Abstract:

Advanced redox technologies are the key method toward refractory industrial wastewater remediation. The wildly utilized micro-electrolysis, Fenton fluidized bed, and catalytic ozone usually apply centimeter-scale catalytic materials and fixed-bed modes, which suffer from technical bottlenecks such as low mass transfer efficiency, easy scaling and passivation, low catalytic efficiency, poor precise oxidation ability, and weak sustained catalytic ability. While the extremely high cost and reuse difficulty of nanomaterials in fundamental research also limit their practical applications. In response to these problems, by exploring the interaction mechanism between reactive oxygen species and the molecular structure of pollutants, the speaker established novel methods to regulate the reactive oxygen species and thereby enhance the precise oxidation of pollutants. He also proposed a new theory that the near-free Fe(III) accelerates Fe(II) regeneration. He also created cost-effective micron-sized heavy particles, and develop supporting hydro-cyclone technology and equipment to enhance mass transfer in refractory industrial wastewater treatment.
