SBR Washing System for contaminated soils, SBR Washing Apparatus for contaminated soils and SBR Washing Method for contaminated soils

摘要

PURPOSE: A sequencing batch type polluted soil washing system using floatation, a sequencing batch type polluted soil washing apparatus, and a sequencing batch type polluted soil washing method are provided to improve the efficiency of operations by successively operating a plurality of sequencing batch type polluted soil washing units with a pre-determined interval. CONSTITUTION: A sequencing batch type polluted soil washing system using floatation includes at least two sequencing batch type polluted soil washing units(100), a flux adjusting bath(200), a water treatment unit(300), and a controller(400). The washing units implement operations and washing processes with a cycle containing a polluted soil and washing water introducing unit, a high pressure aeration-based mixture, a settling unit, a wastewater draining unit, and a washed soil exhausting unit. The flux adjusting bath is connected to the washing units. Wastewater from the washing units is introduced into the flux adjusting bath. The water treatment unit purifies the wastewater. The controller differently controls the operational time of the washing units. The washing units are successively operated by the controlling unit.
