[0034] The specific implementation method of a mineral wastewater treatment device provided in this embodiment is as follows: S1. Wastewater feeding and removal of strip-shaped impurities: Start multiple rotating motors 103. The rotating motors 103 drive the hook drum 104 and two scraping drums 105 to rotate. Then, discharge the wastewater through the liquid inlet funnel 101. The wastewater falls through the hook drum 104. The hook drum 104 rotates to hook the strip-shaped impurities in the wastewater. Then, the two scraping drums 105 on both sides rotate to scrape the strip-shaped impurities on the hooks. Then, turn over to slap the strip-shaped impurities onto the slag discharge inclined opening 106. The preliminarily filtered wastewater enters the solid-liquid separation tank 2 through the liquid outlet funnel 107. S2. Solid-liquid separation of wastewater: Discharge the wastewater into the feed buffer tank 207 through the liquid outlet funnel 107 for buffering. Then, flow through multiple discharge slots 208 and the guide plate 209 on the feed buffer tank 207 into the space between the S-shaped solid-liquid separation filter plate 203 and the baffle 202. When the solution in the wastewater filters through the S-shaped solid-liquid separation filter plate 203 and flows 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. Then, the solid impurities flow into the fluid discharge inclined funnel 204 through the extrusion gap. Then, the S-shaped solid-liquid separation filter plate 203 returns upward. S3. Dewatering of water-containing sludge: Flow the water-containing sludge impurities and the like 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 the centrifugal process. Discharge the liquid in the water-containing sludge impurities through the centrifugal process. Then, the discharged liquid enters multiple filter mesh tanks 505 through the connecting liquid discharge pipe 403 for fine filtration. The filtered solution is discharged through the total discharge pipe 503. S4.
