Aquaculture water recirculation and purification system and its aeration treatment module having an aquaculture zone, a sedimentation filtration module, an aeration treatment module and a fine filtration module to reduce water consumption
An aquaculture water recirculation and purification system, comprising: an aquaculture zone and a treatment subsystem, which can circulate culture water in the aquaculture zone along water flow direction between the aquaculture zone and the treatment zone by a pressure pump. The treatment subsystem comprises a sedimentation filtration module, an aeration treatment module and a fine filtration module sequentially connected to each other, wherein the sedimentation filtration module is used for having an initial culture-water filtering and sedimenting the sludge of the culture water, the aeration treatment module is used for bending the water flow direction of the culture water several times on the horizontal plane, so that the culture water will contact with air while sequentially flowing through each cut-off wall of the aeration treatment module, and the fine filtration module is used for finely filtering the culture water and bringing the culture water to contact with air, wherein the fine filtration module is planted with a plant.一種養殖水循環淨水系統,包含:一養殖區及一處理子系統,係藉由一加壓泵使該養殖區的養殖水沿一水流方向在該養殖區及該處理區之間循環流動,該處理子系統包含依序連接的一沈澱過濾模組、一曝氣處理模組及一細過濾模組,其中該沈澱過濾模組用以初過濾該養殖水及沈澱該養殖水的淤泥,該曝氣處理模組,用以使該養殖水的水流方向於水平面上彎折複數次,並使該養殖水在依序流經該曝氣處理模組的各截流牆時與空氣接觸,該細過濾模組用以細過濾該養殖水並使該養殖水與空氣接觸,前述細過濾模組栽種有一植栽。(1)‧‧‧養殖區(11)‧‧‧養殖空間(12)‧‧‧出水部(13)‧‧‧進水部(131)‧‧‧石塊(2)‧‧‧處理子系統(20)‧‧‧加壓泵(21)‧‧‧沈澱過濾模組(200)‧‧‧沈澱過濾空間(201)‧‧‧第一側牆(202)‧‧‧第二側牆(203)‧‧‧分隔牆(205)‧‧‧初過濾件(22)‧‧‧曝氣處理模組(221)‧‧‧外牆(222)‧‧‧處理空間(223)‧‧‧擋水牆(224)‧‧‧截流牆(225)‧‧‧處理槽(226)‧‧‧水生生物(227)‧‧‧過濾牆(228)‧‧‧排水閥(23)‧‧‧細過濾模組(234)‧‧‧儲水池(31)‧‧‧水質調整單元(32)‧‧‧水質測量器
