A study on the characterisic of start-up in an internal loop three-ph ase biofluidized bed
Abstract：The effects of airflow rate,hydraulic retention time,slud ge inoculation concentration and trace elements on biofilm formation on carrier surface in an internal loop three-phase biofluidized bed were studied.The resul t s show that 0.384L/min of airflow rate,shorter HRT(HRT<4h) and smaller inoculati on concentration can be beneficial to the rapid biofilm formation.The method of rapid clean-up of sludge can make the success of start-up of the reactor.The e ffect of trace elements of zinc and nickel on biofilm formation is smaller.
