Recent progress in coupling technologies of biogas slurry treatment based on microalgae cultivation

Recently, more attentions have been paid to the coupling technologies of biogas slurry treatment based on microalgae cultivation in the field of utilization of biogas slurry. In this paper, both recent progress and future direction of the coupling technologies were summarized. Then, the key areas of the development of coupling technology were also pointed out, such as the high CO₂ tolerance algae breeding and study on the mechanism of carbon sequestration in coupling technology of biogas slurry treatment and CO₂ fixation, low cost and low energy consumption technology development of high-quality biomass production in coupling technology of biogas slurry treatment and high-quality biomass production, systematic evaluation system lacking in coupling technology of biogas slurry treatment and ecological agriculture. Finally, the prospects were reviewed from four points to promote coupling technologies to break through the existing bottlenecks, which are microalgae breeding, microalgae cultivation, biogas slurry treatment, and comprehensive economy of biogas engineering.
