    摘要： A wastewater treatment system including an aeration unit, a contact tank, a dissolved air flotation unit, and a biological treatment unit is disclosed. A method of retrofitting a wastewater treatment system by providing an aeration unit and fluidly connecting the aeration unit to the wastewater treatment system is also disclosed. A method of treating wastewater including aerating wastewater with oxygen, combining the aerated wastewater with activated sludge, floating biosolids from the activated wastewater, and biologically treating the effluent is also disclosed. The method optionally includes combining the floated biosolids with the aerated wastewater and/or activated wastewater. A method of facilitating treatment of high solids content wastewater is also disclosed.

    摘要： A method and system for treating wastewater is disclosed. In one embodiment the method includes introducing the wastewater into an aerated anoxic treatment unit, flowing an oxygen containing gas into the wastewater in the aerated anoxic treatment unit at a first flow rate, measuring a concentration of a nitrogen species in the wastewater in the aerated anoxic treatment unit, comparing the measured concentration of the nitrogen species to a target nitrogen species concentration, adjusting the flow of the oxygen containing gas into the wastewater in the aerated anoxic treatment unit to a second flow rate in response to a difference in the nitrogen species and the target nitrogen species concentrations, and maintaining the second flow rate for a time period sufficient for the wastewater to be treated in the aerated anoxic treatment unit and form an anoxically treated liquid having a reduced concentration of the nitrogen species.
