严格的环保标准是SO2污染治理和控制的重要依据和推动力

火电厂排放的二氧化硫形成的酸雨已严重危害人类的生存环境，国家由此重新修订了(火电厂大气污染物排放标准)，严格了火电厂SO2排放的控制要求，强制要求火电厂必须安装烟气脱硫装置。本文从我国实际情况出发．比较分析了干法、半干法和湿法脱硫技术工艺，提出了适合有色金属企业一氧化铝厂配套建设的热电厂的烟气脱硫方法。

Strict standards of environmental protection being the important basis and impetus for the harness and control of SO2 pollutants

Since the acid rain resulted from SO_2 discharged from coalfired power plant has already seriously endangered the survival of the human being.<> was revised to strictly control the discharge of SO_2 from the coal-fired power plant and force the coal-fired power plant to install fume desulphurization device.The paper compares and analyzes the dry,semi-dry and wet desulphurization processes and set forth the desulphurization process of fume suitable for the thermal power plant of alumina refinery.
