A novel biological nitrification system was designed. It consists of two chambers separated by a cation exchange membrane,an anaerobic fermentation reactor anda biological nitrification reactor. A wastewater is fed into the anaerobic reactor andammonia moves to the nitrification reactor via the cation exchange membrane.Ammonia is oxidized to nitrate by nitrifying bacteria.In a conventional process, organics are removed in an anaerobic fermentation reactor and thenammonia is subsequently oxidized in a nitrifying reactor. Therefore, the total process requires a long period of time and the residual organics inhibit the efficiency of the nitrification. In this system, the ammonia is independently oxidized since the cation exchange membrane allows not the organics but the ammonia to move into the nitrification reactor. |
