Abstract
The present invention is combined stuffing biological turntable sheet and relates to advanced domestic sewage and industry effluent treating technology in environment engineering science. The biological turntable sheet consists of porous spherical or elastic stuffing, water sprinkling board, frame, rotating shaft and netted cover. The porous spherical or elastic stuffing has 60-120 mm diameter and is made of polyethylene. The spherical stuffing includes two layers of balls, the outer is hollow netted ball and the inner is rotating ball. The elastic stuffing is in circular radial filament structure and is combined into string for suspension.
Description
Technical field
The present invention 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 invention is to provide a kind of removal efficient that can improve blodisc, can improve the stuffing composite rotating bio-disc sheet of blodisc capacity utilization, minimizing blodisc floor space again.
Technical scheme: stuffing composite rotating bio-disc sheet of the present invention is made up of porous spherical filler or elastic filler, the plate that pumps up water, disc framework, rotating shaft, guard, 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 present invention 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 present invention 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.

Specific embodiments
Below in conjunction with accompanying drawing patent of the present invention is further specified.
Stuffing composite rotating bio-disc sheet of the present invention is made up of porous spherical filler or elastic filler 1, the plate 2 that pumps up water, 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, be provided with the plate 2 that pumps up water on the excircle of disc framework 3, porous spherical filler 1 is positioned at the guard 5 of disc framework 3 both sides.The particle diameter of porous spherical filler or elastic filler 1 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 biological disc framework 3 of stuffing composite can adopt structures such as glass reinforced plastic and hard plastics among the present invention, and guard 5 adopts stainless steel or plastic wire.Can be arranged to the polylith assembly form according to the disc diameter size.Disc framework 3 intermediary gaps are 70mm～130mm, fill Φ 60mm～Φ 120mm porous spherical filler or elastic filler, filler is filled degree of compactness and is got 85%～90%, guaranteeing has certain voidage between filler, make filler that certain free gap be arranged in the dial rotation process, be convenient to microbial film and upgrade, guarantee higher removal.
