除了减少建筑物能源需求的需求日益增长外，还出现了寻找改善室内空气质量的可持续方法的需求。绿色墙技术的最新进展导致了被称为植物生物过滤器的活化系统的发展，该活化系统使空气穿过植物生长基质以增加内部大气环境暴露于植物基质系统的在空气污染物去除中具有活性的组分的速率。该技术的发展正朝着建筑物空调和通风系统内的绿色墙集成方向发展。本文介绍的工作描述了确定模块化植物生物过滤器的功能所必需的几个参数的评估，以及系统地确定该设备的过滤性能的实验，特别是评估和定义了单程颗粒物雷姆过滤效率。总悬浮颗粒物的最大过滤效率在通过0.25 m（2）过滤器的空气流速为11.25 Ls（-1）时达到峰值，空气流速的任何增加都会导致效率降低。该系统记录的总悬浮颗粒物去除率为53.35 +/- 9.73%，PM10去除率为53.51 +/- 15.99%，PM2.5去除率为48.21 +/- 14.71%。与没有植物成分的系统的单程效率以及常见的管道内折叠面板空气过滤器进行了比较，表明如果系统符合当前的空气过滤标准，则需要进一步开发以提高系统的过滤能力。(C)2017爱思唯尔有限公司版权所有
In addition to the growing requirement to reduce building energy needs, demand has arisen to find sustainable methods of improving indoor air quality. Recent advances in green wall technology have led to the development of activated systems, termed botanical biofilters, that move air throligh the plant growth substrate to increase the rate at which the interior atmospherit environment is exposed to the components of the plant-substrate system that are active in air pollutant removal. Development of this technology is moving towards green wall integration within building air conditioning and ventilation systems. The work presented here describes an evaluation of several parameters essential for determining the functionality of a modular botanical biofilter, as well as experiments to systematically determine the filtration performance of the device, specifically the single-pass particulate rem filtration efficiency was evaluated and defined. The maximum filtration efficiency for total suspended particulate matter peaked at an air flow rate of 11.25 Ls(-1) through the 0.25 m(2) filter, with any increases in air flow rate met with a reduction in efficiency. The system recorded removal efficiencies were 53.35 +/- 9.73% for total suspend particles, 53.51 +/- 15.99% for PM10, and 48.21 +/- 14.71% fdr PM2.5. Comparisons Were made against the single pass efficiency of the system without the botanical component, as well as a common in-duct pleated panel air filter, indicating that further development is required to enhance the filtration capacity of the system if it is match current air filtration standards.
