摘　　要：本文在传统铁屑内电解的基础上,提出了氧化絮凝复合床的新技术,并用该技术对印染废水进行处理,研究 pH值、反应时间等工艺参数的影响。研究结果表明,在酸性条件下(pH为 6 左右),停留时间 30—45分钟,处理效果基本稳定。CODcr的去除率可达 30%—95%,色度去除率均可达 95%以上,且可提高废水的可生化性,为后续生化处理创造了有利条件。On the basic of the principle and reaction mechanism of iron chip inner-electrolysis, the treatment of different dyeing wastewater with OFR is discussed. The results show that the pH value is about 6, the retention time is 30-45mins, the removal rate of chromaticity and CODcr are above 95% and 30%—90%, respectively . As for the practice application, oxide-flocculation shows many advantages, such as simple equipment, low operation cost, easy control, good effect and high biodegradability.
