Problems solved by technology

However, the content of residual antibiotics and related substances (residual potency) in the wastewater produced by fermentation antibiotics is high, which will cause serious environmental pollution and ecological problems without treatment or incomplete treatment
[0003] Fermentation antibiotic wastewater has high COD concentration, high ammonia nitrogen concentration, high suspended solids (SS) content, imbalanced carbon and nitrogen nutrition ratio, complex components, and residual antibiotics are inhibitory to microorganisms. It belongs to high-concentration refractory organic wastewater
Due to the complex water quality conditions of fermented antibiotic wastewater, especially the unstable biological treatment effect under the influence of some residual antibiotics and related substances, it is difficult for the effluent COD and ammonia nitrogen indicators of a large number of fermented antibiotic wastewater treatment facilities to meet the "fermented pharmaceutical industry" Water Pollutant Discharge Standard"
[0004] At present, in order to meet the discharge requirements of fermented antibiotic wastewater, the focus is on the advanced treatment after biochemical treatment, ignoring the optimization of pretreatment and biochemical treatment effects, resulting in complex treatment processes and high operating costs.

Abstract

The invention discloses a treatment system for ferment antibiotics wastewater. The treatment system comprises an adjusting tank, a cavitation air floatation machine, a coagulative precipitation tank,a hydrolysis acidification tank, a UASB reactor, a primary sedimentation tank, an A / O system, a secondary sedimentation tank, a Fenton oxidation reaction box, a reaction sedimentation tank and a sludge thickening tank which are successively connected. The invention further discloses a treatment method for the ferment antibiotics wastewater. The treatment method comprises the following steps: pretreatment: the adjusting tank, the cavitation air floatation machine and the coagulative precipitation tank; biochemical treatment: the hydrolysis acidification tank, the UASB reactor, the primary sedimentation tank, the A / O system and the secondary sedimentation tank; and advanced treatment: the Fenton oxidation reaction box and the reaction sedimentation tank. The combined technology is used for treating the ferment antibiotics wastewater, the biotoxicity of the ferment antibiotics wastewater is reduced, and the biodegradability of the wastewater is improved, so that the wastewater is discharged after reaching a standard, the treatment technology is simple, and the operating cost is low.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment system and process for fermented antibiotic wastewater. Background technique [0002] There are various types of antibiotics currently used clinically, and antibiotics have played an irreplaceable role in reducing disease suffering and prolonging human life. Among them, the largest production capacity and demand are fermented antibiotic raw materials. However, the content of residual antibiotics and related substances (residual potency) in the wastewater produced by fermentation antibiotics is high, which will cause serious environmental pollution and ecological problems without treatment or incomplete treatment. [0003] Fermentation antibiotic wastewater has high COD concentration, high ammonia nitrogen concentration, high suspended solids (SS) content, imbalanced carbon and nitrogen nutrition ratio, complex components, and residual antibiotics are inh...
