Abstract： |
The present invention is short range nitrifying method realized with inhibitor in aerating biofilter and belongs to the field of sewage treating technology in environment protecting engineering. By using NaClO3 as inhibitor, partial nitrosomonas is preserved while inhibiting nitromonas so as to form short range nitrifying; active sludge is then inoculated into the aerating biofilter and aerated for 3-5 days and water with ammonia nitrogen controlled in 30-80 mg/L is fed and stayed for 1.5-2.5 hr in the air/water volume ratio of 4 to 1 for whole range nitrification; and NaClO3 is added into water to reach 10-20 mmol/L and run for 7-14 days or more time to form short range nitrifying. The present invention realizes short range nitrifying chemically rather by means of strict environment conditions, and has aerating biofilter as reaction carrier and raised short range nitrifying reaction rate. |
