高盐废水处理中耐盐湿地植物的筛选

Research Progress on Screening of Salt-tolerant Wetland Plants in High Salinity Wastewater Treatment

目前利用人工湿地工艺去除高盐废水中的污染物被认为是非常有前景的污水净化技术之一。本文从湿地植物净化高盐废水的作用和机理入手,分析了盐胁迫对湿地植物的形态上和生理上的影响,列出了多种湿地植物的耐盐阈值及对污染物的净化效果,并对利用湿地植物去除高盐废水中污染物的研究工作进行了展望,旨在为筛选湿地植物去除高盐废水中的污染物提供技术参考。

At present, the use of constructed wetland process to remove pollutants from high salinity wastewater is considered to be one of the most promising sewage purification technologies. In this paper, starting with the function and mechanism of wetland plants in purifying high salinity wastewater, the morphological and physiological effects of salt stress on wetland plants were analyzed, and the salt tolerance thresholds of many kinds of wetland plants and their purification effects on pollutants were listed. The research work of using wetland plants to remove pollutants from high salinity wastewater was prospected, in order to provide technical reference for screening wetland plants to remove pollutants from high salinity wastewater.
