对百事可乐新厂污水处理系统的研究 环境与生物工程学院 2006级生物工程 董宪兵 2006003621 指导老师：黄晓天 摘要：目前世界上主要使用的废水处理方法有活性污泥法、生物膜法、厌氧生物处理法和自然生物处理法。其中活性污泥处理法是比较常见的处理方法。 重庆百事可乐饮料有限公司根据碳酸型饮料生产的特点，采用活性污泥处理法的废水处理工艺，使出水水质可达到GB8978－1996的一级排放标准，COD去除率超过95％。 本文详细介绍了重庆百事公司新厂废水处理系统的工艺研究并简要介绍啦旧厂的废水处理系统，用实验方法分别从COD值、pH值和污泥中微生物的种类数量等方面采集数据证明是否达到排放标准。以及出现一些设备故障，处理过程异常情况的解决方法。 关键词：废水处理 活性污泥法 COD 异常情况处理 Summary:The liquid waste processing method that use mainly in the world has the live dirty mire method, living creature film the method and be disgusted with the oxygen living creature processing method and natural living creature processing currently method.Among them, the live dirty mire processing method is more familiar treatment. The Pepsi-Cola beverage limited company in Chongqing produces according to the carbonic acid type beverage of characteristics, adopt the liquid waste processing craft of live dirty mire processing method, using water fluid matter can attain one class exhaustion standard of GB8978－1996, COD cleans a rate more than 95%. This text introduced the craft research of 100 matter company new factory liquid waste processing systems in Chongqing to combine synopsis introduction in detail the liquid waste processing system of old factory, use experimental methods distinguish the amount of categories etc. of microorganism collect if the data proof attains exhaustion standard from the COD value, pH and dirty mire.And appear some equipments breakdowns, handle the solution method of process excrescent circumstance.
