针对当前电化学处理含盐有机废水效能低且易生成有毒中间产物这一问题,提出利用阴-阳极协同强化体系矿化效能同时控制有毒中间产物产生。本项目重点研究活性和非活性阳极氧化与阴极电芬顿过程匹配、考察阴-阳极协同氧化过程中有毒中间产物生成规律、通过阳极材料比选和电芬顿阴极优化、分析工艺参数对降解效果和有毒副产物生成规律的影响、探索活性物种产生及利用等一系列电化学氧化的关键科学问题,阐明难降解目标污染物分子在阳极强化电芬顿体系中的氧化过程所遵循的反应模型和降解机理,完善阳极强化光电芬顿体系的基础理论,揭示阳极表面吸附态•OH与溶液中•OH影响污染物降解及有毒中间产物生成规律。理解高含盐有机废水在电化学降解中的污染物降解和副产物生成共性特征,力争开发出一种在高含盐废水处理等方面有应用价值,安全、稳定、高效、低成本的环境友好型集成技术,为新型电化学氧化工艺的研究提供系统的理论基础和科学依据。
英文摘要
Nowadays, the treatment of saline organic wastewater by the electrochemical advanced oxidation processes (EAOPs) is often inefficient and easy to produce toxic byproducts, it is proposed to improve the mineralization efficiency and control the generation of toxic intermediates by synergistic treatment of the anodic oxidation (AO) and the electro-Fenton (EF) process. This project focuses on the matching the AO by an active or inactive anode with the EF process, investigating the formation of toxic byproducts in the AO-EF process, selecting anodic materials and optimizing the cathode properties, analyzing the influence of parameters on the degradation ability and the formation of toxic by-products; exploring the key scientific issues in EAOPs such as the generation and utilization of the Reactive Oxidative Substances (ROS). The model and degradation mechanism of refractory target pollutant molecule in AO-enhanced EF system are clarified, the basic theory of the AO-enhanced photoelectro-Fenton (PEF) system is improved, and the mechanisms of pollutant degradation and toxic intermediates formation affected by the •OH adsorbed on anode surface and/or the •OH in solution are revealed. For understanding the common characteristics of pollutant degradation and by-product formation in electrochemical degradation of highly saline organic wastewater, we strive to develop a safe, stable, efficient and low-cost environment-friendly integrated technology for the treatment of highly saline wastewater, and provide a new technical route for the effective removal of organic pollutants.
