介质阻挡放电处理水中有机污染物研究进展

Research Progress of Organic Pollutants Treatment in Wastewater by Dielectric Barrier Discharge

介绍了不同结构水处理反应器的优缺点,叙述了介质阻挡放电(DBD)低温等离子体技术处理溶液中有机物的效能,总结了均相、非均相催化DBD的研究现状。根据现有DBD技术在处理有机污染废水中的不足,认为反应器结构仍需进一步优化来减少热能消耗,催化DBD技术需考虑非均相催化剂的回收利用或处置。如何提高能量利用效率、降低成本、将技术推向工业化应用是今后的研究方向。

The advantages and disadvantages of water treatment reaction with different structures were introduced, organic pollutants treatment efficiency by dielectric barrier discharge （DBD） low-temperature plasma technology was described, and the research status of organic pollutants treatment by, homogeneous and heterogeneous catalytic DBD were summarized. According to the shortage of existing DBD technology in the organic pollutants treatment in wastewater, the reactor structures would be considered fiather optimized to reduce the heat energy consumption, and the recovery and utilization of heterogeneous catalysts would be considered in the catalytic DBD process. Improving energy utilization efficiency, reducing costs and industrial application were the research direction in this field.
