Effect of Ultrasonic Energy Density of Ultrasonic Sludge Hydrolysis

Abstract:

Regard the added soluble chemical oxygen demand value (SCOD), TN, TP, VFA as the evaluation index, study the hydrolysis effect of different ultrasonic intensity of sewage sludge. The results show that: with the energy density of 0.75W/L, 1.5W/L, 3W/L after ultrasonic treatment of sludge, SCOD than the original clay increased a lot. Hydrolysis of five days later, having little difference of SCOD concentration in the sludge, and the 0.75W/L SCOD reached the peak, indicating little sound energy density difference of SCOD in sludge, and the low energy density effected better, while the concentration of TN, TP, VFA were increased with the increase of the energy density.
