Embodiment
As shown in Figure 1 and Figure 2, a kind of tubular membrane element of the utility model comprises inner chamber 11 and supporting layer cylindraceous 12, and the outside surface of supporting layer 12 is coated with organic filter membranous layer 13.Wherein, organic filter membranous layer 13 can be the microfiltration membrane of surface apertures in 0.1 micron level, also can be the ultra-filtration membrane of surface apertures in 0.01 micron level, is formed by macromolecule material coating, and the material of film coating can be polyethersulfone, polysulfones, polyvinylidene difluoride (PVDF) etc.Supporting layer 12 can be permeable, allows water to enter inner chamber by organic filter membranous layer, and supporting layer 12 is made of the porous organic material of strengthening, such as adopting porous high-density polyester material.Because the existence of supporting layer, the tubular membrane element can have thicker diameter, can be designed as different internal diameters such as 4mm, 6mm, 8mm, 10mm or 12mm such as inner chamber 11, and the tubular membrane element can rely on the intensity of self to stand in the water voluntarily.The height of tubular membrane element can be designed as 200mm, 400mm, 600mm, 800mm, 1000mm, 1200mm and does not wait, to adapt to the different application occasion.
The end of inner chamber 11 is provided with water outlet 14, and water outlet 14 can be arranged on an end of inner chamber, the other end sealing, and blind end can be provided with supporting layer and filter membrane (as Fig. 3), and a seal cap 15 (as Fig. 4) also can be set.
As shown in Figure 5, above-mentioned tubular type membrane element can be applied in the integral type film biological reactor, and water-collecting tray 3 is fixed in the reaction tank 2, the upper end closed of tubular membrane element 1, and the water outlet of lower end is connected with water-collecting tray 3.Water-collecting tray 3 is casings of a relative closure, and as shown in Figure 7, its upper surface has hole 31, can be connected with the tubular membrane element, and its side is connected with suction pump by header.Tubular membrane element 1 relies on the intensity of self vertically to arrange, and is immersed in fully in the sewage of reaction tank.Consistent with traditional immersion hollow-fibre membrane filter type, under negative pressure state, filtering water sees through organic filter membranous layer and enters inner chamber, as shown in Figure 6, arrow is wherein represented the direction of current, is flowed to be drawn into header behind the water-collecting tray and to discharge, and active sludge then is intercepted in the biochemical reaction tank.But in the utility model, tubular membrane element 1 is immersed in the water fully, and the upper end does not have the water outlet termination, can not resemble the problem that produces sludge blockage the hollow-fibre membrane in the suction end of upper end.The below of membrane element can be provided with aeration tube 4, by the bottom aeration, just can keep the routine on film surface and clean.
The top of every membrane element seals with seal cap, enters sewage when preventing to aspirate, many membrane element component film assemblies, and the membrane element quantity that the membrane module of different model comprises does not wait to 1000 by 100.
