Description
Technical field
The present invention relates to ammonia nitrogenous wastewater treatment technology field, particularly relate to a kind of ammonia nitrogen waste water treatment system.
Background technology
Develop growth rapidly at present along with the industry such as chemical fertilizer, petrochemical complex, the high ammonia-nitrogen wastewater produced therefrom also becomes one of industry development restraining factors; Ammonia nitrogen enters water body, will cause body eutrophication, reduce water body ornamental value, and the NO3-N and NO2-N of oxidized generation also can affect the hydrobiont even health of the mankind.It is reported, there is red tide up to 77 times in calendar year 2001 China marine site, and ammonia nitrogen is the pollution that one of major reason polluted, particularly high-concentration ammonia nitrogenous wastewater cause.Therefore, cost-effective control high density pollution also becomes the important topic of current environmental worker research, obtains the great attention of insider.But current ammonia nitrogen biological treatment mode has to pass through a succession of biological respinse and just can complete, and investment is large, complex structure, processing efficiency are low.
Summary of the invention
For overcoming above-mentioned deficiency, the invention provides a kind of ammonia nitrogen waste water treatment system of effective raising reaction efficiency.
The technical solution used in the present invention is: a kind of ammonia nitrogen waste water treatment system, comprises denitrification reaction groove, is provided with to carry out denitrification reaction denitrifier in described denitrification reaction groove, is also provided with the grid for stopping mud in described denitrification reaction groove; Be arranged at the aerobic seed selection reactor after denitrification reaction groove, described aerobic seed selection reactor comprises aerobic heterotrophic bacterium and aerating apparatus, the centre on described aerobic seed selection reactor top is provided with two-phase shower nozzle, the hydraulic detention time of described aerobic seed selection reactor is less than 6 hours, goes out organic substance in flowing water in order to reduce this second groove; Be arranged at the nitration reaction groove after aerobic seed selection reactor, be provided with the nitrifier going out flowing water processing aerobic seed selection reactor in described nitration reaction groove, and be used for after being arranged at nitration reaction groove being separated the solid phase of nitration reaction groove and the solid-liquid separation tank of liquid phase.
As the further setting of such scheme, in described nitration reaction groove, be provided with the carrier of load nitrifier.
As the further setting of such scheme, described carrier comprises PU foam or tNonwovens carrier.
As the further setting of such scheme, in described nitration reaction groove, the carbon/nitrogen (C/N) of waste water is about 1 to 2.
As the further setting of such scheme, described nitration reaction groove and solid-liquid separation tank go out flowing water or sludge reflux in denitrification reaction groove.
As the further setting of such scheme, before described denitrification reaction groove, be also provided with an anaerobism groove.
Beneficial effect of the present invention is as follows:
1, organic substance in flowing water is gone out in denitrification reaction groove after entering aerobic seed selection reactor, can by the aerobic microbiological huge uptake of aerobic seed selection reactor, and part ammonia nitrogen can be converted to into nitrate nitrogen by nitrifier, and then reduce carbon/nitrogen (C/N) ratio flowing water of aerobic seed selection reactor, nitrifier now in nitration reaction groove can not by the impact of heterotrophic bacterium accelerated accumulation, improve nitrification effect, reach higher ammonia nitrogen removal frank simultaneously.
2, the setting of two-phase shower nozzle on aerobic seed selection reactor, utilize high-efficiency jet aeration thing to strengthen the technology such as transmission mutually, reactor is had, and water retention time is short, the feature of good sewage processing effect.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1, a kind of ammonia nitrogen waste water treatment system, comprises denitrification reaction groove 1, is provided with to carry out denitrification reaction denitrifier in described denitrification reaction groove 1, is also provided with the grid 7 for stopping mud in described denitrification reaction groove 1, be arranged at the aerobic seed selection reactor 2 after denitrification reaction groove 1, described aerobic seed selection reactor 2 comprises aerobic heterotrophic bacterium and aerating apparatus, and the centre on described aerobic seed selection reactor 2 top is provided with two-phase shower nozzle 9, be arranged at the nitration reaction groove 3 after aerobic seed selection reactor 2, the nitrifier going out flowing water processing aerobic seed selection reactor 2 is provided with in described nitration reaction groove 3, and be used for after being arranged at nitration reaction groove 3 being separated the solid phase of nitration reaction groove 3 and the solid-liquid separation tank 4 of liquid phase, the carrier 5 of load nitrifier is provided with in described nitration reaction groove 3, described carrier 5 comprises PU foam, or tNonwovens carrier, described nitration reaction groove 3 and solid-liquid separation tank 4 go out flowing water or sludge reflux in denitrification reaction groove 1, an anaerobism groove 6 is also provided with before described denitrification reaction groove 1.
Principle of work of the present invention is as follows: first the backflow mixed liquor of ammonia nitrogen waste water and nitration reaction groove 3 imports in denitrification reaction groove 1, and therefore influent stream water contains ammonia nitrogen, nitrate nitrogen and COD.Nitrate nitrogen is changed into nitrogen and removes by the carbon source that denitrifier utilizes COD to provide, and ammonia nitrogen is then reactionless.Then, the flowing water that goes out of denitrification reaction groove 1 imports aerobic seed selection reactor 2, two-phase shower nozzle 9 is arranged on the centre on aerobic seed selection reactor 2 top, water circulating pump promotes High-Pressure Water and injects reactor through shower nozzle, because suction function sucks large quantity of air, the acting in conjunction of current and air-flow makes again to form High Speed Turbulent shear zone below shower nozzle, the air dispersion sucked is become tiny bubble, the sewage being rich in dissolved oxygen reaches the bottom of reactor through thrust-augmenting nozzle, upwards reflux forms circulation again, jet under shearing orientation again, so move in circles operation, so sewage is by oxygenation repeatedly, bubble and microorganism cenobium are constantly sheared refinement, and form fine and close tiny flocs unit.Water outlet enters air flotation pool, and partial reflux mixes with water inlet, organism effectively can be taken in cell and be reduced by organic concentration.Remaining ammonia nitrogen and heterotrophic bacterium mixed solution enter nitration reaction groove 3, the heterotrophic bacterium of suspended state and the nitrifier be contacted with on carrier 5 is comprised in this reactive tank, nitrifier can under lower C/N ratio, effectively ammonium oxidation is become nitrate nitrogen, then be back to denitrification reaction groove 1 to remove, finally enter solid-liquid separation tank 4, and nitration reaction groove 3 and solid-liquid separation tank 4 go out flowing water or mud can be back in denitrification reaction groove 1 again, in nitration reaction groove 3, the carbon/nitrogen (C/N) of waste water is about 1 to 2, the growth of nitrifier can be promoted, promote the treatment rate of ammonia nitrogen waste water treatment system, the setting of grid 7 can effective stop portions impurity mud.
