This paper describevS the performance of artificial wetland wastewater treatment system (AWWTS) using cattail (Typha augustifolia), rush (Jutuus effusus) for upgrading municipal and artificial wastewater. the growth state of cattail and rush have heea investigated. The mean water quality of effluent from upgrading municipal wastewater by wetland, equivallent to 5 and ID categoriea from the National Ground water Environmental Quality Criterion. In rush artificial wetland, removal effeciencies of KN、NH₄⁺-N. TP and COD_Cr are more than 94%. NH₄⁺-N is the range of 82.2%-97.7% from artificial wastewater; under ordinary condition, more than 96% KN and NH₄⁺-N are removed in summer by cattails. but the removal effeciencv in winter is lower tban other seasons (P<0.05), the removal effeciencies of TP and CODCr are steadily and above 94% (only one time 85.8%). Cattails leaver are fallen in winter and under high loading COD_Cr (1 000mg/L) wastewater, but rushes can grow vigorously all the time. Therefore, cattail and rush are suitable macrophytes to artificial wetland wastewater treatment system in Wuhan and they are broad distributed in the regions around 30°N. especially rush is better for growing vigorously in winter.
