室内挥发性有机物的净化技术研究进展
Research progress on the purification technologies of indoor volatile organic compounds
摘要
Abstract
Volatile organic compounds (VOCs),which seriously threaten human health,have been the key factor influencing indoor air quality,and need to be treated effectively.In this paper,the main purification technologies of indoor VOCs were reviewed,including green plants,adsorption,non-thermal plasma (NTP),metal catalytic oxidation,and photocatalytic oxidation.The principles and influence factors of the purification technologies were summarized,and the merits and faults of each technology and problems need to be resolved in the future were analyzed.Green plants are just suitable for low concentration pollutants,and are usually used as supplementary means.The core of adsorption is the adsorbent,and the replacement of regeneration of adsorbent should be considered.For non-thermal plasma,the removal efficiency of VOCs by NTP technology is high,but the cost is high.As for metal catalytic oxidation method,the metal oxide catalysts with low price and high efficiency are needed to be developed.For photocatalytic oxidation technology,the current study is focused on the modification of TiO2 and improvement of light conversion efficiency.This paper also briefly presents the current situation of the air purifier market and the proportion of various technologies in the market.Then the technical research hot spots in the future were proposed.关键词
