浙江某金属制品厂地块受到重金属、多环芳烃等复合污染。根据复合污染物互相作用的特性及现场实际情况,采用陶粒窑协同处置和异位化学氧化联用技术对污染土修复施工,更高效、环保地去除污染物,达到预期的修复目标和修复效果,实现了修复后土壤的资源化利用。该修复工程实例的研究为其他复合污染场地修复工程提供了宝贵经验和技术支撑。

A metal products factory site in Zhejiang province,China is polluted jointly by heavy metals and polycyclic aromatic hydrocarbons.According to the interactions among co-pollutants and the actual situation at the site,ceramsite kiln and ex-situ chemical oxidization technologies are combined to remediate the polluted soil,which removes contaminants more efficiently and environmentally.The expected remediation target and effect have been achieved,and the remediated soil can be reused.The study on the remediation engineering case can provide valuable experience and technical support for other co-contaminated sites.
