Abstract

Landfill cell microbial carbon metabolism is not only organically influenced by the impact of landfill unit, but also closely related to the levels of landfill unit nitrogen.In this paper, we regard the landfill layer which is landfill in the surrounding black soil of Jilin Agricultural University as the research subjects, and we use laboratory experiments to comparative and study four kinds of nitrogen treatment ( natural statecarbon nitrogen ratio which is not adjusted, carbon and nitrogen ratio of 5: 1, carbon nitrogen ratio 20: 1 carbon nitrogen ratio: 50: 1)which are used to collect samples periodically.Using MPN measured the number of microorganisms of the unit of landfill and studying different carbon nitrogen ratio ratio of landfill unit ammonifiers affect the activity of denitrifying bacteria.Experimental results show:(1)Different carbon nitrogen ratio has different influence onthe number of denitrifying bacteri and,ammonifiers in he unit of the landfill.The number of ammonifiers, nitrobacteria and denitrifying bacteria is large of low carbon nitrogen ratio landfill,but high carbon nitrogen ratio is opposite.(2)Over time, different carbon nitrogen ratio changed the number of ammonifiers, nitrobacteria and denitrifying bacteria of the unit of the landfill which showed the trend of the first increase and then decrease.From this,we know the number of ammonifiers, nitrobacteria and denitrifying bacteria of the unit of the landfill is related to the ratio of carbon and nitrogen of the unit of the landfill.
