| 摘 要： | 为加速填埋场的稳定化进程,采用传统的微生物学方法,从环境中经反复筛选及多次传代培养得到性能稳定的功能菌.根据功能菌的功能,组合成不同的功能菌群,通过研究各组功能菌群产酶的能力和对填埋场稳定化指标的影响,构建了加速填埋场稳定化进程的复合菌系.结果表明:在性能稳定的功能菌中,含9株纤维素降解菌,8株渗滤液化学需氧量COD(chemical oxygen demand)降解菌,7株絮凝剂产生菌;由所有菌株共同组成的功能菌群Ⅶ#的产酶能力最强,引入填埋场可有效加速填埋垃圾的生物降解,促进填埋场稳定化,使填埋垃圾有机质生物降解率、胡敏酸的百分含量和沉降率较未添加功能菌群对照组分别高26.23%、9.18%和10.01%.

| Abstract: | For accelerating the stabilization of landfill,functional strains were screened and sub-cultured repeatedly with traditional microbiological methods in surroundings.Then the screened strains were grouped and coded from I# to VII# based on the different functions of the strains.The compound flora used to accelerate the stabilization of landfill was constructed by analyzing zymogenic capacities and the effects on stability indices.The results show that the functional strains with stable performance includes 9... |
