Method of re-improvement algae growth includes several processes like alkali solution preparation, cultivation tank preparation, cultivation tank detector, PH value adjustment.The alkali solution absorbs carbon dioxide of atmosphere to produce carbon dioxide solution that contains abundant of carbonate and is one of nutrient sources of algae.There is a detector in cultivation tank.When algae is in stunted growth condition like concentrate of nutrient sources falls, PH value rises, and so on, the carbon dioxide solution will be injected into cultivation tank, and thus is effective to re-stimulate algae growth to achieve rapid growth.本發明係有關一種再度提升藻類生長之方法,主要包含鹼水製備、培養槽製備、偵測培養槽與調節PH值等步驟,該係藉由鹼性水溶液來吸收大氣中二氧化碳以製成富含碳酸根之二氧化碳水溶液,該二氧化碳水溶液可用來當作藻類之營養源,透過對培養槽內偵測,在營養源濃度下降或PH值上升等使藻類進入生長疲乏的狀況下,將二氧化碳水溶液饋入培養槽中,藉此,可有效再次刺激藻類生長,以讓藻類達到快速成長之效果。1...鹼水製備2...培養槽製備3...偵測培養槽4...調節PH值
