Use of immobilized Yarrowia lipolytica for batch treatment of oily wastewater
|
Abstract:
High concentration oil and chemical oxygen demand(COD) wastewaters were degraded by immobilized Yarrowia lipolytica in the airlift bioreactor.Results showed that the degradation efficiencies of oil and COD were exceed 85% and 70%,respectively when immobilized cells were reused for nine times,while the concentrations of oil and COD in the wastewater were 2 000 mg/L and 3 000 mg/L,respectively and degradation time was six days in every reaction cycle.In addition,during biological treatment of oily and COD was...
