Abstract:
Nowadays, the discharge of wastewater is a global concern due to the damage caused to human and environmental health. Wastewater treatment has progressed to provide environmentally and economically sustainable technologies. The biological treatment of wastewater is one of the fundamental bases of this field, and the employment of new technologies based on granular biofilm systems is demonstrating success in tackling the environmental issues derived from the discharge of wastewater. The granular-conforming microorganisms must be evaluated as functional entities because their activities and functions for removing pollutants are interconnected with the surrounding microbiota. The deep knowledge of microbial communities allows for the improvement in system operation, as the proliferation of microorganisms in charge of metabolic roles could be modified by adjustments to operational conditions. This is why engineering must consider the intrinsic microbiological aspects of biological wastewater treatment systems to obtain the most effective performance. This review provides an extensive view of the microbial ecology of biological wastewater treatment technologies based on granular biofilms for mitigating water pollution.
摘要:
如今,由于对人类和环境健康造成的损害,废水的排放是全球关注的问题。废水处理已取得进展,以提供环境和经济上可持续的技术。废水的生物处理是该领域的基础之一,基于颗粒生物膜系统的新技术的应用证明了在解决废水排放引起的环境问题方面的成功。必须将符合颗粒的微生物作为功能实体进行评估,因为它们去除污染物的活动和功能与周围的微生物群相互关联。对微生物群落的深入了解可以改善系统操作,因为负责代谢作用的微生物的增殖可以通过调整操作条件来改变。这就是为什么工程必须考虑生物废水处理系统的内在微生物方面,以获得最有效的性能。本文综述了基于颗粒生物膜的生物废水处理技术的微生物生态学,以减轻水污染。
