Description
Technical field
The invention belongs to biological denitrification consersion unit technical field, and in particular to a kind of enhanced biological water process denitrification
Reaction unit.
Background technology
Polluted by nitrogen, the environmental pollution caused by nitrogen compound.It is mainly nitrogen and nitrogen oxides in air, the latter is straight
Connecing or cause indirectly the major pollutants of air environmental pollution, nitrogen dioxide has strong and stimulating, its toxicity bigger than sulfur dioxide；It
Main produced with life combustion of fossil fuels by industry.There is the gas organic matter such as alkene in air（As contained in automobile exhaust
Much）With nitrogen oxides and when depositing, through solar radiation, photochemical reaction occurs can cause photochemical pollution.In air
Nitrogen dioxide can generate nitric acid or nitrate with rainwater effect, form acid rain, or be deposited to soil with the form of nitrate granules thing
Earth or water body, cause acidifying.
The method of water body denitrification is more, there is Physical, chemical method and bioanalysis etc..Due to cost and secondary pollution etc. because
Element, physics, chemical method denitrogenation range of application it is very narrow.Existing main denitrogenation technology is using biological denitrificaion method.Biological nitration
Reaction can convert ammonia into nitrate, eliminate influence of the ammonia to environment.Importantly, it can combine with anti-nitration reaction, most
Nitrogen is converted ammonia to eventually.In biological denitrificaion, denitrification is the committed step for making in whole process nitrogen depart from water body.
Therefore, efficient anti-nitration reaction equipment is researched and developed to have important practical significance.Existing biological denitrification consersion unit,
Device is main to be developed by activated sludge tank, most commonly A/O techniques.For activity in ensureing device in traditional handicraft
The effective content of sludge, and denitrification is normally carried out, secondary sedimentation tank typically can be built in bioprocess technology rear end, carry out mud
Water is separated.The separation process of activated sludge and treatment water is carried out by second pond, then is sent instead back to activated sludge by reflux pump
Ying Chi.Such operation not only increases equipment, consumes power, and by nitration denitrification bacterium mixed collection, be unfavorable for being formed
Biological flora with obligate treatment effect.Additionally, being also unfavorable for forming the excellent granule sludge of sedimentation function, reactor is caused
Utilization rate is relatively low, and denitrification effect is poor.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of device for being capable of enhanced biological anti-nitration reaction.
The technical solution adopted in the present invention is：A kind of enhanced biological water process anti-nitration reaction device, it is characterised in that：
Reaction unit lower end is provided with into water water distributor, and reaction unit upper end is provided with sludge settling area, sludge settling area lower end
It is provided with sludge reflux seam；Downflow weir is provided between the reaction unit and the sludge settling area.
Beneficial effects of the present invention are：
1st, carry out the microorganism of anti-nitration reaction to exist with the form of granule sludge, anti-nitration reaction efficiency high, mud-water separation effect
It is really good；
2nd, decanting zone is built in the top of conversion zone, and compact conformation eliminates secondary sedimentation tank and sludge reflux facility, reduces
The volume of structures, it is to avoid destruction of the reflux pump to granule sludge；
3rd, reaction sewage is constantly flowed up with certain speed in device, and sewage is fully contacted with granule sludge during up-flow,
Enhance mass transport process；
4th, without dead band in reaction unit, the fluidizing performance of sludge is good, runnability stabilization；
5th, the reaction unit has good biological denitrification performance.
Brief description of the drawings
Fig. 1 is the structure top view of the embodiment of the present invention；
Fig. 2 is the structure front view of the embodiment of the present invention；
In figure, 1- water inlets water distributor, 2- decanting zones sludge reflux seam, 3- sludge settlings area, 4- downflow weirs.
Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, below in conjunction with the accompanying drawings and embodiment is to this hair
It is bright to be described in further detail, it will be appreciated that implementation example described herein is merely to illustrate and explain the present invention, not
For limiting the present invention.
See a kind of enhanced biological water process anti-nitration reaction device that Fig. 1 and Fig. 2, the present invention are provided, under reaction unit
End is provided with into water water distributor 1, and reaction unit upper end is provided with sludge settling area 3, and the lower end of sludge settling area 3 is provided with sludge and returns
Stream seam 2；Downflow weir 4 is provided between reaction unit and sludge settling area 3.
The reaction unit ratio of height to diameter H/D of the present embodiment is 2：4.
The water inlet water distributor 1 of the present embodiment is by a water inlet pipe and some vertical parallel water distributor groups being arranged on water inlet pipe
Into；Water inlet water distributor 1 is embedded in reaction unit bottom, and reaction unit bottom surface level, water-locator plane and reaction unit bottom
The spacing of plane is 150 ~ 200mm.
The sludge settling area 3 of the present embodiment is funnel type region, and the volume in sludge settling area 3 accounts for reaction unit cumulative volume
1/5~1/6。
The sludge reflux seam 2 of the present embodiment is that apsacline stitches body, and the level inclination of inclined-plane bottom is 50 degree ~ 55 degree.
The reaction unit of the present embodiment is built by steel or armored concrete, conversion zone and sludge settling region build jointly in
In same round pond.Carry out the microorganism of anti-nitration reaction to exist with the form of granule sludge, seed sludge is added to reaction zone
The middle part in domain.Sewage is imported by water distributor of intaking, to flow up mode by reaction unit.Sludge settling region and conversion zone
It is connected.Because without excessive hydraulic disturbance, the rate of climb of liquid stream is slower in settling zone, is taken to the sludge of mud chamber
Separated, and gravity and the pulling force return reative cell in Jiang Liu areas by sludge.Water outlet is discharged by decanting zone downflow weir.
The present invention causes that reactor produces a kind of relatively independent biological flora growing environment by the integrated of precipitation zone,
Make in reactor granular sludge using the operation of up-flow simultaneously to improve activated sludge settling property, by granule sludge with
The up-flow mixing of sewage causes good reaction mixing effect so as to improve the capacity utilization of reactor.
Experiment proves that anti-nitration reaction device of the present invention has good biological denitrification performance.In pH=6.5-7.5, instead
Under conditions of answering 25-30 °C of temperature, can Efficient Conversion water inlet nitrate nitrogen and nitrite nitrogen, with reactor utilization ratio high,
Runnability stabilization.
Although this specification has more used water inlet water distributor 1, sludge reflux to stitch 2, sludge settling area 3, downflow weir 4 etc.
Term, but it is not precluded from using the possibility of other terms.Using these terms just for the sake of the more easily description present invention
Essence, be construed as any additional limitation and all disagreed with spirit of the present invention.
It should be appreciated that the part that this specification is not elaborated belongs to prior art.
It should be appreciated that the above-mentioned description for preferred embodiment is more detailed, therefore can not be considered to this
The limitation of invention patent protection scope, one of ordinary skill in the art is not departing from power of the present invention under enlightenment of the invention
Profit requires under protected ambit, can also make replacement or deform, each falls within protection scope of the present invention, this hair
It is bright scope is claimed to be determined by the appended claims.
