A kind of multidimensional, heterogeneous modified support high-performance bio contact rotating disk
Technical field
The utility model relates to sewage disposal technology, specifically a kind of multidimensional, heterogeneous modified support high-performance bio contact rotating disk.
Background technology
Biological rotating disk is the technique that a kind of biomembrance process of early use is disposed of sewage, it is the artificial-strengthening of sewage irrigation and soil processing, this facture makes microfauna growth reproduction on biological rotating disk filling carrier of the microorganisms such as bacterium, actinomyces, fungi and protozoan one class, forms biomembrane. In sewage and biomembrane contact process, the organic pollution in the microorganism panning sewage on biomembrane, as nutrition, is purified sewage.
In current disclosed employing biochemical method device, biological rotating disk is made up of disc, haptoreaction groove, rotating shaft and drive unit. Disc adopts blade inserting to connect, and taking central tube as rotating shaft, the two ends of rotating shaft are installed on the bearing of semicircle haptoreaction groove. The 40%-50% of disc area is immersed in sewage, rotating shaft is higher than water surface 10-25cm, when work, drive unit drives disc one direction slowly to turn round, after rotating disk operation, biomembrane alternately contacts with the useless water and air in haptoreaction groove, when submergence, absorb the organic matter in waste water, when open, adsorb the oxygen in atmosphere. Air is brought in the rotation of disc into, and causes that in oxidation trough, waste water stirs, and dissolved oxygen in groove is uniformly distributed.
The disc shape of current domestic biological rotating disk is all dull and stereotyped disc or corrugated substantially, material mostly is plastics, fiberglass etc., also have to adopt to have the packing material of adsorptivity as the disc of biological rotating disk, or the mode of fixing certain sorbing material on rotating disk disc, as biofilm etc.
Current biomembrance process carrier has multiple, comprises immobilization carrier, suspending carrier, flexible carrier etc. Immobilization carrier, as honeycomb duct, is eliminated substantially. Elastic filler is a kind of soft fixed biologically carrier, is widely used, and fixed installation, but biofilm is conventionally more difficult. Combined stuffing is another kind of soft fixed biologically carrier, applies also very extensively, and surface area is larger, fixed installation, and biofilm is better. Various suspending carrier surface areas are large, easily biofilm, and biofacies is abundant, but mobility is large, easily plays heap with current.
The disc of domestic and international biological rotating disk used exists the shortcomings such as biomembrane easily comes off, treatment effeciency is low, energy consumption is higher at present.

Described fixed support rear and front end arranges respectively sewage import, clear water output, the sump between described sewage import and clear water output, and disc is in sump.
Disc cover is set directly over described disc, and disc cover is fixed on fixed support; Between adjacent phase disc entirety, be provided with sewage dividing plate, described sewage dividing plate is provided with sewage routeway.
Described turntable shaft is open circles oblique crank Z, and described turntable shaft two ends are fixed on fixed support by self-aligning bearing, and described turntable shaft comprises carbon steel, shafts body and is arranged on the anticorrosive coat of described carbon steel, shafts body.
Compared to prior art, the utlity model has following beneficial effect:
The utility model is arranged on enzymatic modification bio-carrier between disk plate for biological rotating disk by one group of special assembly, form bio-carrier rotating disk sewage treatment technique, give full play to the advantage of bio-carrier and bio-disc system, effectively avoid the shortcoming of disk plate for biological rotating disk, greatly improve treatment effeciency. Simultaneously can only one-directional rotation to current biological rotating disk, cause the inhomogeneous defect of overall sheet biofilm, by being installed, travel switch or programme-control realize the positive and negative rotation of biological rotating disk, accelerate the replacement speed of bacterial classification in biofilm speed and film.
High-performance bio rotating disk technique has following main feature compared with traditional biological rotating disk technique:
1) contaminant removal efficiency is high. Enzymatic living beings modified support is strongly hydrophilic carrier, can shorten the biofilm time, improves biofilm biomass. Biomass can reach 20-40g/L, is 5-10 times of traditional biological rotating disk disc, and therefore contaminant removal efficiency is very high.
2) rotating disk biofacies is abundanter, and disc biomembrane distributes more even. Timing conversion suitable owing to having realized, that rotate counterclockwise, has accelerated the biomembranous new and old replacement of disc, makes various aerobic bacterias, double oxygen bacterium, anaerobic bacteria symbiosis, and anti impulsion load ability is stronger.
