Intelligent graded recycling treatment system for mixed wastewater in mine

The invention discloses an intelligent graded recycling treatment system for mixed wastewater in a mine. The intelligent graded recycling treatment system comprises a water collecting tank for collecting wastewater, wherein the wastewater in the water collecting tank is conveyed to primary solid-liquid separation equipment for water inlet separation; the wastewater separated by the primary solid-liquid separation equipment is conveyed to a radial-flow sedimentation tank; upper-layer clear water settled by the radial-flow sedimentation tank overflows to a clear water pond for later use; sludge settled by the radial-flow sedimentation tank is conveyed to a sludge pond; sludge in the sludge pond is conveyed to a diaphragm filter press; a filter plate on the diaphragm filter press communicates with a compressed gas device through a squeezing hose; mud cakes discharged by a discharge hopper below the diaphragm filter press are carried away through a forklift and a vehicle; and filter pressing water of the diaphrag
