Treatment of Lake-type Raw Water by Ultrasonic and Photocatalytic Oxidization Process

摘要

The lake-type raw water was treated in a photocatalytic oxidization reactor. The experiment was carried out using ultrasonic under the condition of flow rate 10L/h, the padding packing compares 2/5, UV lamp 30W, non-additional chemicals, pH 7.35. Moremore, the raw water also was treated by ultrasonic/photocatalytic oxidization integrated process under the same control conditions. The results indicate that, after ultrasonic/photocatalytic oxidization process for 36 hours, the average removal of COD_(Mn), TP, Chl-a and OD_(560) were 25.3%, 30.1%, 98.6% and 88.1%, respectively.
