Abstract:

Microalgae, as the third generation biomass energy, has great potential in wastewater treatment. In order to seek more economical treatment methods, the co-culture of microalgae with other microorganisms can promote the flocculation harvest of microalgae and increase biomass and lipid production, thus reducing the cost of microalgae wastewater treatment. In this paper, the types of microalgae co-culture systems and the mechanisms, system settings, and influencing factors of microalgae co-culture treatment of wastewater were summarized. The current research of microalgae using wastewater as a growth substrate to produce high-value by-products was described, and the prospects and challenges of wastewater treatment and reutilization by microalgal co-culture were pointed out.

Key words: microalgae, co-culture, wastewater treatment, resource utilization, biodiesel
