| 摘 要： | 针对藻类在常规水处理过程中难以被有效去除的现状,采用超声预处理对太湖高藻水混凝过程进行强化.研究结果表明:在20mg/L的聚合氯化铝投加量条件下,采用功率为100W的超声预处理15s可强化混凝效果,有效去除90%以上藻细胞,降低沉后水浊度;低频条件下超声频率并非藻类去除效果的决定性因素;超声总能量和时间影响强化混凝效果,功率高于200W或处理时间长于30s会影响混凝效果.在过量条件下进行超声预处理会造成胞内物质及藻毒素的严重释放,实际应用中须合理确定其作用参数.

| Abstract: | Aimed at conventional removal of low algae,enhance dultrasonic coagulation treatment of high-algae water from Taihu lake were studied.The results show that: ultrasonic irradiation,with an aluminium polychloride dose of 20 mg/L,at 100 W for 15 s can significantly enhance the removal of algae(more than 90%) and the turbidity,the ultrasonic frequency was not a decisive factor for algae removal in low frequency range;ultrasonic dosage decides the effect of ultrasonic enhanced coagulation.High power(more than 20... |
