室内空气污染影响着全球人口,特别是在发达国家,人们90%的时间都在室内。最近的大流行通过依靠室内空间和远程工作的生活方式加剧了暴露。挥发性有机化合物是一组低浓度对人体健康有害的室内空气污染物。植物可以去除室内挥发性有机化合物是很普遍的。直到今天,研究结合了植物修复的原理,生物过滤,和生物修复成一种整体和可持续的技术,称为植物生物过滤。总的来说,它的主要优势是使用低能量输入分解和生物降解污染物的能力。这不同于将VOC转移到另一相的传统系统。此外,它提供了额外的好处,如降低室内空气健康成本,提高工作效率,和幸福。然而,关于植物的作用,该领域存在许多差异,基材,和叶球细菌。然而,它们的作用已经被理论化;它的稳定性在工程方法中鲜为人知。以前的研究没有解决叶球的生物增强来提高性能,这可以增强系统。此外,大多数实验都使用小室在实验室规模研究了被动盆栽系统,这使得很难将研究结果推断为有形参数来设计技术。有源系统被认为更有效,但需要更多的维护和知识专家;此外,积极流动对长期的影响还没有完全理解。此外,系统建模被过度简化,限制了理解和优化。这篇评论揭示了该领域的收获和差距,比如概念,实验,和建模。我们相信,采用包括实验在内的多学科方法,多物理场建模,微生物群落分析,与室内空气部门的合作将使这项技术得以优化,并促进其采用。
Indoor air pollution affects the global population, especially in developed countries where people spend around 90% of their time indoors. The recent pandemic exacerbated the exposure by relying on indoor spaces and a teleworking lifestyle. VOCs are a group of indoor air pollutants with harmful effects on human health at low concentrations. It is widespread that plants can remove indoor VOCs. To this day, research has combined principles of phytoremediation, biofiltration, and bioremediation into a holistic and sustainable technology called botanical biofiltration. Overall, it is sustained that its main advantage is the capacity to break down and biodegrade pollutants using low energy input. This differs from traditional systems that transfer VOCs to another phase. Furthermore, it offers additional benefits like decreased indoor air health costs, enhanced work productivity, and well-being. However, many disparities exist within the field regarding the role of plants, substrate, and phyllosphere bacteria. Yet their role has been theorized; its stability is poorly known for an engineering approach. Previous research has not addressed the
bioaugmentation of the phyllosphere to increase the performance, which could boost the system. Moreover, most experiments have studied passive potted plant systems at a lab scale using small chambers, making it difficult to extrapolate findings into tangible parameters to engineer the technology. Active systems are believed to be more efficient yet require more maintenance and knowledge expertize; besides, the impact of the active flow on the long term is not fully understood. Besides, modeling the system has been oversimplified, limiting the understanding and optimization. This
review sheds light on the field\'s gains and gaps, like concepts, experiments, and modeling. We believe that embracing a multidisciplinary approach encompassing experiments, multiphysics modeling, microbial community analysis, and coworking with the indoor air sector will enable the optimization of the technology and facilitate its adoption.
