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 目 录一、绪论.......................................................1二、设计内容··················································2三、污水厂的设计规模··········································3四、进出水水质················································3五、处理程度的计算············································3六、城市污水处理设计··········································41、工艺流程的比较·········································42、工艺流程的选择·········································7七、污水处理构筑物设计········································81.粗格栅和提升泵房(两者合建)······························8设计计算··············································82、细格栅和沉砂池·········································11八、污泥处理构筑物的设计计算·································271、污泥泵房··············································27 2、贮泥池··························...
