Microscopy and Molecular Methods to Advance Performance and Design of Hybrid Biofilm Technology

开发新技术以满足当今废水处理挑战的需求导致了创新混合废水处理技术的设计。混合移动床生物膜反应器（MBBR）和曝气生物滤池（BAF）技术是将移动床生物膜反应器（MBBR）和上流式曝气生物滤池（BAF）技术的优点结合到一个混合系统中。特别是，混合MBBR-BAF已被设想为将消耗易于降解的进水碳的异养菌群与自养氨去除菌群分开。此外，杂交系统也被认为可以减轻BAF培养基上过度异养生长的不利影响。本研究计划的科学方法是分离关键操作和设计参数对系统性能的影响，以及对MBBR-BAF混合技术双重介质上生物膜和微生物群落特征的影响。

The need to develop new technologies that meet the wastewater treatment challenges of today has led to the design of innovative hybrid wastewater treatment technologies. The hybrid moving bed biofilm reactor (MBBR) and biological aerated filter (BAF) technology has been conceived to combine the advantages of the MBBR with an upflow BAF technology into a single hybrid system. In particular, the hybrid MBBR-BAF has been conceived to separate the heterotrophic population that consumes the readily degradable influent carbon from the autotrophic, ammonia removal population. Further, the hybrid system has also been conceived to mitigate the adverse effects of excessive heterotrophic growth on BAF media. The scientific approach of this research program is to isolate the impact of critical operational and design parameters on not only the performance of the system but also on the characteristics of the biofilm and the microbial communities on the dual media of the MBBR-BAF hybrid technology.
