| 摘 要： | 利用厌氧氨氧化絮状污泥和厌氧颗粒污泥启动厌氧氨氧化颗粒污泥UASB反应器,通过调整进水基质浓度及上升流速培养富集厌氧氨氧化颗粒污泥。反应器经过140 d的运行,成功培养出厌氧氨氧化颗粒污泥,NH;-N和NO;-N去除率分别达到96.41%和99. 11%,总氮去除负荷可以达到 0.26 kg/(m3 - d),并且 ANO;- N/ANH;- N 和 ANO3^- N/ANH;-N 分别为1. 32 ±0. 02和0. 26 ±0. 01,符合厌氧氨氧化化学反应计量学规律。反应器启动过程中厌氧颗粒污泥经历了解体、重组,颜色由黑色变为灰色最终变为红色,经过160 d的运行后形成1 ~3 mm的厌氧氨氧化颗粒污泥。

| Abstract: | Anammox granular sludge-based UASB reactor was started with the Anammox floc sludge and the anaerobic granular sludge. The Anammox granular sludge was cultured by adjusting the influent substrate concentration and the upflow velocity. After 140 days of operation, the Anammox granular sludge was cultured successfully, and 96. 41 % of NH;- N and 99. 11 % of N02~一 N were removed respectively, with total nitrogen removal loading (NRR) of 0. 26 kg/( m3 ? d) achieved. The ratios of ANO^- N to ANH;- N and ANO3^- N to ANH4+一 N were 1. 32 ± 0. 02 and 0. 26 土 0. 01 , respectively, which complied with the chemical reaction stoichiometry of Anammox. During the start-up period of the reactor, the morphology of anaerobic granular sludge underwent the process of disintegration and recombination, and the color changed from black to gray and finally to red, with the Anammox granular sludge of 1 - 3 mm formed after 160 days operation. |
