The present application provides a 3-D structure for farming. The 3-D structure for farming comprises a first tank and a second tank, which is connected to the first tank by a first pipe a middle structure connected to the first tank by a second pipe and a upper structure superimposed on the middle structure, wherein the upper structure includes a algae culture facility, which is connected to the first tank by a third pipe. The 3-D structure for farming can process the animal wastes and the processed water or air can be reused.本創作係提供一種立體養殖結構。本創作之立體養殖結構,包括:一第一槽體;與一第二槽體,其設有一第一管路與第一槽體連接;一中層結構,此中層結構設有一第二管路與第一槽體連接:以及一上層結構,設置於中層結構的上方,包含:一藻類培養裝置,其設有一第三管路與第一槽體連接。本創作之立體養殖結構可處理養殖動物所產生的廢棄物,並重複使用經處理過後的水或氣體。100‧‧‧立體養殖結構111‧‧‧第一槽體113‧‧‧固液分離槽115‧‧‧液態肥料槽117‧‧‧第二槽體118‧‧‧氣體處理裝置119‧‧‧發電機120‧‧‧中層結構121‧‧‧飼養空間130‧‧‧上層結構131‧‧‧藻類培養裝置C1~C7‧‧‧第一管路~第七管路F‧‧‧藻類過濾裝置P‧‧‧泵A‧‧‧風扇
