Description
Technical field
The invention belongs to technical field of biological sewage treatment, and in particular to a kind of continuous stream A/O dephosphorization series multistages A/O is certainly
Support device and application process that denitrification process handles low carbon source urban sewage.
Background technology
Traditional biological denitrogenation technology is made up of two processes of nitrification and denitrification, and nitrification is exactly nitrifier by ammonia nitrogen oxygen
Nitrate nitrogen is turned to, denitrification is exactly that nitrate nitrogen is reduced to nitrogen by denitrifying bacterium by the use of organic matter as carbon source, from
And reach the purpose for removing nitrogen from water.Biological phosphate-eliminating technology mainly absorbs organic matter releaser using polyP bacteria in anaerobic zone
Interior phosphorus, excessive suction phosphorus effect then occurs in aerobic zone and is absorbed into the phosphorus in water in vivo, takes off phosphorus from water so as to reach
The purpose removed.Biological denitrificaion is can be seen that from the principle of above biological carbon and phosphorous removal and biological phosphate-eliminating is required for organic carbon source, because
This, organic carbon source will result in the two competition for organic carbon source when not enough, and then cause bio-denitrifying sewage phosphor-removing effect
It is deteriorated.
Generally setting and drainage pipeline networks due to China's septic tank is longer, causes municipal sewage organic carbon source to lack, it is impossible to
Meet demand of the traditional biological denitrification dephosphorization technique to organic carbon source.In this case municipal sewage plant is for row up to standard
Put, typically demand of the biological carbon and phosphorous removal to organic carbon source is met by adding outer carbon source (e.g., methanol), so as to cause sewage
Processing cost is significantly increased.In recent years, continuing to develop with sewage treatment area, some new biological carbon and phosphorous removal skills
Art has obtained significantly developing, including：Synchronous nitration and denitrification technology, short-cut nitrification and denitrification technology, denitrification are removed
Phosphorus technology, Anammox denitrification process and whole process autotrophic denitrification technology etc..Wherein Anammox autotrophic denitrification technique needs
By the NH of part4 +It is oxidized to NO2 -, the NO then obtained2 -Reoxidize the NH of remainder4 +, it is finally reached the purpose of denitrogenation.This
During 1mol NH4 +0.8mol O only need to be consumed2；Only with CO2As carbon source, the consumption without organic matter.With traditional biological
Denitrification process is compared, and Anammox autotrophic denitrification technology can save 100% organic carbon source consumption, can save 60% aeration
Amount, can reduce by 90% sludge yield, so as to greatly reduce the direct energy consumption and operating cost of sewage treatment process, detest simultaneously
The raw water organic carbon source that anaerobic ammonium oxidation biological denitrificaion is saved, can fully meet demand of the system for biological phosphate-eliminating.
Therefore, to meet the energy-saving requirement of sewage disposal, while realizing that the water outlet nitrogen phosphorus of low carbon source urban sewage reaches
Mark, researches and develops the municipal sewage denitrification dephosphorization technique based on anaerobic ammonia oxidation process and has important practical significance,
In addition successful application of the anaerobic ammonia oxidation process in high-ammonia-nitrogen sewage such as sludge-digestion liquid and percolate is that the technology exists
Popularization and application in municipal sewage provide technical support.

Organic matter in water inlet removed in continuous stream A/O dephosphorization apparatus, it is to avoid because organic matter is present, denitrifying bacteria meeting
The problem of competition being produced with anaerobic ammonium oxidizing bacteria.Low carbon source urban sewage initially enters continuous stream A/O dephosphorization apparatus, is had
Machine thing and phosphatic removal, do not occur nitration reaction；The water outlet of dephosphorization apparatus enters multistage A/O autotrophic denitrification devices, it is scarce/
In aerobic alternate environment, acted on using short distance nitration and Anammox acts on and realizes going for nitrogen in municipal sewage
Remove, it is ensured that effluent quality, while scarce/aerobic alternate mode ensure that the steady in a long-term of device short distance nitration.
