Background technology
Blodisc technique is a kind of aerobic biological film method dirty water living creature processing technique, this facture makes the microorganism of mushroom, microfauna growth reproduction on blodisc filling carrier of protozoon one class, form membranaceous biological mud, it is microbial film, organic pollutant in microorganism panning sewage on microbial film, as nutrition, is purified sewage.Blodisc consists of one group of disc and rotating shaft conventionally, all discs are applied in rotating shaft, rotating shaft drives all disc rotation, the region of disc approximately 40% is in water, to utilize the rotation of rotating disk to make to be attached to the microorganism circulation back and forth in water body and air on disc, thereby formed a continuous biological wastewater treatment process of covering oxygen, absorption, mass transfer, oxidative degradation, organism in the oxygenizement water of decomposition that process microorganism in water passes through, and microorganism obtains airborne oxygen in air event, for oxygenizement.By continuous circulation, reach water purification object.
At present, domestic and international blodisc used exists the shortcomings such as microbial film easily comes off, processing efficiency is low, energy consumption is higher, and the rotation of disc needs external impetus, or electric power, or aeration, and running cost is high, and disc form is single simultaneously, and extension modulus is few, affects treatment effect.
The disclosed < < of Chinese patent literature CN101935134B biological rotating disk sewage treatment equipment > >, comprise aerobe rotating disk treatment unit, anaerobe rotating disk treatment unit and filtration unit, although by aerobe rotating disk treatment unit, anaerobe rotating disk treatment unit and filtration unit organic assembling, realize and remove organic pollutant, denitrogenation, precipitation, the multiple functions such as filtration, improved treatment effect, but the blodisc adopting is not still broken through the constraint of prior art.
Summary of the invention
The deficiency that the utility model exists for existing blodisc sewage disposal technology, provides a kind of good purification, efficiency high, and without power, running cost is low falls plug-flow biological sewage treatment device step by step.
The plug-flow biological sewage treatment device that falls step by step of the present utility model, adopts following technical proposals:
This device, comprise settling tank and one-level biological treatment tank at least, settling tank is connected by partition wall successively with biological treatment tanks at different levels, and the height of each pond body is reduced step by step by settling tank to last step biological treatment tank, be ladder-like arranged, biological treatment tank inner bottom part is curved; The bottom of settling tank is provided with fluid inlet and mud discharging mouth; On partition wall between settling tank and first step biological treatment tank, be provided with first step drop mouthful, on partition wall between first step biological treatment tank and second stage biological treatment tank, be provided with second stage drop mouthful, by that analogy, on the exterior wall of last step biological treatment tank, be provided with water port; In every one-level biological treatment tank, blodisc is all installed, blodisc comprises rotating shaft and disc, each disc compartment of terrain is run through and is fixed in rotating shaft, is provided with radially-arranged blade on disc, on each disc, is positioned on conplane blade and is connected with netting.
During said apparatus operation, sewage enters settling tank by fluid inlet, in settling tank, precipitate, top water body is fallen by first step drop mouthful, the blodisc promoting in first step biological treatment tank by blade rotates, the blodisc that the water body being fallen by second stage drop mouth promotes in the biological treatment tank of the second stage rotates, and forms a continuous multistage water-treatment biological process of covering oxygen, absorption, mass transfer, oxidative degradation.
The utility model all can generate microbial film on disc surface, blade surface and the netting of blodisc, increased extension modulus, greatly improved microbial biomass, the water body falling on the other hand impacts blade, drive blodisc rotates, without power, adopt multi-stage biological to process simultaneously, improved organic removal effect and processing efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model falls plug-flow biological sewage treatment device step by step.
Fig. 2 is the structural representation of blodisc in the utility model.
Wherein: 1, settling tank, 2, first step biological treatment tank, 3, second stage biological treatment tank, 4, fluid inlet, 5, mud discharging mouth, 6, first step drop mouthful, 7, blade, 8, blodisc, 9, second stage drop mouthful, 10, water port, 11, rotating shaft, 12, disc, 13, netting.
Embodiment
As shown in Figure 1, the plug-flow biological sewage treatment device that falls step by step of the present utility model, comprises settling tank 1 and one-level biological treatment tank at least, and settling tank and biological treatment tank all can adopt metal or plastic material manufacture.Settling tank 1 is connected by partition wall successively with biological treatment tanks at different levels, and the height of each pond body is reduced step by step by settling tank 1 to last step biological treatment tank, is ladder-like arranged, and biological treatment tank inner bottom part is curved, guarantees that biological treatment is without dead angle.In Fig. 1, there is two-stage biological treating pond, i.e. first step biological treatment tank 2 and second stage biological treatment tank 3, concrete quantity can be determined according to wastewater treatment capacity and treatment effect.The bottom of settling tank 1 is provided with fluid inlet 4 and mud discharging mouth 5.On partition wall between settling tank 1 and first step biological treatment tank 2, be provided with first step drop mouth 6, on partition wall between first step biological treatment tank 2 and second stage biological treatment tank 3, be provided with second stage drop mouth 9, by that analogy, on the exterior wall of last step biological treatment tank, be provided with water port 10.The height of first step drop mouth 6, second stage drop mouth 9 and water port 10 reduces successively.In every one-level biological treatment tank, blodisc 8 is all installed.
As shown in Figure 2, blodisc 8 is the same with existing structure, comprise rotating shaft 11 and disc 12, each disc 12 compartment of terrains are run through and are fixed in rotating shaft 11, in this device, on each disc 12, be also provided with radially-arranged blade 7, on each disc 12, be positioned on conplane blade and be connected with on 13, one discs of netting and have how many blades just to have how many nettings, that is to say that the quantity of netting is consistent with the quantity of disc blade.On disc 12 surfaces, blade 7 surfaces and netting 13, all can generate microbial film like this, greatly improve microbial biomass.The water body falling on the other hand impacts blade 7, drives blodisc 8 to rotate, without power.
During said apparatus operation, first sewage enter settling tank 1 by fluid inlet 4, in the interior precipitation of settling tank 1, bottom mud is regularly discharged by mud discharging mouth 5, top water body is fallen by first step drop mouth 6, fall on the blade 7 of the interior blodisc 8 of first step biological treatment tank 2, the blodisc 8 promoting in first step biological treatment tank 2 rotates.Equally, by the second stage drop mouthful blodisc that 9 water bodys that fall promote in second stage biological treatment tank 3, rotated.The above water of the blodisc in biological treatment tanks at different levels like this can make the contained oxygen diffusion dissolution of air in the moisture film on microbial film top layer, constantly supplements the required dissolved oxygen of its biological degradation.Microbial film alternately contacts with water and air, thereby has formed a continuous water-treatment biological process of covering oxygen, absorption, mass transfer, oxidative degradation.Employing multi-stage biological is processed, and has greatly improved organic removal effect and processing efficiency.
