摘要： A system and method for the treatment and reduction of sludge via ozonation in a wastewater treatment process is disclosed. The sludge treatment system comprises: a sludge ozonation reactor coupled to an activated sludge treatment basin and adapted to receive a liquid stream of sludge containing biosolids from the activated sludge treatment basin. The sludge treatment system also includes an ozone-enriched gas injection system operatively coupled to the reactor and adapted to inject ozone-enriched gas into the liquid stream at or upstream of the sludge ozonation reactor. The sludge ozonation reactor is configured to allow effective gas-liquid contacting between the ozone-enriched gas and the liquid stream so as to oxidize the biosolids in the liquid stream and initiate bacterial cell lysis thereby reducing the biosolids. Upon reduction of the biosolids, the liquid stream is returned via a return line to the activated sludge basin or other discharge point.

摘要： A system and method for oxygenating an aerobic sludge digester is provided. The disclosed embodiments include an aerobic sludge digester tank or vessel having a mechanically agitated contactor disposed therein, an oxygen injection subsystem adapted to inject oxygen into the digester tank proximate the mechanically agitated contactor. The embodiments of the mechanically agitated contactor include an agitator or impeller disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator or impeller is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then dispersed into the aerobic digester. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of oxygen dissolution into the sludge and greater bubble residence time.

摘要： A system and method for mixing high viscous liquids with gas is provided. The disclosed embodiments include a reactor or mixing vessel having a draft tube disposed therein, a gas injection subsystem adapted to inject gas into the reactor or mixing vessel proximate the entrance of the draft tube. The embodiments also include an agitator disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then ejected into the reactor or mixing vessel. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of gas dissolution into the high viscous liquid within the draft tube and greater bubble residence time within the high viscous liquid.
