摘要
循环活性污泥法CASS工艺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—非曝气方式运行的间歇活性污泥处理工艺。主要介绍了CASS工艺的原理、运行方式及其设计计算,并对该工艺在国内的应用前景进行了展望。
Cyclic activated sludge system (CASS) originates from subsequence activated sludge system, combining variable volume activated sludge processing with biological selector organically, on which can simultaneously remove nitrogen and phosphorus. This paper mainly introduces the principle, operating mode and designing calculation of CASS, and looks forward to applying this process in our country.
