污泥耐受性草本植物的筛选及其对重金属Cu、Zn的富集
Selection of herbaceous plants to sludge tolerance and their enrichment properties to heavy metals(copper and zinc)
摘要
Abstract
In order to detect the feasibilitiey of phytoremediation of the sludge, the medium soil with different sludge proportion were made. The sludge tolerance of 19 herbaceous plants which were collected from Henan, Yunnan and Shanghai were investigated by pot experiment. The growth responses of plants to sludge were determined, and heavy metals Cu and Zn contents were also tested. Results showed that the medium soil with the sludge proportion less than 60% could be used as agricultural soil. Bidens pilosa Linn, Echinochloa crusgalli Beauv, Schizonepeta tenuifolia Briq and Kalimeris indica (Linn. ) Sch had strong patience and resistance to heavy metals in sludge. Bidens pilosa Linn had good remediation potential to Cu and Zn contaminated soil. Echinochloa crusgalli Beauv could be used as the phytostabilisation plant in Zn contaminated soil. Kalimeris indica ( Linn. ) Sch had stronger remediability of Cu and Zn contaminated soil.关键词
