A STUDY ON INTERNAL-CIRCULATION THREE-PHASE BIO-FLUIDISED BED APPLIED IN MICRO-POLLUTED RESOURCE WATER PURIFYING

摘要

An Internal-circulation Three-phase Bio-fluidised Bed (ITFB) was tested for its performance in micro-polluted resource water purifying, with the treatment capacity of 192L/d. The result demonstrated that a high-quality effluent reached COD_(Mn) < 3mg/L. The system degraded above 60% of the influent COD. The construction of the reactor adjusted was be more packed and more efficient to fit the small-scale drinking water purifying station.
