| Outline of Final Research Achievements |
Resource/energy recovery from wastewater is crucial for sustainable development of wastewater treatment plants (WWTPs). In this project, we achieved fruitful results on the following six aspects: (1) Rapid granulation and harvesting of natural microalgae and single cell microalgae; (2)Value-added biomaterials accumulation and production from wastewater, including phosphorus, alginate-like exopolymers (ALE), proteins, polysaccharides, and lipids; (3) Impacts of operation mode on the system stability and nutrients removal; (4) Granular system stability and remediation under various conditions; (5) Heavy metal (with Cr as example) recovery from wastewater and safe posttreatment of heavy metal-loaded granules; and (6) Deep insight into the biogranulation of bacteria/microalgae symbiosis and microalgae, highlighting the functions of specific microalgae species and extracellular polymeric substances (EPS).

| Academic Significance and Societal Importance of the Research Achievements |
During 2018-2022, we published 37 articles in the top 10 jourals in the field of Environmental Engineering, and shared 36 presentations (5 invited keynotes) with peers in international conferences. The results definitely lay a solid foundation for the sustainable management of wastewater industry.
