Abstract

The application of the present invention belongs to the technical field of wastewater treatment, and specifically discloses a method for reducing the biological toxicity of antibiotic wastewater through acid-base treatment, comprising the following steps: (1) taking wastewater containing antibiotics, adding strong acid to the wastewater and stirring for 2-3 hours; (2) adding alkali to the wastewater in step (1) to adjust the pH to 6-7; (3) extracting the wastewater in step (2), and concentrating the extracted wastewater containing antibiotics to obtain isolates containing antibiotics; ( 4) Adding a strong base to the isolate in step (3) to inactivate the antibiotics. The invention is mainly used for treating waste water and solves the problem that the waste water contains antibiotics and easily pollutes the environment.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and specifically discloses a method for reducing the biotoxicity of antibiotic wastewater through acid-base treatment. Background technique [0002] Antibiotics are widely used in the prevention and treatment of human and animal infectious diseases and as growth promoters in animals. With the increasing use of antibiotics worldwide, antibiotics are making great contributions to the development of human and animal health. [0003] With the increasing use of antibiotics, it has brought about increasingly serious environmental problems. During the production of antibiotics, unused antibiotics are dissolved in wastewater, which is discharged into soil and water bodies. After antibiotics enter soil and water bodies, they will cause potential hazards to public health and the aquatic environment, such as aquatic toxicity, resistance of pathogenic bacteria, endocrine disrupting activity, a...
