环境烟草烟雾污染物的净化试验

Investigation of Purifying Environmental Tobacco Smoke Pollutants

采用自行设计的基于负离子与光催化高级氧化耦合净化技术的空气净化装置,开展室内环境烟草烟雾的净化试验,运用色度分析(RGB对照)方法初步分析了颗粒物(PM2.5)的净化效果。结果表明,光催化氧化技术对NOx的净化效果显著,负离子对PM2.5的净化较为突出。该空气净化装置能有效地净化烟草烟雾。

A self-developed air purification device using negative ions and photocatalytic oxidation technology was adopted to perform the experiment in indoor to evaluate the tobacco smoke cleaning efficiency. The color analysis （RGB contrast） method was used for evaluation the purification rates of fine particulate matter （PM2.5 ）. The experiment results indicate that photocatalytic oxidation technology shows significant effects of purifying negative ions play an important role on cleaning PM2.5. The purification device can effectively purify the NO, and cigarettesmoke.
