毕业设计说明书（论文）中文摘要

UASB-CASS工艺全称为厌养好氧二级处理活性污泥法，即污水通过调节沉淀池进入一级和二级UASB反应池，在厌氧状态下产生的沼气，与污泥碰撞引起附着气泡的污泥絮体脱气，污泥颗粒将沉淀到污泥床的表面。

出水进入CASS池实行连续进水、静态沉淀和间歇排水，对污染物质降解经历着“好氧—缺氧—厌氧”交替运行的过程，加之采用延时曝气与生物选择，有效地促进了难降解有机物的好氧生化。

在本次工艺中COD、BOD、SS的去除率达到：

99%、99%、97%，出水达到国家二级标准。

工艺由于投资和运行费用低、处理性能高，尤其是优异的脱磷除氮功能而越来越受到重视。

该工艺已在酒厂含油废水、食品废水、屠宰废水中得到广泛应用，尤其适用于工业污水和生活污水的处理。
