Innovative study of sustainable wastewater treatment technology by magnetic activated sludge process

研究了操作简便、污泥零排放的磁性活性污泥法处理污水的创新技术。在此过程中，磁粉必须吸附在微生物上才能进行磁分离。提出了一种利用磁力牵引解吸微生物体内磁粉的简单方法。提出了磁性活性污泥永磁体磁分离器设计的基本策略，以及染料废水、高氮废水、畜牧业废水净化和污水深度净化的创新工艺。

Innovative wastewater treatment technology by magnetic activated sludge process of easy operation and zero sludge emission was investigated. In this process, magnetic powder must be adsorbed on microorganisms for applying magnetic separation. A simple method for desorption of magnetic powder from microorganisms using magnetic traction was proposed in this research. Also, basic strategy of designing magnetic separators using permanent magnet for magnetic activated sludge and innovative processes for dye wastewater, high-nitrogen wastewater, stock raising wastewater purification, and advanced sewage purification were proposed in this research.
