摘要： The invention provides a fluid treatment apparatus including a fluid bed reactor. The fluid bed reactor includes a flow distribution system having a flow distributor for introducing untreated fluid into the reactor. The untreated fluid is introduced at a flow rate sufficient to generate an upflow velocity within the reactor that fluidizes the media bed within the reactor. The flow distribution system also includes a backflow prevention apparatus for supplying an auxiliary fluid to the flow distributer in the event flow of untreated fluid to the flow distributor is interrupted. The auxiliary fluid flushes the flow distributor while the media bed defluidizes to prevent the media bed from backing up into the flow distributor as it settles to the bottom of the reactor.
