Abstract
The present invention relates to activated stuffing for treating water, and the activated stuffing is made of a bioactive substance added to a polymer material. The activated stuffing comprises an activated substance for promoting microorganisms to grow on the activated stuffing to form a biological film quickly; a practical surface area of the stuffing is enlarged to further enlarge the microorganism amount, and the bioactivity of the appearance specific surface area of the activated stuffing is increased; the addition of the activated substance can greatly reduce the production cost of the stuffing.
Description
Technical field
The present invention relates to water technology, particularly the used filler of biomembrance process treatment unit of water.
Background technology
Biomembrance process is meant that the microbial film to constitute attached to the microorganism on the carrier (filler) is a kind of water technology of main body purification of organic waste water in water treatment.As the filler of biofilm carrier, when early stage, use natural goodses such as slag, bamboo chip, batten; Developed subsequently with paper, glass reinforced plastic, plastics etc. is the honeycomb fashion or the closed assembly filler such as corrugated of material; Occurred again on this basis with plastics, pottery etc. is the dump packing such as ring-type multiaspect, hollow spheres, melon shape sphere of material; Developed with macromolecular materials such as plastics the eighties in 20th century is the hanging filler of material, as soft-filler, combined stuffing, semi soft packing, elastic solid filler etc.; Developing the nineties in 20th century with light plastic etc. is the floating stuffing of material.Above-mentioned filler just increase specific surface area, anti-clogging plug, development research has been carried out in aspects such as (as piling up, hang, suspending) to install and fix mode, but the material of filler is still inert, and microbial film is not promoted and activation.
Summary of the invention
The purpose of this invention is to provide a kind of active filler that is used for water treatment, contain active substance in this filler, have activity, can promote that microorganism grows in this active filler, form microbial film fast; Can increase the practical surface-area of filler, and then increase microbial biomass, that is improve the biological activity of the apparent specific surface area of active filler; The adding of active substance can reduce the production cost of filler.
The present invention realizes by following scheme:
A kind of active filler that is used for water treatment is a base material with the macromolecular material, is mixed and made into as reinforcing filler with active material, it is characterized in that: described active material is a biologically active substance, and its filling weight ratio is 0.5～60%.
Macromolecular material as base material among the present invention can be thermoplastic material (as polyethylene, polypropylene, polycarbonate, merchant's vinylchlorid, polyester, red shortness's rubber etc.) or thermosetting material (as Resins, epoxy, unsaturated polyester etc.).
Biologically active substance as reinforcing filler among the present invention can be that various flour, starch or any microorganism growth that can be provide the material of nutrition or the mixture of these materials.
When producing non-thread active filler, the median size of reinforcing filler should be greater than 100 microns, and minimum grain size should be less than 25 microns, and maximum particle diameter should and not satisfy the requirement of production unit greater than the wall thickness of active filler.
When producing thread active filler, the median size of reinforcing filler should not surpass 20% of silk footpath, and maximum particle diameter should not surpass 50% of silk footpath.
The present invention adopts the conventional technology of absorb fillers in macromolecular material to add reinforcing filler (biologically active substance), and the loading level of reinforcing filler is 0.5～60% (weight ratio).
Application target according to active filler, except that reinforcing filler, can also add one or more conventional additives, for example: adding lime carbonate, silicates, cement, glass fibre, asbestos wait and regulate density or intensity, add various vegetable and animals oils and make lubricant etc.
With existing filler contrast, active filler of the present invention has following advantage:
1, because biologically active substance is present in the surperficial and inner of filler, not only provide nutrition source for microorganism, also provide more physical attachment point for microorganism, because of the active filler possess hydrophilic property, its surperficial adsorption helps to produce fine and close micropopulation, be easier to microbial growth, promptly have fast, the active high advantage of biofilm speed.
2, because active substance is biodegradable, particularly the visible active substance that exists with the state of aggregation form by microorganism metabolism after, make active filler form a large amount of holes and concave point, become porous and shaggy structure, specific surface area sharply increases, thereby provides more apposition growth space for microorganism.
3, the adding of active substance reduces the cost of manufacture of filler greatly.
