Abstract

The invention relates to a method for degrading drug residue prednisone in waste water by utilizing irradiation. The method provided by the invention comprises that irradiation treatment is carried out on a waste water solution containing prednisone pollutant by adopting a certain dosage electron beam accelerator irradiation technology, so that prednisone in the waste water solution is decomposed. By adopting the method provided by the invention, the prednisone in the waste water solution can be quickly and effectively degraded by virtue of low dosage irradiation, so that the concentration of prednisone in the waste water solution can meet safety and emission standards; and the operation is easy, no toxicity is added, and no residual harm is done.

Description

technical field [0001] The invention belongs to the field of wastewater treatment and relates to a method for degrading drug residue prednisone in wastewater by using irradiation. Background technique [0002] Prednisone and its derivatives are a class of synthetic adrenal corticosteroids with high efficiency in anti-immune stress response. They have typical effects of glucocorticoids, such as anti-inflammatory effects and immune response suppression. Their anti-inflammatory effects are 4 times that of hydrocortisone, but only 80% of the mineralocorticoid effect. Prednisone has been used in clinical treatment of spinal cord injury since the 1960s. In recent years, after in-depth research by scholars from various countries, it is believed that it has various neuroprotective effects, including improving microcirculation, inhibiting lipid peroxidation, reducing cell Calcium influx, maintenance of neuronal excitability, etc. This drug has strong anti-inflammatory and anti-alle...
