APPARATUS PROVIDED WITH FLUIDIZED BED CRYSTALLIZER FOR TREATING WASTEWATER

摘要

AN APPARATUS PROVIDED WITH A FLUIDIZED BED CYSTALLIZER FOR TREATING WASTEWATER COMPRISES A REACTOR (4) FILLED WITH CARRIERS (22) AND POTABLE TAP WATER, A REAGENT INLET (3) CONNECTED TO THE REACTOR (4) FOR INTRODUCING REAGENT INTO THE REACTOR (4), AND A RECIRCULATION CONNECTED WITH THE REACTOR (4). THE WASTEWATER CAN BE INTRODUCED INTO THE REACTOR (4) THROUGH THE RECIRCULATION, A FIRST WASTEWATER PIPE (82) PROVIDED ON THE BOTTOM OF THE REACTOR (4), OR A SECOND WASTEWATER PIPE (88) EXTENDING FROM THE TOP TO THE BOTTOM OF THE REACTOR (4). THE WASTEWATER THEN FLOWS UPWARD TO FLUIDIZE THE CARRIERS (22). THE REAGENT CAN REACT WITH POLLUTANTS CONTAINED IN THE WASTEWATER TO FORM CRYSTALS ON THE FLUIDIZED CARRIERS (22). FINALLY, THE TREATED WASTEWATER IS DISCHARGED FROM THE TOP OF THE REACTOR (4).(FIG 1)
