| 摘 要： | 生物覆盖层甲烷氧化是填埋场甲烷减排的重要途径，覆盖层基质性能对其甲烷氧化能力影响较大。选用≤1mm堆肥物（1#基质）、≤1mm堆肥物＋陶粒（2^#基质）、≤1mm堆肥物＋陶粒（3#基质）、1～2mm堆肥物（4#基质）、2～3．2mm堆肥物（5#基质）等5种不同类型的生物覆盖层基质，在实验室内模拟研究填埋场生物覆盖层的甲烷生物氧化状况，旨在为筛选垃圾填埋场甲烷高效氧化的生物覆盖材料提供科学依据。试验结果表明：粒径对基质氧气传输能力的影响不明显；不同基质的甲烷氧化能力存在显著差异，纯堆肥物基质（1#、4#和5#基质）几乎没有甲烷氧化能力，堆肥物＋陶粒（1：1（v：v）的复合基质（2#、3#基质）的甲烷氧化效率高达100％。堆肥物一陶粒复合基质为甲烷氧化细菌营造了良好的环境，改善了生物覆盖层内的气体传输性能，是一种适宜的填埋场生物覆盖层基质材料。

| Abstract: | Methane oxidation of bio-cover is the main way of methane emission reduction in landfill.Matrix greatly affects methane oxidation capability of landfill cover.Four different matrixes were studied on its methane oxidation in simulative columns in order to select perfect bio-cover material of landfill.The results showed that particle size of materials hadn't obviously effect on transfer of oxygen;methane oxidation capability of different matrix is obviously different,some even haven't methane oxidation capabi... |
