Experimental research on sterilization in a flowing O2 postdischarge reactor
Destruction processe of Escherichia coli(E.coil)had been analyzed in a O2 flowing postdischarge reactor where has high quantity of oxygen atoms and other charged particles.The germicidal effect was investigated as a function of the treatment time,the discharge power,the sample position and the concentration of organic pollutant.The microstructure of E.coli before and after sterilization were observed with digital microscope.The results showed that under the optimum treatment conditions of 100 W and 60 S,E.coli could be inactivated effectively within the distance of 0～40 cm from the center of induction coil.But the germicidal effect reduced rapidly with increasing the concentration of organic pollutant,namely,the influence of organic pollutant on germicidal effect was great.The digital microscope pictures indicated that the intense penetrating through the outer membrane of bacilli by the discharged particles with high energy in flowing O2 postdischarge reactor played a major role during the treatment process.
