Abstract:

Industrial wastewater is generally characterized by poor biochemical properties, with many kinds of pollutants, high organic content and difficulty in degradation, etc. It is difficult to meet the discharge standards with conventional treatment methods. The deep treatment process of wastewater represented by the electrochemical advanced oxidation process can effectively treat industrial wastewater, which is one of the research hotspot for environmentalists in recent years. Boron-doped diamond (BDD) electrode has excellent physicochemical properties and is the most ideal and efficient anode material for the electrochemical oxidation treatment of wastewater. However, the research on the application of BDD electrodes in large size and the treatment of real industrial wastewater has not been summarized in time. This paper firstly reviewed the research progress on industrial wastewater characteristics, process principles, BDD electrode characteristics and preparation methods, treatment cases and optimization of process parameters involved in this process based on the electrochemical advanced oxidation process with BDD electrodes, and focused on large laboratory installations, pilot plants, and real industrial wastewater under different pollution systems. In the following, the development of BDD electrode materials and the technical characteristics of different types of processes were summarized. At the same time, the research progress of process optimization and the main reasons that currently limited the large-scale industrial application of this technology were also discussed. Finally, this paper concluded with an outlook on the industrial application prospects and main development directions of the electrochemical advanced oxidation process based on BDD electrodes.

摘要:

工业废水普遍具有可生化性差、污染物种类多、有机物含量高、难降解等特点,常规处理手段难使其达标排放。以电化学高级氧化工艺为代表的污水深度处理工艺处理污水效果显著,是近年来环境工作者的研究热点之一。掺硼金刚石(boron-doped diamond,BDD)电极理化性质优异,是目前电化学高级氧化处理废水最为理想高效的阳极材料,但关于大尺寸BDD电极的应用及处理真实工业废水的研究情况尚未及时总结归纳。本文以基于BDD电极的电化学高级氧化工艺过程为对象,对该过程涉及到的废水特点、工艺原理、BDD电极特点及制备方法、处理案例和工艺参数优化等方面的研究进展进行综述,重点聚焦不同污染体系下的大型实验室装置、中试装置和处理真实工业废水案例,总结了BDD电极材料开发情况和不同类型工艺的技术特点,探讨了工艺优化方面的研究进展和目前限制该技术大规模工业化应用的主要原因。最后对基于BDD电极的电化学高级氧化工艺应用前景和重点发展方向作出了展望。
