Description
Technical field
The utility model relates to Environmental Biotechnology, specifically is the device that a kind of fast enriching propagation and purifying are cultivated anaerobic ammonia oxidizing bacteria.
Background technology
The nineteen ninety-five people have just found the existence of anaerobic ammonium oxidizing bacteria first.Different fully with nitrated-denitrification biology that people before are familiar with, this newfound ancient type bacterium is a kind of chemosynthetic autotroph bacterium, finish denitrogenation with a kind of novel pathways metabolism, under anaerobic namely, be electron donor with the ammonia nitrogen, nitrite nitrogen is as electron acceptor(EA), the final nitrogen that generates, the chemical energy that discharges in this process, is used for carrying out the fixing of inorganic carbon, and finishes other vital movement processes as the energy by this bacterium.Under the condition of using the Anammox denitrification process, only ammonia nitrogen only about half of in the waste water need be oxidized to nitrite nitrogen, react with half ammonia nitrogen of residue then and generate nitrogen and escape into atmosphere, thereby compared to traditional nitrated-denitrification biological denitrogenation technology, the Anammox denitrification process can reduce the supply of oxygen in a large number can finish biological denitrification process.In addition, because anaerobic ammonium oxidizing bacteria belongs to chemoautotrophy type bacterium, and ammonia nitrogen is by the nitrite nitrogen oxidation, the energy density of the reaction of common formation nitrogen is very low, the bacterial growth division is extremely slow, thereby make the Anammox denitrogenation not only not need additionally to add organic carbon source, and surplus sludge volume significantly reduces compared to traditional technology, even to keep sufficient sludge quantity under many circumstances be a normal work to do keeping the Anammox reaction, has to adopt special measure and technology to accelerate the fast breeding of anaerobic ammonium oxidizing bacteria for obtaining excess sludge sometimes.
The technology that the Anammox biological denitrification process is low as a kind of working cost, efficient is high more and more is subjected to the attention of countries in the world, and has carried out big quantity research.Finally move success though spent about 3 years based on first actual engineering of anaerobic ammonia oxidation process, also there is actual engineering to put into operation in succession on Germany, Japan, Australia and other places afterwards, but initial startup mud derive from Holland mostly first move the Rotterdam sewage work of this technology success, but the many practical problemss in this process application are still perplexing the research and development personnel of countries in the world.Enrichment anaerobic ammonium oxidizing bacteria and carry out fast breeding and purifying from the provenance that nature very disperses wherein, quantity is big, the high reactor seed sludge of purity is first difficult problem that people at first run into for production practice provide.
The microorganism of the aerobic and anaerobic ferment process before anaerobic ammonia oxidation microbiological is different from, itself will spend the plenty of time enrichment of microorganism, and this bacterial multiplication speed is very slow, and the startup of reactor often needs to expend the plenty of time.Particularly running into when this bacterium produced the material of toxic action, biological reactions rates reduces rapidly, even stop, in this case, if can not in time find, will cause a large amount of accumulation of nitrite nitrogen, thereby bacterium is produced toxic action, finally cause the failure of reactor operation, even the fresh mud of the renewed vaccination of having to restarts.So fast enriching, and can breed in a large number and purifying anaerobic ammoxidation activity mud, be that this process application and research need the at first problem of solution.
People reach the purpose that research and production application anaerobic ammonium oxidizing bacteria remove in the water too much nitrogen; at first be will be from the anaerobic ammoxidation activity mud of occurring in nature enrichment, purifying, propagation sufficient amount; so that its can be fast a large amount of unnecessary nitrogens of high nitrogenous water that go out are avoided the threat that body eutrophication pollutes with the protection receiving water body.But the method that many researchs all adopt the aerobic sludge sewage of direct usefulness, anaerobism sewage disposal granule sludge or sediment of pond to start reactor starts experimental Anammox denitrification reactor, though but also can carry out the Anammox denitrification process in the reactor this moment, but the content of anaerobic ammonium oxidizing bacteria is all lower in the reactor mud, and total amount of sludge is also fewer, thereby can not satisfy large-scale reactor to the needs of anaerobic oxidation denitrification activity mud, can't be applied to produce.
Chinese patent application book CN102145940A discloses " a kind of device and method of fast breeding anaerobic ammonia oxidizing bacteria " (1), CN102061281A discloses " utilizing the method for membrane bioreactor enrichment culture anaerobic ammonium oxidizing bacteria " (2), CN101735947A discloses " a kind of soil anaerobic ammonoxidation bacterium concentrating system of simulating natural environment " (3), these methods or be conceived to the fast breeding of anaerobic ammonia oxidizing bacteria, i.e. its inoculation be a small amount of anaerobic ammonium oxidizing bacteria (1) that enriching and purifying is good; Be with membrane bioreactor enrichment culture anaerobic ammonium oxidizing bacteria, the anaerobic ammonium oxidizing bacteria of dispersion is enriched on the film, improved bioaccumulation efficiency significantly, structure for membrane bioreactor there is no particular requirement, and the quantity of the anaerobic ammonium oxidizing bacteria that obtains and purity have much do not guarantee (2); Or with earth pillar enrichment anaerobic ammonium oxidizing bacteria anaerobic ammonium oxidizing bacteria is enriched in the earth pillar, be difficult to problem that the bacterium of enrichment is separated but after enrichment is finished, exist, can not obtain directly, easily all that quantity is big, the higher anaerobic ammoxidation activity mud of purity, thereby have certain restriction in actual applications.
