Phenol and phenolic derivatives found in different industrial effluents are highly toxic and extremely harmful to human and the aquatic ecosystem. In the past, trickle bed reactor (TBR), reverse osmosis (RO) and other processes have been used to remove phenol from wastewater. However, each of these technologies has limitations in terms of the phenol concentration in the feed water and the efficiency of phenol rejection rate. In this work, an integrated hybrid TBR–RO process for removing high concentration phenol from wastewater is suggested and model-based simulation of the process is presented to evaluate the performance of the process. The models for both TBR and RO processes were independently validated against experimental data from the literature before coupling together to make the hybrid process. The results clearly show that the combined process significantly improves the rejection rate of phenol compared to that obtained via the individual processes.

在不同的工业废水中发现的苯酚和酚类衍生物具有剧毒，对人类和水生生态系统极为有害。过去，滴流床反应器（TBR），反渗透（RO）和其他工艺已用于去除废水中的苯酚。然而，这些技术中的每一种在给水中的苯酚浓度和苯酚截留率的效率方面都有局限性。在这项工作中，提出了一种用于从废水中去除高浓度苯酚的集成混合TBR-RO工艺，并提出了基于模型的工艺模拟以评估工艺性能。在结合在一起以形成混合过程之前，针对文献中的实验数据对TBR和RO过程的模型进行了独立验证。
