Abstract

Experiments were carried out to remove various organic compounds (oxalic and ethylenediaminetetraacetic acids, and anionic and nonionic surfactants) by electrochemical anodic oxidation. The experiments were performed in an MB-11T-06 flow-through diaphragm electrochemical reactor manufactured by the Russian company ZAO Vitold Bakhir Institute of Electrochemical Systems and Technologies. It was shown that the electrochemical anodic oxidation is the most effective if the solution being treated contains chloride ions at a concentration of 0.5–1.0 g/dm³. Under these conditions, almost complete oxidation of the above organic substances is achieved. It was concluded that the method of electrochemical oxidation using flow-through diaphragm electrochemical reactors manufactured by the Russian company ZAO Vitold Bakhir Institute of Electrochemical Systems and Technologies is very promising for the removal of a wide range of organic substances from industrial wastewater, as well as liquid radioactive waste.

用电化学氧化法去除废水中的有机污染物

实验采用电化学阳极氧化法去除各种有机化合物（草酸、乙二胺四乙酸、阴离子和非离子表面活性剂）。实验是在俄罗斯 ZAO Vitold Bakhir 电化学系统和技术研究所制造的 MB-11T-06 流通隔膜电化学反应器中进行的。结果表明，如果被处理溶液中的氯离子浓度为 0.5-1.0 g/dm3，则电化学阳极氧化法最为有效。在这些条件下，上述有机物几乎可以完全氧化。结论是，使用俄罗斯 ZAO Vitold Bakhir 电化学系统和技术研究所生产的流动隔膜电化学反应器进行电化学氧化的方法，对于去除工业废水中的多种有机物质以及液体放射性废物非常有前途。
