Embodiment 1

[0056] A method of activating the antibiotic sulfate removing the hydrochloride using a waste lithium battery, specifically, using a catalyst to remove the hydrochloride left hydrochloride, including the following steps: Catalyst (CM-550, CM-650, CM- 750, CM-850 and CO 3 O 4 40 mg of each addition to 100 mL, 10 mg / L hydrochloride (LFX) solution (the pH of the solution was 4.65), magnetic force for 30 minutes, to achieve the adsorption equilibrium, 0.05 mmol Overdulfate (PMS) Degradation reaction for 60 minutes to complete the treatment of antibiotics in the water.

[0057] With no catalyst as a control group, only a mono-mononullate (PMS) is added, and the other conditions are the same.

[0058] In this Example 1, the prepared method for catalyst (CM-550, CM-650, CM-750, and CM-850), including the steps of:

[0059] (1) After discharge (low concentration NaCl brine soaked in 5 hours, the natural air dry) is removed, dismantled (disassemble the battery in the fume hood, separatin...

Abstract

The invention discloses a method for activating permonosulfate to remove antibiotics in water by using a catalyst prepared from a waste lithium battery. In the removal of antibiotics, the catalyst is prepared from waste lithium batteries by calcination, and the catalyst contains LiCoO 2 and Co 3 o 4 . The method of the present invention can achieve efficient degradation of antibiotics in water by mixing heterogeneous catalysts and permonosulfate prepared from waste lithium batteries as raw materials with water containing antibiotics for degradation reaction, and has the advantages of simple operation, low treatment cost, It has the advantages of wide application range, high processing efficiency, good processing effect, strong reusability, and environmental friendliness, and has good application value and application prospect.

Description

Technical field [0001] The present invention belongs to a lithium battery recovery cycle utilization and a high-grade oxidation treatment in the environmental contaminant, and is related to the method of removing antibiotics in the water, and is,,,,,,,,,,, . Background technique [0002] With the continuous development of medicine and the increase in medical supplies such as drugs, more and more pharmaceutical facts come to life. Among the drugs produced, antibiotics are widely used to treat bacterial infections, but in its production process, due to improper management of the discharged antibiotic wastewater, the wastewater is discharged into the river lake, and then pollutants in the water The accumulation of the environment is harmful to aquatic organism. For example, hydrochloride left levofloxacin is a typical fluoroquinolone antibiotic, which is widely used in the treatment of various respiratory, urethral diseases and skin infections. Its widely leads to increased bacteria...
