| 摘 要： | 加速稳定化表征指标是生物反应器填埋技术评价的重要内容。通过垃圾填埋室内模拟实验,研究不同运行工况下垃圾挥发性固体(VS)、生物可降解物(BDM)、纤维素(C)和纤维素/木质素(C/L)等组分指标的动态变化规律及其对加速稳定化进程的指示作用,进而探寻各指标之间的相关性,进一步筛选确定垃圾填埋场加速稳定化进程的核心表征指标。结果表明,垃圾组分VS、BDM、C和C/L的衰减符合一级反应动力学,其动态变化能够较为灵敏地指示渗滤液回灌和通风供氧对垃圾稳定化的显著加速作用,可作为垃圾填埋场加速稳定化进程的表征指标。VS、BDM、C和C/L相互之间具有良好的正线性相关性。BDM和C/L适宜作为垃圾填埋场加速稳定化进程的核心表征指标。

| Abstract: | MSW landfill stabilization-accelerated indicator is the significant content of bioreactor technology assessment. Through indoor simulation experiment of MSW landfill, dynamic variation law and indicating function of volatile solid (VS), biodegradable matter (BDM), cellulose (C) and cellulose/lignin (C/L) of waste composition under different operation modes were investigated. The correlation of indicators was explored and core indicators for MSW landfill stabilization-accelerated process were ascertained finally. The results displayed that attenuation of VS, BDM, C and C/L corresponded with first order reaction kinetics and their dynamic variation could sensitively indicate the observable accelerating effect of leachate recirculation and ventilation on MSW stabilization, which could be the important indicators to demonstrate MSW landfill stabilization-accelerated process. There were nice positive linear correlations among VS, BDM, C and C/L. BDM and C/L were suitable to be core indicators. |
