生物强化技术对移动床生物膜反应器启动过程中挂膜的影响

Influence on biofilm culturing in start-up stage of moving-bed biofilm reactor using bioaugmentation

分析了移动床生物膜反应器(MBBR)的工艺原理及目前研究存在的缺陷,提出MBBR的挂膜过程对反应器的启动时间、生物相及废水处理效果有重要的影响。生物强化技术可以增强对特定污染物的降解能力,改善原有生物处理体系对难降解有机物的去除效能。在简介生物强化技术作用机制及影响因素的基础上,探讨将生物强化技术应用于MBBR启动过程中的必要性和可能性,对提高污水处理能力具有一定的参考价值,可以带来良好的经济和环境效益。

The process principles and current research gaps of moving-bed biofilm reactor （MBBR） are briefly reviewed. It is pro- posed that its biofilm culturing affected start-up time, microorganism and wastewater treating efficiency. Bioaugmentaion can enhance the biodegradability of specific pollutants and improve the detoxication efficiency of biological treatment system. Considering mechanism and influencing factors of bioaugmentaion, it is both possible and necessary to apply bioaugmentaion in the start-up of MBBR. It is anticipated that this paper could provide useful guidance for the wastewater treatment capacity and provide economic and environmental benefits.
