摘要: 本文采用高温氧气流改性和再生天然海泡石,研究了改性海泡石(H/海泡石)吸附去除模拟印染废水中碱性嫩黄O染料及其再生的性能,以及H/海泡石静态吸附碱性嫩黄O的特点,采用相关模型拟合,考察了高径比(填料高度与吸附柱内径的比值)、染料溶液流速和浓度对H/海泡石动态吸附的影响。结果表明,改性温度和时间分别为550 ℃和1 h,氧气流速为6 L/min得到的改性海泡石的单位吸附量超过200 mg/g;Langmuir等温吸附方程、准一级动力学方程分别符合H/海泡石的吸附行为、吸附动力学;高径比为2.5,染料流速为每小时6倍床体积,染料初始浓度为200 mg/L时,H/海泡石分别能处理的废水量约为55、42和45倍床体积;采用高温氧气流对吸附饱和的H/海泡石进行再生,再生温度和时间分别为550 ℃和20 min,再生氧气流速为6 L/min时,再生率接近100%。
