Description
Technical field
The present invention relates to the technical field of livestock breeding wastewater process, refer in particular to a kind of anaerobism bidirectional rotation membrane bioreactor for the treatment of livestock breeding wastewater and operation method thereof.
Background technology
The organism of livestock breeding wastewater, ammonia nitrogen, concentration of suspension are high, and direct discharge can cause serious threat to ecotope, thus needs to process discharge further to livestock breeding wastewater.Anaerobic Methods in Treating can be adopted with the recycling of the process and resource that realize waste water to the process of livestock breeding wastewater.
Anaerobic Methods in Treating is under anaerobic, by the acting in conjunction of obligate and amphimicrobe, is decomposed by organism, reclaims the energy and resource with the form of biogas, natural pond liquid and natural pond slag simultaneously.The development of this technology has over one hundred year history, has occurred a series of high efficiency anaerobic reactor in recent decades, as up-flow anaerobic sludge blanket, anaerobic filter, anaerobic fluidized bed etc.These reactors realize microorganism mainly through granular sludge and the biomembranous mode of formation and retain, and avoid microorganism to run off, improve processing power.When their high suspended matter waste water this kind of for livestock breeding wastewater, affect by suspended substance, easily occur that granular sludge is poor, blocking or the phenomenon such as short stream, processing power declines.Although traditional complete hybrid anaerobic digester is applicable to high suspended matter waste water, due to without microorganism retention functions, make processing efficiency low, take up an area large, capacity of resisting impact load is poor, fluctuation of service.Therefore, for livestock breeding wastewater, exploitation is efficient, stable, practical Novel anaerobic technique is very necessary.
In recent years, flourish along with domestic and international membrane technique, membrane sepn every field application gradually deeply, wherein, anaerobic membrane bioreactor, as the emerging dual-membrane process of one, receives publicity gradually.Anaerobic membrane bioreactor is the composite system that membrane technique combines with anaerobic treatment process.This process application is as follows in the advantage of livestock breeding wastewater:
(1) anaerobic membrane bioreactor operating load is high, takes up an area little.
Anaerobic membrane bioreactor does not rely on granular sludge and biofilm formation to retain microorganism; but rely on the separation of membrane module to realize the effectively catching of microorganism; ensure that microorganism concn higher in reactor, thus improve operating load, reduce reactor volume.
(2) anaerobic membrane bioreactor efficient stable more.
While anaerobic membrane bioreactor can mix between strengthening waste water and microorganism, still ensure comparatively high microorganism concentration and need not worry that microorganism is run off, thus improve processing efficiency and produce the ability of methane, strengthen capacity of resisting impact load, operating performance is stablized, and reduces follow-up management problem.In addition, due to the crown_interception of film, the suspended particulate in waste water and part pollutent can be retained in reactor for a long time, improve wastewater treatment and resource recovery further.
(3) anaerobic membrane bioreactor effluent quality is good.
Membrane module crown_interception can make system effluent quality be better than other anaerobic techniques.
(4) anaerobic membrane bioreactor technique is relatively simple, and can form integration apparatus, later stage running maintenance is easy.
Visible, this technique has significant advantage in livestock breeding wastewater process.But current fouling membrane is still a major reason of puzzlement anaerobic membrane bioreactor development.Fouling membrane can cause flux depression, affects the steady running of whole system.And during by the livestock breeding wastewater of anaerobic membrane bioreactor for the treatment of complicated component, membrane pollution problem may be more outstanding.Therefore, the practical application that the thorough solution that anaerobic membrane is polluted will advance anaerobic membrane bioreactor in livestock breeding wastewater process conscientiously.
At present, domestic and international investigator comprises the measure of control of fouling membrane in anaerobic membrane bioreactor and improves mixed liquor characteristics (as sludge concentration, dissolved organic matter, grain diameter etc.), adjustment operation condition (as membrane flux, transmembrane pressure, cross-flow rate and suction mode etc.), improves mould material and improves its resistance to crocking.
For comparatively traditional common external placed type anaerobic membrane bioreactor, high cross-flow rate is provided to be the mode generally adopted by pump circulation.And in recent years enjoying the immersion type anaerobic film bioreactor that the energy consumption of high praise is lower, investigators then usually consider to adopt the mode of biogas recirculation to carry out disturbance to alleviate fouling membrane on film surface.But, the operation relative complex of biogas recirculation, and the disturbance of biogas likely reduces sludge returning, thus cause negative impact.At present, for the problem of fouling membrane, a kind of novel anaerobic membrane bioreactor---anaerobism rotates membrane bioreactor and attracts attention.
It is exactly have employed the anaerobic membrane bioreactor rotating membrane module that anaerobism rotates membrane bioreactor.Wherein, the turbulent flow that rotation membrane module rotates formation by film self improves hydraulic shear with the formation of controlling diaphragm surface contamination layer.At present, the correlative study of anaerobism rotation membrane bioreactor is less.Rotating Plates membrane module was once used in anaerobic membrane bioreactor by the people such as Jiang, and have studied the start-up course of this reactor Anammox.Find in research, the membrane filtration characteristic that anaerobism rotates membrane bioreactor is better than traditional anaerobic membrane bioreactor.The people such as Bai Ling have developed a kind of immersion dual-axis rotation anaerobic membrane bioreactor and use it for treatment of simulated brewery wastewater.Result of study shows, relies on membrane module dual-axis rotation and the good hydraulics that formed can the development of effective controlling diaphragm pollution.But this immersion dual-axis rotation anaerobic membrane bioreactor is in actual motion, and membrane module easily breakage occurs, high to the requirement of manufacture technics, not easily amplifies popularization.And the above-mentioned rotation membrane module rotated in membrane bioreactor research about anaerobism all adopts single direction rotation mode.
Therefore, in order to improve preventing membrane pollution performance further, the present inventor makes further research this, and develop a kind of anaerobism bidirectional rotation membrane bioreactor for the treatment of livestock breeding wastewater and operation method thereof, this case produces thus.
