Effectiveness of cyclic treatment of municipal wastewater by - Loofah biofilm, its internal community changes and potential for resource utilization.

Microalgae biofilm has garnered significant attention from researchers in the field of sewage treatment due to its advantages such as ease of collection and stable sewage treatment capabilities. Using agricultural waste as biofilm carriers has become a hotspot in reducing costs for this method. This study first combined with loofah to form a microalgae biofilm for the study of periodic nitrogen and phosphorus removal from municipal wastewater.
