机械生物处理(MBT)是一种有助于节约资源和减少对环境有害的排放的废物处理技术。利用MBT处理城市生活垃圾是环境岩土工程领域的研究热点。利用压缩渗透仪和大型垂直渗透仪对MBT垃圾进行了渗透试验，并考虑了颗粒大小的影响。在相同的压力和组分干质量(%)下，粒径较小的样品的渗透率较低。对数渗透率与干密度等变量之间的最佳拟合线为线性。随着干密度的增加或孔隙率的减小，颗粒较小的样品的渗透率下降幅度较大。材料的对数渗透率随平均粒径和孔隙率的增大而增大。在0~10、0~20、0~40 mm粒径范围内，其渗透率分别为10−10~10−5、10−8~10−4和10−5~10−3 m/S。分析了MBT垃圾与城市生活垃圾在渗透性方面的差异。将MBT填埋场的结果与前人的研究结果进行了比较，为MBT垃圾填埋场的渗透性分析提供参考。
Mechanical biological treatment (MBT) is a waste processing technology that helps conserve resources and reduce emissions harmful to the environment. The treatment of municipal solid waste (MSW) using MBT is a hot topic in environmental geotechnical engineering. Permeability tests were carried out on MBT waste using a compression and permeability combined apparatus and a large-scale vertical permeability apparatus taking the influence of particle size into consideration. The permeability of samples with smaller particle sizes was found to be lower for the same pressure and dry mass (%) of component. The best-fit line between the logarithmic permeability and variables such as the dry density was linear. As the dry density increased or the void ratio decreased, the permeability of samples with smaller particles decreased more. The logarithmic permeability increased with the increase in the average particle size and void ratio. The permeabilities of MBT waste corresponding to particle size ranges of 0–10, 0–20, and 0–40 mm were 10−10–10−5, 10−8–10−4, and 10−5–10−3 m/s, respectively. The difference between MBT waste and MSW was analyzed in terms of their permeability. The results of MBT waste were compared with those reported in previous studies to provide reference for the permeability analysis of MBT landfills.
