Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment, specifically to an artificial wetland wastewater treatment device. Background Technology
[0002] Constructed wetlands, as a highly efficient and low-consumption wastewater treatment technology, purify wastewater through the synergistic effects of physical filtration, chemical adsorption, and biodegradation. They are widely used in urban domestic sewage and industrial wastewater pretreatment. In existing technologies, activated carbon filters are often used as the core treatment unit to improve the removal efficiency of pollutants such as organic matter and heavy metals. While activated carbon, due to its rich pore structure and strong adsorption capacity, can effectively retain dissolved pollutants, it has revealed the following significant drawbacks in practical applications:
[0003] To meet the demand for large-volume water treatment, traditional constructed wetlands require large-area activated carbon filters. These filters are often laid vertically, which means that wastewater may only partially pass through the surface of the filter. This results in the effective adsorption area of the activated carbon filter not being fully utilized, and a large amount of wastewater is discharged without being fully adsorbed. This wastes activated carbon resources, significantly reduces the wastewater treatment effect, and makes it difficult to consistently achieve the expected purification goals.
[0004] Therefore, an artificial wetland wastewater treatment device is proposed. Utility Model Content
[0005] In view of the problems existing in the above-mentioned constructed wetland wastewater treatment devices, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide an artificial wetland wastewater treatment device, which solves the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An artificial wetland wastewater treatment device includes a treatment tank, a three-way pipe fixedly installed at the top center of the treatment tank, and a partition fixedly installed inside the treatment tank and below the three-way pipe.
[0009] The processing box is equipped with removable activated filters and isolation screens on both sides of the partition.
[0010] Both lower ends of the three-way pipe are fixedly provided with connecting pipes, both sides of the three-way pipe are fixedly provided with electromagnetic valves, both lower ends of the two connecting pipes are fixedly provided with hollow water outlet plates, both hollow water outlet plates have multiple evenly distributed water outlet holes on the side away from the partition, and both upper ends of the two hollow water outlet plates are fixedly provided with electric push rods, and the electric push rods are fixedly connected to the top of the treatment box.
[0011] Preferably, a pipe joint is fixedly provided at the upper end of the tee pipe.
[0012] Preferably, a zeolite-filled area is provided between the active filter and the isolation mesh.
[0013] Preferably, the connecting pipe is a rubber hose.
[0014] Preferably, both sides of the active filter and both sides of the isolation mesh are provided with first bolts, and the first bolts are threadedly connected to the inner side wall of the treatment box.
[0015] Furthermore, the processing box has openings on both sides, and each opening has a lid. The lid has second bolts on all four sides, and the second bolts are threaded to the side walls of the processing box. A drain pipe is fixedly installed at the bottom of the lid.
[0016] Preferably, both the electromagnetic valve and the electric actuator are electrically connected to an external controller.
[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0018] 1. This utility model, through the structural design of a three-way pipe, connecting pipe and hollow water outlet plate, allows sewage to be diverted through the three-way pipe. The height of the hollow water outlet plate is adjusted by an electric push rod, so that the sewage flows evenly from multiple evenly distributed water outlet holes to the activated filter screen in a planar manner, ensuring that the sewage fully contacts the surface of the activated carbon, improving the utilization rate of the effective adsorption area and improving the treatment effect of sewage.
[0019] 2. This utility model, through the electromagnetic valves installed on both sides of the three-way pipe, allows the electromagnetic valves on both sides of the three-way pipe to be opened and closed sequentially, ensuring that one side of the three-way pipe is connected while the other side is closed. This allows sewage to pass through the activated filter screen and isolation screen on both sides sequentially. When the activated filter screen and isolation screen on one side need to be cleaned, the activated filter screen and isolation screen on the other side are opened, ensuring continuous sewage treatment and improving sewage treatment efficiency.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] This utility model provides, for example Figure 1-4 An artificial wetland wastewater treatment device is shown, including a treatment box 1. A three-way pipe 2 is fixedly installed at the center of the top of the treatment box 1. A pipe connector 11 is fixedly installed at the upper end of the three-way pipe 2 and connected to an external wastewater pipe through the pipe connector 11. A partition 3 is fixedly installed inside the treatment box 1 and below the three-way pipe 2.
[0029] The processing box 1 is equipped with an active filter 4 and an isolation screen 5, which are detachable on both sides of the partition 3. A zeolite filling area is provided between the active filter 4 and the isolation screen 5. The active filter 4 and the isolation screen 5 are provided with first bolts 12 on both sides. The first bolts 12 are threaded to the inner wall of the processing box 1. The active filter 4 and the isolation screen 5 can be disassembled and assembled by means of the first bolts 12.
[0030] Both sides of the three-way pipe 2 are fixedly equipped with connecting pipes 6. The connecting pipes 6 are made of rubber hoses and can be freely extended and adjusted. Both sides of the three-way pipe 2 are fixedly equipped with electromagnetic valves 7. Both sides of the connecting pipes 6 are fixedly equipped with hollow water outlet plates 8. Both hollow water outlet plates 8 have multiple evenly distributed water outlet holes 9 on the side away from the partition plate 3. Both sides of the hollow water outlet plates 8 are fixedly equipped with electric push rods 10. The electric push rods 10 are fixedly connected to the top of the treatment box 1. Both the electromagnetic valves 7 and the electric push rods 10 are electrically connected to the external controller.
[0031] The treatment box 1 has openings on both sides, and each opening is equipped with a box cover 13. The four sides of the box cover 13 are equipped with second bolts 14, and the second bolts 14 are threadedly connected to the side walls of the treatment box 1. A drain pipe 15 is fixedly installed at the bottom of the box cover 13.
[0032] In use, through the structural design of the three-way pipe 2, connecting pipe 6 and hollow water outlet plate 8, the sewage is diverted through the three-way pipe 2 and then controlled by the electromagnetic valve 7 to flow to one side of the connecting pipe 6. The height of the hollow water outlet plate 8 is adjusted by the electric push rod 10 so that the sewage flows evenly from the water outlet hole 9 to the activated filter screen 4 in a planar manner, ensuring that the sewage fully contacts the surface of the activated carbon and improving the utilization rate of the effective adsorption area.
[0033] Meanwhile, the solenoid valves 7 on both sides of the three-way pipe 2 can be opened and closed in sequence, realizing the alternating use of the activated filter screen 4 and the isolation screen 5 on both sides. When one side needs to be cleaned, the other side can continue to work, ensuring continuous sewage treatment.
[0034] Wastewater is filtered through activated filter 4 to adsorb pollutants such as organic matter and heavy metals, and then separated by isolation net 5 to prevent particle loss. Combined with the ion exchange effect of the zeolite-filled area between the two, the purification effect is improved.
[0035] During maintenance, the activated filter 4, the isolation screen 5, and the tank cover 13 can be disassembled by the first bolt 12 and the second bolt 14, making it easy to replace components. The treated wastewater is finally discharged through the drain pipe 15 at the bottom of the tank cover 13, achieving an efficient and continuous wastewater treatment process.
