Technical field
Membrane bioreactor is the utility model is related to, more specifically to a kind of aerating system of membrane bioreactor.
Background technology
In recent years, application of the membrane technology in sewage treatment field is particularly the membrane bioreaction combined with bioreactor
Device (Membrane Bioreactor, abbreviation MBR) technique is answered to be received increasingly as a kind of new and effective sewage treatment process
Extensive concern.MBR is a kind of new water technology for mutually tying platform with biological processing unit by film separation unit, with membrane module
Substitution secondary settling tank keeps high activity sludge concentration to reduce sewage treatment facility occupation of land in the bioreactor, and by keeping low dirt
Mud load reduces sludge quantity.There is MBR techniques easy to operate, hydraulic detention time (HRT) to be separated with sludge age (SRT), sludge
The advantages that concentration is high, capacity of resisting impact load is strong, effluent quality is good.In membrane bioreactor, bioreactor is mainly completed
The degraded of dirty water pollutant；Film separation unit mainly completes separation of solid and liquid and some macromolecular compounds is played with retention work
With used film is generally ultrafiltration or microfiltration membranes.
In practical applications, since the membrane module of MBR in the process of running is vulnerable to pollution, flux depression, shadow are caused
The stable operation of membrane module is rung, fouling membrane is become the key issue of limitation MBR applications.Fouling membrane refers to suspended particulate, colloid

The intake interface 20 is connected with described into gas-bearing formation 8.Such design, optimizes the composition structure of housing 1, water outlet component and into
Gas component can be located away from housing 1, make the manufacturing of housing 1 simpler, while can be according to the requirement of client, binding modules
The sieve Slab element 22 of change designs the housing 1 of different length specification, and water outlet component and air inlet component are as both ends end cap
Structure is constant, is conducive to continue to use in follow-up products of different specifications, saves production cost, and production is more convenient, accurate, quick.
Further, in the present embodiment, the position that the housing 1 corresponds to the injecting glue layer 6 is equipped with hole for injecting glue 21, and described
Hole for injecting glue 21 is close to 3 side of the second sieve plate.Such design, on the one hand can convenient glue injection injecting glue layer 6 in, by film
Silk, aeration component 4, the first sieve plate 2 and the second sieve plate 3 and the sealing of housing 1 are fixed together, and improve the assembling effect of product
Rate, on the other hand since hole for injecting glue 21 is close to 3 side of the second sieve plate, for inversion state, (first sieves aerating system during injecting glue
Web plate 2 is downward), ensure that glue and the first sieve plate 2 are fully be bonded, while prevent glue from filling in the case of injecting glue layer 6
Infiltered by the second sieve plate 3 in water-yielding stratum 7.
Above disclosed is only the preferred embodiment of the utility model, certainly cannot be new to limit this practicality with this
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and are covered
Scope.
