[0002] Wastewater treatment is the process of purifying pollutants in wastewater to remove or reduce their levels, ensuring compliance with discharge standards or reusability. Treatment typically involves physical, chemical, and biological methods to minimize the impact of wastewater on the environment and public health. By removing pollutants from wastewater, pollution of water, soil, and air is reduced, protecting the ecological environment and biodiversity. Pathogens, toxins, and other harmful substances in wastewater are removed, reducing threats to human health. Treated wastewater can be reused for industrial cooling, irrigation, and other purposes, conserving water resources and promoting sustainable development. Complying with environmental regulations and standards is essential to avoid the legal and economic risks associated with illegal discharge. Wastewater treatment improves the living environment, reduces odors, sewage accumulation, and other issues associated with wastewater, and enhances residents' quality of life.

[0022] Treatment tank: This square tank houses all the wastewater treatment components. It has an outlet and a return pipe on either side of the bottom. The outlet discharges filtered wastewater, while the return pipe redirects filtered wastewater back to the top of the tank for multiple filtration cycles.

[0023] Filter assembly: The filter assembly consists of several layers, including a coarse filter layer, a fine filter layer, an activated carbon filter layer, and a membrane filter layer. Each filter layer is equipped with a support shell outside. These shells not only provide structural support but also ensure that each layer can work stably:

The treatment tank 10 is a square tank structure. The interior of the treatment tank 10 is sequentially provided with filtering assemblies 20 from top to bottom. The filtering assembly 20 is used to filter the wastewater input from the top of the treatment tank 10; the bottom of the treatment tank 10 is provided with a water outlet 30 and a reflux pipe 40 on both sides. The water outlet 30 is used to discharge the filtered wastewater inside the treatment tank 10, and the reflux pipe 40 is used to re-input the filtered wastewater in the treatment tank 10 from the top of the treatment tank 10 for multiple filtration; the treatment tank 10 is connected to the reflux pipe 40, and the connection position is provided with a water pump 50. The water pump 50 is used to pump the wastewater at the bottom of the treatment tank 10 into the reflux pipe 40.

[0038] In the above technical solution, a square groove is provided on the side wall of the processing tank 10 , and the size of the square groove matches the cross-sectional size of the filter assembly 20 .

[0039] Furthermore, in the above technical solution, the filter assembly 20 includes a coarse filter layer 21, a fine filter layer 22, an activated carbon filter layer 23 and a membrane filter layer 24. The coarse filter layer 21, the fine filter layer 22, the activated carbon filter layer 23 and the membrane filter layer 24 are all fixed with a shell on the outside, and the shell is used to support the coarse filter layer 21, the fine filter layer 22, the activated carbon filter layer 23 and the membrane filter layer 24.

[0040] Furthermore, in the above technical solution, the coarse filter layer 21 and the fine filter layer 22 are mesh structures, wherein the mesh diameter of the coarse filter layer 21 is larger than the mesh diameter of the fine filter layer 22 .

[0041] Furthermore, in the above technical solution, the meshes of the coarse filter layer 21 and the fine filter layer 22 are staggered to prevent the wastewater from passing through the filter assembly 20 too quickly, resulting in poor filtering effect.

[0042] Furthermore, in the above technical solution, the membrane filtration layer 24 is a hollow fiber membrane, and the hollow fiber membrane is made of polyvinylidene fluoride, which is used to intercept suspended matter and microorganisms in wastewater.

[0043] Furthermore, in the above technical solution, a handle is provided on one side of the housing to facilitate installation and removal of the filter assembly 20 from the square groove.

[0044] Furthermore, in the above technical solution, a sliding groove is provided at the position where the square groove is slidably connected to the filter assembly 20 , and the sliding groove is used to limit the sliding direction of the filter assembly 20 .

[0045] Furthermore, in the above technical solution, the side of the reflux pipe 40 away from the bottom of the processing tank 10 is fixed at the top of the processing tank 10 and is arranged tangentially to the side wall of the processing tank 10 .

[0046] Furthermore, in the above technical solution, the shell is made of aluminum alloy.

[0047] Coarse filter layer: Wastewater first passes through the coarse filter layer, which uses a mesh structure to capture larger particles and solid matter and protect subsequent filter components.

[0048] Fine filtration layer: The wastewater then flows through the fine filtration layer, which has smaller meshes to remove smaller particles and further improve water quality.

[0049] Activated carbon filter layer: When wastewater passes through the activated carbon filter layer, the activated carbon will absorb organic matter, odor and some chemical pollutants in the water, and remove harmful components in the wastewater.

[0050] Membrane filtration layer: Finally, the wastewater passes through the membrane filtration layer. The pore size of this layer is extremely small, which can intercept suspended matter, bacteria, viruses and other tiny pollutants, providing the most delicate filtration.

[0051] Wastewater return and circulation:

[0052] Backflow pipe: The treated wastewater is introduced into the top of the treatment tank through the backflow pipe and filtered multiple times to ensure that the wastewater is fully treated.

[0053] Outlet: The treated wastewater is discharged through the outlet. Usually, a final test is carried out before discharge to ensure that the water quality meets the standards.

[0054] Specifically, the principle of this utility model is as follows: Before use, ensure that the treatment tank and its various components (such as the filter assembly and reflux tube) are properly installed and in good condition. Check that the wastewater source is connected to the water inlet of the device and ensure that all pipes and valves are in normal working order. Turn on the power switch of the device and start the water pump. The water pump draws wastewater from the water inlet into the treatment tank. Adjust the pump flow rate to ensure that the wastewater enters the treatment tank at an appropriate rate.

[0055] The wastewater passes through various filter components within the treatment tank. The coarse filter first removes large particles, followed by the fine filter, which further removes smaller particles. The activated carbon filter absorbs organic matter and some chemical contaminants. Finally, the membrane filter provides fine filtration, removing suspended solids and microorganisms.

[0056] Treated wastewater is reintroduced into the top of the treatment tank via a backflow pipe to ensure that the wastewater has passed through multiple filtration stages. Ensure that the backflow pipe and pump are functioning properly to prevent premature discharge of wastewater.

[0057] When the treatment is completed, open the outlet at the bottom of the tank to discharge the treated wastewater. Before draining, check whether the water quality meets the requirements.

[0058] Regularly check and clean the filter components, especially the activated carbon filter layer and membrane filter layer, to prevent clogging and reduced treatment efficiency.
