文摘
- •
Dewatered sewage sludge (DSS) was co-digested with pig manure (PM).
- •
Mixture of PM and DSS produced a higher methane yield than digesting DSS alone.
- •
Anaerobic co-digestion of PM with DSS exhibited a shorter hydraulic retention time.
- •
Digestates from mixture of PM and DSS showed high pH and low VFA/TIC ratio.
- •
Modified Gompertz model shows better fit to the results than the first order model.
