英文摘要	A series of laboratory experiments were carried out in this study to investigate the remediation of phenanthrene contaminated soil using ultrasound and soil washing. The results indicated that ultrasound and soil washing could significantly enhance the remediation efficiency of each other. The performance of the combined ultrasonic and soil washing process was then investigated, and the impacts of four experimental variables including the initial concentration of phenanthrene in soil, sonication time, pH of washing solution, and washing flow rate were examined using an orthogonal experimental design method. The analysis of variance (ANOVA) of experimental results revealed that the initial phenanthrene concentration, sonication time and soil washing flow rate showed significant effects (P a parts per thousand currency sign 0.05) on the remediation efficiency. A pseudo-first-order kinetics model was developed for describing the remediation process, and a maximum remediation efficiency of 69.5% was observed in the study after 20 min of treatment under the experimental conditions. Therefore, the results indicate that the combined ultrasonic and soil washing process could represent a promising technology for the effective remediation of phenanthrene contaminated soil.; Environmental Sciences; Geosciences, Multidisciplinary; Water Resources; SCI(E); EI; 3; ARTICLE; 5; 1487-1496; 66
