[0013] Compared with the prior art, the beneficial effects of this utility model are: the biological treatment device of the wastewater treatment plant biochemical system not only greatly improves the treatment effect of wastewater during use, but also allows the treatment device to collect impurities in the wastewater together, making it convenient for users to remove the MBR flat sheet membrane from the inside of the fixed box and disassemble and clean the surface of the MBR flat sheet membrane, thus improving the treatment effect of wastewater, but also allows the treatment device to monitor the water level in the treatment liquid tank at any time during use, avoiding the phenomenon of insufficient water level in the treatment liquid tank during the use of the treatment device;

[0014] 1. By setting up a high-efficiency screening mechanism, the electric push rod inside the fixed cylinder is controlled to work. Under the action of the electric push rod, the moving column is driven to slide inside the guide slide groove. Under the action of the guide slide groove, the moving column is guided. At this time, the moving column drives the screening box to slide inside the groove. Under the action of the groove, the moving position of the mixing box is guided, avoiding the phenomenon of the screening box tilting when moving. Thus, the garbage and impurities in the wastewater are screened inside the screening box, realizing the function of the treatment device for vibrating screening of wastewater. This greatly improves the treatment effect of the treatment device when it is used, and enables the treatment device to collect the impurities in the wastewater together.

[0015] 2. With a convenient disassembly and assembly mechanism, users can periodically replace the MBR flat sheet membrane. The user rotates the rotating plate on the L-shaped frame, causing it to move the positioning clip away from the positioning slot. Then, the user pulls the MBR flat sheet membrane, moving it inside the fixed box. At this time, the MBR flat sheet membrane causes the connecting block to slide inside the L-shaped frame, guiding the membrane and allowing it to be pulled out of the fixed box for replacement and cleaning. This facilitates easy replacement of the MBR flat sheet membrane, allowing users to easily remove it from the fixed box and clean its surface, resulting in better wastewater treatment.

[0016] 3. By incorporating a water level monitoring mechanism, the float moves downwards as the volume of treated liquid in the tank decreases. Simultaneously, the float drives the float rod to slide along the inner wall of the monitoring box. The float rod slides within the tank and is guided by the tank's structure. As the float rod moves downwards, it causes the alarm contact plate to contact the surface of the alarm on the inner wall of the monitoring box. When the contact plate contacts the alarm, the alarm automatically sounds, indicating that the water level in the treated liquid tank is too low and that water needs to be added to the tank promptly via the feed cylinder. This system enables the treatment device to monitor the water level in the tank, allowing for continuous monitoring and preventing the water level from becoming too low during operation.

The high-efficiency screening mechanism 2 includes a fixed cylinder 21, a guide groove 22, and a high-efficiency screening component 23. The high-efficiency screening component 23 is disposed on the inner wall of the device housing 1 and the surface of the screening box 110. The high-efficiency screening component 23 is composed of a groove 231, a moving column 232, and an electric push rod 233. The inner wall of the device housing 1 is provided with grooves 231, which slide in contact with the surface of the screening box 110. The inner wall of the device housing 1 is equipped with a fixed cylinder 21. A movable column 232 is provided, with one end of the movable column 232 extending above the fixed cylinder 21.

[0026] During implementation, the electric push rod 233 inside the control fixed cylinder 21 is operated. Under the action of the electric push rod 233, the moving column 232 is driven to slide inside the guide groove 22. Under the action of the guide groove 22, the moving column 232 is guided.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, the inner wall of the fixed box 120 and the surface of the MBR flat membrane layer 121 are provided with a convenient disassembly and assembly mechanism 3. The convenient disassembly and assembly mechanism 3 includes an L-shaped frame 31, a rotating plate 32, and a convenient disassembly and assembly assembly 33. The convenient disassembly and assembly assembly 33 is located on the inner wall of the fixed box 120 and the surface of the MBR flat membrane layer 121. The convenient disassembly and assembly assembly 33 is composed of a positioning clip 331, a positioning slot 332, and a connecting block 333.

[0028] During implementation, the user rotates the rotating plate 32 on the surface of the L-shaped frame 31, causing the rotating plate 32 to move the positioning clip 331 away from the inside of the positioning clip slot 332. Subsequently, the user pulls the MBR flat membrane layer 121, causing the MBR flat membrane layer 121 to move inside the fixed box 120. At this time, the MBR flat membrane layer 121 drives the connecting block 333 to slide inside the L-shaped frame 31.

[0029] Furthermore, such as Figure 2 and Figure 5 As shown, a water volume monitoring mechanism 4 is provided on the surface of the treatment liquid tank 104. The water volume monitoring mechanism 4 includes a float plate 41, a monitoring box 42, a float rod 43, a tank 44, an alarm plate 45, and an alarm 46. The monitoring box 42 is installed on the surface of the top of the treatment liquid tank 104. The float rod 43 is installed inside the monitoring box 42. The float rod 43 slides and engages with the inner wall of the monitoring box 42. One end of the float rod 43 passes through the treatment liquid tank 104 and extends into the interior of the treatment liquid tank 104. The float rod 43 slides and engages with the inner wall of the treatment liquid tank 104. The float plate 41 is installed inside the treatment liquid tank 104.

An alarm 46 is installed on the inner wall of the monitoring box 42. The alarm 46 and the alarm plate 45 engage with each other.

[0030] During implementation, the float plate 41 moves downward as the amount of treated liquid inside the treatment tank 104 decreases. At this time, the float plate 41 drives the float rod 43 to slide on the inner wall of the monitoring box 42. The float rod 43 slides inside the tank 44 and is guided by the tank 44. When the float rod 43 moves downward, it drives the alarm piece 45 to move downward until it contacts the surface of the alarm 46 on the inner wall of the monitoring box 42. When the alarm piece 45 contacts the alarm 46, the alarm 46 automatically sounds an alarm, indicating that the amount of water inside the treatment tank 104 is too low and that water needs to be added to the treatment tank 104 in time through the feed cylinder, so as to realize the function of the treatment device to monitor the amount of water inside the treatment tank 104.

[0031] Working Principle: In use, first place the device housing 1 in the designated position. The user introduces wastewater into the mixing tank 101 through the cylinder 102. The user operates the control button 103, which controls the rotating motor 114. The rotating motor 114 drives the agitator 113 to rotate inside the mixing tank 101. The agitator 113 then drives the scraper 112 to rotate inside the mixing tank 101, scraping off impurities adhering to the inner wall of the mixing tank 101. Subsequently, the wastewater enters the device housing 1 through the drain hole 111 and falls into the screening box 110, where impurities are filtered out. Then, the user operates the control button 103 again, which controls the first water pump 115 to operate. The first water pump 115 extracts the wastewater from the device housing 1 and then guides it into the nozzle water pipe assembly 122. Subsequently, the user introduces the treatment liquid into the treatment liquid tank 104 through the feed cylinder. The treatment liquid enters the nozzle water pipe assembly 122 and is then sprayed onto the wastewater and treatment liquid through the nozzle water pipe assembly 122, causing the wastewater and treatment liquid to enter the fixed tank 120. Under the action of the MBR flat membrane layer 121, the wastewater is filtered. Then, the user operates the control button 103 to control the second water pump 116 to work. Under the action of the second water pump 116, the water inside the fixed tank 120 is sucked out and introduced into the aeration tank 107. The user then operates the control button 103 to control the air pump 117 to work. Under the action of the air pump 117, gas is sucked into the aeration tank 107 to aerate the wastewater inside the aeration tank 107. Subsequently, the treated wastewater is discharged from the aeration tank 107 through the outlet pipe 119, and the gas is discharged under the action of the air outlet pipe 118 and the installation pipe 106.

[0032] Subsequently, the user operates the control button 103, which controls the electric push rod 233 inside the fixed cylinder 21 to work. Under the action of the electric push rod 233, the moving column 232 slides inside the guide groove 22. Under the action of the guide groove 22, the moving column 232 is guided. At this time, the moving column 232 drives the screening box 110 to slide inside the groove 231. Under the action of the groove 231, the moving position of the mixing box 101 is guided, avoiding the phenomenon of tilting when the screening box 110 moves. Thus, the garbage and impurities in the wastewater are screened inside the screening box 110, so as to realize the function of the treatment device for vibrating screening of wastewater. This greatly improves the treatment effect of the treatment device when it is used, and enables the treatment device to collect the impurities in the wastewater together.

[0033] Subsequently, the user needs to replace the MBR flat membrane 121 periodically. The user rotates the rotating plate 32 on the surface of the L-shaped frame 31, causing the rotating plate 32 to move the positioning clip 331 away from the inside of the positioning slot 332. Then, the user pulls the MBR flat membrane 121, causing it to move inside the fixed box 120. At this time, the MBR flat membrane 121 drives the connecting block 333 to slide inside the L-shaped frame 31. Under the action of the connecting block 333, the MBR flat membrane 121 is guided, thereby pulling the MBR flat membrane 121 out from the inside of the fixed box 120 for replacement and cleaning. This realizes the function of convenient replacement of the MBR flat membrane 121 in the treatment device, making it convenient for the user to pull the MBR flat membrane 121 out from the inside of the fixed box 120 during use, and to disassemble and clean the surface of the MBR flat membrane 121, resulting in better wastewater treatment effect of the treatment device.

[0034] Subsequently, as the amount of treatment liquid inside the treatment liquid tank 104 decreases, the float plate 41 moves downwards as the amount of treatment liquid inside the treatment liquid tank 104 decreases. At this time, the float plate 41 drives the float rod 43 to slide on the inner wall of the monitoring box 42. The float rod 43 slides inside the tank 44 and is guided by the tank 44. When the float rod 43 moves downwards, it drives the alarm piece 45 to move downwards until it contacts the surface of the alarm 46 on the inner wall of the monitoring box 42. When the alarm piece 45 contacts the alarm 46, the alarm 46 automatically sounds an alarm, indicating that the amount of water inside the treatment liquid tank 104 is too low and that water needs to be added to the treatment liquid tank 104 in a timely manner through the feed cylinder. This enables the treatment device to monitor the amount of water inside the treatment liquid tank 104, thus preventing the amount of water inside the treatment liquid tank 104 from becoming too low during the use of the treatment device, and finally completing the operation of the treatment device.
