  • Method for simultaneous removal of heavy metals and organic matters from wastewater
    Patent number: 11117822
    Abstract: The present invention relates to a method for simultaneous removal of heavy metals and organic matters from wastewater, including four steps: anoxic reaction, incubation reaction, aerobic reaction and sedimentation reaction, to solve tricky problems and shortcomings of current treatment technologies for industrial wastewater containing both heavy metals and organic substances. Compared with current technologies, in the present invention, by regulating and controlling heavy metal ions in wastewater, catalysts with function of activating molecular oxygen are in-situ generated, catalyzing dioxygen to produce strong oxidative species, thereby realizing catalytic oxidation of organic pollutants and crystallization and precipitation removal of heavy metals, which creatively treats waste using waste to achieve green oxidation, shortened treatment process, improvement of treating efficiency, reduction of economic cost and promotion of technology for industrial application.
