|1. (WO2018184391) METHOD FOR SYNCHRONOUSLY REMOVING COMPLEX HEAVY METAL AND ORGANIC SUBSTANCE BY MAGNETIC SEPARATION|
|Title:||METHOD FOR SYNCHRONOUSLY REMOVING COMPLEX HEAVY METAL AND ORGANIC SUBSTANCE BY MAGNETIC SEPARATION|
A method for synchronously removing a complex heavy metal and an organic substance from waste water with a magnetic iron-based material comprises four steps including an anaerobic reaction, an incubation reaction, an aerobic reaction, and a magnetic separation reaction. Reductive decomplexation of a complex heavy metal is achieved by utilizing the reducibility of an iron-based material under anaerobic conditions, and a catalyst having a function of activating molecular oxygen is formed in-situ simultaneously. Molecular oxygen is catalyzed by an iron-based catalyst under aerobic conditions to form a species with strong oxidizability, and an organic contaminant is oxidized and degraded. The removal of contaminants is enhanced through magnetic separation. The idea of treating waste with waste achieves eco-friendly oxidation, shortens treatment processes, improves treatment efficiency, reduces economic costs, and promotes the application of technology in industry.
