摘要
为了排查某化工企业的土壤隐患,对其进行土壤环境调查。通过土壤隐患排查确定隐患排查的土壤污染物种类为有机物污染、重金属污染、酸碱污染。场地共布设土壤采样点10个,采集土壤样品16个。结果显示,挥发性有机物与半挥发性有机物未检出,土壤环境整体呈轻度酸化和轻度碱化,土壤检测出的重金属离子浓度均小于筛选值。使用Voxler4.0作土壤样品中重金属镍的空间展布模拟图,表明土壤中无机重金属随地下水流运动发生迁移富集的特征。该化工企业土壤污染隐患总体较低,但存在部分土壤污染隐患,需采用防治措施避免土壤环境污染。
In order to investigate the potential soil hazards in a chemical enterprise,the soil environment was investigated.Through the investigation of potential soil hazards,it is determined that the types of soil pollutants are organic pollution,heavy metal pollution and acid-base pollution.There were 10 soil sampling sites and 16 soil samples.The results showed that volatile organic compounds and semivolatile organic compounds were not detected,the soil environment was slightly acidified and alkalized,and the concentrations of heavy metal ions detected in soil were lower than the screening values.Voxler 4.0 was used to simulate the spatial distribution of heavy metal nickel in soil samples,which indicated that inorganic heavy metals in soil migrated and accumulated with the movement of groundwater flow.The hidden dangers of soil pollution in this chemical enterprise are generally low,but there are some hidden dangers of soil pollution.Prevention and control measures should be adopted to avoid soil environmental pollution.
