Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a multi-layer biological filter for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to measures taken to change the nature of wastewater so that it does not harm the environment or water bodies. In urban wastewater treatment, biological filters are a relatively effective method, which involves using microorganisms to degrade harmful components in wastewater.

[0003] Currently, the filter screens in some multi-layer biological filters are usually fixed. During the wastewater treatment process, a large amount of solid residue is generated. Because the filter screens in some multi-layer biological filters are not removable, they cannot effectively collect this residue. This not only affects the operating efficiency of the filter, but may also cause secondary pollution to the environment. Furthermore, the filter may become clogged due to untimely cleaning. Therefore, we propose a multi-layer biological filter for wastewater treatment to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a multi-layer biological filter for wastewater treatment, which has the following beneficial effects:

[0016] This invention involves wastewater entering a tank. Inside the tank, the wastewater first passes through a filter box to remove large particles and suspended solids. The first filter layer then performs preliminary biodegradation. The second filter layer further removes fine suspended solids and organic matter. The third filter layer magnetically adsorbs heavy metal ions and other magnetic substances from the wastewater, further improving the effluent quality. After filtration, the wastewater is discharged through a drain pipe by opening a valve. When the filter box needs to be removed, a movable plate is moved.

Two slots 6 are provided at the bottom of the sealing plate 4. A support plate 7 is fixedly connected to the right side of the tank body 1. Two T-shaped rods 8 are welded to the top of the support plate 7. A moving plate 9 is slidably connected to the two T-shaped rods 8. Two springs 10 are fixedly connected between the bottom of the moving plate 9 and the top of the support plate 7. Two locking pins 11 are welded to the top of the moving plate 9, and the locking pins 11 engage with the corresponding slots 6. A mesh plate 15 is fixedly connected inside the tank body 1. A first filter layer 16 is provided above the mesh plate 15, and a second filter layer 17 is provided at the bottom of the first filter layer 16. The bottom is equipped with a third filter layer 18. Wastewater enters the tank 1 through the inlet pipe 12. In the tank 1, the wastewater first passes through the filter box 3 to remove large particles and suspended solids. The first filter layer 16 performs preliminary biodegradation on the wastewater. The second filter layer 17 further removes fine suspended solids and organic matter from the wastewater. The third filter layer 18 magnetically adsorbs heavy metal ions and other magnetic substances in the wastewater, further improving the quality of the effluent. After filtration, the valve 14 is opened and the wastewater is discharged through the drain pipe 13. When it is necessary to remove the filter box 3, the moving plate 9 is moved. The moving plate 9 slides on the T-shaped rod 8 and compresses the spring 10. The moving plate 9 drives the locking pin 11 to move, so that the locking pin 11 separates from the corresponding locking groove 6. Then, the U-shaped handle 5 is grasped and pulled. The U-shaped handle 5 separates the filter box 3 from the tank 1 through the sealing plate 4, so that it can be easily disassembled and replaced, and can efficiently collect and treat solid residues in the wastewater.

[0025] In some embodiments, the spring 10 is movably sleeved on the corresponding T-shaped rod 8.

[0028] In some embodiments, the first filter layer 16 is anthracite filter media, the second filter layer 17 is quartz sand filter media, and the third filter layer 18 is magnetite filter media. The anthracite filter media has high porosity and good specific surface area, which can effectively intercept pollutants such as suspended solids, sediments, organic matter and microorganisms in the water, and improve the clarity of the water. The anthracite filter media also has a strong adsorption capacity, which can adsorb pollutants such as heavy metal ions, nitrogen and phosphorus, as well as organic matter and pigments in the water, further reducing the degree of water pollution.

[0029] In some embodiments, the movable plate 9 has two guide holes, and the movable plate 9 is slidably connected to the corresponding T-shaped rod 8 through the guide holes. The T-shaped rod 8 serves a positioning function.

[0030] Working principle or structural principle: During use, the entire device is fixed through the mounting holes 21 on the base 20. Wastewater enters the tank 1 through the inlet pipe 12. Inside the tank 1, the wastewater first passes through the filter box 3 to remove large particles and suspended solids. The first filter layer 16 performs preliminary biodegradation on the wastewater. The second filter layer 17 further removes fine suspended solids and organic matter from the wastewater. The third filter layer 18 magnetically adsorbs heavy metal ions and other magnetic substances in the wastewater, further improving the quality of the effluent. After filtration, the valve 14 is opened and the wastewater is discharged through the drain pipe 13. When it is necessary to remove the filter box 3, the moving plate 9 is moved. The moving plate 9 slides on the T-shaped rod 8 and compresses the spring 10. The moving plate 9 drives the locking pin 11 to move, so that the locking pin 11 separates from the corresponding locking groove 6. Then, the U-shaped handle 5 is grasped and pulled. The U-shaped handle 5 separates the filter box 3 from the tank 1 through the sealing plate 4, so that it can be easily disassembled and replaced, and can efficiently collect and treat solid residues in wastewater.
