To provide a method and device for cultivating algae that can cultivate algae by utilizing the exhaust heat generated by a ship's engine, does not require a large workspace in the ship, and cultivates algae at low cost without deploying personnel for algae cultivation on the ship.SOLUTION: An algae culture device 1 is a device for carrying out a sowing or planting process and a harvesting process of algae on land, and a cultivation process on board a ship F1, comprising: a mixing tank 3 that prepares culture water by mixing seawater and warm wastewater obtained by heating the seawater with the heat of an engine F2 of the ship F1; a culture tank 4 that supplies culture water and air and further cultivates algae by irradiating it with light; a wastewater sterilization unit 9 that sterilizes the culture wastewater discharged from the culture tank 4 by mixing sterilizing water containing sodium hypochlorite; and a control unit 2 that automatically controls a temperature of the culture water in the culture tank 4, an irradiation time of the light irradiated on the algae, and an amount of sterilizing water mixed into the culture wastewater in the wastewater sterilization unit 9.SELECTED DRAWING: Figure 1
【課題】船舶のエンジンから生ずる排熱を利用して藻類を培養することができ、船舶内に広い作業場所を用意する必要がなく、藻類培養のための人員を船舶に配置せずに低コストで藻類を培養する、藻類の培養方法及び装置を提供する。【解決手段】藻類培養装置1は、藻類の播種又は植付の過程と収穫過程とを陸地で行い、育成過程を船舶F1内で行うための装置であり、海水と海水が船舶F1のエンジンF2の熱によって昇温されて得られた温排水を混合して培養水を調製する混合水槽3と、培養水と空気を供給し、さらに光を照射することで藻類を培養する培養水槽4と、培養水槽4から排出される培養排水に次亜塩素酸ナトリウムを含有する殺菌用水を混合して殺菌する排水殺菌部9と、培養水槽4内の培養水の温度と藻類に照射する光の照射時間と、排水殺菌部9における培養排水への殺菌用水の混合量を自動的に制御する制御部2を備える。【選択図】図1
