[Recent progress in treatment of aquaculture wastewater based on microalgae--a review].

Microalgae enables aquaculture wastewater recycling through a biological conversion. Recently, many studies have been reported on microalgae cultivation and wastewater treatment, including developing various wastewater treatment technologies such as algae pond, activated algae, immobilized algae and algae photo-bioreactor. In this review, we address the mechanisms, progress and application in the purification of aquaculture wastewater, as well as some research perspectives.
