Process for treating antibiotic waste water and usage thereof

Abstract

The invention provides a processing technique of waste water containing antibiotic and the purpose thereof, wherein, the technique adopts the following steps: pretreatment, two-phase anaerobic, improving SBR, immobilized microorganism-aeration biological filter, and improving the coagulating sedimentation combination technique. The detailed technique is introduced in the specification. The invention has the advantages that the industrial waste water is pretreated and the two-phase anaerobic technique is adopted, the great mass of sulfate radical is eliminated, the treatment effect for producing firedamp anaerobic phase and the stability of operation are improved, the energy is recycled and the operating cost is lowered; through the immobilized microorganism-aeration biological filter, the biological treatment effect is improved, and the operating cost for back end processing is lowered; the deep processing can ensure that the waste water is discharged by reaching the standard, and can meet the requirement to the upgrade and reorganization of sewage treatment plants when the environment protection standard is improved in the future. The invention has the purpose that the processing technique not only is applicable to the treatment for the waster water containing antibiotic and the upgrade and reorganization of the prior engineering of sewage disposal, but also is applicable to the engineering of sewage disposal and other sewage disposals with high salt content, high sulfate radical content, high ammonia and nitrogen content, high COD content and higher concentration organic matter which is hard to be degraded.

Description

technical field [0001] The present invention relates to the field of industrial wastewater treatment, more specifically, relates to a process for antibiotic wastewater treatment, specific industries include antibiotic pharmaceuticals and similar high salt, high sulfate, high ammonia nitrogen, high COD and contain relatively high concentrations Wastewater treatment and engineering transformation of refractory organic matter. Background technique [0002] Antibiotic wastewater is one of the most difficult types of industrial wastewater to treat. It is characterized by: 1) high COD (10-80g / L) and high SS (suspended solids) (0.5-25g / L) from fermentation residual nutrients; 2) presence of bioinhibitory substances, such as residual antibiotics and their intermediates Metabolites, high-concentration sulfates, surfactants (demulsifiers, defoamers, etc.) and high-concentration acids, alkalis, organic solvents, etc. remaining in extraction and separation; 3) Large fluctuations in pH ...

AI Technical Summary

Problems solved by technology

The biological aerated filter integrates adsorption, oxidation and filtration, and has good treatment effect, less sludge, low power consumption, and good effluent quality. It is an advanced technology for water treatment at present. Ceramics and other materials are used as filter materials, which have a large specificity, so the biggest problem encountered in operation is that it is difficult to backwash

Excessive ammonia nitrogen will inhibit microorganisms in traditional biological treatment, so it is difficult for ordinary biological treatment processes to achieve ideal treatment effects for high-concentration organic sewage and high ammonia nitrogen sewage

At the same time, the traditional biological treatment process generally has disadvantages such as large investment, high operating cost, large floor area, complex operation and management, and low processing efficiency.
