Organic pollutants in the air have serious consequences on both human health and the environment. Among the various methods for removing organic pollution gas, biotrickling filters (BTFs) are becoming more and more popular due to their cost-effective advantages. BTF can effectively degrade organic pollutants without producing secondary pollutants. In the current research on the removal of organic pollutants by BTF, improving the performance of BTF has always been a research hotspot. Researchers have conducted studies from different aspects to improve the removal performance of BTF for organic pollutants. Including research on the performance of BTF using different packing materials, research on the removal of various mixed pollutant gases by BTF, research on microbial communities in BTF, and other studies that can improve the performance of BTF. Moreover, computational fluid dynamics (CFD) was introduced to study the microscopic process of BTF removal of organic pollutants. CFD is a simulation tool widely used in aerospace, automotive, and industrial production. In the study of BTF removal of organic pollutants, CFD can simulate the fluid movement, mass transfer process, and biodegradation process in BTF in a visual way. This review will summarize the development of BTFs from four aspects: packing materials, mixed gases, micro-organisms, and CFD, in order to provide a reference and direction for the future optimization of BTFs.
空气中的有机污染物对人类健康和环境都有严重的影响。在去除有机污染气体的各种方法中，生物滴滤塔（BTF）由于其具有成本效益的优势而越来越受欢迎。BTF 可以有效地降解有机污染物，而不会产生二次污染物。在当前使用 BTF 去除有机污染物的研究中，提高 BTF 的性能一直是一个研究热点。研究人员从不同方面进行了研究，以提高 BTF 对有机污染物的去除性能。包括使用不同填充材料的 BTF 性能研究、BTF 去除各种混合污染物气体的研究、BTF 中微生物群落的研究以及其他可以提高 BTF 性能的研究。此外，计算流体动力学（CFD）被引入到 BTF 去除有机污染物的微观过程研究中。CFD 是一种广泛应用于航空航天、汽车和工业生产的模拟工具。在 BTF 去除有机污染物的研究中，CFD 可以直观地模拟 BTF 中流体的流动、传质过程和生物降解过程。本综述将从包装材料、混合气体、微生物和 CFD 四个方面总结 BTF 的发展情况，以期为未来 BTF 的优化提供参考和方向。
