磁活性污泥法在污水处理中的应用

摘要

磁活性污泥法是对传统活性污泥法的一种改良.相对于传统活性污泥法,磁活性污泥法减小了生物反应器占地面积、提高了处理负荷、改善了脱氮除磷效果、有效控制丝状菌污泥膨胀、降低剩余污泥产量.该文介绍了磁活性污泥法的技术原理及研究与应用进展,对磁活性污泥法存在的问题进行了初步探讨并对该技术的应用前景进行了展望.%Magnetic activated sludge process (MAS) is a kind of modification for conventional activated sludge process. Compared to conventional activated sludge process, the magnetic activated sludge (MAS) process can reduce the site area of bio-reactor, increase treatment load, improve removal effect of nitrogen and phosphorus, control the filamentous sludge bulking effectively, decrease amount of excess sludge. The research and application process of the magnetic activated sludge process was introduced in the paper. Problems in the magnetic activated sludge process were discussed and the future prospects of this technology were outlooked.
