description The invention discloses a microecological preparation for purifying aquaculture tail water, and relates to the technical field of biological preparations. The compound microbial agent is prepared from the following raw materials in parts by weight: 50-80 parts of an EM microbial agent and 50-100 parts of a nutritional agent, wherein the EM microbial agent is prepared from the following microbial agents in parts by weight: 40 to 50 parts of an acetobacter aceti agent, 10 to 15 parts of a bacillus agent and 10 to 20 parts of a nitrifying bacteria agent; the microecological preparation provided by the invention is safe and environment-friendly, can reduce organic matters in aquaculture water, greatly reduce the content of ammonia nitrogen, nitrite and hydrogen sulfide and chemical oxygen consumption of sludge at the bottom of a pond, effectively improves the water environment of aquaculture tail water on the premise of considering the preparation cost, can be recycled, and is beneficial to environmental protecti
