A review on treatment methods of dye wastewater

The current research status and progress of treatment methods for dye wastewater were reviewed.The treatment methods for dye wastewater mainly included:physical method(adsorption,membrane separation,and magnetic separation),chemical method(electrochemical process,photochemical and photocatalytic oxidation,Fenton and Fenton-like oxidation and ozone oxidation),biological method(anaerobic method,aerobic method,anaerobic-aerobic combination process).The kinds of new materials and new technology were summarized.The problems existing in the field of dye wastewater treatment were analyzed.Aiming at the problems,the development trends were prospected.
