摘要

摘要: 微波热脱附土壤中的有机污染物凭借高效、清洁等优点受到广泛关注。近年来,多数微波土壤热脱附研究装置均由家用微波炉改造而来,无法满足微波热脱附实际应用所需的高功率、高精度温度控制等条件。因此,选用苯系物中的邻二甲苯作为目标污染物,以自配污染土壤为样品,采用自制微波热脱附装置为平台进行实验,针对微波功率、微波加热时长、土壤含水率等工艺条件进行单因素影响实验。同时,构建微波加热土壤模型,设置相同条件,并得到相符的结果。并利用该模型推测其他单因素影响实验的假设。实验与模拟结果表明:微波对土壤热脱附的最佳功率为1600 W,热脱附时间为27 min,含水率为17%,推测样品放置于临近加热腔中心位置时对邻二甲苯去除率最佳。

Abstract: Microwave thermal desorption of organic contaminants from soil has gained much attention due to its high efficiency and cleanliness. In recent years, most of the microwave soil thermal desorption research devices are converted from household microwave ovens, and cannot meet the high power requirement for the practical application of microwave thermal desorption, high-precision temperature control, and other conditions. Therefore, in this paper, o-xylene in benzene was chosen as the target pollutant, the self-matched contaminated soil was used as the sample, a self-made microwave thermal desorption device was used as the platform for the experiments, and single-factor influence experiments were conducted for the process conditions such as microwave power, microwave heating duration, and soil moisture content, etc. Meanwhile, a microwave heating soil model was constructed, the same conditions were set, and the matching results were obtained. The model was also used to speculate the hypothesis of other single-factor influence experiments. The experimental and simulation results showed that the optimal power of microwave thermal desorption of soil was 1600 W, the thermal desorption time was 27 min, the water content was 17%, and it was presumed that the best removal rate of o-xylene was achieved when the sample was placed near the center of the heating chamber.
