The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of decontamination effect improving remarkable, stable high efficient biological purifying device.
The technical solution of the utility model is as follows:
A kind of high efficient biological purifying device, but it comprises a framework that is formed by support fixation material framework, and the different heights place is provided with biological plate from level to level on the framework; Every layer of biological plate has certain thickness, and biological plate is formed by frame support and panel framework, is filled with immobilization microorganism particles in the biological plate, and the panel of biological plate is eyed structure, and width of mesh is less than the immobilization microorganism particles size.
The shape of described biological plate can be rectangle, ellipse, circle or trilateral etc.
Described immobilization microorganism particles is to utilize immobilization technology (comprising entrapping method, absorption method, crosslinking etc.) that microorganism species (comprising photosynthetic bacteria, yeast, nitrifier, vinelandii, lactobacillus, genus bacillus, actinomycetes, the lonely bacterium of leech etc.) is adhered to be fixed on particle or the block of making on the immobilization material; Described immobilization material can be alginates, carrageenin, agar, gelatin, silica gel, polyacrylamide (PACAM) gel for imbedded microbe, the embedded material (preferred sodium alginate and carrageenin) of polyvinyl alcohol lattice types such as (PVA), or the embedded material of microcapsule-types such as nylon, ethyl cellulose and nitrocellulose; Also can be for the absorption absorption carrier of microorganism such as gac, wood chip, sintered glass, porous ceramics, magnetite, diatomite, silica gel, Mierocrystalline cellulose, urethane foam, ion exchange resin etc.; Can also be for linking agent glutaraldehyde, polyethylene phthalein amine, Epicholorohydrin, pentanediol, bis-diazotized benzidine and the hexamethylene diisocyanate etc. of the crosslinked combination of microorganism.
Preferred version, described immobilization microorganism particles comprises the immobilization material with multi-pore structure, adhering in the multi-pore structure of described immobilization material fixedly has microorganism species.
But the frame support of described biological plate and panel adopt the support fixation material; But described support fixation material can be materials such as aluminium alloy, stainless steel, resin, plastics, timber.
The structure support body of biological plate in the utility model (being frame support and the peripheral panel of biological plate) but adopt the support fixation material, the peripheral panel of biological plate adopts eyed structure, filling immobilization microorganism particles in the biological plate; Will be from level to level biological plate be shelved on the framework, finally formed stable, biopurification device efficiently.
High efficient biological purifying device of the present utility model can directly drop in the polluted-water and use, and also can be positioned over to make it float on underwater certain position use on foam or the tire.
The beneficial effects of the utility model:
High efficient biological purifying device of the present utility model has following characteristics: (1) adopts immobilization technology that microflora is fixed up, and places special framework, and the different layerings in conjunction with framework form blocks of microbial film, and decontamination effect improving is remarkable.(2) effectively immobilization technology, physical layering are combined, guaranteed biomembranous formation and effectively lasting, decontamination effect improving is stable.(3) easy to use, flexible.
