Processing unit, the patent needs to carry out using alkalization, acidifying, activated carbon and ozone treatment cephalosporin synthesis pharmaceutical waste water, the method
The treatment of later stage acid mist simultaneously can produce a large amount of spent acid salkali waste, easily bring secondary pollution.Patent CN104628199A discloses a kind of head
The processing method of spore Qusong waste water, the patent is using extraction, acidifying, the centrifugation of being added methylene chloride in alkalization, stratification, organic phase
To ceftriaxone wastewater treatment, the complex technical process need to be used organic molten the steps such as separation, charcoal absorption and ozone oxidation
Agent, easily causes secondary pollution to environment.Patent CN101434437 discloses a kind of by aerobic contact oxidation, anaerobic hydrolysis acidifying
Combine to process cephalosporin synthesis pharmaceutical waste water with membrane bioreactor, waste water in biological contact oxidation pond removal waste water first by that can give birth to
The preferable part organic matter of the property changed, then carries out biological hydrolysis acidifying in anoxic pond, and membrane bioreactor is then flowed into again
In carry out final Aerobic biological process, the waste water after treatment is by qualified discharge after the ultrafiltration membrane treatment in membrane bioreactor
To outer discharge pipe or it is back to use in production technology, the technological process is more long, and floor space is larger.Therefore, how at economical and effective
Reason antibiotic waste water is the problem of current scientific research personnel's urgent need to resolve.
The content of the invention
It is contemplated that overcoming problem present in existing antibiotic waste water treatment, there is provided a kind of simple, efficient, environmental protection
Bio-electrochemical process processes antibiotic waste water, and bioelectrochemistry is coupled into sequencing batch biofilm reactor
In (Sequencing Biofilm Batch Reactor, SBBR) reactor so that reactor synchronously carry out electrolytic oxidation and
Biological treatment, it is not necessary to which extra sedimentation basin, process is simple to operation, during will not relate to organic solvent, acid or alkali etc., also
The burden of secondary pollution will not be brought, environmentally friendly, reactor water outlet meets pharmacy waste water emission request.
To achieve the above object, the present invention provides following technical scheme：
A kind of bio-electrochemical reactor for processing antibiotic waste water, including bed body, dc source, raw water storage tank, mixing
Groove, preheating apparatus, injector, electrolysis promote agent storage device, enzymatic activity regulation agent storage device, aerator (9), gas
Flowmeter, aeration tube, second pond, anode electrode, cathode electrode, exhaust outlet, filler；The raw water storage tank is connected by pipeline and pump
Be connected to mixing channel, the electrolysis promotes agent storage device to be connected to mixing channel by the injector, mixing channel by pipeline with
Pump and the water inlet for being connected to bed body, are provided with preheating apparatus, the enzymatic activity conditioning agent storage between mixing channel and bed body
Device is connected to bed body by switch valve, and the delivery port of bed body is connected to the second pond, described anode by pipeline and pump
Electrode and cathode electrode are respectively placed in bed body both sides and are connected with dc source and controller by wire, described filler filling
In bed body, the aeration tube is distributed in bed body bottom, the external gas flowmeter of aeration tube and aerator.
Further, in such scheme, the bed body is made up of concrete or ceramic insulating material.
Further, in such scheme, the material that the anode electrode is used is platinum (Pt) or iridium (Ir), cathode electrode
The material of use is also platinum (Pt) or iridium (Ir).
Further, in such scheme, described filler is compounded mix, by weight component meter, is by following component group
Into：Polypropylene 40-100 parts, methacrylic acid-beta-hydroxy ethyl ester 20-50 parts, 5-20 parts of modified activated carbon particle, 3-20 parts of boiling
Stone, 1-8 part anthracite, 2-20 parts of fiberfill, 5-30 parts of floating stuffing.The modified activated carbon particle is through at Nitric Acid Modified
The activated carbon granule of reason；The fiberfill be by carbon nano-fiber with, glass fibre, polypropylene fibre be according to 3:1:2 weight
Measure the mixing of ratio.The compounded mix porosity is big, and specific surface area is big, and microorganism tack is good, for the nitrifier of autotrophy provides good
Good living environment, the advantage of high treating effect easy with clean and maintenance and operation.
Further, in such scheme, the packing ratio of described filler is 35-50%.
Further, in such scheme, it is sodium chloride that the electrolysis promotes the electrolysis accelerator in agent storage device.
Further, in such scheme, the enzymatic activity conditioning agent choosing in the enzymatic activity regulation agent storage device
From MgSO4、FeSO4、ZnSO4、CaCl2、MnSO4In one kind, two or more.
The present invention also provides a kind of method of work of the bio-electrochemical reactor for processing antibiotic waste water, including following step
