Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device and method for an ecological water supply channel. Background Technology

[0002] With the acceleration of urbanization and the rapid development of industrial and agricultural production, the pollution pressure on natural water bodies is increasing daily. Eutrophication and organic pollution of open water bodies such as rivers and lakes have become key factors restricting the sustainable development of the ecological environment. Ecological water replenishment technology, as an effective means of water environment restoration, is receiving increasing attention and application. This technology introduces purified water into polluted water bodies, which not only directly dilutes pollutant concentrations but, more importantly, enhances water flow and reoxygenation capacity, activates the water body's own microbial activity, and thus gradually restores its ecological self-purification function. In this technological system, the wastewater pretreatment stage of the replenishment channel plays a crucial role—the replenishment water source itself often carries a certain amount of suspended solids, colloidal particles, and dissolved pollutants. If it is directly replenished into the receiving water body without effective treatment, it will not only fail to achieve the expected treatment effect but may also exacerbate the water body's burden. To address this need, existing technologies, such as using screens or filters to intercept large-diameter suspended solids, combined with flocculation sedimentation, biological contact oxidation, and deep chemical purification processes, form a wastewater treatment process, providing a reliable water source guarantee for ecological restoration.

[0003] Although existing ecological water replenishment channel wastewater treatment technologies have been applied in various scenarios, firstly, in terms of the connection method of multi-stage treatment processes, current equipment mostly adopts continuous water intake or one-time discharge to transport the pre-treated wastewater to the next treatment unit. This extensive material transfer mode is prone to causing instantaneous hydraulic shock to the downstream treatment system, interfering with its relatively stable physical or biochemical reaction environment. At the same time, in terms of chemical dosing, the large influx of wastewater at one time is often accompanied by the concentrated addition of purifying agents. This not only increases the difficulty of fully mixing the agents with water, but also often results in waste of agents due to overdosing. Furthermore, the filter screen, as a component that intercepts solid impurities, is difficult to clean in a timely manner and is prone to varying degrees of clogging, affecting the stability of high-efficiency filtration.

[0004] Therefore, it is necessary to provide an ecological water supply channel for wastewater treatment equipment and methods to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an ecological water supply channel for wastewater treatment equipment and method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: an ecological water replenishment channel sewage treatment device, comprising a purification tank one, a purification tank two fixed to the top of the purification tank one, a filter tank c fixed to the top of the purification tank two, an inlet pipe extending into the filter tank c and located above the filter plate connected to the side of the filter tank c, a filter plate fixed to the inner wall of the filter tank c, a bracket fixed to the top of the filter tank c, an electric push rod fixed to the top of the bracket, a flow regulating component for separating and treating sewage provided inside the purification tank two, and a closing component and a cleaning component for sealing and cleaning the filter plate provided inside the filter tank c.

[0007] As a further embodiment of the present invention, the flow regulating component includes an internal plate fixed to the inner wall of the filter box c. The internal plate has a plurality of equally spaced flow holes a on its side. A shift plate a is movably disposed above the internal plate. The shift plate a has a plurality of flow holes b on its side. The plurality of flow holes b and the plurality of flow holes a are staggered with each other.

[0008] As a further embodiment of the present invention, a plurality of adjustment posts are fixed on the side of the adjustment plate a near the built-in plate, and the plurality of adjustment posts are arranged in a one-to-one correspondence with a plurality of flow holes a. A feed pipe b communicating with the interior of the purification box is fixed on the side of the purification box two.

[0009] As a further embodiment of the present invention, the bottom end of the insertion post is provided with a tapered surface.

[0010] As a further embodiment of the present invention, a rubber sleeve is fitted onto the side of the adjusting post, and a guide slope is provided at the bottom end of the rubber sleeve.

[0011] As a further embodiment of the present invention, the cleaning component includes a blower plate embedded in the side wall of the filter box c, the blower plate having an inner cavity, and the blower plate having blower holes communicating with the inner cavity on the side facing the inside of the filter box c, the blower holes being multiple and equidistantly distributed, and an air inlet pipe communicating with the inner cavity being fixed on the side of the blower plate.

[0012] As a further embodiment of the present invention, a discharge port is provided on the side of the filter box c opposite to the blower plate, and a guide groove is fixed at the port of the discharge port.

[0013] As a further embodiment of the present invention, the adjustment assembly includes a movable and adjustable adjustment plate b disposed below the filter plate. A rubber pad is fixedly attached to the top surface of the adjustment plate b. Flow holes c aligned with each other are provided on the sides of both the adjustment plate b and the rubber pad. The plurality of flow holes c are staggered with the filter holes on the filter plate. A connecting rod b is fixed to the side of the adjustment plate b. The connecting rod b is slidably disposed through the filter plate. The output end of the electric push rod is fixed to the top end of the connecting rod b. A connecting rod a is fixed between the adjustment plate b and the adjustment plate a.

[0014] As a further embodiment of the present invention, a support rod a and a support rod b are fixed on the side of the connecting rod b, and a baffle plate a and a b are fixed at the ends of the support rod a and the support rod b, respectively, so as to seal the discharge port and the blowing hole.

[0015] A method for treating wastewater using an ecological water supply channel includes the following steps: S1. The wastewater is initially filtered and purified by the filter plate inside the filter box c to remove larger solid impurities. After filtration and purification, the wastewater flows downward into the purification box two. At this time, the adjustment plate a is at the lowest position, and the adjustment column on the adjustment plate a is inserted into the flow hole a to close the flow hole a, thereby temporarily closing the bottom of the purification box two, so that some wastewater is temporarily stored in the purification box two. A certain amount of flocculant is added into the purification box two through the feed pipe b, thereby purifying the small amount of wastewater inside the purification box two. S2. After the secondary purification is completed, the output end of the electric push rod drives the connecting rod b to move upward, thereby driving the adjustment plate b, the connecting rod a and the adjustment plate a to move upward as a whole, so that the adjustment column moves out of the flow hole a, the flow hole a is opened, and the purified sewage in the second purification box flows into the first purification box in sequence through the flow hole b and the flow hole a. S3. The output of the drive motor drives one of the stirring shafts to rotate, and the two stirring shafts rotate in opposite directions through the cooperation of two gears. The stirring rods on the two stirring shafts thoroughly and evenly stir the sewage inside the purification tank. The purification agent liquid is delivered and added to the purification tank through the feed pipe a, so that the purification agent and sewage are thoroughly and evenly mixed, and the sewage is further purified. S4. When the electric push rod drives the connecting rod b to move upward, the connecting rod b drives the baffle a and the baffle to move upward synchronously. At this time, the blowing hole and the impurity discharge port are automatically opened. The air with a certain air pressure is delivered to the inside of the blowing plate through the air inlet pipe. The air is then blown evenly and finely onto the top surface of the filter plate through multiple blowing holes, thereby blowing away and cleaning the solid impurities filtered out of the filter plate.

[0016] S5. When cleaning the filter plate, the rubber pad on the side of the adjustment plate b is pressed tightly against the bottom surface of the filter plate, thereby sealing the filter holes on the filter plate through the adjustment plate b and the rubber pad. By sealing the filter holes of the filter plate before blowing away impurities, it is possible to prevent impurities from falling into the purification box two or purification box one through the filter holes of the filter plate during cleaning.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. Wastewater is transported into filter box C through the inlet pipe. The wastewater undergoes preliminary filtration and purification through the filter plates inside filter box C, removing larger solid impurities. After filtration and purification, the wastewater flows downward into purification box two. A flow regulating component allows some wastewater to be temporarily stored in purification box two, where a small amount of wastewater undergoes secondary purification. After secondary purification, the bottom of purification box two is opened through the flow regulating component, allowing the wastewater that has undergone secondary purification to flow downward into purification box one. The stirring component agitates the wastewater for further purification, thus forming a multi-stage purification process. This significantly reduces the burden of a single purification process, and the multi-stage step-by-step treatment avoids excessive waste of purifying agent, improves the uniformity and thoroughness of the contact and mixing between the purifying agent and wastewater, and effectively improves the quality of wastewater purification. 2. By using the set flow regulation component, the sewage is initially purified in small batches before being put into the purification tank for further purification. The small batch inflow indicates that the matching purification agent can also be added in batches, so that each batch of sewage can fully react with sufficient and fresh agent, avoiding the waste of agent and the risk of secondary pollution caused by adding too much agent at once. At the same time, it reduces the impact when the sewage flows into the purification tank, creating a relatively stable settling environment for subsequent purification, and the effluent water quality fluctuates less. 3. While the electric push rod drives the flow regulating component to open, it also drives the closing component to close the filter holes of the filter plate. The set cleaning component blows air evenly and finely onto the filter plate, thereby sweeping away the solid impurities filtered out on the filter plate. This forms an automatic cleaning of the filter plate, preventing the accumulation and clogging of impurities on the filter plate and ensuring the high filtration efficiency of the filter plate. At the same time, the impurities are swept away after the filter holes of the filter plate are closed, thus preventing impurities from falling into the purification box two or purification box one through the filter holes of the filter plate during the cleaning process, avoiding secondary pollution of the water by solid impurities.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Please see Figure 1-12This invention provides an ecological water supply channel for wastewater treatment, including a purification tank 5, a purification tank 11 fixed to the top of the purification tank 5, a filter tank c12 fixed to the top of the purification tank 11, an inlet pipe 20 extending into the filter tank c12 and located above a filter plate 19 connected to the side of the filter tank c12, a filter plate 19 fixed to the inner wall of the filter tank c12, a bracket 15 fixed to the top of the filter tank c12, an electric push rod 13 fixed to the top of the bracket 15, a flow regulating component 1 for separating and treating wastewater installed inside the purification tank 11, and a corresponding component for filtering inside the filter tank c12. The filter plate 19 is used for sealing and cleaning. The closing assembly 2 and the cleaning assembly 3 are used for this purpose. During use, wastewater is introduced into the filter box c12 via the inlet pipe 20. The wastewater undergoes preliminary filtration and purification through the filter plate 19 inside the filter box c12, removing larger solid impurities. The filtered and purified wastewater then flows downwards into the purification box 11. The bottom of the purification box 11 is temporarily sealed by the flow regulating assembly 1, allowing some wastewater to be temporarily stored inside. A certain amount of flocculant is introduced into the purification box 11 through the feed pipe b17, thereby reducing the amount of wastewater inside the purification box 11. The wastewater undergoes secondary purification. After secondary purification, the bottom of purification tank 2 (11) is opened via the flow regulating component 1, allowing the purified wastewater to flow downwards into purification tank 1 (5). Purifying agent solution is added to purification tank 1 (5), and the stirring component 4 within it agitates the wastewater, ensuring thorough and uniform mixing for further purification. This multi-stage purification process significantly reduces the burden of single-stage purification and avoids excessive waste of purifying agent, improving the efficiency and effectiveness of the purifying agent. The uniformity and thoroughness of wastewater contact and mixing effectively improve the quality of wastewater purification treatment. In this process, the wastewater is initially purified in small batches by the flow regulating component 1 before being put into the purification tank 5 for further purification treatment. The small batch inflow indicates that the matching purification agent can also be added in batches, so that each batch of wastewater can fully react with sufficient and fresh agent, avoiding the waste of agent and the risk of secondary pollution caused by adding too much agent at once. At the same time, it reduces the impact of wastewater flowing down into the purification tank 5, creating a relatively stable settling environment for subsequent purification, and the effluent water quality fluctuates less.While the electric push rod 13 drives the flow regulating component 1 to open, it simultaneously drives the closing component 2 to close the filter holes of the filter plate 19. The cleaning component 3 then evenly and finely blows air onto the filter plate 19, thereby cleaning the solid impurities filtered out on the filter plate 19. This automatic cleaning of the filter plate 19 prevents impurities from accumulating and clogging, ensuring its high filtration efficiency. Furthermore, closing the filter holes of the filter plate 19 before cleaning prevents impurities from falling into the purification tank 11 or the purification tank 5 during the cleaning process, thus avoiding secondary pollution of the water by solid impurities.

[0022] It is worth further explaining that flocculants such as polyaluminum chloride solution or polyacrylamide mixture can rapidly neutralize the negative charge of colloidal particles in water, causing them to "destabilize" and initially coagulate. Polyacrylamide, through the "bridging" effect of its long molecular chains, quickly adsorbs and bridges the initially coagulated small particles, forming large and dense flocs, thus accelerating sedimentation. The combined use of both can efficiently remove most suspended solids and some organic matter from water. Purification agents such as phosphorus removers, heavy metal chelators, and oxidants are also used. Phosphorus removers can be added with calcium or iron salts to form precipitates with phosphate ions in the water; heavy metal chelators can be added to chelate and precipitate heavy metal ions; and oxidants such as hydrogen peroxide can be added to decompose pollutants through strong oxidation.

[0023] Further as Figure 4 , Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, it is worth noting that the flow regulating component 1 includes an internal plate 101 fixed to the inner wall of the filter box c12. Multiple flow holes a102 are equidistantly distributed on the side of the internal plate 101. A shifting plate a107 is movably disposed above the internal plate 101. Multiple flow holes b108 are opened on the side of the shifting plate a107. The multiple flow holes b108 and the multiple flow holes a102 are staggered. A fixed [structure / structure] is located on the side of the shifting plate a107 near the internal plate 101. Multiple adjusting posts 103 are arranged in a one-to-one correspondence with multiple flow holes a102. A feed pipe b17, communicating with the interior of the purification chamber 11, is fixed to the side of the purification chamber 11. When the filter holes of the filter plate 19 are open, the adjusting plate a107 is at its lowest position, and the adjusting posts 103 on the adjusting plate a107 are inserted into the flow holes a102 to close them, thereby temporarily sealing the bottom of the purification chamber 11. After filtration and purification, the wastewater flows into purification tank 2 11, where a portion of the wastewater is temporarily stored. A certain amount of flocculant is added to purification tank 2 11 through feed pipe b17, thus performing secondary purification on the small amount of wastewater inside purification tank 2 11. After secondary purification, the electric push rod 13 moves the adjustment plate a107 upward, causing the adjustment column 103 to move out of the flow hole a102, opening the flow hole a102. The purified wastewater in purification tank 2 11 flows into purification tank 1 5 through flow hole b108 and flow hole a102 for further purification. The small batch inflow indicates that the matching purification agent can also be added in batches, ensuring that each batch of wastewater reacts fully with sufficient and fresh agent. This avoids agent waste and secondary pollution risks caused by adding too much agent at once, while also reducing the impact of wastewater flowing down into purification tank 1 5, creating a relatively stable settling environment for subsequent purification and resulting in smaller fluctuations in effluent quality.

[0024] Further as Figure 7 , Figure 10 and Figure 11 As shown, it is worth noting that the bottom of the adjusting column 103 is provided with a conical surface 104; it can be moved to different height positions by the adjusting plate a107. At this time, the conical surface 104 is located in the flow hole a102, thereby controlling the flow diameter of the flow hole a102 through the conical surface 104, thereby controlling the flow rate of sewage in the second purification box 11 more accurately, and controlling the rate at which sewage enters the first purification box 5, so as to be suitable for different purification requirements and purification scenarios.

[0025] Further as Figure 7As shown, it is worth noting that a rubber sleeve 105 is fitted onto the side of the adjusting post 103, and a guide slope 106 is provided at the bottom end of the rubber sleeve 105. In actual operation, the rubber sleeve 105 effectively improves the sealing effect of the adjusting post 103 on the flow hole a102, and the guide slope 106 plays a guiding role, so that the adjusting post 103 can be smoothly inserted into the flow hole a102.

[0026] Further as Figure 6 and Figure 9 As shown, it is worth noting that the cleaning component 3 includes a blower plate 305 embedded in the side wall of the filter box c12. The blower plate 305 has an inner cavity 306. The side of the blower plate 305 facing the inside of the filter box c12 has blower holes 307 that communicate with the inner cavity 306. There are multiple blower holes 307 that are equidistantly distributed. An air inlet pipe 310 that communicates with the inner cavity 306 is fixed on the side of the blower plate 305. An air pump is connected to the air inlet pipe 310. In operation, an airflow with a certain pressure is delivered to the inside of the blower plate 305 through the air inlet pipe 310. The airflow is then blown evenly and finely onto the top surface of the filter plate 19 through the multiple blower holes 307. This blows away the solid impurities filtered out on the filter plate 19, forming an automatic cleaning of the filter plate 19. This prevents impurities from accumulating and clogging on the filter plate 19, ensuring the high filtration efficiency of the filter plate 19.

[0027] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that a discharge port 308 is provided on the side of the filter box c12 opposite to the blower plate 305, and a guide groove 309 is fixed at the port of the discharge port 308. In actual operation, the airflow blows the solid impurities on the top surface of the filter plate 19 to the discharge port 308, and the common impurities are removed through the discharge port 308 and the guide groove 309.

[0028] Further as Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 11As shown, it is worth noting that the adjustment assembly 2 includes a movable and adjustable shift plate b201 located below the filter plate 19. A rubber pad 202 is fixedly attached to the top surface of the shift plate b201. Both the shift plate b201 and the rubber pad 202 have aligned flow holes c203 on their sides. These flow holes c203 are staggered with the filter holes on the filter plate 19. A connecting rod b204 is fixed to the side of the shift plate b201 and slides through the filter plate 19. The output end of the electric push rod 13 is fixed to the top end of the connecting rod b204. A connecting rod a109 is fixed between the shift plate b201 and the shift plate a107. In operation, the output end of the electric push rod 13 drives the connecting rod b204 upwards, thereby... The connecting rod b204 drives the shift plate b201, connecting rod a109, and shift plate a107 to move upward as a whole. At this time, the flow hole a102 opens, and the rubber pad 202 on the side of the shift plate b201 is pressed tightly against the bottom surface of the filter plate 19. Thus, the shift plate b201 and the rubber pad 202 seal the filter holes on the filter plate 19. The airflow is blown evenly and finely out through the air blowing hole 307 to the top surface of the filter plate 19, thereby blowing away the solid impurities filtered out on the filter plate 19. By sealing the filter holes of the filter plate 19 before blowing away impurities, it is possible to prevent impurities from falling into the purification box 2 11 or purification box 1 5 through the filter holes of the filter plate 19 during cleaning, thus avoiding secondary pollution of the water by solid impurities.

[0029] Further as Figure 4 , Figure 10 and Figure 11 As shown, it is worth noting that support rods a301 and b303 are fixed to the side of connecting rod b204. Baffles a302 and b304 are fixed to the ends of support rods a301 and b303, respectively, thereby sealing the discharge port 308 and the air blowing hole 307. When the inlet pipe 20 introduces wastewater into the filter box c12 and filters it through the filter plate 19, baffles b304 and a302 respectively seal the air blowing hole 307. The air outlet 307 and the waste outlet 308 are covered and sealed to prevent sewage from splashing into the air outlet 307 and the waste outlet 308, and to prevent sewage from leaking out and spreading to the outside. When the electric push rod 13 drives the connecting rod b204 to move upward, the connecting rod b204 drives the baffle a302 and the baffle b304 to move upward synchronously. At this time, the air outlet 307 and the waste outlet 308 are automatically opened, so that the airflow blown out of the air outlet 307 and the waste outlet 308 work together to blow away and clean the solid impurities on the filter plate 19.

[0030] Further as Figure 4 and Figure 6As shown, it is worth noting that a feed pipe a16 communicating with the interior of the purification chamber 5 is fixed to the side of the purification chamber 5. A stirring assembly 4 is installed inside the purification chamber 5. The stirring assembly 4 includes two stirring shafts 401 installed inside the purification chamber 5. Multiple stirring rods 402 are fixed to the sides of each stirring shaft 401. The bottom ends of the stirring shafts 401 are rotatably connected to the bottom side wall of the purification chamber 5. Gears 403 are fixed to the bottom ends of both stirring shafts 401, and the two gears 403 mesh with each other. A drive motor 404 is installed at the bottom of the purification chamber 5. The output end of the drive motor 404 is fixed to the bottom end of one of the stirring shafts 401. The output end of the drive motor 404 drives one of the stirring shafts 401 to rotate, and the two stirring shafts 401 rotate in opposite directions through the cooperation of two gears 403. Thus, the stirring rods 402 on the two stirring shafts 401 fully and evenly stir the sewage inside the purification tank 5. The purification agent liquid is transported and added into the purification tank 5 through the feed pipe a16, so that the purification agent and sewage are fully and evenly mixed, and the sewage is further purified.

[0031] This solution includes the following working process: Wastewater is transported into the filter box C12 through the inlet pipe 20. At this time, the baffles B304 and A302 respectively cover and seal the air blowing hole 307 and the waste discharge port 308 to prevent wastewater from splashing into the air blowing hole 307 and the waste discharge port 308. The wastewater undergoes preliminary filtration and purification treatment through the filter plate 19 inside the filter box C12, removing larger solid impurities. After filtration and purification, the wastewater flows downward into the purification box 11. At this time, the adjustment plate A107 is in the lowest position, and the adjustment pin 103 on the adjustment plate A107 is inserted into the flow hole A102 to seal the flow hole A102, thereby opening the bottom of the purification box 11. The system is temporarily closed, allowing some wastewater to be temporarily stored in purification tank 2 11. A certain amount of flocculant is added to purification tank 2 11 through feed pipe b17, thereby performing secondary purification on the small amount of wastewater inside purification tank 2 11. After secondary purification, the output end of electric push rod 13 drives connecting rod b204 to move upward, thereby driving the adjustment plate b201, connecting rod a109, and adjustment plate a107 to move upward as a whole, causing the adjustment column 103 to move out of flow hole a102, opening flow hole a102. The purified wastewater in purification tank 2 11 flows into purification tank 1 5 through flow hole b108 and flow hole a102 in sequence. The output of the motor 404 drives one of the stirring shafts 401 to rotate, and through the cooperation of two gears 403, drives the two stirring shafts 401 to rotate in opposite directions. This, in turn, causes the stirring rods 402 on the two stirring shafts 401 to thoroughly and evenly stir the wastewater inside the purification tank 5. Purification agent solution is then added to the purification tank 5 through the feed pipe a16, ensuring thorough and even mixing of the purification agent and wastewater for further purification. When the electric push rod 13 moves the connecting rod b204 upwards, the connecting rod b204 moves the baffles a302 and b304 upwards synchronously, automatically opening the air vent 307 and the waste discharge port 308. Air pressure is delivered to the blower plate 305 through the air inlet pipe 310, and then the air is blown out evenly and finely onto the top surface of the filter plate 19 through multiple blow holes 307, thereby cleaning the solid impurities filtered out on the filter plate 19 and forming an automatic cleaning of the filter plate 19. At this time, the rubber pad 202 on the side of the adjustment plate b201 is pressed tightly against the bottom surface of the filter plate 19, thereby sealing the filter holes on the filter plate 19 through the adjustment plate b201 and the rubber pad 202. By sealing the filter holes of the filter plate 19 before cleaning the impurities, it is possible to prevent impurities from falling into the purification box 2 11 or purification box 1 5 through the filter holes of the filter plate 19 during the cleaning process.

[0032] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the bottom of the purification tank 5 is fixed with multiple symmetrically distributed support legs 7, and the bottom ends of the multiple support legs 7 are jointly fixed with a base plate 8. The drive motor 404 is fixed to the top surface of the base plate 8. A drain pipe 6 is installed at the bottom of the purification tank 5. Valves 18 are installed on the drain pipe 6, the feed pipe a16 and the feed pipe b17. By opening the valve 18 on the drain pipe 6, the purified liquid in the purification tank 5 is discharged through the drain pipe 6.

[0033] Further as Figure 1 As shown, it is worth noting that a slot 9 is provided on the side of the purification box 5, and a cover plate 10 is sealed inside the slot 9. The cover plate 10 is hinged to the slot 9. By opening the cover plate 10, the inside of the purification box 5 can be easily inspected and maintained through the slot 9.

[0034] A method for treating wastewater using an ecological water supply channel includes the following steps: S1. The wastewater is initially filtered and purified by the filter plate 19 inside the filter box c12 to remove larger solid impurities. After filtration and purification, the wastewater flows downward into the purification box 11. At this time, the adjustment plate a107 is at its lowest position, and the adjustment pin 103 on the adjustment plate a107 is inserted into the flow hole a102 to close the flow hole a102, thereby temporarily closing the bottom of the purification box 11. This allows some wastewater to be temporarily stored in the purification box 11. A certain amount of flocculant is added into the purification box 11 through the feed pipe b17 to perform secondary purification on the small amount of wastewater inside the purification box 11. S2. After the secondary purification is completed, the output end of the electric push rod 13 drives the connecting rod b204 to move upward, thereby driving the adjustment plate b201, the connecting rod a109 and the adjustment plate a107 to move upward as a whole, so that the adjustment column 103 moves out of the flow hole a102 and the flow hole a102 is opened. The purified sewage in the second purification box 11 flows into the first purification box 5 through the flow hole b108 and the flow hole a102 in sequence. S3. The output end of the drive motor 404 drives one of the stirring shafts 401 to rotate, and the two gears 403 work together to drive the two stirring shafts 401 to rotate in opposite directions. The stirring rods 402 on the two stirring shafts 401 thoroughly and evenly stir the sewage inside the purification tank 5. The purification agent liquid is delivered and added to the purification tank 5 through the feed pipe a16, so that the purification agent and sewage are thoroughly and evenly mixed, and the sewage is further purified. S4. When the electric push rod 13 drives the connecting rod b204 to move upward, the connecting rod b204 drives the baffle a302 and b304 to move upward synchronously. At this time, the blowing hole 307 and the impurity discharge port 308 are automatically opened. The air with a certain air pressure is delivered to the inside of the blowing plate 305 through the air inlet pipe 310. The air is then blown evenly and finely onto the top surface of the filter plate 19 through multiple blowing holes 307, thereby cleaning the solid impurities filtered out on the filter plate 19.

[0035] S5. When cleaning the filter plate 19, the rubber pad 202 on the side of the adjustment plate b201 is pressed tightly against the bottom surface of the filter plate 19, thereby sealing the filter holes on the filter plate 19 through the adjustment plate b201 and the rubber pad 202. By sealing the filter holes of the filter plate 19 before blowing away impurities, it is possible to prevent impurities from falling into the purification box 2 11 or purification box 1 5 through the filter holes of the filter plate 19 during cleaning.

[0036] In summary: Wastewater undergoes preliminary filtration and purification via the filter plate 19 inside filter box C12. The purified wastewater then flows downwards into purification box 2 11. The bottom of purification box 2 11 is temporarily sealed by the flow regulating component 1, allowing some wastewater to be temporarily stored within it. This small amount of wastewater undergoes secondary purification. After secondary purification, the bottom of purification box 2 11 is opened again by the flow regulating component 1, allowing the purified wastewater to flow downwards into purification box 1 5. The stirring component 4 inside purification box 1 5 agitates the wastewater, ensuring thorough and uniform mixing of the purification agent and wastewater for further purification. This multi-stage wastewater purification process is achieved. The flow regulating component 1 allows wastewater to be pre-purified in small batches before being added to purification box 1 5 for further purification. This phased inflow indicates that the matching purification agent can also be used in stages. Batch dosing ensures that each batch of wastewater reacts fully with sufficient and fresh reagent, avoiding waste and secondary pollution risks caused by excessive dosing. It also reduces the impact of wastewater flowing into purification tank 5, creating a relatively stable settling environment for subsequent purification and resulting in less fluctuation in effluent quality. Simultaneously, the electric push rod 13 opens the flow regulating component 1, driving the closing component 2 to seal the filter holes of filter plate 19. The cleaning component 3 then evenly and finely blows air onto filter plate 19, cleaning the solid impurities filtered out. This automatic cleaning of filter plate 19 prevents accumulation and clogging, ensuring high filtration efficiency. Furthermore, sealing the filter holes before cleaning prevents impurities from falling into purification tank 11 or purification tank 5 during cleaning, thus avoiding secondary pollution of the water.

[0037] The electric linear actuator 13 and the drive motor can be purchased from the market. The electric linear actuator 13 and the drive motor are equipped with a power supply. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in the specification.

The wastewater is initially filtered and purified by the filter plate (19) inside the filter box c (12) to remove larger solid impurities. After filtration and purification, the wastewater flows downward into the purification box two (11). At this time, the adjustment plate a (107) is at the lowest position, and the adjustment column (103) on the adjustment plate a (107) is inserted into the flow hole a (102) to close the flow hole a (102), thereby temporarily closing the bottom of the purification box two (11), so that some wastewater is temporarily stored in the purification box two (11).

S2. After the secondary purification is completed, the output end of the electric push rod (13) drives the connecting rod b (204) to move upward, thereby driving the adjustment plate b (201), the connecting rod a (109) and the adjustment plate a (107) to move upward as a whole, so that the adjustment column (103) moves out from the flow hole a (102), the flow hole a (102) is opened, and the purified sewage in the second purification box (11) flows into the first purification box (5) through the flow hole b (108) and the flow hole a (102) in sequence.
