摘要
研究了超声波功率,作用时间以及与次氯酸钠协调作用对工业用水杀菌消毒效果。结果表明:50 W的超声波对藻类叶绿素合成量的抑制率达到了68.75%;低频率超声波对水中微生物团聚体的机械分散性能好于高频率的超声波,超声波与次氯酸钠协同作用既可提高灭菌效果,又可减少75%杀菌剂的使用量。
This paper studied the influence factors of sterilization effect of industrial water, such as ultrasonic power and time, synergistic effect of sodium hypochlorite. The results indica- ted that the inhibition ratio on microalgae chlorophyll synthesis amount reached 68.75% by 50W ultrasonic; mechanical dispersion of microorganism aggregates of low frequency ultrasonic was better than that of high frequency ultrasonic ; The synergistic effect of ultrasonic and sodium hypochlorite could increase the sterilization effect and decrease the bactericide dosage by 75 %.
