| Abstract: | Zeolite has good ammonium absorption capacity and microbial carrier function. Anammox bacteria affected by starvation were activated in a reactor containing zeolite to study the effect of zeolite on the activity and structure of anammox bacteria after long-term starvation. The results showed that anammox bacteria recovered in the zeolite reactor and the control reactor (without zeolite addition) after 82 days of operation. The nitrogen removal efficiency of zeolite reactor began to lag behind that of the control reactor on the 59th day. On the 82nd day of operation, the nitrogen removal load (NRR) of zeolite reactor was 177.8 mgN/(L·d), significantly higher than that of the control reactor (154.3 mgN/(L·d)). At the same time, 16S rRNA high-throughput sequencing method was used to analyze the microbial composition and function of the microbial community in the reactor. It was found that adding zeolite carrier could increase the abundance of anammox bacteria Candidatus brocadia after recovery, and could better promote the recovery of anammox bacteria inhibited by hunger. |
