Method for rapidly starting short-cut nitrification-anaerobic ammonia oxidation process

The invention relates to a method for quickly starting a short-cut nitrification-anaerobic ammonia oxidation process, which comprises the following steps of: grinding brucite until the equivalent particle size is less than 2mm, adhering or embedding the brucite on a non-woven fabric carrier in a rolling or pressing manner to obtain a brucite carrier, preparing a sludge suspension by utilizing conventional sludge of a sewage treatment plant, and putting the carrier into the sludge suspension to complete pre-inoculation, thereby obtaining the short-cut nitrification-anaerobic ammonia oxidation process. The method comprises the following steps: introducing pre-inoculated sludge suspension into a short-cut nitrification tank, carrying out continuous aeration cultivation for 2-7 days, stopping aeration, standing for 6-24 hours, sequentially carrying out precipitation and drainage, introducing tap water or sewage to be treated, carrying out aeration again for 12-48 hours, and repeating the processes of standing and
