Technique requires to be 100:5:1 to water inlet carbon N:P ratio, to meet the growth and breeding of microorganism, wants so that water outlet be made to reach discharge
It asks.If the ratio is too high or too low, it will the normal growth breeding for influencing microorganism causes water outlet to can not meet discharge and wants
It asks.In process above operation, in order to make nutriment meet the requirement of 100:5:1, to different types of waste water, need to add
A certain amount of nutriment (such as: carbon source, urea, phosphate fertilizer), this results in the waste of substance, is easy to cause secondary pollution.Together
When also there is the problems such as structure is relative complex, device type quantity is more, takes up a large area.
Newly there is the novel theory such as Anammox, short-cut nitrification and denitrification, denitrification dephosphorization, aerobic denitrification now,
The carbon-nitrogen ratio of wastewater influent can be reduced to 4-5.The above theoretical case history existing at present, but service requirement is harsher,
Such as: 1, anaerobic ammonia oxidation process to the conversion ratio of temperature, ammonia nitrogen, pH, dissolved oxygen, poisonous and harmful substance it is more demanding, such as
There is one to can not meet the normal operation that will affect entire technique；2, control requirement of the short-cut nitrification and denitrification technique to dissolved oxygen
Higher, the too low conversion that will lead to ammonia nitrogen of dissolved oxygen is incomplete, causes water outlet ammonia nitrogen to increase, dissolved oxygen is excessively high to will lead to nitrous state
Nitrogen is changed into nitrate nitrogen.
Therefore, it is necessary to improve to solve the above technical problems the prior art.

Specific embodiment
Embodiment 1:
Dynamic integral type sewage processing unit in the present embodiment as shown in Figure 1:, including for being carried out at biology to sewage
The biochemistry pool 18 of reason and the peripheral-traction purlin vehicle 16 being arranged in biochemistry pool 18 are fixedly installed on peripheral-traction purlin vehicle 16
Servo-actuated aerator 3 for being aerated to the bottom of the biochemistry pool and being rotated with peripheral-traction purlin vehicle.Peripheral-traction purlin
The velocity of rotation of vehicle is adjusted according to the BOD and aeration quantity of water inlet.
Normal nitration denitrification is NH3Generate nitrite anions NO2 -, and then generate nitrate anion NO3 -.Nitrate anion is in anoxia condition
Under, nitrite anions is produced, N is further produced2, referred to as denitrification.Short distance nitration refers to NH3Nitrite anions is generated, not reproduction
Nitrate anion；And N is directly generated by nitrite anions2.It is servo-actuated aerator 3 in biochemistry pool to move with peripheral-traction purlin vehicle 16, makes
There is anaerobism, anoxic, aerobic environment in interval in unit volume in biochemistry pool 18, to reach anaerobic phosphorus release, anoxic denitrification
The purpose of (anoxic denitrification dephosphorization), aerobic nitrification (aerobic denitrification).Because its intermittence oxygen supply, obtains nitrifier centainly
Inhibition, aerobic nitrification process control is changed into the degree of nitrite nitrogen in ammonia nitrogen, the nitrite nitrogen of generation is in anaerobic environment
It is middle nitrogen is directly translated by denitrifying bacterium to discharge, to achieve the purpose that denitrogenation.
The detailed process reacted in unit volume:
Aeration aerating, nitrococcus aerobic nitrification generate nitrite nitrogen, and the aerobic heterotroph in part utilizes dissolved oxygen depletion one
Part carbon source, meanwhile, polyP bacteria aoxidizes the PHB itself stored in vivo using the dissolved oxygen in water, provides energy to absorb in water
Phosphorus, and be converted to Quadrafos and be stored in vivo, so that the dissolved oxygen in water be made to reduce；
After dissolved oxygen in water reduces, it is in anaerobic condition, denitrifying bacterium utilizes the nitrite nitrogen and raw water of aerobic generation
In carbon source carry out anti-nitration reaction, meanwhile, polyP bacteria is aoxidized using the chemical oxygen that the nitrite nitrogen in water provides from body
The PHB of interior storage provides energy to absorb the phosphorus in water, and is converted to Quadrafos and is stored in vivo, achievees the purpose that denitrogenation；
After nitrite is consumed, it is in anaerobic state, polyP bacteria synthesizes PHB using the carbon source in raw water, and will be internal
Quadrafos be discharged into water, do homework for aerobic phosphorus absorption.
It is anti-that whole process contains synchronous nitration and denitrification, short-cut nitrification and denitrification, denitrification dephosphorization, aerobic denitrification etc.
It answers, denitrogenation dephosphorizing can be reduced to the demand of carbon source.Because without anaerobic ammonium oxidation process, to the conversion ratio of temperature, ammonia nitrogen,
PH, dissolved oxygen.Because its intermittence oxygen supply, makes nitrifier obtain certain inhibition, aerobic nitrification process control is turned in ammonia nitrogen
Become the degree of nitrite nitrogen, the nitrite nitrogen of generation is directly translated into nitrogen by denitrifying bacterium in anaerobic environment and releases
It goes, to achieve the purpose that denitrogenation, the demand to carbon source can be reduced, to reduce cost.
In the present embodiment, impeller 15 is additionally provided on peripheral-traction purlin vehicle 16.Impeller 15 can pass through guide rail
