Technical field
The present invention relates to the processing unit field that high-concentration ammonia nitrogenous wastewater removes ammonia denitrogenation, more particularly to a kind of deflector type to remove ammonia
Denitrogenation BAF.
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, the shortcomings of standard can not be stably reached.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, supporting handling process is more
It is few.
BAF is widely used in sewage disposal, but the ammonia nitrogen waste water of BAF 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 to TN,
Conventional aeration biological filtering tank process can not more realize the up to standard of total nitrogen.Deficiency, the base in conventional aeration biofilter for more than
On plinth, the structure of BAF is improved.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided a kind of scientific structure design is reasonable,
Basicity or carbon source can be supplemented, except a kind of good deflector type of ammonia denitrification effect removes ammonia denitrogenation BAF.
To realize that the present invention provides following technical scheme：A kind of deflector type removes ammonia denitrogenation BAF, mainly includes
Filter tank, the filter tank left side wall top are provided with water inlet, and right side wall top is provided with delivery port, some bafflings are provided with the filter tank
Filter element, the baffling filter element include deflection plate, supporting plate and filler frame, and the deflection plate is two pieces, is respectively perpendicular
The upper wall and lower wall in filter tank are connected to, supporting plate is provided between two pieces of deflection plates, the supporting plate is vertical with two pieces of deflection plates to be connected
Connect, the supporting plate is provided with filler frame, and cloth aquaporin, the cloth aquaporin top are formed between two baffling filter elements
Portion is provided with medicament supplementary device, and the medicament supplementary device is Arc grid frame, and one end is connected with deflection plate, the other end and filter tank
Upper wall connects, and the medicament supplementary device is built with basicity medicament or carbon source.
Preferably, the height of the deflection plate is the 4/5 ~ 5/6 of filter tank height.
Preferably, being equipped with filtrate in the filler frame, the filtrate is volcanic rock, activated carbon, haydite, clinker, poly- ammonia
One or more in ester modified filler, the height of the filtrate are more than the 1/2 of filter tank height.
Preferably, the basicity medicament is the one or more in sodium carbonate, sodium acid carbonate or sodium hydroxide.
Preferably, the number at least two of the baffling filter element.
Usefulness of the present invention：Waste water enters cloth aquaporin by water inlet, then enters the folding containing filtrate
Filter element is flowed, under conditions of oxygenation, ammonia nitrogen, organic matter in waste water etc. fully contact with the filler of biofilm, realize organic
The degraded of thing or the nitration reaction of ammonia nitrogen, the waste water after the processing of baffling filter element, are entered by medicament supplementary device
Next cloth aquaporin, carbon source supplement or basicity medicament supplement are carried out in medicament supplementary device, under conditions of simultaneous oxygen, with filter
Bacterium on material fully contacts, and realizes the denitrification of nitrate nitrogen, completes the abjection of total nitrogen.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1 it is filter tank, 2 is water inlet, 3 is delivery port, 4 is baffling filter element, 4.1 is deflection plate, 4.2 is branch
