Analyze of the Density and Viscosity of Landfill Leachate in Different Temperatures

摘要

The landfill leachate contains o its composition, basically, a mixture of organic and inorganic substances, compounds in solution and in colloidal state, and several species of microorganisms [1]. The impact produced by leachate in the environment is directly related with their stage of decomposition. To understand it better, its's necessary to know the mechanisms governing the rheological behavior of the leachate. Because of this was done an experimental study to determine the behavior of the density and viscosity to leachate of Volta Redonda city Landfill. This process occurred at different concentrations in order to simulate the rainy period, when the leachate presents fewer concentration, and at different temperatures to demonstrate the seasons where temperature oscillations occurs. To determine the viscosity was used a capillary viscometer, and to determine the density was used an electronic densimeter. The results describe that the concentration of the leached alter the viscosity and density of the same, or a more concentrated leachate has higher density and higher viscosity. And both the density and viscosity decrease with increasing temperatures.
