Abstract
In order to develop an alternative denitrification system for purification of leachate from a municipal waste landfill, a laboratory experiment was carried out. Denitrification performance using alternative carbon resources in place of methanol was experimentally investigated in a laboratory tank. The carbon sources under investigation were hydrogen feeding agents, beer lees and solidified food oil. Hydrogen feeding agents and solidified food oil showed higher denitrification performance than the beer lees. The water quality model was verified by comparing the analytical solutions with the laboratory data using hydrogen feeding agents as carbon source. Time-dependent behaviors of every water quality component observed in the experiment were very well reproduced by the model. The analysis showed that the hydrogen feeding agent was found to be a very promising material for efficiently removing nitrogen from seriously contaminated leachate.
