Method for quick starting of anaerobic ammonium oxidation technology at room temperature in low matrix

A method especially for quick starting of anaerobic ammonium oxidation technology at room temperature in low matrix belongs to the field of urban domestic sewage treatment and regeneration. The method comprises firstly inoculating nitrified sludge having certain nitration function into an upward-flow biology filtering tank using volcanic rocks as filtering materials, and employing a method of continuous aeration and dissolved oxygen concentration control so as to cultivate nitrified biomembrane; secondly, employing a intermittent aeration / anaerobic way to screen and concentrate anaerobic ammonium oxidation (ANAMMOX) bacterium; and lastly adding a certain amount of ANAMMOX bacterium into the reactor after the reactor fully enter into an anaerobic situation to perform rapid induction, andthus reducing starting time. On the basis of appearance of anaerobic ammonium oxidation characteristics, HRT continues to be reduced, water inflow load is raised, and finally starting of ANAMMOX technology at room temperature in low-matrix sewage can be realized. The invention provides a method for quick starting of the anaerobic ammonium oxidation technology at room temperature in low matrix.
