【摘要】 用动态土柱法研究芦苇湿地土壤对苯酚的净化效果及其影响因素。结果表明,同原状生长芦苇土柱、原状不生长芦苇土柱相比,模拟土柱对高、中、低三个浓度的苯酚均具有较好的净化效果,且对低浓度苯酚的净化效果最好;芦苇可以通过改变根际和非根际土壤性质以及溶液在土壤中的滞留时间,从而影响湿地土壤对苯酚的净化能力。更多还原

【Abstract】 The study on the purification ability of reed wetland soil and influence factors of the phenol by dynamic method was conducted. Results indicated that, compared with soil column with reed-planted and soil column without reed-planted, simulated soil column had a high purifying efficiency to three concentrations of phenol, especially to low concentrations of phenol. Through changing the residence time of solution in soil and physicochemical properties of rhizosphere, reed can disadvantageously affect the purifying efficiency of wetland soil to phenol.更多还原
