Abstract
A kind of autotrophic denitrification integrated apparatus for handling high ammonia-nitrogen wastewater and startup method, are aerated, and be up equipped with the gas skirt in upside down funnel shape using the husky head of aeration.Device promotes sludge in gas skirt to flow up in aeration, meanwhile, covering outer sludge can be automatically into cover, and formation is circulated, and can reach more preferable mass transfer effect.Device is by being inoculated with a small amount of granule sludge, in the case where being accumulated without nitrous, gradually steps up aeration quantity, cultivates the granule sludge of more bigger more high load capacities.By 37d, ammonia nitrogen loading reaches 0.47Kg/ (m3.d), the average ammonia nitrogen loading of inoculation particle is reached.The present invention is applied to middle and high concentration ammonia-nitrogen sewage denitrogenation processing, simple in construction, and automaticity is high, and denitrification effect is good, and operating cost is low, the startup available for the autotrophic denitrification integration of culture processing high ammonia-nitrogen wastewater.
Description
Technical field
The present invention relates to Water and Waste Water Engineering and field of environment engineering, more particularly, to it is a kind of handle high ammonia-nitrogen wastewater from
Support denitrification integrated device and start method.
Background technology
Nitrate pollution is one of major reason that current body eutrophication phenomenon takes place frequently, at the same be also sewage disposal with again
The crucial crux of raw reuse, how the nitrogen pollutant removed in sewage of economical and efficient turns into domestic and international experts and scholars and phase
The study hotspot of government department is closed, what China promulgated for 2002《Urban wastewater treatment firm pollutant emission standard》(GB18918-
2002) require that all pollutant discharging unit's effluent qualities are less than 5mg/L for ammonia nitrogen in, total nitrogen is less than 15mg/L." 12 " its people warp
In Ji and social development planning outline, the target of total amount of ammonia emission reduction 10% is clearly proposed.According to newly-increased the binding indicator, such as
What realizes that the target of ammonia nitrogen emission reduction also needs to explore in practice.
It is nitration denitrification technique to apply most sewage water denitrification techniques at present, and the technique first passes through nitrifier by sewage
Ammonium oxidation into nitrate nitrogen, then by denitrifying bacterium using organic matter by nitrate-nitrogen reduction be nitrogen.Traditional sewage water denitrification
Complex operation, operating cost are high and produce a large amount of denitrification sludge, and for problem above, researcher have developed many
Plant new denitrification process, such as short-cut nitrification and denitrification technique, synchronous nitration and denitrification technique, denitrifying phosphorus removal technique, anaerobism ammonia
Oxidation technology etc., wherein anaerobic ammonia oxidation process are most economical efficient sewage water denitrification technique generally acknowledged at present, and its core is logical
Cross anaerobic ammonia oxidizing bacteria using nitrite be electron acceptor by ammonia nitrogen direct oxidation as nitrogen, substantially reduce the anti-nitre of tradition nitrification
The reaction process of chemical industry skill, anaerobic ammonia oxidation process has obvious advantage compared with traditional denitrification process：Anaerobic ammonia oxidizing bacteria
Using nitrite as electron acceptor, organic carbon source is not needed in denitrification process；Nitrifying process only need to be by 1/2 ammonium oxidation to Asia
Nitrate, about saves aeration energy consumption 50%；Anaerobic ammonia oxidizing bacteria is chemoautotrophic bacteria, and sludge yield is only to pass in denitrification process
10% or so of system nitration denitrification sludge yield, greatlys save follow-up sludge treatment expense；In addition, Anammox technology is also
There is denitrifying load high, reduce greenhouse gas emission etc. a little.Anammox technology is applied in high ammonia-nitrogen wastewater processing, can be compared with
Operating cost is significantly saved, significant economic benefit is produced.Anaerobic ammonia oxidation process can be reduced compared with traditional handicraft simultaneously

Culture is abnormal difficult, and the First Anammox engineering startup time is 3 years in the world, and the startup cycle of overlength limits the skill
The Rapid Popularization application of art, in order to shorten the startup time of anaerobic ammonia oxidation process, need to improve reactor to anaerobic ammonia oxidizing bacteria
Withholding ability, anaerobic ammonia oxidizing bacteria is obtained fast enriching, newest result of study shows to form particle in reactor dirty
Mud or add Novel biofilm carrier can strengthened anaerobic ammoxidation bacterium withholding ability, but at present this technology still suffer from certain technology
Problem, including：1. anaerobic ammonia oxidizing bacteria gas deliverability is stronger, therefore causes granule sludge not free settling, is easily lost in water outlet；②
The simple biomembrane process anaerobic ammonia oxidizing bacteria biofilm time is longer, and microbial biomass is relatively low, and reactor for treatment ability is difficult to improve,
And biomembrane is easy to fall off, storage and new construction inoculation are difficult.
To sum up, current Anammox Technique Popularizing application needs to include the problem of solution：How to be enriched with reactor
The anaerobic ammonia oxidizing bacteria of high concentration；The potential loss risk of anaerobic ammonia oxidizing bacteria in reactor how is reduced, the steady of processing system is improved
It is qualitative；How Anammox engineering inoculation difficulty, the reproducibility of enhancement engineering are reduced.Accordingly, it would be desirable to develop a kind of new
Utilization Anammox technical finesse high ammonia-nitrogen wastewater device.
