Abstract
The invention relates to biological film filler and particularly relates to micro-aeration biological film filler, which belongs to the technical field of biological films. The biological film filler comprises a plurality of parallel hollow fiber films, wherein intake ends of the plurality of hollow fiber films are connected with an intake seal head jointly while exhaust ends of the plurality of hollow fiber films are connected with an exhaust seal head jointly. The intake seal head and the exhaust seal head are internally respectively provided with a sealed air cavity; the insides of the hollow fiber films are hollow and are communicated with the sealed air cavities of the intake seal head and the exhaust seal head. The biological film filler has the advantages of simple, compact and reasonable structure, small occupied area, capability of supplying air without bubbles, no secondary pollution such as sludge, big specific surface area, good decontamination effect, low cost and easiness for promotion.
Description
Technical field
The present invention relates to a kind of biofilm packing, a kind of micro-aeration biomembrane filler, belongs to technology of biological membrane field specifically.
Background technology
Filler is the microbial film place of perching of relying, and is biomembranous carrier, affects microbial growth, breeds, comes off and form and space structure, has the effect of holding back suspended matter concurrently simultaneously.Therefore, filler is the key component of BAF, and effect of BAF is had to direct impact, also has influence on structure formation and the cost of BAF simultaneously.The diaphragm type aerator that domestic current employing is arranged in Aerobic Pond is processed.Diaphragm type aerator utilizes roots blower to carry out oxygen supply, the filler such as PP, PE is generally all installed, as the carrier of microorganic adhesion in Aerobic Pond.The filler adopting all fails to take into full account the needs of biochemical reaction in structure aspects, simple in structure, specific surface area is little, and porosity is low, and compactedness is inadequate, poor stability, and microbial film tack is low etc., has limited the application of BAF in wastewater treatment in China.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of micro-aeration biomembrane filler is provided, have larger specific surface area, do not produce the secondary pollutions such as mud, reach good clean effect, cost is lower, easily promotes.
According to technical scheme provided by the invention, micro-aeration biomembrane filler comprises multiple hollow-fibre membranes parallel to each other, it is characterized in that: the inlet end of multiple hollow-fibre membranes connects inlet end end socket jointly, the outlet side of multiple hollow-fibre membranes connects outlet side end socket jointly; In inlet end end socket and outlet side end socket, be provided with sealed air-space, hollow-fibre membrane inner hollow is also communicated with the sealed air-space of inlet end end socket and outlet side end socket.
Further, hollow-fibre membrane comprises aerobic layer, facultative layer and anaerobic layer, and aerobic layer is positioned at innermost layer, and facultative layer is positioned at aerobic layer outer ring, and anaerobic layer is positioned at facultative layer outer ring.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and area occupied is little; Filler can still air feed, does not produce the secondary pollutions such as mud, has larger specific surface area, reaches good clean effect, and cost is lower, easily promotes.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-outlet side end socket, 2-hollow-fibre membrane, 3-inlet end end socket.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention mainly comprises multiple hollow-fibre membranes 2 parallel to each other, and the inlet end of multiple hollow-fibre membranes 2 connects inlet end end socket 3 jointly, and the outlet side of multiple hollow-fibre membranes 2 connects outlet side end socket 1 jointly.
Inlet end end socket 3 and outlet side end socket 1 adopt ABS engineering plastic materials to make, and in inlet end end socket 3 and outlet side end socket 1, are provided with sealed air-space, and hollow-fibre membrane 2 inner hollow are also communicated with the sealed air-space of inlet end end socket 3 and outlet side end socket 1.
Hollow-fibre membrane 2 comprises aerobic layer, facultative layer and anaerobic layer, and aerobic layer is positioned at innermost layer, and facultative layer is positioned at aerobic layer outer ring, and anaerobic layer is positioned at facultative layer outer ring.
When work, the sealed air-space by inlet end end socket 3, to the interior air feed of hollow-fibre membrane 2, is given vent to anger in hollow-fibre membrane 2 by the sealed air-space of outlet side end socket 1.In the sealed air-space of maintenance inlet end end socket 3 and outlet side end socket 1, have certain pressure, and this pressure is less than the bubbling pressure of hollow-fibre membrane.Oxygen in hollow-fibre membrane diffuses to the microbial film being attached to outside hollow-fibre membrane with molecular state, utilized degradation of contaminant by microorganism.
The present invention is simple in structure, compact, reasonable, has larger specific surface area, and area occupied is little; Filler can still air feed, does not produce the secondary pollutions such as mud, reaches good clean effect, and cost is lower, easily promotes.
