The upper port of biofilter 5 is equipped with water outlet 15.The top of the biofilter 5 is equipped with sterilization pool 10.In the sterilization pool 10
It, can be to treated water carries out disinfection processing equipped with disinfection tank 11.
It is connected by stripping reflux pipe 13 between aerobic 4 end of the ponds MBBR, biofilter 5 and the oxygen pond 2 that disappears, and
The top setting air lift outlet pipe 12 of biofilter 5.
In the present embodiment, disappear 1, oxygen pond reactive tank, 1 reactive tank of anaerobic filter, 1, the aerobic ponds MBBR reactive tank, biology
1, filter tank reactive tank, 1 reactive tank of sterilization pool, residence time be respectively：3h, 6h, 8h, 2h, 0.5h.It is set in the oxygen pond that disappears
It is equipped with the oxygen filler that disappears, filling rate 10-50%.The anaerobic filter is provided with anaerobic filter filler, filling rate 10-50%.Institute
It states the aerobic ponds MBBR and is provided with MBBR Active biological fillers, filling rate 10-50%.The biofilter is provided with filter tank filler,
Filling rate 10-50%.The product of Patent No. ZL200610096315.6, diameter can be selected in the MBBR Active biological fillers
For 10-25mm, proportion 0.96-0.98；Porosity 94%-96%.The areas Xiao Yang and anaerobic filter area are not provided with agitating device；
The aerobic areas MBBR are equipped with aerator, ensure the effective supply of oxygen.The aerobic areas the MBBR end, biofilter and the oxygen that disappears
Stripping reflux device is respectively equipped between area, it can be by the aerobic areas MBBR end and biofilter area mixed-liquor return to anaerobic filter
Area.
As shown in the scheme one in Fig. 3, sanitary sewage enters regulating reservoir after fine fack, and boosted pump or gravity flow, which enter, to be detested
Oxygen filter tank flows into interconnected anaerobic filter, the aerobic ponds MBBR and biofilter, is partly refluxed to the oxygen pond that disappears, part successively
Outer row after being sterilized into sterilization pool.Scheme two in Fig. 2 is to enter the oxygen pond that disappears by flowing automatically by sewage after septic tank.
As shown in Fig. 2, the treatment process of the utility model is：
In the oxygen pond that disappears, the dissolved oxygen to come from the mixed liquor band of the water outlet of the aerobic ponds MBBR and biofilter precipitating sludge is filled
Divide consumption and utilize, ensures that anaerobic filter bed denitrification is normally carried out, further nitration reaction is carried out while disappearing oxygen；Disappear
The sludge liquid that solution reflux comes provides carbon source for denitrification denitrogenation, carries out part denitrification denitrogenation；It especially intakes intermittent feelings
Under condition, in the oxygen pond that disappears, the excess sludge accumulated after being cleared up under aerobic environment provides carbon source for denitrification.
In anaerobic filter bed, microorganism is in anaerobic condition, and microorganism is aerobic-anaerobic microbe at this time, they are by having in sewage
Machine
-- ammonia nitrogen is resolved into nitrogen conversion, while using the organic carbon in sewage as electron donor, by the NO in sewage2-
N、NO3- N is converted to N2, but also utilize part organic carbon source and NH4 +- N synthesizes new cellular material.So anaerobic filter bed is not
Only have the function of certain organic matter removal, mitigates the organic loading in the follow-up aerobic ponds MBBR, in favor of the progress of nitrification,
But also denitrification is completed by the organic matter of higher concentration present in sewage, the final eutrophication for eliminating nitrogen is dirty
Dye；
In the aerobic ponds MBBR, since organic concentration has been greatly lowered, but still there is a certain amount of organic matter and higher
Ammonia nitrogen exists, and in order to make organic matter obtain further oxygenolysis, and ensures that nitrification can be smoothed out, in aerobic MBBR
The lower aerobic biochemical system of organic loading is arranged in pond, and heterotroph microorganism and the micro- life of autotrophic type are primarily present in the aerobic ponds MBBR
Object (nitrifier), wherein organic matter is resolved into CO by heterotroph microorganism2And H2O, autotrophic type microorganism (nitrifier), which utilizes, to be had
Machine object decomposes the CO in the inorganic carbon generated or air2As nutrient source, by the NH in sewage4 +- N is converted to NO2 --N、NO3 --
N, the aerobic ponds MBBR effluent recycling provide electron acceptor to the oxygen pond that disappears, for anaerobic filter bed, are finally eliminated by denitrification
The pollution of nitrogen, to reach BOD, COD, NH in final removal sewage4 +The purpose of the pollutants such as-N, total nitrogen, total phosphorus.Sewage is through life
It is precipitated and is filtered into biofilter after object processing, the SS in sewage is removed, the oxygen pond that disappears is partly refluxed to, is passed through behind part
Enter artificial swamp or direct emission after disinfection.
The treatment process of the utility model has following features：
(1) process advantage：Processing capacity is strong, stable effluent quality, ensures the sporadic change of effluent quality water, water quality
Change.
Technology in technique：1. aerobic tank is compared using MBBR techniques with common contact oxidation technology, biomembrane is easier to
Update；2. nitrification liquid enters anaerobic filter after the oxygen that disappears, has and utilize denitrification；3. replacing the sedimentation basin residence time using filter tank
Short, water outlet SS is relatively low.
(2) process advantage：Capacity of resisting impact load is strong, can resist pulsed water inlet, sporadic a large amount of water inlets, water quality it is prominent
The variation of hair property.
Technology in technique：Main body is biomembrane process, and biomass is big, and type is abundant, and capacity of resisting impact load is strong.
(3) process advantage：Floor space is small, small investment.
Technology in technique：1. biomembrane process floor space is small；2. exempting to backwash filter tank instead of sedimentation basin, reduces and account for
Ground.
(4) process advantage：Sludge quantity is few, and operation and maintenance interval time is long, and O＆M cost is low.
Technology in technique：1. it is few that biomembrane process produces mud；2. residual sludge reflux to anaerobic filter digests, further subtract
Few sludge yield.
