Abstract:
This invention discloses a kind of method to remove organic pollutants through coupling microwave degradation based on microporous mineral adsorption. It consists of the following major steps: Fill hydrophobic porous mineral adsorbent into the adsorption column to adsorb organic pollutants in the organic wastewater, and start up the microwave generator after the adsorbent reaches saturation so that the organic pollutants adsorbed inside the adsorption column can be degraded under microwave induction. With the alternative operation and regeneration of two adsorption columns, the organic wastewater can be treated continuously. In the invention, with the technologies of microwave-induced degradation through hydrophobic microporous mineral coupling adsorption, organic pollutants can be removed from water efficiently, and the degradation process and carrier can be circulated. The pollutants can be mineralized into non-toxic and harmless micromolecular substance completely.
