Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, described in be to explanation of the present utility model rather than restriction.
Referring to Fig. 1, combined type aeration MBBR, comprise that top one side offers the reactor body 10 of access opening 1, access opening 1 place of reactor body 10 is provided with cover plate, on the both sides of reactor body 10 sidewalls, be provided with the water inlet pipe 2 and the rising pipe 9 that are communicated with its inner chamber, and water inlet pipe 2 arranges higher than micro-pore aeration system 4 and rising pipe 9, in reactor body 10, be provided with circulation flow deflector 7, described circulation flow deflector 7 one sides are provided with perforated pipe aerating regulation system 3 near reactor body 10 inner bottom places, perforated pipe aerating regulation system 3 tops are provided with micro-pore aeration system 4, described perforated pipe aerating regulation system 3 is arranged at the inner side near water inlet pipe 2 of reactor body 10, reactor body 10 inner tops are provided with and prevent that floating stuffing 6 from floating on the back-purge system 5 on liquid level in reactor, and wherein, described back-purge system 5 is perforated pipe water distribution.The described inner side bottom near rising pipe 9 of reactor body 10 is provided with anti-deposition filter 8.Wherein, access opening is held concurrently as the venting hole of this reactor.
Wherein, perforated pipe aerating regulation system 3 major functions are to improve the fluidizing performance of floating stuffing 6, at the bottom of preventing filler deposition pond.
Perforated pipe aerating regulation system 3 design attitudes are lower, and bubble, in uphill process, due to mutual collision and the shearing action of floating stuffing 6 in water, makes air bubble more tiny, increase the utilising efficiency of oxygen.
Therefore, the more independent aerating system of composite aeration system has higher energy-saving effect.Same aeration rate (be identical energy consumption under), boring aeration can not meet the required dissolved oxygen concentration of system separately, and micro-pore aeration can not meet the power that floating stuffing reaches fluidized state separately.
Meanwhile, back-purge system 5 can be good at solving the problem of floating stuffing floating, and regularly back flushing can maintain floating stuffing and be uniformly distributed in reactor, keeps efficient processing power.
Back-purge system 5 is perforated pipe water distribution, and equipment is simple, requires low.After processing, water or former water can be used as backwashing water use, without special equipment and water source.
Principle of work of the present invention is:
It is by add the floating stuffing of some amount in reactor that combined type aeration moves biomembrane bioreactor principle of work, and its effect is biomass and the biological species improving in reactor, thereby improves the processing efficiency of reactor.Floating stuffing density is close to water, pass through aeration, be complete admixture with water, by regulating respective valves to adjust the aeration rate of boring aeration system and micro-pore aeration system, thereby realize floating stuffing, in reactor, present best fluidized state and the required dissolved oxygen amount of microorganism.Due to collision and the shearing action of floating stuffing in water, make air bubble more tiny, increased the utilization ratio of oxygen.In addition, inside and outside each floating stuffing (carrier), all there is different biological species, some anerobes of growth inside or double oxygen bacterium, outside is aerobic bacteria, each carrier is a microreactor like this, nitration reaction and anti-nitration reaction are existed simultaneously, thereby improved treatment effect, make sewage water outlet qualified discharge.
As shown in Figure 1, demonstration show that 3 pairs of fluidized states that increase inside reactor floating stuffing 6 of boring aeration system have obvious effect by experiment, and can realize part oxygenation function.Boring aeration system 3 designs in reactor internal recycle flow deflector 7 one sides and lower than the associated pipe of micro-pore aeration system 4 in addition, suitably adjust air demand ratio, can realize the circulation of floating stuffing 6 in whole reactor completely, the setting of the inner anti-deposition filter 8 of association reaction device again, has increased the space availability ratio of reactor greatly.The Main Function of micro-pore aeration system 4 is to provide the dissolved oxygen that biochemical system needs, and because its oxygen transfer efficiency is high, can greatly reduce energy consumption, and it designs in circulation flow deflector 7 one sides, further strengthens flowing of floating stuffing.Back-purge system 5 source qualities require low, can be water after former water or processing, and it designs in reactor head, and Main Function is to prevent that floating stuffing 6 from floating on the interior liquid level of reactor, makes floating stuffing 6 can not fully realize its function.
Tradition MBBR adopts independent perforated pipe aerating regulation system, there is the deficiencies such as energy consumption is high, oxygenation capacity is poor, oxygen utilization rate is low, in addition, the problems such as floating, sink to the bottom often appears in its main body formation---floating stuffing, can not give full play to its due function, cause on the one hand the waste of filler, cause on the other hand energy consumption to increase.The utility model is a kind of efficient sewage treatment installation that can energy efficient, and this equipment, on the basis of traditional MBBR, adopts two cover aerating system and a set of back-purge systems.Two cover aerating systems are respectively: perforated pipe aerating regulation and micro-pore aeration.The Main Function of perforated pipe aerating regulation is strengthened the fluidized state of floating stuffing, at the bottom of preventing being deposited on pond; The Main Function of micro-pore aeration is oxygenation, and its utilising efficiency to oxygen is high, avoids the problem of independent perforated pipe aerating regulation system dissolves hypoxgia.The floating stuffing of MBBR inside there will be regular " climbing wall " floating, designs overp0unch pipe water distribution back-purge system and can well solve this difficult problem in the utility model.The utility model is by increasing simple tubing system, at the bottom of having solved the inner floating stuffing sedimentation basin of traditional MBBR, the difficult problem such as " climbing wall " floating, dissolved oxygen deficiency, and the more perfect practical application of MBBR.
The utility model improves the fluidizing performance of inside reactor floating stuffing 6 and improves dissolved oxygen concentration in reactor, and what increase the inside reactor finite space makes full use of efficient processing and this reactor apparatus simple structure with sewage, successful.
The utility model is by the tubing system of simplicity of design, the difficult problems such as MBBR dissolved oxygen deficiency, floating stuffing poor fluidity, space reactor utilization ratio be low have successfully been overcome, give full play to the advantage of MBBR, improve effluent quality, and greatly reduce energy consumption, save running cost.
