摘要/Abstract

摘要： 土地利用是资源化利用城市污水厂污泥的有效途径.为了解污泥中重金属污染物在土壤、植物之间的迁移富集规律,选用8种园林用植物进行污泥混配土种植实验.结果表明,植物对污泥混配土土壤中铅的富集能力,以及铅在植物中各器官的富集系数均不同,且不同种类植物差别较大.植物根部对铅有较强的富集能力,其次是叶和茎.菊花对铅的富集能力较强.植物对土壤中铅的富集能力也受土壤铅含量和赋存形态影响.

关键词: 污染土壤, 修复标准, 方法体系, 生态风险评价

Abstract: Heavy metals can be accumulated in soil due to the application of sewage sludge on land over years.It will cause environmental safety problems if heavy metals accumulated in soil.Eight species of garden plants were planted in the substrate mixed by sewage sludge and beach soil to study how lead was enriched and transferred in plant-soil system.The results showed that the enrichment ability of plants was different,among which chrysanthemum was the most effective in lead enrichrnent.Lead absorbed by plants was not equally distributed in different parts of the plants,and the root absorbed more than other organs.The enrichment ability of plants was related with the concentration and form of lead in soil.

Key words: Contaminated soil, Remediation standard, Methodology, Ecological risk assessment
