Short-term aerobic in SITU stabilization of municipal landfills: Laboratory tests

Ślęzak R., Krzystek L., Ledakowicz S.

Environment Protection Engineering

2009

Vol. 35, nr 3

81-92

The simulation of the in situ aerobic stabilization of waste was carried out in laboratory scale Iysimeters for a short period of time. In leachates, BOD5, COD, VFA, N-NH4, TKN and pH were assayed and in outlet gas the concentrations of methane, oxygen and carbon dioxide were determined. Whilst aerating waste, one could observe a decrease of organic load in leachates and lack of methane emission. After finished short-term aeration an increase in leachates indices occurred and methane in outlet gas from lysimeter appeared. In subsequent days after finished aeration one could observe a decrease in the indices of leachates and further production of methane.
