Description
Technical field
The utility model relates to a kind of constructed wetland waste water treatment technology, is specifically related to a kind of constructed wetland device that utilizes Ammonifying bacteria in the hover artificial swamp, to strengthen the decomposition organonitrogen, belongs to the biological sewage treatment field.
Background technology
At present, the removal mechanism of nitrogen mainly includes the ammonification of machine nitrogen, ammonia volatilization, mikrobe in the artificial swamp nitrated/denitrification, plant absorbing and matrix absorption, the nitrogen in the sewage exists with organonitrogen and two kinds of forms of ammonia nitrogen basically.Generally speaking, organonitrogen is become ammonia nitrogen by microbiological degradation.Inorganic nitrogen can directly be removed from sewage and wetland by plant absorbing and through the harvesting of plant as material indispensable in the growing process in the sewage.But the direct absorption of plant only accounts for a part seldom, and main removal approach is to accomplish through nitrated, the denitrification of mikrobe.And in fact, the clearance of most of wetland nitrogen is lower than 30%, can not remove nitrogen well, and therefore, there is the high problem of water outlet ammonia nitrogen concentration in artificial swamp.And ammonification is the initial link in the biological denitrificaion link, is directly connected to follow-up denitrification process; The removal effect and the speed that fully can influence nitrogen in the artificial swamp with decomposition in time of organonitrogen, quantity of Ammonifying bacteria and activity affect the artificial wetland effluent water quality condition again in the water body.
Nitrated is with NH under the effect of nitrobacteria
4 +-N is oxidized to nitrate radical, because Ammonifying bacteria limited amount in the artificial swamp can not be decomposed into NH to organonitrogen fully in time
4 +-N, then nitrobacteria does not just have enough NH
4 +Nitric nitrogen is resolved in-N deoxidation; And nitric nitrogen is the principal mode of plant utilization; Therefore influence follow-up plant to nitrogen assimilation and denitrification, finally caused problems such as hydraulic detention time prolongs, the removal load of the discontinuous and nitrogen (comprising total nitrogen, organonitrogen, ammonia nitrogen, nitric nitrogen etc.) of nitrogen removal process is lower.
In order further to improve the clearance of organonitrogen in the artificial swamp; " Ammonifying bacteria is removed the effect of organonitrogen in the artificial swamp " literary composition of " environmental engineering journal " the 2nd volume the 8th phase (in August, 2008) publication; 5 strain Ammonifying bacterias in the artificial swamp matrix are carried out preliminary evaluation, compared the effect that different Ammonifying bacterias are removed organonitrogen.The result shows, bacillus (
B acillus), Rhodopseudomonas
(Pseudom onas) be the superiority bacteria spp of Ammonifying bacteria in the artificial swamp; The removal effect of Ammonifying bacteria-1, Ammonifying bacteria-2 and Ammonifying bacteria-5 pair organonitrogen is better relatively, has reached 46.2%, 49.4% and 52.6% respectively.But on the whole, the clearance of organonitrogen is still not high.
Chinese patent CN200420047987.4 discloses a kind of two sections SBR process units removing organic pollutant in the sewage and denitrogenation; Include the sbr reactor device; Be provided with aerating system in the sbr reactor device, this aerating system includes pneumatic line, gas meter and the aerator that connects by known technology.This process unit is made up of two sbr reactor devices of difference called after SBR1 and SBR2, in each sbr reactor device, all places 4 kinds of transmitters that connect measurement and control instrument, and its value is respectively the controlled variable as two sections SBR technology operational processs; Whisking appliance is installed in the SBR2; Be provided with between SBR1 and the SBR2 reactor drum water outlet of SBR1 reactor drum is transformed into the water outlet transfer equipment in the SBR2 reactor drum.This patent has solved uncontrollable heterotrophic bacterium and nitrifier and has been in best living environment simultaneously, reduces processing efficiency and the too high problem of outlet water organic substance concentration, but still exists process unit complex structure, problem that processing cost is high.
Summary of the invention
The purpose of the utility model is for solving that ammonia nitrogen removal frank is lower in the artificial swamp, the water outlet ammonia nitrogen concentration high and existing treatment unit complex structure, problem that processing cost is high provide a kind of hover constructed wetland device of effective removal organonitrogen.

The hover constructed wetland device of a kind of effective removal organonitrogen of the utility model is to be made up of the flowerpot of plantation artificial floating island plant, container, the aeration aerating mechanism of containing sewage.The bottom of said flowerpot has hole, grows to outside the flowerpot bottom so that the root system of artificial floating island plant passes the hole of flowerpot bottom; Described flowerpot is suspended in the container of containing sewage, makes the sewage water surface just arrive the bottom of flowerpot; Described aeration aerating mechanism is linked in sequence by aeration head, pipeline, valve to form, and aeration head is arranged in the container of containing sewage.
The container of described Sheng sewage is circular, and volume is 8-10L; The diameter of said flowerpot
Φ=15-20cm, basin is dark
H=5-10cm.
The method of use of the utility model is:
1) select the artificial floating island plant, in the flowerpot of bottom of which has holes, the hole that makes the root system of artificial floating island plant pass the flowerpot bottom grows to outside the flowerpot bottom with the artificial floating island plant growing;
