It illustrates microorganism control measures in bottle-packed pure drinking water production,introduces microorganism index control by ozone sterilization from the creation of ozone,its mixing with pure water,sterilization effect and its influential matters,which to give certain guidance for actual production.

The sterilization effect of high-intensity pulsed magnetic field (PMF) on bacteria was studied.

Using Escherichia coli as the object microorganism,the influence of different growth phase of Escherichia coli,magnetic field intensity,pulsed number of magnetic field and material temperature on sterilization effect was studied.
