摘　　要：沤麻过程中产生的废水量大,浓度高,气味难闻,含有大量不易降解的单宁、木质素。研究采用气浮/粉煤灰/土壤渗滤系统处理沤麻废水,结果证明,该处理系统取得了良好的效果。COD去除率为95%~98%,木质素去除率为80%~89%,处理后的出水可回用于沤麻,有很好的经济效益和环境效益。In the process of retting flax,there is a large quantity of wastewater with bad smell and high concentrated organic substances.In this paper study on air flotation/fly/soil-percolation of treating retting flax water has been conducted.The results show that the retting flax wastewater can be well treated by air flotation/fly/soil-percolation.The maximum removal rate of CODcr,lignin is 95%～98% and 80%～89% respectively.The treated wastewater can be reused to ret flax,so that the obvious economic and environmental benefits can be achieved.
