Abstract

The invention provides a system for culturing oleaginous micro-algae by combining a light guide pipe and a raceway pond, and belongs to the technical field of sewage treatment. The system comprises a raceway pond body and a light guide pipe, the raceway pond body is provided with an online water quality monitoring analysis meter, a water pump, a water inlet and a water outlet, the light guide pipe is mounted on a pond top cover of a small raceway pond device of a steel frame, natural light is captured and redistributed by the light guide pipe, micro-algae at different depths in the pond is irradiated by the same light intensity, so that growth and reproduction of the micro-algae in the raceway pond are facilitated, and the system has an important practical values to research progress of mass and high-density culture mode of micro-algae and industrialization of micro-algae biodiesel.

Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, and relates to a system for cultivating oil-producing microalgae in combination with a light pipe and a raceway pool. Background technique

[0002] Energy is the foundation of the development of modern society and is related to national security and economic security. my country is rich in coal, poor in oil, and low in gas. Since the rapid economic development, China's energy demand has increased sharply. In 1993, 2006, and 2009, China became a net importer of oil, natural gas, and coal respectively. At present, although my country's economic growth rate is slowing down, it is still on the rise, and the dependence on fossil fuels is still higher than 50%. The energy problem has become a bottleneck restricting my country's economic development.

[0003] The shortage of energy has prompted countries to look for new clean energy. Since 2005, global solar power and wind power have grown ra...
