摘要

近年来,工业不断增加,含油废水的数量也随之增加,含油废水被认为是有害废物,因为它们含有危害环境和人类健康的各种重金属和油类。在过去的二十年里,人们越来越多地研究如何高效、环保地处理废水的新技术。最近的一种污水处理方法是电化学工艺的应用,如电fenton工艺,它属于电化学高级氧化工艺和电絮凝工艺。这项工作的目的是去除来自油类和油脂分离器的废水中的有机污染物和重金属,这些油类和油脂分离器用于清洁交通区域的雨水径流。使用不锈钢、铁和铝电极会产生电氧化、电还原和电凝。在15 a的电流下,COD的处理效率为50%,矿物油的处理效率为73%。在110 a的电流下,COD的处理效率为96%,矿物油的处理效率为90%。

Treatment of wastewater from separators for rainfall runoff using electrochemical oxidation processes
In recent years, industry has increased and with it the amount of oily wastewater, which are considered hazardous waste because they contain various types of heavy metals and oils that endanger the environment and human health. In the last twenty years, there has been increased research on new technologies to treat wastewater as efficiently and environmentally friendly as possible. A recent approach to wastewater treatment is the application of electrochemical processes such as the electro-Fenton process, which belongs to the group of electrochemical advanced oxidation processes and electrocoagulation. The aim of this work was to remove organic contaminants and heavy metals from wastewater originating from oil and grease separators that clean stormwater runoff from traffic areas. The use of stainless steel, iron and aluminum electrodes results in electrooxidation, electroreduction and electrocoagulation. At a current of 15 A the treatment efficiency was 50% for COD and 73% for mineral oil. At a current of 110 A the treatment efficiency was 96% for COD and 90% for mineral oil.
