Abstract
There were developed activators of interphase transport (AIPT) of oxygen, acting by a mechanism of rise in frequency of surface renewal of liquid’s shear layer, examined their efficiency in relation to mass transfer enhancement of O2 in the system gas-liquid. There was demonstrated that with decreasing of wettability and particles size of AIPT their ability to mass transfer enhancement O2 in the system of gas-liquid is increased. There was showed that the most effective AIPT is quartz particles, modified by polyvinylchloride (SiC2/PVC). There were identified optimal in relation to mass transfer enhancement of O2concentration of SiC2/PVC in aqueous phase and hydrodynamic conditions of mass-exchanging process conduction. There was determined that introduction of SiC2/PVC into cultural liquid of phenol-oxidizing bacteria allows to increase average velocity of phenol biodegradation by 1.3 times.
