Abstract
The utility model relates to a spiral net barrel combined biological rotating disc. The spiral net barrel combined biological rotating disc comprises a net barrel, wherein the two ends of the net barrel are respectively fixedly connected with a short shaft, a spiral piece is arranged on the outer wall of the net barrel, water inlet holes are distributed in the wall surface of the net barrel, and all the water inlet holes are communicated with the inner cavity of the net barrel. The spiral net barrel combined biological rotating disc has the advantages that a solid rotating shaft on the overall of the existing biological rotating disc is changed into a way that the two ends of the hollow net barrel are connected with the short shaft respectively, so that a biological membrane can be formed on the inner wall of the net barrel, quantity of biological membranes is increased, and the way that single discs on the existing biological rotating disc are combined is changed into the spiral pieces which are continuous on the whole; on one hand, membrane hanging quantity can be increased, so that the biological membranes on the spiral pieces successively get in and out water along the axial direction instead of getting in and out the water at the same time like discs, and the biological membranes can hardly fall off; on the other hand, a certain pushing force is applied to sewage to be treated, so that the sewage can flow along the axial direction of the net barrel, dissolved oxygen in the sewage can be increased, and oxygenation efficiency and treatment effect are improved.
Description
Technical field
The utility model relates to a kind of blodisc for biomembrance process sewage disposal, belongs to technical field of sewage.
Background technology
Blodisc technique is a kind of of biomembrance process dirty water living creature processing technique, this facture makes the microorganism of bacterium and mushroom, microfauna growth reproduction on blodisc filling carrier of protozoon one class, form membranaceous biological mud, it is microbial film, organic pollutant in microorganism panning sewage on microbial film, as nutrition, is purified sewage.Blodisc is the rotation that utilizes rotating disk, makes to be attached to the microorganism circulation back and forth in water and air on rotating disk, thereby has formed a continuous biological wastewater treatment process of covering oxygen, absorption, mass transfer, oxidative degradation.Organism in the oxygenizement water of decomposition that process microorganism in water passes through, and microorganism obtains airborne oxygen in air event, for oxygenizement.By continuous circulation, reach water purification object.
The blodisc using at present consists of one group of disc and rotating shaft conventionally, all disc strings are through in rotating shaft, rotating shaft drives all disc rotation, the region of disc approximately 40% is in water, disc surface growth has coenosis, microbial film on the disc rotating alternately contacts with useless water and air, and absorption and bio-oxidation organic pollutant, be purified sewage again and again.Between microbial film film and disc surface, because rotation produces shearing stress, along with the increase of biomembranous thickness, increase, acquire a certain degree and come off, then produce new microbial film.
At present, the disc form of domestic and international blodisc used is single, exists the shortcomings such as microbial film easily comes off, processing efficiency is low, energy consumption is higher.Chinese patent literature CN2345537 discloses a kind of < < high-efficient energy-saving net biological rotating disk sewage > >, is that to take a kind of corrugated body of special papery lamination be disc material.CN101177318 discloses a kind of < < unit type high-strength elastic packing smell-less biological turnplate > >, CN100391864C discloses a kind of < < stuffing composite rotating bio-disc sheet > >, porous spherical filler or elastic filler, the plate that pumps up water, disc framework, rotating shaft and guard, consist of, porous spherical filler is positioned at the guard of disc framework both sides.These technology are all at the material of disc and have texturally done improvement, and remain the array configuration of single disc, all discs pass in and out the water surface simultaneously, and processing efficiency has much room for improvement.
Summary of the invention
The deficiencies such as processing efficiency that the utility model exists for existing blodisc is lower, microbial film easily comes off, provide a kind of good purification, efficiency high, the spiral net cylinder combination blodisc of microbial film difficult drop-off.
Spiral net cylinder combination blodisc of the present utility model, adopts following technical proposals:
This rotating disk, comprises net cylinder, and the two ends of net cylinder are all fixedly connected with minor axis, on the outer wall of net cylinder, is provided with flight, on the wall of net cylinder, is distributed with prosopyle, and all prosopyles communicate with the inner chamber of net cylinder.
Flight can arrange bull, to increase total surface-area, increases and hangs modulus.
Above-mentioned rotating disk, has changed solid spindle whole on existing blodisc into the form that connects minor axis at hollow net cylinder two ends, makes the inwall of net cylinder also can form microbial film, has increased biofilm biomass.Simultaneously, changed the form of single disc combination on existing blodisc into whole continuous flight, can increase extension modulus on the one hand, make microbial film on flight continuous flow vertically, and do not resemble disc, do not pass in and out the water surface simultaneously, make microbial film difficult drop-off, on the other hand sewage is applied to certain thrust, make sewage increase the dissolved oxygen amount of sewage along the axial flow of net cylinder, improved oxygen-transfer efficiency and treatment effect.
The utility model is simple in structure, has increased biofilm biomass, and microbial film difficult drop-off makes the sewage can axial flow, increases the dissolved oxygen amount of sewage, has improved oxygen-transfer efficiency and treatment effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spiral net cylinder combination blodisc.
Wherein: 1, minor axis, 2, net cylinder, 3, flight, 4, prosopyle, 5, inner chamber.
Embodiment
As shown in Figure 1, spiral net cylinder combination blodisc of the present utility model, comprises net cylinder 2, the two ends of net cylinder 2 are all fixedly connected with minor axis 1, on the outer wall of net cylinder 2, be provided with flight 3, on the wall of net cylinder 2, be distributed with prosopyle 4, all prosopyles 4 communicate with the inner chamber 5 of net cylinder 2.Flight 3 can arrange bull, to increase total surface-area, increases and hangs modulus.
Above-mentioned rotating disk, the minor axis 1 by two ends is arranged on the tank of disposing of sewage, and the lower region of flight 3 is in sewage.In operational process, on the inwall of net cylinder 2 and the surface of flight 3, all produce microbial film, greatly increased biofilm biomass.Meanwhile, the flight 3 of rotation can make sewage along the axial flow of net cylinder 2, increases the dissolved oxygen amount of sewage, has improved oxygen-transfer efficiency and treatment effect.
Claims (1)
1. a spiral net cylinder combination blodisc, comprises net cylinder, it is characterized in that: the two ends of net cylinder are all fixedly connected with minor axis, on the outer wall of net cylinder, is provided with flight, on the wall of net cylinder, is distributed with prosopyle, and all prosopyles communicate with the inner chamber of net cylinder.
