城市固废的热固液气化生耦合模型
THMCB coupled modeling in municipal solid waste
摘要
Abstract
The anaerobic degradation model for municipal solid waste ( MSW) is developed to study the influence of temperature on the biochemical degradation process in MSW. The existing first-order dynamic equation of biochemical degradation is improved to take the temperature into consideration by introducing a temperature dependent coefficient for both hydrolysis and methanogenesis process. With the numerical simulation program OGS, the impacts of temperature on the degradation proces-ses of cellulose, total sugar, protein and fat are analyzed, and also the hydrolysis and methanogene-sis processes at different temperature are investigated. The thermo-hydro-mechanical-chemical-bio-logical ( THMCB ) coupled model is calibrated by a pilot-scale experiment of MSW to reveal the effect of temperature in multi-field coupling. The results show that in the temperature range of 10 to 45 ℃, the biological degradation process can be significantly affected by temperature.关键词
