可吸入颗粒物纤维净化技术研究现状及发展趋势

Inhalable particulate matter has small particle size and large specific surface area, so it is easy to adsorb harmful substances in the air, which has seriously affected the global environment and human health. Nowadays, the purification technologies for inhalable particulates include electrostatic purification technology and filter-type purification technology, etc. Because electrostatic purification technology can not prevent the generation of ozone pollutants, which has been limited in the field of indoor air purification application, and filtration purification technology also has some troubles such as filter material with greater resistance and that need to be replaced regularly，the fiber filtration technology can overcome the above shortcomings. This paper summarizes the situation of fiber filtration technology, and development direction is pointed out.
