Problems solved by technology

Compared with the existing Sequencing Batch Activated Sludge Process (SBR), MBR can greatly reduce the floor area and improve the quality of the effluent, but the membrane surface is susceptible to being attacked by proteins and hyphae in the wastewater during operation. Fouling and clogging, resulting in frequent replacement of membrane components and high operating costs

Abstract

The invention discloses an antibiotic pharmaceutical wastewater processing method and an antibiotic pharmaceutical wastewater processing device, and belongs to a wastewater processing technology. According to the invention, a porous filtering membrane is specifically arranged between an anion-exchange membrane and a cation-exchange membrane of an electrodialyzer membrane reactor, such that electrodialysis is intrinsically coupled with a membrane filtering process. Macromolecular substances such as mycelia, proteins, and colloidal are retained with a sieving effect of the porous filtering membrane, such that ion-exchange membrane surface pollution is reduced. Also, under an effect of a direct current electric field, with a selective permeability of the ion-exchange membranes upon charged ions, separation and concentration of anions and cations, and charged antibiotic ions are realized. With an adopted external direct current electric field, a specific solute can be effectively prevented from forming membrane pollution on the surface of the porous filtering membrane, such that the processing process can be safely and stably operated. With the method and the device, antibiotic wastewater processing system investment and operation cost can be greatly reduced; and salt ions and residual antibiotics can be highly efficiently recovered from pharmaceutical wastewater. The method and the device have important application values in antibiotic production and wastewater processing.

Description

technical field [0001] The invention relates to a treatment method and device for antibiotic pharmaceutical wastewater, in particular to a treatment method for antibiotic pharmaceutical wastewater organically combining electrodialysis and membrane filtration, which belongs to wastewater treatment technology. Background technique [0002] Antibiotics produce a large amount of wastewater in the production process. Its composition is extremely complex, the discharge volume is large, the color is high, the salt content is high, the biotoxicity is high, and it is difficult to biodegrade. After being discharged into the river, it will seriously consume oxygen and destroy the self-purification of natural water bodies. Ability to cause water quality deterioration, water stench, and public nuisance. Therefore, the pharmaceutical industry has been listed as one of the 12 industries that need to be treated in the national environmental protection plan, and the pharmaceutical wastewater...
