Abstract
The utility model discloses high-efficient energy-saving net-shaped biological rotating disk sewage treatment equipment which belongs to the technical field of sewage treatment of environmental engineering. As special paper overlapped corrugated bodies which have light weight, big specific surface area and good film hanging performance are adopted as disk sheet material, the utility model has the advantages of high treatment efficiency, energy saving, low cost, compact structure, small occupation area and convenient operation and maintenance. The equipment can meet the demands of the sewage treatment of general middle and small-sized slaughterhouses and other similar organic sewage treatment.
Description
The utility model relates to a kind of high-efficiency and energy-saving type netlike rbc sewage disposal device, belongs to field of environmental engineering sewage treatment.
Since over half a century, biological treatment is a main method of handling organic sewage always.Using more at present, bioremediation has activated sludge process and biomembrance process.Generally adopt activated sludge process at some large-scale wastewater treatment plants, quite ripe to the research of this technology, use very wide.But this method power consumption is high, and initial cost is big, generally is applied to the large-scale wastewater treatment plant in city.The application form of biomembrance process has: biological filter, blodisc and biological contact oxidation process generally are applied in middle or small sewage treatment.A kind of biomembrance process sewage disposal technology that blodisc is five, the sixties start in preceding Germany.China introduced and began the research of blodisc processing unit in 1972.Up to the present, blodisc has been widely applied in Industrial Wastewater Treatment such as chemical fibre, petrochemical industry and hospital sewage, the sanitary sewage disposal, has obtained effect preferably.Many innovative structures have appearred in the blodisc waste disposal plant, as patent CN86208402U.Blodisc sewage disposal device performance depends primarily on its disc material and structure thereof.The disc material of present most of blodiscs is: plastics tabula rasa, plastic corrugated sheet, steel plate, aluminium sheet, organic toughened glass, template bamboo clappers etc.Ubiquitous problem is that the specific surface area of disc is little, carrier surface forming biofilm property is poor, processing efficiency is low, disc is heavy, power consumption is high, cost is high or corrosion fatigue life is not short.
The purpose of this utility model is to adopt novel light weight, specific surface area is big, corrosion-resistant, physical strength the is high special papery lamination corrugated body disc material as blodisc, to improve the processing efficiency of blodisc equipment, reduce energy consumption, reduce cost, prolong its work-ing life.
High-efficiency and energy-saving type netlike rbc sewage disposal device described in the utility model comprises that with the material with light weight, the big characteristics of specific surface area be the blodisc of disc, preliminary sedimentation tank, header tank, second pond.Compare with general blodisc sewage disposal device, the utility model has the advantages that (1) novel disc has bigger voidage and specific surface area, voidage reaches 89.2%, thereby the processing efficiency of the more common blodisc of netlike rbc is much higher, the harder north flitch of its area organic loading is high by 50%, and the volume organic loading is that they are more than 3 times; (2) the novel discs tablet quality is light, and its density is 36.1kg/m
3, existing disc is light, and the rotating disk gross weight alleviates, and driving power reduces, existing rotating disk energy-conservation 8%; (3) novel disc is made of special papery, and cost is low, than domestic at present than popular rigid plastic sheet and glass epoxy cheap about 1/3.
Structure and technical process below in conjunction with description of drawings netlike rbc sewage disposal device.
The structure iron of accompanying drawing 1 high-efficiency and energy-saving type netlike rbc sewage disposal device
Accompanying drawing 2 netlike rbc organigrams
The disc structure synoptic diagram of accompanying drawing 3 netlike rbcs
As shown in Figure 1, high-efficiency and energy-saving type netlike rbc sewage disposal device is made up of preliminary sedimentation tank 1, feeding engine 2, header tank 3, header tank support 4, water inlet variable valve 6, flooding velocity meter 5, blodisc 7, second pond 8, mud backflow water pump 12, return flow meter 11, return valve 9, delivery pipe 10 and housing 13.The float water level sensor is housed in the header tank.Blodisc is a key equipment, and as shown in Figure 2, it is made up of motor 14, rotating shaft 15, water-in 16, disc 17, water outlet 18 and oxidation trough 19.The working part of blodisc is the multi-disc disc that is fixed in the rotating shaft, by the microbial film on the disc oxidation operation in the water is decomposed.Therefore, the performance of disc material is the key factor that is related to blodisc serviceability quality.The utility model has been to adopt a kind of novel papery lamination corrugated body material, and has adopted the disassembly and assembly structure shown in the accompanying drawing 3.Every disc is fixedly assembled by anchor clamps 22 by guide-localization groove 21 by six papery waved plates 20.The thick 50mm of disc is formed through boning after the special processing by six layers of corrugated paper.
Sewage enters preliminary sedimentation tank through behind the grid, and grid can be removed bigger internal organ, can remove oil, hair and internal organ foreign material in preliminary sedimentation tank; By feeding engine sewage is got to header tank then, flow automatically in the blodisc by waterhead, organism is adsorbed by microbial film in the sewage, after it is being carried the sewage film secretly and is leaving liquid level in the disc rotation process, sewage is along the downward drip of biofilm surface, airborne oxygen constantly is dissolved in the moisture film by effects such as absorption, mixing, diffusion, infiltrations.Simultaneously, microorganism absorbs dissolved oxygen from moisture film, again organism is carried out oxygenolysis, discharges the meta-bolites of bio-oxidation.Along with the blodisc continuous operation, microbial film constantly carries out the process that oxidation operation in the sewage decomposes.Cause the reduction of organic concentration in the oxidation trough sewage and the increase of dissolved oxygen content, so sewage is purified.Sewage enters second pond subsequently, and microbial film that some come off and suspended substance sedimentation are at second pond, and the clear water of second pond top is discharged through water outlet, thereby finishes the sewage disposal whole process.
Claims (4)
1, a kind of high-efficiency and energy-saving type netlike rbc sewage disposal device, form by preliminary sedimentation tank, header tank, blodisc, second pond, the blodisc that it is characterized in that carrying out a biological disposal upon and form into special papery corrugated body laminated material, its water-in communicates with header tank by under meter, and its water outlet communicates with second pond.
