Abstract：The performance of anaerobic ammonia oxidation (ANAMMOX) for nitrogen removal from etching wastewater was investigated using an up flow biofilm reactor by inoculating with ANAMMOX sludge．The reactor operation results indicate that etching wastewater was toxic to activity of ANAMMOX sludge as NH4+-N source. Nitrogen removal rate of ANAMMOX reactor was reduced from 3.2 kg/(m3·d) to 1.2 kg/(m3·d) in 14 days, when the concentration of NH4+-N in the influent was 150 mg/L by diluting the etching wastewater. However, the effect of etching wastewater on ANAMMOX sludge was relieved marked by domestication. After 110d domestication, obvious inhibition phenomenon was not observed when the concentration of NH4+-N in the influent was 300 mg/L by diluting etching wastewater. At the same time, nitrogen removal rate of ANAMMOX reactor increased from 1.6 kg/(m3·d) to 6.0 kg/(m3·d). It was suggested that ANAMMOX process could be well applied to printed circuit board industry wastewater treatment with high concentration of NH4+-N through domestication of ANAMMOX sludge.
