| 摘 要： | 污废水生物处理技术不断地向工艺流程简单、处理费用低和处理效果好的方向发展。磁技术在该领域具有很好的发展潜力。磁场具有生物效应,可增强微生物活性。磁粉能与活性污泥絮体紧密结合,形成具有特殊分离性能并能抑制剩余污泥产生的磁化活性污泥。磁化活性污泥法在日本的污水处理厂有未排泥连续运行2年的成功先例。近年来微生物的磁效应在废/污水生物处理中的应用引起越来越多国内外研究者的注意,磁技术与其他水处理技术之间的结合是比较热门的研究领域。

| Abstract: | The wastewater treatment technology develops towards simple flow scheme,lower costs and good treatment effect. The magnetic technology demonstrates its unique role and potentiality in wastewater treatment. The biological effects of magnetic field could improve the activity of microorganisms. Magnetic particles closely combines with bio - flocculation of activated sludge to form magnetic activated sludge ,which possess features of special separation performance and suppressive effect on production of waste activated sludge. Magnetic activated sludge technique in Japanese sewage treatment plant operates for two consecutive years without excess sludge. The application of magnetic effects of microbial matters in wastewater treatment received much attention. The combination of magnetic technology and other wastewater treatment technological becomes a hot research field. |
