脉冲磁场对电厂循环冷却水中异养菌的灭活
Inactivation of heterotrophic bacteria in circulation cooling water system of power plant by pulsed magnetic field
摘要
Abstract
In order to control the harm caused by microbial growth in circulation cooling water systems,the inactivation of heterotrophic bacteria was investigated with the pulsed magnetic fields generated by DC-pulse generator combining with coil windings.Analyses for key factors of sterilization were carried out.The experimental results revealed that the pulsed magnetic fields have effects on inactivation of heterotrophic bacteria in the circulation cooling water system.The inactivation rates take selectivity for the frequency and output voltage.The inactivation rates increase with the increasing of temperature and time duration for each pulse.When the sweep frequency of pulsed magnetic field ranges from 10 to 1 000 Hz,the output voltage is 3 V,and the time duration for each pulse is 15 s,the inactivation rate is 78.8%.关键词
