| 摘 要： | 基于生活垃圾填埋的室内模拟实验,通过4种不同工况下垃圾表面沉降规律的分析,研究了表面沉降对填埋场加速稳定化进程的指示作用.结果表明,垃圾稳定化进程中,表面沉降量S随时间相继呈线性、幂函数和双曲线分段变化,可在宏观上表征垃圾填埋场的稳定化进程及生物反应器填埋技术对稳定化进程的加速作用.在此基础上,将垃圾填埋场稳定化进程划分为3段:不稳定段,S27%.

| Abstract: | Based on the indoor-simulation test of MSW landfill,the macroscopic indication of surface settlement to landfill stabilization-accelerated process were analyzed through analyzing settlement law under four different operation modes.The result displayed that surface settlement(S) showed linear,power function and hyperbolic-type subsection variation successively in waste stabilization process.Thus,surface settlement could indicate landfill stabilization process and reflect accelerating effect of bioreactor lan... |
