摘　　要：农业工业废物的厌氧共消化是通过沼气生产来稳定残留物的一种有前途的选择。这项研究考虑了牛瘤胃含量,皮革制革雕刻脂肪和活性污泥清除的混合物。对单个废物和废物混合物进行了生物降解性测试。通过使用固体出口数据调整化学计量系数来校准模型,并使用实验甲烷流量数据推导出动力学常数。动力学常数在大约四个停留时间内翻倍,这表明生物量已经适应了环境。anaerobic co digestion of agricultural and industrial wastes is a promising choice to stabilize residues through biogas production.This study considered a mixture of rumen content of cattle,leather carving fat and activated sludge removal.The biodegradability of single waste and waste mixture was tested.The model was calibrated by adjusting the stoichiometric coefficient with the solid outlet data,and the kinetic constants were derived from the experimental methane flow data.The kinetic constant doubled in about four residence times,indicating that biomass has adapted to the environment.
