中文摘要: 由采矿、冶炼、加工及废弃物处置等造成的重金属污染土壤问题日益严重,环境污染影响越显突出。围绕云雾苔草与蜈蚣草超富集植物间种对重金属污染土壤联合修复的运用与实践进行试验探索。结果表明:分别采用云雾苔草、蜈蚣草和两者间种联合修复重金属污染土壤,铅、锌、铜、镉、砷等重金属含量均呈逐年下降趋势,间种方式的修复效果明显优于单独种植修复重金属的效果。采用云雾苔草和蜈蚣草间种方式联合修复重金属土壤,对污染土壤的重金属修复效果持续有效,土壤中铅、锌、铜、镉、砷的浓度可降低至12.54 mg/kg、40.21 mg/kg、11.23 mg/kg、0.06 mg/kg和0.32 mg/kg。
Abstract:The issue of heavy metals contaminated soil, caused by mining、smelting、machining and waste disposal, has become increasingly serious, the impact of environmental pollution get more remarkable. The explorative experiments of application and practice of combined remediation of heavy metals contaminated soil were conducted by intercropping of hyperaccumulator Carex nubigena and Pteris vittata. The results showed that: all of the Lead, zinc, copper, cadmium, arsenic and other heavy metal contents are declining trend year by year, whether using Carex nubigena phytoremediation, Pteris vittata phytoremediation or combined remediation. The effectiveness of combined remediation was more competitive. The effectiveness of heavy metal remediation of contaminated soil can be sustainable by adopting intercropping of Carex nubigena and Pteris vittata. The heavy metal concentration of lead, zinc, copper, cadmium and arsenic in the solid were reduced to 12.54 mg/kg、40.21 mg/kg、11.23 mg/kg、0.06 mg/kg and 0.32 mg/kg.
