Embodiment Construction

[0019] The implementation of the present invention will be described below.

[0020] The construction of algae culture system:

[0021] 1 Use light-transmitting materials on the bracket, such as plastic film, to build a closed algae cultivation system to ensure a certain humidity.

[0022] 2 Install a carbon dioxide make-up system.

[0023] 3 Equipped with a gas regulating system to ensure the normal pressure of the entire closed system and the input of carbon dioxide along the way.

[0024] 4. The membrane plates are placed horizontally and fixed on the support. The distance between the membrane plates can ensure the light intensity required for the growth of algae.

[0025] 5 Culture solution spraying system. Membranes should be placed around the sprinkler system to maximize spray efficiency and ensure spray uniformity as much as possible.

[0026] The specific implementation includes the following steps:

[0027] 1. Vaccination. Inoculate the membrane plate with algae...

Abstract

The invention belongs to the field of microalgae culture and discloses a novel method for culturing microalgae. The novel method is characterized in that in an enclosed environment (1), a net having a certain area and a certain aperture size is used as an attachment (3) for growth of microalgae; multiple film plates are arranged horizontally from top to bottom; a distance is formed between every two adjacent film plates so that enough light is guaranteed; a culture solution is uniformly added on the film plates by a spraying system (4) and is used for microalgae growth; a carbon dioxide supply system (2) can supply enough carbon dioxide to the whole system so that normal microalgae photosynthesis can be guaranteed; and a gas adjustment system (5) guarantees normal system internal pressure and smooth supplement of carbon dioxide. Compared with the existing microalgae culture technology, the novel method has the advantages that microalgae can be separated and harvested easily; the problem of insufficient carbon dioxide supplement of the traditional culture mode is solved; water is saved; operation is simple; and a cost is low.

Description

technical field [0001] The invention belongs to the field of algae cultivation and relates to a new method for cultivating algae by using membrane plates. Background technique [0002] Climate warming is closely related to the concentration of carbon dioxide in the atmosphere. Due to the massive consumption of fossil energy such as coal, oil, and natural gas, the carbon dioxide released into the atmosphere exceeds the net fixed carbon dioxide capacity of the ecological environment, breaking the earth's carbon cycle process, causing climate anomalies, and affecting the living environment of human beings. [0003] Algae fix carbon dioxide and solar energy through photosynthesis, and finally form oils, proteins, polysaccharides and other active substances through a series of metabolism, which can be widely used in renewable energy, feed, food, medicine and health care, cosmetics and other fields. Algae has the advantages of high photosynthetic efficiency, fast growth, and shor...
