摘要
印染废水由于其水质特点一直是废水治理的难点和重点。本文利用盐酸对一种粘土物质进行改性得到了一种新型吸附剂,并对模拟印染废水试验研究进行了探讨。试验结果表明,废水的脱色率可达99%以上,COD去除率也可达到67%左右。
The prmting and dyeing wastewater which has high chromaticity and rich inorganic substances, is more difficult to treatment. In this study, a new adsorbent was produced by modified one kinds of clay through hydrochloric acid. This adsorbent was used to trcat the simulative printing and dyeing wastewater, the results showed thai the maximum decolorization ratio was over 99 % and the maximum removal ratio of COD was about 67 %.
