文摘
- •
Partial nitritation (PN) was fast started up in MBR within 19 days.
- •
The free ammonia overwhelmingly restrained the activity of NOB.
- •
Suitable feed was generated by PN with the optimal DO of 0.8–0.9 mg/L.
- •
Nitrosospira sp. YKU corresponded to implement ammonium oxidation.
- •
The MBR promises potential merit to implement one-stage nitritation and anmmox.
