1. Experimental purpose and principle:
The three-phase biological fluidized bed is a three-phase fluidized bed in which gas, liquid and solid react directly in the fluidized bed, without any oxygenation equipment or film removal equipment. The biofilm on the surface of the carrier relies on the stirring effect of the gas to cause intense friction between particles and fall off. The oxygenation methods include decompression release of *r oxygenation and jet aeration oxygenation. Since a small amount of carrier may be taken out of the bed sometimes, there is usually a carrier (including sludge) reflux in the process.
