Description
Technical field
The utility model belongs to sewage disposal device related fields, and in particular to a kind of sewage deep biological denitrification apparatus.
Background technique
With China's expanding economy, the propulsion of urbanization process, the case where shortage of water resources, water pollution is aggravated, is increasingly tight
High, the requirement of wastewater treatment and reuse is increasingly urgent to, and since there are sewage collectings, difficult, pipe network is invested for tradition centralization sewage treatment
It is high, take up a large area, the outstanding problems such as construction period is long, wastewater treatment rate and COD emission reduction are seriously constrained, in this situation
Under, decentralized type sewage, which handles integrated technology equipment, becomes the beneficial and required supplement measure of centralized sewage treatment.
Although ammonia nitrogen in waste water can be used at the physico-chemical process such as air lift stripping, ion exchange, chemical oxidation
Reason, but these methods the problems such as there are by-product secondary pollution and low efficiencys.In contrast, bioanalysis is that control water body ammonia nitrogen is dirty
The better method of dye.But in bioanalysis, either traditional nitrification-denitrification or novel short-cut nitrification-denitrification and
Short distance nitration-anaerobic ammoxidation technique all needs the nitrification removal of ammonia and nitrogen by nitrobacteria.And being of nitrobacteria can be certainly
Bacteria, it have the characteristics that from nourish one's nature, aerobic, dependency and produce it is acid, since nitrobacteria passes through oxidation inorganic carbon conduct
Unique energy source, so its is slow for duration, reproduction speed, the nitrobacteria in ordinary activated sludge can not be solved
High concentration and the ammonia nitrogen removal problem of difficult removal.
Existing decentralized type sewage processing equipment, some are paid no attention to only with single aerobic treatment technique, denitrogenation dephosphorizing
Think；For some using single aeration mode, energy consumption is higher；Some takes up an area too big, climate using plant treatments methods such as artificial swamps
It influences, fluctuation of service；Some device integrations are not high, poor processing effect.
In municipal sewage or Industrial Wastewater Treatment, traditional treatment process (grid+setting pot+primary sedimentation tank+aeration tank+
Secondary settling tank+sterilization pool) process is longer, take up a large area, and effluent quality it cannot be guaranteed that.Wastewater treatment in China factory is faced with liter
The demand of grade transformation intensified denitrification and dephosphorization, A2/O-MBR is since its denitrogenation dephosphorizing is high-efficient and the good characteristic of effluent quality is at me
State has obtained extensive concern and scale application.At present the domestic industries company prior art be concentrated mainly on A/O technique,
A2/O technique, SBR technique and and the techniques such as oxygen-MBR, but mostly there is investment, processing cost is high, takes up a large area etc. lacks
Point.
Utility model content
The purpose of this utility model is that aiming at the shortcomings in the prior art, providing a kind of sewage deep biological denitrificaion dress
It sets.
In order to realize the utility model, using following technical scheme: a kind of sewage deep biological denitrification apparatus, including anoxic
Pond, advanced nitrogen storehouse, clear water reserviors, backwash aerating system；The anoxic pond, advanced nitrogen storehouse, clear water reserviors are in turn connected into one
The side of the denitrogenation processing cabinet of body, advanced nitrogen storehouse is equipped with wastewater disposal basin；The backwash aerating system includes that back flushing air exposes
Device of air, back purge system, the setting advanced nitrogen storehouse of back flushing air aerator, and connect frequency conversion air blower, back purge system
One end connects advanced nitrogen storehouse, and the other end connects clear water reserviors；Be respectively equipped on the outside of the advanced nitrogen storehouse central controller and
Total nitrogen detector, total nitrogen detector have detecting head to connect advanced nitrogen storehouse.
Further, biological denitrification reactor is equipped in the advanced nitrogen storehouse.
Further, MBBR reactor is equipped in the advanced nitrogen storehouse.
Further, it is anti-to be separately connected control back flushing air aerator, back purge system, biological denitrificaion for the central controller
Device, MBBR reactor, total nitrogen detector are answered, central controller can distinguish output order according to the index of total nitrogen detector test
Control the running of back flushing air aerator, back purge system, biological denitrification reactor, MBBR reactor.
Further, clear water reserviors side is equipped with backwashing wastewater pipeline and connects wastewater disposal basin.
After sewage enters 80 ~ 110min of anoxic pond reaction, it is input to advanced nitrogen storehouse back flushing air aerator, backwash dress
It sets, the instruction operating reaction that biological denitrification reactor, MBBR reactor are exported according to central controller, total nitrogen detector is examined in real time
It surveys, after reaching preassigned, treated that sewage is input to clear water reserviors is stand-by up to standard.
The utility model has the advantages that (1) the utility model is structurally reasonable, reaction efficiency is high, has preferable denitrification functions.
(2) have stronger adaptability to the variation of water quality and quantity, can the sewage to high-concentration and low-concentration effectively handled.
(3) due to using gas and water collaboration backwashed so that in advanced nitrogen storehouse solids high load capacity cutoff performance
Have and preferably shows.
(4) the utility model installation management is more convenient, has saved the manpower of management maintenance, has also saved the land occupation of equipment
Space.
