1008-1542 article 響應面法優化微波修復萘污染土壤工藝參數的研究 Optimization of microwave remediation of naphthalene contaminated soil by response surface methodology 為了研究石油污染土壤微波修復的最佳工藝,選取石油污染土壤中典型的半揮發性有機物萘(naphthalene,Nap)為目標污染物,以模擬的萘污染土壤為供試土壤,通過微波對其進行修復。在單因素實驗基礎上,采用響應面法的Box-Behnken實驗設計,以Nap的去除率為響應值,建立以微波功率、輻照時間、土層厚度和土壤含水率為影響因子的二次多元回歸模型。經方差分析(ANOVA)模型達到極顯著水平,其中微波功率的影響最顯著,得到最佳工藝參數:微波功率為768 W,輻照時間為19 min,土層厚度為3.2 cm,含水率為16%,此條件下Nap去除率為97.3%。驗證實驗的Nap去除率為97.0%,與模型預測結果僅偏差0.31%,表明利用響應面法優化的微波修復Nap污染土壤的工藝參數合理可行。研究結果為微波土壤修復技術的工業化應用提供數據依據。 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. 土壤修復;石油污染;微波;響應面法;萘 solid pollution control engineering; microwave; petroleum pollution; soil remediation; response surface methodology 郭斌,龍飛 郭斌,Longfei 河北科技大學 Hebei University of Science and Technology hbkjdx/article/abstract/QB202009260152
