In the present embodiment,
Anaerobic pond: reflux rich phosphorous sludge is thoroughly mixed with sanitary sewage, under strictly anaerobic environmental condition, by certain time Anaerobic digestion, remove some organic pollutants, a small amount of nitrogenous compound of water phase is converted to N2 (denitrification) and discharges, The poly- phosphorus microorganism (PAOs) of mud phase releases phosphorus, meets the needs of bacterial multiplication is to phosphorus.
Anoxic pond: reflux nitrification liquid flows into anoxic pond and mixes with the mixed liquor from anaerobic pond, under the conditions of anaerobic environment (DO≤0.5mg/L), the denitrifying bacteria of anoxic pond is using carbonaceous organic material undecomposed in sewage as carbon source, by the nitrification liquid that flows back The a large amount of NO3- carried are reduced to N2, head space release.The denitrification phosphorus-collecting microorganism (DPAOs) of mud phase is absorbed using anaerobism section COD and formed PHB a part supply it is denitrifying simultaneously, another part be configured to anoxic inhale phosphorus.In addition, there is part in anoxic pond Micro- oxygen, part TP is under the effect of facultative microbe H3P reducing bacteria, gasification finish.
Aerobic membrane cisterna: under complete aerobic condition (DO=2 ~ 4mg/L), the COD in water phase is decomposed under heterotrophic bacteria group effect For CO2 and H2O.NH3-N in water phase generates NO3- under nitrifier effect, while the oxidation operation in water phase decomposes supply Phosphorus microorganism energy is inhaled, phosphorus formation ATP or ADP is excessively inhaled from water and enters cell tissue, is enriched in microbial body;Again through film Component solid-liquor separation is discharged from system in the form of rich phosphorous sludge, reaches biological phosphate-eliminating purpose.It is driven in the gravity for producing water pump auxiliary Under dynamic, water outlet imports discharge bay.As needed, qualified discharge or safe reuse.
The sewage-treatment plant, it is easy to operate, convenient for management, take up little area, be with low investment, operating cost it is low;It avoids and reduces Secondary pollution;There are biggish flexibility, adjustability, to adapt to the fluctuating change of water, water quality.Membrane module is flat using A2O-MBR Plate membrane process cracked traditional A2O technology process using hollow membrane MBR and other plate membrane MBR as core integration apparatus " from Line cleaning operation too complex " can not be in the long-term running problem in villages and small towns area.It is acted on by the mechanical grading of membrane module, A2O- The decoupling regulation of hydraulic detention time (HRT) and sludge retention time (SRT) may be implemented in MBR technique, fundamentally solves tradition A2O technique biological denitrificaion and " releasing phosphorus-suction phosphorus " recycle the inner contradictions relied on SRT, really realize TN, TP stably reaching standard.Separately Outside, high performance membrane group almost 100% prevents generation cycle long nitrifier and heterotroph bolus flow and loses, and is obviously improved TCA, EMP, N- The biochemical degradations such as dN, dP process, rate and efficiency, effluent index not only meet the minimum pressure demand of qualified discharge comprehensively, and Its main indicator can reach " water environment quality standard " (GB3838-2002) IV class require can direct reuse, simply Change intensive structure design, the more traditional A of occupied area2O technique reduces 50% or more, is particularly suitable for the Urban Areas of land used anxiety.
Above-described embodiment can be seen that the utility model with following obvious advantage:
(1) the long-term stably reaching standard of TN, TP uses A2O-MBR technique fundamentally releases and solves tradition A2O technique biology is de- Nitrogen and " releasing phosphorus-suction phosphorus " recycle the inner contradictions relied on SRT, independent regulation denitrogenation and dephosphorization process, really realize that TN, TP are normal Year stably reaching standard is better than the level-one A of GB18918;
(2) the high tradition A of contamination index's removal efficiency2O technique biological tank operates in the area 3000 ~ 5000mgMLSS/L mostly Between, decentralized integrated sewage treatment device biological tank then operates in the section 10000 ~ 20000mgMLSS/L, that is, A2O work 2 ~ 4 times of skill!Higher sludge concentration is obviously improved the efficiency of pollutant bioconversion degradation, the removal rate of each contamination index It greatly improves, main indicator all the period of time is better than the ground Table IV class of GB3838;
(3) occupied area is small, and when saving space biological treatment high-concentration waste water, concentration for the treatment of is higher, needs treatment trough Size is bigger.Using A2O-MBR technique can be operated, it is possible to significantly under high loads due to sludge concentration height It saves floor occupying area;
(4) the high plate membrane of stable effluent quality, transparency can retain almost all of microorganism, especially be difficult to precipitate , the microorganism that growth rate is slow, therefore the biology in system is by extreme enrichment, activated sludge acclimatization, increment process significantly Shorten, the shock proof ability of depth and system of processing is enhanced, and effluent quality is highly stable;
(5) operational management is convenient, safeguards simple tradition A2The high sludge loading operating condition operation of O technique, inevitably occurs Sludge bulking phenomenon, cause to operate normally for a long time, be discharged it is not up to standard.And A2O-MBR technique is carried out by the suction of film Mud-water separation, therefore, influence of the sludge bulking to water outlet are much smaller than tradition A2O technique has operational management very convenient, automatically Change degree is high, safeguards outstanding advantages of simple;
(6) SRT long A2The UF membrane of O-MBR technique makes the ingredient difficult to degrade of the macromolecular in sewage, in the life of finite volume Possess enough residence times in object pond, substantially increases the degradation efficiency of hardly degraded organic substance.Biological tank high volumetric loading, It is run under the conditions of low sludge loading, long sludge age, excess sludge emission reduction may be implemented.Due to SRT long, it is more suitable time long micro- Biological growth is conducive to remove organic substance difficult to degrade in sewage;
(7) capacity of resisting impact load is by force when having large change in the amount of inlet water short time, it may be considered that the short time increases Film is impacted by flow with achieving the purpose that alleviate.When influent quality variation, since biological tank has higher sludge concentration, It also can achieve the purpose for alleviating impact in a certain range.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art The other embodiments being understood that.
