Description

Technical Field

[0001] This invention relates to the field of wastewater recycling technology, and in particular to a multi-media filter for wastewater recycling electrolysis and its usage method. Background Technology

[0002] Chinese Patent Application No. 201210339146X discloses a multi-media filter with a partition. The filter housing is equipped with a manhole, an exhaust valve, a water outlet, and a backwash drain. A water distributor is installed inside the filter housing. An internal partition is installed inside the filter housing, dividing the internal cavity of the filter into four small units. Each small unit contains an anthracite filter media layer and an activated carbon filter media layer. A quartz sand filter media layer is located below the activated carbon filter media layer. The bottom of the quartz sand filter media layer is a partition screen plate with a water guide cap. Its advantages are that it can avoid uneven rinsing of filter media, filter media loss, and easy layer disorder during backwashing. However, the above invention cannot effectively clean the filter media of the device, resulting in a decrease in filtration efficiency after long-term use.

[0003] Chinese patent application number 2021106878611 discloses a wastewater filtration treatment device, including a support frame, a squeeze filter element, a squeeze box, a filter box, a discharge chamber, a mixing motor, and a settling box. The squeeze filter element is provided inside the support frame, and the squeeze filter element has filter holes inside. Squeeze plates are provided at both ends of the outer side of the squeeze filter element. The other side of the squeeze plate is connected to a groove provided inside the support frame. A shaft is connected to the outer side of the squeeze plate and is connected to the squeeze box through the shaft. The filter box is provided at one end of the outer side of the support frame, and the discharge chamber is provided at the other side of the squeeze filter element. However, the above device cannot perform multi-stage filtration of wastewater and has poor filtration effect.

[0004] Traditional wastewater recycling mainly uses filtration to separate impurities and organic matter from wastewater. However, filtration alone has limited effectiveness in treating wastewater, and multiple filtrations are required to ensure treatment efficiency, resulting in poor overall treatment results.

[0005] Therefore, it is necessary to invent a multi-media filter for wastewater recycling electrolysis and its usage method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-media filter for wastewater recycling electrolysis and its usage method, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-media filter for wastewater recycling electrolysis, comprising a filter assembly, an inlet assembly, an oxidant addition assembly, an electrolysis assembly, and a drainage assembly, wherein the inlet assembly, the oxidant addition assembly, the electrolysis assembly, and the drainage assembly are connected end to end in sequence, and the inlet assembly, the oxidant addition assembly, the electrolysis assembly, and the drainage assembly are all disposed inside the filter assembly;

[0008] The filter assembly includes a hexagonal fixed cover and a baffle, and the interior of the fixed cover has six cavities arranged around it.

[0009] An electric push rod is provided on the electrode plate located on one side of the baffle. The baffle is connected to the electrode plate through the electric push rod.

[0023] A method for using a multi-media filter for wastewater recycling electrolysis, characterized by comprising the following steps:

[0024] Step 1: Wastewater injection. The wastewater is guided to the inlet component through the drain pipe. At this time, the wastewater enters the filter component through the inlet component.

[0025] Step 2: Oxidant addition. Wastewater flows through the filtration component to the oxidant addition component and mixes with the oxidant.

[0026] Step 3: Electrolysis treatment. The wastewater mixed with the oxidant enters the electrolysis unit and undergoes electrolysis treatment. At this time, the oxidant and organic matter in the wastewater undergo an oxidation-reduction electrochemical reaction, causing the organic matter that is difficult to decompose in the wastewater to precipitate out.

[0027] Step 4: Filtration and discharge. The wastewater after electrolysis is filtered in the drainage component, so that the organic matter precipitated in the wastewater is filtered out. The filtered wastewater can be discharged from the device, thus realizing the electrolytic filtration treatment of wastewater.

[0028] The technical effects and advantages of this invention are as follows:

[0029] 1. This invention features a filtration assembly containing an inlet assembly, an oxidant addition assembly, an electrolysis assembly, and a drainage assembly. Wastewater flows through the inlet assembly, sequentially passing through these oxidant addition, electrolysis, and drainage assemblies. During this flow, the wastewater undergoes oxidant addition, ionization oxidation, and filtration separation, achieving powerful oxidation treatment. Since wastewater treatment occurs as it flows through the inlet assembly, the treatment efficiency is improved, and continuous wastewater treatment is possible.

[0030] 2. This invention incorporates a filtration assembly, which includes a first filter plate, a second filter plate, and a third filter plate. The first and second filter plates each contain horizontal and vertical filter strips, respectively. The first and second filter plates work together to filter flocculent matter in wastewater. The third filter plate contains a baffle plate and a guide plate. The baffle plate reduces the speed of wastewater as it passes through the electrolysis assembly, thereby improving the electrolysis effect. The first, second, and third filter plates work together to achieve multi-media, multi-stage filtration of wastewater, ensuring effective filtration.

[0031] 3. The present invention provides a filter assembly, which includes a fixed cover. The fixed cover has multiple cavities for wastewater flow inside, and the side walls of the cavities are provided with slag discharge ports. The fixed cover has an inspection port in the middle. By removing the baffle inside the slag discharge port, the waste slag filtered out in each cavity can be cleaned through the inspection port, thereby avoiding the long-term accumulation of waste slag that affects the use of the device.

[0032] 4. This invention connects two cavities containing oxidant additive components with a connecting pipe to form a communicating vessel, allowing wastewater to flow freely between the two oxidation cavities. This prevents the first filter plate on one side from clogging and causing the oxidation cavity on the other side to burst. At the same time, by setting an electric push rod on one side of the electrode plate, the electric push rod drives the electrode plate to move, causing the wastewater to flow in the opposite direction in the oxidation cavity. This effectively clears blockages in the first and second filter plates and the water passage holes, improving the filtration effect of the device on wastewater and preventing clogging problems during use.

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] This invention provides, for example Figures 1 to 14 The multi-media filter for wastewater recycling electrolysis shown includes a filter assembly 1, an inlet assembly 2, an oxidant addition assembly 3, an electrolysis assembly 4, and a drainage assembly 5. The inlet assembly 2, the oxidant addition assembly 3, the electrolysis assembly 4, and the drainage assembly 5 are connected end to end in sequence, and the inlet assembly 2, the oxidant addition assembly 3, the electrolysis assembly 4, and the drainage assembly 5 are all disposed inside the filter assembly 1.

[0051] The filter assembly 1 includes a hexagonal fixed cover 101, and the interior of the fixed cover 101 is provided with six cavities 102.

[0052] Specifically, the interior of the fixed cover 101 is provided with two sets of symmetrically distributed first filter plates 103, second filter plates 104 and third filter plates 105, which are sequentially disposed through the middle of the inner sidewall of multiple cavities 102.

[0053] More specifically, the first filter plate 103 is provided with multiple vertical filter bars 106 with a wave-like structure inside, the second filter plate 104 is provided with multiple horizontal filter bars 107 with a wave-like structure inside, and the bottom of the third filter plate 105 is fixedly provided with multiple inclined baffles 108 and guide plates 109. The guide plates 109 are fixedly provided at the top of the baffles 108, and the inclination angle of the guide plates 109 is smaller than that of the baffles 108. When the wastewater passes through the baffles 108, the wastewater will hit the surface of the baffles 108 to reduce the flow speed of the wastewater, thereby prolonging the residence time of the wastewater in the electrolysis component 4. When the wastewater volume is large, the wastewater at the top can directly pass through the guide plates 109 and be discharged, thereby avoiding the accumulation of wastewater in the electrolysis component 4 and the backflow.

[0054] Furthermore, handles 110 are fixedly provided in the middle of the upper surface of the first filter plate 103, the second filter plate 104 and the third filter plate 105, and mounting bases 111 are fixedly provided at both ends of the upper surface of the first filter plate 103, the second filter plate 104 and the third filter plate 105, and the mounting bases 111 are fixedly provided on the upper surface of the fixing cover 101 by bolts.

[0055] Furthermore, an inspection port 112 is provided in the middle of the upper surface of the fixed cover 101. A screw sleeve 113 is fixedly installed in the middle of the bottom end of the inspection port 112. Multiple slag discharge ports 114 are provided around the top of the inner side wall of the inspection port 112. Sealing grooves 115 are provided on both sides of the inner wall of the slag discharge port 114. A baffle 116 is provided inside the slag discharge port 114. When the baffle 116 is removed, the waste residue in each cavity 102 can be cleaned through the slag discharge port 114.

[0056] Furthermore, sealing blocks 117 adapted to the sealing groove 115 are fixedly installed on both sides of the baffle 116. The sealing blocks 117 and the sealing groove 115 cooperate to ensure the sealing effect between the baffle 116 and the inner wall of the cavity 102. A fixing frame 118 is fixedly installed between multiple baffles 116. A locking bolt 119 is provided at the middle of the bottom end of the fixing frame 118, and the bottom end of the locking bolt 119 is located inside the threaded sleeve 113. The locking bolt 119 cooperates with the threaded sleeve 113 to fix the position of the fixing frame 118, thereby fixing the position of the baffle 116.

[0057] The water inlet assembly 2 includes a first guide plate 201, the oxidant addition assembly 3 includes a second guide plate 301, the electrolysis assembly 4 includes a third guide plate 401, and the drainage assembly 5 includes a fourth guide plate 501. The first guide plate 201, the second guide plate 301, the third guide plate 401, and the fourth guide plate 501 are respectively disposed in the cavity 102 inside the fixing cover 101, and the heights of the first guide plate 201, the second guide plate 301, the third guide plate 401, and the fourth guide plate 501 decrease sequentially. Because the first guide plate... The heights of the first guide plate 201, the second guide plate 301, the third guide plate 401, and the fourth guide plate 501 decrease sequentially, so the wastewater can flow through the first guide plate 201, the second guide plate 301, the third guide plate 401, and the fourth guide plate 501 in sequence. The wastewater flows through the inlet component 2, the oxidant addition component 3, the electrolysis component 4, and the drainage component 5 in sequence. During this process, flocculent filtration, oxidant addition, electrolysis treatment, and re-filtration are completed. After the re-filtration is completed, the wastewater is discharged from the device through the water guide pipe 508.

[0058] Specifically, a guide block 202 with a boss structure is fixedly installed in the middle of the upper surface of the first guide plate 201. After the wastewater enters the water inlet component 2, the wastewater falls above the guide block 202 and flows to both sides along the inclined surfaces on both sides of the guide block 202. The wastewater enters the two oxidant addition components 3 respectively.

[0059] More specifically, water guide pipes 508 are provided above the first guide plate 201 and below the fourth guide plate 501, and the water guide pipes 508 can be connected to the wastewater discharge pipes.

[0060] An installation plate 302 is provided above the second guide plate 301. Multiple installation sleeves 303 are provided through the middle of the installation plate 302. A discharge cover 304 is fixedly provided at the bottom of the installation sleeve 303. Multiple water passage holes 305 are provided around the outer wall of the discharge cover 304. Wastewater passes through the water passage holes 305 and enters the discharge cover 304 and mixes with the oxidant in the discharge cover 304, so that the oxidant dissolves in the wastewater.

[0061] Specifically, a spiral-structured feeding guide plate 306 is fixedly installed inside the feeding hood 304. The spiral structure of the feeding guide plate 306 can guide the falling of the oxidant to avoid a large amount of oxidant falling at the same time. A storage hood 307 is fixedly installed at the top of the mounting sleeve 303, which can store the oxidant.

[0062] A support plate 402 is provided above the third guide plate 401. Two parallel slots 403 are opened through the upper surface of the support plate 402. Insert plates 404 are inserted into the slots 403. Both ends of the insert plates 404 are set with inclined structures. The inclined structures can guide the wastewater to ensure that the wastewater passes between the two electrode plates 405.

[0063] Specifically, electrode plates 405 are provided on the side of the two insert plates 404 that are close to each other. When the two electrode plates 405 are energized, they can generate an electric field. The organic matter that is difficult to degrade in the wastewater can undergo an electrolytic oxidation-reduction reaction with the oxidant in the electric field, causing the organic matter that is difficult to degrade in the wastewater to precipitate out.

[0064] More specifically, two sets of symmetrically arranged water-blocking plates 406 are fixedly installed on the lower surface of the support plate 402, and the two adjacent water-blocking plates 406 are staggered. The water-blocking plates 406 can block the flow trajectory of wastewater, thereby extending the time for wastewater to pass between the two electrode plates 405, thus improving the electrolytic treatment effect of wastewater.

[0065] Furthermore, a drainage groove 502 is provided through the middle of the fourth guide plate 501. A fixed frame 503 is fixedly installed at the opening of the drainage groove 502. A movable frame 504 is provided above the fixed frame 503. A screen 505 is provided through the outer wall of the movable frame 504. An insert frame 506 adapted to the fixed frame 503 is fixedly installed at the bottom of the movable frame 504. A pressure plate 507 is provided at the top of the movable frame 504. The pressure plate 507 is fixedly installed above the fourth guide plate 501 by bolts. The pressure plate 507 can fix the position of the movable frame 504.

[0066] This invention also provides a method for using a multi-media filter for wastewater recycling electrolysis, comprising the following steps:

[0067] Step 1: Wastewater injection. The wastewater is guided to the inlet component 2 through the drain pipe. At this time, the wastewater enters the filter component 1 through the inlet component 2.

[0068] After entering the inlet component 2, the wastewater falls above the guide block 202 and flows to both sides along the inclined surfaces on both sides of the guide block 202. The wastewater enters the two oxidant addition components 3 respectively. At this time, the wastewater passes through the first filter plate 103, and some of the flocculent matter in the wastewater is filtered by the first filter plate 103.

[0069] Step 2: Oxidant addition. Wastewater flows through filter component 1 to oxidant addition component 3 and is mixed with the oxidant.

[0070] After entering the oxidant addition component 3, the wastewater passes through the water passage 305 into the discharge hood 304 and mixes with the oxidant in the discharge hood 304, causing the oxidant to dissolve in the wastewater. At this time, the oxidant in the storage hood 307 above the discharge hood 304 falls into the discharge hood 304 under the action of gravity, so as to ensure that the subsequent wastewater can be added with oxidant. The wastewater mixed with the oxidant continues to move through the second filter plate 104 and enters the electrolysis component 4. At this time, another part of the flocculent matter in the wastewater is filtered by the second filter plate 104.

[0071] Step 3: Electrolysis treatment. The wastewater mixed with the oxidant enters the electrolysis unit 4 and undergoes electrolysis treatment in the electrolysis unit 4. At this time, the oxidant and organic matter in the wastewater undergo an oxidation-reduction electrochemical reaction, causing the organic matter that is difficult to decompose in the wastewater to precipitate out.

[0072] After entering the electrolysis unit 4, the wastewater is guided by the inclined structure at both ends of the insert plate 404 and enters between the two electrode plates 405. Since the two electrode plates 405 are energized, an electric field is generated. Therefore, the organic matter that is difficult to degrade in the wastewater and the oxidant can undergo an electrolytic oxidation-reduction reaction in the electric field, causing the organic matter that is difficult to degrade in the wastewater to precipitate. At this time, the treatment of the organic matter that is difficult to degrade in the wastewater can be achieved. The electrolyzed wastewater and the precipitated organic matter continue to move into the drainage unit 5.

[0073] Step 4: Filtration and discharge. The wastewater after electrolysis is filtered in the drainage component 5, so that the organic matter precipitated in the wastewater is filtered out, and the filtered wastewater can be discharged from the device. Thus, the electrolytic filtration treatment of wastewater can be realized.

[0074] After entering the drainage component 5, the wastewater is filtered and screened by the screen 505. The precipitated organic matter is blocked by the screen 505, and the filtered wastewater can be discharged through the water guide pipe 508, thus completing the wastewater treatment.

[0075] Example 2

[0076] In actual use, operators found that when the device performs multi-stage filtration on collected wastewater, the wastewater passes through the first filter plate 103, the second filter plate 104, and the third filter plate 105 in sequence, and impurities in the wastewater are retained on one side of the first filter plate 103, the second filter plate 104, and the third filter plate 105, respectively. Because the wastewater contains a lot of impurities, after a long period of use, one side of the first filter plate 103 and the second filter plate 104 will be completely covered by impurities, causing the wastewater to be unable to continue flowing downward through the first filter plate 103 or the second filter plate 104, making subsequent filtration of the wastewater impossible. If the first filter plate 103 or the second filter plate 104 is removed and replaced at this time, the unfiltered wastewater will directly enter the next cavity 102, and the impurities in the wastewater cannot be effectively filtered and treated. Therefore, in order to solve the above technical problems, the device is improved according to the method described in this embodiment.

[0077] An electric push rod 6 is provided on the electrode plate 405 located on one side of the baffle 116. The baffle 116 is connected to the electrode plate 405 through the electric push rod 6. The two ends of the electrode plate 405 with the electric push rod 6 are slidably connected to the second filter plate 104 and the third filter plate 105 through telescopic rods, respectively. A connecting pipe is provided on the baffle 116 connected to the oxidation chamber, and the two oxidation chambers are interconnected through the connecting pipe. A flow rate sensor is provided in the connecting pipe, which is used to detect the flow rate of wastewater in the connecting pipe.

[0078] Firstly, during multi-stage filtration of wastewater, since the oxidation chamber is located between the first filter plate 103 and the second filter plate 104, when neither the first filter plate 103 nor the second filter plate 104 is blocked, the inflow and outflow of water in the oxidation chamber are roughly the same, and the wastewater volume in the oxidation chamber will remain within a stable range. At this time, the two oxidation chambers are connected by a connecting pipe, so that the two oxidation chambers and the connecting pipe together form a communicating vessel. During use, the amount of wastewater guided to the inlet component 2 by the drain pipe remains constant. However, when the two first filter plates 103 are covered with debris to different degrees, the amount of wastewater filtered by the two first filter plates 103 at the same time will differ, resulting in the amount of wastewater in one oxidation chamber being greater than that in the other oxidation chamber. By setting up the connecting pipe, the amount of wastewater in the two oxidation chambers is made consistent again, thereby improving the oxidation effect of the oxidant addition component 3 on the wastewater, and at the same time preventing the oxidation chamber from bursting due to excessive wastewater volume on one side.

[0079] Secondly, when one of the first filter plates 103 is completely blocked by debris, simply connecting the two oxidation chambers through the connecting pipe cannot effectively solve the problem of the first filter plate 103 being blocked. Meanwhile, the amount of wastewater in the unblocked oxidation chamber will gradually increase, still posing a risk of cylinder explosion. At this time, a flow rate sensor installed in the connecting pipe monitors and records the flow rate in the connecting pipe in real time. Since the two oxidation chambers are connected through the connecting pipe, the flow rate of the wastewater detected by the flow rate sensor is used to determine whether the flow rate detected by the flow rate sensor is within the preset range. In this case, it is determined that the first filter plate 103 and the second filter plate 104 located on both sides of the inlet chamber are not blocked, and the wastewater content in the oxidation chambers on both sides is not significantly different, indicating that they are in normal working condition.

[0080] If the flow rate sensor detects that the flow rate in the connecting pipe exceeds the preset range, it determines that either the first filter plate 103 or the second filter plate 104 on one side is blocked, causing a difference in the amount of wastewater in the two oxidation chambers. The wastewater in the oxidation chamber with a larger wastewater volume will be transferred to the oxidation chamber with a smaller wastewater volume through the communicating vessel. During this process, the controller controls the electric push rod 6 on the unblocked side to reciprocate in lengthening and shortening, thereby reducing the amount of wastewater flowing out of the unblocked oxidation chamber. Under the push of the electrode plate 405, the excess wastewater in the unblocked oxidation chamber is squeezed again through the connecting pipe into the blocked oxidation chamber. At this time, the amount of wastewater in the blocked oxidation chamber will instantly decrease. The flow rate increases, but since the drainage volume from the oxidation chamber through the second filter plate 104 remains constant during this process, the excess wastewater will flow back into the inlet chamber through the clogged first filter plate 103. During this process, the excess wastewater will impact the debris clogged on the first filter plate 103, causing the debris to separate from the first filter plate 103, thereby restoring the clogged first filter plate 103 to its normal working state. At the same time, the controller controls the electric push rod 6 to drive the electrode plate 405 back to its initial state, thereby completing the unclogging of the first filter plate 103 and preventing the first filter plate 103 from becoming clogged after long-term use, which would prevent subsequent filtration of wastewater.

[0081] Furthermore, if, after the above operations, the flow rate sensor still detects that the flow rate in the connecting pipe exceeds the preset value, it is determined that the difference in wastewater content between the two oxidation chambers is caused by blockage of the second filter plate 104, resulting in the outflow of water from the blocked oxidation chamber being less than the preset value. At this time, the controller controls the electric push rod 6 in the electrolysis chamber on the blocked side to move the electrode plate 405 towards the baffle 116, reducing the outflow of water from the blocked oxidation chamber and simultaneously squeezing the wastewater to force it to flow through the connecting pipe into the unblocked oxidation chamber. The controller also controls the electric push rod 6 in the electrolysis chamber on the unblocked side to move the electrode plate 405 away from the baffle 116. The electrode plate 405 on the unblocked side moves away from the baffle 116, squeezing the wastewater in the electrolysis chamber. Since the flow rate in the electrolysis chamber cannot change, the squeezed wastewater impacts the second filter plate 104 in the reverse direction, separating the debris covering one side of the oxidation chamber from the second filter plate 104. At the same time, the movement of the electrode plate 405 on the unblocked side allows the wastewater flowing back into the oxidation chamber to enter the unblocked side of the oxidation chamber through the connecting pipe. This solves the problem that the second filter plate 104 becomes clogged during use, resulting in poor filtration of wastewater and the inability to filter wastewater subsequently.

[0082] Finally, as the device is used for a long time, more and more impurities will be separated from the wastewater. At this time, the controller controls the two electric push rods 6 in the device to drive the electrode plate 405 to reciprocate continuously. This causes the wastewater entering the two oxidation chambers to continuously impact the first filter plate 103 and the second filter plate 104 in the opposite direction under the push of the electrode plate 405. This separates the impurities covering the first filter plate 103 and the second filter plate 104 from the first filter plate 103 and the second filter plate 104. At the same time, the reciprocating motion of the electrode plate 405 creates turbulence in the wastewater, thereby increasing the reaction time of the wastewater with the oxide in the oxidation chamber and further improving the oxidation effect of the wastewater. The reverse flow of wastewater can also effectively clean the water passage hole 305 on the oxidant addition component 3, preventing the water passage hole 305 from being blocked by impurities, which would prevent the wastewater from contacting and reacting with the oxide.

[0083] It should be noted that this invention connects two cavities 102 containing the oxidant addition component 3 with a connecting pipe to form a communicating vessel, allowing wastewater to flow freely between the two oxidation cavities. This prevents the first filter plate 103 on one side from becoming clogged, which could cause the oxidation cavity on the other side to burst. At the same time, by setting an electric push rod 6 on one side of the electrode plate 405, the electric push rod 6 drives the electrode plate 405 to move, causing the wastewater to flow in the opposite direction within the oxidation cavity. This effectively clears blockages in the first filter plate 103, the second filter plate 104, and the water passage 305, improving the filtration effect of the device on wastewater and preventing clogging during use.

[0084] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
