such as the AAO process and its variations, which are not only energy-intensive but also have limited removal efficiency for new pollutants. In membrane separation water treatment technology, although membrane modules can retain new pollutants to some extent, if the raw water is not adequately pretreated, large particulate impurities, suspended solids, and organic matter will quickly clog the membrane pores, increasing the risk of membrane fouling, leading to a decrease in membrane flux. Frequent cleaning operations not only increase operating costs but also shorten the lifespan of the membrane modules, greatly limiting the application of membrane separation technology in the treatment of new pollutants. At the same time, traditional pretreatment methods, such as simple filtration and sedimentation, cannot specifically remove new pollutants and cannot meet the stringent requirements of membrane separation for influent water quality. How to invent a membrane separation water treatment device for new pollutants to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a new pollutant membrane separation water treatment device, which aims to improve the existing sewage treatment technology for treating water containing new pollutants, which has problems such as high energy consumption, limited removal effect of new pollutants, and easy fouling and short service life of membrane components in membrane separation technology.

[0004] This invention is implemented as follows: A novel pollutant membrane separation water treatment device includes a shell. Two vertically distributed partitions are integrally arranged between the inner walls of the shell, dividing the internal space of the shell into three chambers distributed from top to bottom.

The outer filter cartridge, the middle filter cartridge, and the inner filter cartridge are coaxially arranged. The bottom surface of the outer filter cartridge is rotatably connected to the upper surface of the transparent viewing window above and is simultaneously fixedly connected to the output shaft of the drive device. The outer filter cartridge, the middle filter cartridge, and the inner filter cartridge are integrally formed, and two packing gaps are formed between them. The two packing gaps are respectively filled with different adsorption materials.

[0007] In a preferred embodiment of this utility model, the diameters of the filter holes on the outer wall of the outer filter cylinder, the middle filter cylinder, and the inner filter cylinder are arranged from small to large.

[0008] In a preferred embodiment of this utility model, the top of the outer filter cartridge is detachably connected to a cartridge cover, the cartridge cover has a connecting hole in the middle, and the bottom end of the water inlet channel passes through the connecting hole, passes through the cartridge cover, and extends into the inner filter cartridge.

[0009] In a preferred embodiment of this utility model, the upper surface of the cylinder cover is provided with a plurality of evenly distributed insertion holes, each insertion hole being fitted with a fastener, one end of each fastener being threadedly connected to a corresponding threaded connection hole, and the plurality of threaded connection holes being provided on the upper end face of the outer filter cylinder.

[0010] In a preferred embodiment of this utility model, the driving device is a motor, which is fixedly installed in a sealed mounting box. The sealed mounting box is located on the bottom surface of the upper partition. One end of the motor output shaft extends through an extension hole on the surface of the partition to the other side of the partition and is fixedly connected to the bottom surface of the outer filter cartridge.

[0011] In a preferred embodiment of this utility model, the oxidation treatment unit includes a plurality of ozone aeration heads, each of which is detachably installed in a corresponding sealing mounting hole. The plurality of sealing mounting holes are formed on the inner wall of the bottommost strong part. One end of each ozone aeration head extends to the outside of the outer shell through the corresponding sealing mounting hole and communicates with the upper surface of the gas collection box. One end of a connecting pipe is connected to the bottom surface of the gas collection box, and the other end of the connecting pipe is connected to the output end of the ozone generator.

[0014] The beneficial effects of this invention are as follows: This invention provides a novel pollutant membrane separation water treatment device. During use, by setting up a pretreatment adsorption unit and utilizing multi-stage filter cartridges and different adsorption materials, large particulate impurities in wastewater are initially filtered and adsorbed. This effectively reduces the impurity content entering the membrane module separation unit, alleviates the pressure on membrane separation, extends the service life of the membrane module, and lowers operating costs. Simultaneously, the synergistic effect of the membrane module separation unit and the oxidation treatment unit can efficiently remove new pollutants from wastewater, improving effluent quality. The device has a compact overall structure and is easy to operate. It has significant application advantages in wastewater treatment, especially in the treatment of aquaculture effluent and industrial wastewater containing new pollutants, achieving the goal of low-energy consumption and high-efficiency wastewater treatment.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a new pollutant membrane separation water treatment device, including a shell 1, with two vertically distributed partitions 101 integrally arranged between the inner walls of the shell 1. The two partitions 101 divide the internal space of the shell 1 into three chambers distributed from top to bottom. The uppermost chamber is provided with a pretreatment adsorption unit 2, the middle chamber is fixedly installed with a membrane module separation unit 3, and the lowermost chamber is provided with an oxidation treatment unit 4. The top surface of the shell 1 has an installation hole, through which a water inlet channel 103 is detachably connected. The bottom side surface of the shell 1 has a drainage channel 104, which communicates with the lowermost chamber. The pretreatment adsorption unit 2 includes multi-stage filter cartridges, with the bottom ends of the multi-stage filter cartridges rotatably mounted on the upper surface of the upper partition 101, and the bottom end of the water inlet channel 103 extends into the innermost filter cartridge. There are packing gaps between each stage of filter cartridges, and each packing gap is filled with adsorbent material. The surface of the upper partition 101 has several connecting ports 105 connecting the upper and middle chambers.

[0023] It should be noted that a sealing cover plate that can be detachably connected to the main body can be provided on the top of the outer shell 1. The sealing cover plate is connected to the main body of the outer shell 1 by fasteners. The two partitions 101 are also designed to be detachably connected to the inner wall of the main body of the outer shell 1. In the later maintenance and cleaning work, the sealing cover plate can be opened and the two partitions 101 can be removed in turn to complete the overall disassembly, which improves the convenience of later maintenance and cleaning work.

[0024] Please see Figure 1 A transparent viewing window 102 is provided on one side surface of the outer casing 1, and a maintenance window is provided on the other side surface of the outer casing 1. A sealing door is rotatably connected to one edge of the maintenance window, and a locking mechanism that can cooperate with the sealing door and the outer casing 1 is provided.

[0025] A transparent viewing window 102 is embedded in one side surface of the housing 1. It can be made of a high-strength, corrosion-resistant transparent material, such as plexiglass or tempered glass, ensuring clear observation of the internal components without opening the device. A maintenance window is located on the other side surface of the housing 1, its size determined by the dimensions of the internal components and maintenance requirements. A sealed door is hinged to one edge of the maintenance window. The locking mechanism between the sealed door and the housing 1 can use common locks, such as door locks or latches, ensuring a tight seal when the door is closed and preventing sewage leakage and the entry of external impurities. The transparent viewing window 102 and the maintenance window improve the maintainability and visibility of the device. Operators can promptly detect abnormalities inside the device through the viewing window, such as filter cartridge blockage or membrane module fouling. The maintenance window facilitates operator access to the device for component replacement, cleaning, and other maintenance work, reducing downtime due to malfunctions and improving the operational stability of the device.

[0026] Please see Figures 2 to 4 The multi-stage filter cartridge includes an outer filter cartridge 201, a middle filter cartridge 202, and an inner filter cartridge 203. The outer filter cartridge 201, the middle filter cartridge 202, and the inner filter cartridge 203 are coaxially arranged. The bottom surface of the outer filter cartridge 201 is rotatably connected to the upper surface of the transparent viewing window 102 located above and is simultaneously fixedly connected to the output shaft of the drive device. The outer filter cartridge 201, the middle filter cartridge 202, and the inner filter cartridge 203 are integrally formed, and two packing gaps are formed between the three. The two packing gaps are filled with different adsorption materials.

[0027] The outer filter cartridge 201, middle filter cartridge 202, and inner filter cartridge 203 are coaxially arranged and integrally formed, ensuring structural stability. The bottom surface of the outer filter cartridge 201 is rotatably connected to the upper surface of the upper partition plate 101 and fixedly connected to the output shaft of the drive device, driven by the motor 209. The two packing gaps formed between the three are filled with different adsorption materials, such as activated carbon for adsorbing organic matter and ion exchange resin for removing heavy metal ions. Wastewater enters the inner filter cartridge 203 through the inlet channel 103. During the rotation of the filter cartridge, the wastewater passes through the inner filter cartridge 203, the middle filter cartridge 202, and the outer filter cartridge 201 in sequence. When passing through the filter holes of each stage of the filter cartridge, large particles of impurities are intercepted, and at the same time, the wastewater comes into full contact with the adsorption material in the packing gaps, and the pollutants are adsorbed and removed. The multi-stage filter cartridge increases the number of filtration and adsorption levels, improving the pretreatment effect. Different adsorption materials can remove different types of pollutants, expanding the applicability of the pretreatment. The rotation of the filter cartridge allows the wastewater to come into more thorough contact with the adsorption material, improving adsorption efficiency. At the same time, centrifugal force is used to distribute impurities in the wastewater more evenly on the surface of the filter cartridge, further enhancing the filtration effect.

[0028] Furthermore, the filter holes on the outer wall of the outer filter cartridge 201, the middle filter cartridge 202, and the inner filter cartridge 203 are arranged from small to large.

[0029] Larger pores are formed on the inner filter cartridge 203 for initial filtration of larger particles. The middle filter cartridge 202 has smaller pores than the inner cartridge 203, further filtering smaller particles. The outer filter cartridge 201 has the smallest pores, trapping even finer impurities. The pores can be designed to be circular or elliptical, evenly distributed around the outer wall of the filter cartridge. The spacing between the pores is determined by the strength of the filter cartridge and filtration requirements. This staged filtration method gradually removes impurities of different sizes, preventing large particles from clogging the small-pore filter cartridges, improving filtration efficiency and extending the lifespan of the filter cartridges. Simultaneously, this design ensures that the pretreated wastewater better meets the influent requirements of the membrane module separation unit 3, reducing damage to the membrane module and guaranteeing membrane separation performance.

[0030] Furthermore, a cover 204 is detachably connected to the top of the outer filter cartridge 201. A connection hole 205 is provided in the middle of the cover 204. The bottom end of the water inlet channel 103 passes through the cover 204 through the connection hole 205 and extends into the inner filter cartridge 203.

[0031] The cover 204 is made of the same or compatible material as the filter cartridge and is detachably connected to the top of the outer filter cartridge 201 via threaded connection, snap-fit ​​connection, or flange connection. The connecting hole 205 is located in the middle of the cover 204, and its diameter is slightly larger than the outer diameter of the inlet channel 103, ensuring that the inlet channel 103 can pass through tightly. When installing the inlet channel 103, a rotating seal can be installed between the connecting hole 205 and the inlet channel 103. This ensures the sealing of the connection without affecting the independent rotation of the multi-stage filter cartridges, preventing sewage leakage. The detachable design of the cover 204 facilitates the inspection, cleaning, and replacement of the adsorbent material inside the filter cartridge. The connecting hole 205 makes the connection between the inlet channel 103 and the filter cartridge more secure and ensures that sewage can smoothly enter the filter cartridge for pretreatment, while preventing sewage leakage at the connection point, which would affect the treatment effect.

[0032] Furthermore, the upper surface of the cylinder cover 204 is provided with several evenly distributed insertion holes 206, each insertion hole 206 is fitted with a fastener 207, and one end of each fastener 207 is threaded into a corresponding threaded connection hole 208. Several threaded connection holes 208 are provided on the upper end face of the outer filter cylinder 201.

[0033] A number of evenly spaced insertion holes 206 are made around the circumference of the upper surface of the cover 204. The number and distribution of the insertion holes 206 are determined according to the size and strength requirements of the cover 204. Corresponding threaded connection holes 208 are made on the upper end face of the outer filter cartridge 201. Fasteners 207 can be bolts or screws; one end is inserted into the insertion hole 206, and then tightened to make it threadedly connected in the threaded connection hole 208. When installing the fasteners 207, an appropriate amount of thread sealant can be applied to the threads to enhance the sealing and tightness of the connection. This connection method makes the connection between the cover 204 and the outer filter cartridge 201 more secure and reliable, capable of withstanding the centrifugal force generated when the filter cartridge rotates and the pressure of sewage, preventing the cover 204 from loosening and causing sewage leakage or damage to the internal structure of the filter cartridge. At the same time, it facilitates the disassembly of the cover 204 for maintenance when necessary.

[0034] Furthermore, the driving device is a motor 209, which is fixedly installed in a sealed mounting box 108. The sealed mounting box 108 is located on the bottom surface of the upper partition 101. One end of the output shaft of the motor 209 extends through an extension hole opened on the surface of the partition 101 to the other side of the partition 101 and is fixedly connected to the bottom surface of the outer filter cartridge 201.

[0035] The motor 209 is fixedly installed in the sealed mounting box 108, which is made of corrosion-resistant materials such as stainless steel or engineering plastics. The sealed mounting box 108 is installed on the bottom surface of the upper partition 101 to prevent the motor 209 from being corroded by sewage. The output shaft of the motor 209 extends to the other side of the partition 101 through an extension hole on its surface and is fixedly connected to the bottom surface of the outer filter cartridge 201. A key connection, welding, or coupling can be used to ensure the stability of the connection.

[0036] Please see Figure 2 The oxidation treatment unit 4 includes several ozone aeration heads 401. Each ozone aeration head 401 is detachably installed in a corresponding sealing mounting hole 106. Several sealing mounting holes 106 are opened on the inner wall of the bottommost strong part. One end of each ozone aeration head 401 extends to the outside of the outer shell 1 through the corresponding sealing mounting hole 106 and communicates with the upper surface of the gas collection box 402. One end of the connecting pipe 403 is connected to the bottom surface of the gas collection box 402. The other end of the connecting pipe 403 is connected to the output end of the ozone generator 404. The ozone generator 404 is fixedly installed on one side surface of the outer shell 1.

[0037] The ozone aerator head 401 is made of a corrosion-resistant material with uniform micropores, such as sintered titanium alloy microporous material. Each ozone aerator head 401 is detachably installed in a sealed mounting hole 106, which is located on the inner wall of the bottom of the lowest chamber. The two are sealed with sealant or a gasket to prevent wastewater leakage. One end of the ozone aerator head 401 extends through the sealed mounting hole 106 to the outside of the outer casing 1, connecting to the upper surface of the gas collection box 402, which collects and distributes ozone. A connecting pipe 403 connects the gas collection box 402 to the output end of the ozone generator 404, which is fixedly installed on one side of the outer casing 1. The ozone output of the ozone generator 404 is adjusted according to the treated water volume and pollutant concentration. The ozone aerator head 401 uniformly introduces ozone into the water in the form of microbubbles, increasing the contact area between ozone and water, improving the oxidation efficiency of ozone, and more effectively degrading residual new pollutants, thus improving the quality of the effluent. The detachable installation method facilitates the maintenance and replacement of the ozone aeration head 401, ensuring the normal operation of the oxidation treatment unit 4.

[0038] Furthermore, several ozone aerators 401 are evenly distributed in a ring.

[0039] Based on the size and shape of the bottom chamber, the installation positions of the ozone aerators 401 are determined on the inner wall of the bottom, ensuring a uniform ring-shaped distribution. The distance between adjacent ozone aerators 401 is determined according to the ozone diffusion range and treatment effect requirements, ensuring that ozone can evenly cover the entire chamber. During installation, ensure that the installation angle of each ozone aerator 401 is consistent, allowing ozone bubbles to diffuse vertically upwards and avoiding uneven ozone distribution. The uniformly distributed ring-shaped ozone aerators 401 make the ozone distribution in the water more uniform, avoiding localized excessively high or low ozone concentrations, ensuring the comprehensiveness and consistency of oxidation treatment, thereby more effectively removing residual new pollutants and improving the stability of the treatment effect.

[0040] Furthermore, an ultraviolet lamp is fixedly installed on the bottom surface of the lower partition 101.

[0041] Select a suitable ultraviolet (UV) lamp for water treatment; the power and wavelength are determined based on the treatment volume and water quality requirements. The UV lamp is fixedly installed on the bottom surface of the lower partition 101 using a bracket or mounting base, ensuring stability and effective irradiation of the water in the lower chamber. Direct impact of water on the UV lamp should be avoided; protective devices can be installed around it. The UV lamp works in conjunction with the ozone aerator 401. UV irradiation promotes ozone decomposition, generating more hydroxyl radicals and enhancing oxidation capacity. Simultaneously, some new pollutants can undergo photolysis under UV light, improving the degradation effect. Furthermore, UV light can inactivate residual microorganisms in the water, further enhancing the safety of the effluent.

[0042] Working principle: Wastewater enters the pretreatment adsorption unit 2 through the inlet channel 103 at the top of the outer shell 1. The outer filter cartridge 201, the middle filter cartridge 202 and the inner filter cartridge 203 rotate under the drive of the motor 209. The filter holes of different filter cartridges are used to filter large particulate impurities in stages. [1] At the same time, the adsorption material in the gap between the filter cartridges adsorbs pollutants, reducing the treatment pressure of the membrane module separation unit 3. The pretreated wastewater flows into the membrane module separation unit 3 in the middle chamber through the communication port 105 of the upper partition 101 for separation treatment to remove new pollutants and other impurities in the water. The treated water enters the oxidation treatment unit 4 in the lowest chamber. The ozone generated by the ozone generator 404 is evenly introduced into the water in the form of micro bubbles through the ozone aeration head 401 to oxidize and degrade the residual new pollutants. The ultraviolet lamp located on the bottom surface of the lower partition 101 works in synergy with the ozone to further decompose the new pollutants and inactivate microorganisms. Finally, the treated water is discharged from the drainage channel 104, realizing the efficient removal and purification of new pollutants in wastewater.

[0043] It should be noted that the specific models and specifications of the motor 209, membrane module separation unit 3, and ozone generator 404 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The power supply and operating principle of the motor 209, the membrane module separation unit 3, and the ozone generator 404 are clear to those skilled in the art and will not be described in detail here.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
