1. A microalgae culturing pond constructed wetland coupled system for advanced sewage purification, comprising:
a microalgae culturing pond and a constructed wetland connected in series;
a microalgae capturing filler arranged in the microalgae culturing pond, the microalgae capturing filler configured to recover more than 80% of the microalgae from the microalgae culturing pond;
a flow channel connecting the microalgae culturing pond and the constructed wetland, the flow channel configured to introduce algae-containing water, obtained after the microalgae capturing filler captures microalgae, into the constructed wetland; and
a flow guide pipe configured to direct a portion of the microalgae recovered into an anoxic denitrification area below liquid surface in the constructed wetland.
