An adjusting component is installed on the support assembly, and a driving component and a control component are installed on the membrane module to control the adjusting and driving components. Thus, the membrane module is tightened or loosened under the action of the adjusting component, making it difficult for sludge to adhere firmly to the membrane module surface; the driving component causes the membrane module to vibrate, increasing the possibility of sludge detaching from the membrane module surface.

Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device and treatment method thereof. Background Technology

[0002] Industrial wastewater originates from a wide range of industries, including chemical, printing and dyeing, papermaking, food processing, and pharmaceuticals. Therefore, the wastewater requiring treatment is complex in quality, with numerous types of pollutants, high concentrations, high toxicity, and difficulty in degradation. Existing wastewater treatment technologies mainly include oxidation technologies such as Fenton oxidation and separation technologies such as membrane separation. Membrane separation technology primarily uses different types of membranes, such as microporous membranes, ultrafiltration membranes, and nanofiltration membranes, to filter pollutants from wastewater, thereby achieving pollutant removal.

[0003] In related technologies, membrane modules for wastewater treatment are prone to fouling due to contaminant adhesion during operation, requiring regular cleaning to maintain membrane permeability and treatment efficiency. Currently, aeration cleaning is used to mitigate membrane fouling, primarily by introducing air bubbles into the bottom of the membrane module. The collision of these bubbles with the membrane fibers creates a shaking effect, accelerating the removal of contaminants from the membrane module.

[0004] However, the above-mentioned methods for cleaning membrane modules have low cleaning efficiency, which affects the filtration effect of the membrane modules and makes it difficult to reduce the concentration of pollutants in wastewater. Summary of the Invention

[0020] In one possible implementation, a first separator and a second separator are arranged sequentially from the inside to the outside of the box; the inner wall of the first separator forms the membrane separation zone, the outer wall of the first separator and the inner wall of the second separator form the neutralization zone, and the outer wall of the second separator and the inner wall of the box form the reaction zone.

[0021] The membrane separation zone is connected to the neutralization zone via the first separator, and the neutralization zone is connected to the reaction zone via the second separator;

[0022] The support assembly is disposed on the inner wall of the first separator.

[0023] In one possible implementation, the reaction region includes an acidification sub-region and a reaction sub-region connected to the acidification sub-region, and the reaction sub-region is connected to the neutralization region;

[0026] In one possible implementation, the reaction zone further includes a third partition, the outer wall of which, together with the inner wall of the housing, forms the acidification sub-zone, and the inner wall of which, together with the outer wall of the second partition, forms the reaction sub-zone.

[0027] The acidification sub-region is connected to the reaction sub-region via the third separator; the reaction sub-region is connected to the neutralization sub-region via the second separator;

[0028] The tank is equipped with a water inlet assembly, through which the wastewater enters the acidification sub-region;

[0036] Secondly, this application provides a wastewater treatment method for any of the aforementioned wastewater treatment devices, the treatment method comprising:

[0037] Wastewater is injected into the reaction zone of the wastewater treatment device, where the reaction mechanism oxidizes the wastewater. The oxidized wastewater then enters the neutralization zone of the wastewater treatment device, where the neutralization mechanism neutralizes the wastewater. The neutralized wastewater then enters the membrane separation zone of the wastewater treatment device, where the membrane module of the membrane separation mechanism filters the sludge from the wastewater.

[0038] The control component of the membrane separation mechanism controls the adjustment component to tighten or loosen the membrane module, and controls the drive component to vibrate the membrane module so that the sludge on the membrane module falls off.

[0039] This application provides a wastewater treatment device and method. The wastewater treatment device includes a tank and a treatment structure. A membrane separation zone, a neutralization zone, and a reaction zone are sequentially connected and spaced apart within the tank, so that the membrane separation mechanism, neutralization mechanism, and reaction mechanism of the treatment structure are respectively located within the membrane separation zone, neutralization zone, and reaction zone. Wastewater is introduced into the reaction zone, where it is oxidized by the reaction mechanism, neutralized by the neutralization mechanism in the neutralization zone, and finally enters the membrane separation zone. A support assembly is provided within the membrane separation zone, and a membrane module is mounted on the support assembly for filtering sludge from the wastewater entering the membrane separation zone. An adjusting component is provided on the support assembly to move the support assembly closer or further apart. A driving component is provided on the membrane module to vibrate the membrane module. A control component is provided to control the adjusting component and the driving component. Therefore, when the membrane module in the membrane separation zone needs cleaning due to sludge adhesion, the control unit is activated to control the adjusting component to move the support components closer or further apart, thereby tightening or loosening the membrane module on the support components. This causes deformation of the membrane module surface, reducing the effective contact area between the sludge and the membrane module surface, making it difficult for the sludge to adhere firmly to the membrane module surface. Furthermore, the control unit controls the drive component to vibrate the membrane module, further weakening the adhesion between the membrane module and the sludge, thus increasing the possibility of sludge detaching from the membrane module surface. In this way, this application improves the cleaning efficiency of sludge adhering to the membrane module by deforming the membrane module and applying external vibration force, thereby accelerating the restoration of membrane module permeability, ensuring the filtration effect of the membrane module on sludge in wastewater, and ultimately reducing the concentration of pollutants in the wastewater.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application and how they solve the aforementioned technical problems will be clearly and completely described below with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0053] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0054] Industrial wastewater originates from a wide range of industries, including chemical, printing and dyeing, papermaking, food processing, and pharmaceuticals. The processes in these industries vary significantly, resulting in complex wastewater quality characterized by a wide variety of pollutants, high concentrations, high toxicity, and poor biodegradability. With increasingly stringent industrial wastewater discharge standards, conventional physicochemical and biological treatment technologies alone are insufficient to guarantee consistently compliant effluent. Existing wastewater treatment technologies primarily include oxidation technologies such as Fenton oxidation and separation technologies such as membrane separation. Membrane separation technology mainly uses different types of membranes, such as microporous membranes, ultrafiltration membranes, and nanofiltration membranes, to filter pollutants from wastewater, thereby achieving pollutant removal.

[0055] In related technologies, membrane modules for wastewater treatment are prone to fouling due to contaminant adhesion during operation, requiring regular cleaning to maintain membrane permeability and treatment efficiency. Currently, aeration cleaning is used to mitigate membrane fouling, primarily by introducing air bubbles into the bottom of the membrane module. The collision of these bubbles with the membrane fibers creates a shaking effect, accelerating the removal of contaminants from the membrane module. However, this method of cleaning membrane modules has low cleaning efficiency, affecting the filtration effect and making it difficult to reduce the concentration of contaminants in the wastewater.

[0056] Therefore, this application provides a wastewater treatment device and method thereof. The wastewater treatment device includes a tank and a treatment structure. A membrane separation zone, a neutralization zone, and a reaction zone are sequentially connected and spaced apart within the tank, so that the membrane separation mechanism, neutralization mechanism, and reaction mechanism of the treatment structure are respectively located within the membrane separation zone, neutralization zone, and reaction zone. Wastewater is introduced into the reaction zone, where it is oxidized by the reaction mechanism, neutralized by the neutralization mechanism in the neutralization zone, and finally enters the membrane separation zone. A support assembly is provided within the membrane separation zone, and a membrane module is mounted on the support assembly for filtering sludge from the wastewater entering the membrane separation zone. An adjusting component is provided on the support assembly to move the support assembly closer or further apart. A driving component is provided on the membrane module for vibrating the membrane module. A control component is provided to control the adjusting component and the driving component. Therefore, when the membrane module in the membrane separation zone needs cleaning due to sludge adhesion, the control unit is activated to control the adjusting component to move the support components closer or further apart, thereby tightening or loosening the membrane module on the support components. This causes deformation of the membrane module surface, reducing the effective contact area between the sludge and the membrane module surface, making it difficult for the sludge to adhere firmly to the membrane module surface. Furthermore, the control unit controls the drive component to vibrate the membrane module, further weakening the adhesion between the membrane module and the sludge, thus increasing the possibility of sludge detaching from the membrane module surface. In this way, this application improves the cleaning efficiency of sludge adhering to the membrane module by deforming the membrane module and applying external vibration force, thereby accelerating the restoration of membrane module permeability, ensuring the filtration effect of the membrane module on sludge in wastewater, and ultimately reducing the concentration of pollutants in the wastewater.

[0057] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0058] like Figures 1 to 3 As shown, this application provides a wastewater treatment device, including a housing 100 and a treatment structure 200. The housing 100 has a membrane separation zone 110, a neutralization zone 120 and a reaction zone 130 arranged and connected sequentially from the inside to the outside. Wastewater is introduced into the reaction zone 130.

[0059] The processing structure 200 includes a reaction mechanism 210, a neutralization mechanism 220 and a membrane separation mechanism 230, with the reaction mechanism 210 and the neutralization mechanism 220 located in the reaction zone 130 and the neutralization zone 120, respectively.

[0060] The reaction unit 210 is used to oxidize wastewater and transport the oxidized wastewater to the neutralization zone 120; the neutralization unit 220 is used to neutralize wastewater and transport the neutralized wastewater to the membrane separation zone 110.

[0061] The membrane separation mechanism 230 includes a control component and a membrane module 231, a support component 232, an adjustment component 233, and a drive component 234 disposed in the membrane separation zone 110. The membrane module 231 and the adjustment component 233 are both disposed on the support component 232, and the drive component 234 is disposed on the membrane module 231. Both the adjustment component 233 and the drive component 234 are electrically connected to the control component.

[0062] Membrane module 231 is used to filter sludge from wastewater entering membrane separation zone 110.

[0063] The control element is configured to control the adjustment element 233 to move the support components 232 away from or closer to each other, thereby tightening or loosening the membrane assembly 231, and to control the drive element 234 to drive the membrane assembly 231 to vibrate.

[0064] In this application, exemplarily, the housing 100 is a cylindrical structure, and along the diameter of the cylindrical housing 100, a membrane separation zone 110, a neutralization zone 120, and a reaction zone 130 are sequentially arranged from the center to the circumference, that is, the membrane separation zone 110, the neutralization zone 120, and the reaction zone 130 are coaxially arranged, and the membrane separation zone 110, the neutralization zone 120, and the reaction zone 130 are sequentially connected. The reaction zone 130 is used to introduce external wastewater that needs to be treated. It should be noted that the housing 100 can also be a rectangular structure, etc. This application embodiment does not impose specific limitations on this, as long as the housing 100 is a hollow structure, multiple partitions can be arranged at intervals.

[0065] In a specific configuration, the reaction mechanism 210 is located within the reaction zone 130. For example, the reaction mechanism 210 includes a Fenton reaction catalyst and an aerator 300, with the aerator 300 located at the bottom of the reaction zone 130. In a specific implementation, an acidic agent is added to the reaction zone 130 to make the incoming wastewater acidic. Ferrous sulfate and hydrogen peroxide are also added to the reaction zone 130 to ensure that the catalyst, ferrous sulfate, and hydrogen peroxide are fully mixed with the wastewater in the reaction zone 130 under the aeration action of the aerator 300. This catalyzes the generation of active oxygen from the hydrogen peroxide, which breaks down the molecular structure of recalcitrant organic matter in the wastewater, oxidizing large organic molecules into smaller ones or mineralizing them, and reacting with iron ions to form sludge. It should be noted that the oxidized wastewater, mixed with sludge, flows into the neutralization zone 120.

[0066] By adding an alkaline agent to the neutralization zone 120, the pH value of the wastewater flowing into the neutralization zone 120 is restored to neutral. The neutralization mechanism 220 is located within the neutralization zone 120. For example, the neutralization mechanism 220 includes an aerator 300. The aeration action of the aerator 300 intensifies the molecular motion within the wastewater, thereby removing residual hydrogen peroxide and air bubbles. It should be noted that the neutralized wastewater, mixed with sludge, flows into the membrane separation zone 110.

[0067] By installing a membrane module 231 within the membrane separation zone 110, exemplarily a polyvinylidene fluoride (PVDF) multilayer membrane, the porous structure of the membrane allows wastewater entering the membrane separation zone 110 to pass through while preventing sludge from passing through, thereby achieving the separation of neutralized wastewater and sludge and reducing the concentration level of pollutants in the wastewater. It should be noted that the membrane module 231 can also be other types of membranes; this application embodiment does not impose excessive limitations, and the specific design can be adaptively set according to factors such as the type, concentration, and particle size of pollutants in the wastewater.

[0068] It is understandable that the wastewater filtered by the membrane module 231 is the treated clean water. The treated clean water can be discharged outside the tank 100 by a water collection device installed on the membrane module 231, and then collected for further application.

[0069] In this application, a support assembly 232 is provided in the membrane separation zone 110, and a membrane assembly 231 is disposed on the support assembly 232. An adjustment member 233 is provided on the support assembly 232. For example, the adjustment member 233 can be a hydraulic component or an electric motor or other structural component, used to drive the support assembly 232 to move away from or closer to each other. In addition, a drive member 234 is provided on the membrane assembly 231. For example, the drive member 234 can be a vibrator or other structural component, used to drive the membrane assembly 231 to vibrate.

[0070] In this embodiment, at least one control element (not shown in the figure) is provided, and both the adjusting element 233 and the driving element 234 are electrically connected to the control element. For example, the control element can be a push-button switch or a controller, etc., and the operation of the control element controls the operating state of the adjusting element 233 and the driving element 234. It is understood that the operating state of the adjusting element 233 and the driving element 234 is not limited to being on or off, but can also include other control states such as operating speed and operating time. However, it should be noted that when the adjusting element 233 adjusts the membrane assembly 231 to a tensioned state, excessive tension should be avoided to prevent affecting the filtration effect of the membrane assembly 231. The control parameters of the adjusting element 233 and the driving element 234 are not specifically limited in this embodiment, and can be adaptively set according to actual usage requirements.

[0071] In practical applications, the membrane module 231 in the membrane separation zone 110 is in operation for extended periods, leading to sludge buildup. By installing a pressure sensor in the separation zone to monitor pressure changes on the membrane module 231, blockage can be detected promptly. When blockage occurs and cleaning of the membrane module 231 is required, the control unit is activated to control the adjusting component 233 to move the support component 232 closer or further apart, thereby tightening or loosening the membrane module 231 on the support component 232. This causes deformation of the membrane module 231 surface, reducing the effective contact area between the sludge and the membrane module 231 surface, making it difficult for the sludge to adhere firmly. Furthermore, the control unit controls the driving component 234 to vibrate the membrane module 231, further weakening the adhesion between the membrane module 231 and the sludge, increasing the likelihood of sludge detaching from the membrane module 231 surface, and thus improving the permeability of the membrane module 231. In this way, by deforming the membrane module 231 and applying vibrational force, the cleaning efficiency of the sludge attached to the membrane module 231 is improved, thereby accelerating the restoration of the permeability of the membrane module 231, ensuring the filtration effect of the membrane module 231 on the sludge in the wastewater, and thus reducing the concentration of pollutants in the wastewater.

[0072] In some embodiments, the support component 232 includes a first support member 2321 and a second support member 2322, which are spaced apart within the membrane separation zone 110.

[0073] Both ends of the membrane module 231 and both ends of the adjusting member 233 are respectively disposed on the first support member 2321 and the second support member 2322.

[0074] In this application, as Figure 2 and Figure 3 As shown, by way of example, a fixing plate is provided in the height direction of the membrane separation zone 110 by welding or integral molding. The first support member 2321 and the second support member 2322 are spaced apart on the fixing plate, and both the first support member 2321 and the second support member 2322 can slide relative to the fixing plate.

[0075] In a specific configuration, the membrane assembly 231 is fixed to the first support member 2321 and the second support member 2322 by bonding or clamping. In addition, the two ends of the adjusting member 233 are respectively fixed to the first support member 2321 and the second support member 2322. For example, the adjusting member 233 is an electric telescopic rod. Thus, when the electric telescopic rod is shortened, it causes the first support member 2321 and the second support member 2322 to slide relative to the fixed plate and move closer to each other, thereby making the membrane assembly 231 in a relaxed state. When the electric telescopic rod is extended, it causes the first support member 2321 and the second support member 2322 to slide relative to the fixed plate and move away from each other, thereby making the membrane assembly 231 in a tensile state.

[0076] By setting the first support member 2321 and the second support member 2322, it is convenient to install the membrane module 231 and the adjusting member 233, and the membrane module 231 is easy to deform under the adjustment of the adjusting member 233, thereby reducing the effective contact area between the sludge and the surface of the membrane module 231, making it difficult for the sludge to adhere firmly to the surface of the membrane module 231, thereby improving the cleaning efficiency of the sludge adhering to the membrane module 231.

[0077] In some embodiments, the membrane module 231 includes a plurality of membrane fibers 2311 and a catalyst disposed on the membrane fibers 2311. Each membrane fiber 2311 is sequentially and spaced apart on the support component 232. The catalyst is used to catalytically oxidize organic matter in wastewater entering the membrane separation zone 110.

[0078] In this application, as Figure 3 As shown, the membrane module 231 includes a plurality of membrane fibers 2311, which are sequentially and spaced apart on the first support member 2321 and the second support member 2322 by means of bonding or other methods. For example, the membrane fibers 2311 can be microfiltration membrane fibers, ultrafiltration membrane fibers, nanofiltration membrane fibers, etc., and the specific type of membrane fiber 2311 can be selected according to the type and particle size adaptability of pollutants in wastewater treatment.

[0079] In a specific configuration, a catalyst is loaded onto the membrane fiber 2311. For example, the catalyst is a catalyst material. By loading the catalyst material, the surface of the membrane fiber 2311 is modified, so that the membrane fiber 2311 can have both filtration and catalytic functions.

[0080] In this way, when the membrane fiber 2311 filters wastewater and sludge, the membrane fiber 2311 enriches the residual pollutants and further degrades the pollutants through the catalyst material on the surface of the membrane fiber 2311, and consumes the hydrogen peroxide that was not completely removed from the wastewater in the neutralization zone 120, so as to ensure that the water quality after separation by the membrane fiber 2311 is good.

[0081] In some embodiments, the membrane separation mechanism 230 further includes a cleaning component 235 and a reflux component 236; the cleaning component 235 includes a first cleaning channel 2351 and a second cleaning channel 2352, one end of the first cleaning channel 2351 is connected to the membrane component 231 and the other end is connected to the backwash component 237; one end of the second cleaning channel 2352 is connected to the membrane component 231 and the other end is connected to the chemical cleaning component 238.

[0082] The reflux assembly 236 includes at least one reflux pipe 2361 and at least one reflux pump 2362 disposed on the reflux pipe 2361. The two ends of the reflux pipe 2361 are located in the reaction zone 130 and the membrane separation zone 110, respectively. The reflux pump 2362 is used to reflux a portion of the sludge in the membrane separation zone 110 back to the reaction zone 130 via the reflux pipe 2361.

[0083] In this application, as Figure 1 and Figure 2 As shown, the first cleaning channel 2351 is at least one first cleaning tube, one end of which extends into the membrane separation zone 110, and the other end is connected to the backwash assembly 237. For example, the backwash assembly 237 can be at least one of the backwash water component 2371 and the backwash gas component 2372.

[0084] In specific implementation, the backwash component 2371 consists of a water pump and a water supply pipeline connected together, and the water supply pipeline is connected to the first cleaning pipe. The water pump is used to draw external clean water and deliver the clean water to the first cleaning pipe through the water supply pipeline, so that the first cleaning pipe can pass through the water pressure backwash membrane assembly 231. The backair wash component 2372 consists of a fan and an air supply pipeline connected together, and the air supply pipeline is connected to the first cleaning pipe. The fan is connected to the external environment for exhausting air and delivers air to the first cleaning pipe through the air supply pipeline, so that the first cleaning pipe can pass through the air pressure backwash membrane assembly 231.

[0085] In this embodiment, there are two first cleaning tubes, which are respectively connected to the backwash component 2371 and the backwash component 2372. Thus, when the membrane module 231 is cleaned by the adjusting component 233 and the driving component 234, the backwash component 237 can be used for auxiliary cleaning to accelerate the removal of sludge from the membrane module 231 and thus quickly restore the membrane's permeability.

[0086] In addition, the second cleaning channel 2352 is at least one second cleaning tube, one end of which extends into the membrane separation zone 110 and the other end is connected to the chemical cleaning component 238.

[0087] In practical implementation, the chemical cleaning component 238 consists of a connected chemical cleaning water pump and a chemical cleaning pipeline, with the chemical cleaning pipeline connected to a second cleaning pipe. The chemical cleaning water pump draws chemical cleaning water from an external chemical cleaning water tank and delivers it through the chemical cleaning pipeline to the second cleaning pipe, allowing the second cleaning pipe to wash the membrane module 231 with the chemical cleaning water. Thus, when sludge and other contaminants accumulated on the membrane module 231 cannot be effectively removed by the backwashing component 237, and when the transmembrane pressure difference of the membrane module 231 reaches a set threshold, stubborn contaminants attached to the surface of the membrane module 231 can be removed by chemical cleaning.

[0088] In this application, as Figure 2As shown, one end of the reflux pipe 2361 is inserted into the reaction zone 130, and the other end is inserted into the membrane separation zone 110. Through the reflux pump 2362 installed on the reflux pipe 2361, a portion of the high-concentration sludge concentrated by the membrane module 231 in the membrane separation zone 110 is refluxed back into the reaction zone 130. This enhances the crystal growth on the surface of the Fenton reaction catalyst in the reaction zone 130, thereby generating more active oxygen in a shorter time and shortening the oxidation reaction time in the reaction zone 130.

[0089] In some embodiments, a first partition 140 and a second partition 150 are sequentially spaced from the inside to the outside of the housing 100; the inner wall of the first partition 140 forms a membrane separation zone 110, the outer wall of the first partition 140 and the inner wall of the second partition 150 form a neutralization zone 120, and the outer wall of the second partition and the inner wall of the housing 100 form a reaction zone 130.

[0090] The membrane separation zone 110 is connected to the neutralization zone 120 via the first separator 140, and the neutralization zone 120 is connected to the reaction zone 130 via the second separator 150.

[0091] The support component 232 is disposed on the inner wall of the first separator 140.

[0092] The first partition 140 and the second partition 150 are both annular, and are arranged circumferentially around the center of the cylindrical box 100, with the first partition 140 and the second partition 150 surrounding the box 100. It should be noted that the first partition 140 and the second partition 150 can also be rectangular structures, etc. This embodiment is merely illustrative; the key is to ensure that the first partition 140 and the second partition 150 are matched with the box 100 and function as partitions within the box 100.

[0093] In a specific configuration, the inner wall of the first separator 140, i.e. the side of the first separator 140 facing the axis of the housing 100, is used to form the membrane separation zone 110. It can be understood that the area between the first separator 140 and the second separator 150 forms the neutralization zone 120, and the area between the second separator 150 and the inner wall of the housing 100 forms the reaction zone 130.

[0094] In this embodiment of the application, the first support member 2321 and the second support member 2322 respectively abut against the inner wall of the first partition member 140. For example, the first partition member 140 is provided with a sliding groove, and the abutting ends of the first support member 2321 and the second support member 2322 and the first partition member 140 are slidably inserted into the sliding groove. In this way, the first support member 2321 and the second support member 2322 can be installed in the membrane separation zone 110, and the first support member 2321 and the second support member 2322 can slide up and down relative to the first partition member 140 under the action of the adjusting member 233, thereby causing the membrane assembly 231 to be tightened or loosened.

[0095] In specific implementation, the first separator 140 is provided with at least one first water passage hole, and the second separator 150 is provided with at least one second water passage hole, so that the wastewater and sludge oxidized in the reaction zone 130 enter the neutralization zone 120 through the second water passage hole, and the wastewater and sludge neutralized in the neutralization zone 120 enter the membrane separation zone 110 through the first water passage hole for mud-water separation.

[0096] In some embodiments, the reaction zone 130 includes an acidification sub-zone 131 and a reaction sub-zone 132 connected to the acidification sub-zone 131, and the reaction sub-zone 132 is connected to the neutralization zone 120; the acidification sub-zone 131 is used to introduce wastewater and to transport the acidified wastewater to the reaction sub-zone 132.

[0097] The reaction mechanism 210 is located in the reaction sub-region 132 to oxidize the wastewater in the reaction sub-region 132 and transport the oxidized wastewater to the neutralization region 120.

[0098] In this application, as Figure 1 and Figure 2 As shown, the reaction zone 130 includes an acidification sub-zone 131 and a reaction sub-zone 132 that are connected. Specifically, the acidification sub-zone 131 has an acid reagent inlet and an annular water distributor 183 is provided at the bottom of the acidification sub-zone 131; the reaction sub-zone 132 has inlets for ferrous sulfate and hydrogen peroxide, and the reaction mechanism 210 is located in the reaction sub-zone 132. For example, the reaction mechanism 210 includes a Fenton reaction catalyst and an aerator 300.

[0099] In practical use, the wastewater to be treated from outside enters the acidification sub-zone 131 evenly through the annular water distributor 183. The acidification sub-zone 131 provides an independent acidification environment for the wastewater, ensuring thorough acidification. The acidified wastewater then enters the reaction sub-zone 132 where an oxidation reaction occurs. Active oxygen breaks down the molecular structure of recalcitrant organic matter in the wastewater, oxidizing large organic molecules into smaller ones or mineralizing them, and reacting with iron ions to form sludge. It should be noted that the oxidized wastewater, mixed with sludge, flows into the neutralization zone 120.

[0100] In this embodiment of the application, the acidification sub-region 131 is also equipped with an acid-base monitoring instrument 400 to monitor the acid-base level of the wastewater in the acidification sub-region 131 in real time, so as to ensure that the wastewater reaches the acidification standard when it enters the reaction sub-region 132, thereby ensuring that a sufficient oxidation reaction is carried out in the reaction sub-region 132.

[0101] In this embodiment, the reaction sub-region 132 is further provided with an oxidation-reduction potential monitor 500, which monitors the changes in oxidation-reduction potential in the wastewater to determine whether the dosage of the reagent is appropriate, thereby optimizing the wastewater treatment effect.

[0102] In some embodiments, the reaction zone 130 further includes a third partition 160, the outer wall of the third partition 160 and the inner wall of the housing 100 forming an acidification sub-zone 131, and the inner wall of the third partition 160 and the outer wall of the second partition 150 forming a reaction sub-zone 132.

[0103] The acidification sub-region 131 is connected to the reaction sub-region 132 via the third separator 160; the reaction sub-region 132 is connected to the neutralization sub-region 120 via the second separator 150.

[0104] The tank 100 is equipped with a water inlet assembly 180, through which wastewater enters the acidification sub-zone 131.

[0105] The reaction mechanism 210 includes an interceptor 211, at least one limiting member 212, and multiple carriers 213. The limiting member 212 is slidably disposed on at least one of the second separator 150 and the third separator 160. Each carrier 213 is located within the limiting member 212, and the limiting member 212 is in communication with the reaction sub-region 132. The carriers 213 are used to oxidize wastewater.

[0106] Interceptor 211 is located at the junction of reaction sub-region 132 and neutralization region 120.

[0107] In this application, as Figure 1 and Figure 2 As shown, by way of example, the third partition 160 is also annular and is arranged around the reaction zone 130. Thus, the side of the third partition 160 facing the inner wall of the housing 100 and the inner wall of the housing 100 are used to form the acidification sub-zone 131. It can be understood that the area between the third partition 160 and the second partition 150 forms the reaction sub-zone 132.

[0108] In specific implementation, the tank 100 is equipped with a water inlet assembly 180, which includes at least one water inlet pipe 181 and a water inlet pump 182 installed on the water inlet pipe 181. Wastewater is stored in a wastewater tank. One end of the water inlet pipe 181 is inserted into the wastewater tank, and the other end is connected to the acidification sub-zone 131 of the tank 100. The water inlet pipe 181 is connected to the water distributor 183 in the acidification sub-zone 131. Thus, under the suction action of the water inlet pump 182, the wastewater is evenly injected from the wastewater tank into the acidification sub-zone 131 for acidification treatment.

[0109] By providing at least one third water passage on the third partition 160, so that the wastewater that has been fully acidified in the acidification sub-region 131 can enter the reaction sub-region 132 through the third water passage, it can be understood that the wastewater and sludge that have been oxidized in the reaction sub-region 132 can enter the neutralization zone 120 through the second water passage.

[0110] In this embodiment, the reaction mechanism 210 includes multiple supports 213. Exemplarily, the supports 213 are made of high-density polyethylene or melamine sponge, and a catalyst layer is pre-formed on the surface of the supports 213. The catalyst layer contains at least one metal of iron, manganese, copper, cobalt, cerium, nickel, or an oxide thereof. This facilitates the suspension of the supports 213 within the reaction sub-region 132, enabling homogeneous Fenton reactions and heterogeneous Fenton-like reactions with wastewater, ferrous sulfate, and hydrogen peroxide.

[0111] In this embodiment of the application, the reaction mechanism 210 further includes an interceptor 211. For example, the interceptor 211 is a structural component such as a screen. The screen is set at the connection between the reaction sub-region 132 and the neutralization region 120, that is, the screen covers the second water passage hole on the second separator 150.

[0112] In this way, after the suspended carrier 213 reacts with the wastewater in the reaction sub-zone 132, when the wastewater flows into the neutralization zone 120 through the second water passage, the suspended carrier 213 can remain in the reaction sub-zone 132 under the interception of the net.

[0113] In this embodiment, the reaction mechanism 210 further includes at least one limiting member 212. Specifically, the limiting member 212 includes a limiting portion 2121 and at least one sliding portion 2122 disposed on the limiting portion 2121. For example, the limiting portion 2121 is a retractable net bag for placing the carrier 213, and the sliding portion 2122 is a slider. In addition, a groove 2123 is provided on at least one of the second partition plate and the third partition plate, and the slider is slidably inserted into the groove 2123. It should be noted that the limiting portion 2121 can also be other flexible constraint structures. This embodiment is only provided as an example, and the specific design can be adapted according to the actual use scenario, as long as it is ensured that the limiting portion 2121 can be used to accommodate the carrier 213 and is connected to the reaction sub-region 132.

[0114] In actual use, the suspended carrier 213, ferrous sulfate, and hydrogen peroxide in the reaction zone 132 are fully mixed with the wastewater in the reaction zone 130 under the aeration of the aerator 300, and an oxidation reaction occurs to treat the wastewater.

[0115] By setting the limiting component 212 to limit the range of motion of the suspended carrier 213, the suspended carrier 213 is prevented from accumulating and blocking the interceptor 211. At the same time, by setting the limiting component 212, it is also convenient to replace the suspended carrier 213 as a whole, avoiding the need to retrieve and replace the suspended carrier 213 one by one in the reaction sub-region 132.

[0116] In some embodiments, the neutralization region 120 includes a neutralization sub-region 121 and a degassing sub-region 122 connected to the neutralization sub-region 121. The neutralization sub-region 121 is connected to the reaction sub-region 132, and the degassing sub-region 122 is connected to the membrane separation region 110.

[0117] Neutralization sub-region 121 is used to neutralize the wastewater after oxidation in reaction sub-region 132 and transport the neutralized wastewater to degassing sub-region 122; neutralization mechanism 220 is located in degassing sub-region 122 to degas the wastewater and transport the degassed wastewater to membrane separation sub-region 110.

[0118] In this application, as Figure 1 and Figure 2 As shown, the neutralization zone 120 includes a connected neutralization sub-zone 121 and a degassing sub-zone 122. Specifically, the neutralization sub-zone 121 has an alkaline agent dosing port, and the degassing mechanism is located in the degassing sub-zone 122. For example, the degassing mechanism includes an aerator 300.

[0119] It is understood that the neutralization sub-region 121 is adjacent to the reaction sub-region 132, the degassing sub-region 122 is adjacent to the membrane separation region 110, and the neutralization sub-region 121 is connected to the reaction sub-region 132 through the second water passage on the second separator 150, and the degassing sub-region 122 is connected to the membrane separation region 110 through the first water passage on the first separator 140.

[0120] In practical use, wastewater is introduced into the acidification sub-region 131. The acidified wastewater enters the reaction sub-region 132 to undergo an oxidation reaction, and flows into the neutralization sub-region 121 along with sludge. The neutralization sub-region 121 provides an independent neutralization environment for the wastewater, and the wastewater is fully neutralized by adjusting with alkaline agents. In this embodiment, the neutralization sub-region 121 is also equipped with an acid-base monitoring instrument 400 to monitor the acid-base level of the wastewater in the neutralization sub-region 121 in real time, ensuring that the wastewater reaches the neutralization standard when it enters the degassing sub-region 122.

[0121] After the wastewater's pH value is adjusted to neutral, it flows into the deaeration zone 122. The aeration effect of the aerator 300 intensifies the molecular motion inside the wastewater, thereby removing residual hydrogen peroxide and bubbles from the wastewater. Finally, the neutralized and deaerated wastewater, along with sludge, flows into the membrane separation zone 110.

[0122] In some embodiments, the neutralization region 120 further includes a fourth partition 170, the outer wall of the fourth partition 170 and the inner wall of the second partition 150 forming a neutralization sub-region 121, and the inner wall of the fourth partition 170 and the outer wall of the first partition 140 forming a degassing sub-region 122.

[0123] Neutralization sub-region 121 is connected to degassing sub-region 122 via fourth separator 170; degassing sub-region 122 is connected to membrane separation region 110 via first separator 140.

[0124] The neutralization mechanism 220 includes at least one stirring element 221 and at least one gas dispersing element 222. The stirring element 221 is rotatably disposed within the neutralization sub-region 121 and is disposed adjacent to the gas dispersing element 222.

[0125] In this application, as Figure 1 and Figure 2 As shown, by way of example, the fourth separator 170 is also annular and is disposed around the neutralization zone 120, such that the area between the fourth separator 170 and the second separator 150 forms the neutralization sub-zone 121, and the area between the fourth separator 170 and the first separator 140 forms the degassing sub-zone 122.

[0126] In specific implementation, at least one fourth water passage is provided on the fourth partition 170 so that the wastewater after being fully neutralized in the neutralization sub-region 121 enters the degassing sub-region 122 through the fourth water passage. It can be understood that the wastewater and sludge after being degassed in the degassing sub-region 122 enter the membrane separation zone 110 through the first water passage.

[0127] In this embodiment, the neutralization mechanism 220 includes at least one stirring element 221 and at least one aeration element 222. Exemplarily, the stirring element 221 is a stirring paddle, and the aeration element 222 is an aerator. In a specific configuration, a transmission structure such as a motor is installed at the bottom of the degassing sub-zone 122 to drive the stirring paddle to rotate relative to the degassing sub-zone 122. This ensures that the neutralized wastewater is thoroughly mixed again. Simultaneously, the aerator removes residual hydrogen peroxide and air bubbles from the wastewater to ensure that the treated wastewater meets the required standards.

[0128] In some embodiments, the aeration element 222 may also be an aerator 300 or other device with a degassing function.

[0129] Based on the above embodiments, this embodiment provides a wastewater treatment method for any of the above wastewater treatment devices, the treatment method including:

[0130] Wastewater is injected into the reaction zone 130 of the wastewater treatment device. The reaction mechanism 210 in the reaction zone 130 oxidizes the wastewater. The oxidized wastewater enters the neutralization zone 120 of the wastewater treatment device. The neutralization mechanism 220 in the neutralization zone 120 neutralizes the wastewater. The neutralized wastewater enters the membrane separation zone 110 of the wastewater treatment device. The membrane module 231 of the membrane separation mechanism 230 in the membrane separation zone 110 filters the sludge in the wastewater.

[0131] The control unit 233 of the membrane separation mechanism 230 controls the membrane module 231 to tighten or loosen, and controls the drive unit 234 to drive the membrane module 231 to vibrate, so that the sludge on the membrane module 231 will fall off.

[0132] The structure of the wastewater treatment device has been described in detail in the above embodiments, and will not be repeated here.

[0133] In this embodiment, the membrane module 231 in the membrane separation zone 110 is in operation for a long time, causing sludge to adhere to it. To ensure the permeability of the membrane module 231, during cleaning, the control unit is activated to control the adjusting component 233 to move the supporting component 232 closer or further apart, thereby tightening or loosening the membrane module 231 on the supporting component 232. This causes deformation of the membrane module 231 surface, reducing the effective contact area between the sludge and the membrane module 231 surface, making it difficult for the sludge to adhere firmly to the membrane module 231 surface. In addition, the control unit controls the driving component 234 to vibrate the membrane module 231, further weakening the adhesion between the membrane module 231 and the sludge, thereby increasing the possibility of the sludge detaching from the membrane module 231 surface. In this way, by deforming the membrane module 231 and applying vibrational force, the cleaning efficiency of the sludge adhering to the membrane module 231 is improved.
