重金属污染地块现状及土壤污染修复建议——以原江西日久电源科技有限公司区域为例

Status Quo of Heavy Metal Contaminated Land and Suggestions for Soil Pollution Remediation——Take Jiangxi Rijiu Power Technology Co.,Ltd. As an Example

利通过对原江西日久电源科技有限公司地块加密布点采土壤样的分析,摸清了污染地块的现状,土壤中铅、砷检出超标位置分布在极板车间、应急池位置、储罐区域表层局部区域,铅超标倍数0.038~2.372,砷超标倍数0.16~0.22,同步确定了调查区域内的土壤修复面积及方量。针对这些重金属超标污染的区域土壤,比较了植物微生物联合修复、土壤阻隔填埋技术、化学淋洗技术及固化稳定化联合修复这4种土壤修复方案的优缺点,发现固化稳定化联合修复在经济、技术上优势明显,可净化铅砷重金属污染地块的土壤质量,能满足地块可再开发利用的目的.

Collect soil samples from the site of the original Jiangxi Rijiu power technology Co.,Ltd. found out the present condition of the soil in the polluted plot, the locations where the lead and arsenic in the soil were detected exceeded the standard were distributed in the polar plate workshop, the location of the emergency pool, and the local area of the soil surface in the storage tank area. The lead exceeding standard multiple is 0.038-2.372, and the arsenic exceeding standard multiple is0.16-0.22, simultaneously determine the area and volume of soil remediation in the survey area. For these regional soils contaminated with excessive heavy metals, compared the joint repair plant microbes, soil block landfill technology, chemical leaching technology and curing stabilization joint repair the advantages and disadvantages of four kinds of soil restoration scheme, found curing stabilization joint repair obvious advantages in economy and technology, can purify the heavy metals lead, arsenic pollution plots of soil quality, and can satisfy the plot to the purpose of the development and utilization.
