Abstract

The invention discloses a chlorella which belongs to the technical field of producing biodiesel and a cultivating method thereof. The chlorella is named as Chlorella YJ1, and the registration number of the spawn preservation is CGMCC No. 3037. The invention also discloses the application of the chlorella in producing biodiesel. Second-grade effluent water of municipal sewage is taken as the culture medium to grow the chlorella without adding nutrient elements such as nitrogen, phosphorus and the like, thus reducing the cost of producing biodiesel and lightening the burden of water resource. The chlorella is used for establishing the process of municipal sewage deep treatment, and the biodiesel can be obtained at the same time of the sewage treatment, which is a sewage recycling and biodiesel producing technology with eco-friendliness and low cost.

Description

technical field

[0001] The invention belongs to the technical field of biodiesel production, and in particular relates to a chlorella and its cultivation method and its application in biodiesel production. Background technique

[0002] Fossil energy is facing the plight of depletion, and it is imperative to find sustainable renewable and environmentally friendly new energy sources. Microalgae has the characteristics of fast growth rate, short harvest period, and high photosynthetic utilization rate. The use of microalgae as a raw material for biodiesel has attracted more and more attention. At present, most of the existing microalgae used as raw materials for biodiesel are separated in seawater, and are mainly cultivated in medium with high nutrient concentration, and the production cost is too high. Therefore, it is necessary to combine the production of biodiesel with the production of other by-products (such as animal feed, fertilizer, etc.) or service behavior (use of w...
