Technical field
The present invention relates to anaerobic ammonia oxidation reactor, belong to the biological wastewater treatment field.
Background technology
Along with the continuous development of industrial technology, the quantity discharged of nitrogenous effluent increases year by year.Traditional bio-denitrification technology is limited because of denitrification efficiency, and processing cost (aeration, organic carbon source etc.) is higher, is difficult to satisfy high-nitrogen waste water and handles.
Some novel bio-denitrification technologies receive investigator's understanding and utilization gradually in recent years, comprising short-cut nitrification and denitrification technology, autotrophic denitrification technology, SHARON technology, CANON technology, anaerobic ammonia oxidation process or the like.Wherein Anammox is high because of nitric efficiency, and processing cost is low and receive numerous investigators' favor.Anammox is meant that anaerobic ammonia oxidizing bacteria utilizes ammonia nitrogen as electron donor under the anaerobic condition, and nitrite nitrogen carries out biological respinse as electron acceptor(EA), and is translated into the process of nitrogen.This process need not oxygen and organic carbon source, has greatly reduced the consumption of power and energy.It is long that yet present research shows that anaerobic ammonia oxidizing bacteria has a doubling time, and volume is little, be prone to run off, and characteristics such as growing environment strictness cause anaerobic ammonia oxidation reactor to be difficult to start.Therefore developing the anaerobic ammonia oxidation reactor that is suitable for anaerobic ammonia oxidizing bacteria has important practical significance.
In fact the startup of anaerobic ammonia oxidation reactor is exactly the enrichment process of anaerobic ammonia oxidizing bacteria in the reactor drum.The anaerobic ammonia oxidation reactor of having reported at present nearly all derives from traditional anaerobic reactor, comprising: active sludge class reactor drum, microbial film class reactor drum.It is used in the mainly outstanding following problem in Anammox aspect: though have mikrobe and the ability that pollutent fully contacts, still there is a certain amount of sludge loss problem in (1) active sludge class reactor drum (like UASB, ASBR, IC etc.).The anaerobic ammonium oxidizing bacteria doubling time is so low, causes this type reactor start-up time longer; (2) though biofilm reactor has good interception capacity,, microbial film has a strong impact on contacting of pollutent and mikrobe after thickening, be unfavorable for the raising of reactor drum denitrification efficiency; (3) too high ammonia nitrogen, nitrite nitrogen concentration has restraining effect to anaerobic ammonia oxidizing bacteria, is unfavorable for the direct processing of ammonia nitrogen in high density, nitrite nitrogen waste water; (4) more extracellular polymeric is contained in the anaerobic ammonia oxidizing bacteria extracellular, and toughness is strong, is gathered into sludge bulking easily, forms the dead band, influences reactor volume and removes usefulness.
To the characteristic that the existing defective of present anaerobic ammonium oxidation vessel and Anammox mud are had, the design attempts to optimize muddy water mixing contact conditions through whipping appts is set, be convenient to mud in the main reaction region bottom prilling; On main reaction region top filler is set, strengthens holding back of molecule mud; Through the gas lift effect, the gas that utilizes the Anammox reaction self to produce forms from return-flow system simultaneously.Phegma is back to feed-water end dilution water inlet substrate concn, with the ability to bear of enhancing reactor to ammonia nitrogen, nitrite nitrogen concentration, reduces the toxic action of harmful toxic matter to mikrobe.Under upflow velocity and mechanical stirring acting in conjunction that the backflow effect improves, make prilling mud be in fluidized state simultaneously.Experiment showed, that the reactor drum of invention in view of the above helps the quick accumulation and the prilling of anaerobic ammonia oxidizing bacteria, reduce mikrobe and run off; Avoid the impact of high nitrogen concentration, adapt to the water inlet of high nitrogen concentration, improve the denitrification efficiency of reactor drum.
