摘要
甲醛是造成室内空气污染的一个主要方面。本研究采用玻璃仓模拟室内甲醛释放环境,定期测定甲醛浓度。选取自然通风法、活性炭吸附法、植物净化法及光催化氧化法,分别考察其对甲醛的去除效果。结果表明:8小时后自然通风法甲醛去除率为92.1%;活性炭法去除甲醛所需时间较长;鹅掌柴8小时后甲醛去除率达80%;在保证可见光照射的条件下,光触媒在8小时后最高去除率为50%。
Formaldehyde is one of the main causes of indoor air pollution.In this study,formaldehyde concentration was measured regularly in glass silo simulated indoor formaldehyde release environment.Natural ventilation method,activated carbon adsorption method,plant purification method and photocatalytic oxidation method were selected to investigate the removal effect of formaldehyde respectively.The results showed that the removal rate of formaldehyde by natural ventilation after 8 h was 92.1%.The removal time of formaldehyde by activated carbon method was longer.The formaldehyde removal rate reached 80%after 8 h.Under the condition of visible light irradiation,the maximum removal rate of photocatalyst after 8 h was 50%.
