Abstract

A high salinity wastewater treatment system is provided according to the present application, which includes a hydrogel loading system and a flow-storage different-oriented-inlet-and-outlet system. The hydrogel loading system includes six separation plates, a wastewater treatment area, a water distribution bin, a rotating shaft, a driving motor and a fixed bracket. The six separation plates evenly separate the wastewater treatment area into six separate treatment sectors in an axial direction. The six separate treatment sectors are filled with hydrogel materials with water purification effect. The high salinity wastewater infiltrates into each separate treatment sector one by one through high salinity wastewater inlet meshes on a surface of the wastewater treatment area, and the purified high salinity wastewater is discharged through a wastewater cleaning outlet pipe with a same water inlet direction as a cleaning filler distribution pipe.
