摘　　要： 分别从生物处理法、化学氧化法、吸附法和电化学法等方面介绍了印染废水的处理方法和研究进展,介绍了放电等离子体技术、超临界水氧化技术、膜分离技术以及超声波技术等新兴的治污技术,分析了染料废水处理技术的研究状况。化学氧化技术使用广泛,一般常用于生物处理的前处理;吸附法的吸附效率较高,吸附过程不破坏染料的分子结构,染料可以回收利用;电化学技术不仅能去除重金属,而且能去除化学需氧量(COD)、生物需氧量(BOD)和总悬浮固体(TSS)浓度,对染料的脱色效果很好;超临界水氧化法使有毒有害的有机物完全转化,可以避免二次污染问题,氧化反应速率快,适用范围广;膜分离技术高效、节能,可实现废水的循环利用和有用物质回收;超声技术操作条件温和、降解速率快、可以单独使用或与其他水处理技术联合使用。 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.
