Abstract

The Municipal Treatment Station of Americana, São Paulo, Brazil, manages 400 L s–1 of effluent, from domestic and textile origin, which produces an average of 20 t of sludge per day. The degradation of the effluent and sludge by cyanobacteria, by fungus Pleurotus, and anaerobic system was evaluated after an activated sludge treatment. The detoxification was appraised with three bioassays comprising the cnidarian Hydra attenuata, the algae Selenastrum capricornutum and lettuce (Lactuca sativa) seeds. All the microorganisms were able to degrade and detoxify the effluent. The strains of Pleurotus were able to decolorized the sludge, however the toxicity increased. The three strains produced high amounts of manganese-peroxidase and laccase in the presence of the effluent or sludge. The anaerobic/aerobic treatment was the most efficient for degradation of the effluent and reducing its toxicity.
