水污染控制工程课程设计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1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··············································272、贮泥池················································273、污泥浓缩池···········································284、排泥泵房··············································29九、污水厂平面，高程布置·····································301、平面布置··············································302、管线布置··············································303、高程布置·············································31十、心得体会·················································33十一、参考资料···············································340某城市污水处理厂设计一、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国策，对环境的保护和治理已经刻不容缓。坚持经济建设、城乡建设、环境建设、同步规划、同步实施、同步发展的方针，开展以城市为中心的环境综合治理，以实现经济效益、社会效益和环境效益的统一，并结合环境保护法和水污染防治法进行城市排水工程的规划和设计。随着城市的不断发展，人口的不断增加，...
