Abstract
The utility model relates to a moving bed biofilm reactor, including water pump, MBBR reactor, its characterized in that: the air pump and the aeration equipment of reactor are connected, aeration equipment set up middle part and bottom at the reactor respectively, the delivery port of reactor and sedimentation tank tube coupling, sedimentation tank pass through the water pump to be connected with good oxygen pond with the anaerobism pond respectively, sets up aeration equipment in good oxygen pond and the anaerobism pond respectively, log raft play after the gap in good oxygen pond directly will be handled. The utility model has the advantages of: MBBR has a better shock -resistant ability, when CODcr's volumetric loading 1-3 kg (m3 d) 11 o'clock, the clearance is stable more than 90 %, reaches 6 kg (m3 d) at 11 o'clock as volumetric loading, CODcr's clearance is more than 70 %. Simultaneously, nitrify and the anti - nitration in the good oxygen pond of the water of sedimentation tank process can effectively get rid of the nitrogen in the sewage, play purifying effect.
Description
Technical field
The utility model relates to a kind of MBBR.
Background technology
MBBR (MovingBedBiofilmReactor is called for short MBBR) is a kind of New foul water disposal facility of 20th century the mid-80 appearance.It combines activated sludge process and biomembrance process 2 kinds of techniques, core is that density is added to carrier as microorganism growth in reactor close to the floating stuffing of water, in fluidized state under the castering action of filler current in aeration and reactor, microorganism and waste water fully contact thus reach the effect of disposing of sewage.But the aerating apparatus of existing biofilm reactor is arranged on the bottom of reactor, and aeration is uneven, affects wastewater treatment efficiency.Secondly, existing reactor efficiencies of nitrogen removal is poor.
Summary of the invention
The utility model provides a kind of MBBR, comprises water pump, MBBR reactor; It is characterized in that: the air pump of reactor is connected with aerating apparatus, described aerating apparatus is separately positioned on middle part and the bottom of reactor; The water outlet of reactor is connected with settling tank pipeline, and settling tank is connected with Aerobic Pond with anaerobic pond respectively by water pump, arranges aerating apparatus respectively in Aerobic Pond and anaerobic pond, and the water after process is directly discharged by the spillway of Aerobic Pond.
The utility model has the advantage of: MBBR has good shock-resistant ability, works as COD
crvolumetric loading at 1 ~ 3kg(m
3d)
-1time, clearance is stabilized in more than 90%, when volumetric loading reaches 6kg(m
3d)
-1time, COD
crclearance more than 70%.Meanwhile, the water of settling tank reacts through the nitrification and denitrification of Aerobic Pond, effectively can remove the nitrogen in sewage, play decontamination effect improving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model provides a kind of MBBR, comprises water pump 4, MBBR reactor 3.Water in sewage lagoon is pumped into MBBR reactor by water pump, when MBBR starts, feedwater quality concentration is lower, and the air pump 4 of reactor is connected with aerating apparatus, described aerating apparatus 2,3 middle part and the bottoms being separately positioned on reactor, aeration rate is adjusted to and makes filler just fluidisation completely.On process filler in early stage, microbial film is very thin, and make its fluidisation need energy consumption comparatively large, during beginning, hydraulic detention time is longer, and therefore gas-water ratio is up to 25: 1.Along with the increase of flooding velocity, hydraulic detention time shortens, and on filler, microbial film is thickening, and now make the energy consumption of the complete fluidisation of filler diminish, gas-water ratio is approximately 10: 1 ~ 15: 1.
During MBBR reactor start-up, need to carry out biofilm to biologic packing material.Adopt sealing and circulating method during beginning, after dropping into seed sludge, the first vexed 24h that exposes to the sun, makes mud fully contact with filler, the active sludge of inoculation of then draining, then puts into the waste water of preparation continuously.Start wastewater quality concentration lower, be about 120mg/L, flow is 5mL/min, after progressively increase flooding velocity, improve organic loading, finally make suspended sludge mass concentration between 2000 ~ 5000mg/L.
The water outlet of reactor is connected with settling tank pipeline, and settling tank 5 is connected with Aerobic Pond 7 with anaerobic pond 6 respectively by water pump, and arrange aerating apparatus 9 respectively in Aerobic Pond and anaerobic pond, aerating apparatus is started by air pump 8.By arranging aerobic and anoxic 2 kinds of environment, and by inner circulating reflux, form the object that " forward type denilrification system " reaches organics removal and nitrogen.Water after process is directly discharged by the spillway of Aerobic Pond.
