[0043] Specifically, when it is necessary to adjust the position of the honeycomb collection block 307, the limiting block 306 is removed from the limiting groove 305, the long strip slider 301 is manually lifted, since the guide gear 304 is meshed with the rack 303 fixed to the outer wall of the long strip slider 301, the movement of the rack 303 drives the rotation of the corresponding guide gear 304, under the synergistic action of the plurality of guide gears 304 and the racks 303, the long strip slider 301 obtains power for moving along the direction of the sliding groove 302, the friction between the long strip slider 301 and the sliding groove 302 is reduced, the sliding groove 302 provides a moving track for the long strip slider 301 and guarantees the accuracy of the moving direction of the long strip slider 301, when the long strip slider 301 moves, the corresponding honeycomb collection block 307 moves synchronously with the slider, by controlling the moving distance and direction of the long strip slider 301, the depth of the position of the honeycomb collection block 307 in the water collecting pool 2 can be adjusted, when the honeycomb collection block 307 moves to a suitable water level environment, the position of the long strip slider 301 is fixed through the cooperation of the limiting block 306 and the limiting groove 305, so as to limit the movement of the long strip slider 301, so that the honeycomb collection block 307 stably stays at the position, at this time, the honeycomb collection block 307 provides a stable living environment for the microorganisms inside, the microorganisms utilize the sewage in the water collecting pool 2 to carry out denitrification and phosphorus removal metabolic activities under the suitable water level conditions.

[0045] Specifically, when installing the device, the user can connect the device with a specific mobile device through wireless technology, so that the user can not only remotely control but also control the device through the control panel 23. The fixed column 17 supports the sunshade plate 18 to form a protective space. The sunshade plate 18 can block direct sunlight to prevent internal parts from aging due to exposure to the sun, and can also block rainwater from eroding electronic components. The worker can check the situation around the device in real time through the monitor 21. Once an abnormal situation is found, the alarm 22 sends an audible and light alarm to remind people around to pay attention so as to timely handle the problem. When the light is insufficient, the worker turns on the illuminating lamp 20 on the lamp holder 19 to provide lighting for the on-site operation, which is convenient for equipment inspection, maintenance or parameter adjustment. The protective shell 24 can protect the control panel 23 from dust and rainwater to affect the normal use of the control panel 23. When installing the filter screen 6, the end of the filter screen 6 with the magnetic strip two 26 is aligned with the magnetic strip one 25 in the mounting groove 5. The filter screen 6 is stably installed in the mounting groove 5 by using the principle of magnetic attraction, avoiding displacement or falling of the filter screen 6 due to water flow impact. If the flora in the honeycomb assembly block 307 needs to be adjusted, the operator rotates the honeycomb assembly block 307, and uses the threaded connection between the threaded column 309 and the threaded groove 308 to detach the honeycomb assembly block 307 from the long strip sliding block 301, which speeds up the operation.

[0046] Working principle: when the water flows through the water collecting pipe 4, the filter screen 6 in the installation groove 5 intercepts the water flow, because the mesh size of the filter screen 6 is smaller than the size of the impurity particles, so that the impurities in the water flow are intercepted on the left side of the filter screen 6, reducing the impurity content entering the water collecting tank 2, reducing the interference of impurities on the microbial treatment process, when the impurities on the left side of the filter screen 6 accumulate to a certain extent, the servo motor 7 at the top end of the water collecting tank 2 is started, the gear one 8 is driven to rotate, and through the meshing connection between the gear one 8, the chain 10 and the gear two 9, the gear two 9 and the rotating shaft 11 are driven to rotate, and the limiting column 12 avoids the left and right movement of the rotating shaft 11, prevents the chain 10 from falling due to the movement of the rotating shaft 11, and when the rotating shaft 11 rotates, the cleaning brush 13 also rotates synchronously, so that the cleaning brush 13 brushes off the impurities attached to the filter screen 6 from the filter screen 6, and the elastic scraper 14 has a certain elasticity, when the elastic scraper 14 rotates through the bottom of the inner wall of the water collecting pipe 4, the sludge accumulated on the bottom of the inner wall of the water collecting pipe 4 and brushed off by the cleaning brush 13 is scraped, so that the sludge moves to the direction of the drainage channel 15, and finally is guided to the collecting groove 16 opened at the top of the front side of the planting field 1, facilitating subsequent unified treatment of the sludge.

[0047] And when it is necessary to adjust the position of the honeycomb assembly block 307, first remove the limiting block 306 from the limiting groove 305 to release the position limitation of the long strip sliding block 301, at this time manually lift the long strip sliding block 301, and the meshing connection relationship between the plurality of guide gears 304 and the rack 303 assists the sliding of the sliding block in the direction of the sliding groove 302, which not only reduces the difficulty of manual operation, but also replaces the sliding friction between the sliding block and the sliding groove 302 with gear rolling friction, greatly reducing the movement resistance. The sliding groove 302 serves as a fixed track for the long strip sliding block 301, and cooperates with the lateral restraint of the limiting groove 305 and the limiting block 306 to keep the honeycomb assembly block 307 stable during movement and accurately correspond to different depth environment areas in the water collecting tank 2. The cooperation of the limiting block 306 and the limiting groove 305 enables the long strip sliding block 301 to be fixed at the appropriate position, so that the honeycomb assembly block 307 creates a stable survival environment for the internal microorganisms, enabling the microorganisms to carry out targeted denitrification and phosphorus removal metabolism, and finally achieving the strengthened purification of farmland drainage.
