Description
Technical field
The invention belongs to water-treatment technology field, particularly a kind of ammonia oxidizing bacteria based on mesh carrier is fixedChange fixed type biological active filler preparation and application.
Background technology
Now, ammonia and nitrogen pollution problem is more and more serious, and ammonia nitrogen becomes 12 and reduces discharging new binding target, promotesThe ammonia and nitrogen pollution level of preventing and treating becomes the necessary behave that improves quality of water environment. At present, ammonia nitrogen waste water treatment method dividesFor three major types, physico-chemical process, biochemical process and advanced oxidation processes. Biochemical process is due to technical maturity, stable performance, quiltBe known as is a kind of economy, effective and the most rising method. Biochemical process comprises activated sludge process and biologyEmbrane method. In traditional activated sludge process, keep amount of bacteria by sludge reflux, want to obtain high efficiency and just must increaseLarge capacity of returns keeps high bacterial concentration, will cause like this operating cost to rise, obviously unactual. In addition,The generation cycle of nitrobacteria is long, and increment speed is slow, causes in reactor nitrobacteria concentration low, treatment effeciencyBe difficult to improve. Be subject to seasonal effect large. Summer temp raises, and biochemical speed is fast, and to winter, the large portion in the northPoint Sewage Plant all can face thread microbial sludge bulking problem, causes nitrifier to be run off, and then causes water outletAmmonia nitrogen exceeds standard. Therefore, can consider that applying biological embrane method makes up the shortcoming in activated sludge process, but biomembraneMethod has problems equally, and for nitrobacteria, poor due to self film forming ability, the natural membrane time veryLong, and natural membrane non-selectivity, is difficult to form highdensity flora advantage. Various reasons shows, passesSystem biochemical process cannot reach efficient nitrification efficiency.
Nitration reaction is that ammonia oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) acting in conjunction complete, ammonia nitrogen is oxidized to sub-nitrogen by AOB, and sub-nitrogen is further changed into nitre nitrogen by NOB. Short distance nitration claims again AsiaNitrated, this technique can reduce 25% nitrated oxygen demand, 40% denitrifying carbon source, 50% sludge yield andDenitrification pool volume.
Microbial cell immobilization technology can increase substantially microorganism concn, makes microorganism be difficult for running off, contractingShort reaction device start-up time, mithridatism and acid and alkali-resistance, salt resistance ability obviously strengthen, can purifying and to create characteristic thinThe ecological dominance of bacterium, produces characteristic highly effective reaction, has a good application prospect. What microbial cell was conventional consolidatesDetermining method has absorption method, cross-linking method and investment. Wherein, the most conventional with investment, be successfully used toThe material of microbial cell embedding has: polyvinyl alcohol, agar, K ?carragheen, gelatin, sodium alginate, poly-thirdAlkene acid amides, polyurethane etc. Above-mentioned embedded material has microorganism nontoxicity, mass-transfer performance is good, difficult is given birth toThe features such as thing decomposition, stable in properties, mechanical strength is high, the life-span is long, price is low.
At present, traditional bacterium embedding method is that bacterium and embedded material are combined, and forms embedding body,Such as microballoon, embedded block etc. The method is simple to operate, but limitation is large, cannot ideal application to engineering realityIn the middle of. We,, through research for many years, improve on traditional embedding method, and embedding body is combined with carrierTogether, form overall biological active filling material. Due to the combination of embedding body and carrier, make biologically activeFiller has more performance, and it has inherited all advantages of original simple bacterium and embedded material; Due to carrierThe application of material makes biological active filling material have the characteristic that various carriers have, and for example specific area is large, difficultThe advantages such as obstruction. Experimental study shows, utilizes existing Raschig ring, Pall ring, cascade ring, suspension modified filling outThe conventional carriers such as material and embedding body combine by adhesion mode the biological active filling material making and all have entiretyPoor stability, embedding body easily comes off, and causes the problems such as bacterium loss.
For the problems referred to above, the immobilized biological activated filler that it is good that we develop a kind of resistance to overturning has extensivelyGeneral application prospect.
Summary of the invention
The object of the invention is to develop a kind of fixed life of ammonia oxidizing bacteria immobilization based on mesh carrierThing active filler, the network structure design of this biological active filling material carrier, makes embedding body by mesh and carrier shapeBecome overall rivet clasp structure, embedding body difficult drop-off, and embedding physical efficiency forms millimetre-sized on network structureMembrane structure, makes the biological active filling material resistance to overturning that makes good, and overall permeability is good, and mass transfer effect is higher.In addition, biological active filling material is fixed in reactor by frame structure supporter, and filler can not run off with current,Treatment effect is stable.
