Abstract

The invention discloses a catalyst for rapidly activating persulfate to oxidize and degrade antibiotic waste water and its preparation and application method. The catalyst is a bismuth ferrite composite catalyst co-modified with magnetic silver and black phosphorus quantum dots. The preparation method is as follows: silver nitrate and iron The bismuth acid precursor is mixed and dissolved in water, and the sodium hydroxide solution is added drop by drop. After stirring evenly, black phosphorus quantum dots are added and stirred; then transferred to a hydrothermal reactor for synthesis; after the reaction, the synthesized material is washed and dried . The invention has the advantages of excellent degradation effect, recyclability and the like.

Description

A catalyst for rapidly activating persulfate oxidative degradation of antibiotic wastewater and its preparation and application method technical field The invention belongs to the technical field of waste water treatment, relate to a kind of degrading antibiotic waste water catalyst, relate in particular to a kind of A catalyst for rapidly activating persulfate oxidative degradation of antibiotic wastewater and its preparation and application. Background technique Antibiotic-containing wastewater mainly comes from industries such as livestock and poultry breeding wastewater, medical wastewater and pharmaceutical wastewater. To include macrolides, tetracyclines, sulfonamides, quinolones, beta-lactams, aminoglycosides, chloramphenicol, polypeptides Eight types of compounds, such pollutants can enter the human body in various ways, have a certain damage to the liver and kidneys and other organs, and also It can cause allergic reactions to damage the nervous system, an...
