Biological wastewater treatment has developed for more than 100 years, and new concepts about future wastewater treatment have been put forward worldwide. Environmental biotechnology is still the key contributor for wastewater management. However, these biotechnologies are facing challenges due to stringent discharging standards and the removal of emerging pollutants. Here, a new concept of microbial niche nexus sustaining biological wastewater treatment was proposed, which can achieve the efficient removal of known and unknown pollutants through tuning microbial niches to accommodate diverse microbial communities. Microbial niche nexus could be applied to solve emerging challenges besides infrastructure construction. In addition, the co-enrichment of r/K-strategists and the establishment of microenvironments with substrate gradients could be adopted for the design and operation of biological wastewater treatment processes. Finally, future development and perspectives were presented through aspects of microbial enrichment, microbial function and metabolism identification, system design and operation control, and new technology development and application.

微生物生态位维持生物废水处理

生物废水处理已经发展了100多年,全球范围内提出了有关未来废水处理的新概念。环境生物技术仍然是废水管理的关键因素。然而,由于严格的排放标准和新兴污染物的去除,这些生物技术正面临挑战。在此,提出了维持生物废水处理的微生物生态位关系的新概念,该概念可以通过调整微生物生态位以适应各种微生物群落来有效去除已知和未知的污染物。除基础设施建设外,微生物生态位联系还可用于解决新出现的挑战。此外,r / K-战略家的共同富集和具有基质梯度的微环境的建立可用于生物废水处理工艺的设计和操作。最后,通过微生物富集,微生物功能和代谢识别,系统设计和运行控制以及新技术的开发和应用等方面,提出了未来的发展和展望。
