【摘要】：通过建立厌氧降解模型研究了温度对城市固废中生化降解过程的影响,对已有的生化降解反应速率一级动力方程进行了修正,通过加入温度影响系数考虑温度的影响.基于OGS软件,通过数值计算分析了温度对城市固废中纤维素、总糖、蛋白质和脂肪组分的降解过程的影响,并研究了不同温度下的水解与甲烷化过程.将大型模型槽试验数据与数值计算结果进行对比,揭示了温度在多场耦合作用中的影响.结果表明,在10~45℃温度范围内,温度会显著影响水解与甲烷化进程的反应速率.
[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，
