Avaliação da redução da poluição do chorume tratado por processo fotoquímico

Resumo

This work was aimed at evaluating leachate pollution reduction in the sanitary landfill of Limeira-SP city through a photochemical treatment using UV/ H2O2 process. The treatment was accomplished in a Pyrex glass reactor of approximately 1.7 L (internal diameter: 100 mm, external diameter: 145 mm, total height:300 mm). The experiments were carried out through water refrigeration and internal recirculation system of the leachate. The best reduced values for environmental control parameters were: 46 % of total organic carbon (TOC), 93 % total of phenols and 97 % of ammoniacal nitrogen and 91% of leachate color reduction. These results were obtained through the following optimized experimental conditions: H2O2 35 mL added to the reactor in aliquots of 15 mL (starting), 10 mL (30 minutes), 10 mL (60 minutes), 45oC temperature, 400 Watts lamp and 90 minute treatment time.
