Abstract: This paper introduced the hazard, source and characteristics of dyeing and printing wastewater, and analysed the reason of the bio-chemical treatment without effect; reviewed the treatment from physical chemistry, chemistry, biology and a combination of different approaches comprehensively; summed up the current approaches applied broadly, among them adsorption and coagulation were applied in further disposal and recycling universally, advanced oxidation technology and its combination were researched broadly, anaerobic and aerobic treatments and their combination were the main approaches to dispose CODCr and color; stressed an introduction to advanced oxidation and biological technique and their advantages, problems and the major research topics at present; summed up the research aspects currently; put forward that the combination of different methods to treat the dyeing and printing wastewater should be applied in large; and advocated clean production of source reduction and process control in dyeing and printing industry.
Key words: environmental engineering; dyeing wastewater; review; advanced oxidation; biological treatment; adsorption; coagulation
