Abstract

Electrocatalytic treatment of chemical saline wastewater showed great technical advantages due to its characteristics of simple operation, high catalytic efficiency and little secondary pollution. The review takes the classification and composition of titanium-based anodes as the starting point. Typical studies of wastewater treatment by electrocatalytic technology based on free radicals and non-free radicals were also discussed. Combined with the previous researches about electrocatalytic mechanisms in recent years, the mechanisms of titanium-based anodes were analyzed in terms of ·OH, active chlorine and others. The studies on titanium-based anodes in chemical wastewater containing different salt concentrations, such as dye wastewater, coal chemical wastewater, landfill leachate wastewater, fertilizer and pesticide production wastewater, etc., were thoroughly examined. According to the amount of electricity required for the removal of organic matter per unit, the energy consumption of titanium-based anodes for wastewater treatment by electrochemistry was described. The review would provide theoretical basis and technical support for electrocatalytic treatment of chemical saline wastewater.

钛基阳极的电催化机理与含盐化学废水处理的研究进展：简评

电催化处理含盐化工废水具有操作简单、催化效率高、二次污染小等特点，具有很大的技术优势。本综述以钛基阳极的分类和组成为切入点。还讨论了基于自由基和非自由基的电催化技术处理废水的典型研究。结合近年来有关电催化机理的研究，从-OH、活性氯等方面分析了钛基阳极的机理。深入研究了钛基阳极在染料废水、煤化工废水、垃圾填埋场渗滤液废水、化肥农药生产废水等不同含盐浓度的化工废水中的应用。根据单位有机物去除所需的电量，描述了电化学处理废水的钛基阳极能耗。该综述将为电催化处理含盐化工废水提供理论依据和技术支持。

期刊介绍： Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
