Embodiment 1

[0058] 1. Preparation of antibiotic simulated wastewater

[0059] Dissolve standard macrolide antibiotic spiramycin in ultrapure water to prepare spiramycin simulated wastewater, wherein the concentration of spiramycin simulated wastewater is 100mg / L, that is, every 1L of simulated wastewater contains 100mg spiramycin Vegetarian standard.

[0060] In the embodiment of the present invention, 100 mg of the standard substance of the antibiotic spiramycin was dissolved in 1 L of ultrapure water to prepare spiramycin simulated wastewater with a concentration of 100 mg / L, wherein the theoretical concentration of spiramycin was 100 mg / L.

[0061] 2. Adjust the pH value of antibiotic wastewater

[0062] Add the acidic pH regulator HCl to the spiramycin simulated wastewater to adjust the pH of the wastewater to 6.0;

[0063] The specific embodiment of the present invention part except adopting HCl to regulate the pH of antibiotic pharmaceutical wastewater, other acidic substances suc...

Embodiment 1A

[0073] In addition to adjusting the pH value of the antibiotic wastewater step to adjust the pH of the simulated wastewater to 3.0, the solid super acid SO 4 2- / TiO 2 Medium TiO 2 and SO 4 2- The weight portion proportioning is except 89:11, and all the other are identical with embodiment 1, and measurement result is as shown in table 1.

Abstract

The invention provides a pretreatment method capable of removing an antibiotic in antibiotic pharmaceutical wastewater and an antibiotic pharmaceutical wastewater treatment method. The pretreatment method comprises the steps of adding a solid acid to the antibiotic pharmaceutical wastewater and carrying out hydrolysis treatment on residual antibiotic in the antibiotic pharmaceutical wastewater. According to the method, the concentration of the antibiotic in the antibiotic pharmaceutical wastewater can be significantly reduced, an active functional group in an antibiotic molecule is hydrolyzed and destroyed, inhibition of the high-concentration antibiotic on microorganisms is reduced, the difficulty of subsequent biochemical wastewater treatment is reduced, drug-resistant bacteria and drug-resistant genes in subsequent biochemical treatment are reduced, and the treated antibiotic pharmaceutical wastewater can be connected to the subsequent biochemical treatment process for treatment.

Description

technical field [0001] The invention relates to the field of pharmaceutical wastewater treatment, in particular to a pretreatment method for removing antibiotics from fermented antibiotic pharmaceutical wastewater. Background technique [0002] Antibiotic pharmaceutical wastewater is a type of high-concentration organic wastewater with high pollution load, high toxicity, and strong antibacterial properties. It 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 wastewater, has a large amount of medium components or organic raw materials remaining, and has the characteristics of large water volume, high COD (10g / L-80g / L) and high TSS (0.5-2.5g / L) . Long-term operation experience at home and abroad proves that compared with physical and chemical technology, the antibiotic pharmaceutical wastewater treatment technology wi...
