Abstract
The utility model relates to a rotating biologicaldisc plate used for biological sewage treatment, which belongs to biological sewage treatment technology in environmental engineering, in particular to an advanced technology for domestic sewage and partial industrial sewage in middle-size and small-size towns. The rotating biologicaldisc plate consists of ellipsoidal radiation silk type elastic fillers (1), a rotating biologicaldisc plate frame (2), a water raising plate (3), a rotating shaft (4), a concentric rigid support frame (5) and the like, wherein, the rotating shaft (4) is arranged at the circle center of the rotating biologicaldisc plate frame (2); the water raising plate (3) is arranged on the circumference of the rotating biologicaldisc plate frame (2); the ellipsoidal radiation silk type elastic fillers (1) are fixed by the concentric rigid support frame (5) arranged in the rotating biologicaldisc plate frame (2); the ellipsoidal radiation silk type elastic fillers (1) have the short radius between 20 mm and 50 mm, and the long radius of 50 mm; the ellipsoidal radiation silk type elastic fillers (1) are made of polythene which is combined into series suspended structure; and the concentric rigid support frame (5) can be made from rigid materials such as stainless steel, glass fibre reinforced plastics or rigid engineering plastics and the like.
Description
Technical field
The utility model is the dirty water living creature processing technique in the environmental engineering subject, is mainly used in middle-size and small-size sanitary sewage and Industrial Wastewater Treatment.
Background technology
Biological treatment is the main method of town domestic sewage and part industrial sewage second-stage treatment and advanced treatment at present, can be divided into activated sludge process and biomembrance process.Activated sludge process is because technology maturation, and equipment is reliable, is able to widespread use at large-scale wastewater treatment plant, but has problem such as fluctuation of service aspect the middle-size and small-size sewage disposal, and energy consumption is higher.The principal mode of biomembrance process has: biological filter, blodisc and biological contact oxidation process etc. are used for middle-size and small-size sewage disposal more.Blodisc originates from preceding Germany, because characteristics such as processing efficiency height, maintenance management are convenient, working cost is low, particularly uses in the small-sized sanitary sewage disposal of country such as Britain and Switzerland comparatively general in Europe.Traditional blodisc mostly adopts forms such as corrugation plastic plate, glass epoxy, and the disc shape is single, specific surface area is less, carrier surface forming biofilm property is relatively poor, processing efficiency is not high, work-ing life is shorter.
Therefore invent that a kind of specific surface area is big, processing efficiency is high, dismantle and overhaul rotating bio-disc sheet easily and the application of blodisc and development are promoted bigger space is provided.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of removal efficient that can improve blodisc, can improve the biological sewage treatment rotating bio-disc sheet of blodisc capacity utilization, minimizing blodisc floor space again.
Technical scheme: biological sewage treatment of the present utility model is made up of the thread elastic filler of elliposoidal radiation, the plate that pumps up water, disc framework, rotating shaft, concentric rigid stent etc. with rotating bio-disc sheet, the disc framework is leant on shape for circle, the inboard of disc framework is provided with concentric rigid stent, circle centre position at the disc framework is provided with rotating shaft, be provided with the plate that pumps up water on the excircle of disc framework, the thread elastic filler of elliposoidal radiation is fixed on the interior rigid stent of disc framework.
The short radius of the thread elastic filler of elliposoidal radiation is 20mm～50mm, and major radius is 50mm, and the filler material is a polyethylene, and the combination bunchiness hangs.Packing specific area is big, and the whole specific surface area of disc improves more than 15 times than traditional blodisc disc, and microbial film easily adheres to, and biomass is big, the processing efficiency height.Filler by certain free gap, promotes microbial film to upgrade by slip and frictional influence in disk body.
The utility model is a kind of technology that adopts new packing composite rotating bio-disc disk body to replace conventional one-piece formula rotating bio-disc sheet.This blodisc is a skeleton construction, the fixedly thread elastic filler of elliposoidal radiation on the rigid stent in the framework.Adopt the thread elastic filler of elliposoidal radiation, the disk body specific surface area increases more than 30 times than flat disc, even specific surface area utilization ratio 50% by filler, also increase more than 15 than flat disc, under same rotating disk volume, the area load and the hydraulic load of disk body can reduce greatly, area load and hydraulic load parameter designing according to rotating disk also are described, use novel combination type blodisc disk body can reduce the volume of rotating disk greatly, remedy deficiencies such as traditional biological rotating disk specific surface area is little, floor space is bigger.
Technique effect: the utlity model has following characteristics:
(1) this technology can significantly improve specific surface area, capacity utilization and the removal efficient of rotating disk;
(2) this technology can significantly reduce the floor space of rotating disk when guaranteeing certain rotating disk area load, hydraulic load and volumetric loading;
(3) this technology rotating disk filler combination mode is flexible, and convenient disassembly is easy to maintenance management;
(4) by adjusting the packing fraction of filler in the disk body, make filler in disk body, have certain slip, frictional influence to promote biomembranous renewal.
Description of drawings
Accompanying drawing is the front elevation of the utility model sewage disposal with rotating bio-disc sheet;
Have among the above figure: the thread elastic filler 1 of elliposoidal radiation; Disc framework 2; Plate 3 pumps up water; Rotating shaft 4 and concentric rigid stent 5.
Specific embodiments
Below in conjunction with accompanying drawing the utility model is further specified.Rotating bio-disc sheet of the present utility model is by the thread elastic filler 1 of elliposoidal radiation; Disc framework 2; Plate 3 pumps up water; Rotating shaft 4; Rigid stent 5 is formed with one heart, disc framework 2 is leant on shape for circle, the inboard of disc framework 2 is provided with concentric rigid stent 5, circle centre position at disc framework 2 is provided with rotating shaft 4, be provided with the plate 3 that pumps up water on the excircle of disc framework 2, the thread elastic filler 1 of elliposoidal radiation is fixed on the concentric rigid stent 5 of disc framework 2 inboards.The short radius of the thread elastic filler 1 of elliposoidal radiation is 20mm～50mm, and the filler material is a polyethylene, and the filler combination bunchiness hangs.Packing specific area is big, and the whole specific surface area of disc improves more than 15 times than traditional blodisc disc, and microbial film easily adheres to, and biomass is big, the processing efficiency height.Filler has certain free gap in disk body, by sliding and the renewal of frictional influence promotion microbial film.
