摘要
A mass transfer system for decontaminating a contaminated liquid or gas stream. The system includes a container with a liquid inlet, a liquid outlet, a gas inlet and a gas outlet. The container is adapted to channel a liquid stream from the liquid inlet to the liquid outlet. The vessel is also adapted to channel a gas stream from the gas inlet to the gas outlet. At least one grid is mounted within the container and is positioned within the gas and liquid streams. The grid has a plurality of apertures formed therein which are adapted to disperse the gas flow as it passes through the grid. The dispersion of the gas flow generates a fluidized bed within the container. The grid is preferably parabolic in shape. A light assembly is mounted on the container and has a light emitting unit positioned so as to emit light into the container. The light irradiates at least one of the streams flowing therein. The configuration of the system is designed to cause the mixture of the gas stream and liquid streams to become turbulent, thereby increasing the liquid surface area. The light emitting unit is positioned so as to irradiate the two turbulent fluid flows so as to catalyze a chemical reaction. In one embodiment, an oxidant is added to one of the streams which, when irradiated by the ultraviolet light, produces hydroxyl radicals which chemically react with the contaminants in the stream.
