Efficient inclined plate oil removal and sand settlement apparatus

The invention discloses an efficient inclined plate oil removal and sand settlement apparatus. The apparatus includes a pool body and a sand hopper positioned below the pool body; the lower side surface of one end of the pool body is provided with a water inlet tube, and the lower side surface of the other end of the pool body is provided with a water outlet tube; the bottom of the sand hopper is provided with a sand outlet tube; a position close to the water inlet tube end in the pool body is provided with a water distribution weir, the water distribution weir comprises a body and through holes uniformly distributed on the body; a position close to the water outlet end in the pool body is provided with a water outlet weir; and a plurality of inclined plates formed through serial connection of vortex street columns distributed according to an Achimedean spiral are arranged between the water distribution weir and the water outlet weir, the length direction of the vortex street columns is vertical to the direction of flowing of water into the inclined plates from the water distribution weir, and the length direction o a gap formed by adjacent inclined plates parallels to the direction of flowing of water into the inclined plates from the water distribution weir. The apparatus has the advantages of fast and efficient sand-water separation, stripping of organic matter from the sand grains, gravity flow of an oil-containing supernatant through a water outlet device, and regular discharge of water and oil removed sand grains falling into the sand hopper.
