摘要
针对水体富营养化问题,研究超声波技术在不同功率、频率和超声时间下对铜绿微囊藻生长的抑制效果.结果表明,采用40 kHz,180 W的超声波,4 min为最佳超声辐照时间,可以显著降低铜绿微囊藻浓度,并且生长速度大大减缓.随着超声波功率的增加,抑藻效果有所增加,但有饱和的趋势.
In order to control cyanobacterial bloom in eutrophic water,the ultrasonic inhibition of alage was studied including different influencing factors,for example working power,frequency and time.The results confirmed that ultrasound can inhibit the growth of alage under the frequency of 40 kHz,the working power of 180 W and the duration time was 4 min.With the irradiation time extend,the effect trends to saturation.
