Abstract
The utility model discloses a be applied to export block in MBBR technology blocks to cuboid structure and vertical placing. Aeration equipment is equipped with to the block below. It is equipped with the electric brush head to block the netlist face. The high -usage that back flush, operation management are simple, pack is packed, is convenient for to wash, need not to difficult the jam, improves the mobility of the carrier of l attached -growth biomembrane at reactor.
Description
Technical field
This utility model relates to a kind of MBBR, particularly relates to going out in a kind of MBBR of being applied to technique
Mouth block.
Background technology
MBBR (MovingBedBiofilinReactor, referred to as MBBR) is on the basis of fluid bed
The New Technology about Wastewater Treatment formed, has that disposal ability is high, energy consumption is low, need not backwash, the loss of flood peak is little, do not send out
The process characteristic of raw blocking.The proportion that key problem in technology is in reactor is prone to water freely under water, gentle agitation
The biofilm packing of motion, has higher specific surface area, and biomembrane can raised growth at filler surfaces externally and internally.Good
In oxygen reactor, by aeration effect, filler is promoted to move with current；In anoxia or anaerobic reactor, by machinery
Stirring makes filler move.For preventing the loss of filler in reactor, set a porous screen at reactor exit, biological
Film filler retains in the reactor by being contained in the fixed solid stainless steel mesh of reactor outlet.Use easily quilt of blocking for a long time
Filler blocks, and causes filter effect reduction of blocking, and needs often to clean.
The screen cloth of MBBR technology application at present is mainly the tubular block of horizontal positioned, and sieve aperture is easily blocked by filler, does not has
Flushing device, the most out of service need to carry out manual cleaning.
Summary of the invention
The purpose of this utility model is to provide and a kind of is not easily blocked, without the outlet being applied in MBBR technique of backwash
Block.
The purpose of this utility model is achieved through the following technical solutions:
The outlet block being applied in MBBR technique of the present utility model, blocks as rectangular structure and vertically places.
The technical scheme that thered is provided by above-mentioned this utility model is it can be seen that being applied to of providing of this utility model embodiment
Outlet block in MBBR technique, owing to block uses rectangular structure, is not easily blocked filler than cylindrical shape, and multiaspect is easy to
Rinse；Owing to vertically placing, the loss of flood peak is little, due to action of gravity, is not easily blocked, it is not necessary to backwash.
Accompanying drawing explanation
The structural representation of the outlet block being applied in MBBR technique that Fig. 1 provides for this utility model embodiment.
Fig. 2 is that the a-a of Fig. 1 is to structural representation.
Fig. 3 is that the b-b of Fig. 1 is to structural representation.

Detailed description of the invention
This utility model embodiment will be described in further detail below.
The outlet block being applied in MBBR technique of the present utility model, its preferably detailed description of the invention is:
Block for rectangular structure and is vertically placed.
Equipped with aerator below block.
Block surface is equipped with electric brush head.
The outlet block being applied in MBBR technique of the present utility model, primary structure has block, aerator, electronic
Brush, backwashing system etc..For preventing loss and the sieve pore blockade of biofilm packing in reactor, block shape is designed as
Cuboid, depending on its pore size is by the overall dimensions of biologic packing material, is disposed vertically, and lower section is provided with aerating system, uses
Boring aeration guard system, is not easily blocked.Online twister can be will be attached to blow off, it is to avoid cause excessive water
Head loss.Using water under high pressure that block carries out backwash, be provided with electric brush head simultaneously outside block, during operation, aeration adds punching
Brush.
Specific embodiment:
As shown in Figure 1, Figure 2, Figure 3 shows, the exit design one at Aerobic Pond exports block, and primary structure has block, aeration
Device, electric brush head, backwashing system etc..Block is designed as rectangular shape, outside its pore size is by biologic packing material
Depending on shape size, being disposed vertically, lower section is placed with aerator, uses boring aeration guard system, is not easily blocked.Block
Four sides, outside is equipped with electric brush head, and during operation, simultaneously aeration adds and washes away.During MBBR process operation, aerobic reaction
Reacting water completely in pond to filter through block, current, by entering sedimentation tank, are blocked to intercept biofilm packing and are stayed
In oxygen pond, improving the utilization rate of biofilm packing, the biofilm packing that part is easily blocked on block is by aerator and electricity
Dynamic brush head washing gets off, simultaneously below aerator can time biofilm packing be in suspension flow regime, improve filler
Utilization rate.
This utility model uses rectangular structure, is not easily blocked filler than cylindrical shape, and multiaspect is easy to rinse；Vertically place,
The loss of flood peak is little, due to action of gravity, is not easily blocked, it is not necessary to backwash；Operation management is simple, and lower section fills added with aeration
Putting, screen surface is equipped with electric brush head simultaneously, rinses simultaneously, reduce filler plugging machine meeting, while below aerator can
Make sinking filler retention suspended state, improve the utilization rate of filler, improve the biomembranous carrier of apposition growth in reactor
Flowing need not activity sludge reflux or circulation backwash.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model not office
Being limited to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model
Should be as the criterion with the protection domain of claims.
Claims (2)
1. the outlet block that a kind is applied in MBBR technique, it is characterised in that block as rectangular structure and vertically place, block surface is equipped with electric brush head.
The outlet block being applied in MBBR technique the most according to claim 1, it is characterised in that equipped with aerator below block.
