摘　　要：实验考察了活性炭在固定床、流化床和序批式反应器中吸附去除双酚A(BPA)的吸附规律和吸附容量利用效率。结果表明,对于固定床来说,进水流速越小、填充高度越高时,活性炭对双酚A的吸附去除效果更好,活性炭的利用率也更高。对于流化床,在总投加量一定的情况下,采用分次添加,可以进一步提高流化床中活性炭的容量利用率。序批式反应器由于有机械搅拌辅助传质,拥有各反应器中最优的活性炭容量利用率。本研究通过不同反应器吸附去除BPA的比较研究,为实际的废水吸附深度处理工艺的设计和设备选型提供了有价值的参考。The experiment investigated the adsorption behavior and adsorption capacity utilization efficiency of the activated carbon in different reactors.The results showed that,for the activated carbon in a fixed bed reactor,a lower flow rate and a higher filling height could achieve a better adsorption and a higher removal efficiency on bisphenol A.In the case of the fluidized bed,under a constant total dosage,the utilization efficiency of the activated carbon could be further improved by using incremental additions.The sequencing batch reactor,with a mechanical agitation for enhanced mass transfer,exhibited the highest utilization efficiency of the activated carbon among all the reactors.It provided valuable references for the design and selection of the equipments for the practical wastewater adsorption treatment process.
