Abstract
The utility model relates to the field of sewage treatment, in particular to the field of biological sewage treatment oxidation ditch technology. A synthesized oxidation ditch sewage treatment device comprises a ring-shaped oxidation ditch and two sedimentation tanks; a surface aerator is arranged in the ring-shaped oxidation ditch; the two sedimentation tanks are arranged at the central position of the ring-shaped oxidation ditch and have a concentric circle structure with the ring-shaped oxidation ditch. The synthesized oxidation ditch sewage treatment device has the advantages of integrating the two sedimentation tanks and the ring-shaped oxidation ditch for separating mud and water into one facility, thus saving material and location. The adoption of multi-functional surface aerator and an aeration zone to create a guide wall with an angle of 45 degrees ensures stream no backflow any longer and thus conserving energy.
Description
[technical field]
The utility model relates to sewage treatment area, particularly biological sewage treatment oxidation Ditch Technology field.
[background technology]
Trade effluent and sanitary sewage need pass through sewage disposal, and activated sludge process is utilized the microbiological oxidation composition principle, eliminate the organic contamination in the water, are current economical and effective technology of generally acknowledging in the world.Oxidation ditch process is a kind of of activated sludge process, and with respect to the push flowing of blast aeration, it is the full mixed type of mechanical aeration.Therefore it has anti impulsion load and is easy to use and management and the stable characteristics of treatment effect, widely uses at town sewage and Industrial Wastewater Treatment at present.
Existing annular oxygen ditch is what to separate with the secondary sedimentation basins (second pond) of solid-liquid separation, spends more material and takies ground more.Because modern city is densely populated, the soil anxiety, and have a large population, therefore the sewage quantity that needs to handle, needs the little waste disposal plant of floor space with regard to greatly.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of floor space few, and energy-conservation effectively comprehensive oxidation ditch waste disposal plant.
The utility model solves the problems of the technologies described above by the following technical solutions:
A kind of comprehensive oxidation ditch waste disposal plant comprises annular oxidation ditch, second pond; Be provided with surface aeration machine in the annular oxidation ditch; Described second pond is arranged on the central position of annular oxygen ditch, is concentric structure with annular oxidation ditch.
Described annular oxidation ditch is divided into ditch inner region and preposition anaerobic zone; This ditch inner region is divided into outer raceway groove and interior raceway groove by a partition wall; Described surface aeration machine is two, is separately positioned on the top and the terminal of described partition wall.
Angled one first training wall of establishing of the top of described partition wall raceway groove direction outside described; Angled one second training wall of establishing of the terminal of described partition wall channel direction in described.
The angle ranging from 45 °.
Advantage of the present utility model is: the second pond and the annular oxidation ditch that will be used for mud-water separation are integrated into an equipment, save material and land used.And adopt simple and easy advanced person's training wall, and preventing upstream, aeration zone current refluence phenomenon, energy-saving effect is remarkable.Cooperate and adopt multi-functional surface aerator, energy-conservation effective.
[description of drawings]
In conjunction with the embodiments the utility model being done one with reference to the accompanying drawings describes in detail.
Fig. 1 is the utility model schematic cross-section.
Fig. 2 is Figure 1A-A sectional view.
Fig. 3 is Figure 1B-B sectional view.
[embodiment]
Please consult Fig. 1, Fig. 2, shown in Figure 3 simultaneously, a kind of comprehensive oxidation ditch waste disposal plant.Comprise annular oxidation ditch 10, second pond 20; Second pond 20 is arranged on the central position of annular oxygen ditch 10, is concentric structure with annular oxidation ditch 10.
At top near partition wall 13, also annular oxidation ditch 10 peripheries of promptly close multi-functional surface aerator 31 are provided with preposition anaerobic pond 40, be provided with sewage water inlet pipe 51 between preposition anaerobic pond 40 and the annular oxidation ditch 10, also be provided with return sludge pump 61 and residual sludge pump 62 in the preposition anaerobic pond 40.
Be provided with half-bridge scraping and sucking machine 21 in the second pond 20, second pond 20 also is provided with towards the sterilization pool clear water rising pipe 52 of (figure does not show).Circumferential annular water distributor 22 1 ends connect annular oxidation ditch 10, and the other end connects second pond 20.
Sewage enters the preposition anaerobic zone 11 of annular oxidation ditch 10 by sewage water inlet pipe 51, flows into annular oxidation ditch 10 ditch inner regions 12 in the direction of arrows and mixes in the direction of arrows with current after multi-functional surface aerator 31 oxygenations and flow in interior raceway groove 122.Flow is to ditch inner region 12 downstreams, through multi-functional surface aerator 32 oxygenations and promote current outside raceway groove 121 flow in the direction of arrows.Sewage mixes with active sludge in the annular oxidation ditch 10, through the microbial process of aerobic and double oxygen, and the CODcr that degraded, BOD
5And NH
3-N.The aerobic section mixed solution is in circumferential annular water distributor 22 enters second pond 20 in annular oxidation ditch 10, and clear water catchments and delivers to sterilization pool by clear water rising pipe 52 through water leg (figure does not show) after the solid-liquid separation.The precipitation active sludge of second pond 20 is scraped by half-bridge scraping and sucking machine 21 and is drawn to central tube (figure do not show) and delivers to preposition anaerobic pond 40 by sludge pipe 53, be back to annular oxidation ditch 10 preposition anaerobic zones 11 by return sludge pump 61, in preposition anaerobic zone 11, have a liking for that the phosphorus bacterium then discharges phosphorus so that aerobic zone absorbs phosphorus again.Excess sludge drains into water extracter (figure does not show) dehydration by residual sludge pump 62, and phosphorus is discharged outside the treatment system.
Second pond and annular oxidation ditch that the utility model will be used for mud-water separation are integrated into an equipment, save material and land used.And adopt simple and easy advanced person's training wall, and preventing upstream, aeration zone current refluence phenomenon, energy-saving effect is remarkable.Cooperate and adopt multi-functional surface aerator, energy-conservation effective.
