Influência das condições meteorológicas na biodegradação dos resíduos sólidos urbanos em Campina Grande-PB.

Abstract

In Brazil, several municipalities, municipal solid waste are disposed of in dumps, open and often burned, creating unsanitary conditions and creating an environment conducive to proliferation of vectors (flies, cockroaches, mosquitoes, rodents), polluting the soil , waterways and air, changing the quality of the elements that make up the biosphere (lithosphere, hydrosphere and atmosphere). One of the most widely used techniques is the provision in landfills due to its low cost and easy operation. In the projects is necessary to observe some features even before its implementation, such as weather conditions in the region where it should be built and appear as a determining factor in the analysis of various parameters governing the behavior of these landfills, as the generation, treatment, quality and production of leachate, the physical, chemical, biological, gas generation, and repression of temperature within the mass of waste. It is in this light that this study aims to analyze how weather conditions influence the behavior of municipal solid waste in an experimental cell and its effects on biodegradation processes in the city of Campina Grande in the state of Paraiba in Northeast Brazil and correlates parameters within and outside the cell. The research methodology was conducted in two stages: a general methodology and a specific methodology, such as collections of samples of municipal solid waste, laboratory tests and measurements "in situ" in the cell, as well as measurements carried out in the weather EMBRAPA weather station, then the data was written, validated and correlated by the statistic. Studies in experimental cell showed that: The weather conditions are crucial for the dynamics of degradation of municipal solid waste, there were also similarities in temperature with the temperature inside the cell it because there is no strict thermal insulation, however, the conditions weather did not stop the advance in the degradation process, but gave up quickly compared to other different situations, weather conditions in the Agreste region were extremely favorable to accelerate the biodegradation of waste in Experimental Cell and Water deficit exists in throughout the region in Campina Grande-PB can observe the low production of leachate and the meteorological data collected and studied, can be applied to studies on full-scale landfills, in regions with characteristics expressed as semi arid conditions real. The aim is to assist in decisions that work in projects related to environment and the construction of landfills in scale, becoming a case study for management and management of municipal solid waste in Paraiba.
