【摘要】：为有效控制富营养化水体中的藻类,研制了一种浮游式太阳能超声除藻装置。该装置将太阳能转化为电能作为超声的能源来源,利用超声波技术进行除藻和抑藻,能源自给、节能环保;装置在水体表面的自动浮游扩大了其作用面积;较小的吃水深度有助于装置对水体表层藻类的去除,有效抑制了水华的发生。采用该装置对模拟的含藻水体和实际的含藻湖泊水体进行了除藻抑藻试验,考查了该装置的控藻效果。结果表明:超声辐照频率和辐照功率密度越大,对藻类的即时去除率越大,试验中最大即时去除率可达40%;该装置能长期抑制藻细胞的分裂增殖;作用时间越长,除藻效果越好,实际含藻湖泊水处理60 min后藻类的去除率可达80%以上。
[Abstract]:In order to effectively control algae in eutrophication water, a solar energy ultrasonic removal device was developed. The device converts solar energy into electric energy as the energy source of ultrasonic, uses ultrasonic technology to remove algae and suppress algae, energy is self-sufficient, energy saving and environmental protection, the automatic floating of the device on the surface of water body expands its working area. A small draught depth is helpful to remove algae from the surface of the water body and effectively inhibits the occurrence of Shui Hua. In this paper, the algal control effect of the simulated algae-containing water body and the actual algae-containing lake water was investigated. The results showed that the higher the frequency and power density of ultrasound irradiation, the greater the immediate removal rate of algae, and the maximum immediate removal rate of algae reached 40% in the experiment, the device could inhibit the cell division and proliferation for a long time, and the longer the time, the better the effect of algae removal. The algal removal rate of algae-containing lake can reach more than 80% after 60 min treatment.
