Description

A kind of recyclable external tubular ultrafiltration membrane module and its application process
Technical field
The invention discloses a kind of sewage filtration equipment, particularly a kind of recyclable external tubular ultrafiltration membrane module.
Background technology
Membrane bioreactor (MBR) is the New Wastewater Treatment Technology that Modern Membrane Technology is organically combined with biotechnology Art.It, by activated sludge and larger molecular organics matter effectively catching, substitutes second pond using membrane separation plant, has saved engineering and has accounted for Ground area.It is that country's garbage leachate uses most sides in processing at present with high treating effect, the low advantage of operating cost Method.
MBR is a kind of efficient wastewater processing technology, is the combination of biodegradable and UF membrane.First by aeration And filler by sludge by organic matter degradation, then by membrane module by sludge filtration.In sewage treatment project often by MBR with it is pre- Treatment, film advanced treatment system are combined, and form pretreatment-MBR- advanced treatment process.
Existing processing mode is mostly embedded ultrafiltration membrance filter, and built-in MBR is by bioreactor, membrane module, attraction Pump etc. is constituted, and membrane module is placed in inside bioreactor.Operation principle is:Mixed liquor is filtered by immersion type membrane component, is passed through Suction pump aspirates water outlet.
But, built-in MBR by factors such as sludgd depositions due to being influenceed, and membrane flux is generally 6~15L/ (m2h), interior Put formula MBR films to be immersed in sludge, film surface easily forms concentration polarization, easily cause film blocking;Need to carry out 1~3 time daily instead Rinse, need to be moved to the cleaning of medicine wash pool during Chemical cleaning, it is cumbersome.

Equidistantly one group of reinforcing ring is provided with the tubular ultra-filtration membrane.
Wherein, the filter assemblies are at least one.
Wherein, the tubular ultra-filtration membrane is at least 20.
Wherein, the filter pipe and tubular ultra-filtration membrane are coaxial.
Wherein, the tubular ultra-filtration membrane aperture is 0.1-0.3nm.
External MBR operation principles are:The water outlet of stoste pond is pumped to filter assemblies and filters by filtering, under pressure Penetration by liquid tubular ultra-filtration membrane water outlet in mixed liquor, filter liquor is discharged by delivery port, the pipeline that filtered fluid passes through the other end Stoste pond is recycled to, realizes that sludge retention time (SRT) departs from the relation of hydraulic detention time (HRT), improve biochemical system Activated sludge concentration (15~40g/L).
Reinforcing ring original creation enhancing membrane material and the strong key technology of base material adhesion, solution on colleague's tubular ultra-filtration membrane pipe Periosteum can only internal pressure work be unable to the international problem of backwash, cleaning frequency 2-3 month, film service life 8-10.
Beneficial effect:The invention discloses a kind of recyclable external tubular ultrafiltration membrane module, long service life, filtering Effect is strong, is not easily blocked.
