[0002] Ecological filters are a novel ecological wastewater treatment technology developed based on biological filters and constructed wetlands. Ecological filters primarily purify pollutants in wastewater through the combined effects of interception and adsorption by the filter media, oxidative decomposition by microorganisms attached to the media, and absorption and transformation by filter plants. Combining the advantages of both biological filters and constructed wetlands, ecological filters offer significant comparative advantages in terms of investment cost, operating costs, purification effect, land area, ecological benefits, and ease of operation. Therefore, they are widely used in the treatment of domestic sewage, livestock wastewater, wastewater treatment plant effluent, and industrial wastewater.

[0003] Existing ecological filter devices for wastewater treatment often place packing materials of different particle sizes below the vegetation zone, allowing wastewater to be purified step by step through these different packing materials. However, this type of ecological filter makes it inconvenient to replace the packing materials, and prolonged use of the same packing material can lead to poor actual purification results. Utility Model Content

[0033] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0034] Reference Figures 1-3 This embodiment provides a filter tank, including a tank body 100. A purification mechanism 200 is installed inside the tank body 100 to purify water. The purification mechanism 200 includes an outer frame 210 with multiple placement spaces 220. Each placement space 220 contains a removable placement frame 230, and at least one placement frame 230 contains packing material. The packing material is mainly used for filtration and sedimentation to remove pollutants. The outer frame 210 is connected to a lifting mechanism, which drives the outer frame 210 to rise from inside the tank body 100 to outside. Raising the outer frame 210 to the outside of the tank body 100 via the lifting mechanism allows operators to easily remove the placement frames 230 from the placement spaces 220, thereby replacing the packing material in the placement frames 230, avoiding prolonged use of the same packing material, and improving the water purification effect.

[0035] As one implementation method of the lifting mechanism, such as Figure 1 As shown, the lifting mechanism includes a drive device 310, a transmission device 320, and a driven device 330. The drive device 310 is installed on the top of the pool body 100, and the driven device 330 is installed on the bottom of the outer frame 210. The drive device 310, the transmission device 320, and the driven device 330 are connected in a transmission manner. When the drive device 310 operates, it drives the transmission device 320 to operate, which in turn drives the driven device 330 to rise, thereby raising the bottom of the outer frame 210 to the outside of the pool body 100.

[0036] It is understandable that when the drive unit 310 runs in reverse, it can drive the outer frame 210 down into the interior of the pool body 100.

[0037] Specifically, in a preferred embodiment, the driving device 310 is a drive motor, the transmission device 320 is a threaded rod, and the driven device 330 is a threaded slider that matches the threaded rod. The drive motor is mounted on the top of the pool body 100 via a fixed base 110. The output end of the drive motor is connected to the threaded rod, and the threaded slider is threadedly connected to the threaded rod. A mounting groove is provided at the bottom of the pool body 100, and the end of the threaded rod is rotatably connected to the mounting groove. Bearings are provided inside the fixed base 110 and the mounting groove. The output shaft of the drive motor is connected to the fixed base 110 via the bearings, and the end of the threaded rod is rotatably connected to the mounting groove via the bearings. When the drive motor rotates forward, it drives the threaded rod to rotate forward, causing the threaded slider to move upward and raising the outer frame 210. Correspondingly, when the drive motor rotates in reverse, the outer frame 210 descends.

[0038] It should be noted that four lifting mechanisms are set up, located at the four corners of the outer frame 210. At this time, when the outer frame 210 is raised or lowered, it is necessary to control the four drive devices 310, i.e., drive motors, to operate synchronously.

[0039] Of course, in some other embodiments, a single lifting mechanism can be provided, with sliding shafts vertically installed at the other three corners of the outer frame 210, and corresponding sliders installed at the bottom of the outer frame 210, the sliders being slidably connected to the sliding shafts. The number of lifting mechanisms can also be two or three, and the number of sliding shafts can be increased or decreased as needed.

[0040] It is understandable that the lifting mechanism has a certain self-locking capability, allowing it to remain stationary and locked when the outer frame 210 is raised to a designated position outside the pool body 100, facilitating the replacement of packing material by operators. Specifically, in some embodiments, the threaded rod and threaded slider themselves possess a certain self-locking capability. To improve the self-locking capability of the threaded rod and slider, a self-locking mechanism can be added. For example, pin holes can be provided on both the threaded slider and the threaded rod. When the threaded slider moves to the designated position, a pin is inserted into the pin hole, causing the threaded slider and threaded rod to self-lock.

[0041] In some embodiments, the lifting mechanism may also adopt a structure of a drive motor and a rack and pinion pair. The drive motor drives the gear to rotate, causing the rack to move linearly, thereby raising or lowering the outer frame 210. Alternatively, a structure of a drive motor and a chain may be adopted, where the drive motor rotates, driving the chain to lift or lower the outer frame 210. The specific implementation methods are clear to those skilled in the art and will not be described in detail here.

[0042] To facilitate the removal of the placement frame 230 from the placement space 220, in some embodiments, the placement frame 230 is slidably connected to the placement space 220. Furthermore, multiple sets of pulleys are provided at the connection between the placement frame 230 and the placement space 220 to increase the smoothness of the sliding motion. It should be noted that the placement frame 230 is locked when pushed into the placement space 220; it is unlocked first and then pulled out when removing it. The placement frame 230 can be locked using a pin structure, for example, by providing a pin hole in the placement frame 230 and a corresponding latch on the outer frame 210, locking the placement frame 230 after it enters the placement space 220 using the latch.

[0043] As one embodiment of the purification mechanism 200 of the ecological filter, such as Figure 2 and Figure 3As shown, the outer frame 210 has four placement spaces 220 from top to bottom. The corresponding placement frames 230 are respectively equipped with a plant stabilization layer 231, a purification and deodorization layer 232, a coupling and decontamination layer 233, and a reinforced interception layer 234. These multiple purification layers achieve multi-directional purification of wastewater, improving the purification effect. It should be noted that more than four placement spaces 220 can be provided depending on the depth of the pool body 100. A sealing strip is provided on the outer edge of the placement frame 230 (where it connects with the placement space 220). When the placement frame 230 enters the placement space 220, the sealing strip seals the gap between the placement frame 230 and the placement space 220, reducing the risk of wastewater leakage during filtration.

[0044] The plant stabilization layer 231 is filled with planting soil, which stabilizes the plant growth environment and provides necessary nutrient support. The purification and deodorization layer 232 is filled with porous mineral filler to intercept odors and effectively remove pollutants from wastewater. The coupled decontamination layer 233 is filled with enhanced denitrification and phosphorus removal coupled filler to efficiently remove nitrogen and phosphorus from wastewater using biological processes. The enhanced interception layer 234 is filled with large-particle inert filler with a particle size of 30-50mm, which mainly removes pollutants through filtration and sedimentation.

[0045] Understandably, to facilitate sewage flow, the top of the outer frame 210 has an opening. An inlet pipe connects to the inlet of the pool 100, leading to the opening in the outer frame 210. Sewage flows into the pool 100 from the inlet, then flows downwards through the opening in the outer frame 210 into each placement frame 230, where it is purified and filtered by the packing material. The bottom of each placement frame 230 has a through-hole for downward sewage flow; the diameter of the through-hole is smaller than the diameter of the packing material to prevent leakage. When the purification mechanism 200 is located inside the pool 100, there is a certain gap between the bottommost placement frame 230 and the bottom of the pool 100, facilitating the discharge of purified sewage from the purification mechanism 200.

[0046] The water inlet pipe is detachably connected to the water inlet of the pool body 100. When the packing needs to be replaced, the water inlet pipe is detached to prevent interference when the outer frame 210 is removed.

[0047] It should be noted that the inner wall of the pool body 100, the purification mechanism 200 and the lifting mechanism are all treated with anti-corrosion measures, such as using anti-corrosion materials or anti-corrosion sealing treatment.

[0048] Another aspect of this application provides an ecological filter system, such as Figure 4As shown, the system includes two filter tanks as described above. In the water flow direction, the output port of the filter tank located at the front is connected to the input port of the filter tank located at the rear via a conveying pipe 400. The filter tank located at the front has an input port connected to an input pipe 120, located near the top of the tank, while the output port is located near the bottom of the tank. The conveying pipe 400 is connected to a first outlet pipe 500 via a T-shaped pipe, and the output port of the filter tank located at the rear is connected to a second outlet pipe 600. Water pumps 700 are installed on the conveying pipe 400, the first outlet pipe 500, and the second outlet pipe 600, serving as the power element for conveying the water flow. A first control valve 410 and a second control valve 510 are respectively installed on the conveying pipe 400 and the first outlet pipe 500, controlling the opening and closing of the conveying pipe 400 and the first outlet pipe 500, respectively.

[0049] Wastewater first enters the upstream filter tank for purification via inlet pipe 120. After passing the test, the purified water is discharged from the first outlet pipe 500. If the test fails, the first control valve 410 is opened and the second control valve 510 is closed, allowing the wastewater to be transported to the downstream filter tank for further purification until the wastewater passes the test and is discharged from the second outlet pipe 600.

[0050] As one implementation method for wastewater testing, a water quality detection probe 810 is installed on the conveying pipe 400 and the second outlet pipe 600 to detect the water quality of the water flowing in the pipe. The water quality detection probe 810, the first control valve 410, and the second control valve 510 are all electrically connected to the water quality testing equipment 800. The water quality detection probe 810 transmits the water quality detection signal to the water quality testing equipment 800. The water quality testing equipment 800 is equipped with a control module and a remote command module. The remote command module remotely transmits the signal to the remote receiving module inside the first control valve 410 or the second control valve 510. The output end of the remote receiving module is equipped with an execution module, which is used to drive the first control valve 410 or the second control valve 510 to move.

[0051] The operation process of this ecological filter system is as follows:

[0052] Wastewater first enters the front filter tank through the input pipe 120. The wastewater passing through the front filter tank is purified by the plant stabilization layer 231, purification and deodorization layer 232, coupling decontamination layer 233 and enhanced interception layer 234 set inside the purification mechanism 200. The water quality inside the delivery pipe 400 is detected by the water quality detection probe 810.

[0053] The first control valve 410 and the second control valve 510 are controlled by the water quality testing equipment 800.

[0054] When the water quality detection probe 810 installed on the surface of the conveying pipeline 400 detects that the water quality is qualified, the first control valve 410 is closed and the second control valve 510 is opened, so that the water flows to the first outlet pipe 500 and is discharged through the first outlet pipe 500 for the secondary use of sewage.

[0055] When the water quality detection probe 810 installed on the surface of the conveying pipeline 400 fails to meet the test results, the second control valve 510 is closed and the first control valve 410 is opened, so that the water flows into the filter tank on the rear side. The water is then purified for a second time through the filter tank on the rear side. After the water passes the purification test, it is discharged through the second outlet pipe 600 for secondary reuse of the wastewater.

[0056] Understandably, the above process is based on the premise that the water quality has passed a second test, and the number of downstream filter tanks can be increased according to the actual situation.
