摘 要本设计为拟建的市第六污水处理厂工艺设计，处理规模为 10 万 m3/d，设计出水水质执行《城镇污水处理厂污染物排放标准》GB18918-2024 一级 B标准。经查阅资料和现场调研，通过工艺比选，确定采纳卡鲁塞尔氧化沟为市第六污水处理厂的主体处理工艺，该工艺具有处理流程简单、操作管理方便、出水水质好、工艺可靠、建设投资省和运行费用低等优点。在此基础上，确定了污水处理流程为：进水井→粗格栅→提升泵房→细格栅→曝气沉砂池→氧化沟→二沉池→接触池；污泥处理流程为：剩余污泥泵房→浓缩池→贮泥池→脱水间。进行了各单体构筑物的工艺设计和计算，污水处理厂的平面布置，水力计算和高程设计等。在此基础上，完成了平面图、高程图以与主要构筑物的设计和图纸绘制。本工程的实施将显著改善受纳水体水质，同时间接产生经济效益，促进经济可持续进展。关键词：城市污水；卡鲁塞尔氧化沟；工艺设计Abstract The project is the process design of Sixth Sewage Treatment Plant to build in Xi'an. Treatment capacity is 100000m3/d. The water quality in effluent will meet the requirement of the State Discharging Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2024) 1B. Though resourcing data and investigation and some comparison,this design uses Carrousel oxidation ditch process. the process has some advantages like easy operation and management,processreliability,saving investment, good treatment effect, and so on 。 On this basis, determined the sewage treatment process for:well of water→thick grille→aeration sink sand pool→oxidation ditch→secondary sedimentation tank→contact chamber ； The sludge treatment process for:excess sludge pump room→concentrated tank→mud storage pool→between dehydration 。 The plan layout of the structures of the monomer process design and calculation, sewage treatment plant, the hydraulic calculation and elevation design, etc.Based on this,this design contains the identification, each monomer process of calculation, construction...
