Circulating-bed bioreactor made of quartz glass was used for phenol degradation under ultraviolet w ith 254nm wave2 length. Regularity of phenol degradation was respectively discussed and compared under photolysis by ultraviolet alone, biodegra2 dation by biofil m alone, and coup led ultraviolet and biofil m. Experi mental results indicated that the biofil m in the ceram ic m icro2 porous still had good biological activity under ultraviolet radiation even. The phenol degradation speed was

The phenol removal loading under the coup led p rocess was the highest among all three p rocesses.
