Problems solved by technology

[0002] According to general algae culture, carbon dioxide is provided by directly feeding air, or the waste gas discharged from thermal power plants is fed into the cultivation tank. Using air as a source of carbon dioxide is cheap and not limited by the location, but in the air The low carbon dioxide content cannot provide enough carbon sources to support the growth of high-concentration algae. The exhaust gas from thermal power plants contains high concentrations of carbon dioxide. However, this method can only be used to cultivate algae at locations around thermal power plants. Not suitable for most cultivation farms without power plant exhaust gas supply
[0003] The above-mentioned commonly used technology changes the concentration of carbon dioxide required for algae cultivation, which will affect the content of oil produced by algae

Embodiment Construction

[0020] The integrated algae biodiesel and algae fermentation and reuse method of the present invention include microalgae 1, photoreactor 2, oil extraction 3, fermentation tank 4, by-product 5, etc.; wherein:

[0021] Microalgae 1 is an algae that is selected to be cultured and can produce high-concentration oil.

[0022] The photoreactor 2 is a device for cultivating microalgae 1. The light of the algae can be controlled by the use of the photoreactor 2. After sampling every 24 hours, the absorbance value, carbon source supply, and carbon It accounts for 40%-50% of the dry weight of microalgae. If carbon dioxide is used as a carbon source, about 1.5-2.0KG of carbon dioxide is needed for growth to produce 1KG of cells. Higher carbon dioxide ventilation can increase the oil content of algae , temperature, rising temperature will lead to a decrease in the solubility of carbon dioxide, affecting photosynthesis and resulting in poor growth, and the oil content will also decrease w...

Abstract

The invention provides integrated type algal biodiesel and a frond fermentation recycling method. The method comprises the steps of photoreaction of microalgae, grease extraction, fermentation, by-product production, and the like. The method is characterized in that oxygen generated by microalgae growth is supplies to the fermentation of a frond; conversely, carbon dioxide generated by frond fermentation is supplied to a carbon dioxide source needed by microalgae growth so that the running of a photoreactor and a fermentation tank form a circulating state.

Description

technical field [0001] The invention belongs to the fields of bioengineering and clean energy, and in particular relates to the fields of algae biodiesel and algae body fermentation and reuse. Background technique [0002] By the way, it is customary to supply carbon dioxide directly through the air when cultivating general algae, or pass the waste gas from the thermal power plant into the cultivation tank. Using air as the source of carbon dioxide is cheap and not limited by the location, but in the air The content of carbon dioxide is low and cannot provide enough carbon source to support the growth of high-concentration algae. The exhaust gas from thermal power plants contains high concentrations of carbon dioxide, but only the locations around thermal power plants can use this method to cultivate algae. It is not suitable for most cultivation farms without power plant exhaust gas supply. [0003] The above-mentioned commonly used technology changes the concentration of ...
