Description
Technical field
The utility model relates to water-treatment technology field, particularly relates to a kind of submerged hollow fibre membrane module in bioreactor.
Background technology
At present, the submerged membrane filtering technique has been widely used in water treatment field, and has become one of most popular sewage disposal technology.In immersion membrane filtration system, submerged hollow fibre membrane module in bioreactor is widely used in the filtration and leaching process for the treatment of fluid, is bringing into play more and more important effect.
The submerged hollow fibre membrane module in bioreactor that is applied in the immersion filtration system mainly contains several forms such as curtain type film assembly, " U " type curtain type film assembly, " seaweed type " assembly, column-type film components at present.
Wherein, curtain type film assembly adopts the both-end cast, and the film silk is monolithic or biplate is arranged, for the assembly of monolithic diaphragm, the film silk is too concentrated, and loading density is high, and diaphragm thickness is large, and aeration tube is installed in the assembly bottom when using, and assembly is easy cleaning not, and it is high that mud alluvial probability occurs; For the assembly of biplate diaphragm, although reduced to a certain extent film silk loading density and diaphragm thickness, owing to the passage between two diaphragms seals, so limited to the remission effect of mud alluvial.In addition, aeration tube is installed between two diaphragms of an assembly, and during aeration, air-flow directly washes away the hollow fiber film thread surface, has greatly increased the risk of the damaged fracture of film silk, the service life of having reduced assembly.
" U " type curtain type film assembly adopts single-ended cast, and the film silk is " U " type arranges, and general cast end is upper during use, and U-shaped end is wrapped on the aeration tube.For this type assembly, its membrane fiber length is both-end pourable component twice, and this means is having the film silk to occur in the damaged situation, and its membrane area reduction will be far longer than the both-end pourable component, thereby reduces the service life of assembly; Secondly, this type assembly " U " type end is without any protection, and very easily stressed becoming damages greatly " V " type to the film silk in making and use procedure, and then increases the damaged risk that ruptures of film silk.
" seaweed type " assembly adopts single-ended cast, and other end end socket is processed, and is fixing, but film silk sheet or column arrange, the cast end is lower during use, the film silk is " marine alga " shape and swims in the pending liquid." seaweed type " assembly since film silk stiff end below, stacking for preventing that film silk self from occuring, adopt the film silk of high rigidity to make to support own wt, and the film silk pliability of high rigidity is relatively poor more, the shake effect is bad in water, and then affects the cleaning performance of assembly; In addition, " marine alga " formula assembly must prevent the stacking or mutual winding of film silk for every assembly arranges framework when using, and the difficulty of both increased production, installing and constructing has increased again cost.
