| Abstract: | The geothermal wastewater in north China usually has high salinity,and contains ofharmful chemical elements,especially fluorine. The F content in the wastewater is around 7mg/L. The direct discharge of the wastewater is a source of environmental pollution. Use ofaquatic plants to purify the geothermal wastewater is an economical and effective method.The results of a pilot scale study indicated that aquatic plants,such as water hyacinth,phragmites communis,and typha orientalis, could grow in geothermal wastewater subjectedto pretreatment with lime precipitation technique and may absorb F,As,and Cd from thewastewater,The wastewater after purification can be used for irrigation purpose. |
