The present invention relates the field of reclaimed water preparation. Disclosed is a reclaimed water treatment method based on magnetic resin adsorption coupled with electrosorption. Steps of the method are: a biochemical wastewater effluent is pumped into a reactor added with magnetic resin particles to effectively reduce the chromaticity, organic substances, total nitrogen, and total phosphorus in the wastewater; the wastewater that is fully mixed and adsorbed is precipitated in a sedimentation tank, the magnetic resin precipitated is partly returned and partly transferred to a reclamation pool, the wastewater adsorbed by the magnetic resin is introduced into an electrosorption apparatus, the wastewater is desalinated, and traces of organic substances and inorganic impurities in the water are further reduced. Indicators such as organic substance content, chromaticity, total nitrogen, total phosphorus, and total salts in water are significantly reduced after advanced treatment with the integrated technique of the present invention. The present invention not only effectively reduces the contents of organic substances, chromaticity, and total salts in wastewater, but also allows an electrosorption electrode to be provided with further extended service life, and provides a highly efficient and economical preparation method for high quality reclaimed water. |
