超临界技术在环境工程实验教学中的应用

Application of supercritical technology in experiment teaching of environmental engineering

超临界流体具有热导率高、扩散传质力强等特点,尤其在环保领域,超临界技术在有机废水、城市污泥、持久性有机污染物的处理处置方面具有优异的效果。但是在我国高等院校环境工程实验教学中,很少有设置超临界技术的实验项目。通过对超临界流体技术的介绍、设备选型、溶剂选取以及超临界流体在环境工程方面的具体应用实例,以期培养学生对超临界流体技术的兴趣,提高学生的创新与实践能力。

For supercritical fluid,due to the special characteristics of high thermal conductivity,high diffusion and mass transfer,especially in the field of environmental protection,supercritical technology has an excellent effect on the disposal of organic wastewater,urban sewage sludge,and persistent organic pollutants. However,few supercritical technology experimental projects was set in the environmental engineering experiment teaching program in our country. Therefore,this paper try to cultivate students＇ interest and improve the students＇ innovation and practice ability based on the introduction of supercritical fluid technology,equipment and solvent selection and several supercritical fluid actual application cases of environmental engineering.
