Description
Technical field
The present invention relates to the sewage disposal technology in the environmental engineering subject, is the modern technique that is applied to middle-size and small-size sanitary sewage and Industrial Wastewater Treatment, is specifically related to the technology of biological membrane field.
Background technology
Along with the quickening of urbanization process and the continuous growth of cities and towns industry, industrial sewage has become the important source of pollution of water surrounding, the increasingly sharpen deterioration of eutrophication and water surrounding in China lake, directly threatening the people's drinking water safety and the Sustainable development of urban economy.Biological treatment is the main method of sewage disposal at present, can be divided into activated sludge process and biomembrance process.Activated sludge process is due to technology maturation, and equipment is reliable, is able to widespread use at large-scale wastewater treatment plant, but aspect middle-size and small-size sewage disposal, has the problem of fluctuation of service, and energy consumption is higher.The principal mode of biomembrance process has: biological filter, blodisc and biological contact oxidation process etc., and multiplex in middle-size and small-size sewage disposal.Blodisc originates from front Germany, because processing efficiency is high, the characteristics such as maintenance management is convenient, working cost is low, in Europe particularly in the small-sized sanitary sewage disposal of the country such as Britain and Switzerland application comparatively general.Traditional blodisc mostly adopts the forms such as corrugation plastic plate, glass epoxy, and the disc shape is single, specific surface area is little, carrier surface forming biofilm property is poor, processing efficiency is low, work-ing life is short.Therefore invent that a kind of specific surface area is large, processing efficiency is high, dismantle and overhaul rotating bio-disc sheet easily can provide greater room to the application and development of blodisc undoubtedly.
Summary of the invention
The invention reside in and solve the technical problem that the disc shape is single, specific surface area is little, carrier surface forming biofilm property is poor, processing efficiency is low, work-ing life is short, a kind of removal efficiency that can improve blodisc is provided, and the sewage disposal that can improve again the blodisc capacity utilization, reduces the blodisc floor space is with pneumatic ceramic honey comb rotating bio-disc sheet.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: this rotating bio-disc sheet is comprised of porous honeycomb shape filler (1), air slot (2), disc framework (3), rotating shaft (4), guard (5), disc framework (3) is leant on shape for circle, the both sides of disc framework (3) are provided with guard (5), circle centre position at disc framework (3) is provided with rotating shaft (4), on the excircle of disc framework (3), be provided with air slot (2), porous honeycomb shape filler (1) is positioned at the guard (5) of disc framework (3) both sides.
The grain diameter of described porous honeycomb shape filler (1) is 60mm～120mm, and it is 85%-90% that filler is filled degree of compactness.
Described porous honeycomb shape filler (1) material is pottery, and the honeycombed filler divides inside and outside double-deck spheroid, and outside is hollow fishing net shaped honeycomb, and inner is honeycomb transition, and the combination bunchiness hangs.
Described disc framework (3) adopts the structures such as glass reinforced plastic and hard plastics, and the gap in the middle of disc framework (3) is 70mm-130mm.
Described guard (5) adopts stainless steel or plastic wire.
Useful technique effect of the present invention is: this blodisc is the framework reticulated structure, can placing porous honeycombed filler or elastic filler in net.Adopt porous honeycomb shape filler or elastic filler, the disk body specific surface area increases more than 30 times than flat disc, even the specific surface area utilization ratio 50% by filler, also than flat disc, increase more than 15 times, under same rotating disk volume, 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 greatly reduce the volume of rotating disk, make up the deficiency of traditional biological rotating disk, following characteristics more arranged:
(1) this technology can significantly improve specific surface area, capacity utilization and the removal efficiency of rotating disk;
(2) this technology, when guaranteeing certain rotating disk area load, hydraulic load and volumetric loading, can significantly reduce the floor space of rotating disk;
(3) this technology rotating disk filler combination mode is flexible, and convenient disassembly, be easy to maintenance management;
(4) by adjusting the packing fraction of filler in disk body, make filler in disk body, have certain rolling, frictional influence to promote biomembranous renewal.

Embodiment
For making those of ordinary skill in the art more be expressly understood objects and advantages of the present invention, the present invention is further elaborated below in conjunction with drawings and Examples.
With reference to shown in Figure 1, pneumatic ceramic honey comb rotating bio-disc sheet disclosed in this invention comprises that porous honeycomb shape filler (1), air slot (2), disc framework (3), rotating shaft (4), guard (5) form, disc framework (3) is leant on shape for circle, the both sides of disc framework (3) are provided with guard (5), circle centre position at disc framework (3) is provided with rotating shaft (4), on the excircle of disc framework (3), be provided with air slot (2), porous honeycomb shape filler (1) is positioned at the guard (5) of disc framework (3) both sides.The grain diameter of porous honeycomb shape filler (1) is 60mm～120mm, and material is pottery, honeycombed filler (1) minute inside and outside double-deck spheroid, and outside is hollow fishing net shaped honeycomb, inside hangs for honeycomb transition, combination bunchiness.Packing specific area is large, and the whole specific surface area of disc improves more than skilful times than traditional disk plate for biological rotating disk, and microbial film easily adheres to, and biomass is large, and processing efficiency is high.Filler by certain free gap, promotes microbial film to upgrade by rolling and frictional influence in disk body.
