以GAC颗粒污泥为接种污泥研究厌氧氨氧化EGSB反应器快速启动的条件及运行参数。反应器的启动在17 d内完成，总氮容积负荷达到1．62 kg／（m3·d）。采用缩短水力停留时间方式提高反应器负荷，14 d内反应器总氮容积负荷能快速升至1．45 kg／（m3· d ），实验结果表明采用低基质浓度和缩短水力停留时间方式更利于厌氧氨氧化反应器的启动。第18～21 d平均产气速率为1．1 L／h ，用气相色谱仪对EGSB反应器产生的气体进行分析，N2 O、CO2平均体积分数分别为0．8％、0．02％，如何降低气体中N2 O的浓度需要进一步研究。

The aim of this study is to explore the conditions of quick start -up and operation parameters of EGSB reactor with GAC granular sludge as the inoculation sludge .The results show that the start -up of reactor can complete in 17 days and the volume load of total nitrogen can reach 1 .62 kg/(m3·d) .It can rise up to 1 .45 kg/(m3·d) within 14 days through shortening hydraulic retention time (HRT ) .The results also indicate that using low substrate concentration and short HRT is more helpful to the start of the anammox reactor .The average gas generation rate is 1 .1 L/h .The gases produced from EGSB reactor are analyzed by the gas chromatograph and it is found that the average content of N 2 O and CO2 is 0 .8% and 0 .02% respectively .So how to reduce N2 O emission will still be a key factor for anammox application .
