A membrane module for in-built filler, is provided with membrane component in described membrane module, is provided with packing space in described membrane module, is filled with granular filler in packing space.
The aperture of film itself is generally micron level or Nano grade, the granular filler of filling in packing space has following benefit: 1. when filtering, filler can be movable along with the flowing of feed liquid, the pollution layer on film surface is played to the effect of washing away, make pollution layer can not be deposited on the surface of film, alleviate the pollution on film surface; 2. granular filler is deposited in and itself forms filter course together, the pollutant in feed liquid is played to the effect tentatively retaining and filter, and the pollutant arriving film surface is greatly reduced, effectively reduces the pollutional load of film itself.
Preferred as technique scheme, described membrane module adopts end-filtration structure, membrane module is provided with feed entrance and pure water inlet.
End-filtration is simple to operate, is suitable on a small scale occasion, for solid content lower than 0.1% material usually adopt end-filtration.
Preferred as technique scheme, described membrane module adopts cross-flow filtration structure, membrane module is provided with charging aperture, pure water inlet and discharging opening.
Feed liquid is parallel to face flowing, and the shearing force produced when flowing through face with end-filtration unlike feed liquid takes away the particle that face is detained, thus makes pollution layer remain on a thinner level.
It is complicated that cross-flow filtration operates comparatively end-filtration, to solid content higher than 0.5% feed liquid usually adopt cross-flow filtration, along with the development of cross-flow filtration operating technology, have the trend replacing end-filtration in a lot of fields.
Preferred as technique scheme, described filler is porous particle.
Porous particle has suction-operated; can adsorb it before pollutant arrival film surface in feed liquid; thus protect film further and polluted less as far as possible, when processing the feed liquid of some kind, the decolorization of porous particle also can be supplemented with membrane filtration mutually.
Preferred as technique scheme, described filler is the mixture of one or more in carbon granule, ceramic particle, resin particle, sieve particle.
Preferred as technique scheme, described filler is natural stone particle.
Natural stone material comprises expanded perlite, porous vermiculite, natural zeolite etc.
Preferred as technique scheme, described membrane component is be fixed at least one diaphragm on circulation post, and diaphragm comprises the filtration side in outside and inner per-meate side, and per-meate side and circulation post are connected, and penetrating fluid flows out in the post that circulates.
Preferred as technique scheme, described packing space is the space between the filtration side of membrane component and membrane module shell, and packing space inside is filled with filler.
Preferred as technique scheme, described membrane component is the sub-assembly at least comprising one group of runner plate He be connected to the diaphragm on runner plate, described runner plate is provided with material liquid entrance and circulation fluid outlet, is also provided with permeate outlet.
Preferred as technique scheme, described membrane surface is provided with filter screen, between filter screen and membrane surface except filter screen hole imperforation, filter screen and membrane surface form packing space, and packing space inside is filled with filler.
The packing space airtight relative to feed liquid makes filler can not be taken away by feed liquid.
In sum, the utility model has following beneficial effect:
1. the membrane module of in-built filler described in the utility model effectively can alleviate the pollutional load on film surface, and when filtering to the pollution on film surface with cleaning effect;
2. the membrane module of in-built filler described in the utility model carries out adsorbing with protective film in advance to pollutant, and has the decolorization complementary mutually with membrane module.
