Description
Technical field
The present invention relates to a kind of membrane bioreactor.
Background technology
At present, other many countries of the China and the world generally adopt aerobic means such as the various sewage of Wastewater Treated by Activated Sludge Process, though aerobic process can reach treatment effect preferably, but still have a series of problems: 1, energy consumption height: aerobic process needs sewage is carried out oxygenation, needs to consume a large amount of electric energy.It is estimated, a Sewage Plant that adopts traditional activated sludge process, 75% of overall running cost expends on electric energy, and the burden on still energy-conservation economically is all heavier; 2, sludge yield height: the productive rate of aerobic microbiological is generally up to 0.2-0.6kgVSS/kgCOD, therefore need dewater to mud, subsequent disposal such as security landfill or burning, increased the cost of sewage disposal; 3, add organic carbon source: need additional carbon for the insufficient waste water of some carbon sources, increased operational and administrative expenses; 4, management is inconvenient: the infrastructure investment of aerobic process is bigger, and the operational management inconvenience, is not suitable for developing the cities and towns and the rural area that fall behind relatively and uses.
Anaerobic ammonia oxidation process can be saved 60% running cost than traditional technology, has therefore begun the industrial experimentation research that anaerobic ammonia oxidation process is handled nitrogenous effluent abroad.The enrichment culture anaerobic ammonia oxidizing bacteria is the key of successful Application anaerobic ammonia oxidation process.At present, the reactor that is used for the enrichment culture of anaerobic ammonia oxidizing bacteria mainly contains sequencing batch activated sludge treatment system SBR, up flow anaerobic sludge blanket reactor UASB, membrane bioreactor MBR etc.The main drawback that the reactor of these several enrichment culture exists is as follows:
1, SBR, UASB may cause sludge loss.These two kinds of reactors utilize the settling property of mud self to carry out mud-water separation, therefore may not produce sludge loss when the sedimentation function of Anammox mud is good.Because the growth cycle of anaerobic ammonia oxidizing bacteria is long, sludge loss can cause enrichment culture long, even the enrichment failure.
2, built-in MBR changes the membrane module problem.Though built-in MBR has solved the sludge loss problem, but frequent replacing membrane module may destroy the environment of the strictly anaerobic of anaerobic ammonia oxidizing bacteria needs.In addition, should not form microbial film in the MBR reactor, and existing studies confirm that, microbial film is to keep the slowly good carrier of growth bacterial classification such as anaerobic ammonia oxidizing bacteria.
In addition, because anaerobic ammonia oxidizing bacteria is relatively strict to environment requirement, and is poor to the resistibility of poor environment, also has a certain distance from the application of actual engineering, therefore it is strong to demand developing a kind of adaptability urgently, can overcome the novel anaerobic ammonia oxidation reactor of above-mentioned shortcoming simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of sequencing batch membrane bioreactor, with the long problem that reaches the environmental requirement strictness of device complexity, sludge loss, anaerobic ammonoxidation bacterium concentrating incubation time that solves present enrichment anaerobic ammonia oxidizing bacteria.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: described reactor comprises inlet chest, intake pump, magnetic stirring apparatus, the magnetic force rotor of band blade, go out water pump, water tank, very first time relay, second time relay, the water-bath ring, cylindrical synthetic glass tube, fibrous reticulum, filler, filler support, the heating rod and the 3rd time relay, inlet chest is communicated with by the water-in of intake pump with cylindrical synthetic glass tube top, the switch of first rly. control intake pump, cylindrical synthetic glass tube skin is concentric water-bath ring, the water-bath ring is arranged on the magnetic stirring apparatus, the switch of second rly. control magnetic stirring apparatus, be provided with fibrous reticulum in the cylindrical synthetic glass tube, filler, the magnetic force rotor of filler support and band blade, the magnetic force rotor of band blade is located at the bottom of cylindrical synthetic glass tube, filler support is placed on the bottom of cylindrical synthetic glass tube and is positioned at the top of the magnetic force rotor of band blade, filler support is provided with filler, filler is provided with fibrous reticulum, the water outlet of cylindrical synthetic glass tube bottom is communicated with water tank by going out water pump, the 3rd rly. is controlled out the switch of water pump, is provided with heating rod in the water-bath ring.
The present invention has following beneficial effect: apparatus of the present invention are simple in structure, and workflow is simple, and are easy to operate, can save settling tank and reflux; Good effect of separating solid from liquid, effluent quality is good, can realize mixing fully at inside reactor by the magnetic force rotor of band blade, be that ideal staticly settles during precipitation, the water content of the sludge microbe in the microbial film is low, and the aged microbial film volume that peels off is bigger, and settling property is good; Operation is flexible, can regulate each processing parameter according to the water quality situation, effectively prevents sludge bulking, anti impulsion load; Microbial film hangs on the carrier, and the residence time and dwell time of sewage are irrelevant, helps long microbial growth generation time such as anaerobic ammonia oxidizing bacteria, and the enrichment culture time is short, and the excess sludge generation is few.
