In, the aperture of corresponding valve according to sewage actual liquid level in pond, can be adjusted flexibly in controller, so as to discharge after ensureing sewage purification
Water quality.Of course, it is possible to water quality detection sensor is installed in proper drainage pipe position, can if water quality detection is unqualified
Allow normal effluent trough with water inlet cell body connect, realize backflow repeatedly sewage is handled, until effluent characteristics meet the requirements for
Only.
A kind of efficiently enhanced denitrogenation filter tank, design feature provided by the utility model are as follows：
(1) it is a kind of upstream biological filter, i.e.,：Processed sewage is needed to flow through filler by direction from bottom to top,
During using this kind of mode, overcome it is lower to stream cover oxygen to remove TN influence, reduce adding for carbon source.
(2) backwash air inlet pipe, the big resistance water distribution system of annular water inlet and backwash water inlet pipe are what spiral wound was formed
Body, and multiple drainings or steam vent are evenly equipped with body, using this kind of mode, because osculum or steam vent uniformly divide
Be distributed in below filler, therefore, there is the advantages of water distribution uniform air distribution, both extended the service life of filler, prevent filler due to
Part is washed and forms the generation of the situations such as leak；On the other hand, in water distribution, due to sewage and filler is full and uniform connects
Touch, this improves sewage treating efficiency；On the other hand, when carrying out backwash, backwash water or backwash gas and filler are full and uniform
Wash away contact, so as to comprehensively to filler carry out backwash, improve backwash effect.
Filler carry out sewage disposal principle be：The denitrifying bacterium for being grown in filter material surface utilizes the carbon in carbon source or waste water
NO in source and waste water3 --N、NO2 -- N, in DO<Anti-nitration reaction is carried out under 0.5mg/l weakly alkaline environment, mainly removes sewage
In TN, while acted on using the Co metabolism of microorganism, remove the organic pollution of part difficult degradation in sewage, and retain sewage
In suspended material (SS), reach remove pollutant purpose.
Waste water processes are as follows：
Sewage in water inlet cell body 2 is evenly distributed sewage in EDNF sections by the big resistance water distribution system 7 of annular water inlet
On, the total nitrogen in sewage is removed by the biological bacteria in filtrate, the qualified water after processing flows into through backwash effluent trough 20
Normal effluent trough 3, then it is discharged into normal outlet pipe.
Operation a period of time (24-72 hours) to EDNF afterwards, it is necessary to carry out backwash, to ensure EDNF removal efficiency.Instead
When washing, cloth water control valve 13 is closed, opens backwash inlet valve 11, descending liquid control valve 16 is opened, passes through downspout first
The sewage retained in pond body is excluded, and when liquid level is reduced to setting value in EDNF ponds (it is lower 1m than normal level, pass through liquid level
Meter controls to adjust), backwash blower fan is opened, gas is evenly arranged on pond body section by backwash air inlet pipe, and pass through filter plate
Filter system carries out secondary gas distribution, gas is more uniformly distributed in pond, after gas cleans 3-5 minutes to filtrate, opens
Backwash water pump, enter ENDF ponds through backwash water inlet pipe, uniform water distribution is carried out by filter plate filter system, clear water is with gas to filtrate
After carrying out combined cleaning 3-5 minutes, blower fan is closed, after clear water rinsing 3-5 minutes, closes backwash water pump, backwash waste is through backwash
Effluent trough is discharged into backwash drainpipe..
Efficient enhanced decarburization biofilter (EDNF) is provided with the big resistance water inlet water distribution system of independent annular, independent
Backwash gas distribution system and independent backwash water distribution system, the big resistance water inlet water distribution system of annular are arranged on above filter plate filter,
Even is distributed to sewage and its carbon source on the cross-cutting fault in filter tank, solves dispersed into water even water distribution and pollutant
Problem.
The utility model also solves influence of the dissolved oxygen (DO) to denitrogenation filter tank, improves the effective time of denitrogenation filter tank processing
And removal efficiency, it is specially：During the backwash of denitrogenation filter tank, common denitrogenation biological filter generally use full-water level backwash, during backwash gas
Between it is longer, influence the environment (DO increases) in denitrogenation filter tank, EDNF Chi Ding set ultrasonic level gage, (anti-using backwash after descending liquid
It is lower 0.8m than normal water outlet liquid level during air purge), shearing force of the gas in filter tank can be increased, can quickly clean filtrate top layer
Inertia biomembrane, the backwash time is reduced, the backwash gas time is the 50-60% in common denitrogenation filter tank, reduces DO to denitrogenation condition
Influence, while reduce the loss of filtrate and coming off for active biological film.
In practical application, increase the percent opening of filter plate filter into water water distribution system because that need not take into account, filter gap is by tradition
2mm bring up to 3mm, independent backwash water distribution system resistance is set and reduced, can on the premise of backwash even water distribution is met
The energy consumption of backwash water pump more than 10% is reduced, simultaneously as the change of backwash mode, the energy consumption of blower fan 40% when can reduce air purge.
Therefore, overall reduction energy consumption.
In the utility model, filter gap is brought up into 3mm by 2mm, prevents little particle filtrate and dirt from blocking filter；Separately
Outside, water inlet even water distribution, organic matter is uniformly dispersed in filter tank cross section, and then biofilm development is uniform, therefore filter tank section hinders
Power is uniform, and because of backwash water distribution and backwash uniform air distribution, cleaning is uniform, should not result in blockage, short stream and channel.
Through experiment, using filter tank provided by the utility model, nitrogen removal efficiency improves 20-30%；Backwash operation energy consumption drops
Low more than 30%.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching should also regard the scope of protection of the utility model.
