研究了活性炭固定床对水中苯酚的动态吸附特性及影响因素。结果表明,活性炭对苯酚废水的动态吸附随进水苯酚含量和流量的增大穿透时间缩短,但最大设计体积流量不能超过6.47 m L/min;随固定床高度增加,穿透时间推迟,但最小设计高度不能小...研究了活性炭固定床对水中苯酚的动态吸附特性及影响因素。结果表明,活性炭对苯酚废水的动态吸附随进水苯酚含量和流量的增大穿透时间缩短,但最大设计体积流量不能超过6.47 m L/min;随固定床高度增加,穿透时间推迟,但最小设计高度不能小于8 cm。无效层厚度随进水流量和固定床高度的增加而增大,随进水苯酚含量增大而减少。经拟合发现实验结果更符合Yoon-Nelson模型,且相关系数都在0.9以上。展开更多
