| titleOfInvention | Method and device for synchronous partial nitrification and biofilm anaerobic ammonia oxidation |
| abstract | The invention discloses a method and device for synchronous partial nitrification and biofilm anaerobic ammonia oxidation. The method comprises the following steps of feeding sewage into a water inlet tank and adjusting the pH of the sewage to 7.5-8.5; feeding the sewage into a synchronous partial nitrification and biofilm anaerobic ammonia oxidation reactor to come into contact with sludge to have reaction, wherein partial nitrification sludge is firstly added to the synchronous partial nitrification and biofilm anaerobic ammonia oxidation reactor, the temperature of the reactor is controlled to be 30-34 DEG C, and the dissolved oxygen is controlled to be 0.9-1.4mg/L; when the rate of nitrite accumulation of accumulation is higher than 70%, adding anaerobic ammonia oxidized sludge filler and then reducing the dissolved oxygen till the concentration of the dissolved oxygen is 0.5-0.8mg/L; feeding the effluent from the reactor into a settling pond, discharging water after participating; refluxing the sludge out of the settling pond, wherien the reflux ratio is 80-120%. The device for synchronous partial nitrification and biofilm anaerobic ammonia oxidation is also provided by the invention. Compared with the traditional denitrification device, the device disclosed by the invention has the advantages that the floor space and the energy consumption can be greatly reduced; the operating cost is saved, less sludge is generated, and operation and management are simple. |
