Avaliação da eficiência das lagoas de tratamento do aterro municipal do Município de Francisco Beltrão

Abstract

Many environmental problems are found in Brazil , and many of them occur due to the rapid growth of the productive sectors and the consequent generation of solid waste. It is necessary to the proper disposal of these wastes, the most commonly used form, landfills. This practice, however, requires a high range of environmental control measures, being among them, the concern with the treatment of the leachate produced in the decomposition of the waste process. In this sense, the present work aimed to evaluate the efficacy of treatment of leachate from municipal landfill Francisco Beltran, Parana. For this, we determined three distinct points within the treatment of leachate from the landfill to collect samples for analysis system that followed. We analyzed the following physicochemical parameters: BOD, COD, total nitrogen, ammonia nitrogen, phosphorus, settleable solids and pH. The analyzes were carried out from November 2013 to February 2014, totaling three samplings. The results obtained from the analyzes showed differences as the working efficiency when presented the results of analyzes with the relevant laws.
