摘要
CAST工艺是SBR工艺的一种新形式，近年来在国内中小型污水处理项目中得到广泛应用。根据国内A城市污水处理厂的规模、污水水质情况和脱氮除磷要求，设计选用CAST工艺，并根据项目实际情况及相关经验，对CAST工艺进行有针对性的研究及设计改进。
CAST technology is a new form of SBR technology, in recent years in the domestic small and mediumsized sewage treatment project obtains the widespread application. In this paper, according to the domestic A city sewage treatment plant, the scale of sewage quality and nitrogen and phosphorus removal requirement, using CAST technology, and according to the actual project situation and correlative experience, on the CAST technology was targeted for research and improved design.
