SIMULATION OF AEROBIC STABILISATION OF MUNICIPAL LANDFILLS IN LYSIMETERS
Liliana Krzystek, Anna Zieleniewska, Stanisław Ledakowicz, H.-J. Kahle
ABSTRACT
Results of experimental studies of simulation of the aerobic stabilisation of municipal landfills in lysimeters are discussed in the paper. It was found that due to the aeration, intensive leachate circulation and enhancement of organic substance degradation by advanced oxidation processes (ozonation), waste bed stabilisation was reached in a very short time. After 20 days since the beginning of lysimeter aeration, a reduction of both nitrogen compounds (N-NH4+ by around 70%), and easily biodegradable organic substances (ca. 90%) was achieved.
Key words: lysimeters, landfills, aerobic stabilisation, leachates, ozonation.
