XX 大学土木工程学院 给水排水专业 2025 届毕业设计说 明 书题 目：丁市排水工程扩大初步设计指导老师： 学生姓名： 培育单位：XX 大学土木工程学院班 级：给水排水 00-3提交日期：2025 年 6 月 10 日摘要：丁市位于湘中地区中心，涟涓二水与湘江汇合处，市区从东北至西南长约 30 公里，从东南到西北宽约 24 公里，全市总面积为288.98 平方公里。本地区地质良好，未发现喀斯特、山崩、滑坡等不利于工程建筑的地质现象。丁市受季风影响，湿度大，雨水多、夏季温度高，属于新大陆性气候。采纳雨水，污水分流的管道布置形式。其中污水处理厂采纳以 Carrousel 氧化沟为主体的污水处理工艺流程，和以重力式浓缩池为主体的污泥工艺流程。该工艺具有工艺流程短、处理效果好、出水水质稳定、剩余污泥少、运行管理方便、基建与运行费用低等特点。关键词：初步设计 重力式污泥浓缩池 Carrousel 氧化沟 【 Abstract 】 : The economic and technological development zone is located north of Changsha . It has a total coverage of over 20 square kilometers. This zone is composed of the west of the xiangjiang river Corporation and the east of the xiangjiang river Corporation. According to some relevant materials about ecology, water resources and so on , this article shows a preliminary designation of the sewage treatment and sewage plug treatment . This plant will be constructed by one stage. The water to be treated is 50,000 cubic meters per day. The plant adopt the major technology process for carrousel oxidation ditch and gravitate thickeners. The technology has characterize for short-period process, high efficiency, steady water quality, small rest solids and low fees for construction and operation, and so on. And what, more, it will be operated and managed in a convenient manner.Key words: preliminary designation technology process Carrousel Oxidation ditch gravitate thickeners第 1 章 工程概况1.1、丁市的基本设计资料（即现在的湘潭市）介绍丁市的历史沿革：丁市为一...
