Lower part between.Bubble is upward along 4 outer wall of diversion pipe and 10 inside of vertical clapboard when air inlet pipe 12 works, at this time 10 outside of vertical clapboard
Sludge flows to inside through 10 bottom of vertical clapboard, forms circulation clockwise, meanwhile, thus the sewage in internal biochemical zone is also moved
Power is promoted, and completes the biochemical effect of sludge settling and sewage.
The household domestic sewage tank of the present embodiment further includes dredging tube 21, and the lower ending opening of dredging tube 21 is located at tank body
22 lower part, for the sludge of 22 lower part of tank body to be sucked out.
The household domestic sewage tank of the present embodiment obtains working principle are as follows: sanitary sewage initially enters in grill frame 2, blocks
Cut sewage in bulk in suspend or floating state pollutant, reduce subsequent processing load.Through grid treated sewage stream
Anaerobic zone is entered by diversion pipe 4 after the catch basin of water collect tank 3, is mixed herein with the sludge of aerobic zone reflux, carries out one
The anaerobic reaction of section time, acidification hydrolization Organic substance in water absorb part nitrogenous compound and are converted into nitrogen and discharge, gather simultaneously
Phosphorus microorganism carries out anaerobic phosphorus release using the dissolved organic matter in raw water；Then the mixed liquor one of sewage and the reflux of aerobic end
It rises and enters anoxic zone, utilizing remaining organic matter in sewage in the denitrifying bacteria in this sludge is carbon source, and the nitric acid of reflux
Salt carries out denitrification denitrogenation；After the completion of denitrification reaction, into aerobic zone, the nitrifier in this sludge carries out nitrification
It is that polyP bacteria carries out aerobic phosphorus absorption to nitrate simultaneously by the mineralized nitrogen in waste water, remaining organic matter is also herein by aerobic bacteria
Oxidation most carries out mud-water separation through sloping plate deposition district afterwards, and water outlet is discharged through external overflow weir 18 and outlet pipe 19, the sludge of precipitating
Part returns to anaerobic zone, and some residual sludge is discharged by dredging tube 20.
Aerobic zone sewage is formed inside using the aeration gas stripping between 4 outer wall of diversion pipe and vertical clapboard 10 by aerobic zone
Clockwise flow comes into full contact with sludge and organic matter, improves treatment effeciency, the work of nitrifier and polyP bacteria in this sludge
With, by the mineralized nitrogen in waste water be nitrate simultaneously carry out aerobic phosphorus absorption, residual organic substances are also oxidized.Water warp after biochemistry
Internal weir 15 is back to anaerobic zone along 16 a part of aqueduct, and another part flows into inclined plate area.
This technique is in anoxic zone, NO3-- N concentration sharp fall due to denitrification, simultaneously as in denitrification
Carbon source organic matter is utilized in the process, content of organics declines in sewage, NH4+- N concentration is also declined, and is mainly used for thin
The biological cell of bacterium synthesizes.And in aeration phase, under the action of heterotroph, COD and BOD constantly decline, NH4+- N then due to
Digestion and rapid decrease, corresponding NO3-The concentration of-N constantly rises, but its ascensional range is significantly greater than NH4+Under-N
Range of decrease degree, this is mainly due to heterotrophs to produce compensating action to the ammonification of organic matter.
The method process is simple, and device is few, and construction cost is low, and since nitrification liquid flows back, denitrifier is in denitrification process with original
Organic substrates are not necessarily to additional carbon, can also reduce BOD, COD concentration, anoxic zone can rise before being located at aeration zone as carbon source in water
To the effect of biological selector, improve the settling property of activated sludge, is conducive to control sludge bulking, and in denitrification process
The basicity of generation can compensate consumption of the digestion process to basicity
" A2O " treatment process is used in household domestic sewage tank technique of the invention, is met rural domestic waste and is existed
Realize that the function of dephosphorization denitrogenation solves the operation of decentralized type sewage processing technique technological design in the prior art while removing COD
Parameter is inaccurate, blowdown problem not up to standard, and high degree of automation, and operation Operation and Maintenance is simple and convenient, in space layout
Aspect can be used integrated arrangement mode, all devices be arranged in purification pot, and according to the size of processing water, setting is not
With the purification pot of size, be conducive to modularized production, in-site installation is convenient, is in vertical structure knot in addition, having investment cost low
Structure is compact, and occupied area is small, and fluid flowing is not required to external force, and use is simple to operate, and low energy consumption, adaptable feature,
Have the characteristics that good Nitrogen/Phosphorus Removal, is suitble to promote the use of on the ground such as suburb or rural area.
