Make to purify the sewage.However, this moving bed biofilm reactor could shape only inside the lower layer of biomembrane and filler
At anaerobic environment, it is difficult to effectively raised growth denitrifying bacterium, therefore the ability for removing total nitrogen is limited.Simultaneously as polyP bacteria
It can not be recycled in aerobic section and anaerobism section such as the sludge in activated sludge process, filler can only be followed to move and inhale phosphorus and release phosphorus, no
In the presence of the sludge for excluding rich phosphorus, therefore dephosphorization effect is general, it is hard to realize under the conditions of existing urban wastewater treatment influent quality
Reach the requirement of level-one emission standard A.
On the other hand, traditional anaerobic- anoxic- oxic method（Anaerobic-Anoxic-Oxic, A2O）In technique, in work
Flora is mainly made of nitrifier, denitrifying bacterium and polyP bacteria in property sludge.In aerobic section, nitrobacteria is by the ammonia nitrogen in flow
And the ammonia nitrogen that organic nitrogen ammonia is converted to, it is acted on by biological nitration, is converted to nitrate；In anoxic section, denitrifying bacteria will be interior
The nitrate brought into flow back by biological denitrification, is converted to nitrogen and escapes into air, to achieve the purpose that denitrogenation；
In anaerobism section, the degradable organic matters such as polyP bacteria discharges phosphorus, and absorbs lower fatty acid；And in aerobic section, polyP bacteria excess
Phosphorus is absorbed, and by the discharge of excess sludge, phosphorus is removed.
However, the above process must carry out the cycle of sludge and sewage, to ensure the removal of ammonia nitrogen and the effect of dephosphorization, nothing
The operating cost for increasing sewage disposal is doubted, meanwhile, activated sludge is ceaselessly recycled in aerobic section, anaerobism section and anoxic section, good
Oxygen bacterium and anaerobic bacteria need constantly to adapt to the environment of growth, both can not whole process keep the high efficiency of bacterial degradation microorganism,
Also it is difficult to be enriched with out dominant bacteria.When especially influent ammonia nitrogen, COD contents are big, the load impact of system is increased, ammonia nitrogen is discharged
Content is sometimes exceeded, fluctuation of service, the reason is that aerobic section is inadequate to anoxic section internal circulating load, denitrification not exclusively causes.
