| 摘 要： | 研究了扫频脉冲磁场对电厂循环冷却水中异养菌的影响,并对灭活关键因素进行了分析。实验结果表明,脉冲磁场对电厂循环冷却水中的异养菌有灭活作用。灭活率对频率和输出电压具有选择性,并且随着作用时间和温度的升高而升高。在扫频范围100～1 000Hz、输出电压3 V、单次作用时间为15 s,温度45℃时,异养菌灭活率可达78.8...

| Abstract: | The effect of sweep pulsed magnetic field on heterotrophic bacteria of power plant circulating cooling water was studied and the inactivation key factors were analyzed.It was found that pulsed magnetic field has an inactivated role in heterotrophic bacteria.The efficiency depends on the frequency and output voltage.The inactivated rate of magnetic field is increased with the increasing of the temperature and the single magnetic treatment time.With the sweep pulse magnetic field 100~1 000 Hz,the single magne... |
