摘要

Improvements introduced in the imhoff tanks of primary treatment for the deposition of urban wastewater for transformation in secondary oxidation treatment, characterized essentially by installing in the imhoff tank the mechanical elements necessary for the introduction of pressurized air, for which the orifices of the tank's mouth are plugged, the rectangular holes are transformed into circular holes, attaching tubes that penetrate into the tank to a depth below the plane of the diffusers, introducing four sets of tubes inside the tank, composed of a vertical section and another horizontal, in which the air diffusers are located, through which the amount of air necessary to supply the precise oxygen and achieve oxidation is introduced into the liquid mass of the aeration tank.
