摘　　要：广州空港花山净水厂一期工程设计处理规模为7万m^(3)/d。采用全地下式通透式空间设计,主工艺为可变AAO-AO+高负荷复合式沉淀池+微砂高效沉淀池+反硝化深床滤池,出水水质满足准Ⅳ类稳定达标排放。通过可切换的低碳工艺组合运行和精准调控策略实现低碳运行;通过高负荷二沉池和操作层多功能模块叠合节省用地;立体通透空间设计实现建筑、通风及照明节能;臭气处理采用双层密封加盖收集处理+分区复合式处理工艺分区稳定达标排放。地面为全开放式景观+体育公园,地面景观延申至地下空间,运营环境舒适,项目综合用地指标仅0.214 m^(2)/m^(3)污水。The first phase of the Guangzhou Airport Huashan Water Treatment Plant has a designed processing capacity of 70000 m^(3)/d.It adopts a fully underground permeable space design,with the main process consisting of"AAO-AO+high-load composite sedimentation tank+microsand efficient sedimentation tank+denitrification deep bed filter."The effluent water quality surpasses Class IV standards,ensuring stable compliance with discharge regulations.Low-carbon operation is achieved through a switchable combination of low-carbon processes and precise control strategies.Land is conserved through the integration of a high-load secondary sedimentation tank and multifunctional modules in the operational layer.Energy efficiency is enhanced through threedimensional transparent space design for architecture,ventilation,and lighting.Odor control involves a double-sealed cover for collection and processing,utilizing a partitioned composite treatment process for stable and compliant emissions in different zones.The ground area features an open landscape and sports park,extending the landscape design to the underground space for a comfortable operating environment.The comprehensive land use index for the project is only O.214 m^(2)/m^(3) of wastewater.
