Description
Technical field
The present invention relates to UF membrane field, more specifically, it is to be related to a kind of doughnut membrane component from assembly and its dirt
Water treatment system.
Background technology
When water body suffers from organic contamination to become eutrophic water body, microorganism oxygen consumption decomposes the OUR making in water body
More than reoxygenation speed, so that the dissolved oxygen in water body is gradually consumed totally, cause water hypoxia, in anoxic water body,
Organic pollution is the suspended particulates such as sulfide by anaerobic digestion and hydrogen sulfide gas make the smelly formation of water body nigrescence black smelly
Water body.
Membrane Bio-reactor Technology is a kind of brand-new skill organically combining membrane separation technique with dirty water living creature processing technique
Art.In the built-in hollow fiber ultrafiltration membrane of membrane bioreactor, pollutant carries out biodegradable, simultaneously first in bioreactor
Mixed liquor in bioreactor in the presence of film pressure at both sides difference, water and pass through film less than the small molecule solute of membrane aperture,
Microorganism and macromolecular solute are rejected by, thus completing mud-water separation process.Film:Bioreactor is new and effective as one kind
Water technology, has that compact conformation, floor space are little, and the low effluent quality of excess sludge mud production rate is good, easy Automated condtrol
The advantages of, it is generally considered one of technology of sewage disposal most with prospects and water reuse.
Immersion MBR is that membrane module is placed in reactor, is provided with aerator below membrane module, and aeration one side is biology
Microorganism in reactor provides dissolved oxygen necessary to metabolism, on the other hand film surface is washed away, and mitigates film dirty
Dye.In integral type film biological reactor, aeration energy consumption accounts for 80% about that MBR system runs total energy consumption.Aerator is useless
Indispensable device in aquatic organism handling process, particularly in activated sludge process, aerator even more seems most important.Currently
Wide variety of aerator is broadly divided into blast aeration, mechanical aeration and joint aeration.
In membrane bioreactor (abbreviation MBR) practical application, evaluate aerating system quality not only aeration to be seen to film
The control effect of pollution, it is also contemplated that aeration energy consumption.In MBR aeration process, Air Bubble Size is mainly affected by aeration aperture,
Aeration aperture is bigger, and bubble diameter is bigger.Air Bubble Size affects the hydraulic shear that bubble produces, and produces weight to control membrane fouling
Affect；Aeration uniformity is one of factor of impact aeration effect, and when aeration uniformity is poor, the bubble of aerator release is not
Film can equably be washed away, film surface exists substantial amounts of " aeration blind area ", the film surface deposition in these regions has substantial amounts of pollutant,
Cause film local resistance to rise very fast, aggravate fouling membrane.
Content of the invention
The technical problem to be solved is to overcome above-mentioned the deficiencies in the prior art, provides a kind of hollow
Fiber film component and its sewage disposal system.
In inventive shell, cast hollow fiber hydrophobic membrane and external pressure doughnut hydrophilic film are or, wherein dredge doughnut
Moisture film is located at middle or center.
Hollow fiber hydrophobic membrane is milipore filter or microfiltration membranes；External pressure doughnut hydrophilic film milipore filter or microfiltration membranes.
Using the sewage disposal system of above-mentioned hollow fiber film assembly, by air blast, aerated conduit, hollow-fibre membrane group
Part, cesspool, water producing pipe, negative pressure pump and produce pond composition, air blast connect aerated conduit one end, the aerated conduit other end with
Hollow fiber hydrophobic membrane connection in hollow fiber membrane module, in hollow fiber film assembly, external pressure doughnut hydrophilic film and water producing pipe connect
Logical, water producing pipe passes through to arrange the pipeline of negative pressure pump and product pond UNICOM.
Compared with prior art, the invention has the beneficial effects as follows：
(1) the hydrophobic super/microfiltration membranes of doughnut primarily serve the purpose of fenestra aeration, and air particle diameter reaches micron order, and distribution is all
Even, effectively can provide air utilization ratio, Dissolved Oxygen in Water concentration is provided.
(2) air-flow that the hydrophobic super/microfiltration membranes of doughnut produce, can perpendicular to the hydrophilic super/microfiltration membranes surface of doughnut
Film surface is produced with strong purging and shake effect, is prevented effectively from generation deposition between membrane module upper and lower ends and film silk,
Improve the resistance tocrocking of membrane module.
(3) present invention is submerged hollow fibre membrane module in bioreactor, is applied to black and odorous water and administers, can be formed in river water body
Intensive uniform microbubble, provides Dissolved Oxygen in Water concentration, significantly improves water body environment.
