Comprehensive treatment system for fermented antibiotic pharmaceutical wastewater

Abstract

The invention relates to a pharmaceutical wastewater treatment system and in particular relates to a comprehensive treatment system for fermented antibiotic pharmaceutical wastewater. The system can be used for pre-treatment, biochemical treatment and advanced treatment of fermented antibiotic pharmaceutical wastewater, so that the stability of the anaerobic system is improved, the anaerobic investment is reduced, the anaerobic efficiency is improved, and moreover, in the advanced treatment stage, hardly degraded pollutants are removed through Fenton catalytic oxidation reaction, so that the wastewater is discharged by reaching the standard.

Description

technical field [0001] The invention relates to a pharmaceutical wastewater treatment system, in particular to a comprehensive treatment system for fermented antibiotic pharmaceutical wastewater. Background technique [0002] Fermentation antibiotic pharmaceutical wastewater contains pollutants such as dregs, sundries, solvents, refining residues, and a large number of organic pollutants and salts that are difficult to biodegrade. The main pollutants include: heterocyclic organic matter, esters, benzene rings Organic matter, protein, drug residues, organic solvents, etc., and the amount of wastewater is large, if it is directly discharged, it will cause serious pollution. At present, most fermentation antibiotic pharmaceutical companies have many problems in the treatment of factory production wastewater: such as complex treatment process, Low pollutant removal efficiency, unstable anaerobic process, poor treatment effect, high investment, difficult to remove insoluble COD, ...

[0002] Fermentation antibiotic pharmaceutical wastewater contains pollutants such as dregs, sundries, solvents, refining residues, and a large number of organic pollutants and salts that are difficult to biodegrade. The main pollutants include: heterocyclic organic matter, esters, benzene rings Organic matter, protein, drug residues, organic solvents, etc., and the amount of wastewater is large, if it is directly discharged, it will cause serious pollution. At present, most fermentation antibiotic pharmaceutical companies have many problems in the treatment of factory production wastewater: such as complex treatment process, Low pollutant removal efficiency, unstable anaerobic process, poor treatment effect, high investment, difficult to remove insoluble COD, lack of effective advanced treatment methods, etc. If only biochemical treatment methods are used, pollutants that are difficult to biochemically degrade will remain in the In the wastewater, it makes it difficult for the effluent to meet the requirements of the "Discharge Standard of Pollutants for Fermentation Pharmaceutical Industry" (GB21903-2008), resulting in the discharge of wastewater that cannot meet the standard

However, most of the advanced treatment technologies for fermented antibiotic wastewater are still at the laboratory level, which is difficult to achieve in practical applications.
