Abstract

The invention discloses a ring-type photobioreactor for microalgae culture, including a lidless container and a bottom plate, wherein the lidless container and the bottom plate are connected by a vertical mirror housing to form a cavity; the upper portion of the inn side of the cavity is provided with a gas pipe; an air charging port is arranged on the gas pipeline, a column photobioreactor is uniformly arranged along the inner ring of the gas pipeline, the column photobioreactor is connected with the gas pipeline, and a liquid flow channel is formed between the column photobioreactors throughthe connection of the liquid pipelines arranged at the lower part of the column photobioreactor; a lamp post is arranged at the central position of the cavity, the column photobioreactor comprises aglass tube and a wall-attached culture plate arranged on a glass fiber cloth, wherein the glass fiber cloth is suspended in the glass tube, and algal cells are inoculated on the wall-attached cultureplate, thereby providing a photobioreactor with the advantages of simple structure, space saving, high light utilization efficiency and high yield.

Description

technical field [0001] The invention belongs to the technical field of microalgae cultivation, in particular to a circular photobioreactor for microalgae cultivation. Background technique [0002] Microalgae are a class of single-celled algal organisms that are widely distributed in freshwater or brackish water. It has a strong photosynthetic ability and rapid reproductive ability. During the growth process, it absorbs carbon dioxide, nitrogen and phosphorus in the water body, and at the same time accumulates oil, pigment, protein and other useful substances in the cells. Therefore, microalgae have the value of carbon sequestration, wastewater treatment, bioenergy production, and high value-added products. In the case of increasingly tight fossil fuels and increasingly low-carbon requirements, the research on large-scale cultivation of microalgae using algae as a raw material for bioenergy will generate huge social benefits. At present, the large-scale photoautotrophic cul...
