The membrane/carbon composite filter element is used for purifying a water body, and comprises a barrel and an upper seal head and a lower seal head which are welded at the upper and lower ends of the barrel and are used for sealing the barrel, wherein a blocking sheet with micropores uniformly formed in the surface is arranged on the inner wall of the middle part of the barrel; activated carbon is filled in the barrel between the blocking sheet and the upper seal head; a hollow fiber ultra-filtration membrane is arranged in the barrel between the blocking sheet and the lower seal head; a water distributor with small holes uniformly formed in the surface is arranged on the inner wall of the barrel between the upper seal head and the activated carbon. The membrane/carbon composite filter element disclosed by the utility model has the beneficial effects that two filter materials are assembled together in an effective space, and are subjected to the filtration effects of activated carbon and the hollow fiber ultra-filtration membrane in sequence so as to obtain good filtration effects; the filter element is small in overall structure volume, convenient in assembly and disassembly, convenient in use, and safe and environmentally friendly.
Description
Technical field
The utility model relates to a kind of film/carbon composite filter element.
Background technology
Activated charcoal filter is the process that the pollutent of suspended state in water is held back.Gac is all effective to most organism in water, comprise that microorganism is difficult to the organism of degraded, granulated carbon can be regenerated and be reused, the organism being adsorbed is burnt in regenerative process, do not produce mud, therefore, charcoal absorption is widely used in municipal sewage treatment, tap water and Industrial Wastewater Treatment.
Ultrafiltration membrance filter can not see through macromole solute, stays one side of film, thereby makes macromolecular substance obtain the purifying of part.Ultrafiltration principle is also a kind of membrane sepn Principle of Process, ultrafiltration utilizes a kind of pressure active membrane, colloid, particle and the relatively high material of molecular weight in the lower trap water of extraneous impellent (pressure) effect, and water and little particles of solute are through the sepn process of film.The objectionable impuritiess such as the bacterium in the thorough filtering water of hollow fiber ultrafiltration membrane energy, iron rust, colloid, retain in water the useful trace element of human body and mineral substance.
In water treatment, commonly use activated carbon filtration or hollow fiber ultrafiltration membrane and filter, or after activated carbon filtration, adopting again hollow fiber ultrafiltration membrane to filter, device is complicated, operate lengthy and tedious, poor filtration effect.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of film/carbon composite filter element.
The utility model solves the technical scheme that its technical problem adopts: a kind of film/carbon composite filter element, for purifying water body, comprise cylindrical shell and the upper cover for sealed cylinder, the lower cover that are welded in cylindrical shell upper and lower ends, the inwall at cylindrical shell middle part is provided with the barrier flaps of surperficial uniform micropore, in cylindrical shell between barrier flaps and upper cover, be filled with gac, in cylindrical shell between barrier flaps and lower cover, hollow fiber ultrafiltration membrane is installed, the water distributor of surperficial uniform aperture is installed on the cylinder inboard wall between upper cover and gac.
Further, the raw material of gac is coconut husk, and specific surface area is 1500m
2/ g, granularity is 20～100 orders.
Further, the diameter of micropore is for being less than 20 orders, and the diameter of aperture is 0.5mm.
Further, hollow fiber ultrafiltration membrane is polysulfone hollow fibre ultra-filtration membrane, and external diameter is 0.5 ± 0.02mm, hollow fiber ultrafiltration membrane by resin-cast in cylinder chamber.
The beneficial effects of the utility model are: in the useful space, two kinds of filtering materials are assembled together, successively pass through the filtration of gac and hollow fiber ultrafiltration membrane, good filtration effect; Filter core one-piece construction volume is little, and easy accessibility is easy to use, safety and environmental protection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. cylindrical shell, 2. upper cover, 3. lower cover, 4. barrier flaps, 5. gac, 6. hollow fiber ultrafiltration membrane, 7. water distributor.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of film/carbon composite filter element as shown in Figure 1, for purifying water body, comprise cylindrical shell 1 and the upper cover 2 for sealed cylinder 1, the lower cover 3 that are welded in cylindrical shell 1 upper and lower ends, the inwall at cylindrical shell 1 middle part is provided with the barrier flaps 4 of surperficial uniform micropore, in cylindrical shell 1 between barrier flaps 4 and upper cover 2, be filled with gac 5, in cylindrical shell 1 between barrier flaps 4 and lower cover 3, hollow fiber ultrafiltration membrane 6 is installed, the water distributor 7 of surperficial uniform aperture is installed on cylindrical shell 1 inwall between upper cover 2 and gac 5.
The raw material of gac 5 is coconut husk, and it is raw material that cocoanut active charcoal be take the high-quality Exocarpium cocois (Cocos nucifera L) on the ground such as Hainan, South East Asia, and raw material is refinement treatment after screening, water vapour carbonization, and then is made through series of processes such as removal of impurities, activation screenings.Its pore texture is flourishing, is 5 times of common gac, and specific surface area is 1500m
2/ g, granularity is 20～100 orders, and particularly pore structure is unusual, and pore diameter is greater than 0.45nm and is less than 2nm micropore and accounts for sum more than 90%.There is flourishing pore texture, adsorptive power is high, intensity is large, stable chemical performance, durable in use, use safety.Gac 5 can be effectively except compositions such as the chlorine in anhydrating and TTHMs and money soluble in water and agricultural chemicals.
Hollow fiber ultrafiltration membrane 6 is polysulfone hollow fibre ultra-filtration membrane, and external diameter is 0.5 ± 0.02mm.Hollow fiber ultrafiltration membrane 6 bendings are inverted U, the mouth of pipe place of its lower end passes through resin-cast, fixing seal is in cylinder chamber, and the hollow fiber ultrafiltration membrane 6 of resin layer top plays good centrifugation, by contaminant filters such as the red embroidery in water and dregs, aluminium, bacteriums.
The water distributor 7 of gac 5 tops plays the effect that disperses water body, and the diameter of the aperture that its surface is offered is 0.5mm, makes to be evenly distributed through the water body of upper cover 2.The barrier flaps 4 of gac 5 belows plays the effect that stops gac 5, and the diameter of the micropore that its surface is offered, for being less than 20 orders, prevents that gac 5 from covering the surface of hollow fiber ultrafiltration membrane 6 and affecting its centrifugation.Meanwhile, barrier flaps 4 is divided into upper and lower two chambers by cylindrical shell 1, has guaranteed that water body must first pass through the filtration of gac 5, then by hollow fiber ultrafiltration membrane 6.
