Abstract

Disclosed herein is a carbon supply device for supplying carbon dioxide during large scale cultivation of micro-algae in open pond, and its application method and use. The device comprises a trap container in which a partition plate is installed vertically and has a 10-50 cm gap from the container bottom, and the partition plate is higher than the wall of the trap container; and a gas distributor is positioned at the bottom of the container. In use, the trap carbon supply device is embedded in bottom of an open pond, wherein the partition plate is above the liquid level of the culture solution in the open pond such that the culture solution driven by a stirrer flows into the trap carbon supply device from one side thereof, and flows out of the device from the other side thereof, wherein the culture solution is mixed with carbon dioxide at the bottom of the container.
