Algal forcing cultivation apparatus and cultivation method

摘要

Equipment and method for forcing cultivation by controlling the environment most suitable for algae growth in an artificial environment of dissolved gas, light, temperature, nutrient source, and sanitary environment. The apparatus of the present invention includes a water tank (1) for cultivating algal algal bodies as seedlings, a gas dissolution and diffusion apparatus (3-a, 3-b) for dissolving gas in the culture water in the water tank, and the wavelength and illuminance. Includes a light irradiation device (10, 11) for irradiating the aquarium with controlled light, a temperature control device (20) for controlling the temperature of the culture water in the aquarium to a certain range, and an essential nutrient source essential for algae growth The apparatus includes a nutrient salt addition device (17) for adding nutrient solution to the water tank, a purification device (12) for performing sterilization filtration of the culture water in the water tank, and a control measuring device for each device.
