Abstract:

In the same anaerobic sequencing batch reactors, respectively used aerobic flocculent sludge and anaerobic granular sludge as inoculation sludge to explore the start-up of ANAMMOX reactor. After 70 and 40 days, the ANAMMOX reaction has appeared. Then through increasing the concentration of ammonia nitrogen and nitrite nitrogen to improve the activity of denitrification of the sludge, in the 120 d, the removal rate of ammonia nitrogen and nitrite nitrogen in the two reactors respectively reached to 44.6%, 57.5% and 64.2%, 71.7%, and the ratio of the amount of ammonia nitrogen reduced, nitrite nitrogen reduced and nitrate nitrogen increased was 1:1.28:0.23 and 1:1.23:0.23, which close to the theoretical value(1:1.32:0.26).

Key words: anaerobic sequencing batch reactor, ANAMMOX, denitrification

摘要：

采用自制厌氧序批式反应器(ASBR), 分别以好氧絮状污泥和厌氧颗粒污泥为接种污泥探究厌氧氨氧化反应器的启动情况。分别经过70、40 d的培养, 厌氧氨氧化反应得以发生。随后通过加大进水基质浓度来提高污泥的脱氮活性, 到第120天时, 两个反应器对氨氮和亚硝氮的去除率分别达到了44.6%、57.5%和64.2%、71.7%;其中氨氮去除量与亚硝氮去除量和硝氮生成量的物质的量之比分别为:1:1.28:0.23和1:1.23:0.23, 接近理论值(1:1.32:0.26)。
