Row high concentration nitrate denitrogenation of waste water is the important process in sewage treatment.
Traditional biological denitrogenation is by denitrification process, i.e. denitrifying bacterium utilizes biodegradable organic matter by nitrate
Nitrogen and nitrite nitrogen are reduced to nitrogen completely, to achieve the purpose that sewage water denitrification, while can also remove the COD of part.
But for the processing of the denitrification of high-nitrate state nitrogen waste water, the anoxic pond of very big occupied area is not only needed, but also due to high in system
The presence of the nitrate of concentration inhibits the reduction of nitrite, and nitrate reduction rate is caused to be greater than nitrate reductase speed
Rate, and then nitrite can be caused to accumulate in systems, and the accumulation of nitrite nitrogen concentration, it in turn again can be to denitrification
Reaction cause to inhibit, this feedback inhibition can not be released by effective ways, still, in anaerobic denitrification system can by compared with
The measures such as the reflux of large scale are controlled, and above-mentioned inhibiting effect can be released, to improve denitrification efficiency.
Anaerobic reactor has the characteristics that load is high, occupied area is small, operating cost is low, the technique of anaerobic denitrification due to it
Also increasingly by the favor of correlative study.By studies have shown that in anaerobic denitrification system, although there is denitrification and producing first
The coupled problem of alkane (i.e. due to the presence of nitrate anion, causes oxidation-reduction potential to be in a high position, is unfavorable for the work of methanogen
Property;The NO being metabolized in denitrification processXCompound has certain inhibiting effect to methanogen;Denitrifying bacterium and methanogen pair
Have competitive relation in carbon source), still, it may be implemented than measures such as control, the reflux of larger proportion in anti-nitre by reasonable C/N
Methane phase while change.High concentration nitrate waste water is handled using anaerobic denitrifying, is a kind of economy for solving denitrogenation of waste water, has
The new way of effect.
