Fresh water is a fundamental source for humans, hence the recent shrinkage in freshwater and increase in water pollution are imperative problems that vigorously affect the people and the environment worldwide. The breakneck industrialization contributes to the procreation of substantial abundance of wastewater and its treatment becomes highly indispensable. Perchlorate and nitrate containing wastewaters poses a serious threat to human health and environment. Conventional biological treatment methods are expensive and also not effective for treating wastewater effectively and incapable of in situ bioremediation. Bioelectrochemical systems are emerging as a new technology platform for a sustainable removal of such contaminants from wastewater streams. This article reviews the state of art of bioelectroremediation of contaminated waters with perchlorate and nitrate. Different aspects of this technology such as configuration and design, mode of operation and type of substrate are considered in detail.
淡水是人类的基本资源，因此，最近淡水的减少和水污染的增加是全球性的紧迫问题，对人类和环境产生了巨大的影响。飞速发展的工业化导致了大量废水的产生，因此对其进行处理变得非常必要。含有高氯酸盐和硝酸盐的废水对人类健康和环境构成严重威胁。传统的生物处理方法不仅昂贵，而且无法有效地处理废水，也无法进行原位生物修复。生物电化学系统作为一种从废水中去除这些污染物的可持续新技术平台正在兴起。本文综述了利用生物电化学方法修复受高氯酸盐和硝酸盐污染的水的最新进展。本文详细考虑了该技术的不同方面，如配置和设计、操作模式和底物类型。
