| Sumario: | At present, the large volume of solid waste generated in large cities and the best way to pack and treat their by-products has been much discussed. Landfills are known to receive large amounts and types of urban solid waste. As a result, the leachate produced in the decomposition of these residues has peculiar characteristics and great chemical complexity. It is also known for its high turbidity, characteristic color and odor, as well as the high recalcitrance of its constituents. This work aims to present some techniques used in the treatment of landfill leachate and to evaluate its performance by means of the application of some of these techniques. The leachate was collected at the Gericino landfill (at Bangu in the periphery of Rio de Janeiro City). The types of treatment that will be addressed in this work involve coagulation/flocculation processes, activated carbon adsorption and membrane filtration. The coagulation batch tests were performed as a pre-treatment step, followed by the adsorption process in coal. The behavior of the filtered samples after pre-treatment was also verified. At the end of the assays, the chemical oxygen demand (COD) was up to 90% lower, absorbance was removed by 97% and turbidity was almost completely absent. |
