Problems solved by technology

②The organic components contained are complex and changeable, contain many heterocycles and refractory substances, have strong inhibition to microorganisms, high toxicity, deep color and high salt content
[0006] Chinese patent application 20071013952.2 discloses a clean production method for antibiotics, which includes the steps of fermentation liquid dilution and pretreatment-filtration-decolorization-alkaliization crystallization-secondary filtration, etc. The method uses membrane filtration, which leads to high operating costs and cumbersome operations. Inefficient operation of antibiotic industrial wastewater treatment
Each part of the combined process of this method is a relatively simple traditional process, and the water quality standard after treatment is low. It is not suitable for the treatment of pharmaceutical wastewater with complex components, nor can it meet the increasingly stringent environmental protection requirements.

Description

technical field [0001] The invention relates to a method for treating antibiotic pharmaceutical wastewater, in particular to a method for treating wastewater produced in the process of biological fermentation and chemical synthesis antibiotic pharmaceuticals, and belongs to the technical field of environmental protection. Background technique [0002] Antibiotics are a class of chemicals that inhibit or kill other microorganisms. In the environment, even trace amounts of antibiotics can form or enhance the resistance of pathogens in humans and animals, seriously threatening the function of the ecosystem. In recent years, antibiotics have been detected in water bodies such as sewage treatment plant effluent, surface water, and groundwater, which has become a serious environmental pollution problem. [0003] Antibiotic pharmaceutical wastewater is a type of high-concentration organic wastewater with high pollution load, high toxicity, and strong antibacterial properties. It m...
