染料废水处理方法研究进展

The progress of treatment methods of dye wastewater

随着染料工业的迅猛发展,导致染料废水的排放量日益增加,对环境的污染逐渐加重,对人体健康也构成了极大的危害。对物理法(活性炭吸附法、膜分离技术、磁分离技术)、化学法(电化学、化学氧化法)、生物法(真菌处理染料废水法、细菌处理染料废水)所使用的各种新材料、新工艺进行了综述,重点归纳了物理法和化学法,并提出当前染料废水处理过程中存在的主要问题及今后发展的趋势。

The rapid development of dyestuff industry increases the emissions of the dye wastewater,gradually aggravating thepollution in the environment and posing a great threat to the human health.So it is important to develop effective methods toclean the dye wastewater.Various new materials and new processes are involved in physical methods(the activated carbonadsorption method,the membrane separation technology,and the magnetic separation technology),chemical methods(theelectrochemical process,the chemical oxidation process)and biological methods(the dye wastewater treatment by fungi,the dyewastewater treatment by bacteria),as reviewed in this paper,focusing on the physical methods and the chemical methods.Themain problems in the process of the dye wastewater treatment and the development trend are put forward.
