摘　　要：采用超声-絮凝沉降相结合的方法对富营养化污水进行处理,探讨了超声-絮凝沉降法对富营养化污水的处理效果.结果表明:超声-絮凝沉降水处理技术较直接絮凝沉降或单独超声处理在去除总氮(TN)、总磷(TP)以及降低化学需氧量(COD)、生化需氧量(BOD)和浊度方面的效率分别提高了16.19%、12.71%、9.1%、20%、18.3%.With the development of industrial and agricultural production and people＇s living standards, there is a large number of various types of wastewater that caused serious pollution with nitrogen and phosphorus. The water of Dianchi lake was treated by Ultrasound - floceulation in this study. The results shows that Ultrasound -flocculation sedimentation is better than direct floceulation sedimentation in removing the total phosphorus, total nitrogen and reducing COD, BOD and turbidity respectively increased 16. 19% , 12.71% , 9. 1% , 20%, 18.3%.
