为了研究石油污染土壤微波修复的最佳工艺，选取石油污染土壤中典型的半挥发性有机物萘（naphthalene，Nap）为目标污染物，以模拟的萘污染土壤为供试土壤，通过微波对其进行修复。在单因素实验基础上，采用响应面法的Box-Behnken实验设计，以Nap的去除率为响应值，建立以微波功率、辐照时间、土层厚度和土壤含水率为影响因子的二次多元回归模型。经方差分析（ANOVA）模型达到极显著水平，其中微波功率的影响最显著，得到最佳工艺参数：微波功率为768 W，辐照时间为19 min，土层厚度为3.2 cm，含水率为16%，此条件下Nap去除率为97.3%。验证实验的Nap去除率为97.0%，与模型预测结果仅偏差0.31%，表明利用响应面法优化的微波修复Nap污染土壤的工艺参数合理可行。研究结果为微波土壤修复技术的工业化应用提供数据依据。
In order to study the best technology of microwave remediation of petroleum contaminated soil, the typical semi volatile organic compounds Naphthalene (Nap) in petroleum contaminated soil was selected as the target pollutant, and the simulated Nap contaminated soil was taken as the test soil. On the basis of single factor experiment, the Box-Behnken experiment design of response surface method was adopted, and the removal rate of Nap was taken as the response value. The quadratic multiple regression model was established with microwave power, irradiation time, soil thickness and soil moisture content as the influencing factors. The ANOVA model reached a very significant level, in which the microwave power had the most significant effect. The results showed that the wave power was 768 W, the irradiation time was 19 min, the soil thickness was 3.2 cm, the water content was 16 %, and the removal rate of Nap was 97.3%. The results showed that the removal rate of Nap was 97.0%, which was only 0.31% different from the predicted results. The results showed that the process parameters optimized by response surface methodology were reasonable and feasible.
