The invention discloses a culture
tail water treatment system which comprises a primary
settling zone, an enhanced
settling zone, a biological purification zone and an
effluent storage zone, the primary
settling zone is used for collecting culture
tail water discharged from a
seawater pond; the enhanced settling zone comprises a reservoir, a water separation dam and filter dams, the reservoir is divided into a plurality of settling ponds which are arranged side by side in the left-right direction by the water separation dam, the settling ponds on the left side are used for collecting culture
tail water subjected to preliminary settling, every two adjacent settling ponds are communicated through the corresponding filter dam, and the settling pond on the right side is communicated with the biological purification zone through the corresponding filter dam; the biological purification zone comprises an
animal breeding purification pond and a first
plant purification
wetland, the
animal breeding purification pond is communicated with the
sedimentation pond located on the right side through a filter dam, and the
animal breeding purification pond is communicated with the
effluent storage area through the first
plant purification
wetland. When the culture tail water is treated, the
structure and function of the
seawater pond are not changed, the process is advanced, the technology is reliable, economical and reasonable, manufacturing cost and operation cost are low, and management and maintenance are convenient.
