Description
Technical field
The present invention relates to functional floating stuffing and manufacturing technology thereof that a kind of water treatment is used, be applicable to processing various waste water.
Background technology
The existing filler that is used for water treatment all is with polyethylene basically, polystyrene, and plastics such as polypropylene are made, as microorganism carrier in the biological treatment.Because the hydrophobicity of these plastics, therefore, microorganism is difficult in its surface attachment, and this class filler itself does not have other function except the carrier as microorganic adhesion usually.In order to improve and improve the functional of filler, " a kind of new type functional floating stuffing " application for a patent for invention (CN 03115913.3) proposes hydrophobic plastic filler and the material with special treatment function as zeolite (molecular sieve), gac, by functional material particle build-in is clamped between two plastic plates, organically combine and make functional floating stuffing, be difficult in its surface attachment to overcome the hydrophobic plastic packing microbial, the material of special treatment function not energy fluidizing and collide mutually and rub and wear and tear be lost the influence normal water treatment shortcoming, with the functional material particle is main bio-carrier, the microbial biomass of the unit's of making waste water greatly increases, and has strengthened the processing effect of microorganism greatly.But the complete processing complexity of this functional filler has increased the processing and manufacturing expense, and cost performance descends.And the size distribution of the functional water processing material carried secretly of institute's build-in can not be too close, must keep that good aeration is arranged between compound wing plate, cross the water-based energy, otherwise along with the metabolism of microorganism, can cause the conglomeration of microorganism mud to stop up, and is sunken at the bottom of the pond.The restriction of distribution density also causes the surface-area increasing amount of functional filler little, and the increasing amount of microbial biomass also is restricted.
Summary of the invention
In order to overcome the deficiency of existing capability filler, the present invention proposes a kind of powdery functional water processing material and wetting ability plastics of adopting makes together, area with functional water processing material is big, good waste water treatment effect, functional floating stuffing easy to make.
The functional water processing material that the present invention adopts be zeolite (molecular sieve) or/and gac or/and diatomite or/and haydite or/and active aluminum or/and other relevant microbe immobilizing material of manganese sand also can adopt photochemical catalytic material, as TiO
2And nanometer material for water treatment.And the functional water processing material clayed into power, fineness can be decided as required.These powder can be single uses when using, and also can be to use together after composite combined.Adopt the polarity plastics: as nylon, urethane, polyvinyl chloride, by surface heat in conjunction with or the surface adhesion agent is bonding etc. that method covers the polarity plastic sheet surface with Powdered functional water processing material becomes composition board, again composition board is cut into the wing plate of suspension functional filler, and is integral wing plate is fixedly connected by plastic fastening.Whole suspension functional filler be shaped as easily shape in welter.Because functional material and wetting ability plastics are often heavy than water, therefore can between some wing plates of floating stuffing body, sandwich an amount of porous plastics of refusing water, proportion with regulatory function floating stuffing and water, make the proportion of functional floating stuffing body approach one, functional like this floating stuffing can float on the surface when stopping the supple of gas or steam, the abundant fluidisation of energy is in water treating pond during aeration.The plate face of compound wing plate can not bump and rub mutually during fluidisation, forms the deficiency that powder runs off because of the phase mutual friction when effectively having overcome particle or block functional material fluidisation.
Advantage of the present invention is as follows:
1. at smooth smooth polarity plastics wing plate surface coverage functional water processing material, manufacture craft is simpler than the floating stuffing of build-in water entrainment processing capacity material, and it is coarse that the surface of wing plate has also been become, and has effectively increased the surface-area of floating stuffing.
2. floating stuffing is main bio-carrier with the functional material powder particle, these functional material surface irregularity, not only increased the surface-area of floating stuffing greatly, and high adsorption capacity, easier adhering on it of microorganism bred, form microbial film, improved the shortcoming that original plastics are difficult for attached microbial, biofilm development is more luxuriant.And, by the composite combined of various functional materials, can set up the micro-ecological environment that mixed bacterial is formed, make the water treatment detergent power can obtain very big improving.
3. because the functional water processing material is to be bonded in polarity plastics wing plate surface with very thin one deck powder particle, not to be clipped between the plastic plate with the particle embedding, so the space between the wing plate is big, have good aeration, cross the water-based energy, and under the situation that guarantees interval between the compound wing plate, wing plate can be set more, improve the surface-area of whole filler.
4. the porous plastics of refusing water is set in functional floating stuffing, can regulate the proportion of floating stuffing and water easily, make the proportion of functional floating stuffing body approach one, make functional floating stuffing when stopping the supple of gas or steam, float on the surface, the abundant fluidisation of energy is in water treating pond during aeration, easily script is difficult for fluidizing material fluidisation, make functional floating stuffing biological carrier and water, gas is fluidisation together, strengthened microorganism, organic substrate in the waste water, the impellent of mass transfer between the oxygen three in the air, the biography that has improved oxygen is moved the clearance of organic substrate in rate and the waste water;
5. the functional water processing material can adsorption and enrichment pollutants in waste water (ammonia nitrogen, organism etc.), for the microorganism digestion degraded that is grown on these material surfaces, effectively improved the clearance of pollutent, and the vital movement of microorganism has played the bio-regeneration effect to the functional water processing material; Photochemical catalytic material such as TiO2 and nanometer material for water treatment can produce a large amount of highly active free radicals under the irradiation of sunlight and UV-light, can degrade effectively and remove various organic pollutants.
6. in fluid mapper process, the aged microbial film easily comes off, so filler of the present invention need not often carry out back flushing as fixed bed, and has avoided running foul of each other and rubbing between the functional water processing material and has been worn and be lost.
