摘　　要：针对矿化垃圾在填埋场甲烷气体控制的应用,研究了利用矿化垃圾富集和培养甲烷氧化菌的方法和条件优化。实验结果表明:矿化垃圾一般经过14 d的富集培养可对甲烷产生明显的氧化效果;矿化垃圾和改进的NMS培养液配比在(0.5g^2g)∶100 mL范围,都能取得较好的甲烷氧化菌培养效果,在此范围内高的矿化垃圾加入量有利于甲烷氧化菌的培养;矿化垃圾加改进的NMS培养液培养甲烷氧化菌的启动时间在2 d以内,一般在2 d左右甲烷氧化率达到最大;pH值7~9范围内,甲烷氧化菌的培养效果较好。Methods of enrichment and cultivation of methanotrophs from aged refuse were studied in this paper, and cultivation optimization of methanotrophs was investigated. Experiment Results indicated： aged refuse showed obvious oxidation capacity of methane after being enriehed for 14 days; the advantageous ratios of aged refuse and improved NMS culture medium for methanotrophs cultivation were proved between 0.5g：100mL and 2g：100mL the appropriate pH value for methanotrophs cultivation is 7---9; in this experiment, start-up time of methanotrophs cultivation was within 2 clays, and peak value of methane oxidation rate in methanotrophs cultivating appeared around the second day.
