Wastewater of dyeing industry has complicated constituents, and usually contains many kinds of dyes. It has deep tinct and strong toxicity, and it is difficult to decompose it. Its pH value fluctuates widely, and it has high concentration and large water quantity.The development status of the dyeing wastewater treatment inside and outside China is introduced, and the physics method, chemical method, physical chemistry method and biological method are stated in detail. The applicable conditions and treating effect of the four methods are listed and the advantages and disadvantages are concluded.
