After the precipitation is generated, control the start of the second motor 363. Under the action of the second motor 363, the conveyor belt 365 rotates on the surfaces of the driving pulley 364 and the driven pulley 366. When the conveyor belt 365 moves, the positioning block 368 makes the sliding piece 369 drive the folding filter screen 3610 to perform a folding action, so that the folding filter screen 3610 is laid flat above the rectangular frame 361, so that the precipitated impurities are located below the folding filter screen 3610 to form an obstruction above the precipitate. Then, the servo motor 384 can be controlled to start. Under the action of the servo motor 384, the screw 385 rotates inside the internal thread block 386. When the screw 385 rotates, through the cooperation with the internal thread block 386, the displacement block 387 drives the inner cylinder 382 to change its position inside the outer cylinder 381, so that the height of the bottom position of the inner cylinder 382 is adjusted and changed to adjust to different height positions to suck the wastewater, reducing the sucking of the precipitated impurities. And the drive motor 3882 can be periodically started. Through the cooperation of the main gear 3883 and the gear ring 3885, the gear ring 3885 rotates inside the cushion rack 3884, so that the gear ring 3885 drives the scraping rod 3886 to rotate to clean the circular mesh sheet at the bottom side of the inner cylinder 382;

[0052] Fourth, send the wastewater sucked out by the inner cylinder 382 and the outer cylinder 381 into the multi-stage reactor 4, and in this reactor, a chemical reaction is realized by adding lime medicament to reduce the copper sulfate concentration in the wastewater;

[0053] Fifth, introduce the treated wastewater from the multi-stage reactor 4 into the nanomaterial adsorption tank 5, and use the nanomaterials to adsorb and remove harmful substances in the wastewater;

[0054] Sixth, introduce the effluent from the nanomaterial adsorption tank 5 into the bioreactor, and use the microorganisms in the bioreactor to further degrade the harmful substances in the water;

[0055] Seventh, finally, subject the effluent from the bioreactor to natural treatment through an artificial wetland, and absorb and transform the residual harmful substances in the wastewater through the roots of plants, thereby achieving the purification of the wastewater.

[0056] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
