印染废水治理技术的进展

PROGRESS OF PRINTING-DYEING WASTEWATER TREATMENT

本文概括介绍了"七五"期间,我国在印染废水治理技术方面取得的新进展,它们均已通过中试或生产性验证。包括:厌氧-好氧生物处理系统、生物铁法、优良脱色菌和PVA 降解菌的筛选和应用、新型高效混凝剂、高压脉冲电解法等。上述方法对印染废水的处理效果均可达到 COD_(cr)去除70～90%、脱色70%以上,且经济合理、便于推广。

The new advances on print-dyeing wastewater treatment which have been verifiedby pilot plant or productive statements during the 7th national five years plan of the state were summarized in this paper.By methods of all kinds including anaerobic-aerobic biological treatment,bioferro method,screening and application of superiors decolorizable and PVA degradable bacteria,new high effective coagulants,high-voltage pulse electrolysis etc for print dyeing wastewater treatment,a COD removal to 70～90% and decolorizing over 70% has been gained.The methods are easy to promote becausethey are reasonable and economic.
