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 inh

Embodiment 1

[0028]A small-scale experiment was carried out at a biopharmaceutical company that produces penicillin and intermediate 6-APA using the PAOS combination process. The experimental design water flow rate was 4L / h, and the waste acid water, refining water and fermentation workshop water were pretreated and then mixed. , the COD, BOD, ammonia nitrogen, sulfate and chroma of the mixed wastewater are 12000-15000mg / L, 6000-7500mg / L, 500-600mg / L, 800-1200mg / L and 500-1000 times respectively. After oxygen treatment, COD, BOD, ammonia nitrogen, sulfate and chromaticity are 1500-2500mg / L, 300-600mg / L, 600-700mg / L, 10-50mg / L and 300-500 times respectively, and the anaerobic effluent enters After the I-BAF reaction tank, the effluent COD, BOD, ammonia nitrogen, sulfate radical and color are 300-500mg / L, 10-40mg / L, 5-10mg / L, 10-50mg / L and 150-300 times respectively, After the effluent of the IBAF reaction tank is improved by coagulation and sedimentation, the effluent COD, BOD, ammonia nitr...

Embodiment 2

[0030] A biopharmaceutical company mainly uses biological fermentation to produce penicillin and its intermediate 6-APA. During the production process, a large amount of waste water with high COD, high ammonia nitrogen, high sulfate radicals, and high salt content is produced. The B / C value in the waste water generated in some sections lower. The company currently has a set of wastewater treatment projects. The main process adopts the process flow of "wastewater adjustment + hydrolysis acidification + anaerobic + CASS". The anaerobic system cannot operate normally, resulting in an excessively high aerobic load in the latter part of the CASS. At present, the effluent of the system is difficult to discharge up to the standard. The enterprise is facing great environmental pressure. The adjustment and transformation of the existing sewage treatment system is imminent.

[0031] Combined with the nature of sewage discharge in the enterprise, and considering the full-load operation i...

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 ...
