The invention relates to a method for purifying marine aquaculture wastewater by adopting the bacterium with the nitrification function. The method comprises the following steps: inoculating bacterial strain culture solutions to 500mL of aquaculture wastewater respectively; carrying out sterilization for 20min at 121 DEG C; placing the sterilized culture solutions in a constant-temperature oscillator for culturing; and under the aseptic condition, testing the contents of ammonia and nitrogen, nitrite nitrogen and nitrate nitrogen of a sample. The method provided by the invention is non-toxic and harmless to cultured animals, the process is simple, no secondary pollution is caused, and the adopted nitrifying bacteria is obtained through sludge produced by the marine aquaculture system. The bacterium with the nitrification function belongs to Bacillus sp., is named as nitrification-HN07 strain, is preserved in the Guangdong Microbiological Culture Collection Center on June 1, 2016, and is assessed with the acce
