中文摘要：

为了探索旋转填料床中不同填料对废水中丙烯腈去除率的影响,并为超重力气提丙烯腈废水工艺优选合适的填料提供参考,分别在装有填料A和填料B的旋转填料床中进行气提丙烯腈废水的实验.在相同的工艺条件下对比考察了填料A和B对丙烯腈去除率的影响.结果表明：在实验操作条件范围内,填料A和B的丙烯腈去除率均可达60％以上;更换高效的填料有助于丙烯腈去除率的提高,且气液比对丙烯腈去除率的增幅影响最为显著,超重力因子β次之;与填料A相比,仅考虑丙烯腈废水处理效果和处理成本,填料B更适用于超重力气提工艺中的旋转填料床.研究结果为选取适宜的旋转填料床填料以及超重力气提工艺的工业化应用提供一定依据.

英文摘要：

In order to explore the treatment effect of acrylonitrile wastewater in the rotating packed bed （RPB） with different packings and appropriate packings for high gravity air stripping acrylonitrile wastewater technology, the experiments on air stripping acrylonitrile wastewater in the RPB loaded with packing A and packing B respectively were carried out. The effects of packing A and packing B on the removal rate of acrylonitrile were studied comparatively under the same conditions. The results show that the removal rate of acrylonitrile can reach more than 60% with packing A and packing B under the operating conditions. The efficient packing is helpful to improving the removal rate, and the influence of gas-liquid ratio on the removal rate of increase amplitude is most significant, followed by high gravity factor. Compared with the packing A, only considering the effect and cost of acrylonitrile wastewater treatment, packing B is more suitable for the RPB by high gravity air stripping technology. The results provide reference for selection of packing in RPB and industrial application of high gravity air stripping technology.
