钙法脱硫技术亟待解决的环保问题及相应对策

Environmental protection problems in calcium desulfurization technology and corresponding countermeasures

结合我国钙法脱硫技术的发展现状,分析了亟待解决的环保问题,其中主要是将SO_(2)废气变成工业废渣硫石膏,治标不治本,造成二次污染,浪费硫资源,增加碳排放等。针对这一系列环保问题,提出推广氨法脱硫技术,将钙法脱硫改为氨法或磷矿石法脱硫技术等对策及建议。

Through development status of calcium-based desulfurization technology,environmental problems to be solved urgently are analyzed,of which waste gas containing SO_(2)are turned into industrial waste sulphur gypsum,treating symptoms but not root cause,causing secondary pollution,waste sulphur resources,increasing carbon emissions.According to the environmental protection issues,corresponding countermeasures and suggestions on popularizing ammonia desulfurization technology and changing calcium desulfurization into ammonia or phosphate ore desulfurization technology are proposed.
