摘要： A continuous flow multistage aerobic wastewater sludge digestion system comprising at least two stages connected in series, each stage comprising one or more covered tanks, tank segments or compartments, each having an enclosed separate gas headspace, wherein the gas headspaces of each stage are connected in a specified sequence that may be identical to or different from the staging sequence followed by the sludge liquid. An oxygen containing gas stream, such as air or an oxygen enriched gas stream, is supplied to the headspace of each stage, and a means for aerating the sludge in one or more of the tanks, tank segments or compartments is provided to enhance the transfer of oxygen from the gas headspace into the sludge liquid for use by bacteria in digestion of the sludge. At least one stage of the sludge digestion system is operated at a thermophilic temperature above 50 °C and the flow of oxygen containing gas through the system can be cocurrent, countercurrent, or a mixture of both with respect to the flow of the liquid. Preferred embodiments of the invention include the use of this aerobic digestion system prior to anaerobic digestion.

摘要： A surface aeration impeller (54) for use in a biochemical oxidation tank (22) . The impeller is rotatable about an axis perpendicular to the static liquid surface (37). The impeller has a plurality of blades (2) mounted on the underside of a disc or disclike surface (1). Each blade (2) has a multi-faceted or curved geometry ranging from vertical at the point of attachment to the disc to partially inclined at the bottom. The blades are spaced circumferentially about the axis (3) and are disposed at acute angles to radial lines from the axis of rotation of the impeller. The lower portions (7) of the blades, which are inclined but non-vertical, are positioned at or below the static liquid surface. When the impeller is rotated, the lower portion (7) pumps the liquid up onto the vertical portion (6) of the blades where the liquid is discharged into a spray umbrella (53, 55, 57) in a direction upwardly and outwardly away from the impeller. The design of the reinvention produces substantially higher oxygen transfer efficiency and overall liquid pumping rate than prior art designs and is particularly useful in the aeration of sewage an other wastewater.

摘要： The invention is an improved surface aeration impeller for use in a liquid filled tank which particularly increases the surface turbulence and the entrainment of gas into the liquid surface. The impeller is an axial floor impeller and may be either a pitched blade turbine (PBT) or have airfoil shaped blades. In either case, the impeller has a portion which extends radially along an edge thereof which projects above the surface of the liquid being mixed in a vertical direction. The blades of the impeller are modified to include a top horizontal plate to lower the spray height of the liquid and an optional endcap, both of which can enhance and increase the standard aeration efficiency

摘要： A draft tube mixing system or reactor wherein the draft tube contains slots, perforations, or cut-out sections that allow cross flow of fluid through the draft tube wall. The perforations or slots can be practically any shape, however, simple geometric shapes such as rectangles and circles are preferred for ease of manufacture. The perforations or slots are typically arrayed in columns along a substantial section of the draft tube. In a preferred embodiment, the quantity and position of the perforations are such that a fluid filling the draft tube is capable of cross flow through the draft tube wall along substantially its entire length.
