膜分离处理印染废水研究进展

印染废水具有水量大、色度高、成分复杂、环境污染严重等特点。膜分离技术处理印染废水具有选择性好、生产效率高和处理成本低等特点。基于对近年来的文献调研,综述了膜分离技术在印染废水处理中的研究进展情况,指出了膜分离法处理印染废水还存在的主要问题和未来发展方向,并对膜分离技术处理印染废水应用前景作了展望。

Dyeing Effluent Treatment by Membrane Separation

Dyeing effluents from textile industry are large volumes of heavily pollutive wastewaters with high colourity,containing complicated components.For the treatment of dyeing effluents,membrane filtration is more highly selective, productive and cost-effective than other techniques in view of the reclamation and recycling of the water,residual dyes and useful chemicals as well as the energies.Base on a survey on the articles published in the past a few decades,recent progresses in the dyeing effluent treatment by membrane separation were reviewed.The existing problems and the future tendency for membrane treatment of dyeing effluent were also presented.
