Description
Technical field
The utility model is related to that a kind of aerobe pond is newly-built or processing system of upgrading, concretely relates to one
New MBBR microkinetics mixed biologic processing system is planted, belongs to technical field of sewage.
Background technology
Moving bed biological membrane process (MovingBedBiofilmReactor, MBBR), the core of MBBR techniques is to realize to hang
The abundant fluidisation of float carrier filler, to reach the purpose of intensive treatment pollutant, therefore, the technique is substantially to be related to biology to fill out
Material, Pool body design, aerating system, the organic unity for intercepting the equipment such as screen cloth.
Moving bed biological membrane process has fully drawn the advantage of bio-contact oxidation and biological fluidized bed, overcomes its mass transfer
The shortcomings of efficiency is low, treatment effeciency is poor, fluidisation power is high, with the general principle of biomembrance process, takes full advantage of activated sludge
The advantage of method, realizes that the activated sludge mode of biomembrane process is run.The fluidisation of biologic packing material relies primarily on exposure in aerobic zone
Gas system realizes, by appropriate aerating system ensure suspension biological carrier filling done in water body above and below, front and rear flowing,
Ensure that filler is sufficiently mixed with sewage, collided, contacted, efficiently accomplish pollutant, water, the contact of gas three-dimensional, exchange, suction
The process such as attached, so as to reach the purpose of intensive treatment pollutant.
With the continuous improvement of discharge standard, the engineer applied of moving bed biological membrane process is also more and more, but from reality
From the point of view of operation, prior art also there are problems that as follows：(1) inlet distribution inequality causes floating stuffing to be gathered around in processing system
Stifled, particularly water outlet, mass filler accumulation causes to occur in Practical Project to intercept screen cloth and the case such as collapsed；(2) filler stream
Changing need to invest high, energy consumption is big by extrinsic power.Such as impeller or air lift equipment, impeller is generally import equipment, and cost compares
Height, delivery cycle is long, once equipment, which goes wrong, may cause the paralysis of whole processing system；Air lift equipment need to increase air blast
Machine, high energy consumption, and it cannot be guaranteed that the active fluidization of filler, easily shows the problems such as congestion of water sieve net, deformation；(3) filler is added
Pond body use micro-pore aeration, it is time between overhauls(TBO) length, costly because the service life of microporous aeration disc is generally 5 years or so, and
Need that when periodic inspection, maintenance and replacing the problem of a large amount of floating stuffings are shifted will be faced；(4) when MBBR techniques are used to propose mark transformation
During engineering, because wastewater treatment structures have been built up, it is necessary to transformed according to former pool-type structure.Due to engineering one to be rebuilt
As built for early stage, generally use plug-flow type active sludge method, pond type length-width ratio it is big (>8:1), flow rate of water flow it is big (>10m/h).
Therefore, when floating stuffing is put into Chi Zhongshi, filler is pushed into pond latter end aggregation by quick current, not only influences wastewater treatment effect
Really, and cause pond body structural stress change, there is accident situation.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of new MBBR microkinetics mixed biologic processing system

It is preferred that, the pond body plane is rectangle, and the ratio of the long side of pond body and short side is 1~5: 1.
Advantageous effects of the present utility model are：
Sewage, even into aerobe pond pond body, carries floating stuffing and set out from influent side flow direction by water inlet system
Water intercepts the side of screen cloth, and sewage can be through screen cloth be intercepted, and floating stuffing is left in pond body；Pass through the non-of bottom aerated conduit
Be uniformly arranged and opening direction design arrangement, filler can return to influent side by air-flow and hydraulic action, will not intercept sieve
Accumulated at net, really solve the problem of filler blocks screen cloth, improve floating stuffing treatment effect and operation stability.
