摘要： The invention relates to a stirred tank reactor for gas-liquid mass transfer in a slurry. The reactor includes a reactor tank (1) having a first volume (V1), a drive shaft (2) that extends vertically in the reactor tank, a motor (3) for rotating the drive shaft (2), a main impeller (4) which is a downward pumping axial flow impeller attached to the drive shaft (2) to create a main flow pattern in the reactor tank, and a gas inlet (5) arranged to supply gas into the reactor tank (1) to be dispersed to the liquid. The reactor includes a mechanical gas sparging apparatus (6) comprising a dispersion chamber (7) having a second volume (V2) which is substantially smaller than the first volume (V1) of the reactor tank (1), the dispersion chamber being arranged coaxial with the drive shaft (2), and the gas inlet (5) being arranged to feed gas into the dispersion chamber (7), and mixing means (8, 9, 10, 11, 12) arranged within the dispersion chamber (7) for mixing the gas into liquid by dispersing the gas to fine bubbles before the bubbles enter the main flow pattern. The mixing power per unit volume inside the dispersion chamber (7) is significantly larger than the mixing power elsewhere in the reactor.

摘要： An activated sludge wastewater treatment method is provided. The disclosed method includes: receiving a stream of wastewater into a mixed liquor in an uncovered activated sludge basin; introducing high purity oxygen to the mixed liquor in the activated sludge basin to produce euoxic conditions (i.e. a dissolved oxygen level in the range of between about 5 mg to 15 mg) in the activated sludge basin; passing a portion of the mixed liquor in the activated sludge basin through a clarifier to separate activated sludge and produce an effluent stream and an activated sludge stream; and recycling a portion of the activated sludge stream to the activated sludge basin to produce a mixed liquor having a solids loading of between about 3000 mg and about 10000 mg of suspended solids per liter of mixed liquor and a solids retention time of between about 7 days and 40 days.

摘要： An apparatus for the treatment of faeces, includes a tank (200) for housing faeces that has been subjected to treatment. There is a process vessel (202) in which the faeces is treated and which is located inside the tank (200) having an inlet (204) for feeding faeces into the process vessel (202). A rotary device (300) is provided for stirring the faeces in the process vessel (202) and for introducing oxygen into the faeces, which is operable in two modes of operation at different speeds of rotation. A partitioning member (212) separates the interior of the process vessel in a lower (216) and an upper (218) portion, while at the same time allowing communication between the lower and upper portions. The rotary device (300) is arranged to at least cause a suction of material mainly from the lower compartment in a first mode of operation and into the rotary device.

摘要： An apparatus for mixing gas and liquid is disclosed. The apparatus can comprise a draft tube having a gas conduit, a liquid inlet and a gas-liquid outlet, an impeller rotatably mounted within the draft tube. The gas can be entrained into the liquid by rotation of an impeller having relatively high angular velocity, which generates relatively low axial velocity of the liquid and relatively low angular velocity of the liquid. Floats may support the impeller and the impeller may have means for maximizing aeration of the liquid.

摘要： The invention relates to a method for the leaching of solid matter from a sludge with the aid of a gas containing oxygen, whereby the solid matter of the sludge is recirculated in a tall reactor equipped with a central pipe in the centre of the reactor and a double-action mixer located in the vicinity of the lower edge of the central pipe. A flow is formed with the aid of the mixer which sucks the sludge from the central pipe downward, and a gas to be conducted into the sludge in the bottom part of the reactor is dispersed in the form of small bubbles into the sludge outside the central pipe and the flow direction of the sludge is turned upwards in the outer casing of the reactor.
