[0021] In this embodiment: The wastewater is injected into the collection tank for collection. The wastewater in the collection tank is injected into the acid-base neutralization tank, and the pH of the wastewater is monitored. The pH value of the wastewater is adjusted by adding alkali or acid; the adjusted wastewater is injected into the flocculation and sedimentation device, and then a flocculant is injected. The generated sediment is put into a sludge processor for treatment. The wastewater is treated through a heavy metal catcher, a photocatalytic reactor, a micro-electrolysis reactor and a microbial reactor, and then deeply treated through a biological active adsorption device, a precision filter and a PVDF membrane to reach the discharge standard.

[0022] Please pay special attention to Figures 2 to 6, the filtering mechanism 7 includes a mounting plate 701 which is fixedly connected to the top of the flocculation sedimentation tank 1 and is located on one side of the feed inlet 6. A motor 702 is installed on the top of the mounting plate 701. The output end of the motor 702 is connected to a first threaded rod 703. An activity plate 704 is slidably connected to the outer wall of the first threaded rod 703. An activity tube 705 is fixedly connected to the outer wall of the activity plate 704. The activity tube 705 is slidably sleeved on the outer wall of the extraction tube 4. A connecting frame 706 is fixedly connected to the bottom outer wall of the activity tube 705. A first mounting frame 707 is fixedly connected to the bottom end of the connecting frame 706. A second mounting frame 708 is rotatably connected to one side of the first mounting frame 707. The second mounting frame 708 is located below the feed inlet 6. A first filter plate 709 is fixedly connected to the inner wall of the first mounting frame 707.

[0023] In this embodiment: When the motor 702 operates, it drives the first threaded rod 703 to rotate. The rotation of the first threaded rod 703 drives the activity plate 704 to displace. The displacement of the activity plate 704 drives the activity tube 705 to displace. At this time, the activity tube 705 slides along the outer wall of the extraction tube 4. The displacement of the activity tube 705 drives the first mounting frame 707 to perform a displacement operation through the connecting frame 706. When the connecting frame 706 moves upward to drive the first mounting frame 707 to move upward, at this time, the extrusion block 716 first contacts the top inner wall of the flocculation sedimentation tank 1, pushing the extrusion block 716 to displace. The displacement of the extrusion block 716 pushes the block 714 to displace. The displacement of the block 714 enters the rack 712 and separates from the connecting frame 706, squeezing the second spring 715, so that the rack 712 can displace downward relative to the connecting frame 706. Then the rack 712 contacts the top inner wall of the flocculation sedimentation tank 1, pushing the rack 712 to displace, squeezing the first spring 713. The displacement of the rack 712 drives the first spur gear 711 to rotate. The rotation of the first spur gear 711 drives the second mounting frame 708 to rotate. The second mounting frame 708 rotates to a vertical state and moves away from below the feed inlet 6. At this time, wastewater and flocculant can be injected into the flocculation sedimentation tank 1 through the feed inlet 6. When the connecting frame 706 moves downward, at this time the rack 712 is separated from the flocculation sedimentation tank 1, and the rack 712 is displaced and reset under the elastic force of the first spring 713. The displacement of the rack 712 drives the first spur gear 711 to rotate. The rotation of the first spur gear 711 drives the second mounting frame 708 to rotate horizontally. At this time, the latch 714 is displaced to the top of the connecting frame 706. The latch 714 is displaced and contacts the top of the connecting frame 706 under the elastic force of the second spring 715 to position the rack 712. The first mounting frame 707 and the second mounting frame 708 move downward, and the first filter plate 709 and the second filter plate 710 filter the wastewater. The liquid pump 5 is started, and the extraction pipe 4 pumps water through the movable pipe 705. The filtered wastewater is extracted by the extraction pipe 4 through the movable pipe 705. The sediment is always located below the first mounting frame 707 and the second mounting frame 708, which is convenient for preventing the sediment from being extracted by the pipeline.
