[0052] The specific implementation method of a mineral wastewater treatment device provided in this embodiment is as follows:

[0053] S1. Wastewater feeding and removal of strip-shaped impurities: Start multiple rotating motors 103. The rotating motors 103 drive the hook drum 104 and the two scraping drums 105 to rotate. Then, the wastewater is discharged through the liquid inlet funnel 101. The wastewater falls through the hook drum 104. The hook drum 104 rotates to hook the strip-shaped sundries in the wastewater. Then, the two scraping drums 105 on both sides rotate to scrape the strip-shaped sundries on the hooks, and then turn over to pat the strip-shaped sundries onto the slag discharge inclined opening 106. The preliminarily filtered wastewater enters the solid-liquid separation tank 2 through the liquid outlet funnel 107.

[0054] S2. Solid-liquid separation of wastewater: The wastewater is discharged into the feed buffer tank 207 through the liquid outlet funnel 107 for buffering, and then flows into the space between the S-shaped solid-liquid separation filter plate 203 and the baffle 202 through the multiple discharge slots 208 and the guide plate 209 on the feed buffer tank 207. When the solution in the wastewater passes through the S-shaped solid-liquid separation filter plate 203 and filters into the liquid discharge funnel 205, the solid impurities in the wastewater continue to remain on the baffle 202. When the solid impurities accumulate to the specified capacity, the solid impurities press the S-shaped solid-liquid separation filter plate 203 to bend downward, and then the solid impurities flow into the fluid discharge inclined funnel 204 through the extrusion gap, and then the S-shaped solid-liquid separation filter plate 203 returns upward.

[0055] S3. Dewatering of water-containing sludge: The water-containing sludge impurities and the like flow into the separation barrel 401 through the fluid discharge inclined funnel 204. Start the centrifugal motor 405. The centrifugal motor 405 drives the centrifugal main shaft 409 to rotate through the belt drive assembly 404. The centrifugal main shaft 409 drives the separation barrel 401 to rotate at a high speed through the cross 406 for centrifugal operation. The liquid in the water-containing sludge impurities is discharged through the centrifugal operation, and then the discharged liquid enters multiple filter mesh tanks 505 through the connecting liquid discharge pipe 403 for fine filtration, and the filtered solution is discharged through the total discharge pipe 503.

[0056] S4. Secondary refinement filtration of the filtered solution; the filtered solution flows into the liquid spraying pipe 708 through the liquid feeding funnel 205. Start the fine filtration motor 701. The fine filtration motor 701 drives the fine filtration drum 707 to rotate through gear transmission. The liquid spraying pipe 708 sprays the filtered solution, which is then subjected to secondary refinement filtration by the fine filtration drum 707. The solution after refinement filtration falls into the collection funnel 705 and is then discharged through the main liquid discharge pipe 704.

[0057] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
