摘要
循环活性污泥系统(CASS)是一种将变容积活性污泥法和生物选择器原理有机地结合起来,具有同步脱氮除磷的以序批曝气 -非曝气方式运行的充 -放式间歇活性污泥处理工艺。文中主要介绍了循环活性污泥法CASS工艺的发展、应用情况及其工艺特点,就该工艺在我国的应用提出了展望。
Cyclic activated sludge system (CASS) is a batch fill and draw activated sludge process operated in sequences of aeration and non aeration which can simultaneously remove nitrogen and phosphorus, combining variable volume activated sludge processing with biological selector organically.This paper mainly introduces development,application and process characteristics of CASS, and looks forward to applying this process in our country.
