Technical field
The utility model is related to a kind of novel MBBR mud film combined sewage processing systems, belong to biochemical wastewater treatment field.
Background technology
In order to strengthen activated sludge process denitrogenation dephosphorizing ability, MBBR bio-carriers can be added to aerobic activated sludge pond
In, form the biomembrane and activated sludge compound sewage processing system that activated sludge and biomembrane coexist.Mud film hybrid system has
The advantage of active sludge processes and MBBR respectively needs longer sludge age nitrification mainly unrelated in sludge age and hydraulics residence time
Biological suspension carrier on carry out, and activated sludge part is then substantially carried out oxidation and the aerobic phosphorus absorption of organic matter.Due to activity
Sludge sludge age is short, sludge bulking phenomenon is not present, therefore the settling property of sludge is excellent, and red worm is not present on MBBR suspending carriers
Equal metazoas.
Traditional AAO and oxidation ditch process, because only existing active sludge biological amount in its biological tank, denitrification percent is very limited,
In the case where influent load impact is big and temperature declines big, water outlet TN is difficult to up to standard.And MBBR mud film hybrid systems can be effective
Realization mud（Activated sludge）Film（The biomembrane adhered on MBBR carriers）Synergistic effect, can fully ensure that in different water inlets
Ensure that effluent quality is up to standard, efficiently avoids while the contradiction of denitrogenation dephosphorizing under water quality and seasonal conditions.
Utility model content
The purpose of this utility model is to provide a kind of novel MBBR mud film combined sewage processing system, this system overcomes
The limited defect of sewage disposal biochemical treatment denitrification percent, can be effectively used for the industry and municipal administration of the shapes such as oxidation ditch or circulation shape
Sewage treatment plant's biological tank carries out upgrading, it can also be used to the design of newly-built sewage treatment plant.
The technical solution adopted in the utility model is：A kind of novel MBBR mud film combined sewage processing system, including water inlet
Mouthful, water outlet and pond body, have MBBR suspended biological carriers in the pond body, setting cycle ditch shape training wall among pond body, water conservancy diversion
Pond body is separated into irrigation channel and water outlet channel by wall.
Further, setting impeller and boring aeration pipe in the irrigation channel.
Further, setting impeller and boring aeration pipe in the water outlet channel.
Further, the water outlet channel avris is provided with carrier and intercepts sieve.
The utility model has the beneficial effects that：
1）After sewage enters pond body from water inlet, sewage can circulate in pond body, after a part of biochemical reaction
Muddy water sieve intercepted by carrier flowed out from water outlet, and prodigious another part muddy water is enclosed with MBBR suspended biological carriers
It is circulated around training wall, extends the time of contact of muddy water and carrier, enhance the mixing intensity of muddy water and carrier.
2）The biomembrane that is grown on the activated sludge of pond body and the MBBR suspended biological carriers added while coexisting in biology
In pond, increase the different population microbial biomass in biological tank, can substantially improve conventional activated sludge process processing capacity and
Performance.

Wherein：1, water inlet, 2, pond body, 3, impeller, 4, training wall, 5, perforated pipe aerating regulation pipe, 6, carrier intercept sieve,
7, water outlet, 8, MBBR suspended biological carriers, 9, irrigation channel, 10, water outlet channel.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of novel MBBR mud film combined sewage processing system, including water inlet 1, water outlet 7 and pond body 2 have in pond body
MBBR suspended biological carriers 8, the pond body centre setting cycle ditch shape training wall 4, pond body is separated into irrigation channel by training wall 4
9 and water outlet channel 10.It is strong in order to increase the rate of circulating flow for extending muddy water and carrier, oxygen supply and the mixing of enhancing muddy water carrier
Impeller 3 and boring aeration pipe 5 are all set in degree, irrigation channel 9 and water outlet channel 10.In order to ensure the part after biochemical reaction
Muddy water intercepts sieve by MBBR suspended biological carriers 8 and is flowed out from water outlet 7, and prodigious another part muddy water is outstanding with MBBR
Pelagic organism carrier 8 is circulated around training wall 4, and water outlet 10 avris of channel is provided with carrier and intercepts sieve 6.
The workflow of the utility model is：
1）Pond body is flowed by water inlet by pretreated sewage, in pond body under the promotion of impeller, in pond body
Activated sludge and MBBR suspended biological carriers circulated together around training wall；In addition, being exposed in perforated pipe aerating regulation pipe
Under the action of the air gone out, activated sludge, sewage and MBBR suspended biological carriers in pond body are adequately mixed, and MBBR is outstanding
Medium well is not long and the biomembrane that falls off on pelagic organism carrier, strengthens the biochemical action of the microorganism in pond body, ensures water outlet ammonia nitrogen
Equal pollutants are up to standard.
2）Carrier, which is continued to pass through, in the part muddy water of pond body internal circulation flow intercepts sieve from water outlet outflow, and MBBR is outstanding
Pelagic organism carrier is intercepted in pond body, keeps higher biomass in pond body.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
Example one
The utility model is used for the upgrade expanding of 40,000 ton per day municipal sewage treatment AB process spent water processing ponds of a certain scale,
The disengaging water quality of sewage treatment plant's upgrading：
It is that MBBR techniques are attached in activated sludge tank using activated sludge-MBBR group technologies, the sewage treatment plant
The characteristics of transformation is：Original aeration tank A sections of and flat flow intermediate sedimentation pond transform anoxic pond and anaerobic pond as, in anoxic pond volume
In the case of insufficient, one group of anoxic pond is further added by vacant lot beside it, TN is removed for biological phosphate-eliminating and denitrification；Due to water
The increase of amount creates one group of secondary settling tank；Residence time of the sewage in the former aeration tank B sections of is too short, and nitrobacteria nitrifies needed for NH4-N
Sludge age it is inadequate, so, B sections of aeration tanks are changed to the sewage disposal system of the utility model, the utility model being transformed into
Sewage disposal system pond body product is 5760m3, and the MBBR suspended biological carriers being added in system are polyethylene hollow cylinders,
Inside has cross hang, outside to have fin, 0.95 g/cm of density2Left and right, for the effective ratio area 500 of biomembrane attachment
m2/ m3More than, in its pond, nitrification is mainly undertaken by the biomembrane on suspending carrier, greatly reduces aerobic sludge age, is saved
Pool capacity.By above modification measures, the anaerobic zone newly formed is used for dephosphorization, and anoxic zone is used for Prepositive denitrification；And it removes
The heterotroph of BOD is then mainly completed the removal of BOD by the activated sludge that the sewage disposal system of the utility model suspends；Separately
Outside, the biomembrane to fall off enters in active sludge intermixture, and can automatically generate suspension nitrifying sludge inoculation effect, enhances whole
The stability of a biomembrane and activated Sludge System anti-shock loading；Furthermore since Age of Activated Sludge is short, there is no sludge is swollen
Swollen phenomenon, biological phosphate-eliminating are realized and are strengthened by appropriate combination anaerobic zone and short sludge age aerobic zone.After trial operation 3 months
Effluent quality is：Ammonia nitrogen is less than 5mg/L, and COD is less than 35mg/l, and other indexs also fully meet Effluent criteria.
