The invention belongs to the technical field of water treatment and discloses a composite artificial wetland system for wastewater treatment, which comprises: a filtering module to primarily filter impurities in wastewater through a mechanical grille tank; a wastewater treatment module to purify, precipitate and degrade wastewater through a plurality of wastewater treatment tanks; an artificial wetland module to purify harmful matters in the treated wastewater through purifying plants; a water storage module to collect and store treated water through a water storage tank. The system herein with a primary vertical-flow artificial wetland and a secondary vertical-flow artificial wetland can fully purify and filter the harmful matters in the wastewater, can effectively treat fluorine-bearingwastewater, silicon-bearing wastewater, cyanogen-bearing wastewater and oil refining wastewater, and helps greatly decrease pollutant emission and recycle the wastewater, thereby reducing water consumption and emission discha
