| Abstract: | Excess sludge treatment and disposal is an important environmental issue at home and abroad.Disruption of excess sludge by ultrasound and ozone was investigated.Influence of different parameters was discussed including reaction time,ozone flux and ultrasonic power.Results indicated that when the ozone flux was 7 L/min,the efficiency of disruption was the best during ozonation along with SCOD,NH3-N,TN and TP at 40 min contact increasing by 586%,178%,522% and 1,781% respectively.When ultrasound was 800 W,the ... |
