Description
Technical field
This utility model belongs to sewage treatment area, is specifically related to a kind of low oxygenation denitrification denitrogenation filter tank system.
Background technology
Nitrogen can cause the eutrophication of water environment, therefore must carry out denitrogenation before nitrogenous effluent enters water body.?
In undressed raw wastewater, nitrogen-containing compound mainly with organic nitrogen such as protein, carbamide, aminated compounds,
The form such as nitro compound and aminoacid exists, and additionally contains part ammoniacal nitrogen, under the effect of antibacterial, has
Machine nitrogen compound decomposition, being converted into ammoniacal nitrogen, the ammonia nitrogen in waste water, under the effect of nitrobacteria, aoxidizes further
For nitrate nitrogen, then in the presence of denitrifying bacteria, by Denitrification, the nitrous that digestion process is produced
Hydrochlorate or nitrate reduction are nitrogen, in denitrification process, denitrifying bacteria need organic carbon source as electron acceptor,
Utilize NO3-In oxygen carry out anaerobic respiration, and in prior art due to sewage enter in denitrification denitrogenation filter tank time,
Have substantial amounts of oxygen to be filled with, it is impossible to causing anaerobic environment, therefore denitrification efficiency is the lowest.
Summary of the invention
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of denitrogenation effect is provided
The low oxygenation denitrification denitrogenation filter that rate is high, automaticity is high, reliable, noise is little, denitrification process oxygenation is few
Cell system.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of low oxygenation denitrification denitrogenation filter tank system, including filter tank, intake chamber and water feed apparatus, described water inlet
Groove is arranged on the top in filter tank, and described water feed apparatus includes water distribution assembly and outlet component, described water distribution assembly
Water inlet be connected with intake chamber, water outlet is provided with for making sewage along the water outlet group in inflow filter tank, medial wall, filter tank
Part.
Described water distribution assembly includes the first water distribution square tube and the second water distribution square tube, and the first described water distribution square tube is along entering
Tank length direction is arranged, and the water inlet of water distribution assembly is arranged in the first water distribution square tube, the second described water distribution side
Pipe is arranged along medial wall, filter tank length direction, and is fixed on medial wall, filter tank, and the outlet of water distribution assembly is arranged on
The bottom of the second water distribution square tube, the first described water distribution square tube and the second water distribution square tube are by multiple water distribution pipes even
Connect.

Row secondary water distribution, then sewage enters the second water distribution square tube, and the outlet of water distribution assembly is arranged on the second water distribution square tube
Bottom, outlet is provided with the bottom baffle hinged by rotating shaft, and bottom baffle can rotate around rotary shaft, works as dirt
When water water inlet is filtered, under gravity, sewage has an impulse force to bottom baffle, and bottom baffle is under momentum effect
Rotate down around rotary shaft, with water distribution assembly outlet formed opening, this opening towards medial wall, filter tank, sewage by
Bottom baffle and medial wall, filter tank are carried out after three water distributions along inflow filter tank, medial wall, and the lower section of bottom baffle is arranged
Position-limit mechanism, can prevent the excessive sewage caused of opening from flowing directly into the drop water aeration that filter tank is formed.When backwash fills
Putting when carrying out backwash, water and gas are formed reverse impact power, at this impulsive force lower bottom part by the motion of filter tank bottom up
Baffle plate is rotated up, and is closed by the outlet of water distribution assembly, prevents the gentle body of water defeated to intake chamber by water distribution assembly
Send.Pass through this utility model, it is possible to reduce directly by the drop water aeration during water distribution of water distribution weir, prevent oxygenation in water
Affecting denitrification effect, additionally sewage is along inflow filter tank, medial wall, filter tank, it is possible to reduce directly making an uproar when water distribution
Sound pollutes, and plant area's noise control is had certain help.
Compared with prior art, this utility model has that nitric efficiency is high, automaticity is high, reliable, makes an uproar
The advantages such as sound is little, denitrification process oxygenation is few.
