摘要
水污染是目前面临的一类主要的环境问题之一,利用水生高等植物治理污染水体的方法正逐渐受到人们的关注。菖蒲属植物在我国各地均有分布,该属的菖蒲和石菖蒲已被广泛运用于污染水体的治理。综述了菖蒲属植物净化污染水体的主要功能及研究进展。菖蒲属植物对富营养化水体中的TP、TN、NH3-N等指标具有显著的去除效果,对富营养化水体中藻类生长有显著的抑制效果。同时,对Cu、Pb、Cr、Zn等多种重金属的吸收富集效果明显,对萘、芴、蒽、芘等有机污染物具有一定的吸收效果。此外,菖蒲与茭白、酸模、鸢尾等组合使用可提高污水净化效率。说明,菖蒲属植物可作为治理水体污染的重要物种,对治理污水具有较好的技术经济价值。
Water pollution is one of the major environmental issues, higher plants for purifying sewage attract many researchers. Acorus are widely distributed in China. A. calamus and A. tatarinowii has been widely applied in polluted water management. The authors summarized the applications of Acorus in water pollution control. It shows that Acorus has obvious effect in absorbing TN, TP, NH3-N in eutrophic water and has a significant restraint effect on the growth of algae It also has obvious effect in absorbing heavy metals such as Cu, Pb, Cr, Zn and and has certain removal effect about organic pollutants such as naphthalene, anthracene, pyrene and AAF. In addition,The combination of Acorus, Wildrice, Rumea＂ and Iris can improve sewage purifying efficiency. So Acorus is one of the most important species in water pollution control, Using Acorus for purifying polluted water has better technical and economic value.
