Description

A kind of high ammonia nitrogen organic waste-water treating apparatus of continuous flow
Technical field
The utility model belongs to water-treatment technology field, and in particular to a kind of high ammonia nitrogen treatment of Organic Wastewater dress of continuous flow It sets, different types of high ammonia nitrogen such as the applicable coking wastewater of the utility model, landfill leachate, sludge-digestion liquid, gourmet powder waste water Organic wastewater.
Background technology
At present tradition and compared with the wastewater biological denitrificaion technique of mainstream be nitrification-denitrification process.There are the problem of it is as follows: For high ammonia-nitrogen wastewater, in order to realize NH4 +- N is to NOXThe conversion of-N, nitrifying process need to increase oxygen-supplying amount to tie up The activity of ammonia oxidizing bacteria and nitrite-oxidizing bacteria is held, this can undoubtedly increase the capital expenditure of processing system and oxygen supply power Expense;For high ammonia nitrogen organic wastewater, the higher phenomenon of high ammonia-nitrogen wastewater generally existing raw water pH value is not directly suitable for giving birth to Object processing needs to add acid and carries out neutralization adjusting to raw wastewater, while can reduce the balance basicity in waste water.And in Practical Project In, often aoxidize 1mg NH4 +- N is NOX- N need to consume 7.1mg basicity, and follow-up nitrifying process needs a large amount of basicity, commonly required When basicity deficiency, it usually needs additionally add a large amount of basicity and carry out inorganic carbon source during additional nitration, this is one very big Processing cost.
There are a large amount of free ammonias in high ammonia-nitrogen wastewater, research shows that:The meeting when influent ammonium concentration is higher than 500mg/L Toxic effect is produced to nitrobacteria activity, the processing capacity so as to cause entire processing system declines to a great extent, or even can lead Entire biochemical treatment system is caused to collapse completely;It is as follows that there are problems in conventional waste water treatment process:High ammonia nitrogen (such as landfill leachate 1000~8000mg/L of ammonia nitrogen concentration) limitation, lead to not the treating capacity for improving entire biochemical system.General Practical Project mistake Cheng Zhong mostly uses greatly tap water and is diluted to raw wastewater, and originally water dilution method not only increases treatment scale, investment, running cost With, and it is unfavorable for effective operation of biochemical device.The concentration that nutrient matrix is reduced after raw water dilution, is unfavorable for carrying for MLSS Height is unfavorable for hard-degraded substance and the removal of COD.
When handling the relatively low high ammonia-nitrogen wastewaters of C/N, organic carbon source there is a serious shortage of be its nitric efficiency not improving Barrier, it is desirable to provide sufficient outer carbon source maintains the heterotrophic denitrification of denitrifying bacterium, to realize NOX- N is to N2Turn Change.Traditional biological denitrification process there are the problem of it is as follows:It needs to expend a large amount of energy and carbon source.
Compared with traditional heterotrophic denitrifying Bacteria, autotrophy anaerobic ammonia oxidizing bacteria has low, micro- without additional carbon, sludge yield The features such as bioactivity is high, matrix affinity is high, therefore the novel autotrophic denitrification technique based on Anammox principle has work Skill flow is short, floor space is small, capital expenditure is few, saves zmount of oxygen consumption, reduces carbon emission, and excess sludge is few, is not necessarily to external carbon Many advantages, such as source, at present but anaerobic ammonia oxidation process is less there are continuity run technique and stable operation is difficult.With ring Border pollute getting worse, after anaerobic ammonia oxidizing bacteria denitrogenation ammonia nitrogen residual volume it is more be faced with water outlet nitrate nitrogen and ammonia nitrogen concentration it is higher and It cannot be satisfied the problem of increasingly strict wastewater discharge standard.Cause to be discharged ammonia nitrogen and total nitrogen reason for Exceeding to include following several points: First, organic matter is necessarily contained in practical raw wastewater, result of study shows the presence of organic matter for nitrococcus and anaerobism ammonia There is oxidation bacteria strong inhibiting effect, excessively high organic matter can lead to the collapse of anaerobic ammonia oxidation process;Secondly as anaerobism The ammonia nitrogen and nitrite nitrogen ratio of ammonia oxidation bacteria consumption are 1:1.3, it is difficult to adjust the two ratio in real nitrosation process To suitable ratio, during engineering operation, anaerobic ammonium oxidation tank water outlet undoubtedly will appear remaining higher nitrite nitrogen or Ammonia nitrogen concentration causes the nitrogen of water outlet can be much exceeded;Again, according to the achievement in research of Broda, anaerobic ammonia oxidizing bacteria is theoretical The ammonia nitrogen and nitrite nitrogen ratio of upper consumption are 1:1, the ammonia nitrogen of anaerobic ammonia oxidizing bacteria consumption and nitrite nitrogen ratio are in practice 1:1.3,0.3 share having more is converted into nitrate nitrogen by nitrococcus, therefore traditional Anammox can not make final outflow water Qualified discharge;Finally, it is influenced by water quality and extraneous other conditions, the limitation of Anammox nitric efficiency can cause water outlet Ammonia nitrogen and nitrite nitrogen residual volume.
As seen through the above analysis, there are no a kind of both high in terms of the processing of ammonia nitrogen in high density organic wastewater at present The device of effect, reliable and energy saving, economic stabilization.All there is shortcoming and defect places for various processing units, therefore develop one Kind process route is reasonable, the nitrogen rejection facility of economical and efficient is very necessary.
Utility model content
The utility model is related to a kind of high ammonia nitrogen organic waste-water treating apparatus of continuous flow, it is proposed that a kind of completely new high ammonia nitrogen Technologies for Organic Wastewater Treatment.Processing procedure is without adding any acid-base modifier, organic carbon source and inorganic carbon source, basicity dosage It is less, it solves the problems, such as continuous flow Anammox, not only there is the anti-load impact of high ammonia nitrogen and high disposal load-bearing capacity, but also To temperature fluctuation, toxicant it is adaptable, be easy to restore after being suppressed, have both operating cost is low and sludge yield is few etc. Distinguishing feature.
To achieve the above object, the utility model provides a kind of high ammonia nitrogen organic waste-water treating apparatus of continuous flow, feature Be, it mainly by homogeneous pond, anoxic denitrification pond, No.1 sedimentation basin, micro- oxygen nitrosation film mud coupling pond, No. two sedimentation basins, Aerobic film mud coupling bed is strengthened in Anammox film mud coupling pond, multiple-effect, No. three sedimentation basins are followed in series to form;No.1 sedimentation basin The sludge of precipitation flow to anoxic denitrification pond water inlet front end by blowback;The sludge of No. two sedimentation basins precipitation flow to micro- oxygen Asia by blowback Nitrify film mud coupling pond water inlet front end;The sludge of No. three sedimentation basins precipitation by pump reflux to multiple-effect strengthen aerobic film mud couple bed into Water front end, the excess sludge that No. three sedimentation basins generate are emitted into homogeneous pond;After the clear nitrification liquid part processing of No. three sedimentation basins Waste water homogeneous pond is flow to by blowback, treated for part waste water is as water outlet.
The multiple-effect is strengthened aerobic film mud coupling bed and is at least made of thtee-stage shiplock aerobic mud film coupling pond.
