The present invention relates to the technical field of microbiological devices, and in particular to an integrated device and method for microalgae cultivation, harvesting and oil preparation. Wastewater to be treated and an appropriate amount of microalgae cells are sequentially added from an injection port into a microalgae cultivation main chamber, and then the temperature, light, and stirring speed parameters are set according to predefined optimal culture conditions to start microalgae cultivation and wastewater treatment. The present invention realizes efficient and clean treatment of various types of wastewater, especially seaweed processing wastewater, and rapid harvesting of microalgae cells. The obtained biomass can be further used for the extraction of high-value active substances such as bio-oil and the development of microalgae biological products, thereby generating considerable economic benefits. In addition, by integrating the treatment of wastewater, the harvesting of highly economical microalgae, and the preparation of active substances, rapid separation of microalgae cells from culture fluid and efficient preparation of oil are realized, thereby effectively simplifying the harvesting process of large-scale microalgae cultivation and significantly reducing the harvesting cost.
