Abstract

Sustainable wastewater treatment is essential for attaining clean water and sanitation, aligning with UN Sustainable Development Goals. Wastewater treatment plants (WWTPs) have utilized environmental microbiomes in biological treatment processes in this effort for over a century. However, the inherent complexity and redundancy of microbial communities, and emerging chemical and biological contaminants, challenge the biotechnology applications. Over the past decades, understanding and utilization of microbial energy metabolism and interaction relationships have revolutionized the biological system. In this review, we discuss how microbiome regulation strategies are being used to generate actionable performance for low-carbon pollutant removal and resource recovery in WWTPs. The engineering application cases also highlight the real feasibility and promising prospects of the microbiome regulation approaches. In conclusion, we recommend identifying environmental risks associated with chemical and biological contaminants transformation as a prerequisite. We propose the integration of gene editing and enzyme design to precisely regulate microbiomes for the synergistic control of both chemical and biological risks. Additionally, the development of integrated technologies and engineering equipment is crucial in addressing the ongoing water crisis. This review advocates for the innovation of conventional wastewater treatment biotechnology to ensure sustainable wastewater treatment.

可持续废水处理的微生物组调控。
可持续废水处理是实现清洁水源和卫生设施的当务之急,也是联合国可持续发展目标之一。一个多世纪以来,污水处理厂(WWTPs)一直利用生物处理过程中的环境微生物组来实现这一目标。然而,微生物群落固有的复杂性和冗余性,以及新出现的化学和生物污染物,对生物技术的应用提出了挑战。在过去的几十年中,对微生物能量代谢和相互作用关系的理解和利用已经彻底改变了生物系统。在本综述中,我们将讨论如何利用微生物组调控策略为污水处理厂的低碳污染物去除和资源回收创造可操作的性能。工程应用案例也凸显了微生物组调控方法的实际可行性和广阔前景。总之,我们主张以识别与化学和生物污染物转化相关的环境风险为前提。我们建议将基因编辑与酶设计相结合,精确调控微生物组,以协同控制化学和生物风险。此外,开发集成技术和工程设备对于解决当前的水危机也势在必行。本综述提倡对传统废水处理生物技术进行创新,以确保可持续的废水处理。
