The circumferential reinforcing columns are parallel to the circumference and are vertically welded with the 16 axial stress columns, one circumferential reinforcing column is welded on the axial stress column at an interval of 15mm, and the porosity between the circumferential reinforcing column and the axial stress column becomes a circumferential opening.

Description

A kind of porous cylindrical biologic packing material
Technical field
The present invention relates to the biologic packing material that industrial circulating water cultivating system water treatment is used.
Background technology
In industrial circulating water cultivating system water technology, the main high-efficient purification that adopts biomembrance process to realize breeding wastewater, reaches fishery water requirement.Filler is as the core component of biomembrane purification device, and its performance is very important to water treatment effect and operation control, and good carrier performance is the key of performance biomembrane purification device usefulness.Therefore, filler is generally paid attention in breeding wastewater is processed always.
The whole process that biologic packing material affects microbial growth, breeds and comes off as microorganism carrier, for microorganism provides the stable environment of perching and breeding; Filler is the place that in reactor, microbial film contacts with waste water, and can have enforceable turbulent fluctuation effect to current, and waste water can be distributed again.The material of filler, specific surface area size, filling surface roughness, distribute water and air performance, intensity, density and cost etc., directly affect the efficiency of wastewater treatment and the feasibility of operation.Organic polymer filler is one of biofilm carrier of at present tool development prospect, and common biologic packing material mainly be take polypropylene, polyethylene, polyvinyl chloride or polyester etc. and made as starting material in the market.
In industrial circulating water cultivating system water technology, most widely used inorganic polymer filler be take protruded packing as main, mainly comprises: zeolite, gac, biological ceramic particle, quartz sand etc. at present.The organic polymer fillers such as elastic solid filler are also in progressively popularization and application.Easily there is the problems such as biology silts up, microbial film upgrades difficulty, oxygen mass transfer coefficient is low in these biologic packing materials, causes processing efficiency sharply to decline in actual use.A kind of not only specific surface area of needs is large but also hole is also large, and is convenient to the new packing of modular combination.
Summary of the invention
The object of this invention is to provide that a kind of specific surface area is large and hole is also large, and be convenient to the porous cylindrical biologic packing material of modular combination, in order to overcome biologic packing material, easily there is in actual use the problems such as biology silts up, microbial film upgrades difficulty, oxygen mass transfer coefficient is low.
Technical scheme of the present invention consists of axially-loaded column, axial thin slice, circumference reinforcing prop, it is characterized in that described axially-loaded column is the solid cylinder of diameter 1mm, length 600mm, described axial thin slice is the flap of length 600mm, width 30mm, thickness 0.5mm, and described circumference reinforcing prop is the solid cylinder of diameter 1mm, length 219.8mm; Axially-loaded column is welded together with axially thin slice is parallel, with 16 axially-loaded columns, be vertically positioned on the circumference that diameter is 70mm, equispaced 22.5 degree between axially-loaded column, the axial thin slice being connected with axially-loaded column is towards axial line, be radial, axially between thin slice, form axial porosity; It is 70mm circumference that circumference reinforcing prop is parallel to aforesaid diameter, by circumference reinforcing prop together with 16 axially-loaded column vertical, in the total length of axially-loaded column at interval of 1 circumference reinforcing prop of 15mm welding, the hole forming between circumference reinforcing prop and axially-loaded column becomes circumferential openings, so just forms a kind of porous cylindrical biologic packing material.Described porous cylindrical biologic packing material is pressed 4 * 4 the mutual jam-packed of matrix-style, and carries out adhesion to being in contact with one another part, forms a filling block being comprised of 16 porous cylindrical biologic packing materials.Filling block is put into biological filter by axially-loaded column perpendicular to horizontal plane direction, and mutual jam-packed between filling block and piece, until fill filter tank.On filling block, be uniformly distributed pending waste water.
Outstanding feature of the present invention is that total surface area reaches 0.83976 square metre by optimizing filling-material structure, and specific surface area reaches 364m 2/ m 3, porosity reaches 82%, and its specific surface area is large, porosity is large, distribute water and air is functional, oxygen mass transfer coefficient is high, biofilm demoulding easy, be easy to modular combination.Cheap, easy for installation, long service life, especially when increasing packing specific area, also enlarged markedly porosity, significantly overcome biologic packing material the problems such as biology silts up, microbial film upgrades difficulty, oxygen mass transfer coefficient is low easily occur in actual use.

Embodiment
The present invention (referring to Fig. 1, Fig. 2) consists of axially-loaded column 1, axial thin slice 3, circumference reinforcing prop 2, described axially-loaded column 1 is to take the diameter 1mm that polypropylene processes as starting material, the solid cylinder of length 600mm, described axial thin slice 3 is to take length 600mm, the width 30mm that polypropylene processes as starting material, the flap of thickness 0.5mm, and described circumference reinforcing prop 2 is to take the diameter 1mm that polypropylene processes as starting material, the solid cylinder of length 219.8mm; Axially-loaded column is welded together with axially thin slice is parallel, with 16 axially-loaded columns, be vertically positioned on the circumference that diameter is 70mm, equispaced 22.5 degree between axially-loaded column, the axial thin slice being connected with axially-loaded column is towards axial line, be radial, axially between thin slice, form axial porosity 4; It is 70mm circumference that circumference reinforcing prop is parallel to aforesaid diameter, by circumference reinforcing prop together with 16 axially-loaded column vertical, in the total length of axially-loaded column at interval of 1 circumference reinforcing prop of 15mm welding, congruent melting connects 40 circumference reinforcing props, the hole forming between circumference reinforcing prop and axially-loaded column becomes circumferential openings 5, so just form total surface area and reach 0.83976 square metre, specific surface area reaches 364m 2/ m 3, porosity reaches a kind of porous cylindrical biologic packing material of 82%.
