Abstract：The research progress of printing and dyeing wastewater treatment methods is reviewed in this paper, which include the biological treatment method, chemical oxidation method, adsorption method and electrochemical method. The new wastewater treatment technology such as the discharge plasma technology, supercritical water oxidation technology, membrane separation technology and ultrasound technology are discussed. The dye wastewater treatment technology is specially addressed. Chemical oxidation technique is widely used and usually as a pretreatment before biological treatments. Adsorption technique is efficient and does not destroy the structure of dye molecules, while the dye can be recycled. Electrochemical techniques not only can remove heavy metal ions, but also can remove Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) and Total Suspended Solids (TSS), with a good effect on the decolorizing dye. Supercritical water oxidation can completely discolor noxious organics so as to avoid the secondary pollution, with a fast reaction rate and a wide application. Membrane separation technique is efficient and energy saving, which reuses waste water and recycles useful substance. Ultrasonic technique has a fast reaction rate and can be used in various operating conditions. It not only can be used alone but also be combined with other methods.
