Sewage desanding integrated system

The utility model discloses a sewage desanding integrated system, which belongs to the technical field of sewage treatment and comprises a lifting pump arranged at the bottom of a lifting tank. One end of a water outlet of the cyclone desander is obliquely arranged upwards; a water inlet of the cyclone desander is communicated with the lifting pump through a pipeline, so that sewage enters the cyclone desander along the tangential direction of the cyclone desander; the sand cylinder is arranged at the bottom of the cyclone desander and is communicated with a sand discharge port of the cyclone desander; and the sand-water separator is arranged below the sand cylinder and is communicated with the sand cylinder through a straight pipe. The cyclone desander is inclined by a certain angle, so that the problem that sand deposition is easily caused in a pipeline with a 90-degree elbow is solved; and civil engineering and pit digging are not needed, after the cyclone desanders are obliquely arranged, the cyclone desa
