【摘要】：通過建立厭氧降解模型研究了溫度對城市固廢中生化降解過程的影響,對已有的生化降解反應速率一級動力方程進行了修正,通過加入溫度影響系數(shù)考慮溫度的影響.基于OGS軟件,通過數(shù)值計算分析了溫度對城市固廢中纖維素、總糖、蛋白質(zhì)和脂肪組分的降解過程的影響,并研究了不同溫度下的水解與甲烷化過程.將大型模型槽試驗數(shù)據(jù)與數(shù)值計算結(jié)果進行對比,揭示了溫度在多場耦合作用中的影響.結(jié)果表明,在10~45℃溫度范圍內(nèi),溫度會顯著影響水解與甲烷化進程的反應速率.
[Abstract]:The effect of temperature on the biodegradation process of municipal solid waste was studied by establishing an anaerobic degradation model. The first order dynamic equation of the reaction rate of biodegradation was modified, and the influence of temperature was considered by adding the influence coefficient of temperature. Based on OGS software, the effects of temperature on the degradation of cellulose, total sugar, protein and fat components in municipal solid waste were analyzed by numerical calculation, and the hydrolysis and methanation processes at different temperatures were studied. The effect of temperature on multi-field coupling is revealed by comparing the experimental data of large model tank with the results of numerical calculation. The results show that the reaction rate of hydrolysis and methanation is significantly affected by the temperature of 1045 鈩，
