Further, the integrated artistic of the process of processing waste water, nitrogen elimination capacity is 3.0-5.0kgN/ (m3.d)。
Generally speaking, the general principle of the process of above-mentioned waste water treatment reactor 100 processing waste water is as follows：
Anammox section uses " short distance CANON " techniques.Waste water relies on biological rotating disk and suspension in Anammox section
The Anammox flora cultivated on filler, by NH4 +And NO2 -Anammox biochemical reaction is carried out as reactant, is converted into
N2, this is the reaction mainly occurred.NO2 -Also electron donor during Microbe synthesis, CO can be used as2For electron acceptor, at this
During NO2 -By CO2Oxidation generation NO3 -。
The water inlet of general CANON techniques is raw water, and the NO in water is then caused by ammonification and nitrosification2 -/NH4 +Concentration proportion is substantially close to 1.Then Anammox is carried out again.Aerobic bacteria and anaerobic ammonia oxidizing bacteria under limited oxygen condition
Interaction will cause NH4 +It is fully converted to N2, while also there is a small amount of NO3 -Produce.Whole process is all autotrophy, is not required to external carbon
Source.The water inlet of CANON techniques is to NH4 +And NO2 -Inherently no requirement (NR).
In the present invention " water inlet of short distance CANON " techniques be by anaerobism section ammonification and anoxic section nitrosation converge it is useless
Water, regulates and controls NO2 -/NH4 +Concentration proportion scope is 1.20-1.35.So short distance CANON techniques are substantially only needed to NH4 +With
NO2 -Anammox biochemical reaction is carried out as reactant, biochemical reaction process is shortened, improves biological treatment efficiency and place
Manage load.Integrated artistic, nitrogen elimination capacity is 3.0-5.0kgN/ (m3˙d).Nitrogen removal rate is more than 90%, and ammonia nitrogen removal frank is big
In 95%.
In short distance CANON techniques, because NO2 -/NH4 +Concentration proportion is suitable, eliminates nitrosation process, can be in anaerobism
Ammonia oxidation bacteria effect is lower directly to carry out biochemical reaction：
NH4 ++1.32NO2 -+0.066HCO3 -+0.13H+→1.02N2+0.26NO3 -+0.066CH2O0.5N0.15+2.03H2O
The anti-substrate concentration impact capacity of biofilm reactor is most strong, is better than granular sludge bed reactor.Water resistant power load is rushed
It is also most strong in various reactors to hit ability.The anti-substrate concentration impact capacity of biological rotating disk combination moving bed is better than general
Biofilm reactor.
And for NO2 -/NH4 +The waste water of concentration proportion over range, " short distance CANON " techniques also have certain buffering
Ability.Even if NO2 -/NH4 +The concentration proportion scope short time is less than 1.20, and " short distance CANON " techniques have certain buffer capacity
, is there is NH of intaking in power4 +When higher, the part aerobic bacteria in short distance CANON techniques still can be smoothly the NH having more4 +
It is oxidized to NO2 -, further carry out Anammox biochemical reaction.Because the biomembrane on biological rotating disk, because and air
By partly contacting, there is aerobic nitrifier, nitrococcus.Disc is as microorganism carrier, in the forming process of biomembrane
Certain anaerobic zone and aerobic zone is formd on turntable, in aerobic zone nitrosation reaction occurs for microorganism, occurs in anaerobic zone
Anammox reacts, in the aerobic zone NH of biological rotating disk outer layer4 +It is partially oxidized into NO2 -；Unreacted NH4 +With generation
NO2 -；Into internal layer anaerobic zone, further reaction discharges nitrogen, while also a small amount of NO2 -；Further oxidation generates NO3 -, it is
The growth of microorganism provides required electronics.
Only need to note the water inlet NO of short distance CANON techniques in the present invention2 -/NH4 +When concentration proportion scope is more than 1.35,
It is noted that being adjusted by shunting door, NO2 -Should not be excessive for a long time.Thus for the dissolved oxygen of anaerobism section ammonification section
The Stringency that limitation is required is substantially reduced.Anaerobism section is mainly amonifying bacteria, and anoxic section is mainly nitrite bacteria, anaerobism ammonia
Oxidation panel is mainly anaerobic ammonia oxidizing bacteria, without being mixed with a large amount of other mushrooms.The efficiency of biological treatment had so both been improved,
Causing the environmental condition of culture flora simultaneously becomes loose.
The process of processing waste water provided in an embodiment of the present invention, optimal group technology is filtered out with reference to many experiments
