Embodiment 1

[0039] A pharmaceutical group company produces 180 tons of potassium clavulanate per year, and the total amount of sewage generated every day is about 3,000 cubic meters. The production of potassium clavulanate undergoes fermentation reaction, membrane filtration, solvent extraction, activated carbon decolorization, salt formation, and purification processes to produce high-concentration refractory organic wastewater containing a large number of pollutants: 1) Organic load: COD up to 15000mg / L, NH3- The N content exceeds 350mg / L; 2) The salt content reaches 5000mg / L; 3) The residual organic solvent ethyl acetate; 4) The color is heavy and the smell is heavy.

[0040] The production wastewater enters the comprehensive adjustment pool after being discharged from the workshop, and the solvent-containing wastewater passes through the recovery tower, and the COD is reduced to 4000mg / L.

[0041] In the two-phase anaerobic stage, the hydrolysis and acidification tank, in the hydrolys...

Embodiment 2

[0045] The processing method of this potassium clavulanate production waste water is carried out as follows:

[0046] a. Send potassium clavulanate industrial waste water to the recovery unit to recover ethyl acetate at 69.9°C;

[0047] b. Send the clavulanic acid potassium industrial waste water of a step through the recovery of ethyl acetate to the hydrolysis acidification tank, adjust the pH value to 9.0, and treat it with the hydrolysis acidification bacteria group in the hydrolysis acidification tank for 2 hours, then enter the anaerobic reactor, and Anaerobic flora including methanogens were treated for 48 hours;

[0048] c. Send the wastewater treated by anaerobic reaction in step b to the BDP treatment process, and control the dissolved oxygen of the wastewater to 0.1mg / L;

[0049] d. Send the wastewater treated by the BDP process in step c to the advanced oxidation process, first adjust the pH value of the wastewater to 3.5, and add hydrogen peroxide to the wastewate...

Embodiment 3

[0051] The processing method of this potassium clavulanate production waste water is carried out as follows:

[0052] a. Send potassium clavulanate industrial waste water to the recovery unit to recover ethyl acetate at 70.1°C;

[0053] b. Send the clavulanic acid potassium industrial waste water of step a through recovery of ethyl acetate to the hydrolysis acidification tank, adjust the pH value to 8.0, and then enter the anaerobic reactor for 4 hours in the hydrolysis acidification tank by including Anaerobic flora including methanogens were treated for 36 hours;

[0054] c. Send the wastewater treated by anaerobic reaction in step b to the BDP treatment process, and control the dissolved oxygen of the wastewater to 0.3mg / L;

[0055] d. Send the wastewater treated by the BDP process in step c to the advanced oxidation process, first adjust the pH value of the wastewater to 3.0, and add hydrogen peroxide to the wastewater according to the addition amount of 2.5ml / L and accor...

Abstract

The invention provides a treatment method for potassium clavulanate production wastewater. The method comprises the following steps that a, potassium clavulanate production wastewater is fed to a recycling device to recycle ethyl acetate under the temperature of 70+/-1 DEG C; b, the potassium clavulanate production wastewater obtained after ethyl acetate is recycled in the step a is fed to a hydrolysis acidification pool, the pH value is adjusted, hydrolytic acidification flora treatment is performed in the hydrolysis acidification pool for 2-4 h, and the production wastewater enters an anaerobic reactor to be subjected to anaerobic reaction treatment; c, the wastewater obtained after the BDP technological treatment is performed in the step c is fed to an advanced oxidation procedure, the pH value of the wastewater is adjusted to be 3.0-3.5, an oxidant is added into the wastewater according to the addition amount of 0.5-2.5 ml/L, ferrite salt is added into the wastewater according to the addition amount of 0.5-1.5 g/L, the aeration reaction is performed for 1-1.5, then, the pH value of the wastewater is adjusted to be 9-10, finally, coagulant aids are added, and Fe3+ precipitations are formed to reach the standard and perform emission.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a treatment method for biopharmaceutical industrial wastewater, in particular to a treatment method for the production wastewater of potassium clavulanate. Background technique [0002] Potassium clavulanate, chemical name: (Z)-(2S,5R)-3-(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo-3.2.0-heptane Potassium alkane-2-carboxylate has weak antibacterial activity, but it can be firmly combined with most β-lactamases to form irreversible conjugates, and has a strong and broad-spectrum inhibitory effect on β-lactamases. It has inhibitory effect on coccal enzymes, and it also has inhibitory effect on enzymes produced by a variety of Gram-negative bacteria. It is an effective β-lactamase inhibitor. [0003] The production of potassium clavulanate undergoes fermentation reaction, membrane filtration, solvent extraction, activated carbon decolorization, salt format...
