摘要: 为研究浮水植物对水环境中重金属的移除能力和特性，按照污水综合排放标准限量浓度的1倍、2倍、5倍和10倍分别设置4个暴露水平，对凤眼莲、圆心萍、肚兜萍、小浮萍、大浮萍、大薸和柳叶空心菜7种浮水植物去除水体环境中重金属的能力进行了比较分析，并确定凤眼莲、大薸和肚兜萍（质量比为1：1：1）混合植株对重金属的去除效果最佳。结果表明，暴露水平为污水综合排放标准限量浓度的2倍时，混合植株对镉、铜、锌、铬和镍5种重金属的累积去除率达到最高，分别为75.86%、82.97%、72.19%、80.06%和75.92%；暴露水平为污水综合排放标准限量浓度的5倍时，混合植株对铅的累积去除率达到最高，为76.01%。本研究所确定的混合植株对水环境中重金属的累积去除效应明显，可以为水环境中重金属污染的修复、淡水养殖水产品过程中的重金属防控以及提升水产品的质量安全提供基础数据和技术支持。Abstract: The ability and characteristics of floating plants to remove heavy metals in water environment was investigated in this study. Four exposure levels were set in accordance with the concentration of one, two, five and ten times of the limit concentration of the comprehensive sewage discharge standard. The ability of seven kinds of floating plants, including Eichhornia crassipes, Limnobium laevigatum, Salvinia natans, Spirodela polyrrhiza, Pistia stratiotes L., Pistia stratiotes and Ipomoea aquatica Forsk, to remove heavy metals in the water environment has been compared and analyzed. It was determined that the mixed plants of Eichhornia crassipes, Pistia stratiotes and Salvinia natans (mass ratio:1:1:1) had the best removal effect on heavy metals. The results showed that the cumulative removal rates of Cd, Cu, Zn, Cr and Ni were the highest when the exposure level was twice the limit concentration of the comprehensive sewage discharge standard, which were 75.86%, 82.97%, 72.19%, 80.06% and 75.92%, respectively. And when the exposure level was five times of the limit concentration of the comprehensive sewage discharge standard, the cumulative removal rate of Pb by the mixed plant was the highest, which was 76.01%. The mixed plants identified in this study have obvious cumulative removal effects on heavy metals in the water environment. This can provide basic data and technical support for the restoration of heavy metal pollution in the water environment, the prevention and control of heavy metals in the process of freshwater aquaculture aquatic products, and the improvement of the quality and safety of aquatic products.
