摘要	The anaerobic co-digestion of biomass waste, a promising process of reusing resources, is capable of improving methane production. However, the characteristics and composition of fermenting raw material negatively influence the efficiency of methane production. Optimization experiments were systematically performed in this study through anaerobic co-digestion with urea-ammoniated rice straw (UARS) and food waste (FW) as co-substrates. Anaerobic co-digestion of UARS and FW in biogas production under mesophilic conditions (35 A degrees C) was investigated in a 1 L enclosed triangular flask with a total organic load of 6 g volatile solids (VS)/L. The optimal mixing ratio of UARS to FW was close to 1:3, and the methane yield increasing by 8.83% compared with the sole substrate. Furthermore, based on the optimization ratio, supplementation of cobalt (Co) and nickel (Ni) on co-digestion were significantly superior to that of a single element. Additionally, kinetic analysis indicated that trace element remarkably facilitated the reaction rate of co-digestion. Noteworthy, the addition of Co, Ni, and the combination of Co and Ni achieved very significant (p < 0.01) improvement of 6.45, 8.36, and 13.65%. Meanwhile, Ni was substantially promoted the removal rate of VS, enhanced the operational stability of co-digestion and increased the methane content significantly.
