摘要
以某电解铝厂所在区域作为研究对象,对无组织排放车间降尘和有组织排放烟气收尘中的氟化物形态检测数据进行了分析,同时对其周边土壤表层和深层中的氟化物含量连续监测进行了对比,研究不同时期氟化物对土壤环境的积累影响。结果表明,含氟烟气以有组织和无组织的形式排放外环境,通过大气沉降形成土壤的氟污染,土壤中氟化物均以微溶或难容的氟化物形态存在,但经过风险评估认为目前区域土壤总危害指数小于1,处于可接受风险水平。
Taking the region of one electrolytic aluminum plant as the study object,it analyzed the fluoride form detection data from the dedusting of an unorganized emission workshop and fume collection of organized emissions,it compared the continuous monitoring of fluoride content in the surrounding soil surface and deep part,and it studied the accumulated effect of fluoride from different periods on the soil environment.The results show that the fluorine-bearing fume discharged into the environment in organized and unorganized forms,then the fume forms soil fluorine pollutants by atmospheric deposition,the fluoride contained in soil exists in form of slightly soluble or insoluble,but it is determined by the risk assessment,that the total hazard index of the soil in the region is less than 1,and it is at an acceptable level of risk.
