Description
Technical field
The invention belongs to application field of water treatment, and in particular to a kind of water processing reactor and its application method, main mesh
Be by optimize reactor configuration, give full play to the effect of biological denitrification, nitrate nitrogen in water removed, is suitable for
Processing is by the underground water of azotate pollution, surface water and production and living sewage.
Background technique
Since the usage amount of nitrogenous fertilizer in industry, life and the discharge and agricultural production of aquaculture waste water is continuously increased, make
The Natural Circulation of nitrogen is destroyed, nitrate as a kind of water body common contaminant, be widely present in underground water, surface water with
And in some life production wastes.Human body, which takes in excessive nitrate, can cause high-speed rail hemalbumin disease, in nitrate transformation mistake
The substances such as the nitrosamine formed in journey have " three cause " effect, are formed and are endangered to human health.When TN is higher in natural water,
Measures of Algae in Water Body will rapid flourish, so as to cause water eutrophication phenomenon.In order to further improve water quality of river, mention
High quality of water environment, current existing sewage treatment plant will face discharge of major pollutant standard and be promoted to by original level-one A
IV class standard limit value of water environment quality standard, wherein total nitrogen discharge index is promoted to 1.5mg/L by original 15mg/L, and
The total nitrogen of sewage treatment plant tail water is mainly made of nitrate nitrogen.Therefore, the purification of azotate pollution becomes raising water in water body
The critical issue of environmental quality.
The problems such as water distribution unevenness easily occurs in current existing packed bed denitrification reactor, and filler blocks, greatly reduces de-
Nitrogen efficiency.The object of the present invention is to provide the novel reactor of nitrate nitrogen in a kind of bioanalysis removing water, filling is special in equipment
The denitrification filler of system handles underground water, surface water and production by azotate pollution using microorganism denitrification
Sanitary sewage.
Summary of the invention
For the undesirable problem of conventional sewage processing equipment denitrification denitrogenation effect, in conjunction with above-mentioned background technique, this hair
It is bright to provide a kind of novel denitrification reactor, main contents are as follows: a kind of multilayer assembly type for loading special denitrification filler is filled out
Fill a reactor and its application method.
The technology of the present invention route is as follows:
For special denitrification filler using sulphur as matrix, raw material includes that sulphur, polyhydroxyalkanoate, polylactic acid and acetate form sediment
Powder.Preparation method are as follows: sulphur, polyhydroxyalkanoate, polylactic acid and acetate starch are put into same appearance by a certain percentage
In device, being heated to 180 DEG C to substance is all in molten state, is stirred evenly, and the sieve plate in determining aperture is poured into after appropriate cooling
Granulated filler is made in upper water clock.Sulphur, polyhydroxyalkanoate, polylactic acid and acetate starch mass ratio be 30 ~ 10:5 ~
1:5 ~ 1:3 ~ 1.
Reactor water process flow uses bottom in and top out immersion, is furnished with water inflow control system.It is set in reactor reaction zone
Oxygen removes between layer, detachable filler, is discharged overflow area, and the special filler of 1/2 ~ 4/5 volume is filled between filler.Oxygen is de-
Except layer loads sponge iron, the dissolved oxygen in water inlet can remove, be conducive to the efficiency for improving subsequent bio reaction；Microorganism and filler
Heterotrophic denitrification and autotrophic denitrification effect occur simultaneously for the filler of interior filling, convert nitrogen for nitrate nitrogen, nitrogen exists
Certain disturbance is generated to packing layer during rising evolution in reactor, and there is gas punching effect, prevent the blocking of packing layer；
According to reaction requirement, 2-10 layers of packing layer are laid, every layer of bottom is porous plate, multiple water distribution, sufficiently reacts, keeps water quality reachable
Mark discharge；Water circulating pump is connect outside reactor, increases water velocity in reactor, reduces the dead zone in reactor.
Further improvement of the present invention is: heterotrophic denitrification and autotrophic denitrification while carrying out, different metabolic type it is micro-
Biology is utilized respectively sulphur and organic matter in filler, carries out autotrophic denitrification and heterotrophic denitrification effect, shortens reaction duration,
Secondary pollution problem caused by carbon source excess is avoided simultaneously.The design of detachable packing layer, convenient for the filling and replacement of filler.
The invention has the characteristics that optimizing the configuration of existing microorganism denitrification reactor, it is anti-to avoid traditional packed bed
It answers device easily to block and the problem of dead zone occurs.Break the function that filler in traditional biological filter tank only plays filtering and carrier, it is initiative
Use there is the special filler of denitrification function, filler, which can not only filter, suspended matter and serves as microbe carrier, can also be micro-
Heterotrophic denitrification and autotrophic denitrification are carried out under the action of biology, gives full play to the effect of microorganism, shorten reaction duration.For nitre
Underground water, surface water and the production and living sewage of hydrochlorate pollution provide a kind of anti-nitration reaction that Simple energy-saving easily manipulates
Device.

Specific embodiment
Below in conjunction with attached drawing and by example, the invention will be further described:
Fig. 1 is a kind of multilayer assembly type packed bed reactor structure chart for loading special denitrification filler.
Denitrogenation reactor is established as shown in Figure 1, the multilayer assembly type packed bed reactor internal operation process describes such as
Under:
The activated sludge tamed is added pump by sludge to put into reactor through mending mud mouth 13, is dispersed in activated sludge respectively
Between the detachable filler of layer on 6 filler 5；Raw water through intake pump by water inlet end 1 enter reactor in, homogeneous area 2 with follow
12 mixing of ring water inlet；Water flow gradually rises to 3 region of sponge iron, and mixing water removes the dissolved oxygen in water through sponge iron 3；It is laggard
Enter 6 between detachable filler, in filler filler 5 and microorganism contact generation denitrification；6 between detachable filler
Using porous plate as material, water flow passes through filler from level to level from bottom to top and constantly carries out denitrification component bottom；Rise to top
After settling section 14, partially overflow outflow reactor by water outlet 7, partially by recycle water end (W.E.) 10 through water circulating pump 11 again into
Enter in reactor.The nitrogen generated in denitrification process constantly disturbs packing layer from the uphill process of lower part, avoids reactor
The problem of interior filler blocking causes dead zone.
