Treating the Eutrophic Water by Ultrasonic – Flocculation Sedimentation

Article Preview

Abstract:

With the development of industrial production and the improvement people's living standards, all kinds of discharged wastewater cause serious pollution for nitrogen and phosphorus.In this study, the water of Dianchi lake was treated by Ultrasonic – flocculation. The results show ultrasound-flocculation sedimentation is better than only flocculation 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%.
