摘要:为了寻找成本低廉、环境友好、高效的重金属Cd和Zn淋洗剂，选取雅安市汉源县矿区污染土壤作为供试土壤，采用浓度0.3% KCl盐溶液提取金针菇菌渣(FVr)、茶树菇菌渣(AAr)、花生壳(AHL)和甘蔗皮(SOr)4种农业废弃生物质材料所得浸提液作为淋洗剂，通过恒温振荡淋洗实验探讨上述淋洗剂不同浓度、pH和时间条件下对污染土壤中镉(Cd)和锌(Zn)的淋洗效果。结果表明，4种生物质材料盐浸提液对Cd的淋洗率依次为FVr > SOr > AHL > AAr；对Zn的淋洗率则依次为SOr > FVr > AHL > AAr。随浓度上升，除FVr盐浸提液对土壤Cd和Zn的淋洗率呈线性增加外，其余盐浸提液对其淋洗率呈幂函数增长趋势。随pH增加，FVr和AAr、AHL和SOr盐浸提液对Cd和Zn的淋洗率分别呈对数、幂函数下降趋势(P<0.01)。随淋洗时间延长，4种生物质盐浸提液对土壤Cd和Zn的淋洗率变化均呈对数增加趋势(P<0.01)。综合淋洗率和土壤性质的变化，FVr与SOr盐浸提液在浓度为7%，pH为3的条件下持续振荡淋洗1 h可达到最佳淋洗效果，其对Cd的淋洗率分别为76.38%和49.54%；对Zn的淋洗率分别为29.24%和30.75%。FVr和SOr是具有一定潜力的重金属污染土壤修复生物质材料。

Abstract:In order to develop low-cost, environmentally friendly and high effective washing agents for heavy metals of cadmium (Cd) and zinc (Zn), the contaminated soil in mining area of Hanyuan county in Ya'an city was taken as test field, and 0.3% KCl solution extracted liquid from four kinds of agricultural waste biological materials, including Flammulina velutiper residue (FVr), Agrocybe aegerita residue (AAr), Arachis hypogaea Linn shell (AHL) and Saccharum officinarum rind (SOr), was taken as washing agent. Batch oscillating soil washing experiment at constant temperature was conducted to investigate the Cd and Zn washing efficiencies under the conditions of different concentration, pH value and washing time. Results showed that the orders of soil Cd and Zn washing efficiencies by the four biological material salt-extracted liquids were FVr>SOr >AHL>AAr and SOr>FVr>AHL>AAr, respectively. The washing efficiencies of soil Cd and Zn linearly increased with the increasing concentrations of FVr salt-extracted liquid, but increased as a power function model with the increasing concentrations of other three biological material salt-extracted liquids. With the increasing pH, the washing efficiencies of Cd and Zn logarithmically declined by using the salt-extracted liquids of FVr and AAr, but decreased as power function models by using the salt-extracted liquids of AHL and SOr (P<0.01). With the extension of washing time, the washing efficiencies of Cd and Zn logarithmically increased (P<0.01) by using four salt-extracted liquids. Considering the washing efficiency of the two heavy metals and the change of soil properties, the optimum washing efficiencies occurred at 7% the salt-extracted liquids of FVr and SOr, pH of 3, and 1 h contact time, and they were 76.38% and 49.54% for Cd and 29.24% and 30.75% for Zn, respectively. FVr and SOr could be potentially promising agricultural waste biological materials for Cd and Zn contaminated soil remediation.
