The matrix composition recipe for sewage treating artificial wet land includes basic matrixes for all kinds of water quality and optional matrixes for special water quality. The basic matrixes are mixed sand and soil and crushed stone; and the optional matrixes include zeolite, limestone, coal slag, steel slag, furnace slag, crushed stone, haydite, melon seed piece and pebble. The total height of the basic matrixes and the optional matrixes is 0.6-1.2 m. The present invention determines the matrix composition recipe of sewage treating artificial wet land according to the characteristic pollutant in the sewage to be treated and has raised sewage treating efficiency of artificial wet land, no jamming, reduced covered land area and low cost.
