System and method for wastewater treatment

摘要

The present disclosure is directed towards systems and methods for the treatment of wastewater. A system in accordance with one particular embodiment may include a front end system including at least one resin tank configured to contain an ion exchange resin configured to target a particular metal. The at least one resin tank may be configured to receive an output from an oxidation reactor configured to receive a flow of wastewater from a wastewater producing process. The system may further include a central processing system configured to receive a saturated resin tank from the at least one resin tank. The central processing system may further include a vacuum filter band system configured to receive a slurry from the saturated resin tank and to provide a cascading resin rinse to the slurry. The central processing system may further include a repetitive stripping system configured to receive a metal-filled purification unit from a metal specific purification system. The repetitive stripping system may be further configured to sequentially apply the contents of a plurality of acid tanks to the metal-filled purification unit to generate a metal salt. Numerous other embodiments are also within the scope of the present disclosure.

1. A method for treating wastewater comprising:
providing a front end system including at least one resin tank having an ion exchange resin configured to target a particular metal, receiving, at the at least one resin tank, an output from an oxidation reactor configured to receive a flow of wastewater from a wastewater producing process; receiving, at a central processing system, a saturated resin tank from the at least one resin tank, the saturated resin tank including the output from the oxidation reactor; fluidizing contents of the saturated resin tank including the output from the oxidation reactor, generating a slurry; receiving the slurry from the saturated resin tank at a vacuum filter band system; providing a cascading resin rinse to the slurry at the vacuum filter band system, generating a metal solution, wherein the cascading resin rinse includes a water rinse and an acidic wash; generating a metal-filled purification unit at a metal specific purification system by allowing the metal solution to flow through a plurality of purification units, wherein the metal specific purification system includes the plurality of purification units; receiving, at a repetitive stripping system, the metal-filled purification unit from the metal specific purification system to process the metal solution received from the vacuum filter band system; and sequentially applying, at the repetitive stripping system, contents of a plurality of acid tanks to the metal-filled purification unit to generate a metal salt solution from the metal solution, wherein the repetitive stripping system includes the plurality of acid tanks.
