摘要

描述了一个简单的稳态附着生长厌氧发酵动力学数学模型。该模型考虑了单产甲烷培养遵循莫诺生长动力学。该模型考虑了进水生物降解性和挥发性固体浓度、温度和水力滞留时间的影响，并预测了甲烷体积产率和挥发性固体减少。它与传统的悬浮生长反应器模型的不同之处在于，它基于水力流量和进水挥发性固体浓度，明确考虑了反应器系统中的细菌浓度。利用多孔培养基和固体培养基附着式发酵罐的数据验证了该模型。

A Monod-based model of attached-growth anaerobic fermenters

A simple mathematical model of steady-state attached-growth anaerobic fermenter kinetics is described. The model considers a single methanogenic culture following Monod growth kinetics. The model accounts for effects of influent biodegradability and volatile solids concentration, temperature and hydraulic retention time, and predicts volumetric methane productivity and volatile solids reduction. It is distinguished from conventional suspended-growth reactor models by its explicit consideration of bacterial concentration in the reactor system, based on hydraulic flow and influent volatile solids concentration. The model was validated using data from both porous- and solid-media attached-growth fermenters.
