Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The upper end of the mounting shell 51 is provided with an air inlet 53. The inner wall of the mounting shell 51 is fixedly connected to a filter layer 54, and the inner wall of the filter layer 54 is fixedly connected to an ultrafiltration membrane 55. A water inlet 56 is provided on the top of one side of the shell 1, and a water outlet 57 is provided through the lower end of the mounting shell 51. The upper end of the mounting plate 2 is fixedly connected to both sides of the lower end of the shell 1, and the inner wall of the mounting plate 2 is movably connected to the outer wall of the fixing bolt 3;

[0024] The bottom sides of the shell 1 are fixedly installed with mounting plates 2. After the shell 1 is moved to a suitable position, the fixing plates and the shell 1 are stabilized by fixing bolts 3. Then the staff puts the wastewater into the water inlet pipe 6 and introduces it into the mounting shell 51. The wastewater flows into the filter layer 54 and the ultrafiltration membrane 55 through the water inlet pipe 6. The wastewater flows in through the water inlet 56. The gas flows into the air inlet 53 through the air inlet pipe 4, so that the gas can pressurize the wastewater, so that the wastewater passes through the filter layer 54 and the ultrafiltration membrane 55 for filtration. The ultrafiltration membrane 55 is reinforced by the inner lining to prevent impurities in the wastewater from scratching the membrane wall. When the water filtration is completed, the filtered water passes through the water outlet 57, and the water outlet 57 flows the water into the drain pipe 8. When the water filtration is completed, the staff controls and starts the water pump 74 to make the pure water in the water tank 71 flow from the connecting pipe 75 and the bending pipe 76 into the atomizing nozzle 77, and then flows into the filter layer 54 and the ultrafiltration membrane 55 through the clean water injection port 52 to clean the filter layer 54 and the ultrafiltration membrane 55 to prevent excessive impurities in the ultrafiltration membrane 55.

[0025] See also Figure 2 In order to quickly filter the wastewater in the housing 1, the upper ends of the mounting shell 51 are connected to the outer walls of the water purification inlet 52, and the upper end of the mounting shell 51 is connected to the outer wall of the air inlet 53. The water purification inlet 52 is symmetrically located on both sides of the upper end of the mounting shell 51 and is compatible with the atomizing nozzle 77.

[0026] In order to further improve the efficiency of wastewater treatment, the setting of the water tank 71 fully considers the recycling and convenient operation of water. The water tank 71 not only serves as a storage container for pure water, but also adds new pure water at any time through the setting of the water adding pipe 72, ensuring the sufficiency and freshness of the water source. The plug 73 at the upper end of the water adding pipe 72 effectively prevents dust and other impurities from entering the water tank 71, ensuring the purity of the water quality. When the water pump 74 is started, it will pump the pure water in the water tank 71 through the connecting pipe 75 to the bent pipe 76. The L-shaped setting of the bent pipe 76 cleverly guides the direction of the water flow, so that the water flow can be more evenly distributed on the filter layer 54. The atomizing nozzle 77 connected to the lower end of the bending tube 76 can refine the water flow into tiny droplets. These droplets can more fully contact the filter layer 54, thereby improving the cleaning efficiency. At the same time, the atomized water flow can also effectively reduce the impact of the water flow on the filter layer 54, thereby extending the service life of the filter layer 54. In addition, the control panel 9 is responsible for controlling the start and stop of the water pump 74 and the operating status of the monitoring device. The staff only needs to simply operate the buttons or knobs on the control panel 9 to control the entire wastewater treatment process, making the operation simple and quick, greatly improving the work efficiency, and realizing the effective treatment of wastewater and the cleaning effect of pure water.

[0027] See also Figure 3 In order to quickly spray pure water on the filter layer 54, the water injection mechanism 7 includes a water tank 71, one side of the water tank 71 is fixedly connected to one side of the shell 1, a water supply pipe 72 is provided on the upper end of the water tank 71, and a plug 73 is provided on the upper end of the water supply pipe 72. A water pump 74 is bolted to the bottom wall of the inner cavity of the water tank 71, and a connecting pipe 75 is fixedly connected to the upper end of the water pump 74. One end of the connecting pipe 75 is connected through a bent pipe 76, and the lower end of the bent pipe 76 is fixedly connected to an atomizing nozzle 77. The upper end of the water tank 71 is connected through the lower end of the water supply pipe 72, and the upper end of the water supply pipe 72 is threadedly connected to the lower end of the plug 73. The shape of the bent pipe 76 is L-shaped;

[0028] When the wastewater treatment is started, the operating parameters such as the air intake pressure and the water intake flow rate are preset through the control panel 9 to ensure the efficiency and stability of the entire recycling process. Subsequently, the wastewater enters the shell 1 through the water inlet 56 and flows through the water inlet pipe 6 of the mounting shell 51 under the action of gravity and enters the interior of the mounting shell 51. The wastewater first contacts the filter layer 54, which is composed of fine materials and can effectively intercept large particles of impurities and suspended matter in the wastewater to preliminarily purify the water quality. Then, the wastewater that has undergone preliminary filtration passes through the ultrafiltration membrane 55. The ultrafiltration membrane 55, with its unique pore structure, further removes harmful substances such as tiny particles, colloids, bacteria and some viruses in the water, thereby significantly improving the water quality. At the same time, the air intake pipe 4 continuously injects compressed air into the mounting shell 51 to form a certain airflow pressure, which promotes the uniform distribution and rapid penetration of the wastewater on the filter layer 54 and the ultrafiltration membrane 55, thereby accelerating the filtration process. After 53 enters the installation shell 51, it can also help purge the surface of the ultrafiltration membrane 55 to prevent the occurrence of blockage 73 and extend its service life. As the filtration process continues, the purified water flows out from the water outlet 57 at the lower end of the installation shell 51 and is discharged out of the device through the drain pipe 8 for subsequent treatment or direct reuse. The solid waste and intercepted pollutants in the wastewater gradually accumulate on the surface of the filter layer 54 and the ultrafiltration membrane 55 to form a filter cake layer. In order to maintain the filtration efficiency and the normal operation of the device, when it is detected that the filtration effect has decreased or the preset cleaning cycle has been reached, the water injection mechanism 7 is automatically started to inject cleaning liquid or clean water into the shell 1 to backwash or soak the filter layer 54 and the ultrafiltration membrane 55 to remove the pollutants and impurities attached thereto. After cleaning, the wastewater treatment returns to normal working state, and the wastewater treatment and carbon filter membrane recovery operations can be continued, thereby achieving efficient purification of wastewater and effective recycling and reuse of carbon filter membranes.

[0029] Working principle: First, the mounting plates 2 are fixed on both sides of the bottom of the shell 1. After the shell 1 is moved to a suitable position, the fixing plates and the shell 1 are stabilized by fixing bolts 3. Then the staff puts the wastewater into the water inlet pipe 6 and introduces it into the mounting shell 51. The wastewater flows into the filter layer 54 and the ultrafiltration membrane 55 through the water inlet pipe 6. The wastewater flows in through the water inlet 56. The gas flows into the air inlet 53 through the air inlet pipe 4, so that the gas can pressurize the wastewater, so that the wastewater passes through the filter layer 54 and the ultrafiltration membrane 55 for filtration. The ultrafiltration membrane 55 is strengthened by the lining to avoid wastewater. The impurities in the membrane wall are scratched. When the water filtration is completed, the filtered water passes through the water outlet 57, and the water flows into the drain pipe 8 through the water outlet 57. When the water filtration is completed, the staff controls and starts the water pump 74 to make the pure water in the water storage tank 71 flow from the connecting pipe 75 and the bending pipe 76 into the atomizing nozzle 77, and then flows into the filter layer 54 and the ultrafiltration membrane 55 through the clean water injection port 52 to clean the filter layer 54 and the ultrafiltration membrane 55 to prevent excessive impurities in the ultrafiltration membrane 55. In order to further improve the efficiency of wastewater treatment, the setting of the water storage tank 71 fully considers the recycling of water and The water tank 71 is convenient to operate. It is not only a storage container for pure water, but also can be used to add new pure water at any time through the setting of the water adding pipe 72, ensuring the sufficiency and freshness of the water source. The plug 73 at the upper end of the water adding pipe 72 effectively prevents dust and other impurities from entering the water tank 71, ensuring the purity of the water quality. When the water pump 74 is started, it will pump the pure water in the water tank 71 through the connecting pipe 75 to the bending pipe 76. The L-shaped setting of the bending pipe 76 cleverly guides the direction of the water flow, so that the water flow can be more evenly distributed on the filter layer 54, and the atomizing nozzle 77 connected to the lower end of the bending pipe 76 , can refine the water flow into tiny droplets, these droplets can more fully contact with the filter layer 54, improve the cleaning efficiency, at the same time, the atomized water flow can also effectively reduce the impact of the water flow on the filter layer 54, extending the service life of the filter layer 54, in addition, the control panel 9 is responsible for controlling the start and stop of the water pump 74, and monitoring the operating status of the device. The staff only needs to simply operate the buttons or knobs on the control panel 9 to achieve control of the entire wastewater treatment process, making the operation simple and quick, greatly improving the work efficiency, and achieving effective treatment of wastewater and the cleaning effect of pure water;

[0030] Then, when the wastewater treatment is started, the operating parameters such as the air intake pressure and the water intake flow rate are preset through the control panel 9 to ensure the efficiency and stability of the entire recycling process. Subsequently, the wastewater enters the shell 1 through the water inlet 56 and flows through the water inlet pipe 6 of the installation shell 51 under the action of gravity and enters the interior of the installation shell 51. The wastewater first contacts the filter layer 54, which is composed of fine materials and can effectively intercept large particles of impurities and suspended matter in the wastewater, and preliminarily purify the water quality.
