摘要

烟气脱硫是目前控制和减少工业上SO2排放的主要技术。以石灰/石灰石法为代表的传统脱硫技术存在吸附剂再生困难、脱硫过程易结垢导致设备和管路堵塞、副产物难以处理、易造成二次污染等问题。针对传统烟气脱硫技术的局限性，我们在前期的研究工作中，开发了一种脱硫效率高、吸附剂再生性能好、操作简便、耗水量少、硫资源可灵活回收利用的烟气脱硫技术。该技术利用超声法制备了沸石咪唑盐骨架ZIF8，其具有超大比表面积，因此可高效地吸附烟气中的SO2。本文以此为基础，将ZIF8烟气脱硫技术运用于本科实验教学。在本设计实验中，吸附剂ZIF8的制备方法简单，烟气脱硫实验的可操作性强，重复性好。通过开展本实验，拓展了本科生的视野，提升了本科生的专业素养，进一步增加了其对专业综合实验的兴趣；本设计实验还可让学生对大气污染物SO2的减排有深刻的了解和认识，增强学生环境保护的意识和理念。
