Description
Technical field
The present invention relates to the devices that a kind of endogenous short-cut denitrification of city domestic sewage couples ANAMMOX advanced nitrogen dephosphorization
With method, belong to technical field of sewage, mark transformation, municipal administration life are proposed suitable for newly-built municipal sewage plant or old water factory
The sewage treatment fields such as the processing of sewage and industrial wastewater.
Background technology
In waste water control, the removal to nitrogen is that sewage solves the most thorny issue, and realizes sewage deep disposition
The key of qualified discharge.Classify according to sewage water denitrification principle, physico-chemical process denitrogenation and bioanalysis denitrogenation can be divided into.With physical-chemical process
It compares, the characteristics of bioanalysis shows economical and efficient in nitrogenous effluent treatment, has a wide range of application, while bio-denitrification technology
Development potentiality is huge, consequently only that being only nitrogen most reasonable measure in removal sewage using bioanalysis denitrogenation.

Nitrogen is reduced to the reaction of nitrogen.Anammox is as a kind of efficient biological denitrification process, because its high volume removal efficiency has
There is good development and application foreground.People started from for 20 end of the centurys to the research of anaerobic ammonia oxidation process, the exploitation at the beginning of 21 century
Success has many successful cases in the denitrogenation processing of the high-concentration ammonia nitrogenous wastewaters such as landfill leachate, sludge-digestion liquid at present
Example.
Short-cut denitrification is by nitrate nitrogen (NO3 -- N) reduction process control product be nitrite nitrogen (NO2 -- N), and it is short
Journey nitrification is compared, and short-cut denitrification is smaller by external environment variation, can realize that nitrous accumulates more stablely, to be anaerobism
Ammoxidation reaction provides substrate.Short-cut denitrification is compared compared to traditional complete denitrification, the fast, sludge with nitrogen conversion rate
The advantages such as low output, carbon source demand amount be few；Endogenous denitrification refer to heterotrophic denitrifying Bacteria using the endogenous substance stored in vivo as
Nitrate nitrogen or nitrite nitrogen are reduced to the process of nitrogen by electron donor.Contain a large amount of ammonia nitrogens in municipal sewage, can be used as and detest
One of the matrix of anaerobic ammonium oxidation reaction, but the content of nitrite nitrogen is few in sanitary sewage, it can using endogenous short-cut denitrification
To make full use of the carbon source in sewage to realize the acquisition of nitrite nitrogen.Therefore, anaerobism ammonia oxygen is coupled using endogenous short-cut denitrification
Change the efficient process that may be implemented to sewage.
