Embodiment 1

[0053] Embodiment 1: a kind of advanced treatment method of biopharmaceutical sewage, described method passes through the following steps successively:

[0054] A medium-sized antibiotic biopharmaceutical enterprise in Shandong produces a total of 1200m of pharmaceutical wastewater 3 / day, the COD of aerobic effluent is 400-600mg / L, and the COD of the external drainage is between 250-330mg / L. During the implementation of the discharge standard system of COD<50mg / L, there are occasional times when the standard is not met. During the treatment of waste water by adopting the scheme involved in the present invention, the enterprise produces erythromycin thiocyanate to avoid the problem of not being able to achieve the standard. The specific process is as follows:

[0055] Wall breaking treatment and flocculant precipitation treatment: adjust the pH value of the wastewater to 7.0, add 0.03mg / L peptidoglycanase to the wastewater for wall breaking treatment, the treatment time is 2 ...

Embodiment 2

[0060] Embodiment 2: a kind of advanced treatment method of biopharmaceutical sewage, described method passes through the following steps successively:

[0061] A medium-sized antibiotic biopharmaceutical enterprise in Shandong produces a total of 1200m of pharmaceutical wastewater 3 / day, the COD of aerobic effluent is 300-500mg / L, and the COD of the external drainage is between 200-300mg / L. During the implementation of the discharge standard system of COD<50mg / L, it failed to meet the standard many times. During the treatment of waste water by adopting the scheme involved in the present invention, the enterprise carries out the production of tetracycline, so as to avoid the problem that the standard cannot be achieved. The specific process is as follows:

[0062] Wall breaking treatment and flocculant precipitation treatment: adjust the pH value of the wastewater to 7.0, add 0.01mg / L peptidoglycanase to the wastewater for wall breaking treatment, the treatment time is 2 hou...

Embodiment 3

[0067] Embodiment 3: a kind of advanced treatment method of biopharmaceutical sewage, described method passes through the following steps successively:

[0068] A medium-sized antibiotic biopharmaceutical enterprise in Shandong produces a total of 1200m of pharmaceutical wastewater 3 / day, the COD of aerobic effluent is 400-600mg / L, and the COD of the external drainage is between 250-330mg / L. During the implementation of the discharge standard system of COD<50mg / L, there are occasional times when the standard is not met. During the treatment of waste water by adopting the scheme involved in the present invention, the enterprise produces erythromycin thiocyanate to avoid the problem of not being able to achieve the standard. The specific process is as follows:

[0069] Wall breaking treatment and flocculant precipitation treatment: adjust the pH value of the wastewater to 7.0, add 0.05mg / L peptidoglycanase to the wastewater for wall breaking treatment, the treatment time is 2 ...

Abstract

The invention discloses an advanced treatment method for antibiotic drug sewage, and belongs to the field of wastewater treatment. The treatment method comprises the following units of a pretreatment modification unit, a first catalytic reaction unit, a biological catalytic reaction unit, a second catalytic reaction unit and a physical precipitation unit. The method is used for treating production wastewater of antibiotics such as erythromycin thiocyanate, tetracycline, lincomycin, penicillin and the like, wherein the operation is efficient, the effluent quality is safe and stable, and virtuous cycle and green production of water resources in enterprises can be realized.

Description

technical field [0001] The invention relates to an advanced treatment method of biological drug sewage, in particular to a wastewater treatment method for the production of erythromycin thiocyanate, penicillin and tetracycline produced in a fermentation process, and belongs to the field of wastewater treatment. Background technique [0002] The sewage of biomedicine is mainly reflected in the mass production of raw materials, especially the antibiotics that are currently used in large quantities, such as penicillin, erythromycin and other antibiotics and their intermediates. Recycling and other processes, and erythromycin thiocyanate is a macrolide antibiotic, which is mostly used in the synthesis of antibiotics such as azithromycin, erythromycin, roxithromycin, and clarithromycin. In the process of extraction, salt formation and purification of erythromycin thiocyanate, high-concentration refractory organic wastewater containing a large amount of pollutants is produced. T...
