Evaluation of toxicity of anaerobic and aerobic microorganisms of landfilm leach and effluent produced by the fenton process
In this work, the toxicity of anaerobic and aerobic microorganisms from the Fenton process effluent applied to the treatment of leachate from the sanitary landfill (LAS) was studied. The leachate used was collected at the metropolitan landfill in the city of João Pessoa (PB). After collection, the s...
