燃煤 SO2污染及其控制技术综述崔敬媛 焦红光 陈清如 张春光(河南理工大学 材料科学与工程学院 ,河南 焦作 454003)摘要 作为世界上最大的煤炭生产国和消费国,“煤烟”型大气污染是我国当前面临的主要环境问题之一,其中由于燃煤排放 SO2所引发的“酸雨”危害尤为突出
本文首先论述了我国 SO2的污染状况,指出劣质燃煤是造成污染的最主要原因,在此基础上分析对比了当前燃前、燃中和燃后常用 SO2污染控制技术的优缺点,认为基于我国基本国情,为有效控制当前的 SO2污染,应优先发展燃前微粉煤干法脱硫技术
Abstract As the largest coal producing and consuming country in the world, air pollution of " soot " type is one of the main environmental problems which our country faces at present, among them because the fire coal discharges " acid rain " that SO2 initiates to it is particularly outstanding to endanger
This text describes the pollution state of SO2 of our country at first, point out the inferior fire coal is a main reason for pollution, before analyzing and comparing with firing at present on this basis, fire and daily SO 2 polluted the
