摘要
WASTEWATER BIOLOGICAL TREATMENT PLANT WITH TWO ANAEROBIC DIGESTERS AND TREATMENT PROCESS consisting of a monitored system of double anaerobic reactor, the first with a fixed bed for the fixation of the acidogenic bacteria and the second with a fluidised bed for the fixation of the methanogenic bacteria with a capacity 1.5 times of the first reactor, in which the first Reactor by means of a suspension design at medium height of the fixed bed on a mesh plate supported by an inverse decantation wall, an inclined flat base and a pump and a recirculation conduit of water with matter in suspension linked to an alkaline doser, a pH meter and a computer programme, guarantees the flow of the spill with neutral pH and without heavy metals, to a second reactor, optimising the performance of the methanogenic bacterial biomass and reducing the Hydraulic Residence Time to 1-3 days.
