厌氧反应器中接种高效厌氧颗粒污泥并保持启动后平稳运行。在运行过程中对负荷、 pH、氨氮对产气性能的影响进行研究。研究表明气体产量在一定范围内与进水负荷相关，进水负荷越高，产气量越大；在产甲烷菌的最适pH范围内产气量稳定上升；氨氮浓度升高使废水pH发生变化，破坏厌氧微生物的最佳生存环境，氨氮浓度在1500 mg/L以下时对产甲烷菌没有明显不利影响；氨氮浓度超过1500 mg/L时抑制产甲烷菌的活性，产气量降低，反应器性能下降。

The anaerobic biogas-producing reactor with seeding efficient anaerobic granular sludge and kept running smoothly.During the operation, the impact of load, pH, ammonia nitrogen on gas production performance was studied . The research showed that gas production to a certain extent associated with the water load , the higher the water load and the greater the gas production .Gas production increased steadily in the optimum pH range for Methanogens .The ammonia nitrogen density elevates caused waste water pH to change , destructing the anaerobic microorganism 's best living environment .Ammonia nitrogen concentrations below 1 500 mg/L, no apparent adverse effects to Methanogens , but above 1 500 mg/L the activity of methane -producing bacteria inhibited and lower the gas production , and the reactor performance declined .
