Description
Technical field
The utility model relates to a kind of MBR membrane module with aerating apparatus.
Background technology
MBR membrane bioreactor is the sewage disposal technology of a kind of advanced person.The key part of MBR is hollow fiber film thread.The material of film silk is generally PVDF plastics or PVC plastics, film filament diameter between 1.0 ~ 2.8 millimeters, length 1 ~ 2 meter.Film silk surface is covered with tiny micropore, and middle part is hollow structure.In sewage disposal during actual use film silk, need the two ends of some film silks to export, be poured in two rectangular plastics putaminas with epoxy resin respectively, form sealed structure.Namely middle part is film silk, and two ends are plastics putaminas, putamina limit have the Graceful mouth of a river, forms a membrane module like this.The physical dimension of membrane module is generally long 1.2 meters; Wide 0.03 meter; High about 2 meters.Several membrane modules are installed on a support and just form a film group device.During operation, be put in sewage by MBR film group device, suction pump is connected with film silk endoporus by pipeline.Start suction pump, form vacuum in film silk inside.The sewage pressure of film silk outside is high, and film silk internal water is forced down, and under the effect of pressure difference, water, through the micropore on film surface, penetrates into hollow fiber film thread inside, flows to the putamina at two ends, flows to clean water basin by pipeline.Pollution substance is greater than fenestra aperture due to diameter, by stop to film silk surface external, achieves solid-liquid separation.In order to remove the pollution substances such as the mud that is adsorbed on film silk surface, aerating apparatus is provided with bottom film group device, by aeration effect, the gas-liquid two-phase turbulent flow of the instability upwards flowed is produced in film group device, film silk does not stop dynamic in current, air-flow and current flow axially through film silk surface alternately along film silk, under the washing away of biphase gas and liquid flow, constantly the pollution substance on film silk surface is taken away, thus keep film silk surface cleaning clean, reduce the mistake flow resistance on film silk surface, realize film silk continuously pumping water.
Find through long-time running, some fibre shape or particulate material is always had in sewage lagoon, after these materials enter film group device, often easily be suspended on film silk, under the promotion of current, constantly upwards wriggle, finally climb to the top of film silk, namely the root of putamina place film silk is gone up, one is agglomerated at this, along with foreign material are cumulative year in and year out, film silk is strutted to both sides, make top-film bundle enlarged volume, decrease current gap reserved between two membrane modules, the serious gap between two membrane modules of can causing is lost, plug current current path, affect the normal operation of film group device.
Similar membrane module, upper end is captation, and lower end is just used for fixing film silk, and the bottom of whole membrane module installs independent aerating apparatus, due to the denser that film silk is assembled, if aerating apparatus is in bottom, bad to the purging effect of film silk.Membrane module lower end size is the same with upper end, except fixing film silk, does not have other purposes, compares and take up room, and increases the manufacturing cost of film group device.
Summary of the invention
The purpose of this utility model is to provide a kind of MBR membrane module with aerating apparatus, this membrane module has good aeration effect, uniform aeration can effectively help film silk to shake, reach the effect of cleaning film silk surface mud, this membrane module is convenient to install and change simultaneously, can carry out processing combination according to needs of production.
The purpose of this utility model is achieved in that a kind of MBR membrane module with aerating apparatus, this membrane module is by upper header, lower aeration box, hollow fiber film thread and aeration tube composition, hollow fiber film thread upper end is connected with upper header, hollow fiber film thread lower end and lower aeration box top are tightly connected, aeration tube lower end is connected with lower aeration box top, aeration tube upper end and upper header lower surface are tightly connected, aeration tube is that vertical uniform interval is arranged, lower aeration box one end forms inlet mouth, and its other end is closed; On aeration tube, interval arranges solarization air cap from top to bottom, and solarization air cap lays respectively on the two side of aeration tube, blows respectively towards hollow fiber film thread.
Improve as one of the present utility model, be positioned at the solarization air cap on aeration tube top, its aperture is little, and the spacing between adjacent solarization air cap is large; Be positioned at the solarization air cap of aeration tube bottom, its aperture is large, and the spacing between adjacent solarization air cap is little.
As further improvement of the utility model, the caliber of aeration tube is three times of hollow fiber film thread external diameter.
When the utility model uses, sewage is full of at membrane module outside, header is communicated with film silk, the top that film silk lower end contacts with aeration box is sealed state, film silk inside produces negative pressure, water molecules enters the header of membrane module upper end by the surface micropore of film silk, aeration box is communicated with aeration tube, the top that aeration tube upper end contacts with header is sealed state, there is aeration aperture on aeration tube surface, aeration tube lower end hydraulic pressure is larger, therefore the perforate of solarization air cap is larger, aperture pitch is less, aeration tube upper end hydraulic pressure is little, the perforate of solarization air cap is little, aperture pitch is large, can ensure that aeration tube realizes uniform aeration from top to bottom thus, the overall aeration of film group device device is relatively uniform, the shake of film silk evenly, therefore the mud alluvial on film silk surface is slower, for extending film silk work-ing life and ensureing that the water outlet efficiency of film group device has significant effect.This membrane module has good aeration effect, and uniform aeration effectively can help the vibrations of film silk, reaches the effect of cleaning film silk surface mud, and this membrane module is convenient simultaneously installs and change, and can carry out processing combination according to needs of production.
