Method for treating antibiotic wastewater by using immobilized laccase

The invention discloses a method for treating antibiotic wastewater by using immobilized laccase. The method comprises the following steps: mixing the immobilized laccase, a mediator substance and theantibiotic wastewater for degrading treatment so as to complete degrading treatment on antibiotics in the wastewater, wherein the immobilized laccase takes mesoporous bentonite as a carrier, laccaseis fixed onto the mesoporous bentonite, and the mesoporous bentonite is prepared through subjecting bentonite, which serves as a raw material, to acid/base etching. According to the method disclosed by the invention, the antibiotics in the wastewater can be rapidly and efficiently degraded when the antibiotic wastewater is treated by using the immobilized laccase; and meanwhile, the immobilized laccase has better adaptability to environments, so that the immobilized laccase has a broader application environment compared with free laccase, has the advantages of simplicity, rapidness, high efficiency, low cost, no second
