▎ 摘  要

NOVELTY - A new, simple and inexpensive fluidized capacitive deionization (FdCDI) method and device for recycling of rare precious metals (RPMs) and water from inorganic wastewater is described in this invention. The engineering concept, process simplification, and automatic operation of the FdCDI process are much better than the existing wastewater treatments that discharge excess sludge. Since no chemical agent is used, no sludge is yielded, and the FdCDI can be considered a green process for recycling of RPMs as well as water. The FCDI device is designed with modularization and automation, and thus, the treatment capacities can be flexibly increased as needed with a low maintenance frequency and high efficiency operation. In addition, nanoreactor-type photocatalysts can also be used in the FdCDI process for photodegradation of organic pollutants for better water recycling and reuse.
