摘要: In this study, anaerobic digestion (AD) performance and system stability of CaO-ultrasonic pretreated sludge were investigated. The dewatered activated sludge (DAS) at four TS concentrations (4, 6, 8 and 10%) was pretreated by CaO-ultrasonic pretreatment. The results showed that CaO-ultrasonic pretreatment achieved better effect compared to the control, which was at same the TS concentrations, the CaO-ultrasonic pretreated DAS produced 4.24–44.99% higher cumulative biomethane production (CBP) than the control. The …
