Embodiment 1

[0061] 1. Preparation of antibiotic simulated wastewater

[0062] Dissolve 100 mg of the standard substance of tetracycline antibiotic tetracycline hydrochloride in 1 L of ultrapure water to prepare tetracycline simulated wastewater with a concentration of tetracycline hydrochloride of 100 mg / L, wherein the theoretical concentration of tetracycline is 92 mg / L;

[0063] 2. Adjust the pH value of antibiotic wastewater

[0064] Add alkaline pH regulator NaOH to the tetracycline simulated wastewater to adjust the pH of the wastewater to 11.0;

[0065] Part of the specific embodiments of the present invention In addition to using NaOH to adjust the pH of antibiotic pharmaceutical wastewater to be alkaline, other alkaline substances such as KOH are applicable to the present invention.

[0066] Fermentation antibiotic pharmaceutical wastewater enters the adjustment tank after sedimentation and separation to adjust the pH of the wastewater to an appropriate value. There are great di...

Embodiment 2

[0073] Except that the pH value of the tetracycline simulated wastewater was adjusted to 11.0 in the step of "adjusting the pH value of antibiotic wastewater" and that no catalyst was added in the step of "hydrolysis treatment", the rest was the same as in Example 1. The results of sampling time interval, tetracycline concentration and wastewater titer are shown in Table 2.

[0075] time

[0076] 15min

Embodiment 3

[0078] 1. Preparation of antibiotic simulated wastewater

[0079] The preparation of tetracycline simulated wastewater is the same as in Example 1.

[0080] 2. Adjust the pH value of antibiotic wastewater

[0081] Add the acidic pH regulator HCl to the tetracycline simulated wastewater to adjust the pH of the wastewater to 5.0;

[0082]Part of the specific embodiment of the present invention is except adopting HCl to adjust the pH of antibiotic pharmaceutical wastewater to be acidic, other acidic substances such as H 2 SO 4 、HNO 3 etc. are applicable to the present invention.

[0083] 3. Hydrolysis treatment

[0084] Put 500ml of tetracycline simulated wastewater after adjusting the pH value into the reactor, then seal the reactor and keep the temperature at 85°C, and carry out the hydrolysis reaction for 6h (ie 360min);

[0085] Sampling time, sampling amount, detection method are identical with embodiment 1. The results of sampling time interval, tetracycline concentr...

Abstract

The invention provides a pretreatment method for removing antibiotics in ferment antibiotic pharmaceutical wastewater. The method removes antibiotics in the ferment antibiotic pharmaceutical wastewater mainly through adjustment of the pH value of the wastewater and high-temperature catalytic hydrolysis, and the treated pharmaceutical wastewater without antibiotics can enter a subsequent biochemical treatment process for treatment. The method provided by the invention can basically remove antibiotics in the pharmaceutical wastewater, reduce inhibition effect of high-concentration antibiotics on microbes, lower down difficulty in treatment of the wastewater by using the subsequent biochemical process and decrease generation of drug-resistant bacteria and drug-resistant genes in subsequent biochemical 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...
