Description
Technical field
The present invention relates to a kind of composite fiber modular bio-filler and method for arranging thereof that is used for sewage disposal, belong to environment-friendly novel material field.
Background technology
Biomembrance process is one of important way of biological sewage treatment, and filler is the carrier that microbial film adheres to, and is the core of technology of biological membrane such as biological contact oxidation process, biological filter, is directly determining the treatment effect and the returns of investment of technology.Common in the market biologic packing material is that starting material are made with high molecular polymers such as polypropylene, polyethylene, polyvinyl chloride or polyester mainly, soft-filler, semi soft packing, elastic filler, combined stuffing etc. are arranged substantially, these materials have advantages such as intensity height, the material life-span is long, acid-proof alkaline is good, but also exist biofilm speed slow, shortcomings such as cost height.The special emphasis of filler exploitation is at the aspects such as specific surface area, filling-material structure and water distribution, gas distribution performance and microbial film renewal of filler.In actual applications, it is not enough to it is found that these fillers exist aspect the tightness of biofilm speed, biofilm amount and film and filler.
Polymeric amide has well hydrophilic and bioaffinity, but a little less than its resistance to impact shock, limited it greatly as the application of filler in the water treatment biochemistry pool, if can solve the strength problem of this kind fiber, it is applied in water treatment field, can improves the sewage disposal performance of biochemistry pool greatly.
Summary of the invention
The purpose of this invention is to provide a kind of composite fiber modular bio-filler and method for arranging thereof that is used for sewage disposal.
The described composite fiber modular bio-filler that is used for sewage disposal, i.e. fixedly tynex net 5 and trevira net 6 on stainless steel frame 1, in the middle of wherein tynex net 5 placed, both sides were trevira net 6, formed the composite fiber modular filler 8 of three-layer network shape.
The volume ratio of described trevira net 6 and tynex net 5 is 2: 1～2.5: 1.
The concrete steps of the method for arranging of the described composite fiber modular bio-filler that is used for sewage disposal are:
1) making of framework: the stainless steel square tube is cut, be welded into long-width ratio and be 1.5: 1～2: 1 stainless steel frame (1), framework interior opposite angle direction welding diagonal brace makes its Stability Analysis of Structures, and wherein the diagonal brace material is identical with framework;
2) making of tynex net: prepare 12 long be 1200mm, wide is the terylene cloth 3 of 15～20mm, with long 120D/36F tynex 4 usefulness sewing machine circles for 2000mm on terylene cloth 3;
3) making of trevira net: identical with the size and the production method of tynex net 5;
4) making of filler: tynex net 5 is placed middle, trevira net 6 places both sides, forms composite fiber web 2, and complex network is clamped with stainless steel frame 1, step up with clip, be made into long-width ratio and be 1.5: 1～2: 1 composite fiber modular filler 8;
5) installation of mould bases: the mould bases that angle steel 10 making of channel-section steel 7 or 50 * 50 * 4 are installed in biochemical treatment tank, channel-section steel 7 vertically is arranged in the biochemistry pool, spacing is 0.5～0.75m, and channel-section steel 7 ends are by being welded to connect angle steel, and angle steel 10 is connected with biochemistry pool pond body 9 by expansion bolt 11 again;
6) layout of filler: filler is connected with channel-section steel 7 by its stainless steel frame 1, and according to composite fiber modular filler 8 with become 55 °～75 ° at the bottom of the biochemistry pool, the method layout of adjacent column intersection.
Beneficial effect of the present invention:
The high-tenacity trevira has good tensile strength 5.6～8.0cN/dtex, impact strength is 3～4 times of tynex, thereby be widely used as biologic packing material, but, limited its ability of disposing of sewage to a great extent because its wetting ability and bioaffinity are relatively poor; Tynex has good bioaffinity and wetting ability, thereby its biofilm is fast, and can significantly improve microbe population in the biochemistry pool unit volume.The present invention forms the compound bio filler with tynex in conjunction with trevira; because the filler module has three-decker; the trevira in the outside is as the protective layer of middle tynex; its sewage disposal performance of the performance of tynex stability and high efficiency; so both more solve the weak problem of tynex impact resistance, solved the problem of trevira poor processing effect again.
