Abstract

Landfill leach ate is one of the most contaminated wastewaters. Because of the widespread use of municipal landfills for final disposal of solid waste, there is an increasing concern over their public health and environmental hazards. In this study, the LANDFILL LEACH ATE of city of Shiraz was successfully treated using an ABR system of 4 compartments with a capacity of 64 litters volume and a hydraulic retention time of 4 days. COD removal efficiencies of 82.38, 85.19, 82.53, 82.22, and 80.12 per cent were achieved for organic loading rates (OLR) of 1.2, 2, 3, 5, and 7.75 kg COD/m3/day, respectively. Sampling and test results revealed that the highest activity of acid genesis bacteria belonged to the 1st compartment with the least amount of pH=6.54. It was shown that due to the formation of ammonia alkalinity in the reactor, there was a slight increase in the alkalinity of leach ate with the maximum effluent amount of 6291 mg/l (as CaCO3) in OLR=7.75 kg COD/m3/day. In this study, hydrodynamic characteristics and biological performance of an ANAEROBIC BAFFLED REACTOR (ABR) was also investigated. RESIDENCE TIME DISTRIBUTION (RTD) test with step input method was carried out on ABR. According to the graphs and theoretical model results, the number of CFSTRs was equal to the number of the ABR compartments (N=4).
