Research progress of microwave induced catalysis technology applied for wastewater treatment

微波诱导催化技术利用某种强烈吸收微波的"敏化剂"把微波能传给有机污染物而诱发其降解来实现污水的净化,同时可以协同其他水处理技术提高污染物质的去除率,加速处理进程。目前,微波诱导催化技术在污水处理领域的研究主要集中在选择合适的催化剂来处理各种难降解有机污染物和辅助高级氧化技术,具有氧化快速、矿化度高、不带入新的污染物、省时节能、简化操作程序、能使处理工程小型化和分散化等优点。微波诱导催化技术将成为一种经济、高效、具有广阔发展前景的污水处理技术。

Microwave induced catalysis technology utilize a microwave absorption sensibilizer which can pass the energy to organic pollutants to degradate them and purify the wastewater, furthermore, it can help other wastewa- ter treatment technologies improve the removal rate of pollutants and accelerate the treatment process. At present, researches of microwave induced catalysis applied for wastewater treatment mainly focus on choosing right catalysts to treat hard-degradable organic pollutants and assist senior oxidation technologies. The said technology has many advantages, including： rapid oxidation, high mineralization, no new contamination be dragged-in, time-saving, simplified procedures, miniaturization and decentralization of the project and so on. Therefore, it can be said that microwave induced catalysis will be a economical, efficient and great promising wastewater treatment technology.
