Abstract

In Brazil, the disposal of solid residues largely occurs in open areas, without appropriate treatment, exceeding soils natural capacity of minimizing the charge of organic pollutants. The problem caused by incorrect disposal of solid waste is minimized by installing landfills, which reduce environmental impacts and the damages to communities and public health. Generated leachates in landfills are composed by liquids came from external sources (superficial draining systems, rains, ground water tables and nascents) besides liquids resulted of organic residues decomposition. Their characteristics can vary according to the type of solid waste, depth and decomposition degree and also due to the type of operations and landfill's age. Complexity of leachates requires flexibility in their treatments and adopted techniques to a determined landfill will not necessarily be applicable to others. The present study intends to contribute with information about treatability of landfills in country part of São Paulo State, and also to establish correlation among analyzed parameters, becoming possible planning each type of treatment directed to each landfill. Leachates will be collected in landfills of a totality of six cities. The experiment will be carried in 30 °C, in biological sequencing batch filter. Characteristics of physic-chemical and biological parameters of affluents and effluents will be followed in each cycle of batch and a temporal profile with three points will be realized through the four months of filter's operation.
