Method for rapidly starting anaerobic ammonium oxidation reactor

The invention discloses a method for rapidly starting an anaerobic ammonium oxidation reactor. With an up-flow anaerobic sludge blanket digestion adopted, the method comprises the following steps of: adding mixed sludge composed of anaerobic digested sludge and sludge of a secondary sedimentation tank of a sewage treatment plant into a reactor, then adding bamboo charcoal particles with the diameter of 3-5mm, specific area of 14.0-31.2m /g, density of 750kg/m and volume density of 520kg/m ; and under airtight and shading conditions, inputting simulated waste water into a reactor to carry out continuous culture starting, wherein operating conditions are that: temperature of the reactor is maintained to be 25-35 DEG C, pH of waste water is 7.0-8.0, hydraulic power retention period is 24-48 hours, and concentration ratio of simulated waste water ammonia nitrogen to nitrite nitrogen is 1: (1.0-1.5). The method disclosed by the invention is convenient to apply, has low cost, can greatly reduce starting time of the anaerobic ammonium oxidation reactor and has wide application prospect to low carbon nitrogen ratio waste water.
