Background technology
Non-steroidanalgetic drug (hereinafter referred to as anti-inflammatory agent, NSAIDs) is widely applied in daily life, is to send out at present
Exhibition is the fastest and applies the maximum amount of anti-inflammatory drug.There is now over one hundred kind, including: aspirin salt, such as aspirin；
Non-acetylsalicyclic Barbiturates, such as magnesium salicylate, sodium salicylate；Non-salicylic acid salt, such as ibuprofen etc..Due to antiinflammatory medical instrument
Having the rapid-action feature little with side effect, wherein the medicine with diclofenac, ibuprofen, acetaminophen etc. as representative occupies
NSAIDs market main share.
After the mechanism of anti-inflammatory agent is entrance human body, after completing the function of a series of antiphlogistic antibacterial, be not absorbed by the body decomposition, its
Parent and partial intermediate are staged through internal circulation system metabolism, and enter environment with the Excreta of the mankind.Because anti-inflammatory agent exists
At the beginning of design, add series of stable and degradation-resistant structure.Anti-inflammatory agent can be stable in the presence of in water environment, so often
Gradually it is pooled in Sewage Plant at different levels by drainage system, then builds up and be emitted in natural water.Its water of this AID
Body dissolubility is strong, it is easy to migrate with sewage.At present, Europe, America partial rivers, lake have been found that the existence of a large amount of anti-inflammatory agent,
The western countries such as European Union have been classified as potential information requirement thing and poison thing with the accumulative murder by poisoning of organism, interference.Meanwhile,
The nitrogen-containing pollutants such as ammonia nitrogen are life water body major pollutants at present, enter urban pipe network also by slop.Therefore, non-
Steroidal anti-inflammatory medicine and ammonia nitrogen frequently form combined pollution, and the threat of this kind of compound pollution is the most gradually valued by the people.
The denitrification process of traditional cities sewage treatment process, is mainly carried out under microorganism drives.Tradition denitrification process needs experience
Ammoxidation-nitrification (aerobic)-denitrification (anaerobism) several stage.Mineralized nitrogen-the aerobic stage a large amount of aerations of needs so that it is
It is converted into nitrate.Therefore, consuming a large amount of electric energy, reaction time is longer.Traditional wastewater factory and office reason is emphasized organic removal,
The general time of staying is shorter, and a few hours were to tens of hours.Therefore cause major part anti-inflammatory agent degradation efficiency low, anti-inflammatory agent
Enter natural water initiation with effluent from WWTP gradually to accumulate in water environment.So, exploitation a kind of energy fast degradation anti-inflammatory agent,
Meet the culturing sludge method of bio-denitrification technology requirement simultaneously, there is the most real meaning.
Autotrophic type ammonia oxidation microbiological (including anaerobic type ammonia oxidation microbiological and aerobic ammonia oxidation microbiological etc.) is utilized to take off
Nitrogen is that the problem solving biological denitrificaion cycle length provides a kind of new approach.Autotrophic type ammonia oxidation microbiological is through suitable training
Support and can form ammoxidation-anaerobic ammonium oxidation sludge, it is achieved from a step denitrification process of ammonia nitrogen-nitrogen, compared with denitrification technology
So that the oxygen consumption of 25-45% can be saved, the denitrifying carbon source of 100%；The sludge yield of this technique is low, can greatly reduce low
The pressure of Treatment of Sludge.In recent years, autotrophic type ammoxidation is the most gradually mined out other functions, such as substantial amounts of resistance to lean nutrition-resistant to ammonia
Nitrogen type table companion microbes is found, and autotrophic type ammonia oxidation microbiological can form Tong Bu removal with table companion microbes through certain operation
NSAID (non-steroidal anti-inflammatory drug) and the ability of ammonia nitrogen.But, the core microorganism in this technique-autotrophic type ammonia oxidation microbiological speed of growth is delayed
Slowly, it is easily subject to the impact of dissolved oxygen and poisonous substance and causes activity decrease, therefore also need to utilize extraneous factor protection micro-with enhancing
Biological activity.Thus, set up a kind of autotrophic type ammonia oxidation microbiological of strengthening and with the activity of its table companion microbes thus strengthen same
It is necessary with the sewage disposal system of the ability of ammonia nitrogen that step removes NSAID (non-steroidal anti-inflammatory drug), meets very much following exploitation energy saving and environment friendly
Synchronize detoxification, the requirement of denitrification organisms water technology development.
Summary of the invention
It is an object of the invention to provide a kind of method removing anti-inflammatory agent and ammonia nitrogen based on sponge iron-ammonia oxidation microbiological system synchronization.
