摘要: This work presents results from a detailed characterization of landfill leachates different ages in major Brazilian city. consists determining the molecular size distribution and inert chemical oxygen demand (COD) biodegradability both aerobic anaerobic processes. Results show that leachate with high COD concentration has low biodegradability. A significant fraction is not characterized as protein, carbohydrate, or lipids, which reinforces hypothesis remaining was present all fractions (less than 1 kDa; between 10 100 greater kDa) refractory. These suggest such characteristics require treatment systems use physical-chemical processes pre- post-treatment step to biological
