Developments of Magnetic Activated Sludge Process with Zero Emission of Excess Sludge.

采用磁分离活性磁污泥法处理城市污水。该装置由7.6m^3的曝气池和一对带有磁鼓的磁分离系统组成。在活性污泥悬浮液中添加Fe_3O_4粉末，可制备活性磁污泥。该工艺于2001年9月启动，预计水处理效果良好，剩余污泥排放量很低。翻译后摘要：作为下一个实验，磁和重力分离器的混合固液分离工艺应用于磁活性污泥法处理城市污水。该装置由7.6m^3的曝气池和带磁鼓的磁分离系统组成。在活性污泥悬浮液中添加Fe_3O_4粉末，可制备活性磁污泥。该工艺于2002年8月启动，在处理水方面表现良好，没有剩余污泥排放。

Activated magnetic-sludge process using magnetic separation was applied for municipal sewage. The apparatus consisted of 7.6m^3 of an aeration tank and a pair of magnetic separation systems with the magnet drum. Activated magnetic-sludge was easily prepared by addition of Fe_3O_4 powder to the activated sludge suspension. The process starts in September 2001 and is expected a good performance on water treatment and very low emission on excess sludge. Abstract :As next experiment, hybrid solid-liquid separation process using magnetic and gravity separators was applied in magnetic activated sludge process for municipal sewage treatment. The apparatus consists of 7.6m^3 of an aeration tank and a magnetic separation system with a magnet drum. Activated magnetic-sludge was easily prepared by addition of Fe_3O_4 powder to the activated sludge suspension. The process started in August 2002 and shows good performance on water treatment without excess sludge emission.
