水污染控制工程课程设计 1 摘要 本次课程设计的题目为某城市污水处理厂设计,结合当地的水质情况、处理量等多方面因素考虑，选择一体化氧化沟法水处理工艺，使水质达到处理要求，并对各个水处理构筑物进行了尺寸和处理指标方面的计算，最后布置了整体平面图及高程图。 该污水厂的设计处理量为30000 处理厂处理流程为：污水→粗格栅→提升泵房→细格栅→辐流式沉砂池→卡鲁塞尔氧化沟→ 二沉池→接触消毒池→出水。 污泥流程：剩余活性污泥→污泥提升泵房→浓缩脱水一化车间 →污泥外运 污水排放应执行《污水综合排放标准（GB8978－1996）》中的二级标准. 关键词： 污水处理厂 卡鲁塞尔氧化沟 书 目 录 一、绪论1 TOC \o 1-3 \h \z \u 16380 二、设计内容··················································2 1393 三、污水厂的设计规模··········································3 5318 四、进出水水质················································3 22750 五、处理程度的计算············································3 17086 六、城市污水处理设计·········································· 4 32089 1、工艺流程的比较·········································4 21702 2、工艺流程的选择·········································7 10485 七、污水处理构筑物设计········································8 3191 1.粗格栅和提升泵房(两者合建)······························8 13167 设计计算··············································8 13565 2、细格栅和沉砂池········································· 11 19490 八、污泥处理构筑物的设计计算································· 27 30136 1、污泥泵房·············································· 27 2、贮泥池················································27 9362 3、污泥浓缩池··········································· 28 4、排泥泵房··············································29 27423 九、污水厂平面，高程布置·····································30 23642 1、平面布置··············································30 16242 2、管线布置··············································30 8578 3、高程布置 ·············································31 TOC \o 1-1 \h \u 十、 心得体会·················································33 16088 十一、 参考资料···············································34 25664 16836 8947 4755 12857 某城市污水处理厂设计 PAGE PAGE 34 PAGE PAGE 35 一、 绪论 随着社会的发展和人民生活水平的不断提高，环境的污染也变的越来越严重，尤其是对水体的污染使我国的水资源更加贫乏。环境保护是我国的一项基本
