The purified culture tail water flows through the filter dam into the ecological purification zone, and the aquatic plants and animals in the ecological purification zone can form a multi-trophic level biological system to further assimilate nutrients and purify water. The solid-liquid separation zone is composed of a pool body, a water retaining facility and water inlet and outlet, with a depth of 2.0 m to 2.5 m, for the culture tail water to stay and store for a certain period of time. The purification module mainly promotes the separation of solid particles suspended in the water body by gravity settling, so it has obvious effect on reducing suspended solids, total nitrogen, total phosphorus and chemical oxygen demand. According to literature summary, the area of the solid-liquid separation zone can account for about 40% of the area of the tail water treatment facility, and a water retaining facility can be installed inside to increase the hydraulic retention time of the culture tail water in the area and promote the sedimentation and removal of particles.
[0004] The water retaining facility of the solid-liquid separation zone can be made of sand, reinforced concrete and stainless steel. Sand is easy to obtain and low in price, but it has the risk of collapse under the long-term scouring action of water flow; the reinforced concrete structure is firm, but it is difficult to maintain and remove for reconstruction after construction; and the stainless steel material can be built according to the module, with wide applicability, but the material cost is high. Therefore, how to conveniently and cheaply prolong the hydraulic retention time of the culture tail water in the solid-liquid separation zone is the key to improving the ecological management effect of the two dam three area.
