Abstract

A water reclamation method on the basis of integrated use of magnetic resin adsorption and electrosorption is provided. It belongs to the water reclamation field, including the following steps: pump the biotreated effluent into a reactor that is filled with magnetic resin particles so that the chromaticity, organic pollutants, total nitrogen, total phosphorus contained in the wastewater can be effectively reduced; channel the fully reacted mixture into a precipitation tank for separation; part of the separated magnetic resin is pumped back into the reactor while the rest of the separated magnetic resin flows into a regeneration tank; the wastewater treated by magnetic resin adsorption then flows into an electrosorption unit for a desalting process; the remaining organic pollutants and inorganic pollutants are further removed.
