摘要
印染废水是一种有机物含量高、色度高、生化性能差的难降解有机废水,本文结合我国印染行业及其废水处理技术实际情况,综合讨论了目前印染废水处理技术中COD难以降低和高色度废水难以脱色的两大难点。
Printing and dyeing wastewater is one kind of nondegradable wastewater with high content of organic matters, high colority and poor biochemical performance. Based on the present status of the printing and dyeing industry and the wastewater treatment technology in our country, the paper discusses two difficult points which exist in the treantment technology at present, first, the COD is hard to be removed; second, the high colority wastewater is difficult to be decoloured.
