文摘
- •
CeO2 NPs (20 mg/L) had a notable toxicity effect on P removal in SBBR system.
- •
The deteriorated SPRR was caused by the inhibited key enzyme activity (PPX).
- •
The decreased SPUR was caused by the bacterial community shifts.
- •
Ce ions converting and excess ROS generation are related toxicity mechanisms.
