| 摘 要： | 某生产CaCl_2化工厂因环境问题被停止生产,厂区周边土壤和地下水受到不同程度的污染。为掌握污染土壤中污染因子的含量和地下水受污染情况,布置了土壤采样点和地下水监测点,利用厂区周边已有机民井进行水样采集,通过室内检测、分析研究等工作,得出在厂区周边土壤60～300cm深度范围内存在Ca~(2+),Cl~-富集,鉴于土壤的天然吸附和自净能力,目前条件下,厂区及周边地下水污染状况受影响较小。通过抽水试验、渗水试验和弥散试验,圈定了污染物的影响范围,查明了污染物的影响程度,并在此基础上进行了污染物影响变化情况的预测分析,为后续区域污染地块的风险评估和修复治理工作提供了数据支持。

| Abstract: | The production of CaCl2 chemical plant has been stopped because of environmental problems, and the soil and groundwater around the plant have been polluted to varying degrees. In order to grasp the content of pollution factors and the pollution of groundwater in contaminated soil, soil sampling points and groundwater monitoring points have been arranged, and the water samples collected by organic wells around the plant area have been used for indoor testing, analysis and research. It is concluded that there are Ca2+ and Cl enrichment in the depth range of 60~300cm around the plant. In view of the natural adsorption and selfpurification ability of the soil, under the current conditions, the groundwater pollution situation in the plant area and surrounding areas is less affected. Through the pumping test, water seepage test and dispersion test, the range of influence of pollutants has been delineated, the degree of influence of pollutants has been ascertained, the prediction analysis of the influence of pollutants has been carried out, and data support has been provided for risk assessment and rehabilitation of contaminated land in subsequent areas. |
