摘要

基于对植物修复空间特异性的理解，针对联通关中水系的涝池近年来出现的水体富营养化和黑臭现象，选取常见浮床植物美人蕉、水菖蒲和西伯利亚鸢尾，通过室外水培试验，探究其对涝池污染原水的净化效果，试验共持续35天。结果表明：（1）试验结束时，3种植物在株高、根长生物量均有显著增加，增长率表现为美人蕉 > 水菖蒲 > 西伯利亚鸢尾。（2）美人蕉、水菖蒲和西伯利亚鸢尾对水体中TN的平均去除率分别为56.18%，52.17%，60.76%，均显著高于对照组（P<0.05）；美人蕉和水菖蒲对水体中TP平均去除率分别为55.42%和58.32%，均显著高于对照组（P<0.05），而西伯利亚鸢尾组与对照组无显著差异（P>0.05），此外美人蕉和水菖蒲还能起到调节水体pH和DO的作用。（3）3种植物对水体中NH3—N的平均去除率分别为76.98%，65.71%，78.94%，其中美人蕉组和水菖蒲组NH3—N的主要去除途径为植物吸收和硝化反应，西伯利亚鸢尾组NH3—N的主要去除途径主要是氨的挥发和硝化反应等，而对照组NH3—N去除率高达60.55%的主要原因是氨的挥发；植物组及对照组中NO3-—N浓度随时间均呈现增加趋势，主要与各试验组中水体硝化反应及植物吸收效率的差异性有关。（4）3种植物中，水菖蒲适用于点源和面源2种污染源涝池水体的净化，美人蕉只适合用于面源污染涝池水体的净化，而西伯利亚鸢尾净化能力较差，生长适应性差，不适宜作为水生浮床植物推广。研究结果为涝池污染水体修复的浮床植物选择提供参考。

Abstract

Based on the understanding of the spatial specificity of phytoremediation

aiming at the phenomena of eutrophication and black odor in water storage pond which is an important component of connecting the water system in Guanzhong area in recent years

three common floating-bed plants (canna

calamus

and Siberian iris) were selected to explore their purification effect for the raw water in the water storage pond by outdoor hydroponics test. The test lasted 35 days. The results showed that: (1) At the end of the experiment

the height and root length biomass of the three plants increased significantly

and the growth rate was as follows: canna > calamus > Siberian iris. (2) The average removal rates of TN in water bodies were 56.18%

52.17%

and 60.76%

respectively

which were higher than that of the control group (P<0.05). The average removal rates of TP in water bodies of canna and calamus were 55.42% and 58.32%

which were higher than the control group of 15.57% (P<0.05)

but the Siberian iris group was not significantly different from the control group (P>0.05). In addition

canna and calamus could also adjust and improve pH and DO in the water. (3) The average removal rates of NH3—N in water were 76.98%

65.71%

and 78.94%

respectively. The main removal pathways of NH3—N in the canna and calamus were plant uptake and nitrification. The main removal route of NH3—N in the Siberian iris group was mainly ammonia volatilization and nitrification

while the removal rate of NH3—N in the control group was 60.55%

of which main removal reason was ammonia volatilization. The concentration of NO3-—N of plant group and control group increased with time

which was mainly related to the difference of water nitrification reaction and plant absorption efficiency in each experimental group. (4) Among the 3 floating-bed plants

calamus was suitable for the purification of the water of the point source pollution and non-point source pollution. The canna was only suitable for the purification of the water of non-point source

while the Siberian iris had poor purification ability and growth adaptation in both

which was not suitable for promotion as an aquatic floating-bed plant. The research results provide a reference for the selection of floating-bed plants for the restoration of polluted water bodies in water storage pond.
