Ecological treatment system for mariculture tail water in estuary area

The invention discloses an ecological treatment system for mariculture tail water in an estuary region, and relates to the technical field of water treatment, and the ecological treatment system comprises a first ditch used for receiving tail water discharged from a plurality of culture regions; the sedimentation tank is connected to the drainage end of the first ditch; at least one oxidation aeration tank is connected to the drainage end of the sedimentation tank; a water inlet of the ecological purification tank is connected with a water discharge end of the oxidation aeration tank; the second ditch is connected with the drainage end of at least one ecological purification pond. According to the ecological treatment system for the mariculture tail water in the estuarine region, the water quality purification effect is enhanced through the whole process matched with an ordered process treatment process, so that different treatment processes are more detailed, and the effect that the discharged tail water rea
