城市重金属污染水体的植物修复试验研究

针对城市重金属污染水体治理困难的现状,分析了湿地植物在重金属污染水质中的修复作用,通过开展试验将不同的湿地植物对重金属污染水体的修复作用进行了对比研究,并对不同pH值对湿地植物去除重金属离子效果进行了试验研究。试验结果表明,湿地植物芦苇对重金属污染的水体修复效果明显,能够有效的滤除水体中的重金属例子;最后对水生植物对重金属污水的修复机理进行了试验研究,对于进一步推动和发展湿地植物干预治理城市重金属污染水环境具有一定的借鉴意义。

Experimental Research on Plants Repairing to City Water Resource Polluted by Heavy Metal

For urban heavy metal pollution status of water treatment difficulties,the repair function of plants to heavy metal polluted water was analysed. The repair function of different wetland plants to heavy metal polluted water compared by experiment and the phytoremediation effect of wetland plant to adsorb heavy metal icons under different pH surroundings were researched. The results showed that reed had the best repair function to heavy metal polluted water,and it could adsorb much more heavy metal in the pol...
