文摘
- •
High-rate NH3-N and TN removal is achieved with a novel NUA–DAS biofilter.
- •
The AOB and NOB community structures in DAS are time dependent.
- •
The NOB community structures of both media are stable despite depth variation.
- •
Nitrosomonas, Nitrosovibrio and Nitrobacter are the dominant genera in substrate.
- •
The AOB and NOB activities from DAS are negatively correlated with Eff. NO3-N.
