英文摘要	The effects of the mixing ratio of excess sludge (ES) with chicken manure (CM) on methane yield and digestate dewaterability were investigated at thermophilic and mesophilic temperatures. Batch experiments were performed at five different volatile solid ratios (ES/CM). Compared with anaerobic digestion of ES alone, codigestion of ES with CM increased methane yield 82.4–123.1 mL g−1-VSadded (mesophilic) and 33.9–171.3 mL g−1-VSadded (thermophilic), respectively. The normalized capillary suction time (NCST) and TS of thickened digestate (3.09–8.29 s g−1-TS, 17.51 %–18.83 %) at mesophilic temperatures were superior to these (6.81–10.14 s g−1-TS, 16.66 %–18.30 %) at thermophilic temperatures. But the gap decreased with increasing CM proportion in the substrate. The results indicated that anaerobic codigestion of ES and CM at a proper mixing ratio (ES/CM = 1:1.5–2) could obtain a high methane yield and an adequate digestate dewaterability. © 2022
