| Abstract: | Municipal excess sludge dewatering is an important step of sludge treatment, the dewatering performance of the municipal excess sludge was characterized by the selected parameters, the influence of sound wave frequency, sound energy density, ultrasonic pretreatment time, pH value and some other factors on dewatering of municipal excess sludge pretreated by ultrasonic were analyzed, besides, the research status of using coupling process of ultrasonic and some other methods to improve sludge dewatering performance was discussed. The mechanism of sludge dewatering by ultrasonic was emphatically studied, and the prospect of the said process was expected. |
