Embodiment

[0049] A method for large-scale semi-continuous cultivation of desert oil-producing microalgae, comprising the following steps:

[0050] 1) Runway pool construction and saline-alkali site selection

[0051] In the flat sandy land in the desert area, a glass greenhouse is established to control the temperature in the greenhouse at 15°C to 40°C, and a cement runway pool is built.

[0052] The concrete runway pool includes two 5.04m 2 The size of the runway pool is 4.8 (length) × 1.05 (width) × 0.5 (depth) m; one 200m 2 The runway pool is 40×5×0.5m in size.

[0053] The runway pool is made of cement material, and the construction is inclined (the bottom of the pool has a certain slope, 5.04m 2 meter runway pool with a drop of 5 cm; 200m 2 The runway pool has a drop of 5 cm), the cement pool wall is 0.3m above the ground, and tin foil is laid on the inner wall of the runway pool.

[0054] 2) Preparation of culture medium: The culture medium used in this example is based on th...

Abstract

The invention discloses a desert biodiesel producing microalgae large-scale semi-continuous culturing method. According to the desert biodiesel producing microalgae large-scale semi-continuous culturing method, culturing in small raceway ponds and large raceway ponds is realized, semi-continuous culturing in 200m<2> raceway ponds is realized via grade-by-grade (1 to 3 grades) amplified cultivation, and one batch of biodiesel producing microalgae can be harvested in 2 to 3 days. The desert biodiesel producing microalgae large-scale semi-continuous culturing method is capable of shortening culturing period obviously, and increasing efficiency; semi-continuous culturing grease yield in 200m<2> raceway ponds is as high as 5.43g/m<2>d; and grease yield is increased greatly. The desert biodiesel producing microalgae large-scale semi-continuous culturing method is especially suitable for desert areas, full utilization of desert idle lands can be realized; cost is reduced; and full utilization of resources is realized.

Description

technical field [0001] The invention belongs to the technical field of microalgae cultivation and production, and in particular relates to a method for large-scale semi-continuous cultivation of desert oil-producing microalgae. Background technique [0002] The first thing to develop biodiesel is not to compete with others for food or land. The desertification area in China is very large, and the natural conditions are harsh, the ecological environment is fragile, and the vegetation is sparse; however, the strong solar radiation and the large temperature difference between day and night are conducive to the accumulation of sugar and dry matter in plants. Cultivate microalgae without occupying arable land, and use light energy to consume CO 2 Its growth characteristics are very suitable for cultivation and utilization in China's desertification areas. Zhao Tao, Su Qing et al. (2011) reported that the production stage of microalgae consumes a large amount of CO 2 Compared w...
