Description
Technical field
The invention belongs to technical field of waste water processing, be specifically related to a kind of waste water produced from penicillin productionAdminister technique.
Background technology
Penicillin belongs to the antibiotic of beta-lactam. Penicillin (Penicillin, or soundTranslate penicillin) refer in molecule and contain penam, can destroy the cell membrane of bacterium and on bacteriumPlay a class antibiotic of bactericidal action the breeding period of cell. Its chemical formula is C16H18N2O4S. Blue or greenThe workshop technique waste water producing in mycin production process has following features: 1) pollutant levelsHeight, pollutant component complexity, the residual media matter, product, impurity, the biology that contain fermentationMetabolic intermediate etc., COD is generally at 11000mg/L-23000mg/L; 2) difficult for biological degradation thingMatter content is high, and bio-toxicity Material Source has three approach a, because antibiotic yield is lower,Be only 0.1%～3% (mass fraction), and only 60%～70% (mass fraction) of separation and Extraction rate,Therefore the higher B of residual antibiotic content in waste water, be microbial metabolism product. C, send outThe organic or inorganic salt adding in ferment or leaching process, 3) approximately 90 DEG C of waste discharge temperature;4) feature such as large, the intermittent discharge of the water yield, the discharge of this waste water become limit this product andThe bottleneck of Sustainable Development of Enterprises. About such method of wastewater treatment, domestic patentCN103172173A " a kind of penicillin wastewater preprocess method ", specifically utilizes hydrolysis acidMetallization processes is carried out pretreatment to high concentration penicillin wastewater, waste water SS reduction after treatment 85%～90%, COD reduces by 30%～35%, and Penicillin Content reduces by 75%～80%. Patent CN1110257A" a kind of method of processing waste water produced from penicillin production ", specifically adopts aerobic batch (-type) active dirtyMud method (SBR) is processed penicillin wastewater, patent CN1041927A " penicillin wastewater processingMethod ", specifically adopt flocculation-precipitation-anaerobic-aerobic group technology to process penicillin wastewater.Although above processing method can reduce certain COD, all can not fundamentally solve penicillin uselessThe high remnants of the water difficult biochemical problem causing of tiring, therefore, finds a kind of economic technology feasible,Treatment effect is stable, effectively improves the pretreating process of penicillin wastewater biodegradability for promotionIndustry development and environmental protection tool are of great significance. The present invention administers technique and belongs to both at home and abroadPioneering, domestic and foreign literature and patent retrieval are all without report.
Summary of the invention
The object of the present invention is to provide that a kind for the treatment of effect is good, production cost is low, be convenient to industryProduce, simply easy to operate and do not produce low-temperature catalyzed wet oxidation process in the catalysis of secondary pollutionProcess the method for waste water produced from penicillin production, thoroughly to solve the danger of waste water produced from penicillin production to environmentEvil property.
For achieving the above object, technical solution of the present invention is as follows:
A kind of waste water produced from penicillin production is administered technique, is mainly to use low-temperature catalyzed wet type in catalysisOxidation technology is processed waste water produced from penicillin production. Waste water COD clearance > after this PROCESS FOR TREATMENT60%, chroma removal rate is large 99%, and B/C rises to 0.8 by 0.35. Technical scheme of the present inventionCarry out according to following concrete operation step:
Waste water produced from penicillin production is joined in autoclave, add catalyst, stir, withAir is oxidant, under heating condition, removes the remaining antibiosis in waste water by oxidation reactionThe bio-toxicity materials such as element, isomers. 130～170 DEG C of reaction temperatures, reaction pressure is 0.5～3MPa, wherein partial pressure of oxygen is 0～1.0MPa, the reaction time is 1～2 hour.
As embodiment preferably, described catalyst be copper sulphate, ferrous sulfate, manganese chloride,One or more mixtures in zinc sulfate;
The dosage of described catalyst is mass ratio 0.1%～1%.
The pH value of reaction is 4～7;
Compared with prior art, tool of the present invention has the following advantages:
1. for the feature dirt such as former medicine active component, poisonous and harmful intermediate containing in waste waterDye thing and adopt this preconditioning technique, thoroughly solve environmental pollution and ecology that antibiotic residue causesDestruction problem.
When 2.COD reduces by 50%, chroma removal rate reaches more than 97%. After this technical finesse,Waste water B/C value is brought up to more than 0.85, can guarantee that waste water is through biochemical treatment qualified discharge.
3. the method reaction condition gentleness, taking air as oxidant, temperature and pressure are wanted equipmentAsk more similar technology low, catalyst amounts is few and with low cost, has good marketingBe worth and industrial applications prospect.
