  • 摘要: 三氯乙烯(TCE)是污染土壤和地下水中检出率较高的氯代有机物。以TCE为研究对象,考察了地下水无机成分和腐殖酸对高锰酸钾氧化TCE的影响,研究了不同离子强度下的MnO2颗粒行为,并测定了泥浆系统中TCE的氧化效果,结果表明:当TCE初始浓度为20 mg/L、高锰酸钾与TCE的摩尔比为2∶1,离子浓度+、Cl-、HCO3-对TCE的去除率影响甚微,但离子强度对MnO2的沉淀生成影响显著;0.1 mol/L的K+对TCE的去除有一定程度的抑制;0.1 mmol/L的Fe2+和腐殖酸对TCE的氧化有显著负面影响。泥浆系统实验进一步验证了有机质对高锰酸钾氧化TCE的影响很大。
    Abstract: Trichloroethylene (TCE) is a common chlorinated hydrocarbon contaminant frequently detected in soil and groundwater. In this study, TCE was chosen as the target contaminant. The effects of inorganic constituents in groundwater and humic acid (HA) on TCE oxidation using KMnO4 were investigated in aqueous system, meanwhile the MnO2 particle performance under various ion strength conditions and TCE removal performance in slurry system were evaluated. The results showed that over 98% TCE removal could be achieved under the experimental conditions: initial TCE concentration of 20 mg/L, KMnO4/TCE molar ratio of 2∶1 and ionic concentration of +, Cl- and HCO3- had less effect on TCE removal efficiency, but the ionic strength had significant influence on MnO2 precipitation. 0.1 mol/L K+ could cause inhibition to TCE removal to some extent, whereas HA and 0.1 mmol/L Fe2+ had apparently negative effects on TCE oxidation. The tests in slurry system further demonstrated that the organic matters have a significant impact on TCE oxidation by KMnO4.
