The preparation method of the utility model filler comprises the following steps:
The manufacture of a spherical substrate, adopts polyurethane material to prepare filler spherical substrate by forming technology;
The formation of b expansion area covering of the fan, centrally axially excavates in spherical substrate surrounding with mould like many traces pears palladium, forms groove vertically and fan-shaped sheet component, or continues to form the groove at central shaft two ends and fan-shaped sheet component at central shaft to two ends excavation;
C fibrillation, extends to filling surface, forms densely covered, fluffy fiber cashmere.
Concrete fibrillation step is: at room temperature, being put into by filler adds in the overflow dyeing machine of water, the weight percent of filler and water is 1:5-12, open the speed operation 5-10 minute that overflow dyeing machine often turns with 2-3min/, sodium hydroxide 2-10 grams per liter is added in water, quadrol 1-5 grams per liter, after overflow dyeing machine continues to run 3-7 minute, with the ramp of 2 DEG C/min, constant temperature 20-60 minute after being warming up to 100 DEG C, is cooled to 60 DEG C of tapping, stops the running of overflow dyeing machine, washing, completes fibrillation.
The utility model filler adopts density at 0.98-1.08g/cm
3between elasticity reaming hydrophilic polyurethane foam Material cladding polyster fibre make.As: PEG/PET, PEG/ECDP/PET.
The utility model adopts complex spherical velvet style protruded packing structure, be made up of polyurethane material, polyurethane material comprises fiber reinforcement polyurethane matrix material, preparation technology is easy, filler has abundant pore structure, for microorganism provides breeding space, be a kind of fixed microorganism carrier of excellent performance, filler is formed by kernel, expansion area and suede district integrated combination.Suede district is formed by utilizing the coordinative role of alkali ammonia to carry out fibrillation process to urethane, and specific surface area is large, and filler unit and water body have good exchange interface.
The utility model filler matrix adopts spherical, under the stirring of aeration bubbles, filler there will be the state of high speed rotating, improve mass transfer effect, the passage that the groove of filler expansion area is formed can not form accumulation caking, high speed rotating can also make the dead film of filler immediately come off, and improves biological metabolism.
The groove that its covering of the fan expansion area of the utility model and spherical substrate are formed makes mass transfer Distance Shortened, substantially increase rate of mass transfer, and form double oxygen at spherical inner and even in spherical, be formed centrally anoxic condition, produce a large amount of facultative microbes, fine to the denitrification effect of nitric nitrogen and nitrite nitrogen.Have groove and suede district simultaneously, the unloading phase of making microorganism under collisionless Frotteurism rapid biofilm, this filler has a lot of groove and suede district, also very strong to the interception capacity of difficult degradation organic suspended matter.
The utility model helpfulness: the structure of the utility model filler uniqueness and technique thereof make its oxygenation capacity good, starts biofilm fast; Packing specific area is large, and the suede district of covering of the fan promotes microorganic adhesion, and form double oxygen at spherical inner and even in spherical, be formed centrally anoxic condition, on microbial film, microorganism is wide in variety, food chain length, has higher position reason ability; Filler is installed simple, and operational management is convenient; Filler is base shape with spherical, and under the stirring of aeration bubbles, this filler there will be the state of high speed rotating, and resistance is little, and demoulding upgrades easily; This filler with synthon urethane for basic material, good hydrophilic property.
