| 中文摘要 |
| 利用改装的家用微波炉、微波无电极灯(EDLs)和TiO2催化剂研究了水溶液中苯酚的光催化降解效果.结果表明,反应30 min,微波辅助光催化(MAPC)能去除92%的苯酚,溶液总有机碳(TOC)减少84%.MAPC的最佳反应条件为:苯酚初始浓度10 mg/L,微波功率900 W,反应液体积50 mL,EDLs-3,催化剂用量1～4 g/L,循环态流速15 mL/min.MAPC处理含酚废水具有较好的应用潜能. |
| 英文摘要 |
| Experimental study on microwave assisted photocatalytic degradation of phenol in aqueous solution was carried out with modified domestic microwave oven,electrodeless discharge lamps(EDLs) and TiO2 catalyst.Results showed that the removal rate of phenol in the MAPC process was 92% after 30 min reaction.Loss of total organic carbon(TOC) was 84%.The optimal conditions for the MAPC method were 10 mg/L phenol,900 W MW output energy,50 mL solution volume,EDLs-3,1～4 g/L catalyst dosage and 15 mL/min of flowing velocity in the circulating mode.The MAPC process was promising in treating phenolic waste water. |
