Description
Technical field
The utility model relates to a kind of Anammox integrated reactor of novel partial nitrification.
Background technology
In recent years, Anammox is as a kind of novel bio-denitrification technology, because having high nitric efficiency, and the reduction process cost, and be subject to numerous investigators' favor.Anammox refers to that anaerobic ammonia oxidizing bacteria utilizes ammonia nitrogen as electron donor under the condition of anaerobism, 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.But Anammox needs nitrite as matrix, needs the ammonia nitrogen in waste water is carried out partial nitrification before carrying out the Anammox reaction.Yet there are some Intraspecific differences in physiologicals in nitrite bacteria and anaerobic ammonia oxidizing bacteria, when therefore adopting process integration to process high ammonia-nitrogen wastewater, how to realize that nitrosification and being connected of Anammox become extremely important.
Some parts nitrosification, the Anammox process integration reported at present mainly contain two kinds of forms: a kind of is with two kinds of microorganism single culture, realize waste water semi-hitrosation-Anammox by connection, for example: SBR+ anaerobism class reactor, SHARON+ anaerobism class reactor; Another kind is to realize two kinds of microorganisms mixed culture in same reactor, for example CANON reactor by limiting some control factors.It is used in mainly outstanding following problem of nitrosation-anaerobic ammoxidation aspect: (1) is stronger adaptability because nitrobacteria has, nitrococcus is placed on separately in reactor to cultivate easily causes the nitrobacteria growth, thereby affect the stable operation for a long time of nitrosification effect; (2) because anaerobic ammonia oxidizing bacteria is strictly anaerobic bacterium, and nitrococcus is aerobic bacteria, places it in single reaction vessel, if do not carry out subregion, in any case limit oxygen, dissolved oxygen all can exert an influence to the denitrification functions of anaerobic ammonia oxidizing bacteria; (3) no matter adopt two reactor isolate forsters, still adopt single reaction vessel to cultivate, its water outlet dissolved oxygen is lower, need to carry out reoxygenation to water outlet; (4) Anammox is the reaction that a pH value increases, and nitrosification is a reaction that the pH value reduces, and need to add respectively soda acid when adopting two reactors and regulate the pH value.
The characteristic that has for the existing defective of present nitrosation-anaerobic ammoxidation process integration and nitrococcus and anaerobic ammonia oxidizing bacteria, the design attempts subregion in single reaction vessel, guarantee that mutual growing environment is unaffected, realize again the integrated of nitrosification and Anammox simultaneously.The tail gas of nitrosification process is used for gas lift, realizes nitrosification district and the backflow certainly of Anammox district.Experiment showed, that accordingly the reactor of utility model is conducive to high ammonia-nitrogen wastewater and realizes denitrification of autotrophic organism, can avoid the pH value to the impact of reactor; Avoid the impact of high nitrogen concentration.
