| 摘 要： | 以生活垃圾中COD溶出量为研究参数,试验研究了厌氧分步生物反应器系统和渗滤液直接回灌填埋场中的有机物降解规律与产甲烷特征.结果表明:厌氧分步生物反应器系统可显著促进生活垃圾及渗滤液中有机污染物的降解,加速填埋垃圾稳定化,其COD溶出总量与填埋时间的对数呈极显著的线性相关性.厌氧分步生物反应器中产甲烷反应器的产气量占总产气量的80%,甲烷含量55%～69%,较适容积COD负荷为6.5～7.5g/(L·d).

| Abstract: | Through analyzing and detecting the leaching pollutant (COD) in two bioreactors, anaerobic phased solid digester system and leachate direct-recirculating landfill, the changing rule of municipal solid waste and the characteristics of methanogenesis were studied. The results showed that anaerobic phased solid digester system accelerated the process of degrading municipal solid waste and stabilizing landfill site. The relationship between the leaching pollutant (COD) and refuse age was logarithmic linear correlation. More than 80% of biogas in volume occured in the methanogenisis bioreactor, the methane content in which was 55%-69%. The preferable volumetric COD loading rate of the methanogenisis bioreactor was 6.5-7.5 g/(L x d). |
