This study aims at investigating the effects of MSW incinerator fly ash (FA) and bottom ash (BA) on the anaerobic co-digestion of OFMSW with FA or BA. It also simulates the biogas production from various dosed and control bioreactors. Results showed that suitable ashes addition (FA/MSW 10 and 20 g L(-1) and BA/MSW 100 g L(-1)) could improve the MSW anaerobic digestion and enhance the biogas production rates. FA/MSW 20 g L(-1) bioreactor had the higher biogas production and rate implying the potential option for MSW anaerobic co-digestion. Modeling studies showed that exponential plot simulated better for FA/MSW 10 g L(-1) and control bioreactors while Gaussian plot was applicable for FA/MSW 20 g L(-1) one. Linear and exponential plot of descending limb both simulated better for BA/MSW 100 g L(-1) bioreactor. Modified Gompertz plot showed higher correlation of biogas accumulation than exponential rise to maximum plot for all bioreactors.
本研究旨在探讨城市生活垃圾焚烧飞灰（FA）和底灰（BA）对厨余垃圾与 FA 或 BA 进行厌氧共消化的影响。还模拟了各种投加和对照生物反应器的沼气产生情况。结果表明，适量的灰分添加（FA/MSW10 和 20g/L 和 BA/MSW100g/L）可以提高城市生活垃圾的厌氧消化效率，并提高沼气产生率。FA/MSW20g/L 生物反应器具有更高的沼气产量和产率，表明其是城市生活垃圾厌氧共消化的潜在选择。模型研究表明，指数图更适合 FA/MSW10g/L 和对照生物反应器，而高斯图适用于 FA/MSW20g/L。对于 BA/MSW100g/L 生物反应器，下降支的线性和指数图都能更好地模拟。与指数上升到最大图相比，改良的 Gompertz 图显示出所有生物反应器的沼气积累具有更高的相关性。
