The present invention relates to a multi-layer ecological recirculating aquaculture system. The system comprises an aquaculture pond, a sewage pool, a foods supplying subsystem, and a water quality treatment subsystem. Wherein, the sewage pool is connected to the aquaculture pond, and its relative installation height is lower than that of the aquaculture pond the foods supplying subsystem at least comprises a manure-water cooling processor, a manure-water overflow storing tank, a microalgae cultivation pool, a rotifers breeding area, and a brine shrimp cultivation pool, and its relative installation height is higher than that of the aquaculture pond and the sewage pool the water quality treatment subsystem at least comprises a filter tank, a water purification tank, an overflow storing tank, an enzyme cultivation pool, a microbion cultivation pool, and a photosynthetic bacteria cultivation pool, and its relative installation height is higher than that of the aquaculture pond and the sewage pool. So that, the functions of foods supplying and water quality treatment are provided at the same time.本發明係關於一種多重立體式生態循環養殖系統,設有一生物養殖池;一污水池之相對安裝高度低於該生物養殖池,該污水池係連接至該生物養殖池;一食物供應子系統之相對安裝高度高過於該生物養殖池及該污水池,該食物供應子系統至少包含有一肥水冷卻處理器、一肥水溢流儲存槽、一微藻培養池、一輪蟲繁殖區及一豐年蝦培養池;一水質處理子系統之相對安裝高度高過於該生物養殖池及該污水池,該水質處理子系統至少包含有一過濾槽、一淨水池、一溢流儲存槽、一酵素培養池、一微生物培養池及一光合菌培養池。藉以兼具有食物供應及水質處理之作用。(1)‧‧‧生物養殖池(11)‧‧‧排放管路(2)‧‧‧污水池(21)‧‧‧第一抽水泵(31)‧‧‧肥水冷卻處理器(311)‧‧‧第一供應管路(312)‧‧‧第二抽水泵(313)‧‧‧第二供應管路(32)‧‧‧肥水溢流儲存槽(321)‧‧‧第三供應管路(33)‧‧‧微藻培養池(331)‧‧‧第五供應管路(34)‧‧‧輪蟲繁殖區(341)‧‧‧第四供應管路(35)‧‧‧豐年蝦培養池(41)‧‧‧過濾槽(411)‧‧‧第一輸送管路(412)‧‧‧第三抽水泵(413)‧‧‧第三輸送管路(42)‧‧‧淨水池(421)‧‧‧第二輸送管路(43)‧‧‧溢流儲存槽(431)‧‧‧第四輸送管路(44)‧‧‧酵素培養池(441)‧‧‧第五輸送管路(45)‧‧‧微生物培養池(46)‧‧‧光合菌培養池(A)‧‧‧建築物(A1)‧‧‧第一樓層(A2)‧‧‧第二樓層(A3)‧‧‧第三樓層(A4)‧‧‧透明屋頂
