摘要
基于对实验过程中产生的废液的无害处理与回收利用的探究,对部分实验中所排放的废液进行分类收集,将排放量较大的4种重金属(Hg、Pb、Cr、Ag),以及酸碱废液等作为无害处理对象,并进行处理后的达标检测及回收利用。在项目的开展中,学生自行设计并优化废液处理方案,预期通过学生主导、教师辅导的实验教学模式培养学生良好的实验习惯,提升学生自主的实验操作能力,同时强化学生的环境保护意识。
Based on the exploration of the recycling and hannless treatment of waste liquid produced during the experimental process, the waste liquid released in some experiments was classified and collected, and tour metals such as Hg, Pb, Cr, Ag, acid and alkali waste were used as harmless treatment objects, and then they were tested and recycled. In the project, students designed and optimized the solution of waste liquid by themselves. Through the experimental teaching mode of student - orientation and teacher assistant, the good experimental habits of students were expected to be cultivated, and the students＇ experimental skills were im- proved. Meanwhile, the students＇ environment awareness were strengthened.
