Hydrolysis Rate of Solid Waste in Bioreactor Landfill
-
摘要: 在一级反应动力学基础上,建立了反映温度变化影响的生物反应器填埋场固相有机垃圾水解模型,通过 模拟实验对模型参数进行了估计,并对模型可靠性进行了检验.研究表明,生物反应器填埋场进入减速产甲烷阶 段后,环境温度较高时,较高的渗滤液回灌频率有利于固相有机垃圾的水解和填埋场的快速稳定;环境温度较低 时,应降低渗滤液回灌频率.Abstract: Based on the first-order kinetics, a hydrolysis dynamics model including the influence of temperature was set up for solid waste in bioreactor landfills. The parameters in the dynamics model were determined by simulation experiments and its reliability was verified. The research shows that a high leachate recirculation rate is favorable to the hydrolysis of solid waste and the rapid stabilization of solid waste in a bioreactor landfill under high temperature, while the leachate recirculation rate should be lowered under low temperature.
