Abstract

Abstract

Reclaimed water could be achieved through advanced wastewater purification technology using constructed wetlands. Water reclamation by constructed wetlands can effectively alleviate the shortage of water resources and address both pollution reduction and carbon reduction needs. However, insufficient carbon/oxygen supplement leads to a low pollutant removal rate and low resource transformation rate, limits the scale-up application of constructed wetlands. Microalgae-based wastewater treatment offers several advantages, including photosynthetic oxygen release, carbon fixation, and efficient resource recovery of pollutants, which has high complementarity with constructed wetlands. This paper thoroughly compared the performance of two coupling modes of microalgae and constructed wetlands in the aspects of carbon/oxygen regulation of water purification mechanism, pollutant removal and resource transformation. The water purification process of the coupled system was analyzed from the perspective of carbon, nitrogen and phosphorus transformation, and the optimal path of adding moderate microalgae biomass in the anoxic area of constructed wetland was proposed. Finally, the paper outlined the future research in this field, focusing on system purification mechanisms and operation efficiency.
