This study conducts a comprehensive comparative analysis of leachate treatment methods, specifically focusing on continuous aeration, discontinuous aeration, and a non-aerated control sample. The investigation centers on removing ammonia, nitrates, chemical oxygen demand (COD), and color over a defined experimental period. Results indicate that continuous aeration exhibits remarkable efficiency in ammonia elimination, achieving an impressive abatement rate of 97.6% after 41 days. Discontinuous aeration also proves effective, reducing ammoniacal nitrogen content by 95.4% over the same period. However, continuous aeration outperforms in eliminating this odor-causing element. For nitrates, aeration samples show higher concentrations than the non-aerated control, demonstrating a notable 35% reduction by day 41. In terms of COD, continuous aeration demonstrates superior efficacy despite a subsequent increase after day 35, potentially due to microbial hydrolysis. The non-aerated control achieves 100% COD removal after 21 days, but concentrations tend to rise after that. Regarding color, all methods exhibit a sharp decrease, with respective abatement rates of 54, 57, and 55% between the 6th and 41st experimental days. These findings underscore the significance of continuous aeration in leachate treatment, emphasizing the need for tailored approaches based on specific leachate components for effective waste management practices.
