Description

technical field

[0001] The invention belongs to the field of wastewater treatment, and in particular relates to a method for treating wastewater generated in an antibiotic production process. Background technique

[0002] At present, there are more than 300 enterprises producing antibiotics in my country, producing 70 varieties of antibiotics accounting for 20% to 30% of the world's output. The output is increasing year by year, and it has become one of the major antibiotic preparation countries in the world. The antibiotic production process includes microbial fermentation, filtration, extraction, crystallization, refining, refining and other processes. The wastewater produced has a high concentration of organic matter (biochemical oxygen demand is usually 5000-80000mg / l), a high concentration of suspended solids (500-25000mg / L ), complex components (intermediate metabolites, surfactants, high concentrations of acids, alkalis and organic solvents), presence of biologically ...
