某高校5000m3/d食堂废水处理工艺设计 摘要：食堂废水的处理近年来越来越受到重视。食堂废水的特点是可生化性好，适合采用生物处理的方法如：活性污泥法、生物膜法等。SBR有很多的优点，例如SBR工艺运行稳定，对有机物的去除效果好，抗冲击负荷能力强，产泥量小，不发生污泥膨胀，反应推动力大，能在低温环境中长期运行，并保持高的处理效率。与其他二级处理相比SBR工艺投资少、运行费用低、管理方便。? 根据设计任务，本设计选用SBR做为食堂废水污水的处理工艺，具有投资少，运行费用低，自动化程度高，噪音小的特点，并且处理水质能达到国家规定的排放标准。本设计说明书重点说明了SBR工艺在处理食堂废水时所采用的运行参数、设计的计算方法和过程，以及一些常用水处理构筑物的设计计算方法，通过设计能达到预期的处理效果。?关键词：食堂废水??活性污泥法??SBR ?5000m3/d?of?食堂wastewater?treatment?process?
