Abstract
The utility model relates to a moving bed biofilm reactor, including intake chamber, aeration tank, sedimentation tank, its characterized in that: the intake chamber passes through the measuring pump and is connected with the aeration tank, the air -blower passes through gas flow and aeration union coupling, the aeration tank in fill and to have the filler, aeration tank upper portion is provided with the sieve, sets up porosely on the sieve, the aeration tank is connected with the sedimentation tank, be provided with the apopore on the sedimentation tank, the sedimentation tank bottom is provided with the sludge pump for with return sludge to aeration tank, the sedimentation tank bottom is provided with the mud fill for regularly discharge mud. The utility model has the advantages of: organic loading the sludge bulking phenomenon can not appear, does not need return sludge yet, can move under higher organic loading. After biomembrane thickened on packing, the mud of aeration tank increased, COD's clearance reached 82%. Simultaneously the utility model discloses the capital expenditure is little, and the working costs is low, is the processing method of a high efficiency, economy.
Description
Technical field
The utility model relates to a kind of MBBR.
Background technology
MBBR (movingbedbiofilmreactor, be called for short MBBR) be a kind of novel, efficient sewage treatment facility, compared with traditional aerobic treatment process, there is lot of advantages, as not easily blocked, without the need to back flushing, head loss is little, organic loading is high, do not need sludge reflux etc. MBBR applying flexible, can run under the various conditions such as aerobic, anaerobism, both can be used alone, also can plural serial stage when carrying out denitrogenation aerobic treatment, be generally used for organic concentration and all higher occasion of organic loading.What the method for existing process sewage of low concentration generally adopted is contact oxidation method or biological filter, and the clearance of total COD is lower.
Summary of the invention
The utility model provides a kind of MBBR, comprises inlet flume, aeration tank, settling tank, it is characterized in that: inlet flume is connected with aeration tank by volume pump; Gas blower is by gas flow and be connected with aeration tube; Filler is filled with in described aeration tank; Top, aeration tank is provided with sieve plate, sieve plate is arranged porose; Aeration tank is connected with settling tank; Settling tank is provided with posticum; Be provided with sludge pump bottom settling tank, for by sludge reflux to aeration tank; Sludge bucket is provided with, for regularly being discharged by mud bottom settling tank.
The utility model has the advantage of: organic loading there will not be sludge bulking phenomenon, does not also need sludge reflux, can run under higher organic loading.When the microbial film on filler is thickening, after the mud of aeration tank increases, the clearance of COD reaches 82%.Initial cost of the present invention is little simultaneously, and working cost is low, is a kind of efficient, economic treatment process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model comprises inlet flume 1, aeration tank 4, settling tank.Sewage is injected in aeration tank by volume pump 2, is processed under the effect of carrier biofilm and suspended sludge microorganism.Water outlet and suspended sludge enter settling tank 6 through guide shell, and supernatant liquor is discharged by overflow port 7, are back to aeration tank or direct outer row after in sludge settling to sludge bucket by volume pump.Gas blower is connected with boring aeration pipe 3, carries out aeration to aeration tank.
In initial reaction stage, if waste strength is lower, aeration rate is adjusted to and is just made the complete fluidisation of filler.When processing the sewage of higher concentration, there is the suspended sludge of high density and a large amount of carrier biofilms in MBBR simultaneously, and can make to maintain in reactor higher is biomass, thus obtains good treatment effect.
A kind of microbial film treatment process of sewage of low concentration, closed cycle method is adopted in the utility model, after inoculation of activated-sludge, first the vexed 48h that exposes to the sun, then starts to add sanitary sewage with the flow of 1L/h, carries out sludge reflux simultaneously, shorten hydraulic detention time gradually, improve organic loading, get rid of a part of excess sludge every day, in maintenance MBBR, suspended sludge mass concentration is at 2 ~ 4g/L.
Adopt the utility model, during process low concentration wastewater, hydraulic detention time can be reduced to 1.3 hours, the volume ratio of air water is 4:1, and energy consumption is suitable with conventional activated sludge process, and COD clearance is about 80%.There is suppression relation in the suspended sludge produced during MBBR runs and carrier biofilm, therefore strengthens the aperture of water outlet sieve plate 5, prevent suspended sludge excessively rapid growth.
Claims (1)
1. a MBBR, comprises inlet flume, aeration tank, settling tank, it is characterized in that: inlet flume is connected with aeration tank by volume pump; Gas blower is by gas flow and be connected with aeration tube; Filler is filled with in described aeration tank; Top, aeration tank is provided with sieve plate, sieve plate is arranged porose; Aeration tank is connected with settling tank; Settling tank is provided with posticum; Be provided with sludge pump bottom settling tank, for by sludge reflux to aeration tank; Sludge bucket is provided with, for regularly being discharged by mud bottom settling tank.
