The bioremediation of emerging pollutants in wastewater via algal biotechnology has been emerging as a cost-effective and low-energy input technological solution. However, the algal bioremediation technology is still not fully developed at a commercial level. The development of different technologies and new strategies to cater specific needs have been studied. The existence of multiple emerging pollutants and the selection of microalgal species is a major concern. The rate of algal bioremediation is influenced by various factors, including accidental contaminations and operational conditions in the pilot-scale studies. Algal-bioremediation can be combined with existing treatment technologies for efficient removal of emerging pollutants from wastewater. This review mainly focuses on algal-bioremediation systems for wastewater treatment and pollutant removal, the impact of emerging pollutants in the environment, selection of potential microalgal species, mechanisms involved, and challenges in removing emerging pollutants using algal-bioremediation systems.
利用藻类生物技术对废水中新兴污染物进行生物修复，已成为一种具有成本效益和低能耗的技术解决方案。然而，藻类生物修复技术仍未完全开发到商业水平。已经研究了开发不同技术和新策略以满足特定需求的方法。多种新兴污染物的存在和微藻物种的选择是一个主要关注点。藻类生物修复的速度受到多种因素的影响，包括在中试研究中的意外污染和操作条件。藻类生物修复可以与现有的处理技术相结合，以有效地从废水中去除新兴污染物。本综述主要关注用于废水处理和污染物去除的藻类生物修复系统、环境中新兴污染物的影响、潜在微藻物种的选择、所涉及的机制以及利用藻类生物修复系统去除新兴污染物的挑战。
