Abstract

The invention discloses a method for pretreating wastewater obtained from antibiotic production. The method comprises the following steps: adding a solid base to wastewater obtained from antibiotic production, and hydrolyzing the residual antibiotics in the wastewater obtained from antibiotic production under the action of the solid base. The method provided by the invention has high antibiotic degradation efficiency and low antibiotic residue, and the biological toxicity of the wastewater obtained from antibiotic production is significantly reduced. The antibiotic wastewater pretreated by the method provided by the invention can be directly subjected to the subsequent biochemical treatment. The method provided by the invention can completely remove the antibiotics in the antibiotic wastewater, reduce the inhibition of the high concentration antibiotics to microorganisms, reduce the difficulty of the subsequent biochemical treatment of the antibiotic wastewater, and reduce the production of drug-resistant bacteria and drug-resistant genes in the subsequent biochemical treatment.

Description

technical field [0001] The invention relates to a method for harmless treatment of waste in the pharmaceutical industry, in particular to a method for harmless treatment of waste liquid after producing antibiotics through fermentation, and belongs to the field of liquid waste treatment. Background technique [0002] Antibiotic pharmaceutical production wastewater is mainly high-concentration organic wastewater produced in the separation, extraction, refining and purification sections, such as crystallization liquid, waste mother liquor, etc., as well as washing wastewater from seed tanks, fermentation tanks, and cooling water from fermentation tanks. High-concentration organic wastewater with high pollution load, high toxicity, and strong antibacterial properties mainly comes from waste fermentation liquid or synthetic waste liquid after raw material extraction in the antibiotic production process. This type of wastewater, especially fermented antibiotic pharmaceutical waste...
