碳中和背景下自由沉淀教学实验改革

Reform of Free Precipitation Teaching Experiment Under the Background of Carbon Neutrality

为响应“碳达峰碳中和”的国家战略,在实验教学过程中贯彻绿色低碳理念,针对目前自由沉淀教学实验装置与方法存在的不足,通过沉淀柱小型化、以浊度去除率表征沉淀效率及Origin软件计算总沉淀效率等主要改革措施,构建了具有减污降碳效能的自由沉淀教学实验方法。理论分析与教学实践均表明改革后获得的实验结果可充分验证自由沉淀的基本原理,实现教学目标,激发家国情怀及社会主义核心价值观培育,提升了育人效果。

In order to actively respond to the national strategy of“carbon peaking and carbon neutralization”and implement the concept of green and low carbon in the process of experimental teaching,this paper analyzed the shortcomings of the current experimental devices and methods of free precipitation teaching.The main reform measures such as miniaturization of precipitation column,characterization of precipitation efficiency by turbidity removal rate,and calculating total precipitation efficiency with Origin software were adopted,then a free precipitation teaching experiment method with the characteristics of pollution and carbon emissions reduction was constructed.Both theoretical analysis and teaching practice showed that the experimental results can not only fully verify the basic principle of free precipitation and achieve the teaching objectives,which can enhance the cultivation of patriotism and socialist core values,thus improving the education effect.
