| 摘 要： | 印染废水水质变化大、色度高,直接生物处理难度大,单一生化处理工艺难以达到排放要求.采用铁屑内电解-生化工艺对浙江某印染厂废水处理系统进行改进,内电解预处理大大提高了废水的可生化性,最终生化段出水CODCr去除率达到90%,色度去除率达到95%以上.铁屑内电解-生化工艺具有处理效果好、出水水质稳定、设备简单、操作管理方便、能耗低等特点,是处理印染废水的有效方法之一.

| Abstract: | Water quality of printing and dyeing wastewater changes quickly,with high colority and difficult to be degraded only by bio-treatment.The iron chip internal electrolysis-biochemical(ICIEB)process has been used to improve the former process of dyeing wastewater treatment.The biodegradability is improved markedly after pretreated by iron chip internal electrolysis process.The removal efficiency of CODCr and colority can reached 90% and 95%,respectively.The experiment demonstrates that the ICIEB process,with its high efficiency,stable water quality of effluent,easy operation and management and low energy consumption,has made it become one of the effective methods for dyeing wastewater treatment. |
