唐 山 学 院毕 业 设 计设计题目：氧化沟法处理城市废水的工艺设计 系 别： 环境与化学工程系 班 级： 12 环本 2 班 姓 名： 李增光 指 导 教 师： 刘昆 2 0 0 6 年 6 月 8 日氧化沟法处理城市废水的工艺设计摘要众所周知，地球是水的星球，水大概占到地球表面积的五分之四，然而地球的淡水资源确特别少。近些年来，随着中国城市化和工业化进程的发展，我国的污水废水排放也是与日俱增。城市污水的重要来源：（1）生活污水，主要来自于家庭生活用水，办公费谁公共设施废水和雨水。(2）工业废水，工业生产中用于冷却洗涤等的废水。城市污水里面所含生活污水较多，生化性良好，一般较好处理。本次设计的主要内容是 80000m³/d 的某城市污水处理厂氧化沟工艺设计，本次设计的主体工艺是改良式卡鲁塞尔氧化沟工艺，污水通过粗格栅，提升泵，细格栅，沉砂池，改良式卡鲁塞尔氧化沟，消毒间等各个工艺而达到出水要求。 关键词：城市污水处理 改良式卡鲁塞尔氧化沟 主体工艺 Oxidation ditch process of urban wastewater treatment process designAbstractPlanet, it is well known that the earth is tax water accounts for about of the surface of the earth, but the earth's fresh water resources is a particular less. In recent years, with the development of China's urbanization and industrialization process, sewage waste wa -ter emissions in China is also growing.An important source of urban sewage: 1. The life sewage, water mainly comes from the home life, office who public facilities, waste water and rainwater. 2. Industrial waste water, industrial production is used for cooling and washing wastewater.Urban wastewater contains so many domestic sewage inside, biochemical, general good processing. The main content of this design is 80000 m after a/d city sewage trea- tment plant oxidation ditch process design, the main body of the design process is improved carrousel oxidation ditch process, the sewage through the coarse grid, lift pump, fine grille, grit chamber, i...
