Description
Technical field
The present invention relates to sewage treatment area, more particularly to a kind of improvement oxidation ditch circulation dynode system.
Background technology
A/O and A2/ O techniques be the mankind according to Wastewater Treated by Activated Sludge Process sewage general principle, for organic contamination in sewage
Thing（BOD）, phosphorus（P）And nitrogen-containing pollutant（N）And create and carry out most representational sewage treatment process, it is applied also most
To be extensive.A is English word Anaerobic or Anoxic initial, represents anaerobism or anoxic, O is that should be word Oxic
Initial, represent aerobic.Anaerobism, anoxic and it is aerobic be that activated sludge process removes the required biochemical ring of the pollution such as P, N and BOD institute respectively
Border.Therefore, the pollutants such as P, N and BOD in sewage to be removed, it is necessary to provide and build for microorganism good anaerobic environment,
Anaerobic environment and aerobic environment.
Anaerobic environment, anaerobic environment and aerobic environment are separately positioned on single region by traditional A/O and A2/O techniques
Interior, each region is connected by pipeline, valve and water pump etc., certainly will thus cause high Master Cost, civil engineering costs height, occupation of land face
The shortcomings of product is big, operation and maintenance are inconvenient, and operating cost is high.
Oxidation ditch process also known as " oxidation canal ", and a kind of deformation of activated sludge process, continuous ring type reaction tank make biology
Reaction tank, mixed liquor closure aeration channel in the reaction tank are continuously circulated, and oxidation ditch is generally in extended aeration bar
Used under part.Oxidation ditch uses a kind of aeration and agitating device with direction controlling, and the material into reaction tank transmits horizontal speed
Degree, so that the liquid being stirred circulates in closed type channel.Sewage enters unlimited mixed equivalent to entering after oxidation ditch
Close in the circulatory system, polluted in sewage and be constantly diluted, adsorb and decompose, therefore, its clearance is high, and denitrification effect is good.But
It is due to its hydraulic detention time length, sludge age is longer, and phosphor-removing effect is limited.
Applicant applied for Chinese patent CN102180543A on June 22nd, 2010, " efficient stable biology multiplication process
Sewage-treatment plant ", the device will be aerated aerobic zone and be designed as rectangular loop ditch, and water inlet hybrid reaction area, water lifting zone,
Settling zone is arranged in annular ditch, and sewage sequentially enters hybrid reaction area, water lifting zone, aeration aerobic zone and settling zone.Precipitation
Area's water outlet enters next processing structures, and a sludge part is back to hybrid reaction area, and another part is arranged as excess sludge
Go out device.It is good to BOD removal effects due to which employs technologies such as low dissolved oxygen, high sludge concentrations, while also have denitrification effect,
But there is following weak point simultaneously：1）Because it does not have obvious anaerobic zone/anoxic zone, Nitrogen/Phosphorus Removal has very much
Limit；2）Settling zone is arranged to rectangle sedimentation tank, built-in filler, is not suitable for the larger engineering of sewage quantity, is not suitable for producing mud
More situation, and the replacing inconvenience of filler；3）Sludge reflux is mainly by being arranged on the impeller into water hybrid reaction area
To control, conditioning of mud capacity of returns is inconvenient, runs underaction.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided a kind of good denitrogenation and dephosphorization effect, fortune
Row is stable, conveniently, the low improvement oxidation ditch circulation dynode system of expense.
To realize that the present invention provides following technical scheme：Improve oxidation ditch circulation dynode system, including aerobic zone, anaerobic zone
And anoxic zone, the aerobic zone are annular ditch, and Water flow propelling device is provided with aerobic zone；The anaerobic zone and anoxic zone are placed in ring
In shape ditch, public wall is equipped between anaerobic zone, anoxic zone and aerobic zone；Partition wall is equipped with the anaerobic zone and anoxic zone
And diving mixer.
Preferably, the aerobic zone bottom is provided with aeration tube or micro-hole aerator.
Preferably, the anoxic zone internal partition wall is horizontally disposed with, diving mixer stirs positioned at partition wall both sides and diving respectively
The machine level of mixing is arranged oppositely.
Preferably, the anaerobic zone internal partition wall is vertically arranged, diving mixer is respectively positioned at partition wall both sides and inclination pair
To setting.
Preferably, the public wall is provided with some through holes.
Preferably, it is additionally provided with reflux pump on public wall between the anoxic zone and aerobic zone.
Usefulness of the present invention：There is provided obvious anaerobic zone, anoxic zone and aerobic zone, and can be special according to sewage quality
Point will neatly can be combined in a system between three regions or both, with real dephosphorization, denitrogenation and organics removal
Annular ditch is arranged to etc. processing intent, and by aerobic zone, by anaerobic zone, anoxic zone together or the two selects one to be placed on ring
In shape ditch, one of wall of partial common that three regions connect, save and take up an area and construction costs.
