Description
Technical field
The present invention relates to a kind of aerobic sewage disposal device of biomembrance process, relate in particular to a kind of blodisc formula aerobic treatment equipment with water circle device.
Background technology
Blodisc is a kind of biomembrance process aerobe treatment facility, and this technology was started at former federal republic of germany the sixties.Its chief component has disc, catalytic oxidation groove, live spindle and drive unit.Its turntable is the core processing structures of biological disk treatment system.Its principle of work: disk floods slow circumvolve under the state of about 40%-50% in water, after for some time rotates, on rotating disk, be about to adhere to the microbial film that one deck is growing a large amount of microorganisms, the kind of microorganism is stable gradually, the metabolic function of microorganism is also brought into play step by step and is reached stable degree, and the organic pollutant in sewage is microbial film institute absorption degradation.Dial rotation is left sewage and is contacted with air, set water layer on microbial film absorbs oxygen from air, and the oxygen in set water layer is oversaturated, and is delivered in microbial film and sewage, make the dissolved oxygen content of sewage in groove reach certain concentration, even may reach capacity.
Between the microbial film adhering to and sewage and air, carrying out exchange of substance on rotating disk, organic matter removal (showing as BOD, COD) and O
2also carrying out other materials, as CO outward,
2, NH
3deng transmission, referring to Fig. 1-1 and Fig. 1-2.Microbial film progressive additive, portion forms anaerobic layer within it, and starts aging.Aging microbial film peels off under the effect of the shearing force producing between sewage current and card, and the broken microbial film peeling off is trapped in secondary sedimentation basins, the mud that biofilm detachment forms, and density is higher, be easy to precipitation.
Blodisc is often used to two stage biological and processes, and its basic procedure is: primary sedimentation basin, blodisc and secondary sedimentation basins.Fig. 2 is shown in its technical process.First sewage enter primary sedimentation basin, removes larger floating and material that can sedimentation.Primary sedimentation basin water outlet is processed through multi-stage biological rotating disk, can from sewage, remove that dissolve and organism suspension.Meanwhile, the microbial film on rotating disk is thickening gradually, and superfluous microbial film peels off owing to producing the effect of shearing between sewage current and card.The sewage of processing through blodisc and peel off lower microbial film and enter secondary sedimentation basins and precipitate, next stage processing unit is discharged or enters in precipitation water outlet.
But traditional blodisc treatment technology, primary sedimentation pond capacity of resisting impact load is poor, and secondary sedimentation basins sludge bucket volume is larger, causes processing outlet effect poor.
Summary of the invention
The present invention is directed to the drawback of prior art, a kind of blodisc formula aerobic treatment equipment with water circle device is provided, primary sedimentation pond, blodisc and secondary sedimentation basins are carried out to integrated design, and be provided with water wheels, water wheels involved in the present invention refer to: the Water draw-off pump that is positioned at blodisc end.Along with this Water draw-off pump of rotation of blodisc rotates thereupon, constantly in contact-oxidation pool, draw part water, and constantly this part water is back in primary sedimentation pond, the present invention has broken the technical process of traditional blodisc, having realized the water outlet of blodisc process section can not increase under the prerequisite of any extra power, be back in primary sedimentation pond, complete the biological recirculation between catalytic oxidation groove and preliminary sedimentation tank, thereby make primary sedimentation pond upper strata keep the state of oxidation, increase the capacity of resisting impact load of whole treatment system, improve processing efficiency.
In order to solve the problems of the technologies described above, a kind of blodisc formula aerobic treatment equipment with water circle device of the present invention, comprise primary sedimentation pond and secondary sedimentation basins, the top of described primary sedimentation pond is provided with catalytic oxidation groove, the bottom of described catalytic oxidation groove is provided with the hole being communicated with described primary sedimentation pond, described catalytic oxidation groove is provided with the pipeline that is connected to described secondary sedimentation basins, in described catalytic oxidation groove, is provided with a plurality of blodiscs, and described a plurality of blodiscs are arranged in series vertically; This blodisc equipment also comprises water circle device, described water circle device comprises a plurality of water wheels that are arranged on blodisc end face and is positioned at the distributing trough that this blodisc is provided with same end face one side of water wheels, described distributing trough connects and composes by three sections, wherein, centre is the water receiving section of level attitude, two ends are the water exit end that is "eight" shape, and the water outlet of described water exit end is connected to described primary sedimentation pond.
When water wheels are positioned at the bottom of blodisc, the in-built full water of water wheels, rotation along with place rotating disk, when taking the top of rotating disk to when water wheels, water in water wheels flows in the distributing trough of rotating disk one side gradually, because the end of distributing trough is communicated with primary sedimentation pond, therefore, the interior sewage backflow with a large amount of living microorganisms of oxidation trough is in primary sedimentation pond, the present invention has broken the technical process of traditional blodisc, having realized the water outlet of blodisc process section can not increase under the prerequisite of any extra power, be back in primary sedimentation pond, complete the biological recirculation between catalytic oxidation groove and primary sedimentation pond,
Further, in described water circle device, the number of water wheels is 4-6, and along place biological runner circumferentially uniform.The receipts water end (W.E.) of described water wheels is 45 ° of oblique angles.
Compared with prior art, the invention has the beneficial effects as follows:
As shown in Fig. 3-1 and Fig. 3-2, the present invention carries out integrative installation technology by primary sedimentation pond, blodisc and secondary sedimentation basins, for ease of the operation of water circle device, provides certain operation basis.
The present invention is equipped with water circle device on the blodisc of series connection, realized recirculation biological between catalytic oxidation groove and primary sedimentation pond, recirculation can make primary sedimentation pond upper strata keep the state of oxidation, increases the capacity of resisting impact load of whole treatment system, improves processing efficiency.
