Description
Technical field
The invention belongs to water treatment field, and in particular to a kind of integrated semi-hitrosation anaerobic ammonium oxidation apparatus and its work
Method.
Background technology
Traditional biological denitrogenation is the sewage denitrification method based on nitrification, denitrification.Except traditional three-level decarburization one
Nitrify outside a denitrification process, various modifieds are developed in recent years and nitrify a denitrification denitrogenation technique, including anoxic/good
Oxygen (A/O) technique, aerobic (A2/O) technique of one anoxic of anaerobism one, Bardenpho techniques (multistage A/O techniques), UCT techniques and
VIP techniques etc..These techniques have been widely used in wastewater treatment, and achieve preferable denitrogenation of waste water effect.However as
The raising of wastewater discharge standard, these techniques also expose the deficiency of itself.For example, single level system treatment efficiency is relatively low；It is multistage
System capital cost is higher;When low-carbon high-nitrogen waste water is processed, then additional carbon is needed, increased the operating cost of water factory.
Anaerobic ammonia oxidation process is proposed by Dutch Delft universities, refers under anaerobic, by specific microorganism
With NH4 +-N（Ammoniacal nitrogen）And NO2 --N（Nitrite nitrogen）Respectively as the reaction that electron donor and electron acceptor are carried out.With with nitre
Traditional denitrification process based on change, denitrification is compared, and the technique has many advantages：(1) organic matter work need not be added
It is carbon source, both saves expense, turn avoid secondary pollution；(2) oxygen demand is greatly lowered, the reduction of energy consumption operating cost；(3) by
Only just can be by ammoxidation into nitrogen with a step in Anammox reaction, therefore technique product acid in itself has been measured and has been greatly reduced,
So as to save the use of neutralization reagent.
But, used as autotrophic bacterium, the anaerobic ammonia oxidizing bacteria doubling time is long, and growth conditions is more harsh, to light and dissolved oxygen
It is extremely sensitive, in actual applications by more limitation.Further, since more difficult accumulation nitrite nitrogen under field conditions (factors) so that
The unavailable stably electron acceptor of Anammox, therefore, in handling process, before typically before anaerobic ammonia oxidation reactor
A provided nitrite nitrogen of nitrosation reactor is put, the single-stage or multi-stage process of many correlations are it is also proposed both at home and abroad.But
It is that they all have certain defect in the application.Single stage process needs ammonia oxidation bacteria with anaerobic ammonia oxidizing bacteria in a reaction
Concerted reaction is carried out in device, because the best growing condition of two kinds of bacterium slightly has difference so that condition control is more difficult, such as too high
Dissolved oxygen can suppress Anammox reaction, it is too low also to ensure that ammonia nitrogen is converted to nitrite nitrogen；Nitrite nitrogen is dense
Spend it is low matrix can be caused not enough, the growth of anaerobic ammonia oxidizing bacteria is restricted, work that is too high and can suppressing anaerobic ammonia oxidizing bacteria
Property.By contrast, although the conditional parameter controllability enhancing of second order reaction, due to influenceing the factor of each order reaction more,
Often so that the joint of two reactions is affected.
For these problems, how can respectively ensure that two kinds of domestication cultures of thalline again can be so that both can realize surely
Fixed association response is particularly important.
