摘　　要：该文设计了两极协同电催化臭氧处理垃圾渗滤液膜浓缩液的综合研究型实验。在全面分析废液水质的基础上,开展了电催化臭氧技术处理垃圾渗滤液的能效评价和降解机理探究。实验结果表明,垃圾渗滤液的COD高达11 600 mg/L,可生化性极差;采用电催化臭氧技术对废液进行预氧化,能在有效去除有机物的基础上,将可生化性系数(B/C比)从0.18显著提升至0.45,协同耦合作用显著。该实验将行业难题、创新成果与专业知识相结合,能够激发学生的学习热情,培养科学创新思维,提升解决复杂环境工程问题的综合能力。In this study,a comprehensive research-oriented experiment was designed for the treatment of highly-concentrated landfill leachate by bipolar synergistic electro-peroxone process.After comprehensive analysis of the wastewater matrix,the treatment efficiency,energy consumption,and degradation mechanism during the electro-peroxone treatment of landfill leachate were systematically investigated.The experimental results show that the COD of the landfill leachate is up to 11600 mg/L with relatively poor biodegradability.Compared with single electrolysis and ozonation,the electro-peroxone process not only improved the removal efficiency of organic pollutants,but also significantly increased the biodegradability coefficient(B/C ratio)from 0.18 to 0.45,showing an obviously synergistic effect for pre-oxidation of the landfill leachate.Thus,by integrating industry problems and innovative research results into professional knowledge,this comprehensive experiment can stimulate students’learning enthusiasm,cultivate their scientific innovative thinking,and improve their comprehensive ability to solve complex environmental engineering problems.
