摘 要: 为处理瓦斯的生物反应器选择填料,以甲烷(0~30%)空气混合气为研究对象,采用实验室规模生物填料塔,对活性炭、陶粒、塑料球及陶瓷鲍尔环挂膜性能进行比较。结果表明:陶瓷鲍尔环以适宜的比表面积、粒径及密度,其作为填料的反应器有较大的甲烷处理能力,较适合作为处理瓦斯的生物反应器填料。以鲍尔环作填料的反应器挂膜约25 d,甲烷去除效率达85%以上。
关 键 词: 微生物学;甲烷氧化细菌;生物滴滤塔;瓦斯;填料;生物膜

Abstract: For bio-oxidizing methane (with concentration 0~30% ) in coal mine gas with a biotrickling filter, four kinds of packing materials, such as activated carbons, filtration porcelain balls, plastic balls and ceramic Pall rings, were studied in the biofilter. The results indicate that the biotrickling filter with the ceramic Pall rings has the biggest capability to oxidize methane with its proper specific surface area, grain diameter and density, and is the most optimum one as the packing material for the biofilter to oxidize methane in coal mine gas. Based on this, the form-film time is 25 d, and the methane removal efficiency is 85%.
