摘要:
A swing-type submersible floating aerator, comprising a gas-ring compressor, a base, a pipe, a support tube, a swing device and a driving device, wherein the base is disposed between the gas-ring compressor and the support tube, the base is disposed at the center of the swing device, and the driving device drives the swing device to rotate. The swing-type submersible floating aerator is capable of rotating 360 degrees in a clockwise or a counterclockwise direction, and push-flow and aeration can be performed in any direction.

Air grid systems for distributing a gas within treatment systems such as underdrain filters and contact clarifiers is disclosed. The air grid is supported from above so that it can be lowered into position and thus modified or repaired. Additionally, this feature permits retrofitting an air grid into an existing system, such as an underdrain filter, in which the bed of media overlies the underdrain is not upset by the installation. Thus, methods of installing or retrofitting air grid systems are also disclosed. In another aspect of the present invention, the air grid is comprised of an air manifold connected to air laterals by a spreader conduit that is inserted through a smooth bore in the walls of the manifold, thereby providing a simple and easy to manufacture structure that avoids problems found in prior art components.
摘要:
A configuration of an aeration chamber for an activated-sludge treatment plant includes an elongated, hydraulic plug-flow aeration chamber with a floor having a sloped portion and a level portion. The level portion, which acts as a collection area for the activated sludge, is adjacent the air diffusers of the aeration chamber at the point of maximum turbulence within the chamber. By using the force of gravity to assist in returning the activated sludge to the point of maximum turbulence, the aeration chamber of the present invention is able to process sewage in a more efficient manner.
摘要:
A horizontal mixing aerator rides on an upright beam member for submersion in a body of water such as an equalization basin, oxidation ditch, or sludge holding tank. The aerator employs a submersible mixer motor driving a propeller which in one embodiment is mounted on the beam member by a slidable bracket for height adjustment. The bracket is also swingably mounted to the beam member for adjustment of the vertical plane angle. Because the beam member is also mounted for rotation, substantially any attitude or position of the mixer can be selected for creating an efficient flow pattern within the body of water. Air or fluid injection can also be provided by the use of alternate embodiments.
摘要:
A swing diffuser apparatus for gas diffuser systems for liquid treatment is disclosed in which an array of diffusers (50) is movable between a deeply submerged, essentially horizontal operating position, a shallowly submerged, essentially horizontal operating position, and a fully exposed, substantially upright position at the edge of the container for the liquid. An articulated hanger arm linkage (22, 24, 26, 30, 32, 52, 54) rotates the array to achieve these positions as the linkage folds and unfolds.
摘要:
A diffuser assembly of the general type for use in a municipal sewage treatment plant is of plastic and/or resin construction and includes spaced parallel or dual hanger pipes between the two rotary joints. The hoist arm extends between these hanger pipes to reach the lift joint. Opposed detent blocks between and engaging the dual pipes cooperate with a steady bracket into which the assembly is locked with a toggle action.

The fixed joint of the swing diffuser assembly includes a tee connected to the gas supply line. The swing joint includes a second tee. The upper leg of the swing diffuser comprises dual parallel pipes having elbows turnable in the ends of the tees. The dual pipes together comprise the upper leg and with the two joints provide the structural rigidity which particularly allows the joints to be constructed of molded plastic and the pipe of reinforced resin.
摘要:
A plurality of high density polyethylene or polyvinylchloride, plastic, diffuser elements are supported on a horizontal distribution header which is in turn supportedly suspended within a waste treatment basin from at least two vertically oriented elongated members. The elongated members are each provided with a hinged joint so that the diffusers can be rotated about the hinged joint to a location out of the basin for cleaning or replacement.
