【广角】百姓视角说雾霾 （英文版）
作者：李延新
中文摘要：雾霾是“雾”与“霾”的结合物，而“霾”则是颗粒物的统称，雾霾中粒径小于2.5微米的主要成分是硫酸盐和硝酸盐。雾霾的形成与气象条件密切相关。防治雾霾的方法为消除硫酸盐、硝酸盐及人为排放的水汽。从燃烧的源头消除雾霾可采用颠覆性的清洁高效燃烧技术在燃烧阶段实现脱硫与脱硝。治理非常规污染物刻不容缓。

How to Cope with Haze?
Author: Li Yanxin
Abstract:
“HAZE” is actually the hybrid of fog and haze. The latter haze refers to all particulate matter (PM). Fine particulate matter (PM2.5) mainly contains sulphate and nitrate. The formation of haze is decided by the weather. Key measures to prevent HAZE is to eliminate sulphate, nitrate, and man-made water vapor. To nip HAZE in the bud, revolutionary clean and efficient burning technology, which could realize desulfurization and denitration, is needed. Dealing with unconventional emissions is a matter of great urgency.
Key words: haze, wet desulphurization, condensable particulate matter (CPM), water vapor, pollution control, unconventional emissions
