随着我国城市化进程的发展，城镇建设过程中面临越来越多的旧工业场地修复问题，在建设渭东新城项目的过程中，发现项目存在废弃化工场地等污损土地，在可能存在污染的地点进行采样，发现废弃化工厂处、生活污水排水口存在Hg、Pb、As超标现象，本文在渭东新城土壤重金属调查的基础上，综合了国外对于土壤污染治理的治理方略及发展进展，进行Hydrus模拟，预测重金属Pb在未经处理情况下，未来30a的迁移过程，以期为类似于渭东新城的重金属超标场地提供解决思路。
With the development of urbanization in China, more and more old industrial sites are being re-paired in the process of urban construction. During the construction of the Weidong New Town project, it is found that there are degraded lands such as abandoned chemical sites. In the presence of contaminated sites, it was found that there were Hg, Pb, and As-standards in the waste chemical plant and domestic sewage outlets. Based on the investigation of soil heavy metals in Weidong New Town, this paper comprehensively analyzed the foreign strategies for soil pollution control to predict the heavy metal Pb in the untreated situation, the migration process in the next 30 years, in order to provide solutions for heavy metal over-standard sites similar to Weidong New City.
