摘要:
以广东省韶关市大宝山排土场多金属重度污染土壤为研究对象,通过模拟酸雨淋溶实验,研究了淋溶对植物稳定修复(土壤改良+种植红麻/苎麻)后土壤重金属迁移的影响。结果表明,在土柱上层(0-10 cm)土壤中施加0.4 %石灰+ 0.2 %有机肥,能显著提高淋出液pH值,并大幅度降低0-10 cm土壤中的重金属有效态含量;种植红麻和苎麻处理后,淋出液pH值较空白组显著提高,淋溶液淋失量相较于空白处理分别减少了32.5%和12.4%,淋出液中Pb、Zn、Cu、Cd重金属含量分别降低了65.2%和71.3%、81.6%、78.5%和79.4%、71.7%以及86.7%和85.3%;且种植红麻、苎麻后,土柱下层(21-30 cm)的土壤Pb、Zn、Cu、Cd重金属有效态含量相较于空白处理分别降低了16.3%、22.9%、30.5%、17.9%及18.8%、32.5%、38.1%、29.7%。种植红麻、苎麻不仅能显著降低径流淋溶失量,而且降低了淋出液中重金属含量,减轻了淋出液对地下水造成的污染。因此,在模拟酸性降雨条件下,种植红麻、苎麻并施用改良剂处理重金属污染土壤的模式在植物稳定修复方面具有较好的应用潜力。
Abstract:

The soil of Dabao mountain mine dump in Shaoguan, Guangdong has been severely contaminated by heavy metals. By leaching experiment with simulated local acidic rainfall, the effect of soil amendment and plantation of kenaf (Hibiscus cannabinus) and ramie (Boehmeria nivea L.) on the migration of heavy metal was studied. The result showed that the addition of 0.4% lime 0.2% organic fertilizer to the soil column (0-10 cm) significantly increased the pH of leaching solution and greatly reduced the available heavy metal content in 0-10 cm soil. After planting kenaf and ramie, the pH of leachate was significantly higher than that of blank group. The leaching loss of leachate decreased by 32.5% and 12.4% respectively and the Pb, Zn, Cu, Cd in the leachate was decreased by 65.2% and 71.3%, 78.5% and 79.4%, 71.7% and 86.7% and 85.3%, respectively, compared with the blank treatment. After planting kenaf and ramie, the available heavy metal content of Pb, Zn, Cu, Cd in soil in the lower layer of soil column (21-30 cm) was reduced by 16.3%, 22.9%, 30.5%, 17.9%18.8%, 32.5%, 38.1%, 29.7%, respectively, compared with the blank treatment. Planting kenaf and ramie can not only reduce the leaching loss significantly, but also cut down the heavy metal concentration in leachate, thereby reducing the pollution caused by leachate to groundwater. The pattern of planting kenaf and ramie and applying amendment to treat heavy metal contaminated soil under the condition of simulated acidic rainfall has a great utilization potential in phytostabilization.
