Comparative study of wastewaer purification efficiencies of two emergent helophytes: typha latifolia and juncus subulatus under arid climate

摘要

The aim of he present stuidy is to assess wastewater purification efficiency of two higher aquatic plant, Typha latifolia and Juncus subulatus in an arid climate. The experiemtn was conducted from August 1994 to March 1996. The plots (capacity: 115 liters, diameter: 57 cm) were filled to 5 cm depth with gravel and 30 cm with soil (texture: 30
