Description
Technical field
The utility model is used for purifying water process technical field, particularly relates to a kind of UCT-MBR coupling sewage-treating reactor.
Background technology
The treatment process of membrane bioreactor (Membrane Bioreactor-MBR) is an emerging water technology, is the combination of traditional wastewater biological treatment and membrane separation technique, is successfully applied to sewage disposal.Membrane bioreactor is generally made up of membrane separation assemblies and bio-reactor two portions, and general membrane bioreactor is placed in bio-reactor by membrane module, by isolating the active sludge of high density, usually can reach higher COD clearance.On the other hand, in order to prevent the pollution of membrane module, need to adopt larger tolerance to purge membrane module surface, also continuous being filled with oxygen in the muddy water mixed solution in reactor while purging, this just easily causes the dissolved oxygen in reactor higher, if desired carry out the process of dephosphorization, denitrogenation, just cannot reach desirable anaerobism, anaerobic environment in bio-reactor, have impact on the effect of dephosphorization, denitrogenation greatly.
UCT (University of Cape town) technique is a kind of denitrification dephosphorization technique that Cape Town, RSA university proposes, and is a kind of A of improvement
2/ O technique, in this technique, anaerobic pond carries out release and the ammonification of phosphorus, and anoxic pond carries out denitrification denitrogenation, and Aerobic Pond is with removing BOD, absorbing phosphorus and nitrated.Due to A
2the NO of returned sluge in/O technique
3-N is back to anaerobism section, disturbs the anaerobism release of phosphorus in polyP bacteria cell paste, reduces the clearance of phosphorus, Nitrogen/Phosphorus Removal is difficult to further improve.In order to overcome this situation, first returned sluge is back to anoxic section by UCT technique, the NO that returned sluge is taken back
3anoxic section by denitrification denitrogenation in anoxic section, is then gone out to flow mixed solution part and is back to anaerobism section again by-N.It is very low that denitrification due to anoxic pond makes anoxic mixed-liquor return bring the nitrate concentration of anaerobic pond into, doing so avoids NO
3-N releases the interference of phosphorus to anaerobism section polyP bacteria, the function of anaerobic pond is not fully exerted, has both improve the clearance of phosphorus, do not affect again the efficiency of denitrogenation.
In application MBR technical finesse sewage process, can by UCT technique and the coupling of MBR technique, but the problem in MBR treatment process still exists, namely in order to prevent the pollution of membrane module, need to adopt larger tolerance to purge membrane module surface, also continuous being filled with oxygen in the muddy water mixed solution in reactor while purging, this just easily causes the dissolved oxygen in reactor higher, if desired the process of dephosphorization, denitrogenation is carried out, just cannot reach desirable anaerobism, anaerobic environment in bio-reactor, have impact on the effect of dephosphorization, denitrogenation greatly.
