Experimental Study of Sludge Treatment Using Ultrasonic Technology in Low Power Density

摘要：

This paper deals with municipal wastewater sludge,which is treated using ultrasonic technology with the power density of 0.014W(ml)-1,0.025 W(ml)-1,0.031 W(ml)-1 and 0.05 W(ml)-1.With the mentioned levels,the sludge has been treated on retention times ranging from 0 minute to 60 minutes.The result of this study shows that the dissolving percentage of SCOD can exceed 10％ after the sludge was treated about 45 minutes.At the same time,the concentration of ammonia nitrogen dropped to 5 mg L-1.
