The effect of chemical oxygen demand (COD) and volatile solids (VS) on subsequent methane (CH4) production during anaerobic digestion (AD) of organic fraction of municipal solid waste (OFMSW) was studied in a laboratory-scale digester. The experiment was performed in 2L anaerobic digester under different experimental conditions using different input mass co-digested with inoculum and organic loading rate (OLR) for 27days at 38±2°C. Three digesters (digesters 1, 2 and 3) were operated at initial loading of 5.1, 10.4 and 15.2g/L CODS per batch which were reduced to 77.9% and 84.2%, respectively. Cumulative biogas productions were 9.3, 10.7 and 17.7L in which CH4 yields were 84.3, 101.0 and 168.4mL/gVS removal in digesters 1, 2, and 3, respectively. The observed COD removal was found to be influenced on variation in CH4 production. Co-efficient of determination (R(2)) was 0.67 and 0.74 in digesters 1 and 2, respectively.
研究了化学需氧量（COD）和挥发性固体（VS）对城市固体废物有机部分（OFMSW）厌氧消化（AD）过程中随后甲烷（CH4）产生的影响。在实验室规模的消化器中，在不同的实验条件下，使用不同的接种物和有机负荷率（OLR）进行了 27 天的 2L 厌氧消化实验，温度为 38±2°C。三个消化器（消化器 1、2 和 3）的初始加载量分别为 5.1、10.4 和 15.2g/L COD/批，分别减少到 77.9%和 84.2%。在消化器 1、2 和 3 中，累积沼气产量分别为 9.3、10.7 和 17.7L，其中 CH4 产率分别为 84.3、101.0 和 168.4mL/gVS 去除率。观察到的 COD 去除率似乎受到 CH4 产量变化的影响。在消化器 1 和 2 中，决定系数（R(2)）分别为 0.67 和 0.74。
