Description
Technical field
This utility model belongs to wastewater treatment, environmental protection technical field, and in particular, more particularly to a kind of synthesis is more
Plant the biological reinforced processing meanss of penicillin wastewater of bioreactor advantage.
Background technology
Penicillin wastewater refers to the pharmacy corporation waste water that produces or other penicillium sp containing high concentration during production penicillin
The waste water of element, its constituent are complicated, and pollutant and solid suspension concentration are high, containing a large amount of hard-degraded substances, and often deposit
In excessive nitrogen and the penicillin and its by-product of residual, cause which that there is stronger Ecotoxicology and inhibition.At present
Have much for the method for penicillin wastewater process, can be divided mainly into two big class of materialization treatment process and biological treatment, wherein thing
Change facture and there is the shortcomings of operating cost is high, secondary pollution is serious, therefore, biological treatment is to process penicillin at present to give up
The primary means of water.But, penicillin wastewater impact load and variation water quality are big and have stronger toxic action to microorganism, make
Process is carried out to which with conventional biological treatment method and is difficult to efficient process, how to realize that the efficient process of penicillin wastewater are
One of environmental project problem of current urgent need to resolve.
The current feature according to penicillin wastewater, the handling process for mainly using include：Sequencing batch activated sludge reactor
(SBR), membrane bioreactor (MBR), MBBR (MBBR) etc..SBR collection homogenizing, just heavy, biodegradation and
Two functions such as heavy are integrated, with excess sludge it is few, take up an area less, operating cost is low, the method for operation is flexible, resistance to organic loading and poison
The characteristics of thing load impact, but which is higher to sludge settling property requirement, and after there is sludge bulking, effluent quality is decreased obviously, and
Which can not carry out continuous flow operation, and pond holds and utilization rate of equipment and installations is low.Activated sludge process and membrane separation technique collection are one by MBR
Body, can effectively retain sludge, retain generation cycle longer microorganism, keep high-biomass, therefore with stronger organic
Load and toxic load tolerance, and denitrification efficiency can be effectively improved, but its space availability ratio is not high, and membrane module price compared with
It is high.MBBR combines the advantage of bio-contact oxidation and biological fluidized bed, its can abundant effectively utilizes space reactor, formed
Floating biological film system, while system biological amount is improved, enhances contact of the pollution medium with microorganism, improves
The treatment efficiency and impact resistance of whole system for handling, it is possible to effectively overcome activated sludge process that lacking for sludge bulking easily occurs
Point, but its film forming period is relatively long, starts slow and unstable.
At present above-mentioned three kinds of reactors are widely used in sewage disposal, but due to its be individually present with
Upper shortcoming, so as to cause these three reactors to some special waters, the treatment effect of the such as antibiotic waste water such as penicillin is not good,
The water quality and quantity for being particularly due to the antibiotic waste waters such as penicillin is changed greatly, and is processed using above-mentioned three kinds of conventional reactor
Efficiency it is relatively low, and which cannot ensure the stability of effluent quality.
Jing is retrieved, with regard to the existing more disclosure of patent of Industrial Wastewater Treatment.As Chinese Patent Application No. is
201210468705.7 patent of invention discloses a kind of biological denitrification method of nitrogenous organic industrial sewage, the work of this application case
Industry wastewater treatment equipment includes regulating reservoir, MBBR and internal circulating membrane bioreactor, has nitrogenous first
Machine industrial wastewater is passed through in regulating reservoir with and pool inner water matter, then by floating stuffing input MBBR simultaneously
Biological Membrance cuiture is carried out, after biological Membrance cuiture terminates, will be carried out in the waste water input MBBR in regulating reservoir
Process；It is last that again the waste water Jing after MBBR process is input in internal circulating membrane bioreactor, interior circulation
Active sludge is thrown in membrane bioreactor, is run by the way of continuum micromeehanics, gap draining, continuous aeration, after process
Waste water discharge after the membrane filtration module of internal circulating membrane bioreactor, that is, complete nitrogenous organic industrial sewage biology take off
Nitrogen process.This application case can improve the biological denitrificaion treatment effect of nitrogenous organic industrial sewage to a certain extent, but for
Penicillin wastewater, as its water quality and quantity fluctuation is big, the method for this application case is not appropriate for.Additionally, the method for this application case begins
Eventually by membrane filtration module water outlet, membrane module cleaning frequency can be improved, shorten film service life, cause operating cost to increase.This
Outward, in this application case, MBBR and internal circulating membrane bioreactor are two independent reaction units, this
Result in floor space needed for which larger, cause capital cost to rise.
