膜技术在挥发性有机蒸汽(VOC)处理中的应用

Application of membrane separation technique to Disposal of VOC

有机蒸汽(VOC)排放到大气中会引起健康,环境、安全等一系列问题。采用膜技术来处理VOC具有投资较小、分离效率高、能量消耗低、操作简单、不形成二次污染等优点,所以在处理VOC方面有着广泛的应用。文中介绍了膜分离技术处理有机蒸汽的原理,膜法处理有机蒸汽的过程及其工艺流程。

VOC emitted to atmospheric environment brings to serious problems for example environmental pollution, risks to human heath and public safety ,etc. with the merits of low cost, high ratio of separation, oaring energy, simple and convenient operation, none secondary pollution, membrane separation technique ,which is widely applied to VOC treatment, can clear up VOC . in this paper the process and removing mechanism of membrane separation technique was introduced.
