Abstract： |
The invention relates to a method for processing phenol-containing waste water by anaerobic-aerobic coupling biofluidized bed, firstly making the waste water enter in a regulating pondage and then enter in a biofluidized bed containing macroporous suspended carriers for aeration and degrading the waste water by the anaerobic-aerobic coupling biotreatment then draining the degraded waste water out of the biofluidized bed, placing still, draining upper-layer standard-reaching water, discharging a small part of the lower-layer water with deposited mud and returning the large part to the biofluidized bed for continuing taking part in the waste water processing process. And it implements coupling of anaerobic and aerobic biodegradations. |
