Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, specifically to an array type microbial electro - desalination device, especially an array type microbial electro - desalination device for a spiral wound membrane module. Background Technique

[0002] With the development of the environmental protection industry and the improvement of concepts, the control of water pollution has shifted from traditional sewage treatment towards the recovery of resources and energy in sewage, which also requires related technologies to move from small - scale pilot tests to engineering applications. Moreover, with the transformation of the environmental protection industry from pollutant reduction to resource recovery, in the field of municipal sewage, how to efficiently extract energy and resources from raw sewage with low operating costs and how to meet important technical research requirements during the process of technology scaling up have been put forward.

[0003] Bio - electro - desalination / concentration technology utilizes the self - sustaining chemical energy of sewage to generate a directional electric field through the action of electrogenic microorganisms, and specific ions migrate on both sides of the ion - exchange membrane to complete the process of desalination or concentration. Specifically, the principle of this technology is to use energy substances such as COD in municipal sewage, form a directional electric field by using the anode and cathode loaded with electrogenic microorganisms, and complete ion migration under the action of the directional electric field through the ion - exchange membrane to recover or remove ammonia nitrogen, nitrate nitrogen, orthophosphate, etc. in the raw sewage.

[0004] During the process of technology scaling up, membrane winding is a good method. However, how to make each spiral wound membrane module be spatially intensive, the system be arranged orderly and be convenient for regular maintenance has become an urgent problem to be solved. In other words, during the process of technology scaling up, how to systematically integrate the composite spiral wound membrane elements and supporting equipment is an important difficulty in the expansion of this technology. The finished element that completes the above functions is a composite spiral wound membrane, which includes parts such as a biological anode, a biological cathode, an ion - exchange membrane module, a concentrated water pipeline, a desalinated water pipeline, etc.

[0005] In addition, there are also the following technical problems that need to be solved urgently;

[0006] 1. The original spiral wound membrane monomer is equipped with independent systems such as structure, fixation, water circuit, and circuit. How to form a multi - branch arrangement during the process of scale - up and moderately combine the supporting systems therein is the main problem regarding system integration, space utilization, and economy;

[0007] 2. The membrane winding operates in a submerged state. During operation, it is necessary to operate on the membrane winding for offline maintenance under the condition of continuous production and accurately locate it to the original installation position after maintenance. This is a severe problem raised for the requirement of continuous operation during the process of system scaling up;

[0008] 3. Regarding how to fix a single membrane roll to the membrane modules arranged in the system, the fixing method should not only consider that the strength can withstand the impact force of aeration and water flow disturbance, but also be convenient for disassembly and maintenance, thus posing a problem for the maintenance convenience of a single spiral wound membrane.

[0009] Patent document CN106698679A discloses a filtering type biocathode microbial desalination cell and a sewage treatment method, which enables sewage to enter the anode chamber, degrades organic matter in the sewage under the action of anode electrogenic microorganisms to obtain anode effluent; enables the anode effluent to enter the cathode chamber, and removes suspended solids, bacteria and organic matter in the anode effluent under the combined action of cathode electrogenic microorganisms, filtration treatment and aeration treatment to obtain cathode effluent; enables the cathode effluent to enter the fresh chamber and the concentrated chamber, and removes salts in the cathode effluent under the action of an ion exchange membrane. This solution fails to solve the above technical problems. Summary of the Invention

These all belong to the protection scope of the present utility model.

[0043] Example 1:

[0044] As Figures 1 to 3 shown, this embodiment provides an array-type microbial electro-desalination device, including: a component base 1 and a plurality of array-type components 2; the array-type component 2 includes an upper fixing part 201 and a lower fixing part 202, and the upper fixing part 201 is detachably arranged on the lower fixing part 202; the upper fixing part 201 is provided with one or more roll-type membranes 3; the lower fixing part 202 is arranged on the component base 1, and the upper fixing parts 201 of two adjacent array-type components 2 are detachably connected. The overall shape of a single array-type component 2 is a T-shaped structure.

[0045] In this embodiment, a plurality of array-type components 2 are arranged at intervals on the component base 1, and the array-type components 2 are arranged parallel to each other.

[0046] In a single array component 2, the spacing between adjacent spiral membranes 3 is 2 - 5 cm. Adjacent two array components 2 are connected by a fixing device 4; the fixing device 4 is any one of the following: a union structure, a flange structure, a threaded structure, a copy lens structure.

[0047] The upper fixing part 201 and the lower fixing part 202 are detachably connected through a coupling system 5. The coupling system 5 is any one of the following: a socket structure, a slide rail structure, a mortise and tenon structure. The coupling system 5 includes a first connecting pipe 501 and a second connecting pipe 502; the first connecting pipe 501 and the second connecting pipe 502 are sleeved and connected; the first connecting pipe 501 is connected to the upper fixing part 201, and the second connecting pipe 502 is connected to the lower fixing part 202. The functions of directional extraction and precise return are realized through the coupling system 5. In other embodiments, the coupling system 5 can be other structures that can achieve the same functions.

[0048] The upper fixing part 201 includes two T-shaped structures 2011 and a connecting and fixing rod 2012; the two T-shaped structures are connected and fixed by the connecting and fixing rod 2012; the T-shaped structures 2011 of adjacent two array components 2 are detachably connected. A roll fixing device 7 is arranged on the array component 2, and the roll fixing device 7 is used for fixing the spiral membrane 3. The roll fixing device 7 is an O-shaped buckle. In other embodiments, the roll fixing device 7 can be other structures that can achieve the same functions.

[0049] In this embodiment, the two T-shaped structures 2011 are arranged relatively parallel, there are two connecting and fixing rods 2012, the two ends of the connecting and fixing rod 2012 are perpendicular to the cross bar parts of the two T-shaped structures 2011 respectively, the two ends of one connecting and fixing rod 2012 are respectively connected to the cross bar parts of the two T-shaped structures 2011, and the two ends of the other connecting and fixing rod 2012 are respectively connected to the vertical rod parts of the two T-shaped structures 2011. The lower fixing part 202 is a frame structure composed of two vertical rods and a connecting plate, the two vertical rods are arranged relatively parallel on the component base 1, and the two ends of the connecting plate are respectively connected to the two vertical rods.

The spiral membrane 3 is fixed by the roll fixing device 7 and immersed under the liquid level, increasing the contact area with the liquid and improving the working efficiency.

[0052] During maintenance inspection, since the T-shaped structure 2011 adjacent to the upper fixing part 201 of the array component 2 is detachably connected, multiple array components 2 can be separated. Just loosen the fixing device 4 provided at the two transverse ends of the T-shaped structure 2011, and multiple array components 2 can be separated into individual array components 2. Further, by separating the first connection pipe 501 and the second connection pipe 502 of the separation coupling system 5, separating the upper fixing part 201 connected to the first connection pipe 501 and the lower fixing part 202 connected to the second connection pipe 502, the disassembly, inspection or replacement of an individual array component 2 can be achieved, thereby ensuring that the remaining part can continue to work.

[0053] In other words, only need to loosen the fixing device 4 of the array to be operated, and then lift the first connection pipe 501 of the coupling system 5 of the array to be operated upward along its coupling and fixing direction, so that it can be decoupled from the corresponding second connection pipe 502 to complete the decoupling operation; after maintenance, align the first connection pipe 501 of the coupling system 5 with the corresponding second connection pipe 502 and slide it downward to complete the positioning and fixing operations.

[0054] Specifically, as Figure 1 shown, the A direction is the decoupling and lifting direction, that is, upward; the B direction is the coupling and fixing direction, that is, downward; the C direction is the array adjacent position connection direction, that is, the pointing direction of the transverse rod of the T-shaped structure 2011.

[0055] Example 2:

[0056] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0057] This embodiment provides an integration method for a vertical roll membrane system, which solves a series of problems such as space intensification, off-line maintenance and fixing of an immersed membrane roll.

[0058] An array-type microbial electro-desalination device for a roll membrane group provided in this embodiment includes: a component base 1, an array component 2, a roll membrane 3, a fixing device 4, a coupling system 5, a pipeline system 6, and a membrane roll fixing device 7;

[0059] The component base 1 is an integral structure for supporting the overall system. The array component 2 is quickly installed and disassembled through the coupling system 5.

[0060] The structural form of the array component 2 is selected from profiles such as round tubes, square steels, angle steels, I-beams, and channel steels; the materials are engineering materials with mechanical strength and anti-corrosion properties such as stainless steel, carbon steel anti-corrosion, UPVC, ABS, PP, and PE.

[0061] The fixing device 4 is arranged on the upper fixing part 201 of the array component 2; the connection between arrays is realized by the fixing device 4 arranged at the lateral end of the T-shaped structure 2011 of the upper fixing part 201, and the connection method is achieved through forms such as flexible joints, copy forest joints, flanges, screw threads, etc.

[0062] The coupling system 5 is arranged on two main components, namely the component base 1 and the array component 2, and they are in one-to-one correspondence, so as to complete the coupling and decoupling work; the coupling system 5 is fixed, positioned and slid by forms such as socket and spigot, slide rail, mortise and tenon, etc.

[0063] In other words, the coupling system 5 is divided into a first connecting pipe 501 and a second connecting pipe 502; the component base 1 is placed at the bottom end of the second connecting pipe 502; the top end of the first connecting pipe 501 is installed with the array component 2; the other end of the bottom end of the second connecting pipe 502 and the other end of the top end of the first connecting pipe 501 are coupled and connected; between the arrays of the array component 2, they are connected by the fixing device 4.

[0064] The membrane roll fixing device 7 is arranged at the main body part of the array component 2 and is used to fix the roll-type membrane 3, which corresponds to the roll-type membrane 3 according to the membrane roll length, or multiple membrane roll fixing devices 7 correspond to one roll-type membrane.

[0065] The overall system will be configured with multiple roll-type membrane components. To ensure the intensive layout of the space between the roll-type membranes 3, at the same time, the supporting water distribution system, pipelines, circuits, etc. will be integrated. The overall layout form adopts a vertical membrane component and the membrane roll spacing is controlled between 2 and 5 cm. Among them, the roll-type membrane 3 is immersed under the liquid level. To ensure off-line operation during maintenance, a form of upper and lower two sets of membrane group frames is adopted.

[0066] To ensure that the membrane roll system can be operated off-line during maintenance and inspection, an array component form is adopted, and multiple roll-type membranes 3 can be installed in one set of array. The array is positioned and connected to the bottom bracket through a coupling and fixing method, and the arrays are fixedly connected to each other through the fixing device 4 arranged at the upper end of the array bracket, that is, the T-shaped structure 2011 of the upper fixing part 201.

[0067] When off-line maintenance of the roll-type membrane 3 is required, only need to loosen the fixing device 4 for array connection of the array to be operated, and then lift the array to be operated upward along the coupling and fixing direction to complete the decoupling operation; after the maintenance is completed, align the coupling system 5 of the array component with the coupling system 5 of the component base 1 and slide downward, then the positioning and fixing operation can be completed.

[0068] Example 3:

[0069] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1 and Embodiment 2.

[0070] In a 50m 3 / d scale urban sewage treatment device, 90 spiral wound membranes 3 are arranged in-situ to complete the target ion concentration process. By adopting the layout form of this array component 2, a total of 9 arrays are set, and each array is set with a combination of 10 spiral wound membranes 3, and the embedded layout design is completed in a reaction zone of 2×2m.

[0071] A single group of the array component 2 adopts a T-shaped structure 2011, and the main structure is made of a circular pipe. A pair of T-shaped structures 2011, four ends, are provided with quick couplings for connection; the coupling system 5 of the base adopts a circular pipe one size larger than the T-shaped array book component to form the coupling system 5. That is, the fixing and separation of multiple rows of array components 2 are realized through quick couplings, and the overall lifting decoupling and rapid and accurate positioning during installation are realized through the coupling action of the circular pipe between the array component 2 and the base.

[0072] The 10 spiral wound membrane modules in a single series are fixed in the array component through O-shaped buckles, forming an integral body with the array component, and are lifted out as a whole during installation and offline maintenance, and maintenance and other operations are carried out on each membrane component outside the system.

[0073] In this embodiment, a horizontal support plate 8 is additionally arranged between the second connecting pipes 502 of the array component 2, and its function is to assist in supporting the weight of the spiral wound membrane 3, share the burden of the O-shaped buckle, and strengthen the overall strength of the array component 2. Further, the horizontal support plate 8 can slide and adjust its position on the second connecting pipe 502 and be fixed, so as to be suitable for supporting spiral wound membranes 3 of different lengths.

[0074] Around the structural support of the array component 2, the water circuit, circuit and other components supporting the system are integrated, and the whole system is fixed together, that is, the miscellaneous pipelines are sorted out to reduce the space requirement, and it is also convenient for operation and maintenance in units of arrays.

[0075] Achieved effects: Compared with the original single membrane roll independent fixing scheme, the supporting support materials and labor costs of this set of devices are saved by 30%. The array layout is convenient for installation, and only 2 hours are required to complete the main layout work. During the operation of the device, the decoupling and restoration processes of the array component 2 are practiced, and only 10 minutes are required for a single group operation, which greatly saves the operation time.

[0076] Compared with the form of conventional single spiral wound membrane 3 independent layout, that is, the form of an independent system with its own support, fixing, and lifting system, etc., the floor area can be saved by about 50%.

[0077] The utility model fixes the adjacent components by means of detachable connection through the arrangement of array components, which can not only form an intensive roll film arrangement but also fix the whole, greatly saving the material consumption, floor area and space. Moreover, when maintaining offline, the roll film can be detached independently, balancing the convenience of offline operation of a single film roll and the requirement of intensive spatial arrangement of array components.
