| Abstract: | Anaerobic granular sludge, wetland sediment and their mixture (SS ratio of 1∶1) were used as inoculated sludge to start the Anammox reactor in three UASB tanks, and the feasibility of starting Anammox reactor with wetland sediment as inoculum was investigated. The results showed that the USAB inoculated with anaerobic granular sludge didn’t present the obvious Anammox reaction characteristics after 183 days of start-up operation. The USAB inoculated with mixed sludge began to show obvious Anammox reaction characteristics on day 125, which was shorter than USAB inoculated with wetland sediment on day 155. After the start-up and stable operation of the Anammox reactor, the total nitrogen concentration in the effluent could be reduced to less than 90 mg·L−1 under the conditions of the total nitrogen concentration in the influent of 275 mg·L−1 and the load of 0.275 kg·(m3·d)−1. The TN removal rates of the Anammox reactor inoculated with wetland sediments and mixed sludge reached 74.49% and 67.12%, respectively. The high-throughput results showed that the Anammox bacteria in the two reactors were Candidatus Brocadia, and their abundances reached 9.82% and 10.70%, respectively. |
