Study on ANAMMOX Treatment of Ammonium-Rich Wastewater

Abstract:

ANAMMOX is a biological reaction system that it can convert ammonium and nitrite to N2 without organic matter and oxygen in reactor. The reaction happened in anaerobic conditions, so it needs little energy. But ammonia oxidation belongs to difficult development germ, this restricted the technology application at the industry. The UBF reactor was used to treat ammonium-rich wastewater in the test, and we control the pH is about 8, HRT is 24h and temperature is about 28°C. Abundant ammonia oxidations were cultured succeed in the UBF reactor. Ammonium and nitrite achieve 89% and 92% respectively and the volume load of reactor is 0.773kgTN/m3.d after 100d of operating UBF reactor.
