| 摘 要： | 针对小型造纸厂污水处理问题.开展了超导磁分离技术研究.设计并研制出制冷机直接冷却的高温超导磁体,磁体中心磁场在直流运行状态下达到1.48 T,交流运行状态达3.92 T.利用该超导磁体对造纸厂废水进行了磁分离处理.实验中,预先在废水中加入经过表面等离子有机改性的铁磁性颗粒,并与污水中非磁性有害物质絮接,通过强磁场实现水中污染物的分离.实验结果表明,经磁分离处理的集水池废水COD值由起始的1 780 mg/L降到147 mg/L,净化效果良好.讨论了利用等离子体聚合薄膜制备具有强捕捉能力的磁性粒子工艺.

| Abstract: | Traditional wastewater purifying methods are expensive and involve heavy facility investment, long time in treatment, and a requirement of large land area. In this paper, the purification of wastewater in small scale paper factories by using superconducting magnetic separation method is proposed. High Tc superconducting magnet cooled directly by cryocooler is designed. The centralmagnetic field can reach 1.48 Tesla and 3.92 Tesla in Direct Current (DC) and Alternating Current (AC) modes, respectively. In or... |
