中文摘要：

以溶剂热法合成的聚二乙烯苯(PDVB)树脂为吸附剂,苯、甲苯、二氯甲烷为典型的非极性吸附质,对比单一微波和超声雾化水协同微波条件下树脂的脱附再生效果,考察微波功率、水雾量、吸附质种类等对树脂脱附效果的影响.结果表明,PDVB树脂在单一微波作用下对非极性有机分子的脱附率约为50%,而在超声雾化水协同作用下,PDVB对苯、甲苯、二氯甲烷的脱附率均可达到90%以上.同时脱附床层的温度始终保持在40℃以下,不会造成树脂高温老化,多次吸附/脱附循环再生后,树脂结构仍能保持稳定,表明在微波条件下引入超声雾化水可强化体系的微波吸收能力,实现树脂吸附剂的快速脱附再生.

英文摘要：

Polydivinylbenzene (PDVB) resin synthesized by solvothermal method was used as an adsorbent, and benzene,toluene and methylene chloride were selected as typical non-polar organic pollutants. Desorption performance ofnon-polar organic molecules on PDVB under single microwave irradiation was compared with which introduced ofultrasonic atomized water. The influence of microwave power, atomized water amount, and types of adsorbate on resinregeneration was investigated. The desorption ratio of non-polar organics is about 50% under single microwave irradiation,while the desorption ratio would reach above 90% under microwave radiation cooperated with ultrasonic atomized waterin condition of 640W microwave power and 0.105g/min atomized water amount. The temperature of regeneration bedkept below 40℃, and would not lead to resin aging, also resin structure remained stable after repeatedly adsorption anddesorption. Introducing of ultrasonic atomized water would enhance microwave absorb ability, and improve resinregeneration efficiency.
