Device for culturing algae at constant temperature and experimental method

Abstract

The invention discloses a device for culturing algae at constant temperature and an experimental method, the device comprises a water tank, a transparent culture cylinder, water inlet and outlet equipment, a heating, lighting and air supply structure and the like, and the experimental method comprises the steps 1-5. The culture device designed by the invention adopts a water bath temperature control design concept, and has the advantages of controllable temperature, stable heating and uniform algae heating; according to the transparent culture cylinder and the mounting structure thereof, entering of air pollution particles can be reduced; water used by the heat preservation layer can be recycled by water in the water pool; the main control box is adopted to control the illumination intensity, and the timing device is adopted to control the lamp tube to control the illumination time to achieve the optimal growth condition; by using the design concept of water bath temperature control, the device has the advantages of controllable temperature, stable heating and uniform heating of algae, and redundant water is discharged by the drainage pipeline above the acrylic plate column and enters the water pool again to realize water recycling.

Description

technical field [0001] The invention relates to the technical field of algae cultivation, in particular to a device and an experimental method for culturing algae at a constant temperature. Background technique [0002] Microalgae is a single-celled organism with a high oil content, especially Chlorella, the oil content can reach 20% of the dry cell weight, a variety of nutrients, can be used to prepare biodiesel, can be taken as a nutritional supplement, and Chlorella has the functions of anti-aging and beauty. Scenedesmus is rich in protein and vitamins, and is a good feed for fish. If you use organic sewage to oxidize fish, you can get high yield. The proliferating algae can also be used as feed for poultry. At the same time, microalgae have broad application prospects in feed, food, medicine and cosmetics. The basis of these applications is the large-scale cultivation of microalgae. [0003] During the cultivation process of algae, the growth and reproduction speed fl...

Problems solved by technology

This culture method uses pipelines and relies on power to make the culture fluid flow and introduce carbon dioxide-containing air, but the equipment is complicated

Biological contamination, such as bacterial growth, is prone to occur in open culture cultures

[0005] At present, most of the devices for cultivating algae adopt the method of incubator cultivation. The incubator is a closed and opaque structure, which is not suitable for directly observing the growth of algae. It is also necessary to replace the air pump regularly to maintain sufficient carbon sources inside the algae. At the same time, the incubator The medium temperature cannot be directly observed, and the temperature conditions are difficult to control, resulting in the failure of algae cultivation. Therefore, a cultivation device with controllable temperature, simple equipment and low energy consumption is needed
