摘要
探索性实验作为一种新型教学实验,不但有利于提高学生的理论知识水平,而且可以培养学生独立思考和综合运用专业知识的能力。本文针对油田中常见但较难处理的含聚污水处理问题,介绍了一个新型实验,引导学生以绿色化合物壳聚糖和多巴胺为主要原料,合成具有高黏附强度的新型复合絮凝剂,并用于含聚污水的絮凝处理。该实验涉及化学合成设计方法和物化性质表征手段,实现了实验中间产物的再利用,达到了污水中有害物的减量化与无害化综合处理的目的,对于提升学生的创新研究意识与实践能力、促进环境的可持续发展具有积极的作用。
Exploratory experiments,as a kind of new experiment,could help to improve the theoretical knowledge of students and to cultivate their abilities of independent thinking and comprehensively utilizing professional knowlege.The polymer-containing wastewater,common in oil field,is hard to be processed for disposal.This paper introduces an experiment,which could instruct students to use green materials like chitosan and dopamine,to synthesize highly adhesive flocculants,and to flocculate such wastewater.This experiment teaches the synthesis method,the physchemical characterization tools,and realizes the comprehensive reuse of waste,reduction and elimination of harmful substances in wastewater.This new teaching experiment has a positive role on enhancing the innovation consciousness and practical skills of students,and promoting the sustainable development of environment.
