Abstract
A composite elastic filament material used as the biofiller in biomembrane method for treating sewage is prepared from the mother polypropylene particles containing the superfine tourmalinite particles and polypropylene particles through preparing filament, napping, and embossing.
Description
Technical field
The present invention relates to be used in the environmental protection biologic packing material of biomembrance process sewage disposal, refer to constitute the composite elastic silk material and the manufacturing technique method thereof of biologic packing material especially.
Background technology
Biomembrance process purifies water becomes one of important method of sewage disposal, and the silk material performance of using as the biologic packing material of biofilm carrier directly affects the effect of this method.In the biologic packing material of many rigid classes, soft class and medium-soft class formation form, tow shape stereo-elastic biologic packing material is because of hard and soft preferably combination property and characteristics simple and reasonable for structure, maintenance easy to operate are arranged, and is more apparent superior and practical.Its anti-waterpower and organic loading impact property are good, and the material life-span is long, and the adhesion conglomeration has preferable anti-dirt blocking ability and air water flow-disturbing performance.But the silk material smooth surface that this tow shape stereo-elastic biologic packing material uses, specific area is little, and biofilm is slower; Make raw material with simple material polypropylene, active low, these shortcomings have restricted its further developing in water treatment field to some extent.The process of this silk material is that polypropylene agglomerate according to a conventional method through extruder spray silk-coiling-stretching-traction-cut-out-oven dry, is made smooth silk material.
Summary of the invention
The present invention overcomes the shortcoming that above-mentioned biologic packing material elastic yarn material exists, and improves water and biomembranous activity, and a kind of be applied in the composite elastic silk material and the manufacturing technique method thereof that contain active material new in the water treatment of environmental protection, municipal administration, aquaculture are provided.
The present invention proposes a kind of with pp material with to contain the polypropylene agglomerate of tourmaline compound, through tow shape and curling shape elastic yarn material technological method for processing, make silk material with active function; Simultaneously this silk material is made biologic packing material, be applied to water treatment field such as environmental protection, municipal administration, aquaculture.Tourmaline is a kind of mineral crystal with environment-friendly function, its radiation-curable far infrared, release anion, generation bioelectricity, and contain trace element and several mineral materials.By the effect of infrared activated hydrone, the macromolecular mass of water is diminished, thereby promote the penetrability of water, dissolving power and energy make it easier turnover cell membrane, transport nutriment and promote metabolism.The comprehensive function of above all effects can improve biomembranous activity and purifying water effect in addition.
The process that production contains the composite elastic silk material of active material is, polypropylene agglomerate contains 20～35% tourmaline submicron-sized particulates, tourmaline submicron-sized particulate diameter 0.3～1 μ m, polypropylene particles and polypropylene agglomerate be by weight 10: 1～1.5 evenly mix after,, reel, stretch through extruder spray silk with the common process method; Increase plucking and double-sided embossing two procedures afterwards, that is, adopt serrated knife,, carry out the routine traction afterwards, cut off, dry then through the roller mill double-sided embossing with the monofilament plucking; Make elastomeric monofilaments, filament diameter 0.2-0.5mm.The monofilament overall appearance that adopts this explained hereafter is a linear, and its technological process is as follows: raw material mixing-spray silk-coiling-stretching-plucking-double-sided embossing-traction-cut-out-oven dry.
After the double-sided embossing operation, available machinery is expected crimping by stretching with silk, is placed under 155～160 ℃ the temperature to dry by the fire typing in 2～3 hours, and the silk material is spring-like, cuts off.The monofilament overall appearance that adopts this explained hereafter is that helical coil is curved, and its technological process is as follows: raw material mixing-spray silk-coiling-stretching-plucking-double-sided embossing-crimping by stretching-drying and shaping-cut-out.
The invention allows for the application of above-mentioned silk material in water treatment.The elastic yarn material that above-mentioned process is made is evenly distributed to be radiation-like and to intert and be bonded on the axial cord, makes the tow shape elastic biological filler with active function, adopts to hang or the mode of stacking is installed and is applied to water treatment field; Be particularly useful for dripping the utilization of formula filtering ponds.Adopt suspension or the mode of stacking that the biologic packing material with active function is installed in the trickling filter, because of silk material tool elasticity preferably, under the water droplet percussion, significantly vibration is continuously arranged, the part water droplet is rebounded upward, in trickling filter, play water distribution effect again, and the water droplet that falls more is tending towards homogenising, prolonged the time that in filler, stops, simultaneously owing to the friction between the water, impact can produce effective stimulation to this active material of tourmaline, external energy (comprising the electric charge increment) is provided, has increased the effect of air water exchange.
The present invention makes raw material because employing contains active function material tourmaline submicron-sized particulate, in production technology, increase plucking and double-sided embossing two procedures, make above-mentioned two kinds of monofilament radial section peripheries producing be the convex-concave polygon, monofilament surface is lousiness shape branch simultaneously, use such monofilament to make biologic packing material, not only strengthened its activity, and biofilm is rapid, specific area also increases substantially.Use this filler sewage to be carried out biomembrane and handle its NH as carrier
3 +-N, clearances such as COD all improve about 40% than conventional fillers.
