Description
Technical field
Utility model is related to technical field of sewage, more particularly to a kind of heterotrophism short distance nitration of matching Anammox
System, suitable for providing electron acceptor nitrite nitrogen for short-cut denitrification technique or anaerobic ammonia oxidation process(NO2 --N).
Background technology
Anaerobic ammonia oxidation process is also known as Anammox techniques, its principle is to control nitrifying process in the nitrite stage
And it is short distance nitration to terminate, then Anammox bacterium under anaerobic(AnAOB)With NO2 -As electron acceptor by NH4+Directly
It is oxidized to N2, it is the most short biological denitrificaion approach being currently known.Compared with complete nitrification-anti-nitration reaction approach, have aerobic
Low, the characteristics of nitric efficiency is high and does not need additional COD is measured, there is apparent advantage at energy-saving aspect.Currently, technique is
Actual sewage through being successfully applied to the high nitrogen low-carbon such as sludge liquid, landfill leachate handles and obtains preferable effect.However
NO as oxidant2 -It needs pre- to first pass through NH4 +Short distance nitration obtain.However realize short distance nitration steady in a long-term always
It is one of the difficult point in denitrogenation of waste water technology.
Short-cut nitrification technology uses enriching ammonia oxidation bacteria at present(AOB)And inhibit nitrite nitrogen oxidation bacteria(NOB)The side of growth
Formula realizes NO2 -The accumulation of-N mainly has following several respects problem:(1)Short sludge age is utilized under high temperature(SRT)Selective enrichment
AOB and the mode for washing away superseded NOB is only applicable to the relatively low situation of sewage load because high temperature needs to consume a large amount of energy
Source.(2)Low dissolved oxygen(DO)Inhibit NOB activity that can then lead to low denitrification percent, this external system is in for a long time under low dissolved oxygen state,
Activated sludge is easy disintegration and filamentous bulking.(3)Utilize free ammonia(FA)Although inhibiting the mode of NOB that can obtain the NO at initial stage2 --
N is accumulated, but since NOB may gradually adapt to high FA concentration, effect cannot maintain for a long time.In addition, FA can also be right
Anammox bacterium generate inhibiting effect, and the removal rates of system is caused to decline.In addition to this, waste water more or less all contains a certain concentration
Organic matter, this so that the growth of the AOB of autotrophic type can be influenced by heterotroph.
There are these above-mentioned disadvantages for short-cut nitrification technology based on autotrophy nitrococcus, have scholar to attempt with energy significantly at present
Realize NO2 -The heterotrophism nitrococcus of-N accumulation completes short distance nitration reaction instead of autotrophy AOB.However current heterotrophism nitrococcus
Realize the NO of short distance nitration accumulation2 -- N concentration is limited, and highest accumulated concentrations are only 30.1mg/L(Water inlet NH4 +- N is a concentration of
100mg/L), and not matching technique.
RO reverse osmosis technologies are that the solvent in solution is made to separate by reverse osmosis membrane with enough pressure, direction with
Infiltration direction is on the contrary, mainly separation object is the ion range in solution.The hyperfiltration more than osmotic pressure can be used to be divided
From, purification and concentrate solution.And anion-exchange membrane has selective penetrated property effect to anion, generally with-NH3 +、-NR2H+
Or-PR3 +Active exchange groups are used as Deng cation, and OH- is generated as carrier, by anion-exchange membrane in cathode
Selective penetrated property effect be moved to anode.
