The aim of the present work was to study and infer a full scale experience on co-digestion of 1000kg of FW (400kg cooked food waste and 600kg uncooked food waste) and 2000L of rice gruel (RG) on daily basis based on a high rate biomethanation technology called "Anaerobic gas lift reactor" (AGR). The pH of raw substrate was low (5.2-5.5) that resulted in rapid acidification phenomena with in 12h in the feed preparation tank that facilitated to obtain a lower hydraulic residence time (HRT) of 10days. At full load, AGR was fed with 245kg of total solids, 205kg of volatile solids (167kg of organic matter in terms of chemical oxygen demand) which resulted in the generation of biogas and bio manure of 140m/day and 110kg/day respectively. The produced biogas replaced 60-70kg of LPG per day.
本工作旨在研究并推断在基于称为“厌氧气升式反应器”（AGR）的高负荷生物甲烷化技术的基础上，每天协同消化 1000kg 厨余垃圾（400kg 熟厨余垃圾和 600kg 生厨余垃圾）和 2000L 米浆（RG）的全面经验。原料的 pH 值较低（5.2-5.5），这导致在进料制备罐中在 12 小时内迅速发生酸化现象，从而有利于获得 10 天的较低水力停留时间（HRT）。在满载时，AGR 进料 245kg 的总固体，205kg 的挥发性固体（以化学需氧量计的 167kg 有机物质），产生 140m³/天和 110kg/天的沼气和生物肥料。产生的沼气每天替代 60-70kg 的液化石油气。
