MBR工艺处理印染废水的研究进展

纺织是高能耗、高污染行业,印染废水对我国环境影响巨大。近几十年,众多学者对印染废水的处理技术进行了大量研究。其中,膜生物反应器(MBR)由于占地面积小、出水水质好、污泥浓度高、污泥产率低等被用作处理印染废水的首选工艺之一。梳理了MBR工艺处理印染废水的研究文献,总结亟需解决的难题。

Advances in treatment of textile wastewater with membrane bioreactor

Textile country is a high energy consumption,high pollution industry,and textile wastewater has a huge impact on the environment.In recent decades,many scholars have done a lot of research on the treatment technology of textile wastewater.Membrane bioreactor(MBR)has been used as one of the pre?ferred processes for the treatment of printing and dyeing wastewater due to its small footprint,good effluent quality,high sludge concentration and low sludge yield.The research literature of MBR process for dyeing and dyeing wastewater treatment was reviewed,and the problems needed to be solved were summarized.
