摘要
纺织工业生产运行会产生大量的有色废水。数以百万吨计的废水最终流入河流,对人类的生存造成了严重的危害。废水中含有大量的重金属、氮、磷化合物等,同时增加了化学需氧量(COD)、生物需氧量(BOD)、残渣总量(TS)。所以对废水进行净化处理十分必要。植物修复技术在处理废水上具有高效且低成本的特性,采用湿地植物的基于水生大型植物处理系统(AMATS)是其有效方案。由于价格低廉和易于生长,最常用的湿地植物有水葫芦、水浮莲、浮萍等。现调研了近年来的相关研究,对这些植物的特性和净水机制进行了综述。
Textile industry produce a large number of highly colored wastewater.These millions tons of wastewater eventually flow into the river,which does harm to the survival of mankind seriously.Wastewater contains large amounts of heavy metals,nitrogen and phosphorus compounds,while increasing the chemical oxygen demand（COD）,biological oxygen demand（BOD）,and total solids（TS）.Therefore,the purification treatment of wastewater is necessary.Phytoremediation is highly efficient and cheap on the treatment of wastewater.It has a specific solution called aquatic macrophytes plant treatment systems（AMATS）,using wetland plants as environmental protective technique.It is widespread to utilize wetland plants such as water hyacinth,water lettuce and duck weed,because of low cost and easy operability.This paper investigated the recent research,and reviewed the characteristics and mechanisms of plants on wastewater treatment.
