活性炭固定床吸附硝基苯废水性能研究

Adsorption of nitrobenzene wastewater from solution in activated carbon fixed bed

利用活性炭固定床吸附硝基苯废水溶液,分析了活性炭填充量、硝基苯废水浓度和流量等因素对吸附效果的影响。结果表明,流量越低、活性炭用量越多、硝基苯废水浓度越低,越有利于吸附溶液中的硝基苯。利用Bed Depth Service Time(BDST)、Tomas、Admas-Bohart和Yoon-Nelson模型对硝基苯废水进行了吸附模拟,效果均较好。

The adsorption behavior of nitrobenzene wastewater solutions with fixed activated carbon bed was studied.The effect of various parameters like bed depths,concentration and flow rates of nitrobenzene wastewater were investigated.The results showed that the lower flow rate,more activated carbon amount and lower nitrobenzene concentration would benefit the adsorption effect.The adsorption data also fitted Bed Depth Service Time(BDST)、Tomas,Admas-Bohart and Yoon-Nelson models well.
