Abstract:
The existence of continually increasing concentrations of antibiotics in the environment is a serious potential hazard due to their toxicity and persistence. Unfortunately, conventional treatment techniques, such as those utilized in wastewater treatment plants, are not efficient for the treatment of wastewater containing antibiotic. Recently, algae-based technologies have been found to be a sustainable and promising technique for antibiotic removal. Therefore, this review aims to provide a critical summary of algae-based technologies and their important role in antibiotic wastewater treatment. Algal removal mechanisms including bioadsorption, bioaccumulation, and biodegradation are discussed in detail, with using algae-bacteria consortia for antibiotic treatment, integration of algae with other microorganisms (fungi and multiple algal species), hybrid algae-based treatment and constructed wetlands, and the factors affecting algal antibiotic degradation comprehensively described and assessed. In addition, the use of algae as a precursor for the production of biochar is highlighted, along with the modification of biochar with other materials to improve its antibiotic removal capacity and hybrid algae-based treatment with advanced oxidation processes. Furthermore, recent novel approaches for enhancing antibiotic removal, such as the use of genetic engineering to enhance the antibiotic degradation capacity of algae and the integration of algal antibiotic removal with bioelectrochemical systems are discussed. Finally, some based on the critical review, key future research perspectives are proposed. Overall, this review systematically presents the current progress in algae-mediated antibiotic removal technologies, providing some novel insights for improved alleviation of antibiotic pollution in aquatic environments.
摘要:
由于抗生素的毒性和持久性,环境中不断增加的浓度是一种严重的潜在危害。不幸的是,常规处理技术,例如在污水处理厂中使用的那些,对含有抗生素的废水的处理效率不高。最近,已发现基于藻类的技术是一种可持续且有前途的抗生素去除技术。因此,这篇综述旨在提供基于藻类的技术及其在抗生素废水处理中的重要作用的关键总结。藻类去除机制包括生物吸附,生物蓄积性,详细讨论了生物降解,使用藻类细菌联盟进行抗生素治疗,藻类与其他微生物(真菌和多种藻类)的整合,混合藻类处理和人工湿地,并对影响藻类抗生素降解的因素进行了全面的描述和评价。此外,强调了使用藻类作为生产生物炭的前体,随着生物炭与其他材料的改性,以提高其抗生素去除能力和混合藻类处理与高级氧化工艺。此外,最近提高抗生素去除的新方法,如利用基因工程来提高藻类的抗生素降解能力,以及藻类抗生素去除与生物电化学系统的整合。最后,一些是基于批判性审查,提出了未来的研究重点。总的来说,这篇综述系统地介绍了藻类介导的抗生素去除技术的最新进展,为改善水生环境中抗生素污染的缓解提供了一些新的见解。
