1、污水处理A2O工艺摘要3本次毕业设计的题目为新建城市污水处理厂设计（15万m/天）工艺。主要任务是完成个该地区污水的处理设计。其中初步设计要完成设计说明书一份、污水处理厂总平面图一张及污水处理厂污水与污泥高程图一张；单项处理构筑物施工图设计中，主要是完成平面图和剖面图及部分大样图。该污水处理厂工程，规模为15万吨/日。2A/O工艺的生物处理部分由厌氧池、缺氧池和好氧池组成。厌氧池主要功能是释放磷,同时部分有机物进行氨化。缺氧池的主要功能是脱氮。好氧池是多功能的,能够去除BOD、硝化和吸收磷。该污水厂的污水处理流程为：从泵房到沉砂池，进入反应池，进入辐流式二次沉淀池，再进入清水池，最后出水

2、；污泥的流程为：从反应池排出的剩余污泥进入集泥配水井，再由污水泵送入浓缩池，再进入消化池，最后进入脱水机房脱水，最后外运处置。关键词：A2O；同步脱氮除磷；设计说明书AbstractThetopicofthisgraduatedesignisaboutthedesignofthesewagedisposalplantintheareaofaCity.ThetechnicsoftheplantistheAnaerobic-Anoxic-Oxic.Themaintaskistheprimarydesignoftheplant.Thetaskoftheprimarydesignisthatade
