Reaserch Development on Removal Technology of Organic Pollutant in Reverse Osmosis Concentrate

The disposal and treatment of reverse osmosis concentrate was an urgent problem because of increasingly stringent requirement of the wastewater management and discharge standards.The principle and effectiveness of flocculation and sedimentation,adsorption of activated carbon,Fenton oxidation,ozone oxidation,photocatalytic oxidation,electrochemical oxidation,chlorine dioxide three phase catalytic oxidation and ultrasonic oxidation were summerized in this paper.The advantages and disadvantages of different technologies were compared and the future research on treatment of organic pollutant in reverse osmosis concentrate was discussed.
