Description

Technical Field

[0001] The present invention relates to the technical field of wastewater ion exchange equipment, and particularly to an industrial wastewater discharge treatment device and method. Background Art

[0002] In the work of industrial wastewater discharge treatment, the basic principle of the wastewater ion exchange treatment method is to exchange ions in the wastewater with the exchange ions in the ion exchanger, use resin particles as carriers, and regularly supplement the ion exchange liquid to the resin particles, so as to remove harmful ions in the wastewater. The driving force of the exchange process mainly comes from the concentration difference between ions and the affinity of functional groups on the exchanger for ions. There are various types of wastewater discharge treatment devices. Among them, the hybrid ion exchanger is characterized in that its positive and negative ion exchange resins can simultaneously carry out positive and negative ion exchange work in the tank, and has advantages such as high efficiency. However, when the positive and negative ions of the current industrial wastewater discharge treatment device are replenishing liquid, it mainly relies on the density difference between the positive and negative ion resin particles, and uses the static method to stratify the positive and negative particles. The subsequent replenishing liquid work has poor accuracy, it is difficult to ensure that the positive and negative resin particles are accurately distinguished, it is not convenient for stratified sealing replenishment of liquid, and it is also not convenient to automatically switch the resin ions that have reached the service life, relying on manual observation, which affects the wastewater treatment effect. At the same time, manual operations such as backwashing are cumbersome and inefficient, and it is not convenient to replenish the ion exchange liquid without stopping the machine.

[0041] In the embodiment of the present disclosure, the water collection part 1 further includes: a liquid inlet cover plate 102 and a liquid discharge isolation cylinder 103. The liquid inlet cover plate 102 is installed on the top of the water collection tank 101 through bolts; a water inlet pipe for inlet of waste water is provided on the liquid inlet cover plate 102; the liquid discharge isolation cylinder 103 is fixedly installed inside the water collection tank 101; a drainage hose is externally connected to the liquid discharge isolation cylinder 103; the switching part 2 includes: a switching motor 201, a switching block 202 and a rotating liquid replenishing hole 2021. The switching motor 201 is fixedly installed on the water collection tank 101; the output shaft of the switching motor 201 passes through the water collection tank 101; a switching block 202 is fixedly installed on the output shaft of the switching motor 201; three threaded holes are provided on the switching block 202; the switching block 202 is rotatably sleeved inside the water collection tank 101; three rows of rotating liquid replenishing holes 2021 are provided on the switching block 202; the three rows of rotating liquid replenishing holes 2021 are respectively aligned with a row of fixed liquid replenishing holes 1012; the top of the switching block 202 is attached to the liquid discharge isolation cylinder 103. By adopting the switching part 2, it can cooperate with the water collection part 1 to realize the rotation and replacement of the ion exchange part 3, which can increase the flexibility of the water treatment structure of this structure, avoid the suspension of waste water treatment caused by the incapability of the single ion exchange part 3 to continue treating waste water after the capacity is reduced. The control of this structure is simple. After the water is inlet through the liquid inlet cover plate 102 in this structure and drained from the liquid discharge isolation cylinder 103, the waste water after ion exchange can be fully utilized to clean the ion exchange part 3 with reduced capacity, which is convenient for subsequent liquid replenishment. This structure can utilize the three ion exchange parts 3 in a cyclic manner to ensure the service life of this structure, can be electrically controlled for switching to ensure the continuity of waste water treatment, and reduce the pollution of industrial waste water.

[0042] In the embodiments of the present disclosure, the ion exchange unit 3 includes: an exchange installation cylinder 301, a liquid passing port 3011, and a fixed isolation net 302. The exchange installation cylinder 301 is sleeved inside the switching block 202; the bottom of the exchange installation cylinder 301 is threadedly connected to a threaded hole on the switching block 202; ten rows of liquid passing ports 3011 are provided on the exchange installation cylinder 301, and the heights of the ten rows of liquid passing ports 3011 respectively correspond to the rotary liquid supplement holes 2021; a row of fixed isolation nets 302 is fixedly installed inside the exchange installation cylinder 301, and a row of fixed isolation nets 302 are respectively located at the intervals of a row of fixed liquid supplement holes 1012; positive and negative ion exchange resins are filled in the intervals between a row of fixed isolation nets 302. The adopted ion exchange unit 3 can utilize the intervals formed between a row of fixed isolation nets 302 to isolate the positive and negative ion exchange resins, avoiding the mixing of ion exchange resins. Compared with the traditional mixed ion exchanger, this structure does not require static mixing of ion exchange resins, nor does it need to add devices such as air jet pumps to keep the positive and negative ion exchange resins evenly mixed. By filling the positive and negative ion exchange resins in the intervals between a row of fixed isolation nets 302, it ensures that the wastewater is sequentially treated by the positive and negative ion exchange resins, which can guarantee the treatment quality. At the same time, the adopted exchange installation cylinder 301 is flexible to disassemble, ensuring practicality. After removing the bolts between the liquid inlet cover plate 102 and the water collection tank 101, the exchange installation cylinder 301 at the liquid discharge isolation cylinder 103 can be rotated and disassembled. The water inlet pipe on the liquid inlet cover plate 102 is docked with the water inlet of the wastewater pump. After the wastewater undergoes ion exchange through the positive and negative ion exchange resins in the two lower exchange installation cylinders 301, under the action of water pressure, the treated industrial wastewater is discharged from the exchange installation cylinder 301 located at the liquid discharge isolation cylinder 103 and discharged through the drainage hose on the side of the liquid discharge isolation cylinder 103. During the process, the positive and negative ion exchange resins inside the exchange installation cylinder 301 located at the liquid discharge isolation cylinder 103 will be washed with water, which is convenient for subsequent replenishment of the ion exchange liquid.

[0043] In the embodiments of the present disclosure, the positive and negative ion replenishing member 4 includes a replenishing cover 401 and a replenishing pipe 402. There are two rows of replenishing covers 401, and the two replenishing covers 401 are respectively fixedly installed on the side of the water collecting tank 101; the two rows of replenishing covers 401 respectively cover the outside of a row of fixed replenishing holes 1012; the two rows of replenishing covers 401 are arranged at intervals and crosswise; replenishing pipes 402 are respectively fixedly installed on the two rows of replenishing covers 401, and valves are respectively provided on the two rows of replenishing pipes 402; the two replenishing pipes 402 are respectively externally connected to positive and negative ion replenishing pumps; the replenishing isolation member 5 includes a shunt pipe 501, a sealing plate 502, a sliding block 5021, a tension spring 503, a shunt cavity 504 and a magnetic iron ring 505. The shunt pipe 501 is slidably sleeved on a row of fixed isolation meshes 302; a row of sealing plates 502 are fixedly installed on the shunt pipe 501, and the row of sealing plates 502 are respectively of a mesh structure; the meshes on the row of sealing plates 502 are respectively arranged in a staggered manner with the meshes on the row of fixed isolation meshes 302; a circle of sliding blocks 5021 are respectively fixedly installed on the row of sealing plates 502, and the circle of sliding blocks 5021 are respectively slidably installed inside the exchange installation cylinder 301; a tension spring 503 is sleeved on the shunt pipe 501; one end of the tension spring 503 is connected to the bottom of the fixed isolation mesh 302 at the bottom; the other end of the tension spring 503 is connected to the shunt pipe 501; a shunt cavity 504 is provided at the bottom of the shunt pipe 501, and the inner diameter of the shunt cavity 504 is larger than the inner diameter of the shunt pipe 501; the magnetic iron ring 505 is fixedly installed at the bottom of the shunt pipe 501; the positive and negative ion exchange resin is located between the lower part of the fixed isolation mesh 302 and the upper part of the sealing plate 502. Using the positive and negative ion replenishing member 4 can facilitate the staff to respectively replenish the positive ion exchange resin and the negative ion exchange resin, ensuring the sustainable use of the ion exchange resin. The cavity formed by the fixed replenishing hole 1012, the rotating replenishing hole 2021 and the liquid passing port 3011 can be used for rapid replenishment work. At the same time, this structure can use the liftable sealing plate 502 to realize the lifting and closing of the fixed isolation mesh 302, which can prevent the fixed isolation mesh 302 from causing the mixing of positive and negative ion exchange liquids, affecting the water treatment effect of the ion exchange resin, keeping the exchange liquids inside the positive ion exchange resin and the negative ion exchange resin working independently, ensuring that the positive ion exchange resin and the negative ion exchange resin always only absorb the positive ion exchange liquid and the negative ion exchange liquid, with simple control, avoiding the situation that when the positive and negative ion exchange liquids of the traditional mixed ion exchanger are replenished, the replenishing nozzles are mostly set between the positive and negative ion exchange resins. During actual replenishment, the stratification between the positive and negative ion exchange resins is not absolutely horizontal, and the positive and negative ion exchange resins at the stratification are prone to mixing, resulting in the situation that the positive ion exchange resin absorbs the negative ion exchange liquid or the negative ion exchange resin absorbs the positive ion exchange liquid.

[0044] In the embodiments of the present disclosure, the magnetic attraction control member 6 includes: a magnetic attraction seat 601, a liquid passing column 602, an electromagnet 603, and a plugging head 604.

The magnetic attraction control member 6 adopted can be used to control the sealing plate 502 to fit the fixed isolation net 302 with misaligned mesh holes for closing, and at the same time, it can drive the shunt cavity 504 to move downwards to align with the plugging head 604, realize the control of conducting the shunt pipe 501, and carry out temporary drainage work, ensuring that after the fixed isolation net 302 is closed and isolated, the wastewater after ion exchange can be discharged through the shunt pipe 501, ensuring the continuity of wastewater treatment, avoiding the problem of abnormal drainage when replenishing the positive and negative ion exchange resins, ensuring that this structure can realize the replenishment of the positive and negative ion exchange resins without stopping the machine, and the structure is more reasonable. The control of this structure is simple. When the electromagnet 603 magnetically attracts the magnetic attraction iron ring 505 above, the shunt pipe 501 moves downwards, driving the shunt cavity 504 to move downwards. The inner diameter of the shunt cavity 504 is larger than the inner diameter of the shunt pipe 501. At this time, the diameter of the plugging head 604 cannot close the shunt cavity 504, and at this time, the treated wastewater can be discharged from the top of the shunt pipe 501.

[0045] Embodiment 2. On the basis of Embodiment 1, the resin life test piece 7 includes: a fixed cylinder frame 701, a lifting column 702, and a filter block 703. The filter block 703 is provided with mesh holes; the fixed cylinder frame 701 is fixedly installed inside the shunt pipe 501; a circle of through holes is provided on the fixed cylinder frame 701; the lifting column 702 is slidably installed on the fixed cylinder frame 701; the plugging head 604 corresponds to the lifting column 702; the filter block 703 is fixedly installed on the lifting column 702; the filter block 703 is sleeved inside the fixed cylinder frame 701; the filter block 703 is used for filtering impurities; the resin life test piece 7 further includes: a pressure sensor 704, a matching spring 705, and a sliding disk 706. The HZC-H1 type pressure sensor 704 can be used and a supporting display is adopted. The pressure sensor 704 is fixedly installed inside the fixed cylinder frame 701; the pressure sensor 704 is externally connected to a display; the matching spring 705 is located inside the fixed cylinder frame 701; the sliding disk 706 is slidably installed inside the fixed cylinder frame 701; the sliding disk 706 is attached to the end of the pressure sensor 704; the matching spring 705 is connected between the sliding disk 706 and the lifting column 702. The resin life test piece 7 can be used to detect the service life of positive and negative ion exchange resins, avoid the situation that the positive and negative ion exchange resins are not found when they are broken, ensure the wastewater treatment quality of this structure. At the same time, this structure can comprehensively detect impurities for the three ion exchange parts 3, ensuring the comprehensiveness of the resin life detection of this structure. The quality of the wastewater can be detected through the filter block 703 to prevent the situation that too many impurities in the wastewater inlet are not found. During actual detection, when the shunt pipe 501 moves downward, it can drive the lifting column 702 to move downward. If there is a problem of fragmentation of the positive and negative ion exchange resins, the fragmented positive and negative ion exchange resins will leak from the mesh holes on the sealing plate 502. When the sealing plate 502 moves downward, it will be blocked by the fragmented resin impurities and will not fit completely with the fixed isolation net 302. The elastic force value of the corresponding matching spring 705 will change and can be detected through the pressure sensor 704. If the impurity content of the wastewater is too high, at this time the filter block 703 will be blocked. Then under the action of water pressure, the matching spring 705 will be compressed by the water pressure and the elastic force will increase, and can be detected through the pressure sensor 704.

[0046] An industrial wastewater discharge treatment method:

[0047] 1). The water inlet pipe on the liquid inlet cover plate 102 is docked with the water inlet of the wastewater pump. After the wastewater undergoes ion exchange through the positive and negative ion exchange resins in the two lower exchange installation cylinders 301, under the action of water pressure, the treated industrial wastewater is discharged from the hose on the side of the exchange installation cylinder 301 below the liquid discharge isolation cylinder 103.

[0048] 2) Start the switching motor 201 to drive the switching block 202 to drive the exchange installation cylinder 301 to rotate, switch and align the exchange installation cylinder 301 of the positive and negative ion replenishing member 4, and supplement the positive and negative ion replenishing liquid to the positive and negative ion exchange resin in the exchange installation cylinder 301 through the positive and negative ion replenishing member 4.

After the waste water undergoes ion exchange through the positive and negative ion exchange resin in the two lower exchange installation cylinders 301, under the action of water pressure, the treated industrial waste water is discharged from the exchange installation cylinder 301 located below the liquid discharge isolation cylinder 103 and discharged through the drainage hose on the side of the liquid discharge isolation cylinder 103. During this process, the positive and negative ion exchange resin inside the exchange installation cylinder 301 located at the liquid discharge isolation cylinder 103 will be washed by water, which is convenient for subsequent replenishment of the ion exchange liquid. After the capacity of the positive and negative ion exchange resin in the two exchange installation cylinders 301 at the water inlet end decreases, the switching motor 201 can be started to drive the switching block 202 to drive the exchange installation cylinder 301 to rotate and switch to below the liquid discharge isolation cylinder 103, which is convenient for cleaning and subsequent replenishment work. In this way, the waste liquid treatment and the replenishment work after the positive and negative ion exchange resin is washed by water are continuously carried out; by magnetically attracting the magnetic iron ring 505 above by the electromagnet 603, the flow dividing pipe 501 is controlled to move downward, so as to drive the sealing plate 502 to fit the fixed isolation net 302 with misaligned mesh holes for sealing, avoiding the mixing of positive and negative replenishing liquids. The positive and negative ion replenishing pumps connected to the two replenishing pipes 402 are respectively started to pump an appropriate amount of replenishing liquid between a row of fixed isolation nets 302; when the electromagnet 603 magnetically attracts the magnetic iron ring 505 above, the flow dividing pipe 501 moves downward, driving the flow dividing cavity 504 to move downward. At this time, the flow dividing cavity 504 is sleeved on the plugging head 604, and the plugging head 604 no longer seals and fits the magnetic iron ring 505 for sealing. Because the inner diameter of the flow dividing cavity 504 is larger than the inner diameter of the flow dividing pipe 501, the diameter of the plugging head 604 cannot seal the flow dividing cavity 504 at this time. At this time, the treated waste water can flow into the flow dividing cavity 504 from the through holes on the circumferential surface of the liquid passing column 602, be discharged from the top of the flow dividing pipe 501 and then discharged through the drainage hose on the side of the liquid discharge isolation cylinder 103. The two shielding plates 1011 can shield the top end of the lower flow dividing pipe 501 in real time for sealing to prevent leakage;

[0050] If the positive and negative ion exchange resins are fractured, the fractured positive and negative ion exchange resins will leak through the mesh holes on the sealing plate 502. At this time, resin impurities will remain between the upper part of the fixed isolation net 302 and the sealing plate 502. When the sealing plate 502 moves downward, it will not completely fit the fixed isolation net 302. The downward movement distance of the corresponding lifting column 702 will be shortened. The lifting column 702 moves downward and touches the plugging head 604. However, the downward pressing stroke of the lifting column 702 is short, the compression amount of the matching spring 705 is reduced, and the elastic force value of the corresponding matching spring 705 will change, which can be detected by the pressure sensor 704. If the reading of the pressure sensor 704 is smaller than the normal value, it means that there are resin impurities between the upper part of the positive fixed isolation net 302 and the sealing plate 502. At the same time, the filter block 703 can be used to filter impurities. If the impurity content of the wastewater is too high, there are mesh holes on the filter block 703. At this time, the mesh holes of the filter block 703 will be partially blocked. Then, under the action of water pressure, the filter block 703 will drive the lifting column 702 to rise under the action of water pressure, compress the matching spring 705, and the matching spring 705 will be compressed by the water pressure, and the elastic force increases, which can be detected by the pressure sensor 704. The value can be displayed in real time through the display connected to the pressure sensor 704, and the water quality of the influent can be controlled in time and the filter block 703 can be cleaned.
