印染废水生物处理的研究现状及发展

Research status and development of biological treatment for printing and dyeing wastewater

长期以来,印染废水的脱色一直是印染废水处理过程中难以解决的问题,生物法作为低成本、无二次污染的污水处理技术在印染废水处理领域具有广泛应用。从菌种的筛选及培养、处理工艺的优化以及印染废水回用3个方面,对印染废水生物处理技术的研究现状进行了探讨。

The decoloration of printing and dyeing wastewater is always a difficult problem to solve in the treatment process of printing and dyeing wastewater. As a low cost and no secondary pollution wastewater treatment technology, biological method has been widely applied in the field of printing and dyeing wastewater treatment. The research status of biological treatment for printing and dyeing wastewater is discussed from the screening and cultivation of strains, optimization of treatment process and reuse of printing and dyeing wastewater.
