Description
Technical field
The utility model is related to processing unit field of the high-concentration ammonia nitrogenous wastewater except ammonia denitrogenation more particularly to a kind of deflector types
Except ammonia denitrogenation biological aerated filter.
Background technology
Ammonia nitrogen processing method mainly has evaporation, gas method, blow-off method, guanite chemical precipitation method, ion exchange at present
Method and bioanalysis.Wherein, in addition to bioanalysis, other methods are materilization freatment method, have cost of investment height, operating cost
Height cannot stably reach the shortcomings of standard.And bioanalysis removes ammonia nitrogen and is concentrated mainly on the waste water that ammonia nitrogen concentration is less than 150mg/L
In processing, seldom between the research of 500-700mg/L Biochemical methods and application to ammonia nitrogen concentration, mating treatment process is more
It is few.
Biological aerated filter is widely used in sewage disposal, but the ammonia nitrogen waste water of biological aerated filter processing high concentration
When, when particularly influent ammonia nitrogen is more than 400mg/L, there is larger fluctuation in water outlet ammonia nitrogen；In addition when wastewater effluent requires TN,
It is even more impossible to realize the up to standard of total nitrogen for conventional aeration biological filtering tank process.For above deficiency, the base in conventional aeration biofilter
On plinth, the structure of biological aerated filter is improved.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of scientific structure design to close
Reason, can supplement basicity or carbon source, except a kind of good deflector type of ammonia denitrification effect removes ammonia denitrogenation biological aerated filter.
To realize that the utility model provides following technical scheme：A kind of deflector type removes ammonia denitrogenation biological aerated filter, mainly
Including filter tank, the filter tank left side wall top is equipped with water inlet, and right side wall top is equipped with water outlet, is equipped in the filter tank several

The upper wall and lower wall in filter tank are vertically connected on, is equipped with support plate between two pieces of baffle plates, the support plate is hung down with two pieces of baffle plates
Direct-connected to connect, the support plate is equipped with filler frame, forms cloth aquaporin between two baffling filter elements, the water distribution leads to
Medicament supplementary device is equipped at the top of road, the medicament supplementary device is Arc grid frame, and one end is connect with baffle plate, the other end and
Filter tank upper wall connection, the medicament supplementary device is interior to be equipped with basicity medicament or carbon source.
Preferably, the height of the baffle plate is the 4/5 ~ 5/6 of filter tank height.
Preferably, equipped with filtrate in the filler frame, the filtrate is volcanic rock, activated carbon, haydite, clinker, poly- ammonia
One or more of ester modified filler, the height of the filtrate are more than the 1/2 of filter tank height.
Preferably, the basicity medicament is one or more of sodium carbonate, sodium bicarbonate or sodium hydroxide.
Preferably, the number at least two of the baffling filter element.
The usefulness of the utility model：Waste water enters cloth aquaporin by water inlet, then enters containing filtrate
Baffling filter element, under conditions of oxygenation, ammonia nitrogen, organic matter in waste water etc. and the filler of biofilm come into full contact with, realize
The degradation of organic matter or the nitration reaction of ammonia nitrogen, by baffling filter element treated waste water, by medicament supplementary device into
Enter to next cloth aquaporin, carbon source supplement or basicity medicament supplement are carried out in medicament supplementary device, under conditions of simultaneous oxygen,
It is come into full contact with the bacterium on filtrate, realizes the denitrification of nitrate nitrogen, complete the abjection of total nitrogen.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：1 it is filter tank, 2 is water inlet, 3 is water outlet, 4 is baffling filter element, 4.1 is baffle plate, 4.2 is branch
