After the culture tail water enters the sedimentation tank, the culture tail water needs to be retained for a certain time, so that suspended matters in the water body are settled to the bottom of the tank. A filter dam is built between the sedimentation tank and the aeration tank, filter materials with different sizes are filled in a dam body, and the filter materials can be selected from filling media such as broken stones, cobblestones, small stones, palm sheets, ceramic beads and the like, so that the function of adsorbing mud, dirt and microorganisms in sewage can be achieved. The oxidation aeration tank accelerates the oxidation and decomposition of organic pollutants, and can enhance the self-purification capacity of water and improve the water quality. The method is favorable for accelerating the recovery of the water body with black and odorous, poor organoleptic properties and other states to a normal water ecological system.
