英文摘要: With experimental investigation,mechanisms analysis, and model prediction methods, this study investigate the performance and mechaniam of an sorbent-based dynamic botanical air purification system for removing indoor total volatile organic compounds and particulate matter. The key parameters for the removal mechanisms will be determined. The performance demonstration of the botanical system for residential building application will be conducted through laboratory test and model prediction, which will provide reference data and thereotical basis for the application of botanical air filter in indoor pollutant control. Specific research content of the study include: (1) investigate the roles of plant leaves, adsorbent root bed, moisture in root bed and microbial in plant root in the overall purifying processes and determine corespongding key parameters with well-controlled environmental chamber tests. The target contaminants include the typical indoor volatile organic compounds (toluene) and particulate matter, and the tests will be conducted with concentration levels simulating the typical indoor pollution levels in newly built or renovated residential building; (2)validate the performance of the dynamic plant purification device in simulated newly renovated living room,smoking room,and kitchen environment; (3)
