摘要
本调查以华东某市石油化工厂拆迁场地为研究对象。该场地拆迁过程中储罐破损,造成污染泄露。通过对场地内土壤、地下水、地表水调查明确地块内主要污染物为氯乙烯、1,1-二氯乙烯、1,1-二氯乙烷、氯仿,均为挥发性氯代烃,以DNAPL为主;该类污染泄漏在短时间内不会对土壤造成污染,在地下水中的横向迁移扩散趋势不明显。因此建议地下水水位埋藏较浅地区,发现污染泄漏初期应尽早清除污染源,并对地下水进行修复,防止污染物进一步扩散。
In East China,a chemical demolition site as research object.The storage tank was damaged and causing pollution leakage in the process of dismantling.Through the site investigation,the main pollutants was identified in this survey area were vinyl chloride,1,1-dichloroethylene,1,1-dichloroethane,and chloroform,which were volatile Chlorinated aliphatic compounds.The compounds were mainly DNAPL.DNAPL leakage will not cause soil pollution in a short time,and the lateral migration and diffusion trend in groundwater is not obvious.Therefore,it is suggested that the groundwater level is buried relatively shallow,and the pollution source should be cleared as early as possible in the early stage when pollution leakage is discovered,and the groundwater should be repaired to prevent further spread of pollutants.
