摘要

Abstract

Ultrasonic airlift loop reactor (UALR) shows potential and wide application for wastewater treatment. In this paper the performance and efficiency of UALR in dimethoate degradation were presented. The effects of O

flow rate

ultrasonic intensity and initial concentration of dimethoate on degradation rate were investigated. UALR imposed a synergistic effect combining sonochemical merit with high O

transfer rate. The results showed that UALR not only increased degradation rate

but also was better than the simple sum of degradation by O

and ultrasound separately. Under the operation conditions of O

flow of 0.34 m

·h

-1

ultrasonic intensity 3.71 W·cm

-2

and initial concentration of dimethoate at 20 mg·L

-1

the degradation rate of dimethoate increased to 80%. UALR seems an advisable choice for treating organic wastewater and this process may have wide application prospect in industry.
