典型印染企业土壤污染状况初步调查研究

Preliminary Investigation and Study on Soil Pollution Status of a Typical Textile Dyeing Enterprise

为调查印染企业遗留地块土壤及地下水污染状况,以典型印染企业为研究对象,采取资料收集、现场踏勘、人员访谈等方式对地块历史生产情况及污染特征进行综合分析,识别出地块潜在污染物、污染途径、潜在污染区域,通过调查监测方案制定、现场采样、实验室检测、数据分析等工作得出结论。结果表明:本次采集的45个土壤样品、4个地下水样品中,各项检测指标检测结果均低于相应标准限值,表明该印染企业在历史生产过程中,对地块土壤及地下水污染影响较小,满足后期规划用地要求,无须继续开展土壤污染状况详细调查工作。

In order to investigate the soil and groundwater pollution in brownfield site of the textile dyeing enterprise,a typical textile dyeing enterprise is taken as the object of study.The historical production situation and pollution characteristics of the plot were comprehensively analyzed by means of data collection,on-site surveys and personnel interview,and potential pollutants,pollution routes and potential pollution areas of the plot were identified.Conclusions were drawn through investigation and monitoring plan formulation,field sampling,laboratory testing and data analysis.The results showed that among the 45 soil samples and 4 groundwater samples,the detection indicators were lower than the corresponding standard limits,indicating that the printing and dyeing enterprise had little impact on soil and groundwater pollution in the historical production process,which met the requirements of later planning land use,and there was no need to continue to carry out detailed investigation.
