灰霾治理之治标方法

Abstract

分析了治理已形成的灰霾空气所用方法的现状，治理方法包括过滤、吸附、湿法除尘、水溶液吸收、静电除尘、负离子、催化等基本方法及其组合，应用于室内、室外、街道、城市区域、大气等范围。室内灰霾治理研究充分，技术成熟，已有商品化装置。随着灰霾空气治理范围增大，治理装置体积增大、费用增加、难度增加。对大范围灰霾治理，使用方便、起效快、持续时间长、费用低的治理方法仍然是一个难题，成为研发重点。 Current situation was analyzed for temporary method to control haze that has appeared. The methods include basic means and their combination, such as filtration, adsorption, wet dust, absorption, electrostatic precipitation, negative ion and catalysis, which are applied in indoor, outdoor, street side, city region, atmosphere and other areas. There are mature technology and commercial devices indoors after full research. The controlling equipment volume, cost and difficulty increase along with haze area enlarged. To large area haze, it is still a difficult problem and becomes a focal point to control haze quickly at low cost for long duration with convenient method.
