Abstract
A method for preparing a bacterial agent for removing ammonia-nitrogen, including: 1) activating a mixed microbial preparation including heterotrophic nitrification bacteria and aerobic denitrification bacteria; 2) inoculating the microbial preparation including heterotrophic nitrification bacteria and the aerobic denitrification bacteria to a membrane region including a double-layered filler; 3) introducing a culture solution of the microbial preparation to the membrane region from one side of the membrane region at a certain pressure and a certain flow rate to cultivate bacteria and discharging metabolites produced by the microbial preparation from the other side of the membrane region; 4) centrifuging a bacterial liquid obtained from cultivation to yield a concentrated bacterial suspension; and 5) adding a protecting agent to the concentrated bacterial suspension, uniformly dry spraying a resulting mixture to a sterilized carrier to yield a bacterial agent, and sealing the bacterial agent for storage.
