武汉纺织大学摘 要UASB-CASS工艺全称为厌氧好氧二级处理活性污泥法，即污水通过调节沉淀池进入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。出水进入接触氧化池，经充氧后以一定流速流经填料，与生物膜接触，生物膜与悬浮的活性污泥共同作用，达到净化废水的作用。接着进入CASS反应池池实行连续进水、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：99.75%、99.875%、99.66%，出水达到国家一级标准。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。关键词：工业污水； UASB-CASS工艺； 工艺设计ABSTRACTUASB-CASS Technology called the Aerobic disgust Custody of 2 handle Activated Sludge Process , That By regulating sewage into UASB reactor pool , Anaerobic conditions in the gas , Sludge caused by collision with bubbles attached sludge floc degassing , Sludge particles of sludge bed sediments to the surface.Water into the contact oxidation pool, through the packing after oxygen filling in a certain velocity, contact with biofilm, biofilm and suspended activated sludge combination, to achieve the purification of wastewater. CASS pool water entered the introduction of the continuous inflow, Static precipitators and intermittent drainage, Degradation of pollutants experiencing aerobic - anoxic - anaerobic alternative process, Moreover, using aeration and biological delay choice Effectively promoting the refractory organics aerobic biochemical. In this process of COD, BOD, SS removal rate : 99.75%,99.875%,99.66%. The water reach the state standards of two. Technology investment and operating costs low, Performance superb handling, Particularly outstanding Phosphorus and nitrogen functional and more importance. The process has been in the distillery oily wastewater, food waste water, wastewater slaughtering been widely applied, particularly applicable to the industrial effluents and sewage disposal.Keywords: Industrial sewage ；UASB-CASS technology；process design目录1.概述11.1.工程名称11.2.工程概况11.3.废水来源及特征11.4.地理及气候特征21.5.设计范围21.6.设计依据及规范21.7.设计原则32.废水处理方案的选择及其比较42.1.设计思路42.2.处理工艺方案介绍42.2.1.方案概述42.2.2.方案的比较及确定62.2.3.方案一中各污水处理构筑物对污水的处理效率72.2.4.工艺流程说明83.工
