摘要
建设了活性炭催化臭氧降解染料废水的设计性实验项目。采用拼图式教学法(Jigsaw)实现生生之间、团队间合作式学习,更好地帮助学生掌握这一技术的应用现状、原理及工艺条件。在此基础上,学生通过自主设计单独活性炭、单独臭氧、活性炭催化臭氧三个实验去除亚甲基蓝染料废水,分析判断活性炭在该工艺技术中的作用。本实验项目有助于提高学生的自学能力、协作能力和研究能力。
A new design experiment project of activated carbon catalytic ozonation for dye wastewater treatment was constructed.The application of Jigsaw teaching method promoted the cooperation between the students as well as the groups,which helps the students to better master the application,principle and process conditions of this technology.On this basis,students independently designed three experiments to remove the methylene blue of dye wastewater including sole ozone oxidation,sole activated carbon adsorption and activated carbon catalytic ozone.The role of activated carbon in the removal of dye can be analyzed by the students.This experimental project helps improve students self-learning ability,collaboration ability and research ability.
