Compared with the traditional sludge sand setting technology, the invention has the following beneficial effects:
1. the sand setting device designed by the invention needs to wait because the silt is deposited by gravity, and is the same as the traditional advection sand setting device, but the sand setting device designed by the invention adopts the shielding piece for separation, so that the silt and the precipitated sewage can be simultaneously sucked in the suction process, and the efficiency of the equipment is improved.
