Description
Technical field
What the present invention relates to is a kind of treatment process of wastewater from cephalosporin synthesis pharmaceutical production, belongs to water-treatment technology field.
Background technology
Wastewater from cephalosporin synthesis pharmaceutical production belongs to the high density waste water difficult for biological degradation because composition complexity, organic concentration height, biodegradability are poor, does not still have the rational treatment technology of mature and reliable, investment and running cost at present both at home and abroad.It is external that what generally adopt is to concentrate burning, chemical oxidation and this waste water of wet oxidation technical finesse, concentrate burn and wet oxidation technical finesse effect fine, do not produce secondary pollution substantially, still invest hugely, domestic enterprise is unable substantially to be born.Therefore, still there is not engineering to use at home; Though chemical oxidization method is invested little, running cost is very high, and more than the hundreds of easily units of the processing costs of waste water per ton, and treatment effect is unsatisfactory, generally all as pre-treatment or post-processing technology.Domestic enterprise generally adopts chemical oxidation, flocculation sediment, anaerobic biological treatment and conventional aerobe to handle the bonded Technology, adopt this art breading wastewater from cephalosporin synthesis pharmaceutical production, have technical process length, long, the very high defective of running cost of hydraulic detention time, the waste water of this art breading of process can not long-term stability reach wastewater discharge standard mostly.Therefore, pharmacy waste water is known as the most unmanageable waste water in the wastewater treatment industry, also is the great restraining factors of the domestic and international pharmacy corporation development of influence.
In recent years, membrane bioreactor is obtaining attention as the combination of high performance membrane isolation technique and traditional activated sludge process aspect the pharmaceutical industry wastewater treatment.For hardly degraded organic substance, because the microorganism in the membrane bioreactor can not run off, sludge concentration is high especially, has guaranteed that the kind of microorganism in Russia's reactor is abundant, helps the bacterium of special treatment effect of enrichment those have to(for) hardly degraded organic substance.Combination process based on the Membrane Bioreactor for Wastewater Treatment pharmacy waste water is also further developed, the face and the method that combine as coagulating sedimentation+sand filtration+membrane bioreactor+activated carbon+ozone process, acidication+membrane bioreactor, the separate type membrane bioreactor that upflowing catalytic oxidation post and catalytic oxidation groove are formed in the film system etc.Though it is not above-mentioned method of wastewater treatment has certain treatment effect to general pharmacy waste water, good for the treatment effect of wastewater from cephalosporin synthesis pharmaceutical production.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of organism major part in the waste water is removed, and effluent quality is better than state three grade emissioning standard, and can directly discharge, and also can be used for the treatment process of the wastewater from cephalosporin synthesis pharmaceutical production of production technique.
The objective of the invention is to finish by following technical solution, it is mainly by aerobic contact oxidation, and anaerobic hydrolysis acidifying and Membrane Bioreactor for Wastewater Treatment three parts constitute; The waste water that produces in the described cephalosporin synthesis pharmaceutical production method is removed that part of organism of good biodegradability in the waste water earlier by biological contact oxidation pond, in anoxic pond, carry out the biological hydrolysis acidifying then, improve the biodegradability of waste water, and then carry out final aerobe in the inflow membrane bioreactor and handle, waste water after the processing is through the ultra-filtration membrane in the membrane bioreactor, pump out by going out water pump, qualified discharge is to outer discharge pipe or be back to use in the production technique; The hydraulic detention time of membrane bioreactor is 20 hours in the described treatment process, and volumetric loading is 4.5kgCOD/m
3.d, sludge concentration is 6-10g/l, and membrane flux is 10L/m
2.h, resistance of membrane filtration is less than 30kPa; Factory effluent COD 4000-7000mg/l, BOD
550-300mg/l, water outlet COD≤100mg/l, BOD

Described membrane bioreactor is a core processing unit of the present invention, it is made of aeration zone and membrane filtration district, the aeration zone adopts the disc type micro porous aeration head to carry out aeration, ultra-filtration membrane is placed on the membrane filtration district, through the waste water after aerobic contact oxidation, the anaerobic hydrolysis acidification, organism wherein is substantially by biological degradation, and waste water is extracted out through in the ultra-filtration membrane, and the microorganism in the reactor is blocked in the reactor.
The present invention is directed to the characteristics of production of raw medicine concentration of organic wastewater height, biodegradability difference, adopt aerobic contact oxidation, anaerobic hydrolysis acidifying and membrane Bio-reactor Technology that this kind waste water is carried out a biological disposal upon, because membrane bioreactor has adopted ultra-filtration membrane, it has following advantage: because the microorganism of membrane bioreactor can not run off, sludge concentration is high especially, and does not need to establish second pond, therefore, it is very high that it handles load, and floor space is little; Effluent quality is good, does not particularly contain suspended substance, might be back to use in the production; Microorganism can not run off in the membrane bioreactor, guaranteed that also the kind of microorganism is extremely abundant in the reactor, some be difficult for growth, have the bacterium of special treatment effect also can in reactor, reach very high amount for hardly degraded organic substance, therefore, membrane bioreactor has special processing power for organic wastewater with difficult degradation thereby; Sludge age is long, and sludge yield is little, has reduced the trouble of sludge treatment.
The present invention is with respect to prior art, and it is simple to have technology, good waste water treatment effect, and floor space is little, and processing cost is low, is particularly useful for the characteristics such as waste water that produce in the cephalosporin synthesis pharmaceutical production.
