doi:10.16085/j.issn.1000-6613.2020-0877

摘要/Abstract

摘要：

电絮凝是一种用于处理不同类型饮用水和废水有效的电化学方法，近年来由于其高效地处理大量难处理污染物的能力而受到了广泛的关注。它成功地处理了有机和无机污染物且同时却很少产生副产物。在过去的十年里大量的研究致力于利用电絮凝处理饮用水和废水，从受污染的地下水到受高度污染的炼油厂废水都是其处理范围。本文首先介绍了电絮凝的基本原理及优缺点并回顾了近年来有关电絮凝用于水处理的文献，重点关注当前在饮用水和废水中的具体应用方面取得的成功以及未来应用的潜力。随后分析了影响电絮凝效率的几个因素，最后指出最近的电絮凝大多集中在去除特定污染物的研究上，而没有关注开发模型或工业应用，并且如果能降低电絮凝的成本，此方法将会有一个巨大的突破。

Abstract:

Electrocoagulation is an effective electrochemical method for the treatment of different types of drinking water and wastewater. In recent years, due to its high efficiency in the treatment of a large number of difficult pollutants, it has attracted widespread attention. It has successfully treated organic and inorganic pollutants with little by-products. In the past decade, a large number of researches have been devoted to the treatment of drinking water and wastewater by electrocoagulation, ranging from polluted groundwater to highly polluted refinery wastewater. This paper first introduces the basic principle, advantages and disadvantages of electrocoagulation, and reviews the recent literature on the application of electrocoagulation in water treatment, focusing on the current success in the specific application of drinking water and wastewater and the potential for future application. Then it analyzes several factors that affect the efficiency of electrocoagulation, and points out that most of the recent electrocoagulation research focuses on the removal of specific pollutants, without focusing on the development of models or industrial applications, and if the cost of electrocoagulation can be reduced, this method will have a huge breakthrough.
