Abstract

Anaerobically digested swine wastewater was treated by a novel constructed wetland.

Tidal operation was better for total nitrogen removal than intermittent flow.

Mechanism of nitrogen removal by biozeolite-based constructed wetland was discussed.

Simultaneous nitrification and denitrification were determined in zeolite layer.
