Description
Technical field
The utility model is 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.
Background technology
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 owing to technology maturation, and equipment is reliable, is able to widespread use at large-scale wastewater treatment plant, but in the problem that has 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 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 big, processing efficiency is high, dismantle and overhaul easily that rotating bio-disc sheet can provide greater room to the application and the development of blodisc undoubtedly.
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 sewage disposal rotating bio-disc sheet of blodisc capacity utilization, minimizing blodisc floor space again.
Technical scheme: sewage disposal of the present utility model is made up of porous spherical filler or elastic filler, the plate that pumps up water, disc framework, rotating shaft, guard with rotating bio-disc sheet, the disc framework is leant on shape for circle, the both sides of disc framework are provided with guard, 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 porous spherical filler is positioned at the guard of disc framework both sides.
The particle diameter of porous spherical filler or elastic filler is Φ 60mm～Φ 120mm, and the filler material is a polyethylene, and Ball-type packing divides inside and outside double-deck spheroid, and the outside is a hollow fishing net shape spheroid, and inner is spheroid transition; Elastic filler is circular radiation filamentary texture, 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 rolling 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 the framework reticulated structure, can placing porous Ball-type packing or elastic filler in the net.Adopt porous spherical filler or elastic filler, 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, and 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, remedies the deficiency of traditional biological rotating disk.
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 rolling, frictional influence to promote biomembranous renewal.
