The bio membrane process of widespread use at present has bio-aeration filter bed, blodisc, bio-contact oxidation bed.And the bio-aeration filter bed makes operation miscellaneous because of the regular backwash of need.Though the bio-contact oxidation bed has solved the sludge bulking phenomenon, biologic packing material will regularly replace, and needs to increase mud backflow PWR PLT.Develop a kind of high-efficient biological reactor for this reason the raising that practical engineering application is worth is had far reaching significance.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, and a kind of pulling flow type inner loop three phase fluidized bed reactor of highly economical is provided.
The described pulling flow type inner loop three phase fluidized bed reactor of the utility model is made up of pond body, influent weir, effluent weir, flow deflector, lonely shape cowling panel, water outlet cowling panel and aerating apparatus; Chi Tiwei is upwards uncovered; By party wall it is divided into first step inner loop three phase fluidized bed reactor and second stage inner loop three phase fluidized bed reactor; Influent weir is positioned at the top, top of first step inner loop three phase fluidized bed reactor, and the influent weir bottom connects water inlet pipe, and effluent weir is positioned at the second stage inner loop three phase fluidized bed reactor upper end water surface; The effluent weir bottom connects rising pipe; The crest of weir of influent weir is higher than the crest of weir of effluent weir, and party wall is lower than the crest of weir of effluent weir, and flow deflector, lonely shape cowling panel, water outlet cowling panel vertically are fixedly connected with the front and back inwall of first step inner loop three phase fluidized bed reactor and second stage inner loop three phase fluidized bed reactor respectively; Lonely shape cowling panel and water outlet cowling panel are positioned at the flow deflector top; Aerating apparatus is a microporous pipe, is many, and crosswise fixed is in the bottom of first step inner loop three phase fluidized bed reactor and second stage inner loop three phase fluidized bed reactor.
Structural principle:
The utility model is through party wall the pond body to be separated into first step inner loop three phase fluidized bed reactor and second stage inner loop three phase fluidized bed reactor, through increasing party wall, can increase the progression of biological fluidized bed.Intake continuously through influent weir, the liquid level of first step inner loop three phase fluidized bed reactor is got a promotion, cross party wall, realize the water body plug-flow.In first step inner loop three phase fluidized bed reactor and second stage inner loop three phase fluidized bed reactor, can fill ceramsite carrier.Establish aerating apparatus in the bottom respectively in the biological fluidized bed; Be separated into stage casing aeration lifting zone and recirculating zone, two ends with flow deflector; Under the liquid level of aeration lifting zone top lonely shape cowling panel is set, utilizes gas-liquid to promote power and change the liquid movement direction, improve liquid internal recycle speed.
The described pulling flow type inner loop three phase fluidized bed reactor of the utility model is rational in infrastructure, makes fluidizing performance good, and the most of carrier of reactor drum participates in circulating, and does not therefore have carrier demixing phenomenon in the bed.The suffered friction in bed of each carrier, shear basic identically, the carrier fluidisation has good homogeneous property, and this forms the condition that provides for uniform microbial film.Some tiny bubbles are carried in simultaneously a large amount of liquid circulation meetings secretly, and solution-air is prolonged duration of contact, thereby have improved the transfer efficiency of oxygen, make construction costs and running cost greatly reduce.

Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structural principle synoptic diagram.
Among the figure: 1-pond body, 2-influent weir, 3-effluent weir, 4-flow deflector; The lonely shape cowling panel of 5-, 6-water outlet cowling panel, 7-aerating apparatus, 8-first step inner loop three phase fluidized bed reactor; 9-second stage inner loop three phase fluidized bed reactor, 10-water inlet pipe, 11-rising pipe, 12-party wall.
Embodiment
Embodiment:
As shown in the figure, present embodiment discloses a kind of secondary pulling flow type inner loop three phase fluidized bed reactor.
Described pond body 1 is the uncovered shape that makes progress, and by party wall 12 it is divided into first step inner loop three phase fluidized bed reactor 8 and second stage inner loop three phase fluidized bed reactor 9, increases the progression of biological fluidized bed through increasing party wall.Influent weir 2 is positioned at the top, top of first step inner loop three phase fluidized bed reactor 8; Influent weir 2 bottoms connect water inlet pipe 10; Sewage sewage and haydite in backflow one district that influent weir 2 evenly gets into first step inner loop three phase fluidized bed reactors 8 and pond are that bio-carrier mixes; Separation through flow deflector 4 gets into stage casing aeration lifting zone, and the effect of liquid level lower arc cowling panel 5 makes sewage and bio-carrier realize internal recycle through aeration lifting zone top when aeration promotes; Part of contaminated water and bio-carrier get into two districts that reflux, and air overflows from the lonely shape cowling panel 5 uncovered districts on top, recirculating zone.Simultaneously in two districts that reflux; The carrier seam that refluxes through the bottom, settling region flows into two districts that reflux after the equivalent sewage rectification that gets into influent weir 2; Sewage with friction, shear that sewage and bio-carrier mix in backflow one district that the microbial film plug-flow come off gets into second stage inner loop three phase fluidized bed reactor 9 and the inner loop three phase fluidized bed reactor pond, the second stage, Zhou Erfu is extremely.Because the sectional area of reactor drum aeration lifting zone in the stage casing makes solution-air prolong duration of contact less than carrying some tiny bubbles secretly in the sectional area of whole bed, simultaneously a large amount of liquid circulation meeting like this, thereby improved the transfer efficiency of oxygen.
Flow deflector 4, lonely shape cowling panel 5, water outlet cowling panel 6 vertically are fixedly connected with the front and back inwall of first step inner loop three phase fluidized bed reactor 8 and second stage inner loop three phase fluidized bed reactor 9 respectively; Lonely shape cowling panel 5 is positioned at flow deflector 4 tops with water outlet cowling panel 6; Aerating apparatus 7 is microporous pipe; Be many, crosswise fixed is in the bottom of first step inner loop three phase fluidized bed reactor 8 and second stage inner loop three phase fluidized bed reactor 9.
Every grade of interior living weight of inner loop three phase fluidized bed reactor can be controlled through filling the ceramsite carrier amount.The particle diameter of ceramsite carrier is 0.6～1mm, and loading level is not crossed party wall with carrier and is as the criterion.
Present embodiment only is used for the more detailed description to the utility model, therefore the utility model is not constituted qualification.
