通过序批实验的方法，直接接种厌氧氨氧污泥，研究了Zn2+对厌氧氨氧化（Anammox)脱氮效能的影响。研究结果表明，当进水Zn2+质量浓度小于2 mg/L时，对厌氧氨氧化生物活性有促进作用，可增强微生物的脱氮效能；当进水Zn2+质量浓度在2 mg/L和4 mg/L之间时，脱氮效能无明显变化，说明对厌氧氨氧化微生物活性无明显影响；当进水Zn2+质量浓度大于4 mg/L，对厌氧氨氧化反应有抑制作用，Zn2+浓度越高，抑制作用越明显。 Zn2+对厌氧氨氧化的半抑制质量浓度（CI,50）为32.3 mg/L，NO2--N与NH4+-N转化比的平均值为1.28。

In order to study the effect of zinc ions on nitrogen removal of anaerobic ammonia oxidation (Anammox) process, the sequencing batch experimental methods with Anammox sludge was used. The results showed that when the influent concentration of Zn2+ lower than 2 mg/L, the Anammox bacteria activity was promoted and the nitrogen removal efficiency was increased; when the influent concentration of Zn2+between 2 mg/L and 4 mg/L, the nitrogen removal efficiency did not change and Anammox bacteria activity had no significant effect; when the influent concentration of Zn2+ was higher than 4mg/L, the nitrogen removal efficiency was degraded and Anammox bacteria activity was inhibited with the concentration of Zn2+ increased. The result also showed that the half inhibitory concentration of Zn2+(CL50) was 32.3 mg/L and the average conversion ratio of NO2--N to NH4+-N was 1.28 in anammox process.
