Description
Technical field
The invention belongs to membrane bioreactor (MBR) technical field.Relate to the negative charge that utilizes faint electric field and negative pole membrane contaminant generation repulsive force is slowed down the light current that pollutes, utilizes the metabolism of electric field-enhanced microorganism and utilize microbiological fuel cell to produce with controlling diaphragm.The principle that is specifically related to utilize the electronegative mostly characteristics of membrane contaminant among the MBR and the same sex to repel each other, place negative electrode or directly utilize conducting film to make negative electrode in membrane module, apply weak electric microfield, negative pole produces repulsive interaction to pollutent, delay the formation of cake layer, controlling diaphragm pollutes.Because institute's voltage that applies is lower, can utilize microbiological fuel cell that reactor is powered, have characteristics energy-conservation and fortified water treatment effect and performance.Simultaneously, faint electric field influence microbial metabolic activity and composition provide the novel method and the new direction that improve the water treatment effect.
Background technology
MBR is widely used in separation, water treatment, bio-pharmaceuticals etc.When being used for water treatment, long because of its sludge retention time, floor space is little, easy and simple to handle and level of automation is high receives much concern.Application in water treatment and market enlarge just year by year.The bottleneck factor of large-scale application changes film into by the film cost and pollutes.For keeping certain flux level and keeping normal operation, must spend a large amount of energy and medicament to eliminate the negative impact that film pollutes.This means that also alleviating film pollutes and can prolong normal operating period, reduces to shut down and carries out cleaning frequency membrane, can significantly improve the efficient of water treatment field, realizes the energy-saving and emission-reduction on higher level.
The MBR film pollution origin cause of formation and the Control Study of slowing down are numerous, and because of fundamentally not solving membrane pollution problem, this field is still the research focus.Pollute the origin cause of formation about the MBR film, people are consistent to think that extracellular polymeric (EPS), microorganism and some inorganic salt are main membrane contaminant.EPS mainly comprises protein, polysaccharide and nucleic acid.EPS and microorganism are electronegative mostly.These pollutents form cake layer or cause the obstruction in hole in films at face, cause the film effluent flux to descend.With the exception of this, film pollutes also relevant with the inorganic scale precipitation.
The method of eliminating film pollution recovery flux mainly contains physics and cleans and matting.Physics cleans and comprises that mainly face cleans and back flushing, and water is produced in this method consumption, and is difficult to clean comparatively completely; Matting generally after physics cleans, has medicament cleanings such as pickling, alkali cleaning and clorox etc., and the original position dosing also has employing, and this method is difficult to carry out, and might cause secondary pollution;
The method of decelerating membrane pollution has physical methods such as aeration, concussion, rotation, in the hope of reducing the absorption deposition of pollutent.Also have adopt operational condition optimization, medicament add, apply electric field, ultrasonic, carry out method such as membrane module optimization.The optimization of operational condition is very effective to the control that film pollutes, especially aeration intensity and hydraulic detention time are bigger to the speed influence that film pollutes, regrettably MBR kind and scale are different, still do not have the optimization that unified rule and model come the guiding operation condition up to now; Medicament adds and mainly is meant adding of various flocculation agents, increases the flocculation particle, and this method can increase processing cost and mud discharging undoubtedly; Apply the electric field controls film pollute then possess in-situ control, level of automation height, advantage that universality is good, therefore become the research focus gradually, but the suspicion that increases energy consumption also arranged.Existing report generally all adopts higher strength of electric field, and this is in the today of advocating energy-saving and emission-reduction, makes it feasibility and economy descends greatly.
Studies show that under extra electric field (20V/cm) effect hollow fiber film assembly surface cake layer thickness reduces (Jun-Ping Chen et.al.Study of the influence of the electric field on membraneflux of a new type of membrane bioreactor.Chemical Engineering Journal.2007.).Electric field is applied among the separated type MBR also can keeps membrane flux preferably, and fenestra helps the recovery of membrane flux for a short time, intermittently power supply same effectively (Kazuki Akamatsu et.al.Development of a novelfouling suppression system in membrane bioreactors using an intermittent electricfield.water research.2010.).Electrode is directly placed MBR, hollow-fibre membrane is discovered that the mud Zeta potential increases, Sludge Surface colloid form improves, and filtration capacity improves (Khalid Bani-Melhem et.al.Development of a Novel Submerged Membrane Electro-Bioreactor (SMEBR): Performance for Fouling Reduction.Environ.Sci.Technol.2010.).The author thinks that effect of electric field mainly is electricity flocculation and electric sedimentation, and colloidal solid becomes big under electric field action, is not easy to block fenestra, pollutes thereby reduce film.The voltage that above-mentioned institute applies is all bigger, and this is unfavorable for microbial growth and energy efficient.Because have little effect under the weak electric field, also nobody studies.Study also less about electric field to the influence of microorganism, the influence of water treatment capacity.
The microorganism that adapts to electric field is after domestication, and metabolic capacity is improved under effect of electric field, so the present invention's metabolism of also directly having stimulated microorganism when controlling diaphragm pollutes, has strengthened it and has handled the ability of some pollutents.
The present invention has changed the position of negative electrode, be placed on after the film or directly make the film conduction as negative electrode, make its repulsion that mud is produced directly pass film and realize, can pollute control to film like this and play direct effect, also just must reduce the voltage that is applied, voltage of the present invention only also produces appreciable results for 0.2V less than 0.5V.And this voltage can utilize microbiological fuel cell that reactor is powered fully, and this has eliminated the doubt that energy consumption improves undoubtedly fully, and microbiological fuel cell also can treating part sewage simultaneously, and this must form the situation of achieving many things at one stroke.
Summary of the invention
The objective of the invention is: utilize faint electric field that the MBR film is polluted and carry out original position and control efficiently.And taking from copper wire in the lead, then broken the constraint of electrode selection as anode with stainless steel as negative electrode, for the application of this invention provides cost savings; The application of electric microfield has then significantly reduced energy consumption, has eliminated the high doubt of energy consumption.
Technical scheme of the present invention is: this membrane bioreactor comprises the water inlet that all has of general membrane bioreactor and water level control system, outlet system, aerating system, electric field supply system.And key component be improved weak electric field applying method and device and with the organic coupling of membrane module.Electric field can be supplied with D.C. regulated power supply or microbiological fuel cell.Apply weak electric field voltage less than 0.5V, field intensity is less than 0.2V/cm.
Too fast for avoiding excessive suction to cause film to pollute, the present invention adopts intermittently water outlet, keeps electric field start-stop ratio that applies and the start-stop that aspirates water outlet than consistent simultaneously, and the repulsion of negative electrode works simultaneously to avoid the too fast formation of cake layer when suction; Electric field disappears when stopping to aspirate, and aeration can make the material of the positively charged of face absorption be washed away, thereby avoids forming electrostatic double layer.
The present invention is by directly apply electric field on after-applied electric field of face or use conducting film, so that directly repel pollutent, with control and decelerating membrane pollution.Because electric field acts directly on the film or near the face, employed voltage and strength of electric field are less, the result shows that the film pollution has obtained control preferably under weak electric field, and it is all comparatively slow to show as flux lowering speed and transmembrane pressure lift velocity.The higher flux level and the long cycle of operation have been kept.
Effect of the present invention and benefit are easy and simple to handle, can directly reequip pre-existing reactors, applying of electric microfield is then low to the consumption of the energy, use the microbiological fuel cell of sewage disposal or sludge treatment then to avoid adding energy consumption fully, become the facility of giving up to green energy resource, the raising water treatment efficiency more being provided.
